description: Using data of nearby galaxies from the Sloan Digital Sky Survey we investigate whether stellar mass, central velocity dispersion, surface mass density, or the Sersic n parameter is best correlated with a galaxy's rest-frame color. Specifically, we determine how the mean color of galaxies varies with one parameter when another is fixed. When the stellar mass is fixed we see that strong trends remain with all other parameters, whereas residual trends are weaker when surface mass density, n, or velocity dispersion are fixed. Overall velocity dispersion is the best indicator of a galaxy's typical color, showing the largest residual color dependence when any of the other three parameters are fixed, and stellar mass is the poorest. Other studies have indicated that both the halo and black hole properties are better correlated with velocity dispersion than with stellar mass, surface mass density or Sersic n. Therefore, our results are consistent with a picture where a galaxy's star formation history and present star formation rate are determined to some significant degree by the current properties and assembly history of its dark matter halo and/or the feedback from its central super massive black hole.

description: The ground state of the quantum spin system kappa-(BEDT-TTF)2Cu2(CN)3 in which antiferromagnetically-interacting S=1/2 spins are located on a nearly equilateral triangular lattice attracts considerable interest both from experimental and theoretical aspects, because a simple antiferromagnetic order may be inhibited because of the geometrical frustration and hence an exotic ground state is expected. Furthermore, recent two reports on the ground state of this system have made it further intriguing by showing completely controversial results; one indicates the gapless state and the other gapped. By utilizing microscopic probe of muSR, we have investigated its spin dynamics below 0.1 K, unveiling its microscopically phase separated ground state at zero field.

Going beyond muscularity : developing a multidimensional measure of male body concerns
Creators: name: Rusticus, Shayna Ann
Publisher: name: University of British Columbia
Year: 2010

description: Until recently, concern with body shape and image has primarily been considered a female domain and body image concerns among men were all but ignored. Researchers are now beginning to address this gap in the literature, as evidenced by the rapid rise in the number of studies pertaining to male body image. However, there are currently only a limited number of body image measures available that attempt to tap male body image concern, with these measures predominantly focusing only on the drive for muscularity. As a result, these measures are likely excluding other aspects important to men’s body image. The purpose of the current dissertation was to develop a multidimensional measure of male body image, named the Multidimensional Male Body Concerns Questionnaire (MMBCQ), and determine whether it yields reliable scores and valid interpretations. This purpose was achieved through a series of three studies. The first study consisted of a qualitative investigation that identified nine major aspects of men’s bodies and appearance that are most important to their body image. The second study developed items to assess these nine dimensions. A pilot test then reduced the original 55 items to a total of 39 items, which assessed the dimensions of muscularity, body fat, youthfulness, body hair, and penis. The third study refined the MMBCQ to a total of 35 items and provided additional reliability and validity evidence for the MMBCQ subscales. This new measure will allow researchers to extend their understanding of the male body image construct beyond muscularity alone. Through the use of a mixed methods approach and a combination of CTT and IRT, this dissertation uses modern validity theory to provide a comprehensive model of test development and validation.

description: Here, we investigate the physical mechanisms that may enable squeezing a complex electromagnetic field distribution through a narrow and/or partially obstructed region with little amplitude and phase distortions. Following our recent works, such field manipulations may be made possible by a procedure in which the incoming wave is first "sampled" "pixel by pixel" using an array of metallic waveguides, and in a second step the energy corresponding to each individual pixel is "squeezed" through a very narrow channel filled with a permittivity-near zero material. In this work, we study in detail these processes in scenarios where the electromagnetic wave is compressed along a single direction of space, and present theoretical models that enable the analytical modeling of such phenomena. Full-wave results obtained with an electromagnetic simulator, demonstrate the possibility of compressing an incoming wave several folds through ultranarrow channels filled with silicon carbide. The "sampling and squeezing" concept may enable unparalleled control of electromagnetic waves in the nanoscale.

description: Topological phases are unique states of matter incorporating long-range quantum entanglement, hosting exotic excitations with fractional quantum statistics. We report a practical method to identify topological phases in arbitrary realistic models by accurately calculating the Topological Entanglement Entropy (TEE) using the Density Matrix Renormalization Group (DMRG). We argue that the DMRG algorithm naturally produces a minimally entangled state, from amongst the quasi-degenerate ground states in a topological phase. This proposal both explains the success of this method, and the absence of ground state degeneracy found in prior DMRG sightings of topological phases. We demonstrate the effectiveness of the calculational procedure by obtaining the TEE for several microscopic models, with an accuracy of order $10^{-3}$ when the circumference of the cylinder is around ten times the correlation length. As an example, we definitively show the ground state of the quantum $S=1/2$ antiferromagnet on the kagomé lattice is a topological spin liquid, and strongly constrain the full identification of this phase of matter.

