Exploring psychosocial and therapeutic needs among refugees and asylum-seekers
Creators: name: Winterson, Marie
Publisher: name: Lancaster University
Year: 2019

description: Part one of this thesis explored the impact of gender on the
      post-migration experiences of refugees and asylum-seekers. A narrative
      review was conducted, which examined the findings of existing research in
      relation to theory and policy. The review identified key areas in which
      gender appears to interact with other variables that affect psychosocial
      wellbeing following migration: Integration, employment and social status;
      The changing nature of gender roles within the home; and Gender roles,
      culture and domestic violence. The findings demonstrate that gender is an
      important factor in how refugee and asylum-seeking men and women navigate
      changes post-migration.

      Part two focuses on the therapeutic needs of refugees and asylum-seekers
      who have experienced torture. Specialist therapists were interviewed about
      their experience of working holistically with this client group. Four
      themes were developed from the analysis: Therapy versus therapeutic:
      Addressing complex needs; The role of the therapist: Reparenting and
      bearing witness; “Trauma” and the meaning of recovery; and When it is safe
      and necessary to end? The implications of the findings for clinical
      psychologists in statutory services are discussed.

      Part three is a critical appraisal of the research process itself,
      focusing in particular upon the iterative nature of qualitative research
      and considerations regarding conducting research in collaboration with a
      third-sector organisation.

description: We determine the magnetic helicity, along with the magnetic energy, at high latitudes using data from the Ulysses mission. The data set spans the time period from 1993 to 1996. The basic assumption of the analysis is that the solar wind is homogeneous. Because the solar wind speed is high, we follow the approach first pioneered by Matthaeus et al. (1982, Phys. Rev. Lett. 48, 1256) by which, under the assumption of spatial homogeneity, one can use Fourier transforms of the magnetic field time series to construct one-dimensional spectra of the magnetic energy and magnetic helicity under the assumption that the Taylor frozen-in-flow hypothesis is valid. That is a well-satisfied assumption for the data used in this study. The magnetic helicity derives from the skew-symmetric terms of the three-dimensional magnetic correlation tensor, while the symmetric terms of the tensor are used to determine the magnetic energy spectrum. Our results show a sign change of magnetic helicity at wavenumber k~2 AU^{-1} (or frequency nu~2 uHz) at distances below 2.8 AU and at k~30 AU^{-1} (or nu~25 uHz) at larger distances. At small scales the magnetic helicity is positive at northern heliographic latitudes and negative at southern latitudes. The positive magnetic helicity at small scales is argued to be the result of turbulent diffusion reversing the sign relative to what is seen at small scales at the solar surface. Furthermore, the magnetic helicity declines toward solar minimum in 1996. The magnetic helicity flux integrated separately over one hemisphere amounts to about 10^{45} Mx^2/cycle at large scales and to a 3 times lower value at smaller scales.

description: A measurement of the top-quark pair-production cross section in ppbar collisions at sqrt{s}=1.96 TeV using data corresponding to an integrated luminosity of 1.12/fb collected with the Collider Detector at Fermilab is presented. Decays of top-quark pairs into the final states e nu + jets and mu nu + jets are selected, and the cross section and the b-jet identification efficiency are determined using a new measurement technique which requires that the measured cross sections with exactly one and multiple identified b-quarks from the top-quark decays agree. Assuming a top-quark mass of 175 GeV/c^2, a cross section of 8.5+/-0.6(stat.)+/-0.7(syst.) pb is measured.

