['Detecting and understanding extragalactic Lyman [alpha] emission using 3D spectroscopy']
['n this thesis we use integral-field spectroscopy to detect and understand of Lyman α (Lyα) emission from high-redshift galaxies. Intrinsically the Lyα emission at λ = 1216 Å is the strongest recombination line from galaxies. It arises from the 2p → 1s transition in hydrogen. In star-forming galaxies the line is powered by ionisation of the interstellar gas by hot O- and B- stars. Galaxies with star-formation rates of 1 - 10 Msol/year are expected to have Lyα luminosities of 42 dex - 43 dex (erg/s), corresponding to fluxes ~ -17 dex - -18 dex (erg/s/cm²) at redshifts z~3, where Lyα is easily accessible with ground-based telescopes. However, star-forming galaxies do not show these expected Lyα fluxes. Primarily this is a consequence of the high-absorption cross-section of neutral hydrogen for Lyα photons σ ~ -14 dex (cm²). Therefore, in typical interstellar environments Lyα photons have to undergo a complex radiative transfer. The exact conditions under which Lyα photons can escape a galaxy are poorly understood. ...']

A particular emphasis is given on the problem of symbol encodings: Often there are multiple or even an unlimited number of possibilities to encode information in the phase space of dynamical systems, e.g. spike frequencies or population coding in neural networks.

['Mechanical characterisation and constitutive modelling of wrought magnesium sheets exhibiting tension-compression asymmetry']
[['Wrought magnesium alloys have emerged as promising candidates for highly loaded structural components in the automobile industry recently, due to their high specific strength and low density. In this work, two aspects of wrought magnesium alloys are studied experimentally and computationally: the mechanism-based modelling of plastic deformation and the crashworthiness assessment of simple structures. A constitutive model was developed to capture the plastic behaviour of wrought magnesium sheets under monotonic loading. Wrought magnesium sheets exhibit a strong and evolving tension compression asymmetry in terms of flow stress and r-value (strain anisotropy parameter). A yield function originally proposed by Cazacu, Plunkett and Barlat in 2006 was extended by introducing a new parameter depending on the plastic multiplier to describe this tension-compression asymmetry and its evolution. The model was applied to two different magnesium wrought alloys, AZ31 (Mg+3%Al+1%Zn) and ZE10 (Mg+1%Zn+0.3%Ce), each produced as rolled sheet and as extruded profile. A series of mechanical tests including uniaxial tensile and compression tests along different orientations, through thickness compression tests, shear tests, and notched bar tests was conducted for characterising the mechanical behaviour under various stress states. Experimental results confirm significantly different plastic deformation behaviour of the two alloys, which were resulted from their respective initial textures. For calibration of the material model, identification of material parameters was accomplished with the experimental data based on an error minimisation scheme. The computational results show that the proposed model captures the tension- compression asymmetry of both alloys. The calibrated model was finally applied to a pure bending simulation. The good agreement between the simulated and the semi-analytically calculated bending moment-curvature diagram demonstrates the predictive capability of the present model for the considered magnesium alloys. Experimental study and numerical simulations were conducted to investigate the plastic buckling and crush behaviour of structural components with hollow rectangular profiles fabricated from the two magnesium alloys. The used modelling approach is justified by balancing achievable accuracy and computational efforts. The performance of the components made by magnesium alloys was evaluated in term of the dissipated specific energy in the crush tests and compared with respective aluminium components. It is revealed that the observed high dissipation of magnesium alloys during crushing is related to the work hardening behaviour in compression.', 'Magnesiumlegierungen sind heutzutage aufgrund der hohen spezifischen Festigkeit und geringen Dichte aussichtsreiche Kandidaten für hochbelastete Strukturbauteile in der Automobilindustrie. In dieser Arbeit werden zwei Aspekte der Eigenschaften von Magnesiumlegierungen werden in dieser Arbeit experimentell und numerisch untersucht: die Mechanismus-basierte Modellierung der plastischen Verformung und die Beurteilung der Kollisionssicherheit von einfachen Strukturen. Zunächst wird Ein Konstitutivmodell zur Beschreibung des mechanischen Verhaltens von Magnesiumblechen unter monotoner Belastung entwickelt. Magnesiumbleche zeigen eine starke und sich mit der Verformung entwickelnde Zug-Druck-Asymmetrie in der Fließspannung und dem R-Wert (Dehnungsanisotropie-Parameter). Eine von Cazacu, Plunkett und Barlat in 2006 vorgeschlagene Fließfunktion wird durch die Einführung der Abhängigkeit eines Parameters vom plastischen Multiplikator zur Beschreibung der Zug-Druck-Asymmetrie und ihrer Evolution erweitert. Das Modell wird auf zwei unterschiedliche Magnesiumlegierungen angewendet: AZ31 (Mg+3%Al+1%Zn) und ZE10 (Mg+1%Zn+0.3%Ce), die jeweils als gewalztes Blech und als extrudiertes Profil hergestellt wurden. Eine Reihe von mechanischen Versuchen wird zur Charakterisierung der mechanischen Eigenschaften unter verschiedenen Spannungszuständen durchgeführt, einschließlich einachsiger Zug- und Druckversuche mit unterschiedlichen Orientierungen, Kompressions-, Scher- und Kerbversuche. Die Versuchsergebnisse zeigen, dass die beiden Magnesiumlegierungen sehr unterschiedliches plastisches Verformungsverhalten aufweisen, das von den jeweiligen Anfangstexturen erklärt wird. Für die Kalibrierung der Parameter des Materialmodells wird ein Fehlerminimierungsschema verwendet. Das kalibrierte Modell erfasst die Zug-Druck-Asymmetrie beider Legierungen. Schließlich wird das Modell in einer reinen Biegesimulation eingesetzt. Die Übereinstimmung zwischen dem simulierte und dem semi-analytisch berechneten Biegemoment-Krümmung Diagramm zeigt die Vorhersagefähigkeit des Modells für die beiden betrachteten Magnesiumlegierungen. Experimentelle Untersuchungen und numerische Simulationen werden zur Voraussage und Beurteilung des plastischen Beulens und des Aufprallverhaltens von rechteckigen Hohlprofilen durchgeführt, die aus den beiden Magnesiumlegierungen hergestellt sind. Der angewandte Modellierungsansatz berücksichtigt den Kompromiss zwischen erreichbarer Genauigkeit und benötigtem Rechenaufwand. Die Leistungsfähigkeit der Bauteile wurde anhand der spezifischen dissipierten Energie ausgewertet und mit entsprechenden Aluminiumbauteilen verglichen. Es zeigt sich, dass die beobachtete hohe Dissipation der Bauteile aus den Magnesiumlegierungen während des Aufpralls durch das Verfestigungsverhalten unter Druck verursacht wird.']]

['When the Greeks and surviving Armenians of present-day Turkey were forced to leave their homeland in 1922, the movable and immovable property they had to leave behind became known as „abandoned property“(emval-i metruke). In theory, this legal term implied that the absent owners continued to enjoy their property rights and were represented by the state.

