Year: 2022

description: The aim of this essay is to point out the challenges and opportunities of government export credits and insurance in Europe. The Covid-19 pandemic confronted the entire world with new challenges. This also applied to the export financing and insurance market. Furthermore, there are also challenges that play a major role for ECAs regardless of the pandemic. However, the risks are also offset by opportunities that may enable European export credit agencies to prevail against international competition. The focus of this essay is on the export credit agencies from Finland (Finnvera), Sweden (EKN) and Portugal (COSEC). As part of the European Union (EU) and the Organisation for Economic Co-operation and Development (OECD) the three ECAs share many fundamental similarities but in some points they may also distinguish from each other.

description: We report on the indigenous design and development of laboratory scale travelling heater method (THM) system to grow detector grade Cd0.9Zn0.1Te (CdZnTe) single crystals. THM system mainly consists of two-zone furnace with a tuneable temperature gradient (30 - 80 C/cm), high precision translation (1 - 25 mm per day) and rotation (1 - 50 rpm) assemblies to meet the stringent conditions that are essential to grow detector grade CdZnTe single crystals. Further, a load cell in the THM system enables continuous monitoring of the growth. Systematic growth experiments were performed to optimize the various growth parameters in order to achieve large grain single crystals. Herein, the effect of temperature gradient and growth rate on the increase in grain size is discussed in detail. Each successful growth experiment yields a minimum of four detector grade elements of dimensions 10 x 10 x 5 mm3 from a starting charge of 100 g of CdZnTe. The crystalline nature and quality of the detector elements were evaluated using Laue, NIR transmission spectroscopy and I-V characteristics. Crystals with resistivity greater than ~ 1-10 giga-ohm-cm were identified for testing gamma ray detection. The photo peak of 137Cs was resolved with an energy resolution of 4.2 % at 662 keV and its measured electron mobility lifetime product is found to be ~ 3.3 x 10-3 cm2/V. The demonstration of the gamma ray detection with a relatively high μτ product is the testimony to the successful growth of detector grade CdZnTe single crystals by an indigenously developed THM system.

description: We analyze the effect of a linear time-variation of the interaction strength on a trapped one-dimensional Bose gas confined to an optical lattice. The evolution of different observables such as the experimentally accessible onsite particle distribution are studied as a function of the ramp time using time-dependent exact diagonalization and density-matrix renormalization group techniques. We find that the dynamics of a trapped system typically display two regimes: for long ramp times, the dynamics are governed by density redistribution, while at short ramp times, local dynamics dominate as the evolution is identical to that of an homogeneous system. In the homogeneous limit, we also discuss the non-trivial scaling of the energy absorbed with the ramp time.

description: We present a model of cosmic ray injection into the Galactic space based on recent gamma-ray observations of supernova remnants (SNRs) and pulsar wind nebulae (PWNe) by the Fermi Large Area Telescope and imaging atmospheric Cherenkov telescopes. Steady-state (SS) injection of nuclear particles and electrons (e^-) from the Galactic ensemble of SNRs, and electrons and positrons (e^+) from the Galactic ensemble of PWNe are assumed, with their injection spectra inferred under guidance of gamma-ray observations and recent development of evolution and emission models. The ensembles of SNRs and PWNe are assumed to share the same spatial distributions. Assessment of possible secondary CR contribution from dense molecular clouds interacting with SNRs is also given. CR propagation in the interstellar space is handled by GALPROP. Different underlying source distribution models and Galaxy halo sizes are employed to estimate the systematic uncertainty of the model. We show that this observation-based model reproduces the positron fraction e^+/(e^- + e^+) and antiproton-to-proton ratio reported by Pamela and other previous missions reasonably well, without calling for any speculative sources. A discrepancy remains, however, between the total e^- + e^+ spectrum measured by Fermi and our model below 20GeV, for which the potential causes are discussed. Important quantities for Galactic CRs including their energy injection, average lifetime, and mean gas density along their typical propagation path are also estimated.

description: Here we investigate the phase diagram of the SO(n) bilinear-biquadratic quantum spin chain by studying the global quantum correlations of the ground state. We consider the cases of n=3,4 and 5 and focus on the geometric entanglement in the thermodynamic limit. Apart from capturing all the known phase transitions, our analysis shows a number of novel distinctive behaviors in the phase diagrams which we conjecture to be general and valid for arbitrary n. In particular, we provide an intuitive argument in favor of an infinite entanglement length in the system at a purely-biquadratic point. Our results are also compared to other methods, such as fidelity diagrams.