Development of a UV-induced metal-oxide chemiresistive biosensor for lactate monitoring
Creators: name: Taleghani, Nastaran
Publisher: name: University of British Columbia
Year: 2022

description: Determining the concentration of biomarkers offers insights into the health condition and performance of the body. The vast majority of biosensors applied to measuring biomarkers in biological fluids are electrochemical bases; however, these biosensors suffer from several key drawbacks, thus preventing their widespread applications. These include the need to utilize complex sensing materials to obtain desirable analytical performance, which prevents their practical application, and to operate at a relatively high potential, which leads to inaccurate measurements due to the undesired oxidation of non-target molecules. A novel photo-induced chemiresistive biosensor is introduced here that addresses these challenges. A UV-induced ZnO nanorod chemiresistive biosensor was developed and applied to lactate monitoring in sweat as a model biomarker. The detection mechanism of lactate based on its interaction with ZnO nanorods was proposed. Furthermore, the effect of electrode design and operating parameters, including irradiance, radiation wavelength, and applied potential, were evaluated. The highest response, the shortest response time, and complete recovery were obtained at 5.6 mW/cm² irradiance of 365 nm and 0.1 V applied potential. The results indicated that the developed transduction platform utilizing a simple sensing layer is a promising technique with excellent analytical performance for detecting biomarkers. The selectivity challenge of the UV-induced ZnO nanorod chemiresistive biosensor was addressed by immobilizing lactate oxidase on the ZnO nanorods. The sensor exhibited excellent lactate monitoring capability within the dynamic range expected in the sweat. The appropriate amount of enzyme load of 10 units was found to provide the desired analytical performance. Further, the biosensor showed superb selectivity with responses of 1% or less of the lactate signal when exposed to interfering molecules, indicating its potential for analyzing the target iv biomarker in biological samples. Furthermore, the biosensor exhibited high reproducibility with a relative standard deviation of less than 2% and long-term storage stability (91% after five weeks), highlighting its potential for practical purposes. The overall results indicated the potential of this transduction platform as a promising technique with excellent analytical performance for detecting biomarkers, thereby paving the path toward the emergence of photo-induced chemiresistive biosensors for real-life applications.

description: We report on the crystal structure and magnetic behavior of the spin-1/2 compound AgVOAsO4. Magnetic susceptibility, high-field magnetization, and electron spin resonance measurements identify AgVOAsO4 as a gapped quantum magnet with a spin gap Delta ~ 13 K and a saturation field H_s ~ 48.5 T. Extensive band structure calculations establish the microscopic magnetic model of spin chains with alternating exchange couplings J ~ 40 K and J' ~ 26 K. However, the precise evaluation of the spin gap emphasizes the role of interchain couplings which are frustrated due to the peculiar crystal structure of the compound. The unusual spin model and the low energy scale of the exchange couplings make AgVOAsO4 a promising candidate for an experimental investigation of Bose-Einstein condensation and other exotic ground states in high magnetic fields.

description: We propose the first video diffusion framework for reference-based lineart video colorization. Unlike previous works that rely solely on image generative models to colorize lineart frame by frame, our approach leverages a large-scale pretrained video diffusion model to generate colorized animation videos. This approach leads to more temporally consistent results and is better equipped to handle large motions. Firstly, we introduce Sketch-guided ControlNet which provides additional control to finetune an image-to-video diffusion model for controllable video synthesis, enabling the generation of animation videos conditioned on lineart. We then propose Reference Attention to facilitate the transfer of colors from the reference frame to other frames containing fast and expansive motions. Finally, we present a novel scheme for sequential sampling, incorporating the Overlapped Blending Module and Prev-Reference Attention, to extend the video diffusion model beyond its original fixed-length limitation for long video colorization. Both qualitative and quantitative results demonstrate that our method significantly outperforms state-of-the-art techniques in terms of frame and video quality, as well as temporal consistency. Moreover, our method is capable of generating high-quality, long temporal-consistent animation videos with large motions, which is not achievable in previous works. Our code and model are available at https://luckyhzt.github.io/lvcd.

description: Clustering in high-dimensional spaces is nowadays a recurrent problem in many scientific domains but remains a difficult task from both the clustering accuracy and the result understanding points of view. This paper presents a discriminative latent mixture (DLM) model which fits the data in a latent orthonormal discriminative subspace with an intrinsic dimension lower than the dimension of the original space. By constraining model parameters within and between groups, a family of 12 parsimonious DLM models is exhibited which allows to fit onto various situations. An estimation algorithm, called the Fisher-EM algorithm, is also proposed for estimating both the mixture parameters and the discriminative subspace. Experiments on simulated and real datasets show that the proposed approach performs better than existing clustering methods while providing a useful representation of the clustered data. The method is as well applied to the clustering of mass spectrometry data.

