} | This study attempts to resolve some of the disparity between lifestyle/routine activities theory and empirical findings concerning the elderly victim of homicide. Analysis of Canadian data leads to the conclusion that the elderly are disproportionately victims of theft-based homicide, a finding not consistent with the routine activity approach. A reformulation of the theory resolves the theory/data gap. | 2022-12-20T03:43:17.530Z |

} | Purpose: Inadequate sleep, whether it is caused by voluntary sleep curtailment or specific sleep disorders, is highly prevalent, has wide-ranging negative consequences for human health and well-being, and is greatly under-diagnosed. The objective of this study was to determine the frequency of inquiry by family medicine clinics about unhealthy sleep patterns and symptoms in their health history database questionnaires. Methods: This study surveyed health history database forms used by family medicine clinics in the 7-county Minneapolis/St. Paul metropolitan area for questions related to sleep disorders. Fourteen distinct database batteries that are used in 121 primary care clinics and employ 935 family medicine doctors (roughly 75% of physicians practicing in this region) were analyzed. Results: Direct questions about sleep health are often not included in health history questionnaires. Eight of 14 (57%) database batteries reviewed in this study featured no sleep-related questions. Other lifestyle issues were screened with much greater frequency. For example, questions about healthy eating patterns and regular physical activity were present in 13 and 12 of the 14 batteries (93% and 86%), respectively. Conclusions: Despite the significant burden that sleep disorders place on human health, this study found that family medicine clinics do not screen for them as frequently as they do for other lifestyle/behavioral issues when they establish a health history database for new patients. | 2022-12-20T13:31:38.582Z |

} | Purpose To determine the long-term ocular complications and visual outcome in patients with necrotising herpetic retinitis (NHR).
Methods 26 patients (33 eyes) with NRH diagnosed between June 1987 and January 2002 at Pitie-Salpetriere Hospital, in Paris, France, were retrospectively reviewed. Demographic data, clinical presentation, viral identification (when possible), initial therapeutic management, long-term antiviral therapy, complications and final visual acuity were analyzed.
Results 16 patients (61.5%) were male, 10 (38.5%) were female. Age ranged from 11 to 67 years (mean 40.6 years). All patients were treated with intensive intravenous antiviral therapy, 9 (34.6%) with additional intravitreous ganciclovir injections. At last examination, 20 patients (76.9%) were still under prophylactic antiviral treatment. Complications were cataract (63.6%), retinal detachment (48.5%), recurrence (33.3%), macular edema (36.4%), optic atrophy (30.3%) and epimacular membrane (27.3%). Final visual acuity was below 20/200 in 15 eyes (45.5%). The minimal follow-up was 3 years.
Conclusion Despite aggressive antiviral therapy, visual prognosis remains guarded in patients with NHR. Retinal vasculopathy and optic disc alterations are major factors to consider in order to improve the visual outcome. | 2022-02-11T10:37:14.183Z |

} | The [3+2] cycloaddition (32CA) reactions of C-cyclopropyl-N-methylnitrone 1 with styrene 2 have been studied within molecular electron density theory (MEDT) at the B3LYP/6-311++G(d,p) level of theory. These zwitterionic type 32CA reactions occur through a one-step mechanism. The 32CA reactions undergo four stereoand regioisomeric reaction paths to form four different products, 3, 4, 5 and 6. Analysis of the conceptual density functional theory (CDFT) indices predict the global electronic flux from the strong nucleophilic nitrone 1 to the styrene 2. These 32CA reactions are endergonic with reactions Gibbs free energies between 2.83 and 7.39 kcal.mol in the gas phase. The 32CA reaction leading to the formation of cycloadduct 3 presents the lowest activation enthalpy than the other paths due to a slightly increase in polar character evident from the global electron density transfer (GEDT) at the transition states and along the reaction path. The bonding evolution theory (BET) study suggests that these 32CA reactions occur through the coupling of pseudoradical centers and the formation of new C-C and C-O covalent bonds has not been started in the transition states. | 2022-09-13T04:01:19.406Z |

} | Purpose of reviewThe increasing recognition of the role of nutritional care for preterm infants continues to result in a proliferation of review articles, systematic reviews, observational studies and trials. In this article, we review a selection of important studies published in the last 12–18 months. Recent findingsThe selected studies demonstrate the potential importance of light protecting parenteral nutrition solutions, the benefits of standardized concentrated parenteral nutrition solutions and the importance of insulin-like growth factor I in early life. Trials of immunonutrients (such as bile salt-stimulated lipase) and other bioactive peptides such as lactoferrin are in progress, and emerging data highlight the importance of vitamin D for immune regulation, and therefore its role in sepsis and gut function. Early oro-pharyngeal administration of colostrum appears to safely improve early immune development, and supports the increasingly common practice of immediate commencement of mothers’ own breast milk. Despite this, studies continue to show that breastfeeding continuation rates could be improved. Data also highlight the potential role of macronutrient supply on other functional outcomes, such as retinopathy of prematurity. Finally, the importance of the unique nutritional needs of late and moderately preterm infants is starting to be recognized – a much larger group than the extremely preterm infants in whom many studies are focused. SummaryEarlier, more aggressive nutrient supply and feeding regimes, including optimal support of breastfeeding mothers to ensure adequate provision of own mother's milk, appear to improve growth and neurodevelopmental outcomes. The addition of bioactive proteins shows promise. Special focus needs to be reestablished for late and moderately preterm infants, who have particular nutritional and feeding support requirements. This review has highlighted the need for further research particularly in the areas of early parenteral nutrition, the optimal regime to improve early growth and neuronal effects, the optimal rate of growth and/or catch-up, and the role of immune nutrients. | 2022-10-27T20:27:36.744Z |

} | The classes of Monge-Amp\`ere systems, decomposable and bi-decomposable Monge-Amp\`ere systems, including equations for improper affine spheres and hypersurfaces of constant Gauss-Kronecker curvature are introduced. They are studied by the clear geometric setting of Lagrangian contact structures, based on the existence of Lagrangian pairs in contact structures. We show that the Lagrangian pair is uniquely determined by such a bi-decomposable system up to the order, if the number of independent variables $\geq 3$. We remark that, in the case of three variables, each bi-decomposable system is generated by a non-degenerate three-form in the sense of Hitchin. It is shown that several classes of homogeneous Monge-Amp\`ere systems with Lagrangian pairs arise naturally in various geometries. Moreover we establish the upper bounds on the symmetry dimensions of decomposable and bi-decomposable Monge-Amp\`ere systems respectively in terms of the geometric structure and we show that these estimates are sharp (Proposition 4.2 and Theorem 5.3). | 2022-11-11T08:10:20.809Z |

} | The purpose of this study is to discover the most relevant psychopathological features of maladaptive disorders arising under the influence of psycho-emotional stress in the student community and associated with consequences of military conflict, and identify potential diagnostic and treatment-rehabilitation measures for improving effectiveness of their primary, secondary and tertiary prevention in future. The study was conducted in 4 stages on the basis of an adapted questionnaire and a set of psychometric methods, involving 249 adult students (over 18 years), including a group of respondents at greatest risk – and namely students who are internally displaced persons and students children of anti-terrorist operation participants. The studies have shown a decrease in psychological well-being, the predominance of leading psychopathological symptoms of anxiety, lack of interest in life, lack of motivation, loss of vital energy, feelings of hopelessness, suicidal thoughts, somatic symptoms in the form of disorders of the cardiovascular, gastrointestinal systems, higher medium severity levels of asthenic manifestations; worse than the general indicator of quality of life among the respondents of the main group. Inverse correlation between a high level of state anxiety (r= -0.6) and trait anxiety (r= -0.45) and a low level of mental well-being has been proved. The obtained results can be used to substantiate and continue transformation of the system of social and medical support in health care, in particular when developing measures aimed at preventing development of non-psychotic mental disorders among students in Ukraine, which will optimize human resources and further health improvement of student youths. | 2022-12-10T09:06:27.239Z |

} | Kellogg, E, Cantacessi, C, McNamer, O, Holmes, H, von Bargen, R, Ramirez, R, Gallagher, D, Vargas, S, Santia, B, Rodriguez, K, and Astorino, TA. Comparison of psychological and physiological responses to imposed vs. self-selected high-intensity interval training. J Strength Cond Res XX(X): 000-000, 2018-High-intensity interval training elicits similar physiological adaptations as moderate intensity continuous training (MICT). Some studies report greater enjoyment to a bout of high-intensity interval exercise (HIIE) vs. MICT, which is surprising considering that HIIE is more intense and typically imposed on the participant. This study compared physiological and perceptual responses between imposed and self-selected HIIE. Fourteen adults (age = 24 ± 3 years) unfamiliar with HIIE initially performed ramp exercise to exhaustion to measure maximal oxygen uptake (V[Combining Dot Above]O2max) followed by 2 subsequent sessions whose order was randomized. Imposed HIIE consisted of eight 60 seconds bouts at 80 percent peak power output (%PPO) separated by 60 seconds recovery at 10 %PPO. Self-selected HIIE (HIIESS) followed the same structure, but participants freely selected intensity in increments of 10 %PPO to achieve a rating of perceived exertion (RPE) ≥7. During exercise, heart rate, V[Combining Dot Above]O2, blood lactate concentration (BLa), affect (+5 to -5), and RPE were assessed. Physical Activity Enjoyment Scale was measured after exercise. Results showed higher V[Combining Dot Above]O2 (+10%, p = 0.013), BLa (p = 0.001), and RPE (p = 0.001) in HIIESS vs. HIIEIMP, and lower affect (p = 0.01), and enjoyment (87.6 ± 15.7 vs. 95.7 ± 11.7, p = 0.04). There was a significantly higher power output in self-selected vs. imposed HIIE (263.9 ± 81.4 W vs. 225.2 ± 59.6 W, p < 0.001). Data suggest that intensity mediates affective responses rather than the mode of HIIE performed by the participant. | 2022-12-10T18:53:35.872Z |

} | Cisplatin is a potent chemotherapeutic used for the treatment of many types of cancer. However, its dose-limiting side effect is nephrotoxicity leading to acute kidney injury (AKI). Patients who develop AKI have an increased risk of mortality and are more likely to develop chronic kidney disease (CKD). Unfortunately, there are no therapeutic interventions for the treatment of AKI. It has been suggested that the lack of therapies is due in part to the fact that the established mouse model used to study cisplatin-induced AKI does not recapitulate the cisplatin dosing regimen patients receive. In recent years, work has been done to develop more clinically relevant models of cisplatin-induced kidney injury, with much work focusing on incorporation of multiple low doses of cisplatin administered over a period of weeks. These models can be used to recapitulate the development of CKD after AKI and, by doing so, increase the likelihood of identifying novel therapeutic targets for the treatment of cisplatin-induced kidney injury. | 2022-12-18T14:31:21.860Z |