description: Arnold, Falk, and Winther recently showed [Bull. Amer. Math. Soc. 47 (2010), 281-354] that linear, mixed variational problems, and their numerical approximation by mixed finite element methods, can be studied using the powerful, abstract language of Hilbert complexes. In another recent article [arXiv:1005.4455], we extended the Arnold-Falk-Winther framework by analyzing variational crimes (a la Strang) on Hilbert complexes. In particular, this gave a treatment of finite element exterior calculus on manifolds, generalizing techniques from surface finite element methods and recovering earlier a priori estimates for the Laplace-Beltrami operator on 2- and 3-surfaces, due to Dziuk [Lecture Notes in Math., vol. 1357 (1988), 142-155] and later Demlow [SIAM J. Numer. Anal., 47 (2009), 805-827], as special cases. In the present article, we extend the Hilbert complex framework in a second distinct direction: to the study of semilinear mixed problems. We do this, first, by introducing an operator-theoretic reformulation of the linear mixed problem, so that the semilinear problem can be expressed as an abstract Hammerstein equation. This allows us to obtain, for semilinear problems, a priori solution estimates and error estimates that reduce to the Arnold-Falk-Winther results in the linear case. We also consider the impact of variational crimes, extending the results of our previous article to these semilinear problems. As an immediate application, this new framework allows for mixed finite element methods to be applied to semilinear problems on surfaces.

description: At low temperatures, colloidal particles with short-range attractive and long-range repulsive interactions can form various periodic microphases in bulk.In this paper, we investigate the self-assembly behaviour of colloids with competing interactions under spherical confinement by conducting molecular dynamics simulations. We find that the cluster, mixture, cylindrical, perforated lamellar and lamellar structures can be obtained, but the details of the ordered structures are different from those in bulk systems. Interestingly, the system tends to form more perforated structures when confined in smaller spheres. The mechanism behind this phenomenon is the relationship between the energy of the ordered structures and the bending of the confinement wall, which is different from the mechanism in copolymer systems.

Classification of Alzheimer's using deep-learning methods on webcam-based gaze data
Creators: name: Harisinghani, Anuj
Publisher: name: University of British Columbia
Year: 2023

description: There has been increasing interest in non-invasive predictors of Alzheimer’s disease (AD) as an initial screening for this condition. Previously, successful attempts leveraged eye-tracking and language data generated during picture narration and reading tasks. These results were obtained with high-end, expensive eye-trackers. We explore classification using eye-tracking data collected with a webcam, where our classifiers are built using a deep-learning approach. Our results show that the webcam gaze classifier is not as good as the classifier based on high-end eye-tracking data, meaning its AU-ROC, Sensitivity and Specificity are significantly lower. However, the webcam-based classifier still beats a majority-class baseline classifier in terms of AU-ROC, indicating that predictive signals can be extracted from webcam gaze tracking. Our results provide an encouraging proof of concept that webcam gaze tracking should be further explored as an affordable alternative to high-end eye-trackers for the detection of AD.
Spectroscopy of the soliton lattice formation in quasi-one-dimensional fermionic superfluids with population imbalance

description: Motivated by recent experiments in low-dimensional trapped fermionic superfluids, we study a quasi-one-dimensional (quasi-1D) superfluid with a population imbalance between two hyperfine states using an exact mean-field solution for the order parameter. When an effective "magnetic field" exceeds a critical value, the superfluid order parameter develops spatial inhomogeneity in the form of a soliton lattice. The soliton lattice generates a band of quasiparticle states inside the energy gap, which originate from the Andreev bound states localized at the solitons. Emergence of the soliton lattice is accompanied by formation of a spin-density wave, with the majority fermions residing at the points in space where the Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) order parameter vanishes. We discuss possibilities for experimental detection of the quasi-1D FFLO state using elastic and inelastic optical Bragg scattering and radio-frequency spectroscopy. We show that these measurements can provide necessary information for unambiguous identification of the spatially-inhomogeneous quasi-1D FFLO state and the soliton lattice formation.

