The properties of fully flexible Lennard-Jones chains in the solid phase: Wertheim theory and simulation
Creators: name: Sanz, Eduardo

Publisher: name: arXiv
Year: 2009
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: NpT ensemble Monte Carlo simulations were performed for fully flexible Lennard-Jones chains in the solid phase. The bond length between monomers within the chains is fixed to $L=σ$ and the molecule is free to adopt any configuration. The solid structure of fully flexible chains is obtained by randomly locating the bonds of the chain within a face centered cubic close packed arrangement of atoms. For fully flexible chains it is believed that the stable solid phase is disordered. Such a solid is considered in this work. Computer simulations were performed for chains with $m=3, 4$ and 5 monomer units, and results were obtained for the equation of state and internal energy of the chains. An extension of Wertheim's TPT1 to the solid phase of Lennard-Jones chains (C.Vega, F.J.Blas and A.Galindo, J.Chem.Phys.,{\bf 116},7645,2002) has been proposed recently. The simulation results of this work provide a check on the performance of this theory. It is found that Wertheim's TPT1 successfully predicts the equation of state and internal energies of fully flexible LJ chains in the solid phase. Finally, a rigid LJ chain in a linear configuration has been considered. Computer simulations were also performed for the rigid chain in an ordered solid structure. It is found that fully flexible and linear rigid chains present quite different equations of state and different thermodynamic properties in the solid phase.

Small Business Loans Act
Creators: name: Dewhirst, Gordon Hedley
Publisher: name: University of British Columbia
Year: 2012

description: The Small Businesses Loans Act was designed to increase the flow of funds for capital purposes from the banking system to small firms in the Canadian economy. This study examines the need for this legislation. The major sources of funds for small business are discussed and the question of the adequacy of these financing facilities is considered. This part of the study concludes that the 'MacMillan Gap' in Canada has been narrowed in the post-war period, but not yet closed. The study then examines the effectiveness of the Small Businesses Loans Act in bridging the remaining gap. The legislation, and the record of borrowing under the Act are reviewed. Particular attention is directed to the effects of monetary policy on the volume of lending under this Act. The study also includes an examination of the experience of a sample of borrowers, their characteristics, the purposes for which loans were obtained and banking practices with respect to this lending program. The conclusions of the study suggest that the Small Businesses Loans Act has fulfilled a useful role in improving the financial facilities available to small business despite a number of deficiencies in the legislation. It is also suggested however that the need for this legislation has largely been removed by recent amendments to the Bank Act.

CAMOT: Camera Angle-aware Multi-Object Tracking

description: This paper proposes CAMOT, a simple camera angle estimator for multi-object tracking to tackle two problems: 1) occlusion and 2) inaccurate distance estimation in the depth direction. Under the assumption that multiple objects are located on a flat plane in each video frame, CAMOT estimates the camera angle using object detection. In addition, it gives the depth of each object, enabling pseudo-3D MOT. We evaluated its performance by adding it to various 2D MOT methods on the MOT17 and MOT20 datasets and confirmed its effectiveness. Applying CAMOT to ByteTrack, we obtained 63.8% HOTA, 80.6% MOTA, and 78.5% IDF1 in MOT17, which are state-of-the-art results. Its computational cost is significantly lower than the existing deep-learning-based depth estimators for tracking.

description: In this work we present scanning Fabry-Perot H$α$ observations of the isolated interacting galaxy pair NGC 5278/79 obtained with the PUMA Fabry-Perot interferometer. We derived velocity fields and rotation curves for both galaxies. For NGC 5278 we also obtained the residual velocity map to investigate the non-circular motions, and estimated its mass by fitting the rotation curve with a disk+halo components. We test three different types of halo (pseudo-isothermal, Hernquist and Navarro Frenk White) and obtain satisfactory fits to the rotation curve for all profiles. The amount of dark matter required by pseudo-isothermal profile is about ten times smaller than, that for the other two halo distributions. Finally, our kinematical results together with the analysis of dust lanes distribution and of surface brightness profiles along the minor axis allowed us to determine univocally that both components of the interacting pair are trailing spirals.

