A study Group of the ESONE Committee has been exploring possible ways to extend the use of the CAMAC Dataway (1) in a manner that will maintain compatibility with existing CAMAC hardware. Major areas having attention are greatly increased addressing within a module, handshake timing on the dataway and a mechanism to allow Auxiliary Controllers to address modules in other crates. These extensions will allow those users and. manufacturers who already have a commitment to CAMAC to better exploit new devices, such as large RAMs, that are now available. This paper describes the objectives and the present progress that has been made.

During the past 18 months, over 300 physicists and engineers have participated in a Working Group, set up by the European Committee for Future Accelerators (ECFA), to study a project for a Large Electron Positron colliding-beam machine (LEP), in Europe in the 1980s. 20 specialized subgroups have investigated technical questions in various areas, and the likely impact of LEP on subnuclear physics and the physics community. The data-handling subgroups have concluded that techniques currently available, with continued development, will be adequate to meet the technical requirements of LEP experiments. However, there is an urgent need for standard practices at all levels of data handling, to ensure that experiments can be carried out by collaborations involving large numbers of physicists from many institutes.

While spherical distributions have been used in many statistical models for high-dimensional data analysis, there are few easily implemented statistics for testing spherical symmetry for the underlying distribution of high- dimensional data. Many existing statistics for this purpose were constructed by the theory of empirical processes and turn out to converge slowly to their lim- iting distributions. Some existing statistics for the same purpose were given in the form of high-dimensional integrals that are not easily evaluated in numer- ical computation. In this paper, we develop some necessary tests for spherical symmetry based on both univariate and multivariate uniform statistics. These statistics are easily evaluated numerically and have simple limiting distribu- tions. A Monte Carlo study is carried out to demonstrate the performance of the statistics on controlling type I error rates and power.

An omnibus test for spherical symmetry in ℝ2 is proposed, employing localized empirical likelihood. The thus obtained test statistic is distribution free under the null hypothesis. The asymptotic null distribution is established and critical values for typical sample sizes, as well as the asymptotic ones, are presented. In a simulation study, the good performance of the test is demonstrated. Furthermore, a real data example is presented.

Capacitance extraction for three-dimensional (3-D) conductors located on planar structures has various applications, especially in the design and packaging of integrated circuits. One of the most commonly used methods for capacitance extraction problems is the method of moments (MM). In this study, the forward-backward (FB) method, which is an iterative MM, is applied for solving these problems effectively. It is found that the method is an O(N/sup 2/) algorithm per iteration, where N is the total number of unknowns. In addition, the FB method provides accurate results compared to those of the standard MM with less computational times for relatively large problems. Convergence characteristics of the FB method are also studied in this paper.

A new technique called "forward-backward," has been developed for solving the magnetic field integral equation (MFIE) for perfectly conducting azimuthally homogeneous surfaces, including cases where the incident radiation has a lowgrazing angle. The technique involves splitting both the surface current and the MFIE into two pieces; one representing primarily forwardly scattered energy and one representing primarily backwardly scattered energy. Each of the new integral equations can be solved by an iterative stepping procedure. The technique is applied to two sample problems–the classic Sommerfeld wedge and a peaked surface consisting of two filtered exponentials. The obtained solutions are shown to be accurate for each of these problems.

Recoil tritium reactions with 1,2-difluoroethylenes
|
Recoil tritium reactions with cis- and trans-CHF=CHF have been studied. The results indicate that the majority of the tritium-labeled parent molecules are formed via the direct T-for-H substitution process and that the geometric isomers are formed via unimolecular isomerization of the excited parent molecules. On the other hand, the recoil tritium addition process will give rise to an excited radical that immediately converts to a bridged complex. Such a bridged complex may either isomerize to effect a net 1,2 F-atom migration to give CHT=CF/sub 2/ as the final product or expel an F-atom to form CHT=CHF.

We study the basic properties of tensor random fields (TRFs) of the wide-sense homogeneous and isotropic kind with generally anisotropic realizations. Working within the constraints of small strains, attention is given to antiplane elasticity, thermal conductivity, classical elasticity and micropolar elasticity, all in quasi-static settings albeit without making any specific statements about the Fourier and Hooke laws. The field equations (such as linear and angular momentum balances and strain–displacement relations) lead to consequences for the respective dependent fields involved. In effect, these consequences are restrictions on the admissible forms of the correlation functions describing the TRFs.

In this paper, we consider the second order wave equation discretized in space by summation-by-parts-simultaneous approximation term (SBP-SAT) technique. Special emphasis is placed on the accuracy analysis of the treatment of the Dirichlet boundary condition and of the grid interface condition. The result shows that a boundary or grid interface closure with truncation error $\mathcal{O}(h^p)$ converges of order $p + 2$ if the penalty parameters are chosen carefully. We show that stability does not automatically yield a gain of two orders in convergence rate. The accuracy analysis is verified by numerical experiments.

A NONCONFORMING PENALTY METHOD FOR A TWO-DIMENSIONAL CURL–CURL PROBLEM
|
A nonconforming finite element method for a two-dimensional curl–curl problem is studied in this paper. It uses weakly continuous P1 vector fields and penalizes the local divergence. Two consistency terms involving the jumps of the vector fields across element boundaries are also included to ensure the convergence of the scheme. Optimal convergence rates (up to an arbitrary positive ∊) in both the energy norm and the L2 norm are established on graded meshes. This scheme can also be used in the computation of Maxwell eigenvalues without generating spurious eigenmodes. The theoretical results are confirmed by numerical experiments.