Teacher self-efficacy and behaviour support in schools
Creators: name: Bennett, Joanna L.
Publisher: name: University of British Columbia
Year: 2011

description: This study examined the relations between implementation of a school-wide approach to behaviour, School-wide Positive Behaviour Support (SWPBS) and teacher self-efficacy. Twenty-two teachers from schools implementing SWPBS and 40 teachers from schools not implementing SWPBS completed a questionnaire measuring aspects of self-efficacy. Differences in ratings of self-efficacy were examined using multilevel modeling. Results showed that teachers at SWPBS schools reported significantly higher perceptions of teacher self-efficacy when controlling for school-level effects. Results are discussed in terms of implications for future research and practice.

description: In my dissertation, I explore how emotions operate under conditions of injustice. Specifically, my interest is in how one should deploy their emotions in order to combat patriarchally informed, affective ways of making sense of and responding to the social world. My dissertation consists of the following three papers. In the first paper, “Vindictive Anger,” I argue for two claims. First, that anger is not necessarily made morally worse whenever and to the extent that it involves a desire for payback. Second, that in certain cases, anger’s retributive component is precisely what moralizes the emotion. Victims of sexual violence, I argue, paradigmatically deploy their anger as a way of getting their transgressor or, in some cases, the broader moral community, to more fully understand, through affect, the wrongness of their action. One can see this occur in the anger expressed by Chanel Miller in her victim’s impact statement, read aloud during the case of People v. Turner. When anger functions in this way, I propose, it serves to moralize the emotion. In the second paper, titled “Feminism and Suspect Femininity,” I ask how feminists should feel towards women who conform to suspect norms of appearance, and of hyper-femininity in particular. I present a novel type of empathy – proleptic empathy – which avoids treating women as either pitiful victims or as accomplices deserving of harsh moral criticism. Proleptic empathy requires switching back and forth between two types of imaginings: on the one hand, simulating what it is like to be in the woman’s shoes on the assumption that her suspect behavior stems from her will. On the other, simulating what it is like to be in the woman’s shoes on the assumption that her suspect behavior stems from external cultural influences. In the third paper, “Transitional Moral Contexts,” I address how one should feel towards the perpetrators who figure in the cases that have gone by the language of ‘grey rape’ or ‘bad sex’. These cases are ones that are rife with disagreement, especially amongst members of the moral community, who even disagree over whether they ought to count as cases of ‘sexual assault’ or ‘rape’. My suggestion is that the reason we have such difficulty adjudicating individuals’ responsibility for cases of bad sex is because these are instances of transitional moral contexts where what it is to act morally is in the process of being actively negotiated by the moral community. With this analysis in place, I present reasons for and against deploying shame against those who falter in these cases.

description: We show that controllable inhomogeneous coupling between two-level systems and a common data bus provides a fast mechanism to produce multipartite entanglement. Our proposal combines resonant interactions and engineering of coupling strengths---between the qubits and the single mode---leading to well defined entangled states. Furthermore, we show that, if the two-level systems interact dispersively with the quantized mode, engineering of coupling strengths allows the controlled access of the symmetric Hilbert space of qubits.

description: Gene expression is vital to life, and changes in gene expression often underlie phenotypic evolution. However, our understanding of gene expression, especially in the context of evolution, is limited, and several fundamental questions remain unanswered. Using the budding yeast Saccharomyces cerevisiae as a model organism and combining experimental and computational approaches, I address four key questions about noises and errors of gene expression in my thesis. First, functionally related genes tend to be chromosomally clustered in eukaryotic genomes even after excluding tandem duplicates, but the biological significance of this widespread phenomenon is unclear. Using the GAL cluster in S. cerevisiae as a model, I demonstrated that synchronization of stochastic expressions drives the clustering of functionally related genes. This finding also elucidates how disorder in one biological phenomenon—gene expression noise—could prompt the emergence of order in another—genome organization. Second, gene expression suffers from a lack of perfect fidelity. The non-random structure of the standard genetic code (SGC) is commonly thought to reflect in part selection for robustness against protein synthesis error. I tested whether the SGC is robust against frameshift error and found that the observed frameshift-robustness of the SGC is a side effect of its mismatch-robustness. Third, a recent article reported that the SGC is optimized for nutrient conservation. I demonstrated that this finding was an artifact and that it is theoretically untenable and empirically unsupported. Forth, many eukaryotes show pervasive transcriptions of intergenic regions. But it is still debated whether the pervasive intergenic transcription has functional significance or simply reflects the promiscuity of RNA polymerases. I approach this question by comparing chance promoter activities with the expression levels of intergenic regions in S. cerevisiae. Overall, I found that a minute fraction of intergenic transcriptions may be functional. Together, these studies deepen our understanding of the molecular determinants, fitness effects, and evolutionary consequences of gene expression.