['Chitosans are a diverse group of biopolymers, which are widely used in different fields of application for years. They are appreciated and used especially because of their antimicrobial effects combined with their biocompatible properties. However, details of the correlation between their physical-chemical characteristics and biological effects (e.g. antimicrobial effect) have not been fully understood yet. In the following thesis the antimicrobial properties were examined with mold fungi as well as with gram-positive and gram-negative bacteria. Furthermore, the biocompatibility was proven with a plant assay and the physical-chemical properties of chitosan were systematically investigated. The results of the investigations on mold fungi and bacteria allow the conclusion that chitosan has no antifungal capacities. Furthermore the mold fungi are able to use the chitosan as carbon resource. Certainly, chitosans operated as an inhibitor to the group of bacteria. They acted biostatical and bactericide, which led to a structural membrane damage of E. coli. However, there was no indication of a different effect on gram-positive bacteria compared to gram-negative bacteria. The effect of chitosans is presumably more affected by bacteria and their adaptation to the environment rather than by the composition of the membrane structure. It was shown that the marine gram-negative bacteria V. fischeri was less affected in the occurrence of luminescent than the bacteria E. coli (gram-negative) and B. subtilis (gram-positive) in their dehydrogenase activity. The biocompatibility is guaranteed unrestricted as long as the pH is neutral to alkaline. Chitosans will form micelles or aggregates under these pH conditions, which significantly reduces their bioavailability. Effects in eukaryotic test systems under acetic pH conditions demonstrated, that the chitosan significantly disturbed the growth of the plant L. minor. Additionally, no growth recovery was observed even several weeks after the treatment. No influence of the molecular weight of the Chitosans on inhibition effects could be found for the correlation of the physical-chemical properties with all EC values over all experiments. On the other hand it could be shown that the degree of acetylation (and additionally combined with the amount of acetylated units) and the pattern of acetylation might influence the impact of chitosan on biological effects. A low degree of acetylation or a low-numbered pattern of acetylation inhibited the growth of bacteria most clearly, whereas a high degree of acetylation or a high-numbered pattern of acetylation inhibited the growth of L. minor most effectively. Complete biocompatibility can probably be achieved by adaption of these characteristics of chitosan.']

We show that the transfer operator has an infinitely countable set of polynomial eigenfunctions. These eigenfunctions can be regarded as generalized Bernoulli polynomials. The polynomial eigenfuctions define a polynomial approximation of the self-similar measure. We also study the moments of the self-similar measure and give recursions for computing them. Further, we develop a numerical method based on Markov chains to study the spectrum of the Hutchinson and transfer operators. This method provides numerical approximations of the invariant measure for which we give error bounds in terms of the Wasserstein-distance.

We study the transfer operator (which acts on the space of continuous functions on the self-similar set) and the Hutchinson operator (which acts on the space of Borel regular measures on the self-similar set). We show that the transfer operator has an infinitely countable set of polynomial eigenfunctions. These eigenfunctions can be regarded as generalized Bernoulli polynomials. The polynomial eigenfuctions define a polynomial approximation of the self-similar measure. We also study the moments of the self-similar measure and give recursions for computing them. Further, we develop a numerical method based on Markov chains to study the spectrum of the Hutchinson and transfer operators. This method provides numerical approximations of the invariant measure for which we give error bounds in terms of the Wasserstein-distance. The standard example in this thesis is the parametric family of Bernoulli convolutions.']] ### GND ID: ['gnd:36158-6', 'gnd:4141470-6', 'gnd:4145587-3', 'gnd:4343626-2', 'gnd:4352361-4', 'gnd:4846596-3', 'https://www.tib.eu/de/suchen/id/TIBKAT%3A885211707'] ### GND class: ['Ernst-Moritz-Arndt-Universität Greifswald', 'Faltung (Mathematik)', 'Binomialverteilung', 'Iteriertes Funktionensystem', 'Invariantes Maß', 'Transferoperator'] <|eot_id|>

['Gerichtete MWCNT/ Polypyrrol Hybride als Material für anisotrope Aktuatoren']
[['The present work describes the manufacturing of vertically and horizontally aligned Multi Walled Carbon Nanotube (MWCNT)/ Polypyrrole Hybrids and their direction dependent behavior when actuated. In these hybrids, the Polypyrrole component is responsible for the actuation; already at very low potential differences and currents the polymer can be oxidized and reduced reversibly. This redox-procedure is accompanied by a diffusion of solvated ions from the surrounding electrolyte and therefore, the volume of the polymer swells or contracts. Because Polypyrrole is active under physiological conditions, a possible application for such Hybrids would be to use them as micro-actuators for implantable micro-dosing systems, which has a working principle very similar to that of a compressor. In the described Hybrids, the MWCNTs take over the role as an incorporated electrode and ensure an even distribution of charges. At the same time, they induce direction dependent actuation (or anisotropy in actuation) owing to their high stiffness along their main orientation direction and nanostructured shape. The contraction and elongation in the direction parallel to the main MWCNT orientation is almost completely deterred. As a starting material for the manufacturing of the Hybrids, vertically aligned MWCNTs produced via gas flow CVD processes are used. Through a mechanical process, these vertically oriented MWCNTs can be transformed into horizontally aligned Buckypapers by densification. In a subsequent electrochemical polymerization process, each of these individual MWCNTs is coated with a very thin layer (~20 nm) of Polypyrrole.

["The Atlantic Slave Trade from West Central Africa traces for the first time the origins of slaves leaving West Central Africa at the peak period of the transatlantic slave trade. West Central Africa was one of the principal sources of slaves for the Americas. During the nineteenth century, the importance of the region as a supplier of slaves increased as a result of the suppression of the trade north of the Equator. Although some nations retreated from the business early in that century, others remained active, expanding their activities along the coast of West Central Africa. Some scholars of the slave trade claim that a quest for political power motivated Africans to sell one another into the transatlantic commerce as prisoners of war.

['Transcriptome dynamics to unravel PC12 cell fate decisions']
['Abstract: The PC12 cell line is a well-established cell model system for analysing cell fate decisionmaking processes. When stimulated with the growth factor EGF the cells proliferate increasingly, when stimulated with the nerve growth factor NGF the cells differentiate into sympathetic-like neurons. Both processes are regulated via the ERK/MAPK pathway. In this context, signal duration of activated ERK seems to be the key mechanism for the emergence of the distinct cell fates. Whereas NGF stimulation results in sustained ERK activation and neuronal differentiation of the cell line, EGF stimulation activates ERK transiently and results in enhanced cell proliferation. How the temporal dynamics of ERK signalling are encoded and translated in order to specify cell fates has not been fully understood yet. <br>This thesis is the first comparison of the EGF and NGF induced transcriptome of PC12 cells on a time scale of 24 hours with high sample density. It was shown that the EGF and NGF stimulus activate a very similar set of genes, which initiates and modulates the cell fate decision. These genes’ expression dynamics, however, were different depending on the stimulus used: EGF stimulation induced a short impulse-like gene expression pattern, whereas NGF stimulation resulted in a long-sustained response. In line with previous studies it was demonstrated, that immediate early genes such as Egr1, Fos and Junb show an increased stability in the case of NGF stimulation. It was shown, that this is most likely due to a delayed negative transcriptional feedback via Fosl1, Atf3, Maff, Klf2 und Zfp36l2. Moreover it was demonstrated, that both cell fates, proliferation as well as differentiation, are not solely dependent on the ERK/MAPK pathway. Within the first hour after stimulation with EGF cross-talk between the MAPK and PI3K pathways seems necessary in order to induce enhanced cell proliferation. After stimulation with NGF a more complex and sequential activation of different pathways was identified. In this context the activation of the Il6 pathway and the uPA/uPAR complex seems to be of special importance.

