description: Elastic neutron scattering studies of an optimized LaFeAsO single crystal reveal that upon cooling, an onset of the tetragonal (T)-to-orthorhombic (O) structural transition occurs at $T_\texttt{S} \approx 156$ K, and it exhibits a sharp transition at $T_\texttt{P} \approx 148$ K. We argue that in the temperature range $T_\texttt{S}$ to $T_\texttt{P}$, T and O structures may dynamically coexist possibly due to nematic spin correlations recently proposed for the iron pnictides, and we attribute $T_\texttt{P}$ to the formation of long-range O domains from the finite local precursors. The antiferromagnetic structure emerges at $T_\texttt{N} \approx 140$ K, with the iron moment direction along the O \emph{a} axis. We extract the iron magnetic form factor and use the tabulated $\langle j_0\rangle$ of Fe, Fe$^{2+}$ and Fe$^{3+}$ to obtain a magnetic moment size of $\sim$0.8 $μ_\texttt{B}$ at 9.5 K.

description: We report on a computer simulation study of a Lennard-Jones liquid confined in a narrow slit pore with tunable attractive walls. In order to investigate how freezing in this system occurs, we perform an analysis using different order parameters. Although some of the parameters indicate that the system goes through a hexatic phase, other parameters do not. This shows that to be certain whether a system has a hexatic phase, one needs to study not only a large system, but also several order parameters to check all necessary properties. We find that the Binder cumulant is the most reliable one to prove the existence of a hexatic phase. We observe an intermediate hexatic phase only in a monolayer of particles confined such that the fluctuations in the positions perpendicular to the walls are less then 0.15 particle diameters, i. e. if the system is practically perfectly 2d.
title: Single Image Super-Resolution for SAR Images

description: Single image Super-Resolution (SR) is a method to get a high-resolution image out of a single Low-Resolution (LR) image. SR is used in different domains, such as medical imaging, satellite imaging, and security imaging. Using SR compared to LR images speeds up training convergence and boosts recognition and segmentation accuracy. Apart from increasing the resolution of LR images, SR is able to denoise. Given the image acquisition hardware, there are physical restrictions on the image quality and resolution.SR helps overcome those limitations. This work focuses on the application of SR for Synthetic Aperture Radar (SAR) C-Band images captured by the Sentinel-1 satellites of the Copernicus Mission conducted by the European Space Agency. Earth Observation (EO) tasks, such as land cover estimation, detection of oil spills, land surface temperature,and soil moisture depend on the quality of the given remote sensing images. LR and noise impairs the underlying models, therefore SR is significant for earth science. This thesis investigates state-of-the-art SR approaches on SAR C-band images based on deep neural networks. An EO task for pixel-wise land cover segmentation is proposed in order to assess the suitability of SR for SAR images. Results of upscaling SAR images by a factor of 2 or 4 are evaluated based on image quality metrics (PSNR, SSIM) and an EO segmentation model. Furthermore, it is assessed if the SR methods can handle unseen temporal and spatial conditions and if adversarial training can further enhance the results.The final evaluation shows that SR for SAR C-band images is viable for upscaling by a factor of 2 and that unseen temporal and spatial conditions are manageable. In contrast,for SR by a factor of 4 to handle unseen temporal and spatial conditions, additional effort (re-training the EO model on the SR images) is required. Results indicate that adversarialtraining can improve both classification and image quality metrics. By keeping only the LR images, SR by a factor of 2 or 4 can reduce the necessary storage by a ratio of 4 or16, respectively. This work lays the ground for future research in the field of single image SR for SAR C-band images.

description: We present observations of a very massive galaxy at z=1.82 which show that its morphology, size, velocity dispersion and stellar population properties that are fully consistent with those expected for passively evolving progenitors of today's giant ellipticals. These findings are based on a deep optical rest-frame spectrum obtained with the Multi-Object InfraRed Camera and Spectrograph (MOIRCS) on the Subaru telescope of a high-z passive galaxy candidate (pBzK) from the COSMOS field, for which we accurately measure its redshift of z=1.8230 and obtain an upper limit on its velocity dispersion sigma_star<326 km/s. By detailed stellar population modeling of both the galaxy broad-band SED and the rest-frame optical spectrum we derive a star-formation-weighted age and formation redshift of t_sf~1-2 Gyr and z_form~2.5-4, and a stellar mass of M_star~(3-4)x10^{11} M_sun. This is in agreement with a virial mass limit of M_vir<7x10^{11}M_sun, derived from the measured sigma_star value and stellar half-light radius, as well as with the dynamical mass limit based on the Jeans equations. In contrast with previously reported super-dense passive galaxies at z~2, the present galaxy at z=1.82 appears to have both size and velocity dispersion similar to early-type galaxies in the local Universe with similar stellar mass. This suggests that z~2 massive and passive galaxies may exhibit a wide range of properties, then possibly following quite different evolutionary histories from z~2 to z=0.