description: We extend the opinion formation approach to probe the world influence of economical organizations. Our opinion formation model mimics a battle between currencies within the international trade network. Based on the United Nations Comtrade database, we construct the world trade network for the years of the last decade from 2010 to 2020. We consider different core groups constituted by countries preferring to trade in a specific currency. We will consider principally two core groups, namely, 5 Anglo-Saxon countries which prefer to trade in US dollar and the 11 BRICS+ which prefer to trade in a hypothetical currency, hereafter called BRI, pegged to their economies. We determine the trade currency preference of the other countries via a Monte Carlo process depending on the direct transactions between the countries. The results obtained in the frame of this mathematical model show that starting from year 2014 the majority of the world countries would have preferred to trade in BRI than USD. The Monte Carlo process reaches a steady state with 3 distinct groups: two groups of countries preferring, whatever is the initial distribution of the trade currency preferences, to trade, one in BRI and the other in USD, and a third group of countries swinging as a whole between USD and BRI depending on the initial distribution of the trade currency preferences. We also analyze the battle between USD, EUR and BRI, and present the reduced Google matrix description of the trade relations between the Anglo-Saxon countries and the BRICS+.

description: Objectives: With increasing treatment choices for inflammatory bowel disease (IBD), patients’ preferences should be considered to limit non-adherence. We explored patients’ preferences for route, form and frequency of medication administration, and factors influencing these choices. Methods: Patients rated acceptability of different forms of medication on 10-point Likert scales and preferences for highest acceptable frequency. Results: Of 298 patients significantly more found tablets (91%) to be highly acceptable compared to granules (64%), infusions (33%) and subcutaneous injections (34%; p Conclusion: Most patients with IBD prefer tablets. Those patients who already experienced biological agents, had a high level of acceptance for subcutaneous and intravenous forms of medication.

description: It is well known that the long-term evolution of the photospheric magnetic field plays an important role in building up free energy to power solar eruptions. Observations, despite being controversial, have also revealed a rapid and permanent variation of the photospheric magnetic field in response to the coronal magnetic field restructuring during the eruption. The Helioseismic and Magnetic Imager instrument (HMI) on board the newly launched Solar Dynamics Observatory (SDO) produces seeing-free full-disk vector magnetograms at consistently high resolution and high cadence, which finally makes possible an unambiguous and comprehensive study of this important back-reaction process. In this study, we present a near disk-center, GOES -class X2.2 flare, which occurred in NOAA AR 11158 on 2011 February 15. Using the magnetic field measurements made by HMI, we obtained the first solid evidence of a rapid (in about 30 minutes) and irreversible enhancement in the horizontal magnetic field at the flaring magnetic polarity inversion line (PIL) by a magnitude of ~30%. It is also shown that the photospheric field becomes more sheared and more inclined. This field evolution is unequivocally associated with the flare occurrence in this sigmoidal active region, with the enhancement area located in between the two chromospheric flare ribbons and the initial conjugate hard X-ray footpoints. These results strongly corroborate our previous conjecture that the photospheric magnetic field near the PIL must become more horizontal after eruptions, which could be related to the newly formed low-lying fields resulted from the tether-cutting reconnection.