Document ### Title: ['Transcriptome dynamics to unravel PC12 cell fate decisions'] ### Abstract: ['Abstract: The PC12 cell line is a well-established cell model system for analysing cell fate decisionmaking processes. When stimulated with the growth factor EGF the cells proliferate increasingly, when stimulated with the nerve growth factor NGF the cells differentiate into sympathetic-like neurons. Both processes are regulated via the ERK/MAPK pathway. In this context, signal duration of activated ERK seems to be the key mechanism for the emergence of the distinct cell fates. Whereas NGF stimulation results in sustained ERK activation and neuronal differentiation of the cell line, EGF stimulation activates ERK transiently and results in enhanced cell proliferation. How the temporal dynamics of ERK signalling are encoded and translated in order to specify cell fates has not been fully understood yet. <br>This thesis is the first comparison of the EGF and NGF induced transcriptome of PC12 cells on a time scale of 24 hours with high sample density. It was shown that the EGF and NGF stimulus activate a very similar set of genes, which initiates and modulates the cell fate decision. These genes’ expression dynamics, however, were different depending on the stimulus used: EGF stimulation induced a short impulse-like gene expression pattern, whereas NGF stimulation resulted in a long-sustained response. In line with previous studies it was demonstrated, that immediate early genes such as Egr1, Fos and Junb show an increased stability in the case of NGF stimulation. It was shown, that this is most likely due to a delayed negative transcriptional feedback via Fosl1, Atf3, Maff, Klf2 und Zfp36l2. Moreover it was demonstrated, that both cell fates, proliferation as well as differentiation, are not solely dependent on the ERK/MAPK pathway. Within the first hour after stimulation with EGF cross-talk between the MAPK and PI3K pathways seems necessary in order to induce enhanced cell proliferation. After stimulation with NGF a more complex and sequential activation of different pathways was identified. In this context the activation of the Il6 pathway and the uPA/uPAR complex seems to be of special importance. The activation of these two pathways was exclusively seen after NGF-stimulation, which encourages further research to gain a deeper understanding of their function in the process of neuronal differentiation. Additionally, Dusp6 was identified as a potentially important modulator of the PC12 cell fate. In summary, this thesis analyses and compares the EGF and NG ...'] ### GND ID: ['gnd:1130605205', 'gnd:4171485-4', 'gnd:4271160-5', 'gnd:4775955-0', 'https://www.tib.eu/de/suchen/id/TIBKAT%3A88781347X'] ### GND class: ['Offermann, Barbara', 'Nervenwachstumsfaktor', 'Epidermaler Wachstumsfaktor', 'Transkriptom'] <|eot_id|>

['Ultrashort pulse induced nanostructures in transparent materials']
['Glass fascinates mankind since its first discovery about 30 thousand years ago. Besides the challenging conditions for fabricating glasses with homogeneous properties the technological prospects for precise machining were first developed in the last millennium. While core areas of glass processing were dominated by well-established mechanical techniques such as scribing, grinding, sawing and polishing the technological progress and ongoing miniaturization demanded alternative processing tools. Within the end of the 20th century the development of ultrashort pulse laser systems paved the way for precise and cost-efficient solutions for materials processing in key technologies such as computer chips, medical surgery or in the field of automotive. Even more, the short pulse duration represents the key to locally process transparent materials within the bulk to induce modifications with feature sizes smaller than the wavelength of light [1, 2]. When focusing ultrashort laser pulses in the bulk of glass nonlinear absorption leads to extreme non-equilibrium states within a confined volume mediating the localized deposition of the laser pulse energy. Fused silica turned out as versatile platform to study the laser-induced modifications. Typically three different kinds are distinguished. First, isotropic refractive index changes allow for inscribing waveguides [3, 4] that may serve to realize complex photonic networks [5, 6]. Second, a confined micro-explosion within the focal volume may leave a region devoid of any material [7, 8] that can be used for data storage [9] or microfluidic purposes [10]. Finally, one of the key findings of laser materials processing is the local inscription of strong birefringence due to a sub-wavelength grating structure within an otherwise isotropic host material [11, 12].']

['Trapped atomic ions for fundamental studies of closed and open quantum systems']
['Abstract: Any realistic quantum system interacts with its environment. While this leads to inadvertent perturbations in many applications, this interaction lies at the heart of countless interesting phenomena. Trapped atomic ions are well suited to study quantum dynamics on a fundamental level. They feature extensive control in preparation, coherent manipulation, and detection of internal (electronic) and external (motional) degrees of freedom. In addition, they allow for a remarkable degree of isolation from their surroundings. In this thesis, we use a trapped-ion setup to experimentally compose and study specific open and closed quantum systems. Starting with a single magnesium ion, we introduce an incoherent interaction with a large environment to tailor an open quantum system. We demonstrate that the fast and substantial impact of decoherence can be exploited to devise a high-precision spectroscopy method with sensitivity to single photons. We measure one-, two-, and three-photon transitions in 25Mg+ with a relative frequency uncertainty below 5 x 10^(-9), making our results relevant for the interpretation of astrophysical data in the search of spatial and temporal variations of the fine structure constant. Further, in a bottom up approach, we use a hybrid ion crystal of magnesium isotopes to construct a nearly closed quantum system atom by atom. We choose a subsystem of interest and realize a tunable degree of isolation from the rest of the closed system to study properties of the (open) subsystem. By the deliberate disregard of correlations and coherences through the measurement of subsystem observables, we find evidence of equilibration and thermalization, despite the underlying unitary dynamics of the total system. We study their dependence on the engineered size of the environment and the controlled strength of the interaction, where the coherent evolution explores Hilbert space dimensions exceeding 10^6. Our time-resolved measurements demonstrate finite-size effects as well as the transition to mesoscopic system dynamics and highlight the importance of associated time scales. Our setup can be extended by addition of spins and bosonic degrees of freedom, preparation of arbitrary internal and external states and initial correlations, and full state tomography. This paves the way, both for the study of open and closed system dynamics and their properties, and for an analogue quantum simulator for various model systems']

We study their dependence on the engineered size of the environment and the controlled strength of the interaction, where the coherent evolution explores Hilbert space dimensions exceeding 10^6. Our time-resolved measurements demonstrate finite-size effects as well as the transition to mesoscopic system dynamics and highlight the importance of associated time scales. Our setup can be extended by addition of spins and bosonic degrees of freedom, preparation of arbitrary internal and external states and initial correlations, and full state tomography. This paves the way, both for the study of open and closed system dynamics and their properties, and for an analogue quantum simulator for various model systems'] ### GND ID: ['gnd:113155793X', 'gnd:4246725-1', 'gnd:4297078-7', 'gnd:4300046-0', 'https://www.tib.eu/de/suchen/id/TIBKAT%3A889458774'] ### GND class: ['Clos, Govinda', 'Ionenfalle', 'Magnesiumion', 'Quantenmechanisches System'] <|eot_id|>