Year: 2022

description: This paper examines and evaluates the challenges and opportunities of export credit agencies (ECA) in the Middle East and North Africa (MENA) region. Political risks, unrest and instability made exports in the MENA region arduous. Further challenges are demonetization, the lack of reliable information and the acquisition of skilled employees. Access to financial resources can be quite challenging and several ECAs in the MENA region struggle from having no economies of scale. The global trend of globalisation and digitalisation has proved to be both a challenge and an opportunity. Nevertheless, the ECAs are becoming progressively important and needed in the MENA region. ECAs can benefit from this by working closely with financial institutions, banks and stakeholders. Other opportunities are infrastructure, renewable energies, international events and the diversification of the product portfolio. Through research on the ECAs EGE, ECI, Credit Oman and ICIEC, differences of multilateral and national export credit agencies have been analysed as well.

description: We obtain an analytical equation of state for one-dimensional strongly attractive Fermi gas for all parameter regime in current experiments. From the equation of state we derive universal scaling functions that control whole thermodynamical properties in quantum critical regimes and illustrate physical origin of quantum criticality. It turns out that the critical properties of the system are described by these of free fermions and those of mixtures of fermions with mass $m$ and $2m$. We also show how these critical properties of bulk systems can be revealed from the density profile of trapped Fermi gas at finite temperatures and can be used to determine the T=0 phase boundaries without any arbitrariness.

A method has been developed based on the analysis of the time interval recorded by a valve motion sensor in the form of a monotonically decreasing function after the response of a mussel colony to the influence of a vibroacoustic signal. The method makes it possible to eliminate the calibration of the opening value of the mussel valves at the stage of manufacturing and setting up the biosensor system, as well as to control and determine false positives or incomplete opening of the valves of individual mussels when exposed to point stimuli.

description: The aim of the essay is to identify current trends in infrastructure financing in times of net zero, crucial challenges, and solutions to overcome these issues. To gain information, a fundamental literal research, and interviews with infrastructure financing specialists of development banks were conducted. The growing importance of climate aspects for financing decisions, the changing sources of infrastructure funding and the increased role of Multilateral Development Banks (MDBs) can be listed as the most important trends. The main challenges are the financing gap for infrastructure, the high investment risks and a lack of standards, and policies regarding climate neutrality. To overcome these challenges, innovative financing solutions and the merging of public and private funding have been identified as potential solutions.

The brightness of magnetic field concentrations in the quiet Sun

Year: 2010
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: In addition to the `facular' brightening of active regions, the quiet Sun also contains a small scale magnetic field with associated brightenings in continuum radiation. We measure this contribution of quiet regions to the Sun's brightness from high spatial resolution (0"16-0"32) observations of the Swedish 1-m Solar Telescope (SST) and Hinode satellite. The line-of-sight magnetic field and continuum intensity near \ion{Fe}{i} 6302.5 Å are used to quantify the correlation between field strength and brightness. The data show that magnetic flux density contains a significant amount of intrinsically weak fields that contribute little to brightness. We show that with data of high spatial resolution a calibration of magnetic flux density as a proxy for brightness excess is possible. In the SST data, the magnetic brightening of a quiet region with an average (unsigned) flux density of 10 G is about 0.15%. In the Hinode data, and in SST data reduced to Hinode resolution, the measured brightening is some 40% lower. With appropriate correction for resolution, magnetic flux density can be used as a reliable proxy in regions of small scale mixed polarity. The measured brightness effect is larger than the variation of irradiance over a solar cycle. It is not clear, however, if this quiet Sun contribution actually varies significantly. \keywords{Sun: surface magnetism -- photosphere -- solar-terrestrial relations}

description: Supersymmetric monojets may be produced at the Large Hadron Collider by the process qg -> squark neutralino_1 -> q neutralino_1 neutralino_1, leading to a jet recoiling against missing transverse momentum. We discuss the feasibility and utility of the supersymmetric monojet signal. In particular, we examine the possible precision with which one can ascertain the neutralino_1-squark-quark coupling via the rate for monojet events. Such a coupling contains information on the composition of the neutralino_1 and helps bound dark matter direct detection cross-sections and the dark matter relic density of the neutralino_1. It also provides a check of the supersymmetric relation between gauge couplings and gaugino-quark-squark couplings.