We describe preliminary results from an effort to quantify the uncertainties in parton distribution functions and the resulting uncertainties in predicted physical quantities. The production cross section of the $W$ boson is given as a first example. Constraints due to the full data sets of the CTEQ global analysis are used in this study. Two complementary approaches, based on the Hessian and the Lagrange multiplier method respectively, are outlined. We discuss issues on obtaining meaningful uncertainty estimates that include the effect of correlated experimental systematic uncertainties and illustrate them with detailed calculations using one set of precision DIS data.

‘Monte carlo’ computer simulation of chain molecules: II. The limiting distribution of end‐to‐end distance for two‐dimensional excluded‐volume chains
|
A computer technique for simulating configurational behaviour of chains, developed previously, was used to study the nature of the distribution of the magnitude of end-to-end vectors of excluded-volume chains constrained to two dimensions. The study revealed that the above distribution in the limit of infinite chain length deviates greatly from Gaussian behaviour and that the deviation is much greater than for three-dimensional chains. The probability distribution function A exp (—αR5.8) was derived.

The long-term effects of a distant third-body on a massless satellite that is orbiting an oblate body are studied for a high order expansion of the third-body disturbing function. This high order may be required, for instance, for Earth artificial satellites in the so-called MEO region. After filtering analytically the short-period angles via averaging, the evolution of the orbital elements is efficiently integrated numerically with very long step-sizes. The necessity of retaining higher orders in the expansion of the third-body disturbing function becomes apparent when recovering the short-periodic effects required in the computation of reliable osculating elements.

Crystal size distribution dynamics in a classified crystallizer: Part I. Experimental and theoretical study of cycling in a potassium chloride crystallizer
|
Cycles in particle size and slurry density were experimentally observed in a mixed suspension, potassium chloride crystallizer equipped with a fines dissolver and having nonrepresentative product withdrawal. Cycling behavior was achieved with a product crystal elutriator but was also observed with changes in the orientation of the product removal tube, indicating that instability was induced by product classification. Simulation of the unstable runs with a dynamic model showed crystal size distribution (CSD) limit cycles of similar period using nucleation kinetics and process conditions measured experimentally. The computer simulation showed no tendency towards cycling for the stable runs.

Battery models play important roles in battery manufacturing, design, safe operation, and many of its applications, such as in providing power sources of electric vehicles due to the high energy density, long life, and high cell voltage. Unlike the detection of impedance spectrum in a short linear interval, the I-V characteristic of lithium-ion batteries presents strongly nonlinearity such as the serious polarization in both ends of charging /discharging. To modeling the nonlinear characteristic of real battery accurately, this paper proposes a variable-order fractional equivalent circuit model that provides a novel and effective trade-off of model accuracy and simplicity. The proposed method is verified under the working conditions of pulse and constant current charging /discharging, where the maximum model error is less than 1.8%.

Glassy states in fermionic systems with strong disorder and interactions
|
We study the competition between interactions and disorder in two dimensions. Whereas a noninteracting system is always Anderson localized by disorder in two dimensions, a pure system can develop a Mott gap for sufficiently strong interactions. Within a simple model, with short-ranged repulsive interactions, we show that, even in the limit of strong interaction, the Mott gap is completely washed out by disorder for an infinite system for dimensions $D\ensuremath{\le}2$, leading to a glassy state. Moreover, the Mott insulator cannot maintain a broken symmetry in the presence of disorder. We then show that the probability of a nonzero gap as a function of system size falls onto a universal curve, reflecting the glassy dynamics. An analytic calculation is also presented in one dimension that provides further insight into the nature of slow dynamics.

This work describes a high order accurate discontinuous finite element method for the numerical solution of the equations governing compressible inviscid flows. Our investigation has focused on the problem of correctly prescribing the boundary conditions along curved boundaries. “Ale show by numerical testing that, in the presence of curved boundaries, a high order approximation of the solution requires a corresponding high-order approximation of the geometry of the domain. Numerical solutions of transonic flows are presented which illustrate the versatility and the accuracy of the proposed method.

Power-like decreasing solutions of the linearized Boltzmann equation for neutron thermalization and hard sphere interactions
|
In the neutronic and hard sphere cases, for non discrete eigenvalues we consider eigenfunctions of the linearized Boltzmann equation decreasing like powers of the velocity. The possible existence of such solutions would imply that there is no minimal relaxation rate to equilibrium. Here we show that they must be rejected because they violate the physical requirement of conservation of mass or energy.

Extended analysis of the system of even configurations of Ta II

Abstract We performed a parametric study of the fine (fs) and hyperfine structure (hfs) for the even parity configurations of ionized tantalum (Ta II) using improved experimental fs and hfs data for 88 levels. A multi-configuration fitting procedure was performed for 47 configurations taking into account second-order perturbation theory including the effects of closed to open shell excitations. The fs and hfs parameters were calculated. Predicted values of level energies up to 86 000 cm − 1 are given, as well as g J -Lande factors, magnetic dipole and electric quadrupole hyperfine structure constants A and B , when no experimental values are available.

