Publisher: name: The University of British Columbia
Year: 2023

description: In August 2022, a roost of endangered little brown bats (Myotis lucifugus, hereafter M. lucifugus) was found on UBC Campus, inside the Auditorium Annex Offices. Concerns have been raised by building residents and UBC Facilities about bat activity and bat droppings near the roost. To alleviate these concerns and provide an alternative habitat for these bats, our ENVR 400 project team partnered with UBC SEEDS to help relocate the bats. M. lucifugus has been an endangered species since 2014 due to a fungal disease known as White Nose Syndrome, which has caused widespread mortality. This is not well known among the public, and there are few groups advocating for the conservation of these bats, despite the fact that M. lucifugus prey on insects that harm human health and agricultural productivity, providing desirable ecosystem services in urban environments. Important factors when determining suitable habitat for M. lucifugus include temperature, protection from predators, proximity to water bodies, and density of vegetation. Bat boxes can be a suitable substitute to roosting sites if they are located within suitable habitat. Our main research objectives were as follows: 1) identify a suitable location for a bat box near the current roost, 2) purchase a bat box that meets the roost’s habitat needs, and 3) recommend procedures for protecting the roost and addressing gaps in UBC wildlife conservation policy. To identify suitable habitat, our team first conducted a GIS analysis. This allowed us to weigh different factors relevant to bat habitat suitability, including proximity to water bodies and buildings, density of trees, and density of soft vegetation. Following this, we scouted suitable sites in-person and consulted with various bat experts and UBC staff to understand the benefits and drawbacks of each installation location (Figure 1). One Dual Quad Chamber bat box was obtained after consulting with bat experts to ensure the box met the roost’s needs. Finally, the installation process was developed in collaboration with external contractors and UBC Building Operations. The installation location we selected is in a field approximately 120m away from the current roost (Figure 2). Due to the close proximity to the current roost, our group felt this location provided the best opportunity for a successful relocation.

Subjects: subject: Cryptography and Security (cs.CR)

description: Attacks based on side-channel analysis (SCA) pose a severe security threat to modern computing platforms, further exacerbated on IoT devices by their pervasiveness and handling of private and critical data. Designing SCA-resistant computing platforms requires a significant additional effort in the early stages of the IoT devices' life cycle, which is severely constrained by strict time-to-market deadlines and tight budgets. This manuscript introduces a hardware-software framework meant for SCA research on FPGA targets. It delivers an IoT-class system-on-chip (SoC) that includes a RISC-V CPU, provides observability and controllability through an ad-hoc debug infrastructure to facilitate SCA attacks and evaluate the platform's security, and streamlines the deployment of SCA countermeasures through dedicated hardware and software features such as a DFS actuator and FreeRTOS support. The open-source release of the framework includes the SoC, the scripts to configure the computing platform, compile a target application, and assess the SCA security, as well as a suite of state-of-the-art attacks and countermeasures. The goal is to foster its adoption and novel developments in the field, empowering designers and researchers to focus on studying SCA countermeasures and Attacks while relying on a sound and stable hardware-software platform as the foundation for their research.

description: This study utilized one on one semi-structured interviews with twenty-four participants to investigate how individuals experience dating and navigate uncertainty during the COVID-19 pandemic. Uncertainty Reduction theory was used as the theoretical framework to inform this study. A thematic analysis of the interviews revealed shifts in how dating was experienced as well how the conceptualizations of dating changed during the COVID-19 pandemic. Specifically, there was a new uncertainty in dating that the COVID-19 pandemic brought: the risk of contracting COVID-19. This risk led to three strategies to navigate and reduce the uncertainty, which were 1) Passive Strategies, 2) Interactive Strategies, and 3) Extractive Strategies. Additionally, two dialectical tensions were found, which were 1) A dialectical tension between fatigue at navigating this new normal and adaptation, and 2) A dialectical tension between frustration at this new normal, yet also recognition of the positives it has brought. These findings extend and complicate the literature on uncertainty reduction theory, and conceptualizations of dating.
The Narcotic Addiction Foundation of British Columbia and the Emergence of a Healthcare System for Illicit Drug Use
Creators: name: Andre-Peirano, Nathaniel Mark
Publisher: name: The University of British Columbia
Year: 2023