description: The use of motorized treadmills as convenient tools for the study of locomotion has been in vogue for many decades. However, despite the widespread presence of these devices in many scientific and clinical environments, a full consensus on their validity to faithfully substitute free overground locomotion is still missing. Specifically, little information is available on whether and how the neural control of movement is affected when humans walk and run on a treadmill as compared to overground. Here, we made use of linear and non-linear analysis tools to extract information from electromyographic recordings during walking and running overground, and on an instrumented treadmill. We extracted synergistic activation patterns from the muscles of the lower limb via non-negative matrix factorization. We then investigated how the motor modules (or time-invariant muscle weightings) were used in the two locomotion environments. Subsequently, we examined the timing of motor primitives (or time-dependent coefficients of muscle synergies) by calculating their duration, the time of main activation, and their Hurst exponent, a non-linear metric derived from fractal analysis. We found that motor modules were not influenced by the locomotion environment, while motor primitives were overall more regular in treadmill than in overground locomotion, with the main activity of the primitive for propulsion shifted earlier in time. Our results suggest that the spatial and sensory constraints imposed by the treadmill environment might have forced the central nervous system to adopt a different neural control strategy than that used for free overground locomotion, a data-driven indication that treadmills could induce perturbations to the neural control of locomotion.

description: Quantum physics modeling is technically complex and often non-descriptive. This article presents some approaches how quantum physical ideas can be represented by haptic models. For this purpose, models made from 3D printers, models made from paper strips, and models made from textiles are compared. A novelty is the use of zippers instead of paper strips, which can be easily ''cut'' and ''glued'' together. The models have been developed primarily with the aim of conveying and visualizing topological ideas with little basic mathematical knowledge.

description: We present one of the most precise measurement to date of the spatial clustering of X-ray selected AGNs using a sample derived from the Chandra X-ray Observatory survey in the Bootes field. The real-space two-point correlation function over a redshift interval from z=0.17 to z~3 is well described by the power law, xi(r)=(r/r0)^-gamma, for comoving separations r=0.37 and r0=6.9+-1.0 h^-1 Mpc for =1.28). Further, we are able to measure the projections of the two-point correlation function both on the sky plane and in the line of sight. We use these measurements to show that the Chandra/Bootes AGNs are predominantly located at the centers of dark matter halos with the circular velocity Vmax>320 km/s or M_200 > 4.1e12 h^-1 Msun, and tend to avoid satellite galaxies in halos of this or higher mass. The halo occupation properties inferred from the clustering properties of Chandra/Bootes AGNs --- the mass scale of the parent dark matter halos, the lack of significant redshift evolution of the clustering length, and the low satellite fraction --- are broadly consistent with the Hopkins et al. scenario of quasar activity triggered by mergers of similarly-sized galaxies.

description: Moral distress is a concept that is not yet clearly delineated and is the subject of much debate; it describes “the suffering that arises when one knows what is right to do, but institutional constraints make it almost impossible to follow the right course of action”. So moral distress occurs unconsciously when an individual acts against their ethical principles and values.

description: We study the problem of representation of statistical data (of any origin) by a complex probability amplitude. This paper is devoted to representation of data collected from measurements of two trichotomous observables. The complexity of the problem eventually increased comparing to with the case of dichotomous observables. We see that only special statistical data (satisfying s number of nonlinear constraints) have the quantum--like representation.

Modularizing deep learning for geometry-aware registration and reconstruction
Creators: name: Jiang, Wei
Publisher: name: University of British Columbia
Year: 2023

description: In this work, we explore the modularization of deep learning for geometry-aware registration and reconstruction, with a particular focus on cameras registration and human reconstruction from videos. The traditional methods for these tasks have been challenged by deep learning approaches, but end-to-end learning can be limited in terms of generalization, transparency, and controllability. Modularization breaks the task into smaller subtasks and allows each to be addressed individually using traditional methods or deep learning techniques. Through modularization, we are able to embed knowledge from the real world, enabling better generalization, simpler and more effective learning, explainable and transparent models, and geometry-awareness. Specifically, this work consists of four major chapters, each presenting a modularized approach to solve a specific geometric problem. Firstly, a novel linearized multi-sampling method is proposed to enable better image alignment and learning. Secondly, the homography warping is modularized out of the pipeline allowing optimization through the learned error for accurate sports field registration. Thirdly, by modularizing the robust estimation and 3D map from the pose estimation pipeline, the neural network can focus on learning accurate image correspondences. Finally, the modularization of human scene positioning and mesh skinning allows for the reconstruction of animatable human avatar from video. Overall, our work demonstrates the power of modularization, and we hope it will inspire future research on modularization and its potential applications to other areas.

