description: In this paper we study minimal affinizations of representations of quantum groups (generalizations of Kirillov-Reshetikhin modules of quantum affine algebras introduced by Chari). We prove that all minimal affinizations in types A, B, G are special in the sense of monomials. Although this property is not satisfied in general, we also prove an analog property for a large class of minimal affinization in types C, D, F. As an application, the Frenkel-Mukhin algorithm works for these modules. For minimal affinizations of type A, B we prove the thin property (the l-weight spaces are of dimension 1) and a conjecture of Nakai-Nakanishi (already known for type A). The proof of the special property is extended uniformly for more general quantum affinizations of quantum Kac-Moody algebras.

description: A new calculation of the atmospheric fluxes of cosmic-ray hadrons and muons in the energy range 10-10^5 GeV has been performed for the set of hadron production models, EPOS 1.6, QGSJET II-03, SIBYLL 2.1, and others that are of interest to cosmic ray physicists. The fluxes of secondary cosmic rays at several levels in the atmosphere are computed using directly data of the ATIC-2, GAMMA experiments, and the model proposed recently by Zatsepin and Sokolskaya as well as the parameterization of the primary cosmic ray spectrum by Gaisser and Honda. The calculated energy spectra of the hadrons and muon flux as a function of zenith angle are compared with measurements as well as other calculations. The effect of uncertainties both in the primary cosmic ray flux and hadronic model predictions on the spectra of atmospheric hadrons and muons is considered.

description: The object of study of this thesis is the support techniques, at a pre-writing stage, of adolescents with Dysgraphia, during the secondary education. Τhrough this bibliographic approach, the thesis attempts to examine and compare traditional practices to contemporary ones, which make extensive use of New Technologies. Concurrently, the study demonstrates concerns arising from the incorporation of Information and Communication Technologies in treatment interventions designed to improve the writing skills of adolescents with a Written Expression Disorder. According to the pertinent literature, techniques which combine teaching support and feedback during learning activities, as well as a selection of the appropriate language-teaching tools, prove more effective for secondary students with Dysgraphia. Additionally, it is concluded that exclusive use of technological means does not ensure success of the treatment programme and, therefore, it is suggested that technology should be applied discerningly on the basis of specific objectives and target outputs, in order to achieve optimal support of students’ individual needs
Rational self-directed hypnotherapy : a therapeutic intervention for major depression
Creators: name: McBride, Maureen L.
Publisher: name: University of British Columbia
Year: 2009

description: The efficacy of a rational hypnotherapeutic intervention for unipolar major depression is the focus of this study. Based on a single subject research design, the participant was asked to complete pre-therapy, during and post-therapy assessments of depression, anger and dysfunctional attitudes. Pre-therapy testing, to collect a baseline measure, was conducted two weeks prior to therapy, and therapy lasted 12 weeks. Post-therapy measures were taken one week after therapy, and a follow-up assessment was done six months post therapy. The intervention was comprised of progressive relaxation, guided imagery, and cognitive restructuring and behavioral rehearsal based on the A-B-C-D-E paradigm. The participant examined his self-defeating or irrational thoughts in critical incidents and his subjective emotional and behavioral reactions. He was then asked to substitute his own more rational thoughts in the same situation. Post-therapy results from the assessment devices and self-reports demonstrated significant improvement in all areas. Following the rational hypnotherapeutic intervention, the participant showed decreased symptoms of depression, decreased dysfunctional attitudes and decreased anger and irritation. He also reported subjective feelings of emotional well-being. This improvement was maintained in the six-month follow-up. Rational Self-Directed Hypnotherapy is shown to be an effective, relatively short term intervention that encourages the client to play an active role in finding new ways to successfully deal with problems, and accept control over his/her own life.

description: Environmental pollutants are a source for reliability issues across data center and telecommunications equipment. A primary driver of this is the transport and deposition of particle matter (PM$_{2.5}$, PM$_{10}$) on printed circuit boards, electronic components and heat exchange surfaces. This process is enhanced by turbulent air flows generated from cooling fans. Particle pollutants can persist after contemporary filtering, highlighting the importance of elucidating particle transport mechanisms and utilising this information to design robust equipment. This study investigates particle transport behaviour arising from axial fans operating under varied aerodynamic conditions. Transient, multi-phase numerical simulations were performed to model the flow of millions of microscale particles in air and determine their fate. Across a comprehensive range of fan operation conditions, from aerodynamic stall to free delivery, non-dimensional deposition velocities spanned an order of magnitude. Deposition profiles vary from monotonic to non-monotonic behaviour, influenced by local flow impingement, blade tip vortices, and shear velocity. A simple flow control solution that mitigates the factors influencing deposition has been demonstrated for equipment already deployed. The findings and numerical methods can be applied for the optimization of fan-cooled equipment intended for indoor and outdoor environments where air quality is poor, or pollution levels are high.