['Diffuse radio emission at low frequencies in merging galaxy clusters']
['Extended diffuse radio features so-called radio halos radio relics and radio mini-halos are found in about 100 galaxy clusters. The radio emission originates from relativistic electrons suffering synchrotron losses in the magnetized intra-cluster medium. Little is known about the mechanisms how electrons in the intra-cluster medium get accelerated to relativistic energies. Observations at low radio frequencies permit the analysis of the distribution of the population of aged relativistic electrons. In this work we analyzed in the context of the WSRT 346 MHz Legacy Survey ten galaxy clusters with already known diffuse radio sources and yet unclassified sources. We confirm radio relics in three clusters radio halos in five clusters and classified a radio relic candidate as a radio galaxy. Furthermore we revealed radio features with remarkable morphology in the galaxy cluster Abell 2069. Abell 2069 is a complex merging galaxy cluster which shows two distinct X-ray peaks. The main cluster component evidently possesses a radio halo and the subcomponent exhibits ultra-steep spectrum diffuse radio emission of uncertain nature. We conducted follow-up observations on Abell 2069 with LOFAR in the frequency range from 120 to 180 MHz. We complemented our investigation of Abell 2069 with GMRT observations at 322 MHz and 608 MHz as well as with archival Chandra X-ray data. Our analysis confirms the presence of a radio halo in the main cluster component. Furthermore we classify the diffuse radio emission in the subcluster as radio mini-halo. We detected signatures of fossil plasma ejected during a former active phase of an Active Galactic Nuclei in the subcluster. A cold front in the subcomponent suggests the presence of internal gas sloshing which could have induced bulk motions and turbulence in the subcluster. Both mechanisms together may have redistributed and re-accelerated the fossil plasma and caused the diffuse radio emission.']

['Transiting Sub-stellar companions on intermediate-mass stars']
['The aim of the project is to evaluate the predictions from theories of planet formation by determining the absolute frequency of close-in planets of intermediate-mass stars (IMSs). The detection of close-in planets of IMSs can put constraints to the theories of planet formation. First, it is known from infrared observations that the lifetimes of protoplanetary discs of IMSs are half as long as those of solar-mass stars. Second, radial velocity surveys of evolved IMSs show that the frequency of planets at distances larger than 5 AU is higher in comparison to solar-mass stars. However, not much is known about the frequency of close-in planets. An important key to constrain processes of planet formation and evolution is, thus, answering the question: “Is the frequency higher for close-in planets of IMSs than for solar-mass stars?” The transit method is best suited to find such planets. First, it is not affected by the fast rotation of these stars and secondly, it favours the detection of close-in planets. I used the CoRoT database to survey all IMSs observed with this instrument. In contrast to ground- based surveys, the precision of CoRoT allows the detection of all Jupiter-sized transiting objects orbiting IMSs. I first determined the mass-distribution of the stars in the sample. Second I found 14 transit candidates of IMSs in the CoRoT survey and observed them spectroscopically to determine their masses. In result, I detected one planet as well as two very young brown dwarfs with large radii of IMSs by this survey. Among them, the first transiting brown dwarf of a B-type star. The frequency for close-in planets of IMSs derived from this survey is 0.11 ± 0.04 %. This means that close-in sub-stellar companions of IMSs are rare. In the context of disc-migration, this surprising result can be explained by the lifetime of the protostellar discs of IMSs. It is apparently long enough for the planets to form, but on average too short for them to migrate inwards.']

['Time series analysis of high resolution remote sensing data to assess degradation of vegetation cover of the island of Socotra (Yemen)']
['The island of Socotra has long been in geographical isolation, hence nearly 30% of the plant species are believed to be endemic to the island. Until the end of 20th century there was only very little and incomplete information and literature about the vegetation on the island. This isolation broke down in 1990 with the country unification in which then the island received much attention. Subsequently the scientific knowledge of the local flora slowly increased, but many of plant species are now reported to be confined into small populations, hence being particularly vulnerable to habitat loss, overgrazing, as well as urban expansion. 1. The overall objective of this research attempted to assess and examine the trends of vegetation changes since 1972 to 2010 with the use of Landsat MSS, TM and ETM+ images and to investigate the related driving factors, such as rainfall, grazing pressure changes and underlying spatial variability of the landscape. This is to answer the overall question: Is there a trend in biomass, cover and species composition on Socotra Island over the last 40 years? If so, is that trend associated with the rainfall patterns? What are the drivers behind the vegetation change? And then how can we define changes in patterns or changes in this study area? 2. From a methodological point of view, our approach of systematically using remote sensing technology data proved scientifically an applicable tool to improve our understanding of the spatial complexity and heterogeneity of the vegetation cover as well as to provide a conceptual method with specific data for monitoring the changes over this time period. Our data obtained from these different Landsat sensors during the study period were - after many sophisticated processing steps - essentially able to provide time series information for Normalized Difference Vegetation Index (NDVI) data and to assess the long term trend in vegetation cover in the island. 3. Moreover, our approach combining supervised maximum-likelihood and unsupervised classification with the pre- and the post-classification approaches besides the knowledge based classification was table to provide sufficient results to distinguish and to map nine (9) terrestrial vegetation cover classes. The overall accuracy (compared with ground truth data) was about 91%, 77%, 70% and 72% for the images 2005, 1994, 1984 and 1972 respectively. Consecutively, the GIS analysis allowed estimates of highly valuable information as absolute areas and relative coverage of particular vegetation classes over the island with their spatial distribution and also their ecological requirements. Analysis of climatic conditions and NDVI 4. As a results of the complex topography of the study area and the wide climate range, with the guidance of prior knowledge of functional relationships between site parameters, ecosystem and the specific form of biological production, our work resulted in a division of the entire area into six variously sized ecosystem units, which were enough to properly depict the spatial heterogeneity of the rainfall and vegetation and to assist reflecting the influence and reaction between environmental parameters as well as it might have significance both for development of resources and for conservation of environment.']

['Propagation of partially coherent light in optical systems']
['There are in general three approaches to propagate partially coherent light. They include solving the Helmholtz equations for the correlation function, employing the Wigner function to propagate light in phase space, or using modal expansion. In this work, we investigate the interaction of partially spatially coherent light with optical systems. Our modeling methods are based on the Wigner function and modal expansion. First, we utilize the thin element approximation in the Wigner function to propagate partially coherent light through discontinuous surfaces. Our examples include the phase step, grating, kinoform lens, axicon and lens array. Phase space provides a vivid picture for understanding the diffraction effects, e.g. the diffracted orders formed by a grating, the multiple foci of a kinoform lens, and the beam homogenizing effect of a lens array, etc. This approach facilitates the design of diffractive elements and the interpretation of optical effects. Second, we improve the propagation algorithms for the Wigner function. These implementations include removing a parabolic wavefront of a beam, and an efficient propagator based on rotating the phase space. Both algorithms increase the computational speed without losing any physical accuracy. To overcome certain limitations of our phase space propagators, we investigate the modal expansion method. We use Schell beams as examples, to discuss the advantages and disadvantages of eigenmode and shifted-elementary mode expansions. Afterward, we develop an expansion tool to efficiently propagate partially coherent light inside waveguides. This tool allows quick access to the light fields at any distance inside the waveguide. We thus obtain an accurate modeling of the diffraction effects produced by the waveguide structure. Our modeling methods pave the path to the experimental measurement of coherence. We discuss two schemes to retrieve the spatial coherence of a beam under test. The first scheme is to solve an inverse problem of the modal expansion. It requires iterative phase retrieval algorithms to recover the complex fields of individual modes. We extend this method to a beam with an arbitrary wavefront and discuss the potential and limits of this technique. The second scheme for coherence retrieval is to solve the inverse problem of the Wigner function, also known as the phase space tomography. To reconstruct a Wigner function requires an inverse Radon transform in a four-dimensional space. We present an overview of the two relevant algorithms, i.e. the filtered back projection and the ambiguity function reconstruction. Furthermore, we propose an improved algorithm for the filtered back projection.']