} | Climacteric fruit ripening, as it occurs in many fruit crops, depends on a rapid, autocatalytic increase in ethylene production. This agriculturally important process has been studied extensively, with tomato simultaneously acting both as a model species and target crop for modification. In tomato, the ethylene biosynthetic genes ACC SYNTHASE2 (ACS2) and ACS4 are highly expressed during fruit ripening, with a combined loss of both ACS2 and ACS4 activity preventing generation of the ethylene burst necessary for fruit ripening. However, the individual roles and importance of ACS2 and ACS4 have not been determined. In this study, we examined specifically the role of ACS4 by comparing the phenotype of an acs4 mutant firstly with that of the wild-type, and secondly with two novel ripening-inhibitor (rin) mutants. Ethylene production during ripening was significantly reduced in both acs4-1, and rin lines, with rin genotypes showing the weaker ethylene burst. Also i) the time between anthesis and the start of fruit ripening and ii) the time required to progress through ripening were significantly longer in acs4-1 than in the wild type, but shorter than in the strongest rin mutant. The delay in ripening was reflected in the lower expression of ripening-related transcripts during the mature green and light red ripening stages. Furthermore, expression of ACS2 and ACS4 was strongly dependent on a functional RIN gene, while ACS2 expression was largely independent of ACS4. Altogether, we show that ACS4 is necessary for normal progression of tomato fruit ripening and that mutation of this gene may provide a useful means for altering ripening traits. | 2022-12-18T22:49:46.976Z |

} | The effects of two different methods of cricoid pressure on laryngoscopic view were studied in 94 healthy women presenting for routine gynaecological surgery. Laryngoscopy was performed with either single‐handed or bimanual cricoid pressure; after grading of the view obtained, the other method was used and a second grading performed. Laryngoscopic view was better with the bimanual than with the single‐handed technique (p = 0.016). In 21 cases, a better laryngoscopic view was obtained with the bimanual technique; in eight cases it was better with the single‐handed technique; and in 65 cases, the method of cricoid pressure made no difference. Age, weight, Mallampatti score and thyromental distance did not differ between patients in these three groups. Bimanual cricoid pressure should be the initial technique of choice during rapid sequence induction but, in a minority of cases, switching to a single‐handed technique may improve the laryngoscopic view. The technique of cricoid pressure which produces the best laryngoscopic view in an individual patient cannot be predicted from the physical features studied. | 2022-12-31T05:59:02.034Z |

} | The practice of using green manure provides for the better utilization of chemical fertilizers and a lower cost of mineral fertilizers, and it promotes an increase in the soil’s biological activity. Green house experiment was conducted to evaluate the effect of different phosphorus sources and lime on pigeon pea growth and their effects as green manures on the dry matter production of green corn. The experiment was conducted in a greenhouse of the Federal University of Mato Grosso, Rondonopolis campus, from May 2011 to May 2012. Two sources of phosphorus (rock phosphate and triple superphosphate) were used with and without liming. The treatments were assigned in completele randomised design (CRD) with twelve replicates, the treatments (contro), rock phoshate and triple super phoshate with and without liming formed the bases of the experiment. The phosphorus was incorporated into the soil with 200 mg dm-3 of phosphorus (P2O5) based on the availability of phosphate in the sources, that is, triple superphosphate (44% P2O5) and rock phosphate Bayovar (29% P2O5) and the method of lifting the base saturation of 60%. The experiment was conducted in two phases: pigeon pea variety cv. BRS Mandarim was cultured in the first one, and the corn was variety cv. AG1051 grown in the soil under the residual effect of the first culture. Liming and rock phosphate provide a greater dry mass of pigeon pea leaves. In the presence of lime, triple superphosphate increased pigeon pea shoot and root dry weight. The cultivation of corn after pigeon pea fertilized with triple superphosphate and rock phosphate in the presence of lime, induced the dry matter production of corn.

} | Glial cell line-derived neurotrophic factor (GDNF) is one of the most studied neurotrophic factors. GDNF has two splice isoforms, full-length pre-α-pro-GDNF (α-GDNF) and pre-β-pro-GDNF (β-GDNF), which has a 26 amino acid deletion in the pro-region. Thus far, studies have focused solely on the α-GDNF isoform, and nothing is known about the in vivo effects of the shorter β-GDNF variant. Here we compare for the first time the effects of overexpressed α-GDNF and β-GDNF in non-lesioned rat striatum and the partial 6-hydroxydopamine lesion model of Parkinson's disease. GDNF isoforms were overexpressed with their native pre-pro-sequences in the striatum using an adeno-associated virus (AAV) vector, and the effects on motor performance and dopaminergic phenotype of the nigrostriatal pathway were assessed. In the non-lesioned striatum, both isoforms increased the density of dopamine transporter-positive fibers at 3 weeks after viral vector delivery. Although both isoforms increased the activity of the animals in cylinder assay, only α-GDNF enhanced the use of contralateral paw. Four weeks later, the striatal tyrosine hydroxylase (TH)-immunoreactivity was decreased in both α-GDNF and β-GDNF treated animals. In the neuroprotection assay, both GDNF splice isoforms increased the number of TH-immunoreactive cells in the substantia nigra but did not promote behavioral recovery based on amphetamine-induced rotation or cylinder assays. Thus, the shorter GDNF isoform, β-GDNF, and the full-length α-isoform have comparable neuroprotective efficacy on dopamine neurons of the nigrostriatal circuitry. | 2022-12-07T17:31:49.077Z |

} | Abstract The aim of this study was to determine the frequency of ocular symptoms and compare the demographic and clinical characteristics in AR patients depending on sensitisation to various types of aeroallergens. Allergic rhinitis is defined as an IgE-mediated inflammation of the lining of the nose that is characterized by nasal symptoms, including nasal congestion, sneezing, itching of nose and runny nose. Patients suffering from allergic rhinitis frequently experience ocular symptoms such as ocular redness, eye itching and tears. The frequency of ocular symptoms in our study population was 27,6%. No statistical significance was found in the mean ages of the patients who did or did not experience ocular symptoms p>0,05 (p=0,243). Our results indicated that there were no statistical differences (p>0,05) among the groups of allergic rhinitis patients based on experiencing nasal symptoms according to the types of aeroallergens. Our results indicated that there were significant experiences of ocular symptoms in patients who were sensitised to outdoor aeroallergens (p<0,001) and significant sensitisation to both outdoor and indoor aeroallergens (p<0,05). Experiencing the examined ocular symptoms, including ocular redness, eye itching and tears, demonstrated highly statistical significance (p<0,001) among the groups of allergic rhinitis patients who were sensitised to indoor aeroallergens and outdoor aeroallergens, and there was statistical significance (p<0,05) among the groups of allergic rhinitis patients who were sensitised to indoor aeroallergens and both types of aeroallergens (indoor and outdoor). Ocular symptoms are more common in patients who are sensitised to outdoor aeroallergens. | 2022-12-10T13:28:08.442Z |

Results showed that elderly women were more at risk than men for long-term benzodiazepine use. Results of the multivariate logistic regression did not show a significant difference between women and men on any of the risk factors studied. Other factors such as elderly and physician attitudes deserve further study to explain differences in long-term benzodiazepine use between elderly women and men. | 2022-12-13T15:17:31.057Z |

} | In this paper, we present a novel FPGA-based high-throughput beamforming MIMO receiver for millimeter wave mobile communication. With vast spectrum and small antenna element size, millimeter wave communication becomes very attractive and promising to support next generation mobile communication (5G). However, the high data rate requirement challenges both algorithm and architecture. In order to support the high data rate and to reduce the overhead of selecting the best beam pair, we propose a novel beamforming synchronization scheme more suitable for mobile communication. By further optimizing the algorithm and the architecture, we present a complete mobile receiver based on FPGA, which includes RF frontend, ADC, beamforming control, synchronization, channel estimator, soft MAP detector, and channel decoder. The design operates at 28 GHz carrier frequency with 500 MHz bandwidth. The throughput can reach 1.52 Gbps. We also performed the indoor and outdoor over-the-air transmission field tests. This work provides a platform for future millimeter wave mobile communication research. | 2022-12-15T09:00:11.261Z |

} | Objective. From January 2007 to December 2008, the Montréal Public Health Department sent postal questionnaires to physicians and conducted patient interviews for all those newly diagnosed with hepatitis C virus (HCV) infection. We evaluated physician responses to risk factor questions for non-acute HCV cases. Methods. We compared physician and patient responses with each of nine risk factor questions, determined the sensitivity and specificity of physician responses compared with patient responses, and evaluated agreement using Gwet's agreement coefficient (AC1). We ranked risk factors and compared the distributions by principal exposure category according to physician reporting vs. patient interview using the Chi-square test. Results. The completeness of physicians' responses (yes, no, or unknown) varied by risk factor question from 90.8% to 96.7%. For risk factors present among more than 5% of cases, sensitivity of physician responses ranged from 26.9% to 87.7% and specificity ranged from 93.0% to 98.6%. The AC1 coefficients for agreement between physician and patient responses to lifetime risk factors considered most important in HCV acquisition were 0.80 for injection drug use, 0.95 for blood transfusion before 1990, and 0.86 for birth in a country with high HCV prevalence. Risk distributions by principal exposure category according to physician reporting vs. patient interview were not statistically different (χ2[4] = 2.17, p=0.704). Conclusion. Postal questionnaires completed by physicians appear valid for determining the principal exposure category among non-acute HCV cases. Physician reporting can be a useful and low-cost component of routine HCV surveillance. | 2022-09-08T18:19:52.760Z |

In this sense, the research analyzes the legality of startups, the social responsibility and solidarity of the same and its legal nature implemented in the country order, verifying if this framework is sufficient to support the new business model. The study is justified because of the relevance and contemporaneity of the theme, since with the entrepreneurship and innovation aspect the startups become a new relevant business phenomenon in the country. Therefore, we will use the hypothetical-deductive approach method, added to the bibliographic research method. It is concluded that startups are innovative enterprises, which are based on economic and social transformations, fulfilling their social and solidarity function as a company. | 2022-10-14T01:25:32.420Z |

} | It is shown, that different resonances of close dual-post configurations can be utilized for dual-band filter designs. The resonances of close dual-post arrangements are no longer the resonances of the individual posts because of the strong coupling. The independent control of these dual-post resonances is one prerequisite for the design of the novel dual-band filters. The second one is the independent control of interface and inter-resonator couplings of the different resonances. Thus, possible measures that allow the individual adjustment of resonances and couplings for a dual-band filter design are introduced. The general feasibility of this novel approach is demonstrated by a dual-band filter design at 2.5GHz providing two 4-order filter characteristics. | 2022-12-03T11:26:12.314Z |