description: The combined data of the University of Michigan Radio Astronomy Observatory and Metsahovi Radio Observatory provide us with radio light curves for Active Galactic Nuclei monitored by both observatories from 4.8 to 37 GHz covering time intervals up to ~25 years. We consider here such composite light curves for four gamma-ray blazars that have been nearly continuously monitored at both observatories: 0458-020, 0528+134, 1730-130 and 2230+114. We have decomposed the most prominent outbursts in the light curves of these four blazars into individual components using Gaussian model fitting, and estimated the epochs, amplitudes, and half-widths of these components as functions of frequency. We attempt to distinguish "core outbursts", which show frequency-dependent time delays and are associated with brightening of the core, from "jet outbursts", which appear nearly synchronously at all frequencies and are accompanied by the emergence of new jet components and their subsequent evolution. Available 43 GHz VLBA images allow us to identify only one pure core outburst (in 2230+114) and one pure jet outburst (0458-020). Most of the outbursts analyzed are mixed, in the sense that they display frequency-dependent time delays (i.e., they are optically thick) and are associated with the eventual emergence of new jet components. The maxima of the jet and mixed outbursts probably correspond to epochs when newly ejected components become fully optically thin. These epochs are also marked by a significant increase in the angular velocities of the ejected components. There is evidence that the outbursts in 2230+114 repeat every 8.0+-0.3 years, with the positions of individual sub-outbursts being preserved from one quasi-periodic eight-year cycle to another, even though their amplitudes vary by more than a factor of two.

We then review the multivariate extension due to Carlier et al. (2016, 2017) which relates vector quantile regression to an optimal transport problem with mean independence constraints. We introduce an entropic regularization of this problem, implement a gradient descent numerical method and illustrate its feasibility on univariate and bivariate examples.

A holographic model of deconfinement and chiral symmetry restoration

description: We analyze the finite temperature behavior of the Sakai-Sugimoto model, which is a holographic dual of a theory which spontaneously breaks a U(N_f)_L x U(N_f)_R chiral flavor symmetry at zero temperature. The theory involved is a 4+1 dimensional supersymmetric SU(N_c) gauge theory compactified on a circle of radius R with anti-periodic boundary conditions for fermions, coupled to N_f left-handed quarks and N_f right-handed quarks which are localized at different points on the compact circle (separated by a distance L). In the supergravity limit which we analyze (corresponding in particular to the large N_c limit of the gauge theory), the theory undergoes a deconfinement phase transition at a temperature T_d = 1 / 2 πR. For quark separations obeying L > L_c = 0.97 * R the chiral symmetry is restored at this temperature, but for L < L_c = 0.97 * R there is an intermediate phase which is deconfined with broken chiral symmetry, and the chiral symmetry is restored at T = 0.154 / L. All of these phase transitions are of first order.

Adaptation to divorce: mapping women’s experience using grounded theory
Creators: name: Zaide, PohSuan
Publisher: name: University of British Columbia
Year: 2009

description: A grounded theory design was used in this investigation of women's experiences of adapting to separation and divorce. The focus of the study was on explicating the social processes that shape the ways in which women negotiate the changes brought on by the termination of their marriages. In-depth interviews were conducted with eight women from the Greater Vancouver area. The women described (a) the circumstances that led up to their physical separation from their husbands, (b) what changes they felt resulted, (c) what they had to do to manage those changes, (d) what facilitated or hindered their coping efforts, and (e) what they would like for themselves in their new lives. Results of the study highlighted the complexity and variety of women's experiences, and supported the notion that adaptation for these women was a dynamic process that reflected the interaction of various 'dimensions' of their experience. These 'dimensions' were linked in a conceptual model that reflected the basic social process of transforming. The model also situated the perceived impact of separation and divorce, and women's subsequent coping efforts in the rich contexts of their lives.