Document ### Title: ['Klimaschutz in föderalen Mehrebenensystemen : das Recht der nachfrageorientierten Energieeffizienzförderung in der Europäischen Union und den USA'] ### Abstract: [['The promotion of energy efficiency is seen as a main cornerstone for establishing a sustainable energy system. A complex body of energy efficiency law has emerged within the European Union and the USA, two federal multi-level governance systems, over the last decades. However, the necessary energy efficiency turnaround has not been achieved.Therefore, the question remains open how to make climate protection work in federal multi-level governance systems. How can existing regulations regarding the promotion of end-user oriented energy efficiency be improved in federal multi-level governance systems?The author examines the European and German energy efficiency law in comparison to the US and Californian energy efficiency law and points out the advantages and disadvantages of the energy efficiency promotion in the two legal systems.', 'Die Steigerung der Energieeffizienz ist ein zentraler Baustein für die Schaffung eines nachhaltigen Energiesystems. In den föderalen Mehrebenensystemen Europäische Union und USA hat sich in den letzten Jahrzehnten ein komplexer energieeffizienzrechtlicher Normbestand mit sektorspezifischen und -übergreifenden Regelungen herausgebildet, der die notwendige Energieeffizienzwende bislang allerdings nicht herbeizuführen vermochte. Wie aber kann Klimaschutz in föderalen Mehrebenensystemen gelingen? Wie können die Regelungen zur nachfrageorientierten Energieeffizienzförderung in föderalen Mehrebenensystemen zu einem wohlgeordneten Recht entwickelt werden? Diese Arbeit bietet eine umfassende Darstellung und Bewertung des amerikanischen und kalifornischen Endenergieeffizienzrechts, stellt diesem das europäische und deutsche Endenergieeffizienzrecht gegenüber und untersucht die jeweiligen Lösungsmodelle auf ihre Vor- und Nachteile im Hinblick auf die Herausbildung eines wohlgeordneten Rechts.']] ### GND ID: ['gnd:1135505446', 'gnd:4014715-0', 'gnd:4014733-2', 'gnd:4017754-3', 'gnd:4078704-7', 'gnd:4115712-6', 'gnd:4130688-0', 'gnd:4801271-3', 'gnd:5059953-7', 'gnd:5098525-5', 'gnd:7547705-1', 'gnd:7660153-5', 'https://www.tib.eu/de/suchen/id/TIBKAT%3A890206422'] ### GND class: ['Walker, Benedikt', 'Energiepolitik', 'Energieverbrauch', 'Föderalismus', 'USA', 'Rechtsvergleich', 'Energierecht', 'Mehrebenen-Verflechtung', 'Europa-Universität Viadrina Frankfurt (Oder)', 'Europäische Union', 'Klimaschutz', 'Energieeffizienz'] <|eot_id|>

['Interacting with personal fabrication devices']
['Personal fabrication tools, such as 3D printers, are on the way of enabling a future in which non-technical users will be able to create custom objects. However, while the hardware is there, the current interaction model behind existing design tools is not suitable for non-technical users. Today, 3D printers are operated by fabricating the object in one go, which tends to take overnight due to the slow 3D printing technology. Consequently, the current interaction model requires users to think carefully before printing as every mistake may imply another overnight print. Planning every step ahead, however, is not feasible for non-technical users as they lack the experience to reason about the consequences of their design decisions. In this dissertation, we propose changing the interaction model around personal fabrication tools to better serve this user group. We draw inspiration from personal computing and argue that the evolution of personal fabrication may resemble the evolution of personal computing: Computing started with machines that executed a program in one go before returning the result to the user. By decreasing the interaction unit to single requests, turn-taking systems such as the command line evolved, which provided users with feedback after every input. Finally, with the introduction of direct-manipulation interfaces, users continuously interacted with a program receiving feedback about every action in real-time. In this dissertation, we explore whether these interaction concepts can be applied to personal fabrication as well. ...']

['Lignin valorization : extraction, characterization and applications']
['The topic of this project is the use of lignin as alternative source of aromatic building blocks and oligomers to fossil feedstocks. Lignin is known as the most abundant aromatic polymer in nature and is isolated from the lignocellulosic component of plants by different possible extraction treatments. Both the biomass source and the extraction method affect the structure of the isolated lignin, therefore influencing its further application. Lignin was extracted from beech wood by two different hydrothermal alkaline treatments, which use NaOH and Ba(OH)2 as base and by an acid-catalyzed organosolv process. Moreover, lignin was isolated from bamboo, beech wood and coconut by soda treatment of the biomasses. A comparison of the structural features of such isolated lignins was performed through the use of a wide range of analytical methods. Alkaline lignins resulted in a better candidate as carbon precursor and macromonomers for the synthesis of polymer than organosolv lignin. In fact, alkaline lignins showed higher residual mass after carbonization and higher content of the reactive hydroxy functionalities. In contrast, the lignin source turned out to slightly affect the lignin hydroxyl content. One of the most common lignin modifications is its deconstruction to obtain aromatic molecules, which can be used as starting materials for the synthesis of fine chemicals. Lignin deconstruction leads to a complex mixture of aromatic molecules. A gas chromatographic analytical method was developed to characterize the mixture of products obtained by lignin deconstruction via heterogeneous catalytic hydrogenolysis. The analytical protocol allowed the quantification of three main groups of molecules by means of calibration curves, internal standard and a preliminary silylation step of the sample. The analytical method was used to study the influence of the hydrogenolysis catalyst, temperature and system (flow and batch reactor) on the yield and selectivity of the aromatic compounds. ...']

['Diffuse radio emission at low frequencies in merging galaxy clusters']
['Extended diffuse radio features so-called radio halos radio relics and radio mini-halos are found in about 100 galaxy clusters. The radio emission originates from relativistic electrons suffering synchrotron losses in the magnetized intra-cluster medium. Little is known about the mechanisms how electrons in the intra-cluster medium get accelerated to relativistic energies. Observations at low radio frequencies permit the analysis of the distribution of the population of aged relativistic electrons. In this work we analyzed in the context of the WSRT 346 MHz Legacy Survey ten galaxy clusters with already known diffuse radio sources and yet unclassified sources. We confirm radio relics in three clusters radio halos in five clusters and classified a radio relic candidate as a radio galaxy. Furthermore we revealed radio features with remarkable morphology in the galaxy cluster Abell 2069. Abell 2069 is a complex merging galaxy cluster which shows two distinct X-ray peaks. The main cluster component evidently possesses a radio halo and the subcomponent exhibits ultra-steep spectrum diffuse radio emission of uncertain nature. We conducted follow-up observations on Abell 2069 with LOFAR in the frequency range from 120 to 180 MHz. We complemented our investigation of Abell 2069 with GMRT observations at 322 MHz and 608 MHz as well as with archival Chandra X-ray data. Our analysis confirms the presence of a radio halo in the main cluster component. Furthermore we classify the diffuse radio emission in the subcluster as radio mini-halo. We detected signatures of fossil plasma ejected during a former active phase of an Active Galactic Nuclei in the subcluster. A cold front in the subcomponent suggests the presence of internal gas sloshing which could have induced bulk motions and turbulence in the subcluster. Both mechanisms together may have redistributed and re-accelerated the fossil plasma and caused the diffuse radio emission.']