description: Chiral gauge theories can be defined in four-dimensional Anti de Sitter space, but AdS boundary conditions explicitly break the chiral symmetry in a specific, well defined manner, which in turns results in an anomalous Ward identity. When the 4D theory admits a dual description in terms of a 3D CFT, the 3D dual of the broken chiral symmetry is a certain double-trace deformation of the CFT, which produces the same anomalous chiral Ward identities that obtains in the 4D bulk theory.

description: We have prepared the newly discovered Fe-based superconducting material $\rm LaO_{1-x}F_xFeAs$ ($0\leq x\leq 0.2$) in polycrystalline form and have investigated the samples by means of structural, thermodynamic and transport measurements. Our investigations reveal a non superconducting phase at $0\leq x\lesssim0.04$ which for $x=0$ is characterized by a structural transition towards an orthorhombic distortion at $T_s\approx 160$ K and antiferromagnetic spin order at $T_N\approx138$ K. Both transitions lead to strong anomalies in various transport properties as well as in magnetization and in specific heat. Remarkably, the transition temperatures are only weakly doping dependent up $x\lesssim 0.04$. However, the transitions are abruptly suppressed at $x\geq0.05$ in favour of a superconducting phase with a critical temperature $T_c\gtrsim 20$ K. Upon further increasing the F-doping $T_c$ increases up to a maximum of $T_c=26.8$ K at $x=0.1$ which is followed by a decrease down to $T_c\approx10$ K at $x\geq0.15$.

description: We introduce density dependence of the cell size in cellular-automaton models for traffic flow, which allows a more precise correspondence between real-world phenomena and what observed in simulation. Also, we give an explicit calibration of the particle density particularly for the asymmetric simple exclusion process with some update rules. We thus find that the present method is valid in that it reproduces a realistic flow-density diagram.

description: Seshadri constants were defined by Demailly around 30 years ago using the ampleness criterion of Seshadri. Demailly was interested in studying problems related to separation of jets of line bundles on projective varieties, specifically in the context of the well-known Fujita Conjecture. However, Seshadri constants turned out to be objects of fundamental importance in the study of positivity of linear series and many other areas. Consequently, in the past three decades, they have become a central object of study in numerous directions in algebraic geometry and commutative algebra. In this mini-workshop, we studied some of the most interesting current research problems concerning Seshadri constants. We expect that this exploration will help focus research on some of the most important questions in this area in the years to come.
Privacy-Preserving Redaction of Diagnosis Data through Source Code Analysis

description: Protecting sensitive information in diagnostic data such as logs, is a critical concern in the industrial software diagnosis and debugging process. While there are many tools developed to automatically redact the logs for identifying and removing sensitive information, they have severe limitations which can cause either over redaction and loss of critical diagnostic information (false positives), or disclosure of sensitive information (false negatives), or both. To address the problem, in this paper, we argue for a source code analysis approach for log redaction. To identify a log message containing sensitive information, our method locates the corresponding log statement in the source code with logger code augmentation, and checks if the log statement outputs data from sensitive sources by using the data flow graph built from the source code. Appropriate redaction rules are further applied depending on the sensitiveness of the data sources to preserve the privacy information in the logs. We conducted experimental evaluation and comparison with other popular baselines. The results demonstrate that our approach can significantly improve the detection precision of the sensitive information and reduce both false positives and negatives.
Design and testing of time-varying inductors and capcitors for an electrical speech synthesizer
Creators: name: Wickwire, Kenneth Freeman
Publisher: name: University of British Columbia
Year: 2011

description: This thesis describes the design and testing of time-varying inductors and capacitors for use in an electrical analogue of the human vocal tract. The inductors and capacitors were varied in accordance with an external control signal by varying the value of a resistor in a circuit which used operational amplifiers to simulate a variable impedance. The inductor actually tested is not a true inductor, since its voltage e and current i are related by the equation [formula omitted], where L(t) is an externally controlled time function. A device for which [formula omitted] will probably be adequate for use in a vocal tract analogue. A true inductor for which [formula omitted] can be realized by making a change in the circuit tested. For the inductor tested, the maximum allowable input voltage and current are ± 2 volts and ± 2 ma, respectively. For the capacitor, the allowable ranges are ± 4 volts and ± 20 ma. The inductance and capacitance can be varied over a range of 250:1 with good linearity with respect to external control voltage and audio frequency. The inductor's Q exceeds 50 and the capacitor's Q exceeds 200 for all frequencies between 200 Hz and 5 KHz. A system for routing control signals from a digital computer to the vocal tract analogue has been devised. Each component in the analogue is to be serviced by the computer at discrete time intervals. Between computer service times, the value of each component is interpolated by the up-down counter-digital comparator interpolating system described in the thesis.