} | MEGARA is an integral-field and multi-object medium-resolution spectrograph for the GTC 10.4m telescope, which was commissioned on June - August 2017. MEGARA offers two observing modes, the LCB mode, a large central IFU; and a Multi-Object Spectrograph (MOS) mode, composed by 92 robotic positioners carrying 7-fiber minibundles each. This paper presents the models and measurements developed for the alignment between the image of the telescope pupil and the 100-μm fiber cores during the integration and verification at the laboratory. On the one hand, the error in the positioner-minibundles assembly was optimized with the aim of achieving a fiber-to-fiber flux homogeneity better than 10%. On the other hand, the positioner pointing was characterized in order to achieve a pointing precision of 1/5 of the spaxel size (which has been designed to be 0.62 arcsec). The on-sky measurements obtained during the commissioning to verify our laboratory results are also presented. | 2022-12-15T04:00:49.300Z |

} | In spite of the availability of high-tech devices for wound assessment, plastic surgeons recognize that the Color and confluence of granulation tissue are the most important indicators of open-wound healing. We developed a simple and inexpensive pocket-size scale–4he Granulometer–to facilitate a firier assessment and to standardize the documentation of wound healing. This device overcomes limitations set by conditions such as lighting or recent exposure to other wounds that could distort the examiner's perception of the wound in question. In this study we examined the inter- and intraobserver variations in judgment, and the validity of the Granulometer. Our results demonstrate that skin graft viability can be predicted accurately by this eight-grade scale. Since graft survival depends on proper wound healing, we believe that the Granulometer can also be used for fine assessment of wound treatmeht. the low inter- and intraobserver variations indicate that the Granulometer measurements are both reproducible and accurate. | 2022-12-13T01:39:19.223Z |

Iodine-123 iodoamphetamine single photon emission computed tomography showed hypoperfusion in the whole brain, but cerebral blood flow increased dramatically after the administration of acetazolamide in the cerebral cortex. Lomerizine, a diphenylmethylpiperazine Ca2+ channel blocker, can selectively increase cerebral blood flow. Cognitive decline and cerebral hypoperfusion improved during 2-year administration of lomerizine in this CADASIL patient, and thus, lomerizine is a potential candidate for treating cognitive impairment in CADASIL patients. | 2022-09-12T00:40:16.766Z |

} | Bony fishes add sensory hair cells to the saccule and lagena of the ear for at least several years after hatching. However, it is not known whether hair cell proliferation occurs for the whole lifetime of an animal, whether proliferation occurs in all endorgans of the ear, or whether the rate of proliferation is the same in all of the endorgans. To obtain answers to these questions, the extent of postembryonic hair‐cell proliferation was determined in the saccule, lagena, and utricle of the ear in the European hake, Merluccius merlaccius, for fish ranging from 7 to 75 cm in total length (6 months to 9 years of age). Results demonstrated that hair‐cell addition continued throughout this period in all three otic endorgans, although endorgan size was proportionally greatest in smaller animals. Of the three endorgans, cell addition was greatest in the saccule. Moreover, far more cells were added to the caudal end of the saccule than to the rostral end. Each saccule of the largest hake had over 900,000 hair cells. It is estimated that each saccule adds approximately 110,000 new hair cells each year (or 302 cells/day) over the life span of the fish studied. A significant number of small ciliary bundles, thought to represent newly proliferated hair cells, was found throughout each endorgan, and the number of such bundles declined as the rate of hair cell proliferation decreased. The results demonstrate that extensive proliferation occurs in all three otolithic endorgans of the ears in a fish and that such proliferation continues for virtually the whole life of the animal. The functional significance of this addition is not known. © 1994 Wiley‐Liss, Inc. | 2022-12-20T08:30:01.502Z |

The title of a recent study of The Marriage of Mr. Mississippi, for example-“Tragic Elements of a Duerrenmatt Comedy"-is significant in that it indicates the fusion of the two extremes of dramatic composition. The Physicists, which is again styled a comedy by its author, represents a converse of this formulation.

} | The solid oxide fuel cell (SOFC) is known as the most hopeful clean energy source in the 21st century due to its higher efficiency and lower pollution, but its performance degradation and durability have become bottlenecks hindering its large-scale commercialization. Accurately predicting the performance degradation trend of SOFC and timely diagnostic failures can maintain and adjust the equipment in advance, which is conducive to extending its service life. Data-driven and model-based both have certain limitations, and they are two traditional prediction methods. This paper proposes a solid oxide fuel cell hybrid prediction method based on the combination of empirical model and data-driven. Model-based prediction can capture the degradation trend of voltage. Data-driven prediction can describe local nonlinear characteristics in the degradation process. Then, according to the dynamically adjusted weight factor, the results predicted by the different methods are merged to get the culminating prediction result. Finally, the experimental results indicate the hybrid prediction method has higher forecasting accuracy. | 2022-09-30T04:56:52.855Z |

Introduction: CDI is common after alloHCT mainly due to the frequent use of antibiotics before and during transplant. CDI is reported in 13 to 18% of recipients after alloHCT and in 6 to 8% after autologous HCT, mainly in the first-month post HCT. The determination of incidence and impact of CDI on HCT outcomes will help further our understanding towards the prevention and management of CDI post HCT.
Methods: Using the CIBMTR dataset, we examined all patients aged two years and older who received first alloHCT for acute myeloid leukemia (AML), Acute Lymphocytic leukemia (ALL), or myelodysplastic syndrome (MDS) from related or unrelated donors between 2013 and 2018 at US centers. Stem cell sources included HLA-matched marrow, peripheral blood (PBSC), and umbilical cord blood (UCB) (4/6 or higher). The objective was to study the impact of CDI by day 100 on transplant outcomes by one year compared to the control cohort (without documented CDI from the same centers). Multivariable analyses were performed using Cox proportional hazard model for overall survival (OS), disease-free survival (DFS), Transplant related mortality (TRM), Infection-related mortality (IRM), chronic GVHD, and relapse. Both aGVHD preceding CDI and CDI preceding aGVHD were analyzed. Due to overlap in the onset of CDI and aGVHD, an interaction of these time-dependent events in some models were noted necessitating incorporation of a composite variable (CV - CDI+aGVHD) for OS, TRM, IRM, and cGVHD models.
Results: A total of 826 patients with CDI and 6723 controls from 127 centers were analyzed. The cumulative incidence of CDI by day 100 following alloHCT was 18.7% (99% CI: 15% - 22.7%) and 10.2% (99% CI: 9.2% - 11.1%) in pediatric and adult patients, respectively [Figure 1]. The median time to diagnosis of CDI was 13 days (0 - 100). Recurrent CDI by 1 year occurred in 15% of patients. Myeloablative conditioning with total body irradiation (compared to Reduced-intensity/non-myeloablative (RIC/NMA) conditioning) and lower gastrointestinal GVHD preceding the diagnosis of CDI were risk factors for CDI. A diagnosis of MDS was associated with a lower risk of CDI. There was significant overlap in the onset of aGVHD and CDI [Figure 2] such that for patients with both CDI and aGVHD [n=378], 115 (30%) had aGVHD prior to CDI, and 70% were diagnosed with CDI first.
CV - CDI + aGVHD was associated with a statistically significant increase in IRM and TRM and a decrease in OS. Specifically, CDI was associated with a 2.58-fold [99% CI: 1.43 - 4.66; p<0.001] increase in IRM which increased to >4 fold when CV-CDI + aGVHD was considered, irrespective of whether aGVHD preceded CDI or vice versa [CDI first: 4.88 (99% CI: 2.38 - 9.97), p<0.001; aGVHD first 4.15 (99% CI: 1.46 - 11.80), p = 0.0005]. CDI alone was not associated with increased risk of cGVHD [0.85 (99%CI: 0.66-1.09), p=0.0921], and the CV - CDI+aGVHD had similar risk of cGVHD as aGVHD without CDI. CDI had no impact on relapse or DFS.
Conclusion: CDI tightly overlaps with aGVHD. Not surprisingly, the combination of CDI and aGVHD is associated with decreased overall survival and increased TRM. More concerning is that patients having both aGVHD and CDI had a >4-fold increased risk of death due to any infection. Our results highlight the burden and impact of CDI after alloHCT and the critical need to develop new/improved strategies for prevention in alloHCT recipients.

} | Sparassis species show extensive morphological variation, especially when materials from eastern Asia and Australia are compared with collections from North America and Europe. We have been studying the taxonomy of Sparassis from eastern Asia, North America, Australia and Europe, using both morphological and molecular data. DNA was extracted from 32 recent collections of Sparassis from Australia, Canada, China, Finland, France, Germany, Japan, Switzerland, Thailand, the United Kingdom and the United States. The report of a Sparassis taxon from Australia is the first report of this genus from the Southern Hemisphere. Sequences of nuclear and mitochondrial rDNA and the gene encoding RNA polymerase subunit II (RPB2) were used to examine relationships both within the genus Sparassis and between Sparassis species and other members of the polyporoid clade. Equally weighted parsimony analyses and Bayesian analyses were performed using independent datasets and combined datasets of sequences from different regions. Our results suggest that: (i) Polyporoid fungi producing a brown rot may form a clade; (ii) as suggested in a previous study, Sparassis and Phaeolus form a monophyletic group, which is united by the production of a brown rot, the presence of a bipolar mating system and the frequent habit of growing as a root and butt rot on living trees; (iii) at least seven lineages are within Sparassis, represented by S. spathulata, S. brevipes, S. crispa, S. radicata and three taxa that have not been described, which can be distinguished on the basis of fruiting body structure, presence or absence of clamp connections, presence or absence of cystidia and spore size. | 2022-12-18T03:29:15.025Z |

} | For optoelectronic devices, an attractive research field involves the flexible adjustment of the band gap in semiconductor quantum well (QW) structures by strain engineering. However, rigid wafer-based technology enables lattice-misfit strain during epitaxial growth, which is biaxial, unchangeable, and not sufficient for the devices fitted on various irregular surfaces. Therefore, exploiting the strain produced by externally deformed configurations offers unique opportunities to continuously and non-defectively tune the QW's band structure. Here, we propose a strategy to induce uniaxially distributed strain in elaborately designed wavy quantum well nanoribbons (QWNRs). Meanwhile, a numerically solved strain-photonic coupling model based on the theory of elasticity and the eight-band k·p method is established to illustrate the strain distribution coupled with the strain-induced band gap shift of the wavy QWNR. The μ-photoluminescence measurements reveal a periodically varied band gap in the QW along the uniaxial tensile direction, which is consistent with the result of theoretical calculations. This model demonstrates the potential application of a wrinkled configuration in arbitrarily controlling and tuning the band gap and thus the optoelectronic performances of quantum well systems. | 2022-03-30T22:09:47.336Z |