description: Structural evolution in neutron-rich Os and W isotopes is investigated in terms of the Interacting Boson Model (IBM) Hamiltonian determined by (constrained) Hartree-Fock-Bogoliubov (HFB) calculations with the Gogny-D1S Energy Density Functional (EDF). The interaction strengths of the IBM Hamiltonian are produced by mapping the potential energy surface (PES) of the Gogny-EDF with quadrupole degrees of freedom onto the corresponding PES of the IBM system. We examine the prolate-to-oblate shape/phase transition which is predicted to take place in this region as a function of neutron number $N$ within the considered Os and W isotopic chains. The onset of this transition is found to be more rapid compared to the neighboring Pt isotopes. The calculations also allow prediction of spectroscopic variables (excited state energies and reduced transition probabilities) which are presented for the neutron-rich $^{192,194,196}$W nuclei, for which there is only very limited experimental data available to date.

Titolo lavoro ARM come nuova piattaforma didattica

Publisher: name: Scuola Universitaria della Svizzera Italiana (SUPSI)

description: Attualmente gli studenti SUPSI vengono formati alla tecnologia dei microcontrollori utilizzando una piattaforma di riferimento sviluppata una decina di anni fa in SUPSI. Questa piattaforma risulta poco attuale per rapporto a quanto diffuso nel contesto industriale. L'obiettivo di questo progetto è quindi quello di identificare/sviluppare una nuova piattaforma didattica per microcontrollori con architettura ARM. La nuova piattaforma dev'essere munita di tutte le maggiori tecnologie offerte dall'elettronica moderna. Tra queste sono degli esempi il display touch screen e le tecnologie di connessione senza fili. Per ottenere una piattaforma ricca di funzionalità è stato indispensabile uno studio di fattibilità approfondito, specie per determinare la tipologia di soluzione adatta. Un solo microcontrollore si è rivelato insufficiente a coprire le necessità della nuova piattaforma. La soluzione realizzata presenta un sistema modulare basato su due schede elettroniche. Queste possono venir utilizzate singolarmente in funzione delle esigenze di corso, oppure possono essere unite per creare una piattaforma didattica unica con due microcontrollori comunicanti tra loro.

The diffusion equation for the coherence of metastable states coupled with an excited state by laser radiation of different frequencies in a three-level scheme of the atom-field interaction is obtained in the strong-collision approximation. The dependence of the shape of an absorption line near the transmission maximum of one of the frequencies on the two-photon resonance detuning for various geometries of the cell is investigated.

Investigating the prevalence of taurodontism in an adolescent population using dental panoramic radiographs
Creators: name: Samji, Zahra Bahadurali
Publisher: name: University of British Columbia
Year: 2021

description: Purpose: Taurodontism was thought to be associated mainly with oro-facial syndromes but studies in normal Chinese and Brazilian adult populations have shown that this trait is relatively common. We hypothesize that taurodontism is a variation of normal root morphology that may be present in an adolescent population as an incidental finding. Methods: Digital dental panoramic radiographs (DPRs) taken of 124 adolescents aged between 15 and 20 years old (male: female; 59:65), attending the University of British Columbia’s Faculty of Dentistry Clinic between July 2006 and June 2019 were examined. Unrestored first and second permanent molars with closed apices were measured digitally and a taurodont ratio index was obtained using the Shifman and Chanannel criteria. Results: The total number of teeth examined was 992 and the proportion of taurodont teeth was 16.6%. Of the 124 cases, 68 (54.8%) had at least one taurodont tooth. There were 43 cases with bilateral taurodont teeth. Taurodontism had a higher predilection for females (63.1%) as compared to males (45.8%). This difference was significant for all molars with a P value ranging from P = .003 to P = .043, where P < .05, except for the upper left second permanent molar (tooth #27) and the lower left second permanent molar (tooth #37). The extent of taurodontism was mostly mild. Conclusions: Our results suggest that mild taurodontism is relatively common in the local adolescent population similar to what was reported elsewhere. The ability to identify these teeth and diagnose them early can help inform treatment planning decisions.