description: We discuss anomalous Higgs interactions in the scenario of gauge-Higgs unification. In the scenario Higgs originates from higher dimensional gauge field and has a physical meaning as AB phase or Wilson loop. As its inevitable consequence, physical observables are expected to be periodic in the Higgs field. In particular, the Yukawa coupling is expected to show some periodic and non-linear behavior as the function of the Higgs VEV. For a specific choice of the VEV, the Yukawa coupling of KK zero mode fermion even vanishes. On the other hand, the Yukawa coupling is originally provided by gauge interaction, which is linear in the Higgs field. We discuss how such two apparent contradiction about the non-linearity of the Yukawa coupling can be reconciled and at the same time how these two "pictures" give different predictions in the simplest framework of the scenario: SU(3) electroweak model in 5-dimensional flat space-time with orbifolding. The deviation of the Yukawa coupling from the standard model prediction is also calculated for arbitrary VEV. We study "$H$-parity", which guarantees the stability of the Higgs for a specific choice of the VEV. Also discussed is the Higgs interaction with $W^\pm$ and $Z^0$. It turns out that in our framework of flat space-time the interaction does not show deviation from the standard model prediction, except for the specific case of the VEV.

description: We have experimentally compared the critical current, dark count rate and photo-response of 100nm wide superconducting nanowires with different bend designs. Enhanced critical current for nanowires with optimally rounded bends, and thus with no current crowding, are observed. Furthermore, we find that the optimally designed bend significantly reduces the dark counts without compromising the photo-response of the device. The results can lead to major improvements in superconducting nanowire single photon detectors.

description: Two-dimensional shear wave elastography (2D-SWE), magnetic resonance elastography (MRE), aspartate transaminase-to-platelet ratio index (APRI), fibrosis index based on 4 factors (FIB-4), and King’s score have been proposed for diagnosing fibrosis. Literature databases were searched until October 1st, 2020. The summary area under the receiver operating characteristic curve (AUROC), the summary diagnostic odds ratios, and the summary sensitivities and specificities were used to assess the performance of these noninvasive methods for staging fibrosis. Our final data contained 72 studies. The prevalence of significant fibrosis, advanced fibrosis, and cirrhosis was 58.3%, 36.2%, and 20.5%, respectively, in chronic hepatitis B (CHB). For 2D-SWE and MRE, the summary AUROCs were 0.89 and 0.97, 0.95 and 0.97, and 0.94 and 0.97 for significant fibrosis, advanced fibrosis, and cirrhosis, respectively. The summary AUROCs using APRI and FIB-4 for detecting significant fibrosis, advanced fibrosis, and cirrhosis were 0.76 and 0.75, 0.74 and 0.77, and 0.77 and 0.82, respectively. The summary AUROCs of King’s score for detecting significant fibrosis and cirrhosis were 0.77 and 0.83, respectively. MRE and 2D-SWE may show the best diagnostic accuracy for predicting fibrosis in CHB. Among the three serum markers, King’s score may be more useful for diagnosing fibrosis.

description: Information Security has always been an important aspect of consideration in daily life communication and with the advent of COVID-19 and communication, including sensitive data like corporate files, personal data etc., increasingly moving online, it has become more important than ever to provide secure communication methods. One such method is using encryption and steganography. Encryption is the process of converting ordinary plaintext data into an alternative form that is unreadable by perpetrators without authorization. Furthermore, steganography is the practice of hiding a file, message, video, or image within another such file. In this paper, we introduce a web-application that will enable the user to encrypt the data in a file of his choice and then hide it within a picture or GIF. This will provide the layman an application that is easy to use to communicate securely, even without extensive technical knowledge. The encryption algorithm used will be the AES-256 algorithm and the steganographic algorithm will be Syndrome-Trellis Codes (STCs) for their high embedding efficiency. The results display that the system designed offers a significant security level.

description: We study boundary regional controllability problems for a class of semilinear fractional systems. Sufficient conditions for regional boundary controllability are proved by assuming that the associated linear system is approximately regionally boundary controllable. The main result is obtained by using fractional powers of an operator and the fixed point technique under the approximate controllability of the corresponding linear system in a suitable subregion of the space domain. An algorithm is also proposed and some numerical simulations performed to illustrate the effectiveness of the obtained theoretical results.

Analysis of photon-mediated entanglement between distinguishable matter qubits

description: We theoretically evaluate establishing remote entanglement between distinguishable matter qubits through interference and detection of two emitted photons. The fidelity of the entanglement operation is analyzed as a function of the temporal and frequency mode-matching between the photons emitted from each quantum memory. With a general analysis, we define limits on the absolute magnitudes of temporal and frequency mode-mismatches in order to maintain entanglement fidelities greater than 99% with two-photon detection efficiencies greater than 90%. We apply our analysis to several selected systems of quantum memories. Results indicate that high fidelities may be achieved in each system using current experimental techniques, while maintaining acceptable rates of entanglement. Thus, it might be possible to use two-photon-mediated entanglement operations between distinguishable quantum memories to establish a network for quantum communication and distributed quantum computation.