} | Though the characteristics of pre-Islamic ghazal have often been summarily discussed, its development and evolution in the early period of Islam and the Umayyad age have not hitherto received the attention they deserve and it is hoped that this thesis will form a contribution to the subject and to the study of Arabic literature generally. It is claimed, despite objections which have been raised, that pre-Islamic poetry is authentic. This study shows that pagan ghazal reflected the life of its composers, their environment and the social life of the time. It was composed by people whose personality was not divided by religion into soul and body; who understood love as youthful dalliance, who did not separate it from pleasure, and who enjoyed it as much as their desert, tribal life, and lack of culture allowed. Islam brought about great changes. As far as emotional life was concerned, it became richer, deeper, and more intense. Conversly it brought about a strict morality which stopped the development of ghazal for a while. Thereafter ghazal could not begin developing again before the Omayyad period when the grasp of religion relaxed somewhat. Then the traditional ghazal flourished again over the Arabian country, except in Hijaz where wealth, idleness, and particular political and social conditions gave birth to the Omarit ghazal which sacrificed true love for pleasure, and united music to poetry. As a reaction against this tendency and as a compromise between love and religion, the 'Udhri ghazal came to life. Its authors took a sacrificial pleasure in unrequited love. These and other features are illustrated and discussed. This study, in a way, shows the development of women's status before and after Islam and the development of the emotional life of the Arabs during the three early periods of their history. | 2022-02-08T22:11:49.916Z |

} | We propose a novel scheme for manipulating a passive object using an active plate. In previous studies, cyclic manipulations that transport objects on a plate, position control of an object on a plate, and juggling have been realized. In most manipulations using plates, object motions in the direction of the gravitational force are not considered. The objective of this study is to control an object’s orientation with respect to the gravitational force direction using an active plate for realizing hitherto unrealized object motion. In this context, a tumble doll, which is a planar rigid sphere, is defined as the object. Motions of the object and active plate are designed to be cyclic. A state vector composed of the object’s angle and angular velocity is defined, and the cyclic motion is expressed as a nonlinear discrete system. Fixed points of the state vector are searched for in the designed cyclic motion. A stability analysis around the fixed points is conducted using a Poincaré map. As a result, the fixed points are shown to be asymptotically stable. Finally, experimental results are used to verify that the object’s angle can be manipulated with the designed cyclic motion using the plate. Graphical Abstract | 2022-09-10T21:29:42.684Z |

} | Arabidopsis mutants resistant to cytokinin (benzyladenine [BA]) have been isolated with the intent to find plants defective in cytokinin perception or response. At low concentrations, BA produces a "cytokinin root syndrome" in which primary root elongation is inhibited, but root hair elongation is stimulated. Five independent mutants that did not express this syndrome in the presence of BA were selected. All five mutants were recessive, and crosses between them indicated that they were in the same complementation group. The genetic locus represented by these mutations has been designated ckr1 and mapped to chromosome 5. | 2022-12-13T04:45:39.036Z |

} | The Parkinson's disease‐associated protein kinase PINK1 and ubiquitin ligase Parkin coordinate the ubiquitination of mitochondrial proteins, which marks mitochondria for degradation. Miro1, an atypical GTPase involved in mitochondrial trafficking, is one of the substrates tagged by Parkin after mitochondrial damage. Here, we demonstrate that a small pool of Parkin interacts with Miro1 before mitochondrial damage occurs. This interaction does not require PINK1, does not involve ubiquitination of Miro1 and also does not disturb Miro1 function. However, following mitochondrial damage and PINK1 accumulation, this initial pool of Parkin becomes activated, leading to the ubiquitination and degradation of Miro1. Knockdown of Miro proteins reduces Parkin translocation to mitochondria and suppresses mitophagic removal of mitochondria. Moreover, we demonstrate that Miro1 EF‐hand domains control Miro1's ubiquitination and Parkin recruitment to damaged mitochondria, and they protect neurons from glutamate‐induced mitophagy. Together, our results suggest that Miro1 functions as a calcium‐sensitive docking site for Parkin on mitochondria. | 2022-12-17T13:14:11.880Z |

} | Abstract The valve morphology of the brackish-water plankton diatom Skeletonema subsalsum is dependent on salinity. In cells grown at salinities of 3‰ or less, the valve faces were flat and the connecting processes much reduced in length. Cells grown at salinities of 5‰ or higher had dome-shaped valves and extended connecting processes. The effect of an increase in salinity could be duplicated by the addition of sucrose to the growth medium. The growth rate was nearly independent of salinity in the range of 1–10‰. It was concluded that the osmotic pressure of the medium exerts a direct effect on cell-wall morphogenesis in S. subsalsum. | 2022-12-19T07:36:44.414Z |

} | BACKGROUND AND OBJECTIVES
Currently, it is controversial on whether neuroaxis block (NB) is more effective than general anesthesia (GA) in elderly individuals undergoing non-cardiac surgeries. The objective of this study was to determine the efficiency of NB in comparison to GA for revascularization of the lower limbs (RLL) in the elderly.
METHODS
A search of the following data base was conducted: MEDLINE (1955 to 2007), CINHAL (1982 to 2007), EMBASE (1980 to 2007), LILACS (1982 to 2007), and ISI (1945 to 2007). Two investigators undertook an independent analysis of the studies published to identify randomized clinical trials (RCTs) comparing NB with GA for RLL. The full text of the RCTs that fulfill the inclusion criteria was analyzed. Disagreements were analyzed in consensus meetings. The software Review Manager was used for the Metanalysis by means of odds ratio with a confidence interval of 95%.
RESULTS
Three studies involving 465 patients were selected. Metanalysis of the following parameters did not show statistically significant differences: mortality (OR: 0.90; CI 95%: 0.30-2.73; p = 0.85 for spinal anesthesia; OR: 1.30, CI 95%: 0.38-4.48, p = 0.68, for epidural block); myocardial infarction (OR: 1.38, CI 95%: 0.29-6.46, p = 0.68); and rate of lower limb amputation (OR: 0.81, CI 95%: 0.30-2.19, p = 0.68, for spinal block; OR: 0.70, CI 95%: 0.24-2.07, p = 0.52 for epidural block). A statistically significant difference was observed for pneumonia (OR: 0.37, CI 95%: 0.15-0.89, p = 0.03); however, clinical heterogeneity was present.
CONCLUSIONS
This metanalysis did not generate enough evidence to demonstrate that NB is more efficient, equivalent, or less efficient than GA for RLL in the elderly. | 2022-12-23T02:06:19.049Z |

} | Breast cancer is one of the most widely recognized diseases after skin cancer. Though it can occur in all kinds of people, it is undeniably more common in women. Several analytical techniques, such as Breast MRI, X-ray, Thermography, Mammograms, Ultrasound, etc., are utilized to identify it. In this study, artificial intelligence was used to rapidly detect breast cancer by analyzing ultrasound images from the Breast Ultrasound Images Dataset (BUSI), which consists of three categories: Benign, Malignant, and Normal. The relevant dataset comprises grayscale and masked ultrasound images of diagnosed patients. Validation tests were accomplished for quantitative outcomes utilizing the exhibition measures for each procedure. The proposed framework is discovered to be effective, substantiating outcomes with only raw image evaluation giving a 78.97% test accuracy and masked image evaluation giving 81.02% test precision, which could decrease human errors in the determination cycle. Additionally, our described framework accomplishes higher accuracy after using multi-headed CNN with two processed datasets based on masked and original images, where the accuracy hopped up to 92.31% (±2) with a Mean Squared Error (MSE) loss of 0.05. This work primarily contributes to identifying the usefulness of multi-headed CNN when working with two different types of data inputs. Finally, a web interface has been made to make this model usable for non-technical personals. | 2022-12-30T00:48:31.282Z |

} | Background Inflammation is a crucial component in carcinogenesis. The neutrophil-to-eosinophil ratio (NER) has been studied as a biomarker of prognosis and predictive of response in metastatic renal cell carcinoma (mRCC). In the present study, we evaluated the relevance of baseline NER on the progression-free survival (PFS) and overall survival (OS) outcomes in real-world patients with mRCC treated with nivolumab in second or subsequent lines. We also assessed the association of baseline NER with objective response, as well as with toxicity and histology. Methods In this multicenter retrospective analysis of patients with mRCC treated with nivolumab, the last systemic absolute neutrophil and eosinophil count before treatment with nivolumab was used to calculate the NER. An additive Cox proportional hazards model was used to identify the cut-off point for NER considering PFS and the patients were allocated into low and high NER groups. Median OS and median PFS were estimated using the Kaplan-Meier estimator, and survival curves of groups were compared using the log-rank test. Univariable and multivariable Cox regression models were used to study OS and PFS and Fisher’s exact test was performed to evaluate the association of NER with the response, toxicity, and histology. Results The 49 analyzed patients had a median follow-up of nine months. The NER cut-off was established at 48, locating 29 patients in the low NER group (NER < 48) and 20 in the high NER group (NER ≥ 48). Median PFS and median OS were significantly shorter in patients with high NER versus low NER (3 vs. 30 months (p < 0.001) and 6 vs. 24 months (p = 0.002), respectively). Multivariable analyses showed that NER (HR 3.92 (95% CI: 1.66-9.23), p = 0.002) was an independent factor for PFS and that NER (HR 3.85 (95% CI: 1.33-11.17), p = 0.013) and progressive disease (HR 5.62 (95% CI: 1.88-16.83), p = 0.002) were independent factors for OS. NER was significantly associated with objective response rate (ORR) (NER ≥ 48-12.5% vs. NER < 48-87.5%, p = 0.003), immune-related adverse events (irAEs) (NER ≥ 48-10.0% vs. NER < 48-42.9%, p = 0.014), and tumor’s histology as patients of high NER group had more non-clear cell carcinoma than low NER group (35.0% vs. 7.4%, p = 0.017). Conclusion Our real-world data analysis of NER in patients with mRCC confirmed the prognostic value of this biomarker, supporting clinical utility in predicting survival. Results also suggested an association between lower NER and better ORR, and that irAEs occur more frequently in patients with a lower NER. However, further large-scale prospective studies are needed to confirm these findings and to validate this biomarker. | 2022-08-19T19:16:15.843Z |