description: The fate of ionizing radiation is vital for understanding cosmic ionization, energy budgets in the interstellar and intergalactic medium, and star formation rate indicators. The low observed escape fractions of ionizing radiation have not been adequately explained, and there is evidence that some starbursts have high escape fractions. We examine the spectral energy distributions of a sample of local star-forming galaxies, containing thirteen local starburst galaxies and ten of their ordinary star-forming counterparts, to determine if there exist significant differences in the fate of ionizing radiation in these galaxies. We find that the galaxy-to-galaxy variations in the SEDs is much larger than any systematic differences between starbursts and non-starbursts. For example, we find no significant differences in the total absorption of ionizing radiation by dust, traced by the 24um, 70um, and 160um MIPS bands of the Spitzer Space Telescope, although the dust in starburst galaxies appears to be hotter than that of non-starburst galaxies. We also observe no excess ultraviolet flux in the GALEX bands that could indicate a high escape fraction of ionizing photons in starburst galaxies. The small H-alpha fractions of the diffuse, warm ionized medium in starburst galaxies are apparently due to temporarily boosted H-alpha luminosity within the star-forming regions themselves, with an independent, constant WIM luminosity. This independence of the WIM and starburst luminosities contrasts with WIM behavior in non-starburst galaxies and underscores our poor understanding of radiation transfer in both ordinary and starburst galaxies.

description: Theory has predicted rich and very distinct physics for graphene devices with boundaries that follow either the armchair or zigzag crystallographic directions. A prerequisite to disclose this physics in experiment is to be able to produce devices with boundaries of pure chirality. Exfoliated flakes frequently exhibit corners with an odd multiple of 30°, which raised expectations that their boundaries follow pure zigzag and armchair directions. The predicted Raman behavior at such crystallographic edges however failed to confirm pure edge chirality. Here, we perform confocal Raman spectroscopy on hexagonal holes obtained after the anisotropic etching of prepatterned pits using carbothermal decomposition of SiO2. The boundaries of the hexagonal holes are aligned along the zigzag crystallographic direction and leave hardly any signature in the Raman map indicating unprecedented purity of the edge chirality. This work offers the first opportunity to experimentally confirm the validity of the Raman theory for graphene edges.

Τα προγράμματα σχολικών γευμάτων, παρουσιάζουν ιδιαίτερο ενδιαφέρον για τη βελτίωση της δημόσιας διατροφής επειδή προσεγγίζουν τα παιδιά σε πληθυσμιακή κλίμακα σε όλες τις κοινωνικοοικονομικές τάξεις και για πάνω από μια δεκαετία της ζωής τους, και επειδή οι διατροφικές συνήθειες των παιδιών είναι πιο εύπλαστες από αυτές των ενηλίκων. Μέσω της παροχής υγιεινών και βιώσιμων σχολικών γευμάτων διευρύνονται οι διατροφικές, κοινωνικές, πρακτικές, εκπαιδευτικές, οικονομικές, πολιτικές και πολιτιστικές προοπτικές και προκλήσεις. Τέλος, επισημαίνεται η ανάγκη για μακροπρόθεσμες παρεμβάσεις και αξιολογήσεις. Σε αυτές τις παρεμβάσεις είναι σημαντικός ο ρόλος του σχολικού νοσηλευτή, που προάγει και βελτιώνει την υγεία των μαθητών και ενημερώνει το προσωπικό και τους μαθητές για την διατροφή και τα οφέλη που προκύπτουν στην υγεία τους με την λήψη μέτρων για την προστασία του περιβάλλοντος.