Free vibrations of a generally restrained rectangular plate with an internal line hinge
|
This paper deals with the study of free transverse vibrations of rectangular plates with an internal line hinge and elastically restrained boundaries. The equations of motion and its associated boundary and transition conditions are rigorously derived using Hamilton’s principle. The governing eigenvalue equation is solved employing a combination of the Ritz method and the Lagrange multipliers method. The deflections of the plate and the Lagrange multipliers are approximated by polynomials as coordinate functions. The developed algorithm allows obtaining approximate solutions for plates with different aspect ratios, boundary conditions, including edges elastically restrained by both translational and rotational springs, and arbitrary locations of the line hinge. Therefore, a unified algorithm has been implemented. Sets of parametric studies are performed and the results are given in graphical and tabular form.

Using close-coupling calculations of Burke and Moores for the scattering of electrons by ${\mathrm{Mg}}^{+}$ ions in the $3^{2}S_{\frac{1}{2}}$ and $3^{2}P_{\frac{1}{2},\frac{3}{2}}$ states, Baranger's expression for the impact approximation width of an isolated line is implemented for the components of the resonance doublet. These widths are extrapolated to below inelastic thresholds and averaged over elastic resonances according to theoretical threshold laws. In the experimental energy range, results compare reasonably with semiclassical approximations and with a semiempirical method involving effective Gaunt factors extrapolated to zero electron energy.

LINEAR RESONANCE ANALYSIS OF BEAMS WITH INTENSE SPACE CHARGE IN THE UNIVERSITY OF MARYLAND ELECTRON RING (UMER)

Space charge can significantly affect the resonant properties of rings. The University of Maryland Electron Ring is a scaled experiment in which we have circulated beams with unprecedented intensities. Here we discuss the resonance analysis performed using the electrostatic particlein-cell code WARP, to understand the effect of space charge on the ring resonances. Beams with varying degrees of space charge in both the emittance-dominated and spacecharge-dominated regimes are attempted. The operating point is scanned to map the tune diagram under various lattice and injection errors. The results of the simulation study are compared to experimental measurements.

Computational study of frontier orbitals, moments, chemical reactivity and thermodynamic parameters of sildenafil

Analysis of frontier orbitals of sildenafil has been carried using Density Functional Theory. On the basis of HOMO-LUMO energy, values of global chemical reactivity descriptors such as electronegativity, chemical hardness, softness, chemical potential, electrophilicity index have been calculated. Calculated values of dipole moment, polarizability, hyperpolarizability have also been reported for sildenafil along with its thermodynamic parameters.

We argue that in the measured $p_T$ domain of RHIC, collisional rather than the radiative energy loss is the dominant mechanism for jet quenching. Accordingly we calculate nuclear suppression factor for light hadrons by taking only the elastic energy loss in sharp contrast with the previous calculations where only the radiative loss are considered.

An extension of the ELECTRE approach with multi-valued neutrosophic information
|
In this paper, an extension Elimination and Choice Translating Reality (ELECTRE) method is introduced to handle multi-valued neutrosophic multi-criteria decision-making (MCDM) problems. First of all, some outranking relations for multi-valued neutrosophic numbers (MVNNs), which are based on traditional ELECTRE methods, are defined, and several properties are analyzed. In the next place, an outranking method to deal with MCDM problems similar to ELECTRE III, where weights and data are in the form of MVNNs, is developed. At last, an example is provided to demonstrate the proposed approach and testify its validity and feasibility. This study is supported by the comparison analysis with other existing methods.

The Knight shift data reveal a suppression of the hyperfine coupling to the In(1) site as a function of pressure, and the electric field gradient, $\nu_{\alpha\alpha}$, at the In(2) site exhibits a change of slope, $d\nu_{\alpha\alpha}/dP$, at $P_{c1} = 1.75$ GPa. These changes to these coupling constants reflect alterations to the electronic structure at the quantum critical point.

A theoretical study of low-energy position diffraction

In an exploratory study of the diffraction of slow positrons from atoms and single-crystal surfaces, theoretical intensity and spin polarization results from a W crystal-atom and a W(001) surface are compared to corresponding electron diffraction results obtained with and without an exchange potential. In contrast to e- diffraction, significant spin polarization effects are found for e+ only at energies above about 100 eV. The computing time for e+ is about half of the time required for e-.

Summary In this abstract, we propose a new finite-difference scheme for solving wave equations. This scheme splits the multidimensional system into different directions and solves each direction implicitly. Unlike most splitting methods in the literature which produce numerical anisotropy in diagonal directions, this method gives perfect circular impulse responses and allows lateral velocity variations. In this paper, we prove that the proposed scheme is unconditionally stable. In the numerical examples, we show some impulse response tests and compare them with the results from some high-order explicit finite-difference methods. The new method allows larger time step and requires less memory storage during the reverse time

Generally, in order to extract electrical circuit parameters of package, specific test fixtures composed of short, open, and thru patterns are required. However, electrical parasitic of the test fixtures makes it difficult to extract accurate circuit parameters of the package. In addition to this the values of the parameters are different according to the electrical configurations of adjacent pins like floating, dc biasing, and applying RF signal. In this paper, we presented a new modeling technique of electronic package considering measurement environments. Electrical parasitic components effect on capacitance and inductance of the package are considered in the proposed modeling technique. The modeling technique is verified through comparison between the measured S-parameter by VNA and the results by AC analysis.