} | Purpose
The purpose of this paper is to explore to what extent a flipped classroom pedagogy (FCP) design as a digital pedagogical tool enhances student teachers’ learning in economics education at an open distance e-Learning (ODeL) university.
Design/methodology/approach
This exploratory study used a quantitative approach and online survey design. The sample consisted of 214 Postgraduate Certificate in Education (PGCE) and 157 Baccalaureus Educationis (BEd) (senior and further education and training phase) student teachers. A closed structured online questionnaire, Flipped Classroom Pedagogy Questionnaire, designed on a four-point Likert scale, was used to collect data. Descriptive and inferential data were computed to explore student teachers’ learning to teach an economics education in a teacher education course. Ethical clearance was granted and therefore adheres to the policy on research ethics of the university.
Findings
Empirically, the findings of this paper revealed that the FCP digital pedagogy enhanced economics students’ academic performance and perceptions in an online open distance learning environment. Furthermore, student teachers perceived that the functionality of the FCP experience as an online strategy was useful and effective for their learning. Therefore, these findings confirmed and extended what is revealed by earlier research studies regarding the debate on the usefulness of the FCP approach as a powerful technology-integrated teaching design in teacher education courses.
Research limitations/implications
The findings of this investigation could not be generalised because a small sample was selected. Further investigation is needed regarding comparing other similar modules of the PGCE/BEd (senior and FET phase) programmes over a longer investigative period in the college. Further research should be explored, employing a mixed-methods approach on how student teachers perceived academic support in the FCP strategy towards self-directed learning.
Practical implications
Ultimately, several implications for using the FCP approach emerged, in particular for rethinking teacher education programmes to support and accommodate the digital learner. To implement this approach successfully, faculties should formulate clear intended outcomes for implementing the FCP pedagogical approach. In addition, faculties at higher education institutions should seriously consider the merits of the FCP approach in order to avoid becoming redundant. Therefore, lecturers who intend to use this strategy either through a contact, blended or ODeL mode of delivery, are compelled to provide consistent, ongoing constructive feedback and monitoring required learning tasks.
Social implications
The paper empowers PGCE/BEd (senior and FET phase) students to teach the subject in a diverse society.
Originality/value
This research study has shown that student teachers perceived an FCP approach in an online platform as an empowering tool that is both effective and useful and that positively impacts on their lived experience in an ODeL context. It extends the epistemology (subject of knowledge) of the effectiveness of the FCP strategy as an enhancer for student learning in an ODeL environment, teacher education in particular. Furthermore, a noteworthy contribution is made towards the application of the FCP as one of the digital pedagogies in teaching economics in an ODeL context. This exploratory study also makes a methodological contribution to the validation of an online data collection instrument for use in future studies. | 2022-12-09T15:49:36.032Z |

} | Product formation, in particular ketohydroperoxide formation and decomposition, were investigated in time-resolved, Cl-atom initiated neopentane oxidation experiments in the temperature range 550-675 K using a photoionization time-of-flight mass spectrometer. Ionization light was provided either by Advanced Light Source tunable synchrotron radiation or ∼10.2 eV fixed energy radiation from a H2-discharge lamp. Experiments were performed both at 1-2 atm pressure using a high-pressure reactor and also at ∼9 Torr pressure employing a low-pressure reactor for comparison. Because of the highly symmetric structure of neopentane, ketohydroperoxide signal can be attributed to a 3-hydroperoxy-2,2-dimethylpropanal isomer, i.e. from a γ-ketohydroperoxide (γ-KHP). The photoionization spectra of the γ-KHP measured at low- and high pressures and varying oxygen concentrations agree well with each other, further supporting they originate from the single isomer. Measurements performed in this work also suggest that the "Korcek" mechanism may play an important role in the decomposition of 3-hydroperoxy-2,2-dimethylpropanal, especially at lower temperatures. However, at higher temperatures where γ-KHP decomposition to hydroxyl radical and oxy-radical dominates, oxidation of the oxy-radical yields a new important channel leading to acetone, carbon monoxide, and OH radical. Starting from the initial neopentyl + O2 reaction, this channel releases altogether three OH radicals. A strongly temperature-dependent reaction product is observed at m/z = 100, likely attributable to 2,2-dimethylpropanedial. | 2022-12-03T13:20:06.302Z |

} | Glyoxal (G) and methylglyoxal (MG) are potentially important secondary organic aerosol (SOA) precursors. Previous studies of SOA formation by G and MG have focused on either species separately; however, G and MG typically coexist in the atmosphere. We studied the formation of secondary organic material in aqueous aerosol mimic mixtures containing G and MG with ammonium sulfate. We characterized the formation of light-absorbing products using UV-vis spectrophotometry. We found that absorption at 280 nm can be described well using models for the formation of light-absorbing products by G and MG in parallel. Pendant drop tensiometry measurements showed that surface tension depression by G and MG in these solutions can be modeled as a linear combination of the effects of G and MG alone. Product species were identified using chemical ionization mass spectrometry with a volatilization flow tube inlet (Aerosol CIMS). Peaks consistent with G-MG cross-reaction products were observed, accounting for a significant fraction of detected product mass, but most peaks could be attributed to self-reaction. We conclude that cross-reactions contribute to SOA mass from uptake of G and MG, but they are not required to accurately model the effects of this process on aerosol surface tension or light absorption. | 2022-12-16T05:38:27.885Z |

} | The frequency and patterns of eyelid opening were examined in a group of neonates (gestational age 24-35 weeks). Observations were spread over the 24 hour period to obtain a complete pattern of events. Mean eyelid closure was 74%. When babies were grouped by gestational age, however, differences became apparent, babies of less than 26 weeks having their eyes shut for only 55% of observations compared with 93% at 28 weeks. Trend analysis confirmed that eyelid closure reached a peak at 28 weeks. Neonates exposed to a day/night regimen, opened their eyes significantly more than those exposed to continuous illumination. We suggest that frequency of eyelid opening may be related both to the infant's developmental state (postmenstrual age) and the illumination of the neonatal unit. Frequency of eyelid opening should therefore be considered when calculating the ocular light exposure of preterm neonates. | 2022-12-30T00:22:23.937Z |

The emergence of these seepages may affect water quality and nutrient pollution in the surrounding by which the distribution is mainly induced by the tidal current regime. This study aimed to determine the influence of tidal current on low-temperature groundwater distribution and to analyze the environmental issues resulted from this phenomenon. Flow model and statistical analysis were employed to determine the transport pattern of SGD. The tidal current moved southwestward during the high tidal condition ranging from 0-0.15 cm/s. While tidal current flowed northeastward during the low tidal condition ranging from 0-0.3 cm/s. The temperature fluctuation follows the changes of surface elevation around SGD in which the correlation value between those two parameters reached 63 percent. This proves that the cold-water transportation depends on the fluctuation of tidal current (tidal pumping), resulting in the imbalanced ecosystem, especially during the high tidal condition when a greater water mass transport takes place.AbstrakKeluaran Air Tanah Lepas Pantai (KALP) telah ditemukan di utara Pulau Lombok. Fenomena ini sangat dipengaruhi oleh daerah aliran air Gunung Rinjani yang meresap dalam bentuk rembesan bawah air. Rembesan terbesar diketahui berada di Pantai Krakas. Kemunculan rembesan ini mungkin berdampak pada kualitas perairan dan polusi nutrien di sekitarnya yang mana distribusinya sangat dipicu oleh pengaruh arus pasang surut. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh dari arus pasang surut terhadap distribusi air dingin dan menganalisis masalah lingkungan akibat dari kondisi tersebut. Arus pasang surut bergerak menuju barat daya saat kondisi pasang berkisar antara 0-0,15 cm/s, sedangkan arus pasang surut bergerak menuju timur laut pada kondisi surut berkisar antara 0-0,32 cm/s. Fluktuasi suhu mengikuti perubahan elevasi muka air di lokasi KALP dimana nilai korelasi dari kedua parameter tersebut mencapai 63 persen. Hal ini membuktikan bahwa transpor air dingin bergantung pada fluktuasi arus pasang surut, menyebabkan ketidakseimbangan ekosistem, khususnya pada kondisi pasang ketika mekanisme transpor masa air yang lebih besar sedang berlangsung. | 2022-01-27T08:14:17.787Z |

A few of the strongest Ni IX and Cu X lines from the former array are also identified. Large irregularities along the isoelectronic sequence are found. Theoretical calculations of atomic energy levels and oscillator strengths helped in the identification of spectral lines. The analysis of the Co VIII spectrum will aid the analysis of the isoelectronic Ni IX spectrum. The latter is important because Ni IX emission lines may be present in solar spectra and are radiated from impurities injected into the plasma produced in the nickel-alloy lined vacuum vessels used in Tokamak devices. | 2022-07-31T20:55:07.410Z |

} | A multiple camera surveillance system is typical example of a Distributed Video (DV) system with many-to-one topology which demands the use of new paradigm with multiple encoders, installed at number of locations and very few decoders in a control room. This paradigm open- up new frontiers for the research community in designing low cost encoders even at the cost of expensive decoders. A solution to this problem based on information theory finding of 70s, by Slepian and Wolf [3], for lossless encoding, and followed by the work of Wyner and Ziv [5], for lossy encoding. In the last few years there has been significant research activity in the design and implementation of video codec based on these findings. Our research work is also part of that effort. In this paper we will present a modified Wyner-Ziv codec, that take advantage of slow motion activity, which is typically of surveillance data. GOP is selected dynamically by accessing motion activity and also puncturing bit rate varies adaptively. Also the proposed architecture takes advantage of intra-frame coding for both key frame and Wyner-Ziv frames. | 2022-02-13T01:56:55.988Z |

} | Time series techniques—particularly impulse–response functions and variance decompositions—are used to characterize the short-run relationships between 17 variables in a vector autoregressive model designed to trace the short-run interconnections among variables affecting lockages on the Mississippi and Illinois Rivers. The model contains five categories of variables: lockages, barge rates, grain bids, rail rates, and rail deliveries. Variance decompositions are constructed that identify barge rates as the most important variable affecting lockages at both short and long horizons. Barge rates are, in turn, explained largely by lockages and rail rates, indicating two-way feedback or bidirectional causality between lockages and barge rates. Impulse–response functions are also examined. The variance decompositions indicate that barge rates are important in explaining lockages, and the impulse–response functions show how lockages and other variables respond to such shocks. In general, there is a substitution away from barge transportation and toward rail transportation when barge rates increase. The results are useful for illuminating the causal relationships among variables in the model and for understanding behavioral relationships present in the data and can be used to guide short- and long-run planning models. For example, many planning models assume that barge traffic does not respond significantly to changes in barge rates; however, results obtained here imply that barge traffic and rail deliveries do respond to such changes. This potentially important implication illustrates the usefulness of the time series techniques used. | 2022-08-30T12:02:32.857Z |

Although he was generally believed to have contracted syphilis while an undergraduate at Oxfordpartly on account of the bad state of his teeth, which was attributed to the mercury he had taken as a cure-no more conclusive evidence of a specific infection is available. Another supposed sign of syphilitic infection has been the rash which troubled him during 1899 and the early summer of 1900, and from which hoe was afforded temporary relief, he believed, as a result of his several public audiences with the Pope. Cawthorne agre-es again with Harris that this was more likely to have been an allergic reaction to shellfish than the manifestation of secondary syphilis; certainly, the timing of its appearance would appear rather unusual if it was the latter. Another possible explanation of the. rash could be that it was dermatitis secondary to vitamin deficiency as a result of exc-essive drinking.