description: The carrier density distributions in few-layer-graphene systems grown on the carbon face of silicon carbide can be altered by the presence of a scanning tunneling microscope (STM) tip used to probe top-layer electronic properties, and by a perpendicular magnetic field which induces well-defined Landau levels. Hartree approximation calculations in the perpendicular field case show that charge tends to rearrange between the layers so that the filling factors of most layers are pinned at integer values. We use our analysis to provide insight into the role of buried layers in recent few-layer-graphene STM studies and discuss the limitations of our model.

description: Context: Chemical abundances of light elements as beryllium in planet-host stars allow us to study the planet formation scenarios and/or investigate possible surface pollution processes. Aims: We present here an extension of previous beryllium abundance studies. The complete sample consists of 70 stars hosting planets and 30 stars without known planetary companions. The aim of this paper is to further assess the trends found in previous studies with less number of objects. This will provide more information on the processes of depletion and mixing of light elements in the interior of late type stars, and will provide possible explanations for the abundance differences between stars that host planets and "single" stars. Methods: Using high resolution UVES spectra, we measure beryllium abundances of 26 stars that host planets and 1 "single" star mainly using the lambda 3131.065 A Be II line, by fitting synthetic spectra to the observational data. We also compile beryllium abundance measurements of 44 stars hosting planets and 29 "single" stars from the literature, resulting in a final sample of 100 objects. Results: We confirm that the beryllium content is roughly the same in stars hosting planets and in "single" stars at temperatures Teff > 5700K. The sample is still small for Teff < 5500K, but it seems that the scatter in Be abundances of dwarf stars is slightly higher at these cooler temperatures. Conclusions: We search for distinctive characteristics of planet hosts through correlations of Be abundance versus Li abundance, age, metallicity and oxygen abundance. These could provide some insight in the formation and evolution of planetary systems, but we did not find any clear correlation.

description: An ab initio downfolding method is formulated to construct low-dimensional models for correlated electrons. In addition to the band downfolding by constrained random phase approximation formulated for 3D models, screening away from the target layer (chain) is further involved. Eliminating the off-target degrees of freedom, namely, dimensional downfolding yields ab initio low-dimensional models. The method is applied to derive a 2D model for a layered superconductor LaFeAsO, where the interlayer screening crucially makes the effective interaction short ranged and reduces the onsite Coulomb interactions by 10-20 \% from the 3D model for the 5 iron-3d orbitals.

Axion quark nugget dark matter model : developments in model building and observations
Creators: name: Ge, Shuailiang
Publisher: name: University of British Columbia
Year: 2021

description: The axion quark nugget (AQN) model was initially proposed with the motivation to explain the observed similarity between the visible and dark matter abundances in the Universe. AQNs are dense objects made of standard model quarks in color superconducting (CS) phase. AQNs can be made of matter as well as antimatter. Matter AQNs and antimatter AQNs together form the dark matter, while the disparity between them will lead to the observed matter-antimatter asymmetry. Thus, the similarity between visible and dark matter abundances can be naturally explained since they have the same origin in the AQN framework. This thesis focuses on recent developments in model building and some potential observational evidence of AQNs. First, we show how the coherent nonzero axion field in the early Universe generates the disparity between matter and antimatter AQNs. Then, we calculate the real-time evolution of an AQN from its initial state as a closed axion domain wall with baryon charge trapped inside to its final CS state. Next, we show that for the most part of axion parameter space, AQNs are the dominant part of dark matter compared to the contribution of the free axions from the misalignment mechanism. After that, we calculate the size distribution of AQNs based on percolation theory. We also demonstrate that after formation, the size distribution can survive the subsequent evolution in the early Universe. Finally, we study potential observational evidence of the AQN model, focusing on the following two phenomena: the impulsive radio events in quiet solar corona recorded by the Murchison Widefield Array and the seasonal variation of the near-Earth X-ray background observed by the XMM-Newton observatory.