Wave motion over two submerged layers of horizontal thick plates
|
This study investigates the hydrodynamic performance of a submerged two layer horizontal plate breakwater. The plate thickness is considered as non-zero in the study. In the context of linear potential theory, an analytical solution for interaction of water waves with the plates is obtained using the matched eigenfunction expansion method. The solution consists of a symmetric part and an antisymmetric part. Its validity is confirmed by comparing the numerical results of reflection and transmission coefficients for limiting cases with previous predictions. Numerical examples are given to examine the major factors that affect the reflection and transmission coefficients of the plates. Some useful results are presented for engineering design.

Classical S‐matrix calculation for vibrationally inelastic transitions in three dimensional collisions of Li+ with H2
|
The ``partially averaged'' version of classical S‐matrix theory is applied to three dimensional collisions of Li+ with H2. For an initial collision energy of 0.684 eV cross sections for the vibrational deactivation of H2 from the initial state (n1,j1) = (1, 0) to final states (n2,j2), n2 = 0, j2 = 0, 2, 4,... are computed and compared with the recent quantum mechanical coupled channel calculations of Schaefer and Lester. The agreement is quite good, indicating that this approach is an accurate and practical way of describing these weak, ``classically forbidden'' processes which cannot be treated by ordinary classical trajectory methods.

Abstract The torsional impact response of a penny-shaped crack lying on a bimaterial interface is considered in this study. Laplace and Hankel transforms are used to reduce the problem to the solution of a pair of dual integral equations. The solution to the dual integral equations is expressed in terms of a Fredholm integral equation of the second kind with a finite integral kernel. A numerical Laplace inversion routine is used to recover the time dependence of the solution. The dynamic stress intensity factor is determined and its dependence on time and material constants is discussed.

Carefully converged calculations are performed for the band gap of ZnO within many-body perturbation theory (G^0 W^0 approximation). The results obtained using four different well-established plasmon-pole models are compared with those of explicit calculations without such models (the contour-deformation approach). This comparison shows that, surprisingly, plasmon-pole models depending on the f-sum rule gives less precise results. In particular, it confirms that the band gap of ZnO is underestimated in the G^0 W^0 approach as compared to experiment, contrary to the recent claim of Shih et al.

A matlab toolbox for modelling viscoelastic constitutive equation has been implemented. It can be used to analysis the rheology properties of various viscoelastic constitutive equations by solving a time dependent PDE. The toolbox also provides support to calculate the optimized parameter of parameters to give a fine approximation with experiment data. We carefully designed the framework to make sure its extensibility and efficiency. Matlab parallel technology has been add to make the toolbox more computational efficient. The tool box does well on the rheology analysis of Rolie-Poly model and parameter optimization. This toolbox is significant to the study of viscoelastic models and provide a template for relative research areas.

Exact scattering eigenstates in double quantum-dot systems with an interdot Coulomb interaction
|
We study a double quantum-dot system which consists of two leads of noninteracting electrons and two quantum dots with an interdot Coulomb interaction. We assume spinless electrons and consider arbitrary complex values of all lead-dot couplings and an interdot coupling. We construct exact many-electron scattering eigenstates whose incident states are free-electronic plane waves in the leads. Due to the interaction, some of the incident plane waves are scattered to two-body and three-body bound states. The binding strength of the many-body bound states is affected by the arrangement of the two quantum dots, by which we observe an interplay of the Coulomb interaction and quantum interference. We can understand the many-body bound states in terms of many-body resonances.

In the footsteps of our previous work \cite{RamatonBoschi} we generalize the Stefan-Boltzmann and Wien's displacement laws for the $ \textrm{AdS}_5 \times {\cal S}^5 $ spacetime, the background of the AdS/CFT correspondence foremost realization. Our results take into account the $ \textrm{AdS}_5 \times {\cal S}^5 $ full dimensionality in the electromagnetic field $A^{\mu}$ wave equation, which yields the higher-dimensional blackbody characteristic features suggested in literature. In particular, the total radiated power and the spectral radiancy match the original Stefan-Boltzmann and Wien's displacement laws in the low-energy regime up to available experimental data.

Template-Based Geometric Simulation of Flexible Frameworks

Specialised modelling and simulation methods implementing simplified physical models are valuable generators of insight. Template-based geometric simulation is a specialised method for modelling flexible framework structures made up of rigid units. We review the background, development and implementation of the method, and its applications to the study of framework materials such as zeolites and perovskites. The “flexibility window” property of zeolite frameworks is a particularly significant discovery made using geometric simulation. Software implementing geometric simulation of framework materials, “GASP”, is freely available to researchers.

Quantitative lymphoscintigraphy for detection of metastases to the internal mammary lymph nodes. Biokinetics of 99Tcm-sulphur colloid uptake and correlation with microscopy.

Dymanic quantitative activity determination and accurate scintigraphic localization of parasternal lymph nodes were obtained from antero-posterior measurements with a scintillation camera. The scintigraphic observations were compared with microscopy of the nodes removed at operation. The 99Tcm-sulphur colloid indicated a high frequency (7/16) of absent uptake in normal lymph nodes. However, the technique used indicates that a similar technique with smaller particle size may be a useful method for proper classification of the clinical stage of carcinoma of the breast.