The low-pressure tube furnace is designed to obtain emitter standard sheet resistances of about 60 ohm/sq and wafer uniformity less than 3 %. POCl3 and O2 gas as a precursor for diffusion is described and the thermal behavior of the so called diffusion furnace is studied. A control model has been derived from some previous works to achieve better wafer to wafer temperature distribution. Our result proves that we can target certain electrical properties only by the manipulation and optimization of doping profile and by the addition of multiple temperature ramps to achieve POCl3 diffusion. | 2022-02-12T08:20:10.568Z |

} | Papillary glioneuronal tumor (PGNT) is a low-grade biphasic neoplasm with astrocytic and neuronal differentiation. This tumor occurs most commonly in the frontal and temporal lobes, close to the ventricles, and rarely in the cerebellum, brainstem, and pineal gland. However, there has been no report of this tumor in the suprasellar region to date. In this paper, we report a case of PGNT in the suprasellar region in a 16-year-old girl. Magnetic resonance imaging (MRI) revealed a cystic tumor with calcification that progressed from the anterior skull base to the suprasellar and temporal regions. Preoperatively distinguishing this tumor from craniopharyngioma was difficult because of the patient’s age, localization of the tumor, and neuroimaging results. This case showed a backward shift of the chiasma, which is observed in only 4.7% of craniopharyngioma, as well as normal endocrine findings. Endocrinological examination and an MRI evaluation of the chiasmal shift may be useful for discrimination. | 2022-12-03T17:37:40.570Z |

} | This paper seeks to estimate exchange rate pass-through in China and investigate its relationship with monetary policy. Linear and VAR models are applied to analyze robustness. The linear model shows that, over the long run, a 1% appreciation of NEER causes a decline in the CPI inflation rate of 0.132% and PPI inflation rate of 0.495%. The VAR model supports the results of the linear model, suggesting a fairly low CPI pass-through and relatively higher PPI pass-through. Furthermore, this paper finds that, with the fixed exchange rate regime, CPI pass-through remains higher. The exchange rate regimes influence on CPI pass through, combined with the fact that appreciation diminishes inflation, suggests that the Chinese government could pursue a more flexible exchange rate policy. In addition, reasons for low exchange rate pass-through for CPI are analyzed. The analysis considers price control, basket and weight of Chinese price indices, distribution cost, and imported and non-tradable share of inputs. | 2022-12-16T12:21:20.413Z |

This article overviews four major categories of telehealth technology based on patients' roles in self-management: surveillance, testing peripherals and messaging, decision support aids, and online support groups related to patients' subordinate, structured, collaborative, and autonomous roles, respectively. These various telehealth technologies should be selected on the basis of patients' care needs and preferences. Moreover, when they are integrated with other clinical information systems, case management practice can be better performed. However, the specific role functions and skill sets needed to be competent in telehealth environments have not yet been clearly identified. Considering role ambiguity and stress among telehealth clinicians, clarifying relevant roles is an urgent task. | 2022-12-18T09:17:00.173Z |

} | Employing nonlinear elements in photonic crystals (PCs) opens up lots of new design opportunities. In comparison to ordinary linear PC structures, using optically nonlinear elements in PCs leads to the observation of many interesting phenomena that can be utilized to design all-optical devices. Optical bistability in PCs is among the mentioned observations, which due to its many applications has attracted the researchers’ attention. Many optical devices such as limiters, switches, memories can be implemented when nonlinear elements are embedded in PCs. Kerr type nonlinearity is mostly used for this purpose. In this chapter we are going to discuss the benefits of using nonlinearity in photonic crystal devices. Since most of nonlinear optical devices are either based on directional couplers (DCs) or coupled cavity waveguides (CCWs), we have focused on these two groups to provide a better insight into their future prospects. | 2022-12-17T13:57:53.539Z |

} | An efficient enzymatic two-step cascade procedure has been devised for rapid access to diverse amino acids from N-hydroxymethyl-β-lactams; representative amino acids include the antifungal agent cispentacin, intermediates for the taxol side-chain, and assorted cathepsin inhibitors. When CAL-B-catalysed hydrolyses of racemic N-hydroxymethyl-β-lactams were performed with H2O (0.5 equiv.) in iPr2O at 60 °C, relatively quick (vs. non-activated counterparts) and enantioselective (E > 200) ring cleavage reactions took place. As the ring-opened amino acids formed, the hydroxymethyl group, as a traceless activating group, underwent spontaneous in situ degradation. Consequently, the desired β-amino acid and unreacted N-hydroxymethyl-β-lactam enantiomers (ee > 95 %) were formed. The formation of polymers, induced by liberation of formaldehyde, was successfully restricted by the addition of benzylamine as a capture agent, to the enzymatic reactions. An efficient enzymatic two-step cascade procedure was devised for CAL-B-catalysed hydrolysis of racemic N-hydroxymethyl-β-lactams. Conditions in which the hydroxymethyl group serves as a traceless activating group (E > 200), giving desired β-amino acid along with unreacted starting lactam enantiomers (ee > 95 %) were identified; polymerization was controlled by addition benzylamine addition.

} | Advanced polyolefins exhibit sophisticated molecular structures with unique processing and applications properties. One way of tailor-making novel polyolefin structures is through novel polymerization processes or modifying existing structures through functionalization or grafting. The latter approach is taken in the present work where novel grafted polyethylenes (HDPE-g-LDPE) were prepared. To elucidate the molecular heterogeneity of these novel materials in terms of branching and molar mass, a comprehensive multidimensional analytical approach was developed. Advanced analytical techniques such as CRYSTAF, DSC, HPLC, SEC and NMR were used for bulk sample analysis and first indications for the presence of non-grafted LDPE and HDPE along with the graft polymer HDPE-g-LDPE were obtained. For a more detailed study of the materials’ heterogeneity, the samples were fractionated by preparative TREF to obtain fractions which were further analyzed regarding branching, molar mass and crystallinity. Different components including the non-grafted LDPE, HDPE and the grafted HDPE-g-LDPE were identified by crystallization-based, spectroscopic and chromatographic methods. The compositions of the different TREF fractions were estimated and fractions were identified that predominantly consist of HDPE-g-LDPE. The bulk samples and their corresponding TREF fractions were analyzed by 2D-LC (HPLC × SEC) to provide comprehensive two-dimensional pictures demonstrating the relationship between molar mass and branching. | 2022-11-08T16:08:33.720Z |

Here we propose a technique to estimate the regularized depth from defocus using diffusion. The coefficient of the diffusion equation is modeled using a pair-wise Markov random field (MRF) ensuring spatial regularization to enhance the robustness of the depth estimated. This framework is solved efficiently using a graph-cuts based techniques. The MRF representation is enhanced by incorporating a smoothness prior that is obtained from a graph based segmentation of the input images. The method is demonstrated on a number of data sets and its performance is compared with state of the art techniques. | 2022-10-25T10:37:45.402Z |

} | In order to enhance the electrochromic performance of sol–gel derived WO3 coatings, especially the electrochemical cycling stability, a small amount of dopamine (DA) is introduced into a peroxotungstic acid (PTA) precursor sol to form complexes with tungsten on the surface of PTA colloidal nanoparticles. The DA molecules act as a precursor stabilizer, giving the sol a very long shelf life, which is crucial for practical applications, and also play the role of a structure-directing agent, providing a nanocrystal-embedded amorphous WO3 coating by annealing at 300 °C. Compared with the corresponding neat WO3 coating, the modified WO3 coating prepared from the complex sol gives much higher optical contrast, a faster switching speed and a higher coloration efficiency. It also shows excellent long-term cycling stability (maintaining a stable high contrast up to 35 000 cycles), which is far superior to not only the reference neat WO3 coating but also WO3 coatings prepared via other wet chemical routes. The excellent cycling stability may be attributed to the buffering effect of the nanocrystal-embedded amorphous regions, which accommodate the volume change of the nanocrystals induced by ion insertion/extraction. The uniform distribution of the nanometer-sized amorphous and crystal regions may help to reduce stress concentration and hence suppress erosion caused by local stress. | 2022-12-10T11:38:38.526Z |

} | Volatile organic compounds including benzene that are produced in industrial activities, especially those emitted from gas stations, can have undesirable effects on the environment and human health. TANKS 4.09 d software was used to calculate benzene emissions from gasoline storage tanks in gas stations throughout the 22 Districts in Tehran. Benzene emissions 1.5 m above the ground was modeled for a 12-month statistical period (2018) using AERMOD. Based on the results of emissions, the maps of benzene dispersion and comparison with the number of loading, storage capacity and numbers of storage tanks and active nozzles, In this study, it was identified that benzene emissions have increased due to lack of proportionality between gasoline storage capacity and demand for it and the concentration of gas stations at specific sites without observance of the suitable distance between them. The highest concentration of benzene emissions was recorded in Districts 4,2,15 and 1 (0.143, 0.128, 0.121, 0.118 gr/s respectively) and the lowest in Districts 17 and 14 (0.008, 0.03 gr/s respectively).In heavy traffic Districts, the number of loading and hence benzene emissions have increased due to the high demand for gasoline, the disproportionality between storage capacity and consumer demand for gasoline, and the small number of gas stations. In light traffic Districts, benzene emissions have increased because of the low demand for gasoline, the lack of proportionality between storage capacity and demand for gasoline, and the large number of gas stations that leads to gasoline storage in excess of the demand for it. | 2022-12-17T18:02:45.986Z |

} | This paper proposes a novel particle swarm optimization (PSO) algorithm based fuzzy logic controller (FLC) for improving the performance of automatic solid-state transfer switch (SSTS) with respect to transfer time. The proposed technique generates adaptive membership functions (MFs) of voltage error and rate of change of voltage error for input and output based on the fitness function formulated by the PSO. An optimal PSO-based FLC (PSOF) fitness function is further employed to tune and minimize the mean absolute error (MAE) to improve the performance of the load transfer in a short duration. Results obtained from the proposed PSOF are compared with those obtained with the conventional FLC to validate the developed controller. It is observed that the proposed PSOF optimized controller can transfer the load faster than the conventional FLC controller. The accuracy of the developed PSOF is illustrated and investigated via simulation tests for SSTS in the IEEE 9-bus system. It can be concluded that the PSOF controller is better than the only fuzzy controller in all tested cases in terms of transfer time. | 2022-12-11T00:02:37.793Z |