description: A number of theoretical and lattice results lead us to believe that Quark-Gluon Plasma not too far from $T_c$ contains not only electrically charged quasiparticles -- quarks and gluons -- but magnetically charged ones -- monopoles and dyons -- as well. Although binary systems like charge-monopole and charge-dyon were considered in details before in both classical and quantum settings, it is the first study of coexisting electric and magnetic particles in many-body context. We perform Molecular Dynamics study of strongly coupled plasmas with $\sim 1000$ particles and different fraction of magnetic charges. Correlation functions and Kubo formulae lead to such transport properties as diffusion constant, shear viscosity and electric conductivity: we compare the first two with empirical data from RHIC experiments as well as results from AdS/CFT correspondence. We also study a number of collective excitations in these systems.
description: 2nd version, 22 pages, 32 figures: two important new figures have been included to compare our results with RHIC experiments and AdS/CFT results; a few new references and comments are added as well

description: We review properties of so-called special conformal Killing tensors on a Riemannian manifold $(Q,g)$ and the way they give rise to a Poisson-Nijenhuis structure on the tangent bundle $TQ$. We then address the question of generalizing this concept to a Finsler space, where the metric tensor field comes from a regular Lagrangian function $E$, homogeneous of degree two in the fibre coordinates on $TQ$. It is shown that when a symmetric type (1,1) tensor field $K$ along the tangent bundle projection $τ: TQ\to Q$ satisfies a differential condition which is similar to the defining relation of special conformal Killing tensors, there exists a direct recursive scheme again for first integrals of the geodesic spray. Involutivity of such integrals, unfortunately, remains an open problem.

description: In recent years the physics of two-dimensional semiconductors was revived by the discovery of the class of transition metal dichalcogenides. In these systems excitons dominate the optical response in the visible range and open many perspectives for nonlinear spectroscopy. To describe the coherence and polarization dynamics of excitons after ultrafast excitation in these systems, we employ the Bloch equation model of a two-level system extended by a local field describing the exciton-exciton interaction. We calculate four-wave mixing signals and analyze the dependence of the temporal and spectral signals as a function of the delay between the exciting pulses. Exact analytical results obtained for the case of ultrafast ($δ$-shaped) pulses are compared to numerical solutions obtained for finite pulse durations. If two pulses are used to generate the nonlinear signal, characteristic spectral line splittings are restricted to short delays. When considering a three-pulse excitation the line splittings, induced by the local field effect, persist for long delays. All of the found features are instructively explained within the Bloch vector picture and we show how the exciton occupation dynamics govern the different four-wave mixing signals.
Biodegradation of plastics using microorganisms

Subjects: Biodegradation

description: Plastic is a broad name given to different polymers with high molecular weight, that produced by human and synthesized from oil. With the advances in technology and the increase in the global population, plastic materials have found wide applications in every aspect of life although most conventional plastics are non-biodegradable and their increasing accumulation in the environment has been a threat to plants, animals and human. Bioplastic production and development of conventional plastics degradation methods are the ways that can solve this problem. Bioplastics are biodegradable plastics, made from oil or biomass and degraded by microorganisms. Polymers such as PHA have been considered for medical applications since no harmful by-product are generated during PHA degradation. Furthermore, proteinase K can degrade both L-PLA and prion protein, so the mechanisms of plastics biodegradation can be used in studies about disease related to proteins structure. Polymers used in plastics producing, factors affecting the biodegradability, assessment of microbial and enzymatic degradation of plastics and their blends, and identified microorganisms are explained in this review.

description: A critical subject in fully differential QED calculations originates from numerical instabilities due to small fermion masses that act as regulators of collinear singularities. At next-to-next-to-leading order (NNLO) a major challenge is therefore to find a stable implementation of numerically delicate real-virtual matrix elements. In the case of Bhabha scattering this has so far prevented the development of a fixed-order Monte Carlo at NNLO accuracy. In this paper we present a new method for stabilising the real-virtual matrix element. It is based on the expansion for soft photon energies including the non-universal subleading term calculated with the method of regions. We have applied this method to Bhabha scattering to obtain a stable and efficient implementation within the McMule framework. We therefore present for the first time fully differential results for the photonic NNLO corrections to Bhabha scattering.

description: We study the properties of a dilute Bose condensed gas at zero temperature in the presence of a strong random potential with arbitrary correlation length. Starting from the underlying Gross-Pitaevskii equation, we use the random phase approximation in order to get a closed integral equation for the averaged density distribution which allows to determine both the condensate and the superfluid density. The obtained results generalize those of Huang and Meng (HM) to strong disorder. In particular, we find the critical value of the disorder strength, where the superfluid phase disappears by a first-order phase transition. We show how this critical value changes as a function of the correlation length.