Life through a mathematical lens : building parental awareness of home numeracy practices through photography
Creators: name: Poirier, Natalie
Publisher: name: University of British Columbia

description: The home is a rich site for mathematics exploration, communication and discovery and parents play an invaluable role as their children’s first math teachers. However, literature suggests that parents do not often realize the mathematics in which their children engage at home (Beningno & Ellis, 2008; Tudge & Doucet, 2004; Warren & Young, 2002; Winter, Salway, Lee, & Huges, 2004). Pound (1999) highlights that unless children’s everyday activities are viewed with a mathematical lens the mathematics may go unnoticed. This study, grounded in the theoretical framework of numeracy as a social practice, examines the ways in which parental awareness of home numeracy experiences may be enhanced through photography and the photo interview. These methods have been frequently used in examining literacy practices and it seems reasonable that photographs may provide a language of inquiry for numeracy practices. Four parent dyads of prekindergarten to kindergarten aged children participated in two photo assignments where they were invited to capture events where their children were engaged in mathematics. Each assignment was followed up by a photo interview where parents were invited to discuss the mathematics being portrayed in photographs. An exit interview was conducted to allow parents to share what they learned from the experience. All parents pointed to an increased awareness of mathematics in the home. These results suggest that strategies such as used here foreground math for the parents and heighten their sensitivity to it.

description: Since the 1970s, video games have become a prominent form of entertainment media. Primarily developed in the United States initially, video games rapidly spread to other regions such as Japan and parts of Europe. An integral component of their worldwide spread was the process that allows them to be comprehensible across languages and cultures: localization. Localization is more than the translation of linguistic signs, it also accounts for cultural norms and expectations. This dissertation delves into the localization process from the perspective of three stakeholders: industry, players/fans, and press. Game publishers and developers adapt localization policies that guide the work of individual localizers and teams. Localizers work with development teams to modify game content for release in a target locale. Players interpret and respond to changes made during localization. In some cases, they act when a localization is denied for their region. Finally, press operates between industry and players to mediate understandings of individual games, genres, and entire regions as cultural producers. Ultimately, this dissertation concludes that localization is a liminal process in which multiple stakeholders interpret changes made to media artifacts. Localizers in the industry personalize games according to internal standards developed over decades. Fans and players can also act as localizers, and their ROM hacking work shows how programming and lingual translation are intricately connected in game localization. Game journalists mediate between industry and players, helping to contextualize games in larger social constructs such as genre.

description: We explain the multiple ring structure revealed in the disk around HL Tau as a  consequence of aggregate sintering.

We use a dust growth model to simulate  global dust evolution due to sintering, coagulation, fragmentation, and radial inward drift in a modeled HL Tau disk. Our best fitted model reproduces the positions of optically-thick bright rings with an accuracy of <30%.

description: The Blandford-Znajek process, one of the most promising model for powering the relativistic jets from black holes, was initially introduced as a mechanism in which the magnetic fields extract energy from a rotating black hole. We study the evolution of force-free electromagnetic fields on regular spacetimes with an ergosphere, which are generated by rapidly rotating stars. Our conclusive results confirm previous works, claiming that the Blandford-Znajek mechanism is not directly related to the horizon of the black hole. We also show that the radiated energy depends exponentially on the compactness of the star.

description: The self-consistent Hartree-Fock-Bogoliubov problem in large boxes can be solved accurately in the coordinate space with the recently developed solvers HFB-AX (2D) and MADNESS-HFB (3D). This is essential for the description of superfluid Fermi systems with complicated topologies and significant spatial extend, such as fissioning nuclei, weakly-bound nuclei, nuclear matter in the neutron star rust, and ultracold Fermi atoms in elongated traps. The HFB-AX solver based on B-spline techniques uses a hybrid MPI and OpenMP programming model for parallel computation for distributed parallel computation, within a node multi-threaded LAPACK and BLAS libraries are used to further enable parallel calculations of large eigensystems. The MADNESS-HFB solver uses a novel multi-resolution analysis based adaptive pseudo-spectral techniques to enable fully parallel 3D calculations of very large systems. In this work we present benchmark results for HFB-AX and MADNESS-HFB on ultracold trapped fermions.