description: This thesis examines the history of the NAF in three comprehensive chapters. In chapter one, the formation of the NAF is analyzed to reveal how a contestation of ideas resulted in the first medical clinic for heroin addiction treatment in British Columbia. Chapter two chronologically follows and discusses two treatment methods that underpin the NAF's ideological development as an addiction treatment provider. For example, chapter two shows how the NAF developed ideas surrounding the "Prolonged Withdrawal" method which resulted in an ideological return to the prison as treatment model in the context of addiction. Chapter three brings new light to the NAF's final years to reveal how the NAF was the foundation of British Columbia's addiction treatment infrastructure and was influential, if not largely responsible, for British Columbia's Heroin Treatment Act of 1978. Ultimately, this thesis provides a comprehensive and systematic analysis of the NAF from inception to cessation to argue that the initial NAF values of voluntary addiction treatment and rehabilitation were superseded by the desire to compel all illicit drug users into treatment for the sake of preserving individual and national health.

A minimal model for multigroup adaptive SIS epidemics

description: We propose a generalization of the adaptive N-Intertwined Mean-Field Approximation (aNIMFA) model studied in Achterberg and Sensi (2023) to a heterogeneous network of communities. In particular, the multigroup aNIMFA model describes the impact of both local and global disease awareness on the spread of a disease in a network. We obtain results on existence and stability of the equilibria of the system, in terms of the basic reproduction number $R_0$. Assuming individuals have no reason to decrease their contacts in the absence of disease, we show that the basic reproduction number $R_0$ is equivalent to the basic reproduction number of the NIMFA model on static networks. Based on numerical simulations, we demonstrate that with just two communities periodic behaviour can occur, which contrasts the case with only a single community, in which periodicity was ruled out analytically. We also find that breaking connections between communities is more fruitful compared to breaking connections within communities to reduce the disease outbreak on dense networks, but both strategies are viable to networks with fewer links. Finally, we emphasize that our method of modelling adaptivity is not limited to SIS models, but has huge potential to be applied in other compartmental models in epidemiology.

title: Probiotics Attenuate Cocaine-seeking Behavior in Adult but not Adolescent Male Rats
Creators: name: Mesape, Kevin
Publisher: name: Georgia State University
Year: 2021

description: Perturbations to the gut microbiome may boost the use of addictive substances such as cocaine. In animals, antibiotic-induced gut microbiome depletion heightens cocaine-seeking, although adolescent rats appear less sensitive than adults to these perturbations. The purpose of this study was to use adolescent vs. adult male Wistar rats to test two hypotheses: 1) probiotics will reduce cocaine-seeking that has been heightened by antibiotic treatment; and 2) probiotics administered throughout behavioral testing will reduce cocaine-taking and/or -seeking. Rats were catheterized and self-administered cocaine (0.36mg/kg i.v.), then tested for extinction and reinstatement of cocaine-seeking after abstinence. Some rats received antibiotics during self-administration followed by probiotics during abstinence, while others received probiotics throughout testing. Probiotics during abstinence attenuated antibiotic-heightened cocaine-seeking in adults but did not decrease adolescent responses. Prophylactic probiotics did not attenuate cocaine behaviors significantly. Probiotics may be useful in addiction treatment, but these results do not support their use in prevention.

description: Large Vision-Language Models (LVLMs) have achieved significant success in recent years, and they have been extended to the medical domain. Although demonstrating satisfactory performance on medical Visual Question Answering (VQA) tasks, Medical LVLMs (MLVLMs) suffer from the hallucination problem, which makes them fail to diagnose complex pathologies. Moreover, they readily fail to learn minority pathologies due to imbalanced training data. We propose two prompting strategies for MLVLMs that reduce hallucination and improve VQA performance. In the first strategy, we provide a detailed explanation of the queried pathology. In the second strategy, we fine-tune a cheap, weak learner to achieve high performance on a specific metric, and textually provide its judgment to the MLVLM. Tested on the MIMIC-CXR-JPG and Chexpert datasets, our methods significantly improve the diagnostic F1 score, with the highest increase being 0.27. We also demonstrate that our prompting strategies can be extended to general LVLM domains. Based on POPE metrics, it effectively suppresses the false negative predictions of existing LVLMs and improves Recall by approximately 0.07.

