description: We present a method for studying the proximity effect and the density structure around redshift z=2-3 quasars. It is based on the probability distribution of Lyman-alpha pixel optical depths and its evolution with redshift. We validate the method using mock spectra obtained from hydrodynamical simulations, and then apply it to a sample of 12 bright quasars at redshifts 2-3 observed with UVES at the VLT-UT2 Kueyen ESO telescope. These quasars do not show signatures of associated absorption and have a mean monochromatic luminosity of 5.4 10^{31} h^{-2} erg/s/Hz at the Lyman limit. The observed distribution of optical depth within 10 Mpc/h from the QSO is statistically different from that measured in the general intergalactic medium at the same redshift. Such a change will result from the combined effects of the increase in photoionisation rate above the mean UV-background due to the extra ionizing photons from the quasar radiation (proximity effect), and the higher density of the IGM if the quasars reside in overdense regions (as expected from biased galaxy formation). The first factor decreases the optical depth whereas the second one increases the optical depth, but our measurement cannot distinguish a high background from a low overdensity. An overdensity of the order of a few is required if we use the amplitude of the UV-background inferred from the mean Lyman-$α$ opacity. If no overdensity is present, then we require the UV-background to be higher, and consistent with the existing measurements based on standard analysis of the proximity effect.

Discrete embedded solitons

Subjects: subject: Pattern Formation and Solitons (nlin.PS)

description: We address the existence and properties of discrete embedded solitons (ESs), i.e., localized waves existing inside the phonon band in a nonlinear dynamical-lattice model. The model describes a one-dimensional array of optical waveguides with both the quadratic (second-harmonic generation) and cubic nonlinearities. A rich family of ESs was previously known in the continuum limit of the model. First, a simple motivating problem is considered, in which the cubic nonlinearity acts in a single waveguide. An explicit solution is constructed asymptotically in the large-wavenumber limit. The general problem is then shown to be equivalent to the existence of a homoclinic orbit in a four-dimensional reversible map. From properties of such maps, it is shown that (unlike ordinary gap solitons), discrete ESs have the same codimension as their continuum counterparts. A specific numerical method is developed to compute homoclinic solutions of the map, that are symmetric under a specific reversing transformation. Existence is then studied in the full parameter space of the problem. Numerical results agree with the asymptotic results in the appropriate limit and suggest that the discrete ESs may be semi-stable as in the continuous case.

description: We present a survey of MgII absorbing gas in the vicinity of 380 random galaxies, using 156 background quasi-stellar objects(QSOs) as absorption-line probes. The sample comprises 211 isolated (73 quiescent and 138 star-forming galaxies) and 43 non-isolated galaxies with sensitive constraints for both MgII absorption and Ha emission. The projected distances span a range from d=9 to 497 kpc, redshifts of the galaxies range from z=0.10 to 0.48, and rest-frame absolute B-band magnitudes range from $M_{\rm B}=-16.7$ to $-22.8$. Our analysis shows that the rest-frame equivalent width of MgII, $W_r$(2796), depends on halo radius($R_h$), $B$-band luminosity($L_{\rm B}$) and stellar mass ($M_{\rm star}$) of the host galaxies, and declines steeply with increasing $d$ for isolated, star-forming galaxies. $W_r$(2796) exhibits no clear trend for either isolated, quiescent galaxies or non-isolated galaxies. The covering fraction of MgII absorbing gas $\langle κ\rangle$ is high with $\langle κ\rangle\gtrsim 60$% at $<40$ kpc for isolated galaxies and declines rapidly to $\langle κ\rangle\approx 0$ at $d\gtrsim100$ kpc. Within the gaseous radius, $\langle κ\rangle$ depends sensitively on both $M_{\rm star}$ and the specific star formation rate inferred from Ha. Different from massive quiescent halos, the observed velocity dispersion of MgII gas around star-forming galaxies is consistent with expectations from virial motion, which constrains individual clump mass to $m_{\rm cl} \gtrsim 10^5 \,\rm M_\odot$ and cool gas accretion rate of $\sim 0.7-2 \,M_\odot\,\rm yr^{-1}$. We find no strong azimuthal dependence of MgII absorption for either star-forming or quiescent galaxies. Our results highlight the need of a homogeneous, absorption-blind sample for establishing a holistic description of chemically-enriched gas in the circumgalactic space.