We review some of the recent development in quantum Monte Carlo (QMC) methods for models of strongly correlated electron systems. QMC is a promising general theoretical tool to study many-body systems, and has been widely applied in areas spanning condensed-matter, high-energy, and nuclear physics. Recent progress has included two new methods, the ground-state and finite-temperature constrained path Monte Carlo methods. These methods significantly improve the capability of numerical approaches to lattice models of correlated electron systems. They allow calculations without any decay of the sign, making possible calculations for large system sizes and low temperatures. The methods are approximate. Benchmark calculations show that accurate results on energy and correlation functions can be obtained. This chapter gives a pedagogical introduction to quantum Monte Carlo, with a focus on the constrained path Monte Carlo methods.

Corrections to the collision term in the BGK Boltzmann equation
|
With the discrete method of the hexagonal cell and three different velocities of particle population in each cell, a two-dimensional lattice Boltzmann model is developed in this paper. The collision operator in the Boltzmann equation is expanded to fourth order using the Taylor expansion. With this model, good results have been obtained from the numerical simulation of the reflection phenomenon of the shock wave on the surface of an obstacle and the numerical stability is also good. Thus the applicability of the D2Q19 model is verified.

Accelerated Particles in an AVF Cyclotron with a One or a Two Dee System
|
A general analytical theory is given, describing the motion of accelerated particles in an AVF cyclotron with a one or a two Dee-system. A Hamiltonian is formulated for the horizontal motion of these particles. Especially on the first turns, where the energy gain per turn is not small with respect to the particle energy, the structure of the Dees has much influence. For high harmonic acceleration, the motion in the radial phase space may even become unstable. A coupling exists between radial and longitudinal motion. In a few examples the applicability of the formulated theory is illustrated.

In this paper we study the multivariate ANOVA decomposition for $1$-periodic functions on the torus. In particular we use the integral projection operator that leads to the classical ANOVA decomposition. Relationships between the Fourier coefficients of the function and its ANOVA terms lead to special frequency index sets and give an understanding of the decomposition working in the frequency domain. Moreover, we consider the truncated ANOVA decomposition and provide error bounds for approximation in $\mathrm{L}_\infty$ and $\mathrm{L}_2$. We present an approximation method based on the truncated decomposition with regard to a superposition dimension $d_s$.

Numerical computation of ε-entropy for parabolic equations with analytic solutions
|
Abstract We report on numerical experiments computing the e -entropy for parabolic partial differential equations. The e -entropy is a measure of the spatial density of complexity for the dynamics on an invariant set in function space and has been studied analytically by a number of authors. The e -entropy only requires solutions of the equation to the accuracy of the parameter e and the resulting number is (asymptotically) independent of domain size. We consider the complex Ginzburg–Landau equation as an example where a number of analytic results exist and the Kuramoto–Sivashinsky equation where the accompanying theory has yet to be fully developed. Our numerical results for the Kuramoto–Sivashinsky equation do not contradict the conjectured linear scaling of the dimension with domain size.

Uniform observability of the wave equation via a discrete Ingham inequality
|
In this paper we prove a discrete version of the classical Ingham inequality for nonharmonic Fourier series whose exponents satisfy a gap condition. Time integrals are replaced by discrete sums on a discrete mesh. We prove that, as the mesh becomes finer and finer, the limit of the discrete Ingham inequality is the classical continuous one. This analysis is partially motivated by control-theoretical applications. As an application we analyze the observation properties of numerical approximation schemes of the 1-d wave equation. The discrete Ingham inequality provides observability (and controllability) results which are uniform with respect to the mesh size in suitable classes of numerical solutions in which the high frequency components have been filtered. We also discuss the optimality of these results in connection with the dispersion diagrams of the considered numerical schemes.

An explicit P1 finite element scheme for Maxwell's equations with constant permittivity in a boundary neighborhood
|
This paper is devoted to the complete convergence study of the finite-element approximation of Maxwell's equations in the case where the magnetic permeability is constant. Standard linear finite elements for the space discretization are combined with a well-known explicit finite-difference scheme for the time discretization. The analysis applies to the particular case where the dielectric permittivity has a constant value outside a sub-domain, whose closure does not intersect the boundary of the problem-definition domain. Optimal convergence results are established in natural norms under reasonable assumptions, provided a classical CFL condition holds.

A discrete model of the dynamic behavior of the cardiac muscle
|
The objective of this study is to construct a discrete finite state model of the electrical activity of the heart, which is directly related to the FitzHugh-Nagumo equations, but offers both a faster and more stable solution. The authors set up a 2D two variable model with non-nearest neighbor interactions to include curvature dependence of the wave front. For better approximation of the electrotonic propagation, a hexagonal grid and distance-dependent weighting coefficients are used. Despite its simplicity the model follows the local dynamics prescribed by the modified FitzHugh-Nagumo equations and its parameters are directly derived from the original ones. The model was validated by comparison to existing experimental data for the propagation velocity, curvature velocity relationship, rotation speed and core size. It was successfully used to study spiral wave interactions with nonexcitable obstacles of different shapes.