Document ### Title: ['Diffuse radio emission at low frequencies in merging galaxy clusters'] ### Abstract: ['Extended diffuse radio features so-called radio halos radio relics and radio mini-halos are found in about 100 galaxy clusters. The radio emission originates from relativistic electrons suffering synchrotron losses in the magnetized intra-cluster medium. Little is known about the mechanisms how electrons in the intra-cluster medium get accelerated to relativistic energies. Observations at low radio frequencies permit the analysis of the distribution of the population of aged relativistic electrons. In this work we analyzed in the context of the WSRT 346 MHz Legacy Survey ten galaxy clusters with already known diffuse radio sources and yet unclassified sources. We confirm radio relics in three clusters radio halos in five clusters and classified a radio relic candidate as a radio galaxy.

['Transiting Sub-stellar companions on intermediate-mass stars']
['The aim of the project is to evaluate the predictions from theories of planet formation by determining the absolute frequency of close-in planets of intermediate-mass stars (IMSs). The detection of close-in planets of IMSs can put constraints to the theories of planet formation. First, it is known from infrared observations that the lifetimes of protoplanetary discs of IMSs are half as long as those of solar-mass stars. Second, radial velocity surveys of evolved IMSs show that the frequency of planets at distances larger than 5 AU is higher in comparison to solar-mass stars. However, not much is known about the frequency of close-in planets. An important key to constrain processes of planet formation and evolution is, thus, answering the question: “Is the frequency higher for close-in planets of IMSs than for solar-mass stars?” The transit method is best suited to find such planets. First, it is not affected by the fast rotation of these stars and secondly, it favours the detection of close-in planets. I used the CoRoT database to survey all IMSs observed with this instrument. In contrast to ground- based surveys, the precision of CoRoT allows the detection of all Jupiter-sized transiting objects orbiting IMSs. I first determined the mass-distribution of the stars in the sample. Second I found 14 transit candidates of IMSs in the CoRoT survey and observed them spectroscopically to determine their masses. In result, I detected one planet as well as two very young brown dwarfs with large radii of IMSs by this survey. Among them, the first transiting brown dwarf of a B-type star. The frequency for close-in planets of IMSs derived from this survey is 0.11 ± 0.04 %. This means that close-in sub-stellar companions of IMSs are rare. In the context of disc-migration, this surprising result can be explained by the lifetime of the protostellar discs of IMSs. It is apparently long enough for the planets to form, but on average too short for them to migrate inwards.']

['New approaches to locally adaptive nonparametric estimation and inference']
['Abstract: This thesis is concerned with new approaches to locally adaptive estimation and inference. More specifically, this work focusses on estimation and inference related to probability densities in the framework of nonparametric statistics. Indeed, it investigates both on adaptation to lowest density regions and on locally adaptive confidence bands. The two distinct topics are presented in two self-contained chapters. <br>In the first chapter, a scheme for locally adaptive bandwidth selection is proposed which sensitively shrinks the bandwidth of a kernel estimator at lowest density regions, such as the support boundary, which are unknown to the statistician. In case of a Hölder continuous density, this locally minimax-optimal bandwidth is shown to be smaller than the usual rate, even in case of homogeneous smoothness. A new type of risk bound with respect to a density-dependent standardized loss of this estimator is established. This bound is fully non-asymptotic and allows to deduce convergence rates at lowest density regions that can be substantially faster than n^(-1/2). It is complemented by a weighted minimax lower bound which splits into two regimes depending on the value of the density. The new estimator adapts into the second regime, and it is shown that simultaneous adaptation into the fastest regime is not possible in principle as long as the Hölder exponent is unknown. Consequences on plug-in rules for support recovery are worked out in detail. In contrast to those with classical density estimators, the plug-in rules based on the new construction are minimax-optimal, up to some logarithmic factor. <br>In the second chapter, we develop honest and locally adaptive confidence bands for probability densities. They provide substantially improved confidence statements in case of inhomogeneous smoothness, and are easily implemented and visualized. The thesis contributes conceptual work on locally adaptive inference as a straightforward modification of the global setting imposes severe obstacles for statistical purposes. We introduce a statistical notion of local Hölder regularity and prove a correspondingly strong version of local adaptivity. We substantially relax the straightforward localization of the self-similarity condition in order not to rule out prototypical densities. The set of densities permanently excluded from the consideration is shown to be pathological in a mathematically rigorous sense. On a technical level, the crucial c ...']

In case of a Hölder continuous density, this locally minimax-optimal bandwidth is shown to be smaller than the usual rate, even in case of homogeneous smoothness. A new type of risk bound with respect to a density-dependent standardized loss of this estimator is established. This bound is fully non-asymptotic and allows to deduce convergence rates at lowest density regions that can be substantially faster than n^(-1/2). It is complemented by a weighted minimax lower bound which splits into two regimes depending on the value of the density. The new estimator adapts into the second regime, and it is shown that simultaneous adaptation into the fastest regime is not possible in principle as long as the Hölder exponent is unknown. Consequences on plug-in rules for support recovery are worked out in detail. In contrast to those with classical density estimators, the plug-in rules based on the new construction are minimax-optimal, up to some logarithmic factor. <br>In the second chapter, we develop honest and locally adaptive confidence bands for probability densities. They provide substantially improved confidence statements in case of inhomogeneous smoothness, and are easily implemented and visualized. The thesis contributes conceptual work on locally adaptive inference as a straightforward modification of the global setting imposes severe obstacles for statistical purposes. We introduce a statistical notion of local Hölder regularity and prove a correspondingly strong version of local adaptivity. We substantially relax the straightforward localization of the self-similarity condition in order not to rule out prototypical densities. The set of densities permanently excluded from the consideration is shown to be pathological in a mathematically rigorous sense.

In this work, on the one hand, we concentrate on studying some further properties of Besov-Triebel-Lizorkin spaces of dominating mixed smoothness such as pointwise multiplication, characterization by mixed differences, and change of variable operators which are connected to numerous applications. On the other hand, we investigate the order of convergence of Weyl and Bernstein numbers of compact embeddings of tensor product Sobolev and Besov spaces into Lebesgue spaces on the unit cube.

['Bogotá as a Spatial Sign: A Semiotic Reading of Urban Centrality in Latin America']
['This project proposes and applies a research strategy to understand types of cities using the case study of Bogotá. This strategy combines a conceptual framework developed around the notion of ‘centrality’ and ‘urban semiotics’ as a method of qualitative enquiry in order to comprehend complex spatial arrangements as significant constituents of cultural geographies. In this sense, this study problematizes current tendencies such as spatial fragmentation and challenges the argument that contemporary urban ensembles in Latin America are either homogenized within globalization trends or illegible entities with no structural coherence. Bogotá is addressed as an instrumental case study to redraw generalizations developed from different methodological frameworks about the configuration process of spatial structures and their significance within the Latin American geography. Thus the study questions how urban centrality has evolved as an essential socio-cultural phenomenon and in this manner decodes the messages transmitted by main spatial arrangements. As a first step, the study discusses the construction of spatial meaning and its structural interpretation. In addition, the concept of centrality is examined in depth and an urban centrality typology is introduced to enable the analysis of spatial structures in socio-cultural terms. These contents are followed by the discussion of the existing approaches to the topic and their limitations. Subsequently, this research reconstructs the configuration of Bogotá’s spatial structure which is decoded in the last chapter. The study concludes that the highly fragmented and uneven condition of urban space in Latin America can be read. The case study of Bogotá substantiates that there is a code that paradoxically provides spatial cohesiveness within unstable socio-spatial hierarchies. Such a spatial code is deciphered through the reading of Bogotá’s spatial structure whose super-centre denotes ‘the sacralisation of authoritarianism’. This is a ‘structural meaning’ related to a specific or intrinsic logic of spatial concentration that is useful for the further discussion of socio-spatial patterns and the meanings of Latin American cities.