} | ABSTRACT Auditing firms tend to promote rule-bound orthodoxies about management based on the fiction that the world is more predictable than it is. Managers in INGOs find that long-term planning requires endless readjustment. This article explores what happens when these conflicting knowledge regimes clash during auditing. It draws on Bourdieu’s ideas to illuminate how different forms of social capital come into play in conflicting versions of management and control, whether centralised and prereflected or distributed and adaptive. In this case, a conflict during audit was resolved through negotiation and the establishment of alliances, showing how being audited requires complex political skills. | 2022-12-23T02:08:38.808Z |

} | Significance Megacities contribute significantly to national and global CO2 emissions and are an increasingly important element of emissions mitigation efforts. Atmospheric monitoring helps to characterize urban emissions, but CO2 measurements alone cannot distinguish between biogenic and fossil fuel contributions to observed CO2 enhancements. We use measurements of CO2 and the fossil fuel tracer 14CO2 to demonstrate that even for highly urbanized and arid environments such as Los Angeles, the managed urban biosphere contributes significantly to the local carbon budget. These findings highlight the need to understand and quantify urban biospheric CO2 in order to more accurately measure and track fossil fuel–CO2 emissions and the impact of urban greening campaigns, as needed to evaluate and optimize emissions mitigation strategies. Measurements of Δ14C and CO2 can cleanly separate biogenic and fossil contributions to CO2 enhancements above background. Our measurements of these tracers in air around Los Angeles in 2015 reveal high values of fossil CO2 and a significant and seasonally varying contribution of CO2 from the urban biosphere. The biogenic CO2 is composed of sources such as biofuel combustion and human metabolism and an urban biospheric component likely originating from urban vegetation, including turf and trees. The urban biospheric component is a source in winter and a sink in summer, with an estimated amplitude of 4.3 parts per million (ppm), equivalent to 33% of the observed annual mean fossil fuel contribution of 13 ppm. While the timing of the net carbon sink is out of phase with wintertime rainfall and the sink seasonality of Southern California Mediterranean ecosystems (which show maximum uptake in spring), it is in phase with the seasonal cycle of urban water usage, suggesting that irrigated urban vegetation drives the biospheric signal we observe. Although 2015 was very dry, the biospheric seasonality we observe is similar to the 2006–2015 mean derived from an independent Δ14C record in the Los Angeles area, indicating that 2015 biospheric exchange was not highly anomalous. The presence of a large and seasonally varying biospheric signal even in the relatively dry climate of Los Angeles implies that atmospheric estimates of fossil fuel–CO2 emissions in other, potentially wetter, urban areas will be biased in the absence of reliable methods to separate fossil and biogenic CO2. | 2022-12-26T15:31:21.151Z |

} | This paper deals with the simplified economic evaluation of the peak shaving by a battery-based energy storage system in plants with cyclic load profile (typically steel plants) and its own electrical energy source – typically the steam turbine. There are several possible motivations and/or benefits to be explored. The paper focuses on the optimal sizing of the turbine and BESS in relation to the total costs of investment and operation. There is proposed a methodology of integration into these plants. A control strategy of Battery Energy Storage System (BESS) operation is proposed. The impact is put on the inclusion of all economically important factors. Finally, the case study is defined and evaluated, based on the steel plant load diagram and other key factors. The technical-economic potential of this application is discussed in the conclusion. | 2022-11-18T00:05:28.674Z |

} | The purpose of this study was to examine how pre- and postmigration factors affect the psychological distress and adjustment for a community sample of Vietnamese refugees resettled in the United States. The sample included a substantial proportion of ex-political detainees who experienced a particularly large number of traumatic events prior to migration. Additionally, the study assessed postmigration experiences using multidimensional and bidirectional measures of acculturation to the Vietnamese and American cultures and measures of satisfaction with social support from like-ethnic and host culture network members. Psychological adjustment and distress were assessed with depression, anxiety, alienation, and life satisfaction. Findings show that premigration traumatic experiences predicted only measures of anxiety. The other measures of adjustment and distress were predicted by postmigration factors, including acculturation and social support. In sum, findings suggest that different psychological outcomes are predicted by different pre- and postmigration factors, suggesting that adjustment is a complex process that involves multiple indicators and dimensions. Significant differences were also found between ex-political detainees and other Vietnamese refugees suggesting the importance of considering their unique experience. | 2022-12-18T14:09:53.368Z |

} | Neoglycopolymers of polyacrylamide backbone conjugated with varying densities of Galα1−3Galβ1−4Glcβ trisaccharide epitopes (α-Gal epitopes) were designed and synthesized to study the inhibition of the binding of human natural anti-Gal antibodies to either α-Gal-containing glycoproteins or α-Gal antigens on the surface of mammalian cells. An inhibition ELISA using mouse laminin and a flow cytometry assay using pig kidney cells (PK15) were established to determine the binding affinity of the synthesized polymers. In comparison to the α-Gal monomer (Galα1−3Galβ1−4GlcNHAcβ), the α-Gal polymers dramatically enhanced the inhibition of human anti-Gal antibodies (IgG, IgM, and IgA) binding to mouse laminin or mammalian cells. Increases of 7.8 × 103- and 5.0 × 104 -fold in inhibitory potential of polymer 7C to IgA and IgM (with IC50s of 7.0 and 5.6 nM respectively) were observed over the monomer in inhibition ELISA.

The strong final-state interactions, especially the coupled-channel ($\pi\pi$ and $K\bar{K}$) final-state interaction in the $S$-wave are taken into account in a model-independent way using dispersion theory. It is found that the light-quark SU(3) octet state plays a significant role in these transitions, implying that the $Y(4260)$ contains a large light-quark component. Our findings suggest that the $Y(4260)$ is neither a hybrid nor a conventional charmonium state. Furthermore, through an analysis of the ratio of the light-quark SU(3) octet and singlet components, we show that the $Y(4260)$ does not behave like a pure $\bar D D_1$ hadronic molecule as well. | 2022-02-08T03:50:24.290Z |

} | Background Anti-nuclear antibodies (ANA) are found in patients with (non)-rheumatic diseases and in healthy controls, with 30% positives in the latter group.1 ANA testing is useful in diagnosing auto-immune diseases, especially in Systemic Lupus Erythematodus (SLE), Systemic Sclerosis (SSc), polymyositis (PM), dermatomyositis (DM), Mixed Connective Tissue Disorder (MCTD) and Sjögren Syndrome (SS).1 For the correct use of diagnostic tests knowledge about disease prevalence and test characteristics is essential. Many physicians find this difficult to apply, often leading to overuse of tests.2,3 Objectives To assess the characteristics of ANA testing in patients visiting the rheumatology outpatient clinic of the Sint Maartenskliniek, the Netherlands, before and after a targeted intervention. Methods The number, result and final diagnosis of all ANA tests done by rheumatologists working at the clinic between 1-1-2010 and 31-1-2012 (25 months) were compared with the ANA’s done after the intervention (1-7-2012 and 31-10-2012; 4 months). To make comparison possible the absolute ANA count was corrected for the number of new patients seen at the outpatient clinic in the same period. The intervention consisted of a one-hour, group wise training in which the results from the pre-intervention period were given together with general background information on the correct ANA use. Directly afterwards all doctors received individual information on their own ANA tests in comparison with their peers. Results In the pre-intervention period 2696 ANAs were requested by 14 rheumatologists in 2673 unique patients (mean age 53 ±15 years, 74% women); 62% were negative. The most frequent final diagnoses were undifferentiated artralgia/myalgia (20%), rheumatoid arthritis (19%) and fibromyalgia (8%); 7% had an ANA-associated disease (SLE, SSc, PM, DM, MCTD, SS). In the four months after the intervention 127 ANA’s were requested by the same rheumatologists in 125 unique patients (mean age 48 ±17 years, 81% women); 56% were negative. When corrected for number of new patients seen, on average 0.42 (SD ±0.15) ANA per new patient was done in the pre-intervention period and 0.15 (SD ±0.15) in the post-intervention period (p= 0.00), resulting in a decrease of 64% (figure 1). The distribution of the final diagnoses did not change. Image/graph Conclusions The finding that our single session intervention resulted in a sizable reduction in number of ANA’s requested, while inter-individual variation and final diagnoses remained unchanged, suggests that excessive usage was reduced without a reduction in appropriate use.

} | Background: To date, no study has focused on body composition characteristics and on parameters associated with skeletal muscle damage and renal function in runners participating in a 24-h winter race held under extremely cold environmental conditions (average temperature of -14.3°C). Methods: Anthropometric characteristics, plasma urea (PU), plasma creatinine (Pcr), creatine kinase (CK), plasma volume (PV) and total body water (TBW) were assessed pre- and post-race in 20 finishers (14 men and 6 women). Results: In male runners, body mass (BM) (p = 0.003) and body fat (BF) (p = 0.001) decreased [-1.1 kg (-1.4%) and -1.1 kg (-13.4%), respectively]; skeletal muscle mass (SM) and TBW remained stable (p > 0.05). In female runners, BF decreased (p = 0.036) [-1.3 kg (-7.8%)] while BM, SM and TBW remained stable (p > 0.05). The change (Δ) in BM was not related to Δ BF; however, Δ BM was related to Δ SM [r = 0.58, p = 0.007] and Δ TBW (r = 0.59, p = 0.007). Δ SM correlated with Δ TBW (r = 0.51, p = 0.021). Moreover, Δ BF was negatively associated with Δ SM (r = -0.65, p = 0.002). PV (p < 0.001), CK (p < 0.001), Pcr (p = 0.004) and PU (p < 0.001) increased and creatinine clearance (CrCl) decreased (p = 0.002). The decrease in BM was negatively related to the increase in CK (r = -0.71, p < 0.001). Δ Pcr was positively related to Δ PU (r = 0.64, p = 0.002). The decrease in CrCl was negatively associated with the increase in both PU (r = -0.72, p < 0.001) and CK (r = -0.48, p = 0.032). Conclusion: The 24-h running race under extremely cold conditions led to a significant BF decrease, whereas SM and TBW remained stable in both males and females. Nevertheless, the increase in CK, Pcr and PU was related to the damage of SM with transient impaired renal function. | 2022-02-09T02:24:20.629Z |

} | In recent years, the possibility for ac and dc transmission lines running parallel to each other, sharing the same right-of-way (ROW) or even the same tower has been increased. Design of such hybrid ac/dc networks requires a precise calculation of the electric field around and under them. This paper presents quantitative analysis of the electric field at 1 m height above ground surface for different hybrid ac/dc transmission lines. Lateral profiles for typical Egyptian 500, 220 and 132 kV after adding bipolar dc lines are presented. The paper also considers reconfiguration of a typical 220 kV Egyptian double-circuit ac transmission line, in which one of the circuits is converted into ±220 kV bipolar dc line. Different reconfiguration alternatives are studied to choose the optimum arrangement. The charge simulation method (CSM) employing the superposition principle is used to calculate the RMS value of the electric field generated by hybrid ac/dc lines at any point in the space. The RMS values of the field are determined directly without dividing the ac supply cycle into a sufficient number of subintervals as it has been done before. Satisfactory agreement with the results measured and calculated before by other techniques, for some typical ac/dc lines, has been obtained.