Can we talk about sex? : an exploration of men seeking counselling with sex-related issues
Creators: name: Cave, Douglas G.
Publisher: name: University of British Columbia
Year: 2009

description: Human sexuality is constructed through social identities. The limitations resulting from socially constructed sexuality impede identity development and cohesion of the individual human condition. Men's sexual identity is bounded by these socially constructed limitations. The objective of this study was to interpret transcripts of audiotaped, semi-structured interviews exploring the experiences of 5 men who sought sex-related counselling. The understanding and interpretation of the interview transcripts ensues from extracting the core narrative, the 'move' of the narrative, and identifying both conjoint and disparate themes between and within the interviews. The findings suggest that men confront socially constructed shame, and their own reticence while being driven by an urgent need for help. Connecting with social and political support networks appears helpful with reauthoring their constructs and working through their presenting issues. These findings have implications for social workers, other counsellors and those who train them about working with men who seek sex-related counselling.

description: The dynamic partial differential equation (PDE) model governing longitudinal oscillations in magnetizable piezoelectric beams exhibits exponentially stable solutions when subjected to two boundary state feedback controllers. An analytically established exponential decay rate by the Lyapunov approach ensures stabilization of the system to equilibrium, though the actual decay rate could potentially be improved. The decay rate of the closed-loop system is highly sensitive to the choice of material parameters and the design of the state feedback amplifiers. This paper focuses on investigating the design of state feedback amplifiers to achieve a maximal exponential decay rate, which is essential for effectively suppressing oscillations in these beams. Through this design process, we explicitly determine the safe intervals of feedback amplifiers that ensure the theoretically found maximal decay rate, with the potential for even better rates. Our numerical results reaffirm the robustness of the decay rate within the chosen range of feedback amplifiers, while deviations from this range significantly impact the decay rate. To underscore the validity of our results, we present various numerical experiments.

description: Objects moving at high speed appear significantly blurred when captured with cameras. The blurry appearance is especially ambiguous when the object has complex shape or texture. In such cases, classical methods, or even humans, are unable to recover the object's appearance and motion. We propose a method that, given a single image with its estimated background, outputs the object's appearance and position in a series of sub-frames as if captured by a high-speed camera (i.e. temporal super-resolution). The proposed generative model embeds an image of the blurred object into a latent space representation, disentangles the background, and renders the sharp appearance. Inspired by the image formation model, we design novel self-supervised loss function terms that boost performance and show good generalization capabilities. The proposed DeFMO method is trained on a complex synthetic dataset, yet it performs well on real-world data from several datasets. DeFMO outperforms the state of the art and generates high-quality temporal super-resolution frames.

Explaining the new seaport competition
Creators: name: Walter, Nathan Andrew
Publisher: name: University of British Columbia
Year: 2009

description: In recent decades, competition has become an extremely prominent issue in the seaport industry due in large part to fundamental changes that have redefined the competitive environment. New technologies such as containerization and intermodalism are widely acknowledged to be the main factors forcing these changes, yet the broader role of more intense competition between seaports has been generally overlooked. This thesis develops a framework for examining these processes of change and uses it to explain how the new modes of shipping produced a "new" seaport competition. I deviate from the positivist-based "extensive" approach that dominates the body of research on seaports, and take instead an "intensive" approach grounded in the philosophy of realism. First, I theorize seaports as production-systems and competition as a process of managing strategic problems and solutions that are necessarily situated within a particular spatiotemporality. Second, I apply that theoretical framework to explain how the nature of competition between seaports has changed with the emergence of containerization and intermodalism. Third, I corroborate that explanation by presenting the results of interactive, minimally structured interviews with seaport officials from ports in Tacoma, Seattle, and Vancouver, on the issues of competition and change. The major finding is that containerization and intermodalism produced a "new" competition by transforming the temporal and spatial dimensions of the strategic problems for seaport production-systems in the realms of (1) customers/markets, (2) the seaport product, and (3) strategies. This research complements the existing literature by emphasizing the structures that have produced the change in seaport competition and examining the issue from the perspective of seaports rather than demand-side factors.