Do logical intuitions rely on information processing or logical form

description: There is evidence that people are able to make rapid, intuitive judgments of the validity of some simple inferences. Initial studies have claimed that these judgments are based on the logical form of the inferences. However, more recent studies have claimed that people are using non-logical cues in order to make these inferences. In these two studies, we examine the hypothesis that these intuitive judgments reflect information processing parameters more than logical form, when extraneous cues are not available. Specifically, we compare judgements to Affirmation of the consequent inferences which lead to the same believable conclusion. The only difference between the two forms concerns the number of alternative antecedents available for the major premise. For example "All flowers grow. Tulips grow. Therefore Tulips are flowers." compared to "All flowers have petals. Tulips have petals. Therefore Tulips are flowers." For both inferences, the form, the basic parameters and the conclusion are identical. However, the major premise for the former allows many possible alternatives (i.e. other things that grow), while the major premise for the latter has very few such alternatives (other things that have petals). Our basic hypothesis is that reasoners will process the difference between these two types of inference, using two measures of intuitive reasoning. In Study 1, we will present participants with both types of premise and ask for a validity judgment and the degree of confidence for each. Our hypothsis here is that when conclusions are judged to be valid, mean confidence will be higher for premises with few alternatives. In Study 2, we will use the liking method. Participants will be presented with few and many forms of these inferences and asked the extent to which they like the conclusion. Our hypothesis here is that conclusions associated with premises having few alternatives will show higher liking ratings than those with many alternatives.

Quasiparticle scattering from vortices in d-wave superconductors. II. Berry phase contribution

description: In the mixed state of a d-wave superconductor, Bogoliubov quasiparticles are scattered from magnetic vortices via a combination of two effects: Aharonov-Bohm scattering due to the Berry phase acquired by a quasiparticle upon circling a vortex, and effective potential scattering due to the superflow swirling about the vortices. In this paper, we consider the Berry phase contribution in the absence of superflow, which results in branch cuts between neighboring vortices across which the quasiparticle wave function changes sign. Here, the simplest problem that captures the physics is that of scattering from a single finite branch cut that stretches between two vortices. Elliptical coordinates are natural for this two-center problem, and we proceed by separating the massless Dirac equation in elliptical coordinates. The separated equations take the form of the Whittaker-Hill equations, which we solve to obtain radial and angular eigenfunctions. With these eigenfunctions in hand, we construct the scattering cross section via partial wave analysis. We discuss the scattering effect of Berry phase in the absence of superflow, having considered the superflow effect in the absence of Berry phase in a separate paper. We also provide qualitative comparison of transport cross sections for the Berry phase and the Superflow effects. The important issue of interference between the two effects is left to future work.

description: We show that the category of finite-dimensional modules over the endomorphism algebra of a rigid object in a Hom-finite triangulated category is equivalent to the Gabriel-Zisman localisation of the category with respect to a certain class of maps. This generalises the 2-Calabi-Yau tilting theorem of Keller-Reiten, in which the module category is obtained as a factor category, to the rigid case.

description: The Metaverse is gaining attention among academics as maturing technologies empower the promises and envisagements of a multi-purpose, integrated virtual environment. An interactive and immersive socialization experience between people is one of the promises of the Metaverse. In spite of the rapid advancements in current technologies, the computation required for a smooth, seamless and immersive socialization experience in the Metaverse is overbearing, and the accumulated user experience is essential to be considered. The computation burden calls for computation offloading, where the integration of virtual and physical world scenes is offloaded to an edge server. This paper introduces a novel Quality-of-Service (QoS) model for the accumulated experience in multi-user socialization on a multichannel wireless network. This QoS model utilizes deep reinforcement learning approaches to find the near-optimal channel resource allocation. Comprehensive experiments demonstrate that the adoption of the QoS model enhances the overall socialization experience.

Next, dead cells were excluded by Live/Dead staining, and nucleated cells were gated with CD45. After using CD3 and CD14, a subset of CD3-positive CD14-negative CD56-positive cells was defined as NKT cells and a subset of CD3-negative CD14-negative CD56-positive cells as NK cells for downstream analysis. For each subset, We analyzed CD16-positive, CD35-positive, CD88-positive, CD69-positive, and CD83-positive rates; for NKT cells, we also analyzed TCR Vα24-positive rates.

description: This study aims to investigate the lives of adult methamphetamine users in Germany. This qualitative research focuses on how people become addicted to methamphetamine, what are the key harmful effects of the substance on various fields of life. The available literature on this topic analysed nine studies on methamphetamine use.Extensive study has been performed to clarify the impact of methamphetamine. A US research on the neurophysiological and compartmental effects of misuse of crystal methamphetamine found these abuses causedamage to brain regions associated with social cognition and could thus contribute to social cognitive disability.Although methamphetamine is a desire for socialization, the findings indicate that chronic use is associated withdepression, violence, and social isolation.