} | According to Friedrich Nietzsche, artists impose restrictions on themselves to encourage creativity and even have a way of “making things difficult” – imposing new constraints on themselves within which they have to dance. At least in the arts, it is difficulty rather than ease which promotes creativity in accordance with this view. This goes beyond the well-known idea of rules and other structures not only restricting but also enabling creativity; it also goes beyond insight into the creativity-enhancing effects of constraints, as recently emphasized in organization studies. Nietzsche adds three dimensions to this dialectic: time and the process of dancing inspired and encouraged by constraints; the opposition of old and new constraints; and the quality of intended, stimulating self-binding. We see this as an opportunity to explore the inspiring potential of Nietzsche’s piece about arts, “Dancing in chains”, when it comes to the different realm of creative practices and creativity in and of organizations. Such an exploration can obviously not aim to offer recipes of how to bring about valuable novelty, but simply intends to identify pertinent themes, issues and questions for organization studies – topics and aspects brought into a new or sharper light when looked at from Nietzsche’s perspective and that of some other philosophers, including Jon Elster’s analyses of constraints in general and of the complications of self-binding in order to promote creativity in particular. Also, we consider Míchel de Certeau’s “silent production” and Martha Feldman’s improvisational routines as being cases of “dancing in chains”. | 2022-12-08T17:21:38.574Z |

} | Background The species Salmonella enterica (S. enterica) includes many serovars that cause disease in avian and mammalian hosts. These serovars differ greatly in their host range and their degree of host adaptation. The host specificity of S. enterica serovars appears to be a complex phenomenon governed by multiple factors acting at different stages of the infection process, which makes identification of the cause/s of host specificity solely by experimental methods difficult. Methodology/Principal Findings In this study, we have employed a molecular evolution and phylogenetics based approach to identify genes that might play important roles in conferring host specificity to different serovars of S. enterica. These genes are ‘differentially evolved’ in different S. enterica serovars. This list of ‘differentially evolved’ genes includes genes that encode translocon proteins (SipD, SseC and SseD) of both Salmonella pathogenicity islands 1 and 2 encoded type three secretion systems, sptP, which encodes an effector protein that inhibits the mitogen-activated protein kinase pathway of the host cell, and genes which encode effector proteins (SseF and SifA) that are important in placing the Salmonella-containing vacuole in a juxtanuclear position. Conclusions/Significance Analysis of known functions of these ‘differentially evolved genes’ indicates that the products of these genes directly interact with the host cell and manipulate its functions and thereby confer host specificity, at least in part, to different serovars of S. enterica that are considered in this study. | 2022-12-19T12:09:45.799Z |

During the Trump administration, Sino-American relations have deteriorated to the point where the new consensus in the U.S. foreign policy establishment is that a new Cold War has begun between the U.S. and China. This article looks at the origins of the “first Cold War” for insight into how a second Cold War might be avoided. There is a danger of the Cold War turning hot because of power transition dynamics. This article also invokes the pre-1914 Anglo-German rivalry, and argues that if conflict is to be avoided, the U.S. must accommodate China's rise by yielding hegemony in East Asia and meeting China's status claim. | 2022-12-28T20:25:13.783Z |

} | The emergence of SARS‐CoV‐2 in late 2019 and human responses to the resulting COVID‐19 pandemic in early 2020 have rapidly changed many aspects of human behavior, including our interactions with wildlife. In this commentary, we identify challenges and opportunities at human–primate interfaces in light of COVID‐19, focusing on examples from Asia, and make recommendations for researchers working with wild primates to reduce zoonosis risk and leverage research opportunities. First, we briefly review the evidence for zoonotic origins of SARS‐CoV‐2 and discuss risks of zoonosis at the human–primate interface. We then identify challenges that the pandemic has caused for primates, including reduced nutrition, increased intraspecific competition, and increased poaching risk, as well as challenges facing primatologists, including lost research opportunities. Subsequently, we highlight opportunities arising from pandemic‐related lockdowns and public health messaging, including opportunities to reduce the intensity of problematic human–primate interfaces, opportunities to reduce the risk of zoonosis between humans and primates, opportunities to reduce legal and illegal trade in primates, new opportunities for research on human–primate interfaces, and opportunities for community education. Finally, we recommend specific actions that primatologists should take to reduce contact and aggression between humans and primates, to reduce demand for primates as pets, to reduce risks of zoonosis in the context of field research, and to improve understanding of human–primate interfaces. Reducing the risk of zoonosis and promoting the well‐being of humans and primates at our interfaces will require substantial changes from “business as usual.” We encourage primatologists to help lead the way. | 2022-12-30T18:30:45.786Z |

} | I The Oxford Handbook of Political Theory is one of a series of handbooks on political science published by Oxford – the others being: ‘Contextual Political Analysis’ and ‘Public Policy’ Political Institutions Political Behavior Comparative Politics Law and Politics Political Economy International Relations Political Methodology Its range is very wide and certainly – as the table of contents attests to – goes beyond what has usually been conceived of as political theory. The contents are divided into 11 parts – ‘Introduction’, ‘Contemporary Currents’, ‘The Legacy of the Past’, ‘Political Theory in the World’, ‘State and People’, ‘Justice, Equality and Freedom’, ‘Pluralism, Multiculturalism, and Nationalism’, ‘Claims in a Global Context’, ‘The Body Politic’, ‘Testing the Boundaries’ and ‘Old and New’ – and 46 chapters. The chapters do indeed attest to the very heterogeneous and diversified thematic approach to political theory, and the geographical spread thereof, including for instance chapters on Islamic and Confucian theories and on the European Union – as well as a rather original chapter on American exceptionalism from the point of view of the American political self-conception and not, as in the work of S.M. Lipset or Daniel Bell, from the point of view of the non-development of socialism in the US or, as has been presented by Luis Hartz, from the point of view of the distinctiveness of American liberalism. Needless to say, one can find also topics which have not been taken up in separate chapters, such as for instance war or Empires – the references to the latter being closely connected to post-colonial discussion – or terrorism which is not to be found in the index and the discussions thereof are dispersed throughout different chapters. But such a situation is in a sense unavoidable – not all the topics which could bear in some way on political theory as it is conceived here could possibly be included. | 2022-12-23T16:17:20.888Z |

} | The intra-operative diagnosis of syndesmotic ligament rupture is problematic. Neither plain radiography1 or clinical testing is completely reliable.2,3
As the authors point out, fibular translation in the coronal plane correlates poorly with diastasis when using the hook test. Candal-Couto et al.4 demonstrated that translation in the sagittal plane was more significant than movement in the coronal plane after sequential division of the three syndesmotic ligaments in the cadaveric model (8.8 mm vs 1.5 mm). This suggests that intra-operative anteroposterior stressing rather than mediolateral stressing with the hook is a more sensitive test of syndesmotic failure. Why then do the authors advocate testing their technique in the coronal plane?
A further point of note is that this technique of pushing the tibia medially away from the fibula along the 3.5-mm tap will rely upon the patient having sufficient bone quality. In the osteoporotic patient, the tap may subside into the lateral cortex of the tibia and/or lose grip in the fibula, thus preventing analysis of the syndesmosis.
If one wished to stress the syndesmosis in the sagittal plane with this technique, movement would be limited (and the surgeon falsely re-assured) by contact with the tip of the 3.5-mm tap against posterior aspect of the anterior tibial tubercle. Perhaps if the tap was inserted flush with the medial cortex of the fibula then stressed in the sagittal plane, the technique would be more reliable? | 2022-02-12T04:19:44.753Z |

} | An elicitor has been isolated from Macrophomina phaseolina, the root rot and leaf blight pathogen of greengram. Suspension-cultured cells of greengram were established which responded to the fungal elicitor. When greengram leaves were inoculated with M. phaseolina two new peroxidases appeared. Similarly, two new peroxidases could be detected in suspension-cultured greengram cells when treated with the fungal elicitor. These peroxidases were purified by column chromatography and their molecular masses were 27 and 38 kDa. The new peroxidases detected in both leaves and cultured cells appear to be similar with the same molecular weights. | 2022-03-06T02:59:27.249Z |

} | Background Bilateral proprioception deficits were reported in stroke survivors. However, whether bilateral proprioception deficits exist in the ankle joint after stroke was unclear. Ankle proprioception is a significant predictor of balance dysfunction after stroke, and previous studies to date are lacking appropriate evaluation methods. Objectives We want to determine whether the active movement extent discrimination apparatus (AMEDA) is a reliable tool for assessing ankle proprioceptive acuity in stroke survivors and the presence of deficits in ankle proprioception on the affected and unaffected sides in patients after stroke. Methods Bilateral ankle proprioception was assessed in 20 stroke patients and 20 age-matched healthy controls using AMEDA. Test-retest reliability was assessed using the intraclass correlation coefficient (ICC). Results The ICC in the affected and unaffected sides was 0.713 and 0.74, respectively. Analysis of variance revealed significant deficits in ankle proprioception in subacute stroke survivors vs. healthy controls (F = 2.719, p = 0.045). However, there were no significant differences in proprioception acuity scores between the affected and unaffected sides in patients after stroke (F = 1.14, p = 0.331). Conclusions Stroke survivors had bilateral deficits in ankle proprioceptive acuity during active movements compared with age-matched healthy controls, underscoring the need to evaluate these deficits on both sides of the body and develop effective sensorimotor rehabilitation methods for this patient population. The AMEDA can reliably determine bilateral ankle proprioceptive acuity in stroke survivors. | 2022-09-09T05:10:44.443Z |

} | Studies on the ultraviolet ray absorption in the aqueous humour of rabbit, cat, monkey, guinea pig, and rat showed marked species differences. In the rabbit aqueous the ascorbic acid, the proteins, and some amino acids (tyrosine, phenylalanine, cystine, and tryptophane) are together responsible for the total absorption, and a very great part of it refers to the ascorbic acid content. Accordingly, species with significant amounts of ascorbic acid in the aqueous (monkey, rabbit, guinea pig) have a greater absorption capacity towards ultraviolet radiation than species (cat, rat) lacking this substance. This effect of the ascorbic acid may contribute in protecting the lens against the most biotoxic ultraviolet rays. It seems that the ascorbic acid concentration is highest in the aqueous of typical day animals and lowest in species being active in the dark, indicating a correlation between the aqueous' ascorbic acid level and the quantity of incident light on the eye. The possible significance of changed aqueous ultraviolet ray absorption in the pathogenesis of human cataract development is discussed. | 2022-09-11T23:24:28.977Z |