description: We investigate the effect of quenched surface charge disorder on electrostatic interactions between two charged surfaces in the presence of dielectric inhomogeneities and added salt. We show that in the linear weak-coupling regime (i.e., by including mean-field and Gaussian-fluctuations contributions), the image-charge effects lead to a non-zero disorder-induced interaction free energy between two surfaces of equal mean charge that can be repulsive or attractive depending on the dielectric mismatch across the bounding surfaces and the exact location of the disordered charge distribution.

description: We introduce models for viscoelastic materials, both solids and fluids, based on logarithmic stresses to capture the elastic contribution to the material response. The matrix logarithm allows to link the measures of strain, that naturally belong to a multiplicative group of linear transformations, to stresses, that are additive elements of a linear space of tensors. As regards the viscous stresses, we simply assume a Newtonian constitutive law, but the presence of elasticity and plastic relaxation makes the materials non-Newtonian. Our aim is to discuss the existence of weak solutions for the corresponding systems of partial differential equations in the nonlinear large-deformation regime. The main difficulties arise in the analysis of the transport equations necessary to describe the evolution of tensorial measures of strain. For the solid model, we only need to consider the equation for the left Cauchy-Green tensor, while for the fluid model we add an evolution equation for the elastically-relaxed strain. Due to the tensorial nature of the fields, available techniques cannot be applied to the analysis of such transport equations. To cope with this, we introduce the notion of charted weak solution, based on non-standard a priori estimates, that lead to a global-in-time existence of solutions for the viscoelastic models in the natural functional setting associated with the energy inequality.

description: When a hadron is probed at high energy, a nontrivial quantum entanglement entropy inside the hadron emerges due to the lack of complete information about the hadron wave function extracted from this measurement. In the high-energy limit, the hadron becomes a maximally entangled state, with a linear dependence of entanglement entropy on rapidity, as has been found in a recent analysis based on parton description. In this paper, we use an effective conformal field theoretic description of hadrons on the light cone to show that the linear dependence of the entanglement entropy on rapidity found in parton description is a general consequence of approximate conformal invariance and does not depend on the assumption of weak coupling. Our result also provides further evidence for a duality between the parton and string descriptions of hadrons.

description: Computer-aided detection, localisation, and segmentation methods can help improve colonoscopy procedures. Even though many methods have been built to tackle automatic detection and segmentation of polyps, benchmarking of state-of-the-art methods still remains an open problem. This is due to the increasing number of researched computer vision methods that can be applied to polyp datasets. Benchmarking of novel methods can provide a direction to the development of automated polyp detection and segmentation tasks. Furthermore, it ensures that the produced results in the community are reproducible and provide a fair comparison of developed methods. In this paper, we benchmark several recent state-of-the-art methods using Kvasir-SEG, an open-access dataset of colonoscopy images for polyp detection, localisation, and segmentation evaluating both method accuracy and speed. Whilst, most methods in literature have competitive performance over accuracy, we show that the proposed ColonSegNet achieved a better trade-off between an average precision of 0.8000 and mean IoU of 0.8100, and the fastest speed of 180 frames per second for the detection and localisation task. Likewise, the proposed ColonSegNet achieved a competitive dice coefficient of 0.8206 and the best average speed of 182.38 frames per second for the segmentation task. Our comprehensive comparison with various state-of-the-art methods reveals the importance of benchmarking the deep learning methods for automated real-time polyp identification and delineations that can potentially transform current clinical practices and minimise miss-detection rates.

Polarimetric observations of GRB 020813 already allowed to exclude a homogeneous jet for this event. We then present observations of faint/dark bursts, showing that some of them may be obscured by dust, while others are possibly just intrinsically dim.

description: We examine the adiabatic approximation in the study of a relativistic two-body problem with the gravitational radiation reaction. We recently pointed out that the usual metric perturbation scheme using a perturbation of the stress-energy tensor may not be appropriate for study of the dissipative dynamics of the bodies due to the radiation reaction. We recently proposed a possible approach to solve this problem with a linear black hole perturbation. This paper proposes a non-linear generalization of that method for a general application of this problem. We show that, under a specific gauge condition, the method actually allows us to avoid the gauge problem.