description: We identify a duality transformation in one-dimensional hopping models that relates propagators in general disordered potentials linked by an up-down inversion of the energy landscape. This significantly generalises previous results for a duality between trap and barrier models. We use the resulting insights into the symmetries of these models to develop a real-space renormalisation scheme that can be implemented computationally and allows rather accurate prediction of propagation in these models. We also discuss the relation of this renormalisation scheme to earlier analytical treatments.

description: Nuclear disks and rings are frequent galaxy substructures, for a wide range of morphological types (from S0 to Sc). We have investigated the possible minor-merger origin of inner disks and rings in spiral galaxies through collisionless N-body simulations. The models confirm that minor mergers can drive the formation of thin, kinematically-cold structures in the center of galaxies out of satellite material, without requiring the previous formation of a bar. Satellite core particles tend to be deposited in circular orbits in the central potential, due to the strong circularization experienced by the satellite orbit through dynamical friction. The material of the satellite core reaches the remnant center if satellites are dense or massive, building up a thin inner disk; whereas it is fully disrupted before reaching the center in the case of low-mass satellites, creating an inner ring instead.

Random Matrices

Publisher: name: Zürich : EMS Publ. House
Year: 2019
Subjects: subject: Konferenzschrift
subject: 510

description: Large complex systems tend to develop universal patterns that often represent their essential characteristics. For example, the cumulative effects of independent or weakly dependent random variables often yield the Gaussian universality class via the central limit theorem. For non-commutative random variables, e.g. matrices, the Gaussian behavior is often replaced by another universality class, commonly called random matrix statistics. Nearby eigenvalues are strongly correlated, and, remarkably, their correlation structure is universal, depending only on the symmetry type of the matrix. Even more surprisingly, this feature is not restricted to matrices; in fact Eugene Wigner, the pioneer of the field, discovered in the 1950s that distributions of the gaps between energy levels of complicated quantum systems universally follow the same random matrix statistics. This claim has never been rigorously proved for any realistic physical system but experimental data and extensive numerics leave no doubt as to its correctness. Since then random matrices have proved to be extremely useful phenomenological models in a wide range of applications beyond quantum physics that include number theory, statistics, neuroscience, population dynamics, wireless communication and mathematical finance. The ubiquity of random matrices in natural sciences is still a mystery, but recent years have witnessed a breakthrough in the mathematical description of the statistical structure of their spectrum. Random matrices and closely related areas such as log-gases have become an extremely active research area in probability theory. This workshop brought together outstanding researchers from a variety of mathematical backgrounds whose areas of research are linked to random matrices. While there are strong links between their motivations, the techniques used by these researchers span a large swath of mathematics, ranging from purely algebraic techniques to stochastic analysis, classical probability theory, operator algebra, supersymmetry, orthogonal polynomials, etc.

description: AbstractThe importance of research data has grown as researchers across disciplines seek to ensure reproducibility, facilitate data reuse, and acknowledge data as a valuable scholarly commodity. Researchers are under increasing pressure to share their data for validation and reuse. Adopting good data management practices allows researchers to efficiently locate their data, understand it, and use it throughout all of the stages of a project and in the future. Additionally, good data management can streamline data analysis, visualization, and reporting, thus making publication less stressful and time-consuming. By implementing foundational practices of data management, researchers set themselves up for success by formalizing processes and reducing common errors in data handling, which can free up more time for research. This paper provides an introduction to best practices for managing all types of data.
Moist Processes in the Atmosphere