Abstract The variational Monte Carlo (VMC) method, which evaluates multi-dimensional integrals by random walk sampling based on the Metropolis algorithm, has been implemented in the connected moments expansion (CMX). The Hartree-Fock single determinant multiplied by the Jastrow function has been employed for a trial function. Pilot calculations on the hydrogen molecule at various internuclear separations have been performed. The results are found to be in good agreement with those by Kolos and Wolniewicz.

A Simple Technique for the Monte Carlo Simulation of Transport in Quantum Wells
|
A simple technique that can be implemented in the Monte Carlo (MC) simulation of transport in a quantum well is reported. The main difference between the proposed technique and existing methods is the use of three dimension momentum (3Dk) particles in the simulation of a quantum region. The use of 3Dk particles within a quantum well structure facilitates the MC simulation of transport in nanoscale devices which contain both the classical and quantum regions.

A spectrally formulated finite element for analysis of wave propagation in layered composite media
|
Publisher Summary ::: Wave propagation in asymmetrically stacked composite laminate, because of high frequency impact loading, is studied using a new spectral finite element (SFE) formulation. This novel element is developed using matrix methodology similar to finite element (FE) formulation and has an exact dynamic stiffness matrix, obtained by exactly solving the governing Navier equation in the frequency-domain. As the mass distribution is modeled exactly, the element gives the exact frequency response of each layer. Thus, one element may be as large as one complete layer; and as a result, the system size is nominal compared to the conventional FE system sizes. The fast-Fourier transform (FFT) and Fourier series are used for inversion to the time/space domain. The element captures the essential wave propagation phenomena successfully and demonstrates Rayleigh wave in the surface and Stoneley wave in composite layer interfaces.

A Total Variation Diminishing-Projection Method for Solving Implicit Numerical Schemes for Scalar Conservation Laws
|
The stability of Newton's method applied to implicit numerical schemes for scalar conservation laws requires, in the general case, an upper bound on the size of the timesteps. A simple locally defined projection, a total variation diminishing (TVD)-projection, is introduced, and it is used to obtain always-stable extensions of Newton's method. A numerical study of this method applied to Godunov's implicit scheme is presented.

A brief overview is presented of the VAMAS Surface Chemical Analysis Technical Working Party project. This project is aimed at providing the reference working base for surface analysis. There are currently 20 projects covering AES, XPS, SIMS, sputtered neutral mass spectrometry and sputter-depth profiling. The coordination of the projects leads to considerable gains in confidence and in project output, together with a reduction in the workload necessary to meet the project targets. This arises simply because of the increased availability of characterized samples, reference methodologies and software within the overall programme. This Technical Working Party has been active for 4 years now and definitive milestones are being achieved that would be impossible without the overall coordination.

Accurate broadband RLCG-parameter extraction with TRL calibration
|
In this paper we analyze the impact of systematic errors in TRL calibration on the extracted equivalent circuit parameters of the measured device. We mainly focus on extraction of RLCG-parameters (resistance, inductance, capacitance, conductance) of transmission lines and inductors. We show how the uncertainties in measured S-parameters and in determined characteristic impedance propagate into RLCG-parameters. In particular, we emphasize the importance and the difficulty of an accurate determination of the imaginary part of characteristic impedance. We use the results of our sensitivity analysis to estimate the accuracy of RLCG-parameter extraction of a coplanar transmission line and a 2.2 nH spiral inductor. Finally, we propose an alternative method for determination of certain RLCG-parameters based on causal relationships.

It is extended here in explicit dynamics and used in order to link a zone showing ruptures by fragmentation meshed with Smoothed Particles Hydrodynamics (SPH) and a larger second undamaged one meshed with finite elements (FEM). This paper gives some details on the method implemented in the EUROPLEXUS code, its validation on simple benchmarks and a confrontation between numerical simulations and results of an experimental study of concrete slab resistance to projectile impacts.

The specification of non-functional requirements, e. g., on timing forms an essential part of modern system design. Modeling languages such as MARTE/CCSL provide dedicated description means enabling engineers to formally define the ticking of the clocks to be implemented in terms of clock constraints and the actually intended timing behavior in terms of instant relations. But thus far, instant relations have only been utilized in order to monitor the correct execution of the clock constraints. In this work, we propose a methodology which, for the first time, verifies clock constraints against the given instant relations. To this end, the timing behavior is represented in terms of an automaton followed by its verification through satisfiability solvers. A case study illustrates the application of the proposed methodology.

Gluon depletion and J/psi suppression in pA collisions
|
The gluon distribution of a nucleon propagating through a nucleus can change depending on how far the penetration depth is. It is a nonperturbative process that we describe by an evolution equation. The kernel of the integral equation is to be determined by a phenomenological study of J/psi suppression in pA collision. The data of E866 on alpha(x_F) shows significant dependence on x_F at large x_F. It presents a feature that has not been explained by any hadronic absorption model. We show that gluon depletion is a simple mechanism that can account for it. The result has far-reaching implications on the role of partons in nuclear collisions.

Transport coefficients of quantum plasma.