We write down the von Kármán-Howarth equations for this kind of turbulence, and consider the correlations corresponding to fully developed turbulence.

description: We develop a new structured compartmental model for the coevolutionary dynamics between susceptible and infectious individuals in heterogeneous SI epidemiological systems. In this model, the susceptible compartment is structured by a continuous variable that represents the level of resistance to infection of susceptible individuals, while the infectious compartment is structured by a continuous variable that represents the viral load of infectious individuals. We first formulate an individual-based model wherein the dynamics of single individuals is described through stochastic processes, which permits a fine-grain representation of individual dynamics and captures stochastic variability in evolutionary trajectories amongst individuals. Next we formally derive the mesoscopic counterpart of this model, which consists of a system of coupled integro-differential equations for the population density functions of susceptible and infectious individuals. Then we consider an appropriately rescaled version of this system and we carry out formal asymptotic analysis to derive the corresponding macroscopic model, which comprises a system of coupled ordinary differential equations for the proportions of susceptible and infectious individuals, the mean level of resistance to infection of susceptible individuals, and the mean viral load of infectious individuals. Overall, this leads to a coherent mathematical representation of the coevolutionary dynamics between susceptible and infectious individuals across scales. We provide well-posedness results for the mesoscopic and macroscopic models, and we show that there is excellent agreement between analytical results on the long-time behaviour of the components of the solution to the macroscopic model, the results of Monte Carlo simulations of the individual-based model, and numerical solutions of the macroscopic model.
title: Der Kulturbegriff im mehrsprachigen Literaturunterricht
Creators: name: Weber, Carmen
Year: 2023

description: Die vorliegende Masterarbeit wurde verfasst, um zu eruieren, wie Mehrsprachigkeit im österreichischen Schulsystem gelebt wird und wie ein Einsatz dieser im Literaturunterricht passieren kann, ohne einen diskriminierenden Kulturbegriff in den Vordergrund zu stellen. Im Alltag wird das Herkunftsland der Eltern oder das Geburtsland einer Person oft mit dem Kulturbegriff gleichgesetzt. In einem ausführlichen Theoriekapitel wurde allerdings belegt, dass der Begriff weit umfassender auszulegen ist. In einer darauf aufbauenden, schriftlichen Befragung gab eine 3. Klasse einer niederösterreichischen Mittelschule Auskunft darüber, welche Sprachen in ihrem familiären Umfeld gesprochen werden und wie weit diese Fähigkeiten bei ihnen fortgeschritten sind. Weiters wurde analysiert, in welchen Sprachen die Kinder gerne lesen können wollen und wie sie sich einen mehrsprachigen Unterricht vorstellen würden. Die Ergebnisse zeigen, dass die Kinder nicht mehrheitlich den Wunsch hegen, ihre Familiensprache zu fördern, sondern gerne in anderen Sprachen lesen können würden. Die Kinder sind interessiert daran, neue Sprachkenntnisse aufzubauen, zu denen bisher noch keine Verbindung bestand. Diese Information hilft Lehrpersonen dabei, ansprechende mehrsprachige Literatur zu finden, um die Lesemotivation der Jugendlichen zu erhöhen.

description: A wildland fire model based on semi-empirical relations for the spread rate of a surface fire and post-frontal heat release is coupled with the Weather Research and Forecasting atmospheric model (WRF). The propagation of the fire front is implemented by a level set method. Data is assimilated by a morphing ensemble Kalman filter, which provides amplitude as well as position corrections. Thermal images of a fire will provide the observations and will be compared to a synthetic image from the model state.