description: Contexte : Le vieillissement de la population est en constante augmentation. Avec celui-ci accroît également le nombre de cas de démence et les besoins en soins médicaux. Le placement en établissement médico-social (EMS) est souvent inévitable pour les personnes atteintes de démence. Cette transition est difficile, tant pour le résident que pour sa famille, et peut devenir une source de tension. La qualité du partenariat entre l’équipe soignante et les familles est pourtant un facteur clé de réussite de l’adaptation à cette nouvelle situation. Objectifs : Explorer, à l’aide d’études primaires et de la théorie de McGill, les facilitateurs et les obstacles en jeu dans la construction d’un partenariat harmonieux entre la famille et les soignants. Méthode : Rechercher et analyser sept études primaires sur les bases de données de PUBMED, CINAHL et Google Scholar. Le cadre théorique de McGill permettra de mettre les résultats en perspective. Résultats : Il faut privilégier un environnement favorable au partenariat et à la collaboration. En effet, les caractéristiques et besoins des résidents et de leur famille sont variables et évolutifs. La communication est un élément central dans ce processus. Les obstacles et les facilitateurs en jeu dans la construction d’un partenariat harmonieux entre le personnel soignant et la famille ont été identifiés et plusieurs recommandations sont proposées. Néanmoins, les articles présentés dans ce travail sont exploratoires, qualitatifs et les échantillons sélectionnés étaient limités. Des études plus approfondies sont nécessaires.

description: It is shown that the violation of the positiveness of the entropy due to the Casimir-Lifshitz interaction claimed in several papers is an artifact related to an improper interpretation of the "Casimir entropy", which actually is a difference of two positive terms. It is explained that at definite condition this "Casimir entropy" must be negative. A direct derivation of the low temperature behavior of the surface entropy of a metallic surface in conditions of the anomalous skin effect is given and singular temperature dependency of this quantity is discussed. In conclusion a hydrodynamic example of the entropy of a liquid film is considered. It occurs that the entropy of a film of finite thickness and a liquid half-space behave differently at T tends to 0.

Reaching out : help-seeking behaviours among professional male ice hockey athletes
Creators: name: Crawford, Kaitlin Louise
Publisher: name: University of British Columbia
Year: 2021

description: In the last decade, a number of former National Hockey League (NHL) players died by suicide and overdose. In response to these tragic deaths, the NHL initiated several community-level mental health awareness initiatives (e.g., Hockey Talks). However, less is known about the current state of mental health and wellbeing support for the athletes who work and play in professional ice hockey leagues. Help-seeking is an integral first step for individuals and athletes to access the care and support they need to cope and manage their mental health and other stressors. To date, there have been no studies that have examined help-seeking behaviours and processes in professional male ice hockey. A thematic analysis of semi-structured interviews with 19 current and recently retired (retired within 5 years of interview) professional male ice hockey was conducted to explore their experiences with help-seeking over the course of their respective careers. To contextual the athletes’ help-seeking experiences participants described different stressors they encountered at the three major phases of their careers (1) pre-professional, (2) professional, and (3) following retirement. Four main higher-order themes were identified in relation to help-seeking experiences among ice hockey athletes. First, barriers to help-seeking describes elements that prevented or restricted athletes from engaging in help-seeking. Second, facilitators to help-seeking describe elements that encouraged or enabled potential help-seeking. Third, sources of support correspond to the different individuals and programs that participants sought help from or were offered support over the course of their careers. Finally, the different coping strategies and self-management techniques that athletes used, either individually or with their sources of support, are outlined. Findings suggest that help-seeking is a developmental process that is informed by cultural aspects of professional ice hockey.