description: The radical demographic changes that the educational institutions in multicultural societies may face, followed by massive population movements in recent decades has led to the need of reformulation of the educational policies. The educational systems of the countries which host migrants need to adapt their attitudes and give their educational structures an intercultural character that prepares students to be future citizens of a multicultural society who will accept and respect diversity and will contribute to the consolidation of the social peace. After a thorough study of policies, general regulations and measures implemented from time to time on the intercultural dimension of education, a teaching course on interculturalism is proposed within the framework of the 5th and 6th grade of Elementary School concerning the subject of Flexible Zone. The course is hosted on the Moodle LangTech Electronic Learning Platform of the Department of French Language and Literature at http://www.courses.langtech.gr/course/view.php?id=113. It was designed in order to be online, since the galloping advent of technology has affected the educational and the language learning process and has raised more opportunities for both students and tutors; offering a more attractive and effective learning environment

description: We present new two-sided constraints on Lorentz Invariance violation energy scale for photons with quartic dispersion relation from recent gamma ray observations by Tibet-AS$γ$ and LHAASO experiments. The constraints are based on the consideration of the processes of photon triple splitting (superluminal scenario) and the suppression of shower formation (subluminal). The constraints in subluminal scenario are better than the pair production constraints and are the strongest in the literature.

description: Quite recently, some new mathematical approaches to black holes have appeared in the literature. They do not rely on the classical concept of event horizon -- which is very global, but on the local concept of hypersurfaces foliated by trapped surfaces. After a brief introduction to these new horizons, we focus on a viscous fluid analogy that can be developed to describe their dynamics, in a fashion similar to the membrane paradigm introduced for event horizons in the seventies, but with a significant change of sign of the bulk viscosity.

description: Σκοπός ήταν να ελεγχθεί η συμβολή ενός προγράμματος που βασίζεται στις αρχές της ψυχοκινητικής στην εξοικείωση των μαθητών με την έννοια της αναπηρίας και στην πιθανή μεταβολή των αντιλήψεών τους απέναντι στα άτομα με αναπηρία. Το πρόγραμμα σχεδιάστηκε με βάση τις θεωρίες συμπεριφοράς που οδηγούν στη μεταβολή των στάσεων του ατόμου και περιελάμβανε αφήγηση ιστοριών και δραστηριότητες ψυχοκινητικής. Η διάρκεια του προγράμματος ήταν 12 εβδομάδες. Το δείγμα (Ν=46) χωρίστηκε σε δύο ομάδες, ελέγχου (Ν=22) και παρέμβασης (Ν=24). Η ομάδα ελέγχου παρακολούθησε τις ίδιες θεματικές χωρίς όμως τις δραστηριότητες της ψυχοκινητικής. Αξιολογήθηκαν η κατανόηση και οι αντιλήψεις των παιδιών απέναντι στην αναπηρία με τρία ψυχομετρικά εργαλεία πριν και μετά την παρέμβαση. Από τα αποτελέσματα φάνηκε ότι υπήρξε στατιστικά σημαντική επίδραση σε όλες τις μεταβλητές που αξιολογήθηκαν μόνο για την ομάδα παρέμβασης. Συμπερασματικά, ένα βιωματικό εκπαιδευτικό πρόγραμμα όπου συνδυάζει την αφήγηση ιστοριών με ψυχοκινητικές δραστηριότητες και προσφέρει ποικιλία ερεθισμάτων, μπορεί να συμβάλλει ουσιαστικά στην κατανόηση και την αποδοχή της αναπηρίας από τα μικρά παιδιά
description: The purpose was to examine the contribution of a program based on the principles of psychomotor training to familiarize students with the concept of disability and possibly change their perceptions towards people with disabilities. The program was designed based on behavioral theories that lead to change of individual’s attitudes and included reading stories and psychomotor activities. The program lasted 12 weeks. The sample (N = 46) was divided into two groups, control group (N=22) and intervention group (N=24). The control group followed the same program without the activities of psychomotor. Children's understanding and perceptions of disability were assessed with three psychometric tools before and after the intervention. The results showed that there was a statistically significant effect on all of the variables assessed only for the intervention group. In conclusion, an experiential educational program combining narrative stories with psychomotor activities and a variety of stimuli can make a significant contribution to the understanding and acceptance of disability by young children

description: A dense Bose gas with hard-core interaction is considered in an optical lattice. We study the phase diagram in terms of a special mean-field theory that describes a Bose-Einstein condensate and a Mott insulator with a single particle per lattice site for zero as well as for non-zero temperatures. We calculate the densities, the excitation spectrum and the static structure factor for each of these phases.