['Analysis of photonic structures for silicon solar cells']
['Abstract: Integrating photonic structures into the surface is an established procedure to enhance the energy conversion efficiency of silicon solar cells.

['Ultra-hoch gefüllte und orientierte CNT- und 3D-vernetzte Aerographit Epoxidkomposite : Synthese, Herstellung und Eigenschaften']
[["In this work two different polymer nanocomposites (PNCs) with graphitic fillers in epoxy matrix are characterized. Both PNCs possess structural features, which are used to address open scientific questions in the field of carbon nanotube (CNT) based PNCs. The PNCs of this work use in-house synthesized nanoparticles, which are: mm-long, unidirectional aligned carbon nanotubes (CNTs) and covalently 3D interconnected graphite-based networks ('Aerographite', AG). For CNT-based PNCs (CNT-PNCs) a manufacturing method is introduced (patented), which allows to embed very high amounts of CNTs in epoxy matrix (Φ= 10-70 wt.%). Two different structures are given for these CNT-based PNCs: APNCs: PNCs with unidirectional alignment of mm-long, in-house produced CNTs (anisotropic). RPNCs: PNCs with randomly oriented CNTs (mm-long in-house produced CNTs or µm-long commercial CNT) (isotropic). AG-PNCs: Aerographite-based PNCs are PNCs with an isotropic, covalently interconnected graphite filler network embedded in epoxy matrix (Φ<1\u2009wt.%) (isotropic). Here different orientations, different aspect ratios and different qualities of CNTs are directly compared. The scaling of electrical conductivity and Young's moduli in respect to filler loadings are in focus of the investigations (σ (Φ) , E(Φ)). The piezoresistive and thermoelectric behavior of CNT-based PNCs with filler loadings Φ >5\u2009wt.% are investigated here for the first time. The findings for CNT-PNCs are combined with the results on AG-PNCs. The influence of inner network topologies on electrical conduction is discussed in detail. If the graphitic networks of AGs are infiltrated with epoxy, AG-PNCs of low filler loading and isotropic structure result. Inner graphite elements of AGs are covalently interconnected. Therefore AG-PNCs can be used to investigate the influence of reduced electron tunneling on the electrical conduction and piezoresistive behavior of PNCs. It can be shown, that highly filled APNCs can lead to highly improved material properties like electrical conductivities up to σ= 37000\u2009S/m and Youngs's moduli up to E= 36\u2009GPa. On the other hand APNCs are shown to follow similar scaling rules of electrical conduction (σ(Φ)), as they had been derived from dispersed CNT-PNCs in the last two decades of research. The inner interconnections of AG lead to -\u2009compared to all of today's CNT-based PNCs\u2009- effective electrical conduction (σ/Φ). Appendix: Aerographite (AG): In the year 2010 first time a metal oxide (ZnO) was shown to be a feasible substrate for graphite deposition via a chemical vapor deposition process (CVD). Technically no other synthesis offers following combination: (i) structuring by tailored ceramic networks & graphite deposition with in situ removal of template. The density and inner structure of AG can be altered by the CVD-process. Scientifically the details of nucleation and growth of graphite within the CVD-process is not yet fully understood. To continue the research, the appendix deal with following contents: Development of synthesis & outlook on structuring Statistics of CVD-processes (2010-2015) & introduction of one control parameter for selecting variant and density of AGs Structural analyses (SEM, TEM, SAEDs, XRD,…) & introduction of a hypothetical growth model", 'Diese Arbeit behandelt die Herstellung und Charakterisierung von Polymernanokompositen (PNCs). Es werden zwei graphitische Füllstoffe in Epoxidmatrix untersucht: Kohlenstoffnanotubes (CNTs) und “Aerographit” (AG). Die PNCs dieser Arbeit unterscheiden sich hinsichtlich Füllstoffgehalt und Morphologie wie folgt: CNT-basierte PNCs (CNT-PNCs): PNCs mit unidirektionaler Ausrichtung (APNCs, anisotrop) und willkürlicher Ausrichtung (RPNCs, isotrop) von CNTs. Es wird der Bereich von Φ= 10-68\u2009wt.% Gewichtsanteil untersucht. AG-basierter PNCs (AG-PNCs): PNCs mit 3D-vernetzten Graphitnetzwerken in Epoxidmatrix. Die inneren Elemente sind isotrop orientiert und kovalent vernetzt. Es wird der Bereich Φ= 0,2-0,6\u2009wt.% Gewichtsanteil untersucht. Die Skalierung der elektrischen Leitfähigkeit und die Skalierung der E-Moduln werden bei bisher nicht vorhandener Variationsbreite der CNT-Gewichtsanteilen untersucht (σ (Φ) , E(Φ)). Eine zentrale Fragestellung ist, wie sich eine strenge Anisotropie (CNT-PNCs) oder eine kovalente Vernetzung (AG-PNCs) auf die Effizienz der elektr. Leitung pro Füllstoffanteil (σ/Φ) auswirkt. Speziellere Fragen sind u.a.: Wie wird die Piezoresistivität von CNT-PNCs beeinflusst, wenn die Abstände zwischen CNTs so weit reduziert werden, dass sie im Bereich ihrer Abmessungen liegen? Dominiert eher die Orientierung der CNTs oder der Füllstoffanteil der CNTs das piezoresistive und thermoelektrische Verhalten von CNT-PNCs? Lassen sich maximale Grenzen für E-Moduln und elektr. Leitfähigkeiten von CNT-PNCs ableiten? Methodisch ist wird die Untersuchung durch ein neues Herstellungsverfahren für APNCs/RPNCs möglich (Patent). Hierbei können sehr verschiedene Arten von CNTs verarbeitet werden. Struktur-Eigenschafts-Beziehungen werden anhand von gerichteten in-house MWCNTs (l> 1,3\u2009mm), ungerichteten in-house MWCNTs (l> 1,3\u2009mm) und ungerichteten kommerziellen MWCNTs ( l=0,01\u2009mm) betrachtet. Die APNCs u. RPNCs dieser Arbeit werden mit dem bisherigen Wissen über dispergierte CNT-PNCs verglichen. Dispergierten CNT-PNCs weisen i.d.R. nur keine Orientierung der CNTs und nur niedrige Füllstoffanteile auf. Mit den APNCs können weit gesteigerte Materialkennwerte erreicht werden (APNCs: σ= 37000\u2009S/m, E= 36\u2009GPa; RPNCs: σ= 3000\u2009S/m, E= 6\u2009GPa). Es kann hier gezeigt werden, dass die elektrische Leitfähigkeit von hoch gefüllten APNCs ähnlichen Skalierungsregeln σ (Φ) folgt, wie sie für dispergierte CNT-PNCs abgeleitet sind. Die isotropen und kovalent vernetzten Graphitnetzwerke des Aerographits können vollständig mit Epoxiden gefüllt werden. Die resultierenden AG-PNCs sind hinsichtlich Füllstoffanteile und Isotropie mit typischen dispergierten CNT-PNCs vergleichbar. Es wird die Auswirkung einer reduzierten Tunnelleitung das piezoresistive Verhalten und die elektr. Leitfähigkeit von PNCs mit graphitischen Füllstoffen untersucht. Eine gegenüber allen bisherigen CNT-PNCs (dispergierte CNT-PNCs u. hoch gefüllte APNCs/RPNCs) erhöhte Effizienz der elektr. Leitung pro Füllstoffanteil (σ / Φ) kann gezeigt werden. Anhang zum Aerographit: Eine im Jahr 2010 entdeckte Synthese ermöglicht es graphitische Strukturen auf dem Metalloxid Zinkoxid (ZnO) abzuscheiden. In dem chemischen Gasphasenabscheidungsprozess (CVD) kann umfangreich Einfluss auf die innere Struktur und Dichte genommen werden (Patent). Es sind drei Hauptvarianten des AGs bekannt. Diese unterscheiden sich grundlegend in der Struktur der inneren Graphitwände und/oder Füllungen. Die Kinetik der Entfernung des Templates und der Nukleation von Graphit im CVD-Prozess ist bisher nur ansatzweise verstanden.