description: Irradiation with high energy photons (10.2 - 11.8 eV) was applied to small diamondoids isolated in solid rare gas matrices at low temperature. The photoproducts were traced via UV absorption spectroscopy. We found that upon ionization the smallest of these species lose a peripheral H atom to form a stable closed-shell cation. This process is also likely to occur under astrophysical conditions for gas phase diamondoids and it opens the possibility to detect diamond-like molecules using their rotational spectrum since the dehydrogenated cations possess strong permanent dipole moments. The lowest-energy electronic features of these species in the UV were found to be rather broad, shifting to longer wavelengths with increasing molecular size. Calculations using time-dependent density functional theory support our experimental findings and extend the absorption curves further into the vacuum ultraviolet. The complete sigma - sigma* spectrum displays surprisingly strong similarities to meteoritic nanodiamonds containing 50 times more C atoms.

description: Die vorliegende Arbeit beschäftigt sich mit der gleichmäßigen Auslastung eines Ballungs-raums durch die Verschiebung der Schulanfangszeiten. Ein solcher Ballungsraum entstehtimmer dann, wenn sich viele Menschen gleichzeitig, meist nah beeinander, innerhalb eines Sytems bewegen. Insbesondere entsteht ein solcher Ballungsraum bei einem sogenannten Schülertransportproblem, d.h. der Aufgabe, Schüler innerhalb eines Systems zu einer bestimmten Zeit zu ihrer Schule zu transportieren. Die Staffelung der Schulanfangszeiten bietet eine Möglichkeit, dieses hohe Personenaufkommen gezielt zu kontrollieren und zu optimieren. Die gleichmäßigere Auslastung eines Systems beeinflusst auch die Belastung im öffentlichen Nahverkehr. Im Gegensatz zur Schaffung neuer Alternativen können so die vorhandenen Kapazitäten effizienter eingesetzt werden, ohne das Angebot zu reduzieren. Durch das geringere punktuelle Aufkommen von Fahrgästen kann der zur Verfügung stehende Fuhrpark wirksamer genutzt werden. Zusätzlich machen die zu den Stoßzeiten entlasteten Busse und Bahnen den öffentlichen Personennahverkehr für andere Zielgruppen attraktiver. Im Rahmen dieser Arbeit wurde ein gemischt-ganzzahliger Ansatz zur Realisation dieser Aufgabe entwickelt. In Kapitel 1 wird zunächst ein Überblick über verschiedene Betrachtungsweisen und Modelle für Schülertransporte und der Optimierung von Personenaufkommen gegeben, Kapitel 2 widmet sich den notwendigen mathematischen Grundlagen, die für den Ansatz wichtig sind. Im Anschluss werden die Modelle konzipiert und erläutert. Die Ergebnisse werden dargestellt und analysiert, worauf abschließend ein Ausblick über die behandelte Problematik folgt.

description: Optimization to identify the global minimum energy conformation sequence in in silico enzyme design is computationally non-deterministic polynomial-time (NP)-hard, with the search time growing exponentially as the number of design sites increases. This drawback forces the modeling of protein-ligand systems to adopt discrete amino acid rotamers and ligand conformers, as well as continuum solvent treatment of the environment; however, such compromises produce large numbers of false positives in sequence selection. In this report, cephalosporin acylase, which catalyzes the hydrolytic reaction of cephalosporin C to 7-aminocephalosporanic acid, was used to investigate the dynamic features of active-site-transition-state complex structures using molecular dynamics (MD) simulations to potentially eliminate false positives. The molecular docking between cephalosporin C and wild type acylase N176 and its eight mutants showed that the rate-limiting step in the hydrolytic reaction of cephalosporin C is the acylation process. MD simulations of the active-site-transition-state complex structures of the acylation processes for N176 and its eight mutants showed that the geometrical constraints between catalytic residues and small molecule transition states are always well maintained during the 20 ns simulation for mutants with higher activities, and more hydrogen bonds between binding residues and functional groups of the ligand side chain in the active pocket are formed for mutants with higher activities. The conformations of the ligand transition states were changed greatly after the simulation. This indicates that the hydrogen bond network between the ligand and protein could be improved to enhance the activity of cephalosporin C acylase in subsequent design. © 2014 Springer-Verlag.