Broad iron emission lines in Seyfert Galaxies - re-condensation of gas onto an inner disk below the ADAF

description: Recent observations of Seyfert 1 AGN with Chandra, XMM-Newton and Suzaku revealed broad iron K_alpha emission lines, some relativistically blurred. For galactic black hole X-ray binaries XMM-Newton spectra during hard state also reveal the presence of a relativistic iron emission line and a thermal component, interpreted as an indication for a weak inner cool accretion disk underneath a hot corona. These thermal components were found after the transition from soft to hard spectral state and can be understood as sustained by re-condensation of gas from an advection-dominated flow (ADAF) onto the disk. In view of the similarity of accretion flows around stellar mass and supermassive black holes we discuss whether the broad iron emission lines in Seyfert 1 AGN can be understood as arising from a similar accretion flow geometry. We derive Eddington-scaled accretion rates for Seyfert galaxies with strong lines in samples of Miller (2007) and Nandra et al. (2007). For the evaluation we use the observed X-ray luminosity, bolometric corrections and black hole masses from literature, most values taken from Fabian and Vasudevan (2009). Rates derived are less than 0.1 of the Eddington rate for more than half of the sources. For 10^7 to 10^8 solar mass black holes in Seyfert 1 AGN this limit corresponds to 0.01 to 0.2 solar masses per year. Our investigation shows that for quite a number of Seyfert AGN in hard spectral state iron emission lines can arise from an inner weak disk surrounded by an ADAF as predicted by the re-condensation model. Some of the remaining sources with higher accretion rates may be in a spectral state comparable to the "very high" state of LMXBs. (abridged)

Being blind and belonging in academia
Creators: name: Bulk, Laura Yvonne
Publisher: name: University of British Columbia
Year: 2021

description: Belonging is an essential human need. Developing a sense of belonging is important for people for whom academia is a place of learning, teaching, and employment. Academia – also known as educational institutions, higher education, post-secondary, college, or university – is a site of particular interest given the privilege engagement in this environment may imbue on individuals and communities. Moreover, academia is also problematic from the perspective of disabled people due to the ableist expectations embedded within it. Academia, and developing a sense of belonging there, may be particularly important for people from equity-seeking groups, including blind people. The general topic of this dissertation is an exploration of belonging in academia, from non-blind and blind perspectives. Following the introduction, chapter 2 presents a model – the Belonging in Academia Model - that explicates how sense of belonging develops in academia through five dimensions: affiliation, familiarity, acceptance, trusting connections & interdependent relationships, and equity. The dissertation goes on to examine blind and partially blind peoples’ experiences of belonging and non-belonging in academia, elucidating key nuances such as the importance of interdependence, feeling like a burden, and needing to perform as a disabled person. In chapter 3 this dissertation highlights scholarly teaching in the form of a workshop designed using research-based theatre as an affective pedagogical tool. Finally, preceding the conclusion, chapter 4 shares a brief exploration of doing ‘insider’ research as a blind scholar with blind people.

description: HH 110 is a rather peculiar Herbig-Haro object in Orion that originates due to the deflection of another jet (HH 270) by a dense molecular clump, instead of being directly ejected from a young stellar object. Here we present new results on the kinematics and physical conditions of HH 110 based on Integral Field Spectroscopy. The 3D spectral data cover the whole outflow extent (~4.5 arcmin, ~0.6 pc at a distance of 460 pc) in the spectral range 6500-7000 Å. We built emission-line intensity maps of H$α$, [NII] and [SII] and of their radial velocity channels. Furthermore, we analysed the spatial distribution of the excitation and electron density from [NII]/H$α$, [SII]/H$α$, and [SII] 6716/6731 integrated line-ratio maps, as well as their behaviour as a function of velocity, from line-ratio channel maps. Our results fully reproduce the morphology and kinematics obtained from previous imaging and long-slit data. In addition, the IFS data revealed, for the first time, the complex spatial distribution of the physical conditions (excitation and density) in the whole jet, and their behaviour as a function of the kinematics. The results here derived give further support to the more recent model simulations that involve deflection of a pulsed jet propagating in an inhomogeneous ambient medium. The IFS data give richer information than that provided by current model simulations or laboratory jet experiments. Hence, they could provide valuable clues to constrain the space parameters in future theoretical works.