Origins of anomalously low Raman exponents in single-molecule magnets

description: The Raman exponent of single-molecular magnetic relaxation may take various unexpected values because of rich phonon spectrum and spin-phonon coupling of molecular crystals. We systematically examine the origins of different abnormalities, and clarify misunderstandings in the past, particularly the appropriateness of the fitting procedures for the exponents. We find that exponential laws raised by optical phonons can yield spurious power laws with low exponents. This observation indicates long-standing misunderstandings for origins of low Raman exponents in a large bulk of single-molecule magnets. Resulting from spin-lattice coupling with optical modes, presence of these exponents suggests the importance of the local dynamical environment for the magnetic relaxation in this regime.

title: Sprachsensibler Unterricht in österreichischen Lehrwerken für den Geschichteunterricht
Creators: name: Gamperl, Kristina
Year: 2023

description: Diese Arbeit beschäftigt sich mit der Wichtigkeit der sprachsensiblen Unterrichtsgestaltung, in Hinblick auf die heterogenen Klassenstrukturen und die sprachlichen Varietäten, die Schüler*innen mit in die Schule bringen. Das in Bildungsbereichen vertretene sprachliche Register der Bildungssprache stellt die Lerner*innen vor enorme Herausforderungen. Daher muss es ein Ziel für Lehrkräfte sein, Schüler*innen an die im Bildungskontext verwendeten sprachlichen Register heranzuführen und sich von dem Gedanken zu entfernen, das sprachliche Bildung nur eine Aufgabe des Sprachunterrichts sei. Anhand einer nicht repräsentativen Sprachstandserhebung wird aufgezeigt, dass vor allem auch Fachtexte in Schulbüchern einige Stolpersteine für Schüler*innen bereithalten, die im schlimmsten Fall dafür sorgen, dass Inhalte nicht ausreichend verstanden werden können. Auf Basis der Ergebnisse und in Hinblick auf aktuellere Ansätze und Konzepte der Sprachförderung wurde in weiterer Folge ein Förderkonzept erstellt, welches als Beispiel dafür dienen soll, wie sprachliche Bildung und Förderung im Fachunterricht unter Verwendung von Fachtexten am Beispiel von Geschichte, Sozialkunde und politische Bildung umgesetzt werden kann.
description: This thesis deals with the importance of language-sensitive lesson design, with regard to the heterogeneous class structures and linguistic varieties that students bring to school. The linguistic register of the language of education, which is represented in educational fields, poses enormous challenges for learners. Therefore, it must be a goal for teachers to introduce students to the linguistic registers used in the educational context and to move away from the idea that language education is only a task of language teaching. On the basis of a non-representative language level survey, it is shown that specialist texts in textbooks in particular have some stumbling blocks for pupils, which in the worst case ensure that content cannot be sufficiently understood. On the basis of the results and with regard to more up-to-date approaches and concepts of language support, a support concept was subsequently drawn up, which is intended to serve as an example of how language education and support in subject teaching can be implemented using specialist texts using the example of history, social studies and political education.

description: We determine the asymptotics of the block Toeplitz determinants $\det T_n(ϕ)$ as $n\to\infty$ for $N\times N$ matrix-valued piecewise continuous functions $ϕ$ with a finitely many jumps under mild additional conditions. In particular, we prove that $$
 \det T_n(ϕ) \sim G^n n^ΩE\quad {\rm as}\ n\to \infty, $$ where $G$, $E$, and $Ω$ are constants that depend on the matrix symbol $ϕ$ and are described in our main results. Our approach is based on a new localization theorem for Toeplitz determinants, a new method of computing the Fredholm index of Toeplitz operators with piecewise continuous matrix-valued symbols, and other operator theoretic methods. As an application of our results, we consider piecewise continuous symbols that arise in the study of entanglement entropy in quantum spin chain models.

description: Starting with a brief overview of trends in plant variety protection (PVP) in the UK since inception of PVP legislation, this paper assesses the strength of incentives for innovation provided by the PVP regime. We modify and extend models from the patent literature that attempt to infer the private value of innovations from the behaviour of titleholders in relation to the annual renewal of protection. Our results suggest that the average private return to protection from new wheat varieties is fairly modest and that the distribution of these returns is highly skewed. This implies that a large proportion of PVP certificates have very little economic value. The move towards stronger forms of protection for plant variety innovations and the (successful) clamour from the industry for imposition of royalties on farm-saved seed of protected varieties can be understood as a response to the declining returns from variety innovations in agricultural crops brought about by increasing competition and accelerated turnover of varieties. Anecdotal evidence regarding the declining viability of conventional plant breeding for agricultural crops in the UK is also supported by our results.