Publisher: name: Zürich : EMS Publ. House
Year: 2019
Subjects: subject: Konferenzschrift
subject: 510

description: Processes related to water in the atmosphere lead to severe uncertainties in weather forecasting and climate research. Atmospheric water vapor and cloud water strongly influence the Earth's energy budget through, e.g., energy conversions associated with phase changes, fluid dynamical effects associated with buoyancy, and through their influence on radiative transfer properties of the atmosphere. Given the critical green-house effect of water vapor, it seems astounding that climate modellers cannot with certainty state whether the Earth's cloud system has a positive or negative influence on the global mean temperature. The formation of clouds involves small-scale processes currently unresolved by climate models, and thus cloud cover is one of the main sources of uncertainty. This large uncertainty has its roots in the extremely wide range of length and time scales associated with moist processes, which pose an equally wide range of challenges to mathematical and computational modelling. New and innovative methods, modeling frameworks, efficient computational techniques, and complex statistical data analysis procedures as well as their mathematical analysis are urgently needed in order to make progress in this new field -- from the mathematicians point of view. One of the main goals of this workshop is to show the path forward for current and future applied mathematical scientists, to work hand in hand across the disciplines of mathematics, physics, and atmospheric science, in order to tackle the complex problem of dynamical and thermodynamical processes associated with clouds and moisture, both from the theoretical and the applied view points.

Publisher: name: University of British Columbia
Year: 2011

description: A study is made of some of the existing techniques for determining the positions and excitations of the elements in an array, in order to produce a desired radiation pattern. A new method based on numerical quadrature is proposed. Equal-sidelobe patterns are synthesized and a comparison of the methods is made on this basis. Results indicate that the proposed quadrature method is an improvement over the other tested methods in two ways, (i) it produces a more accurately synthesized pattern and (ii) it is simple to compute. It is therefore useful for synthesizing arrays containing large numbers of elements. However, for the particular radiation pattern selected, none of the methods gave an improvement over the corresponding uniformly-spaced array.

description: Accurate MS2 spectrum predictions enable drastic improvements in peptide identification workflows. This identification improvement is particularly useful for challenging proteomics experiments where conventional identification software often falls short. Notable examples of such cases are proteogenomics, data independent acquisition, and open modification searches. The latter also implicitly requires models that can account for residue modifications, but current state-of-the-art MS2 spectrum predictors cannot take these into account. Instead, the corresponding mass shift is introduced, and peak intensities are simply presumed to remain the same for modified and unmodified forms. We here therefore introduce a novel peptide spectrum predictor, called MS²DIP, which can provide accurate predictions for peptides carrying residue modifications, including for modifications not seen during training.

 Immunopeptidomics aims to identify immunopeptides, which are presented on major histocompatibility complexes. Existing immunopeptidomics data analysis pipelines have some major hurdles to overcome, which complicates their identification. To enable
 MS²PIP-based rescoring of immunopeptide PSMs, we have retrained MS²PIP for non-tryptic peptides. Next, the new MS²PIP models, DeepLC, and Percolator were integrated into one software package, called MS²Rescore. Using this integration, we could identify 46% more spectra and 36% more unique peptides at 1% false discovery rate. The integration of the new immunopeptide MS²PIP models, DeepLC, and Percolator into MS²Rescore shows great promise to substantially improve the identification of novel neo- and xeno-epitopes in existing immunopeptidomics workflows.

Year: 2019
Subjects: subject: Konferenzschrift
subject: 510

description: Nonlinear elastodynamics sets a plethora of challenging mathematical problems such as those concerning wave propagation in solids. Elastic vibrations and acoustic waves have been widely studied because of their applications in nondestructive tests of materials and structures, and, in recent times, several novel aspects of the theory of wave propagation in solids have blossomed thanks to the introduction of metamaterials and new technological devices. The goal of this workshop was to bring together researchers with different backgrounds to discuss recent advances, and to stimulate future work.
Factorization of quantum charge transport for non-interacting fermions

description: We show that the statistics of the charge transfer of non-interacting fermions through a two-lead contact is generalized binomial, at any temperature and for any form of the scattering matrix: an arbitrary charge-transfer process can be decomposed into independent single-particle events. This result generalizes previous studies of adiabatic pumping at zero temperature and of transport induced by bias voltage.