description: First observed in 1995, the top quark is one of a pair of third-generation quarks in the Standard Model of particle physics. It has charge +2/3e and a mass of 171.4 GeV, about 40 times heavier than its partner, the bottom quark. The CDF and D0 collaborations have identified several hundred events containing the decays of top-antitop pairs in the large dataset collected at the Tevatron proton-antiproton collider over the last four years. They have used these events to measure the top quark's mass to nearly 1% precision and to study other top quark properties. The mass of the top quark is a fundamental parameter of the Standard Model, and knowledge of its value with small uncertainty allows us to predict properties of the as-yet-unobserved Higgs boson. This paper presents the status of the measurements of the top quark mass.

description: We study the attractor mechanism of dual pairs of black brane bounds in N=2 supergravity in six and seven dimensions. First, we consider the effective potentials of the 6D and 7D black branes as well as their entropies. The contribution coming from the SO(1,1) factor of the moduli spaces M_{6D} and M_{7D} of these theories is carefully analyzed and it is used to motivate the study of the dual black branes bounds; which in turn allow to fix the critical value of the dilaton at horizon. The attractor eqs of the black branes and the bound pairs are derived by combining the criticality conditions of the corresponding effective potentials and the Lagrange multiplier method capturing constraints eqs on the fields moduli.

description: We used x-ray photoemission spectroscopy to investigate the electronic structure of the Mott insulator LaVO3 embedded in LaAlO3. By limiting the upper layer of LaAlO3 to 3 unit cells, the underlying LaVO3 could be probed. The V 2p core-level spectra had both V3+ and V4+ components, and above 2 unit cell thick LaVO3, the structures exhibited spectra similar to bulk samples. The atomically flat surfaces enabled study of the emission angle dependence, which indicates the V4+ is localized to the topmost layer. These results demonstrate the potential for probing interface electronic structure in oxide ultrathin films by surface spectroscopy.

description: Course estimation is a key component for the development of autonomous navigation systems for robots. While state-of-the-art methods widely use visual-based algorithms, it is worth noting that they all fail to deal with the complexity of the real world by being computationally greedy and sometimes too slow. They often require obstacles to be highly textured to improve the overall performance, particularly when the obstacle is located within the focus of expansion (FOE) where the optic flow (OF) is almost null. This study proposes the FAst ITerative Half-plane (FAITH) method to determine the course of a micro air vehicle (MAV). This is achieved by means of an event-based camera, along with a fast RANSAC-based algorithm that uses event-based OF to determine the FOE. The performance is validated by means of a benchmark on a simulated environment and then tested on a dataset collected for indoor obstacle avoidance. Our results show that the computational efficiency of our solution outperforms state-of-the-art methods while keeping a high level of accuracy. This has been further demonstrated onboard an MAV equipped with an event-based camera, showing that our event-based FOE estimation can be achieved online onboard tiny drones, thus opening the path towards fully neuromorphic solutions for autonomous obstacle avoidance and navigation onboard MAVs.

Rosebush Q-Sort: the use of drawings in the assessment of child abuse
Creators: name: Robertson, Sarah
Publisher: name: University of British Columbia
Year: 2009

description: The use of the Rosebush Visualization Technique (RVT) (Allan & Crandell, 1986) as a tool in the early detection of child abuse is tested using the Q-Sort Methodology. Twenty children between the ages of 8 and 13 inclusively are selected based on their membership in either an abused group or non-abused group. The mean age of the children in the abused group was 10.1 years and the mean age of the children in the non-abused group was 11.0 years. The abused group included 9 boys and 1 girl all of whom had been assessed by a mental health agency as having confirmed histories of abuse. The non-abused group consisted of 5 boys and 5 girls. Each child was seen individually and instructed to take a minute or so to imagine themselves as a rosebush. Each child was then asked to look at 24 pictures of rosebushes previously drawn by both abused and non-abused children and asked to choose the drawing which most resembled his/her imagined rosebush and the drawing which least resembled his/her imagined rosebush. The selection of the drawings continued until all 24 drawings were ordered into a Q-Sort. The Sort was analyzed using the Q-Sort methodology and Analysis of Variance techniques. The results supported the hypothesis that the children will show no preference for the drawings which represent the group to which they belong and that the drawings will not be differentially selected by both groups of children. The results are discussed followed by implications for clinical practice and recommendations for further research.

description: Composite fermion metal states emerge in quantum Hall bilayers at total Landau level filling factor $ν_T$=1 when the tunneling gap collapses by application of in-plane components of the external magnetic field. Evidence of this transformation is found in the continua of spin excitations observed by inelastic light scattering below the spin-wave mode at the Zeeman energy. The low-lying spin modes are interpreted as quasiparticle excitations with simultaneous changes in spin orientation and composite fermion Landau level index.