description: Dense and cold clouds seem to populate the broad line region surrounding the central black hole in AGNs. These clouds could interact with the AGN jet base and this could have observational consequences. We want to study the gamma-ray emission produced by these jet-cloud interactions, and explore under which conditions this radiation would be detectable. We investigate the hydrodynamical properties of jet-cloud interactions and the resulting shocks, and develop a model to compute the spectral energy distribution of the emission generated by the particles accelerated in these shocks. We discuss our model in the context of radio-loud AGNs, with applications to two representative cases, the low-luminous Centaurus A, and the powerful 3C 273. Some fraction of the jet power can be channelled to gamma-rays, which would be likely dominated by synchrotron self-Compton radiation, and show typical variability timescales similar to the cloud lifetime within the jet, which is longer than several hours. Many clouds can interact with the jet simultaneously leading to fluxes significantly higher than in one interaction, but then variability will be smoothed out. Jet-cloud interactions may produce detectable gamma-rays in non-blazar AGNs, of transient nature in nearby low-luminous sources like Cen A, and steady in the case of powerful objects of FR II type.

description: Let $G=G(d)$ be a random graph with a given degree sequence $d$, such as a random $r$-regular graph where $r\ge 3$ is fixed and $n=|G|\to\infty$. We study the percolation phase transition on such graphs $G$, i.e., the emergence as $p$ increases of a unique giant component in the random subgraph $G[p]$ obtained by keeping edges independently with probability $p$. More generally, we study the emergence of a giant component in $G(d)$ itself as $d$ varies. We show that a single method can be used to prove very precise results below, inside and above the `scaling window' of the phase transition, matching many of the known results for the much simpler model $G(n,p)$. This method is a natural extension of that used by Bollobas and the author to study $G(n,p)$, itself based on work of Aldous and of Nachmias and Peres; the calculations are significantly more involved in the present setting.

Strength prediction with FEA

description: With composite materials showing extensive growth in aerospace, automotive, medical, energy, and other sectors, it is paramount that engineers understand the key differences between “classical” materials, such as steel, aluminum, and titanium (isotropic), and composite materials (anisotropic) when designing. Carbon fiber reinforced polymers (CFRPs) are among the most used composites in industries. Benefits of CFRPs include higher strength- and stiffness-to-weight ratios, established material supply, chemical resistance, and being biologically inert. However, CFRPs, like many composites, can fail in catastrophic ways with no indication of failure. As such, understanding the material and using modern tools, such as finite element analysis (FEA), is critical in ensuring the high standard of safety required by the industries which most use composites. This report has two major sections, both focusing on the modeling of CFRPs using the FEA package ANSYS. The first major section focuses on the development of an add-on program to the engineering curriculum, which attempts to introduce ANSYS FEA, specifically for the Composites Design & Manufacturing class currently taught by Dr. Mehran Tehrani. Through a series of video tutorials and two assignments, I teach students how to apply the theoretical knowledge obtained through the class into modeling and understanding mechanisms of failure in composites. I additionally branch into common techniques that accompany FEA, such as verification, validation, and mesh convergence studies. The second major section focuses on my research work in the strength prediction of composite materials. Through using ANSYS ACP and ANSYS Mechanical, I develop finite element models that simulate ASTM D7264, a testing standard for 3-point bending tests of fiber reinforced polymer composites. I develop a model to predict the flexural strength and verify and validate the model using beam theory, as well as external experimental data. Finally, I evaluate several failure criteria in composites, and draw conclusions on their performance when predicting flexural strength of select CFRP systems.

description: Recently it has become apparent that proto-stellar-like outflow activity extends to the brown dwarf (BD) mass regime. While the presence of accretion appears to be the common ingredient in all objects known to drive jets fundamental questions remain unanswered. The more prominent being the exact mechanism by which jets are launched, and whether this mechanism remains universal among such a diversity of sources and scales. To address these questions we have been investigating outflow activity in a sample of protostellar objects that differ considerably in mass and mass accretion rate. Central to this is our study of brown dwarf jets. To date Classical T Tauri stars (CTTS) have offered us the best touchstone for decoding the launching mechanism. Here we shall summarise what is understood so far of BD jets and the important constraints observations can place on models. We will focus on the comparison between jets driven by objects with central mass < 0.1M \odot and those driven by CTTSs. In particular we wish to understand how the the ratio of the mass outflow to accretion rate compares to what has been measured for CTTSs.