Mini-Workshop: Superpotentials in Algebra and Geometry

Year: 2020
Subjects: subject: Konferenzschrift

description: Mirror symmetry has been at the epicenter of many mathematical discoveries in the past twenty years. It was discovered by physicists in the setting of super conformal field theories (SCFTs) associated to closed string theory, mathematically described by $\sigma$-models. These $\sigma$-models turn out in two different ways: the A-model and the B-model. Physical considerations predict that deformations of the SCFT of either $\sigma$-model should be isomorphic. Thus the mirror symmetry conjecture states that the A-model of a particular Calabi-Yau space $X$ must be isomorphic to the B-model of its mirror $\check{X}$. Mirror symmetry has been extended beyond the Calabi-Yau setting, in particular to Fano varieties, using the so called Landau-Ginzburg models. That is a non-compact manifold equipped with a complex valued function called the \emph{superpotential}. In general, there is no clear recipe to construct the mirror for a given variety which demonstrates the need of joining mathematical forces from a wide range. The main aim of this Mini-Workshop was to bring together experts from the different communities (such as symplectic geometry and topology, the theory of cluster varieties, Lie theory and algebraic combinatorics) and to share the state of the art on superpotentials and explore connections between different constructions.
Refinements of the Littlewood-Richardson Rule

description: In the prequel to this paper, we showed how results of Mason involving a new combinatorial formula for polynomials that are now known as Demazure atoms (characters of quotients of Demazure modules, called standard bases by Lascoux and Schutzenberger) could be used to define a new basis for the ring of quasisymmetric functions we call Quasisymmetric Schur functions (QS functions for short). In this paper we develop the combinatorics of these polynomials futher, by showing that the product of a Schur function and a Demazure atom has a positive expansion in terms of Demazure atoms. As a by-product, using the fact that both a QS function and a Demazure character have explicit expressions as a positive sum of atoms, we obtain the expansion of a product of a Schur function with a QS function (Demazure character) as a positive sum of QS functions (Demazure characters). Our formula for the coefficients in the expansion of a product of a Demazure character and a Schur function into Demazure characters is similar to known results and includes in particular the famous Littlewood-Richardson rule for the expansion of a product of Schur functions in terms of the Schur basis.

Mini-Workshop: One-sided and Two-sided Stochastic Descriptions
Creators: name: (:Unkn) Unknown
Publisher: name: Zürich : EMS Publ. House
Year: 2020
Subjects: subject: Konferenzschrift
subject: 510

description: We consider the set of discrete time stochastic processes which are dependent on their past, and the set of those that depend on both their past and their future. As long as we only allow dependence on a finite number of variables, those two sets are the same. However interesting questions appear when the dependence becomes infinite, and some of them were discussed during our mini-workshop.
Design and Analysis of Infectious Disease Studies

description: This was the fifth workshop on mathematical and statistical methods on the transmission of infectious diseases. Building on epidemiologic models which were the subject of earlier workshops, this workshop concentrated on disentangling who infected whom by analysing high-resolution genomic data of pathogens which were routinely collected during disease outbreaks. Following the trail of the small mutations which continuously occur in different places of the pathogens’ genomes, mathematical tools and computational algorithms were used to reconstruct transmission trees and contact networks.
One-Loop Amplitudes in N=4 Super Yang-Mills and Anomalous Dual Conformal Symmetry

description: We discuss what predictions can be made for one-loop superamplitudes in maximally supersymmetric Yang-Mills theory by using anomalous dual conformal symmetry. We show that the anomaly coefficient is a specific combination of two-mass hard and one-mass supercoefficients which appears in the supersymmetric on-shell recursion relations and equals the corresponding tree-level superamplitude. We discuss further novel relations among supercoefficients imposed by the remaining non-anomalous part of the symmetry. In particular, we find that all one-loop supercoefficients, except the four-mass box coefficients, can be expressed as linear combinations of three-mass box coefficients and a particular symmetric combination of two-mass hard coefficients. We check that our equations are explicitly satisfied in the case of one-loop n-point MHV and NMHV amplitudes. As a bonus, we prove the covariance of the NMHV superamplitudes at an arbitrary number of points, extending previous results at n <= 9.