The two time Green's function method is applied to calculate the transport coefficients of an electron gas. The sequence of equations for Green's functions is derived. and it is shown that the results corresponding to the random phase approximation (including the exchange effects) can be obtained by terminating this sequence at the first stage. Proceeding to the second stage, one can quite naturally take the shielding effects and the plasma oscillation into account. Some discussions are made about the derivation of the kinetic equation for quantum plasma. (auth)

The generation and behavior of the fractal Koch array factor from a Kaiser window generator is studied. The main advantage of using Kaiser windows is that pattern parameters become much more flexible through altering the Kaiser window. The mainlobe width, current distribution, side-lobe ratio are now adjustable. Different reduced array structures can be obtained by using different threshold levels. Higher threshold values result in a highly reduced number of elements but they may highly distort the pattern and, hence, the multiband behavior. Finally, we study the effect of quantization of the feeding values. Quantization is necessary for implementation and simplification purposes. Several configurations of current distributions with the corresponding patterns are illustrated for different quantization levels. It is shown that moderate quantization keeps the same interesting similarity properties at several bands.

Model for Coupled Large-Strain Consolidation and Solute Transport under Constant Rate of Strain
|
A numerical model, called CSTCRS1, is presented for coupled onedimensional large strain consolidation and solute transport under constant rate of strain (CRS) loading conditions. The model is based on a dual-Lagrangian framework that tracks separately the motions of fluid and solid phases. A series of numerical simulations indicates that transport boundary conditions can have an important effect on the solute transport during CRS consolidation. The zero concentration boundary condition yielded the largest solute mass outflows, the reservoir boundary condition yielded intermediate values, and the zero concentration gradient boundary condition yielded the smallest outflows. Additional simulations indicate that, for conditions considered, increasing the applied strain rate will generally decrease solute mass outflow.

Spatial behavior analysis at the global level using fractal geometry.

Previous work has suggested that an estimate of fractal dimension can provide a useful metric for quantifying settlement patterns. This study uses fractal methods to investigate settlement patterns at a global scale showing that the scaling behavior of the pattern of the world's largest cities corresponds to that typically observed for coastlines and rivers. This serves to validate the use of fractal dimension as a scale-independent measure of settlement patterns which can be correlated with other physical features. Such a measure may be a useful validation criterion for models of human settlement and spatial behavior.

The diffraction profile and its moments are obtained for particle-size broadening, the expressions being `exact' in the kinematic approximation for crystals of simple shapes (parallelepiped, tetrahedron, octahedron, sphere). A further term in the variance-range curve is obtained, depending on Mitra's parameter 34, for which the name `rotundity parameter' is proposed. The effect of a distribution of particle sizes is discussed; the Scherrer constant and the taper parameter are affected in a way already known, and M is unaffected.

ABSTRACT This paper introduces a new p-regions model called the Network-Max-P-Regions (NMPR) model. The NMPR is a regionalization model that aims to aggregate n areas into the maximum number of regions (max-p) that satisfy a threshold constraint and to minimize the heterogeneity while taking into account the influence of a street network. The exact formulation of the NMPR is presented, and a heuristic solution is proposed to effectively compute the near-optimized partitions in several simulation datasets and a case study in Wuhan, China.

This paper considers corona discharge problems with multiple conductors, such as those appearing in some electrostatic precipitators. A common precise condition is identified in which the previous approaches proposed in the literature fail. For dealing with these conditions, a novel, stabilized, and regularized formulation of the problem is proposed. Moreover, a Newton–Raphson scheme is defined for iteratively solving a nonstandard Petrov–Galerkin finite-element discretization of the problem. The presented approach is validated on a benchmark for which an analytical solution is known and its applicability to problems of industrial relevance is shown.

Reliability of a cascade system with normal stress and exponential strength

In this paper we study the reliability of an N-cascade system whose stress and strength follow normal and exponential distributions, respectively. In this system we can observe that reliability increases for lower values of strength parameter (λ) and stress parameter (μ). Marginal reliability rate also increases at higher values of λ. Hence we conclude that the addition of components by a cascade system gives a significant improvement.

We discuss the role of quantum chaos in atomic nuclei. After reviewing the basic assumptions of the nuclear shell model, we analyze the spectral statistics of the energy levels obtained with realistic shell-model calculations in the fp shell. In particular, for Ca isotopes we observe a transition from order to chaos by increasing the excitation energy and a clear quantum signature of the breaking of integrability by changing the single-particle spacings.

The growing interest in ferrofluid bearings is caused by their excellent self-sealing ability. The understanding of behaviour of ferrofluid film boundary adjacent to ambient air is crucial for the proper design of the sealing unit of ferrofluid bearings. This paper is the first attempt to predict the shape of a ferrofluid free boundary in the presence of a static load and magnetic field. Analysis involves simultaneous integration of the Reynolds equation and the free boundary equation using perturbation technique with respect to shaft eccentricity.

Due to their high aspect ratio, magnetic nanowires are interesting for various applications. Fe nanowires are of particular interest due to their high magnetization, which suggests high shape anisotropy is possible. Here, we show how the electrodeposition process can be adapted to the constraints of a high aspect ratio template in order to approach an ideal behaviour of smooth and pure Fe nanowires. An adjustment of the Fe 2+ concentration and the addition of H 3 BO 3 result in smooth and continuous nanowires; saturation polarization is achieved, together with an anisotropy field of up to 70% compared to pure Fe. Mossbauer spectroscopy reveals a negligible amount of impurities. Together with magnetic measurements we show that shape anisotropy aligns the preferential magnetization axis along the wire axis.