description: Momentum space of a gapped quantum system is a metric space: it admits a notion of distance reflecting properties of its quantum ground state. By using this quantum metric, we investigate geometric properties of momentum space. In particular, we introduce a non-local operator which represents distance square in real space and show that this corresponds to the Laplacian in curved momentum space, and also derive its path integral representation in momentum space. The quantum metric itself measures the second cumulant of the position operator in real space, much like the Berry gauge potential measures the first cumulant or the electric polarization in real space. By using the non-local operator and the metric, we study some aspects of topological phases such as topological invariants, the cumulants and topological phase transitions. The effect of interactions to the momentum space geometry is also discussed.

Nonlinear analysis of irregularities/discontinuities in high-rise concrete shear wall buildings
Creators: name: Mahmoodi, Maryam
Publisher: name: University of British Columbia
Year: 2021

description: State-of-the-art nonlinear analysis was used to investigate three different types of irregularities or discontinuities in high-rise concrete shear wall buildings. The objective was to develop knowledge that will assist practicing engineers who design buildings. Overhanging wall discontinuity due to the wall above being longer than the wall below creates significant amplification of concrete compression strains immediately below the overhang. While the strains are highly nonlinear, the results of the current study were used to develop simple amplification factors for estimating the nonlinear strain increases from the results of linear finite element analysis, which can be done by practicing engineers. A simple safe limit for the maximum compression strain in a wall below an overhang determined from linear analysis is 0.001 in order to limit the nonlinear vertical compression strain in the zone below the overhang to 0.004. A discontinuity in lateral stiffness of building occurs at grade level where the concrete diaphragms connect tower walls to foundation walls or at the top of podium levels. In design practice, these diaphragms are usually modelled as linear elastic members, and the choice of effective stiffness significantly influences how much force will go into the backstay force path. The effect of membrane forces on the flexibility of concrete diaphragms was investigated and a range of simplified models was presented. The nonlinear models provide a more accurate estimate of the diaphragm stiffness, while the simple upper and lower-bound (constant) stiffness models are much easier to use in practice. The influence of out-of-plane bending of the diaphragms on reducing membrane stiffness of the diaphragms was also investigated. Sloped-column Irregularity is a new type of irregularity defined in the 2020 National Building Code of Canada for the seismic design of buildings as an outcome of the current study. Nonlinear time history analysis was used to investigate how the differential horizontal movement at the top and bottom of sloped columns causes vertical accelerations of the building mass. A simplified procedure was developed to account for the possible range of member stiffnesses and to account for vertical ground motions in a simplified way.

description: We explore the nature of ultraluminous X-ray sources through detailed investigations of their spectral shape using some of the highest quality data available in the XMM-Newton public archives. Phenomenological models allow us to characterise their spectra, while more 'physically-motivated' models enable us to explore the physical processes underlying these characteristics. These physical models imply the presence of extreme (probably super-Eddington) accretion on to stellar mass black holes.

Non-perturbative Corrections to Particle Production from Coherent Oscillation

description: We investigate particle production from coherent oscillation by using the method based on the Bogolyubov transformation. Especially, we study the case when the amplitude of the oscillation and also the coupling constants with the oscillating field are small in order to avoid the non-perturbative corrections from the broad parametric resonance. We derive the expressions for the distribution functions and the number densities of produced particles at the leading order of coupling constant. It is, however, found that these results fail to describe the exact particle production eventually due to the non-perturbative effects even if the coupling constants are small. We then introduce a simple method to handle with such corrections, i.e., the time averaging method. It is shown that this method successfully provides the evolution of the occupation numbers of the growing mode. Further, we point out that the approximate results by this method satisfy the exact scaling properties coming from the periodicity of the coherent oscillation.