['Polymer Mach-Zehnder interferometers for refractive index sensing']
['Abstract: This thesis presents polymeric Mach-Zehnder interferometers (MZI) for refractive index sensing. These interferometers are designed as asymmetric Mach-Zehnder interferometers (AMZIs), meaning that, when compared with the conventional MZI, the devices have no interaction window on the sensing arm. The asymmetricity is realized by designing the sensing arm and reference arm with different widths. The analyte of interest, acting as the cladding layer, covers the entire surface. The phase shift is induced by the external refractive index change due to the different sensitivities of the two arms.<br>Polymers with variable refractive index and viscosity allow great flexibility in design and fabrication. The transfer from traditional photo-lithography to the roll-to-roll process of polymer AMZIs enables us to fabricate cost-efficient sensors on a flexible platform. The thermal expansion and thermo-optic co-efficient of the customized polymers and PMMA substrate are characterized experimentally, and the data are used in the temperature simulations of AMZIs.<br>Four design types of AMZIs, using either curved tapers on the Y-couplers or straight tapers on the sensing arm, are presented. Extensive simulation and experimental results show the functionality of the AMZI to external refractive index change with a limit of detection (LOD) in the order 10−3 refractive index units (RIU). Temperature simulation of the AMZIs indicates a signal change of 1% per degree within temperature range 10 to 60 ◦C.<br>In addition, to enhance the sensitivity of the AMZIs, a simple yet efficient method is presented using tailored high-index thin films on the surface of the core layer. Simulation and experimental results show that a properly-placed PTFE/Ta2O5 thin film can lead to enhanced sensitivity of AMZIs to refractive index changes of factors between 3 and 8. The thin films are deposited on the polymer surface using ion beam sputtering at low temperatures (< 80◦C) thereby avoiding detrimental heating effects on the substrate. It is shown that LOD of the AMZIs is enhanced by a factor 10 (down to Δn ≤ 10−4) using these films']

After a short overview of the basic principles of the private enforcement, the author indicates which legal instruments are by now available to gain insight into the leniency documents which are protected by the antitrust authorities, during the pre-trial and current trial procedure stadium and what need for adoption the private enforcement directive has for the national law. Furthermore, consideration is given in how far the incalculable protection of leniency documents infringes primary European law in the form of the Articles 101 and 102 AEUV and the right of evidence in accordance with Article 47 of the Charter of Fundamental Rights of the European Union.', 'Kronzeugenerklärungen bilden ein substanzielles Beweismittel privater Kartellschadensersatzklagen. Die Verhinderung ihrer Offenlegung ist ein zentrales Regelungselement der neu geschaffenen Kartellschadensersatzrichtlinie 2014/104/EU. Der Autor zeigt nach einer überblicksartigen Einführung in die Grundlagen der Durchsetzung privatrechtlicher Kartellschadensersatzansprüche auf, welche rechtlichen Instrumentarien Kartellgeschädigten bisher zur Verfügung standen, um im vorprozessualen und innerprozessualen Stadium Einsicht in die von den Behörden geschützten Kronzeugendokumente zu erhalten, und welchen Anpassungsbedarf für das nationale Beweisrecht die Kartellschadensersatzrichtlinie nunmehr mit sich bringt. Darüber hinaus wird eingehend dargestellt, dass der unabwägbare Schutz von Kronzeugenerklärungen mit unionalem Primärrecht in Gestalt der Artt. 101 und 102 AEUV und dem durch Art. 47 der Grundrechtecharta der Europäischen Union gewährleisteten Recht auf Beweis konfligiert.']] ### GND ID: ['gnd:1082301779', 'gnd:1136979220', 'gnd:4003809-9', 'gnd:4011882-4', 'gnd:4116364-3', 'gnd:4123581-2', 'gnd:4141722-7', 'gnd:4145175-2', 'gnd:4163368-4', 'gnd:4456298-6', 'gnd:7849416-3', 'https://www.tib.eu/de/suchen/id/TIBKAT%3A894844687'] ### GND class: ['Kartellschadensersatzrichtlinie', 'Dawirs, Gordon', 'Aussage', 'Deutschland', 'Schadensersatzanspruch', 'Kronzeuge', 'Akteneinsicht', 'Beweismittel', 'Kartellverstoß', 'Zeugenschutz', 'EBS Law School'] <|eot_id|>

['Das Eigentumsrecht in Deutschland und der VR China : Genese, Status quo und Entwicklungsperspektiven aus rechtsvergleichender Sicht']
[['In 2004 China has adopted a new provision on the constitutional protection of property, followed by several implementing laws and regulations. From this and from a stated increasing development of capitalist structures and corresponding legislative activity one may infer that China endorses the principle of rule of law. Yet, how does “China” perceive these notions of rule of law and protection of property? In this dissertation, the author addresses these issues by comparing the distinct Chinese and German legal regimes of property. He emphasises the significance of cultural contexts and underlying socio-political structures that coin the property system and legal thinking of an entity by elucidating the respective historical underpinnings as well as aspects of legal philosophy and constitutional doctrine. The author goes beyond a mere legal comparison and assessment of the status quo, in that he evaluates whether specific notions of the German constitution may pave the way for a sound development of Chinese property law.', 'Die Verfassung der Volksrepublik China kennt seit 2004 die Gewährleistung des privaten Eigentums, nachfolgende gesetzliche Normen haben diese konkretisiert. Im Zuge vermehrter kapitalistischer Strukturen und einer regen Rechtssetzungstätigkeit mag China vielen auf dem Weg zu einem Rechtsstaat erscheinen. Wie werden Rechtsstaatlichkeit und Eigentumsgewährleistung dort aber begriffen? Der Beschreibung der deutschen Rechtslage stellt der Autor die insoweit gänzlich andere Auffassung der chinesischen Eigentumsordnung gegenüber. Indem er dabei die jeweiligen historischen, rechtsphilosophischen und verfassungsdogmatischen Aspekte analysiert, legt er besonderen Wert auf den rechtskulturellen Kontext und die sozio-politischen Tiefenstrukturen, die das Eigentum prägen. Das Werk geht über eine reine rechtsvergleichende Zustandsbeschreibung dabei hinaus, indem der Autor sich an der Idee versucht, ob konkrete Ideen der deutschen Eigentumsordnung der chinesischen Entwicklung Impulse geben könnten.']]