Using magnetic measurements structural irregularities in electrodeposited nanotubes are inferred. The correlation between morphology and magnetic properties is very useful for studying materials. Through the use of the magnetic switching field distribution, the association with the surface irregularities imperfections of the magnetic nanotubes was performed. The distribution of magnetic switching field presents well behaved in smooth-surface nanotubes and, for nanotubes with irregularities, the distribution of switching fields has a noisy behavior, added to that smoothed signal. This noise is due to the superficial irregularities on the tubes surface because the magnetic barriers occurring in imperfect structures. Pinning centers due to irregularities are the principal aspect to observe in this situation. Magnetic measurements were associated directly to the morphology obtained by scanning electron microscopy.

Towards an electro-magnetic field separation of deposited material implemented in an ion beam sputter process
|
Nowadays, Ion Beam Sputter (IBS) processes are very well optimized on an empirical basis. To achieve further progresses, a modification of the IBS process by guiding the coating material using an axial magnetic field and an additional electrical field has been studied. The electro-magnetic (EM) field leads to a significant change in plasma properties and deposition rate distributions, whereas an increase in deposition rate along the centerline of the axial EM field around 150% was observed. These fundamental studies on the prototype are the basis for the development of an applicable and workable design of a separation device.

Freehand 3D ultrasound imaging system using electromagnetic tracking
|
Ultrasound imaging is a non-invasive, real-time, low-cost, effective imaging modality for diagnosing and managing a variety of diseases. Most ultrasound-based clinical procedures are performed using conventional two-dimensional (2D) ultrasound images. However, accurate visualization and analysis of the three-dimensional (3D) anatomy using a sequence of 2D ultrasound images is often challenging. To overcome this challenge, several approaches have been proposed for 3D ultrasound imaging. This study contributes to these ongoing efforts by describing a freehand 3D ultrasound imaging system based on a conventional 2D ultrasound machine and a 3D electromagnetic tracking system. The synthesized 3D ultrasound volumes are visualized using the Visualization Toolkit (VTK) open-source library and the ParaView open-source application. The feasibility of our freehand 3D ultrasound imaging system is demonstrated by imaging a double cross-wire phantom.

Dependence on the prior magnetic map become one of the key problems which restrict the development of the geomagnetic navigation. This paper inspired from the animal navigation behavior which dispense with the priori geomagnetic map. First, we generalize the bio-inspired navigation process as a multi-objective problems. Then, present a stress evolution search AUV navigation model for the particularity of geomagnetic navigation, which make multi-objective problem solving search combine with navigation movement to achieve the purpose of navigation. Finally, compared the present model with a gradient descent model with part priori geomagnetic map. The simulation results show that the proposed algorithm allows the AUV to navigate efficiently using geomagnetic information without prior map. The proposed algorithm offers insights into the research and application of the biologically inspired geomagnetic navigation.

what does soft magnetism mean
|
Hard Magnetic Materials. Soft Magnetic Materials. 1. Materials which retain their magnetism and are difficult to demagnetize are called hard magnetic materials. These materials retain their magnetism even after the removal of the applied magnetic field. Hence these materials are used for making permanent magnets.n permanent magnets the movement of the domain wall is prevented. They are prepared by heating the magnetic materials to the required temperature and then quenching them. Impurities increase the strength of hard magnetic materials. Soft magnetic materials are easy to magnetize and demagnetize.

EFFECT OF AN ISOLATE FROM GYMNEMA SYLVESTRE, R. BR. IN THE CONTROL OF DIABETES MELLITUS AND THE ASSOCIATED PATHOLOGICAL CHANGES
|
Gymnema sylvestre, R. Br., popularly known as Meshashringi in Sanskrit and Sarkaraikolli in Tamil, was investigated for the control of type I (insulin dependent) diabetes in experimental animals. The hypoglycaemic extract was found to bring about blood glucose homeostasis, by increasing serum insulin levels. The islets of langerhans appear to be restored or regulated by the herbal extract. Increased glycoprotein, which is the major metabolic abnormality in diabetes mellitus and the resultant nephropathy, retinopathy and micro and macroangiopathy, is brought under control by the administration of the leaf extract.

Impact of Double-Row Height Standard Cells on Placement and Routing
|
In this article we propose a systematic method to study how increasing use of double-row height cells would impact placement and routability of a circuit. To facilitate our study, we handcraft 87 standard cells, each of which has two layouts of the same area, one designed with single-row height and the other designed with double-row height. Experimental results show that the compromise made by placement, later turned into routability degradation, for handling double-row height cells reaches its peak when a circuit has about 30% of the cells being double-row height cells if placement is done with a core utilization of 90%. It is about 40% if a core utilization of 80% is employed.

SPONTANEOUS INTRACRANIAL HYPOTENSION
|
Spontaneous intracranial hypotension (SIH) is uncommon and usually undiagnosed entity which present most commonly with postural headache. The diagnosis is difficult because of the nonspecific symptoms and lack of awareness about the disease .It is important to recognize SIH as if the disease goes undiagnosed it can cause a significant delay in initiation of the treatment and exposing patient to the risks associated with the treatment for the disorders mimicking intracranial hypotension . We describe a patient with SIH and outline the important clinical and radiological features of this syndrome. The aim of presenting this case report is to emphasize the need for being vigilant for this rare disorder which should be considered in the differential diagnosis of recurrent posture related headache.