Intertwining Relations for the Deformed D1D5 CFT

description: The Higgs branch of the D1D5 system flows in the infrared to a two-dimensional N=(4,4) SCFT. This system is believed to have an "orbifold point" in its moduli space where the SCFT is a free sigma model with target space the symmetric product of copies of four-tori; however, at the orbifold point gravity is strongly coupled and to reach the supergravity point one needs to turn on the four exactly marginal deformations corresponding to the blow-up modes of the orbifold SCFT. Recently, technology has been developed for studying these deformations and perturbing the D1D5 CFT off its orbifold point. We present a new method for computing the general effect of a single application of the deformation operators. The method takes the form of intertwining relations that map operators in the untwisted sector before application of the deformation operator to operators in the 2-twisted sector after the application of the deformation operator. This method is computationally more direct, and may be of theoretical interest. This line of inquiry should ultimately have relevance for black hole physics.

Numerical study of magnetization processes in rare-earth tetraborides

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: We present a simple model for a description of magnetization processes in rare-earth tetraborides. The model is based on the coexistence of two subsystems, and namely, the spin subsystem described by the Ising model and the electronic subsystem described by the Falicov-Kimball model on the Shastry-Sutherland lattice (SSL). Moreover, both subsystems are coupled by the anisotropic spin-dependent interaction of the Ising type. We have found, that the switching on the spin-dependent interaction ($J_z$) between the electron and spin subsystems and taking into account the electron hopping on the nearest ($t$) and next-nearest ($t'$) lattice sites of the SSL leads to a stabilization of new magnetization plateaus. In addition, to the Ising magnetization plateau at $m^{sp}/m_s^{sp}=1/3$ we have found three new magnetization plateaus located at $m^{sp}/m_s^{sp}=1/2$, 1/5 and 1/7 of the saturated spin magnetization $m_s^{sp}$. The ground-states corresponding to magnetization plateaus have the same spin structure consisting of parallel antiferromagnetic bands separated by ferromagnetic stripes.

description: The association of young T Tauri stars, MBM12A, indicates that L1457 was forming stars not too long ago. With our study we want to find out whether or not there are still signs for ongoing star formation in that cloud. Using the Max-Planck-Millimeter-Bolometer MAMBO at the IRAM 30m telescope we obtained a map of about 8' by 8' centered on L1457 in the dust continuum emission at 230 GHz. Towards the most intense regions in our bolometer map we obtained spectra at high angular resolution in the CS (2-1) and the N2H+(1-0) lines using the IRAM 30m telescope. We find that the cold dust in L1457 is concentrated in several small cores with high H2 column densities and solar masses. The density profiles of the cores are inconsistent with a sphere with constant density. These cores are closer to virial equilibrium than the cloud as a whole. Data from the VLA and Spitzer archives reveal two point sources in the direction of one dust core. One of the sources is probably a distant quasar, whereas the other source is projected right on a local maximum of our dust map and shows characteristics of a protostellar object.

"Io continuo così": il vissuto personale e la coerenza testuale nell'invenzione di storie alla SI
Creators: name: Martignoni, Melissa
Publisher: name: Scuola Universitaria della Svizzera Italiana (SUPSI)
Year: 2014

description: Lo scopo di questo lavoro è stato quello di osservare se e come i bambini (III livello di Scuola dell’Infanzia) introducono il loro vissuto personale (con l’aiuto di un oggetto portato da casa) nella continuazione di una fiaba classica (Mignolina), interrotta in un punto significativo. In particolare, si è voluto osservare se i vissuti sono stati introdotti con coerenza nella struttura e nel contenuto della storia, e se i bambini hanno attuato strategie narrative particolari. La raccolta dati è stata organizzata su quattro incontri nei quali, attraverso disegni e colloqui individuali, sono state raccolte le informazioni rilevanti ai fini della ricerca. Ho potuto constatare che i bambini considerati sono stati in grado di staccarsi dalla dimensione egocentrica (tipica in questa fascia d’età) per entrare nel vivo della storia e della sua struttura, tessendo attorno alla fiaba, con modalità e procedure di coesione diverse, il loro finale. L’oggetto è diventato per alcuni una presenza “essenziale”, sotto forma di esperienza vissuta fondamentale per il contenuto e la coerenza della fiaba, mentre per altri “aggiuntiva”, più o meno rilevante per la narrazione, indipendente, però, dal vissuto. Sebbene il compito richiesto non sia stato semplice, l’attività si è mostrata utile e interessante per i bambini per “allenare” l’inventiva (raccontare a partire da uno stimolo) e cominciare a lavorare sulla costruzione coerente di una narrazione, all’interno di una cornice predefinita.