Une étude quantitative a été menée avec 240 réponses valides et les données ont été analysées à l'aide du logiciel SPSS. Les résultats indiquent que la crédibilité de l'influenceur renforce de manière significative la confiance du public dans les informations relatives à la qualité de l'eau, ce qui indique que les influenceurs crédibles ont un impact plus important sur la perception et l'engagement du public. Le contenu émotionnel s'est avéré plus efficace que le contenu factuel ou visuel pour sensibiliser et encourager l'action, ce qui souligne l'importance de l'attrait émotionnel dans la communication environnementale. Cependant, l'étude n'a pas mis en évidence de lien significatif entre l'âge et la probabilité de s'engager dans un contenu d'influence sur la qualité de l'eau, ce qui suggère que les campagnes menées par des influenceurs peuvent cibler efficacement des groupes démographiques divers. Les résultats de cette étude offrent des perspectives intéressantes pour optimiser les stratégies de communication environnementale menées par les influenceurs et renforcer l'engagement du public en faveur des efforts de conservation de l'eau.

description: In this preprint we analyzed the exclusive photoproduction of $η_{c}γ$ pairs in the collinear factorization framework and evaluated its cross-section in leading order in the strong coupling $α_{s}$. We found that this process is mostly sensitive to the behavior of the unpolarized gluon GPD $H_{g}$ in the Efremov-Radyushkin-Brodsky-Lepage kinematics. We estimated numerically the cross-section and the expected counting rates in the kinematics of middle-energy photoproduction experiments which can be realized at the future Electron-Ion Collider and in the kinematics of ultraperipheral collisions at LHC. We found that the cross-section is sufficiently large for dedicated experimental study.

South Asian Mental Health Concerns in Canada due to the COVID-19 Pandemic

description: The COVID-19 pandemic has devastated families around the world; but such effects have disproportionately hit certain populations more than others. Internationally, this in differences can be seen in infection/hospitalization/fatality rates across the world. Nationally, this disparity across various social lines, most prominently based on ethnicity. As COVID-19 swept across Canada, each province and territory had to figure out how to best manage this virus, often shutting down who sectors of economic activity while relying on those performing essential services to keep the world running. Unfortunately, zooming into Greater Vancouver, many essential services are visibly and disproportionately reliant on racialized folks, whether this include grocery store workers, truckers, healthcare providers, laundry service providers, meat works, or many others. This places racialized folks at a much greater risk of becoming infected with, or dying from, COVID-19 – including South Asian diaspora. Read Harleen’s impassioned letter to her Member of Parliament, Hon. Carla Qualtrough, as she dissects the racialized impact of the pandemic, and what needs to be done to help the South Asian diasporic community. So what can be done beyond the generic colour-blind health interventions that are already available?

description: The recent availability of quantum annealers as cloud-based services has enabled new ways to handle machine learning problems, and several relevant algorithms have been adapted to run on these devices. In a recent work, linear regression was formulated as a quadratic binary optimization problem that can be solved via quantum annealing. Although this approach promises a computational time advantage for large datasets, the quality of the solution is limited by the necessary use of a precision vector, used to approximate the real-numbered regression coefficients in the quantum formulation. In this work, we focus on the practical challenge of improving the precision vector encoding: instead of setting an array of generic values equal for all coefficients, we allow each one to be expressed by its specific precision, which is tuned with a simple adaptive algorithm. This approach is evaluated on synthetic datasets of increasing size, and linear regression is solved using the D-Wave Advantage quantum annealer, as well as classical solvers. To the best of our knowledge, this is the largest dataset ever evaluated for linear regression on a quantum annealer. The results show that our formulation is able to deliver improved solution quality in all instances, and could better exploit the potential of current quantum devices.

description: We have studied the origin of zero volume expansion below the Curie temperature (Tc), variable range hopping (VRH) behaviour using structural, magnetic, transport and thermal studies on the oxygen deficient double perovskite NdBaCo$_2$O$_{5+δ}$ ($δ\sim 0.65$). The valence state of Co ions and the possible properties exhibited by such compound were studied using electronic structure calculations for $δ= 0.75$. Careful investigation of structure shows that the compound stabilizes in tetragonal structure (P4/mmm) having $2a_p \times 2a_p \times 2a_p$ (222) superstructure, where $a_p$ is the cubic perovskite lattice parameter. The compound exhibits a minimum in resistivity, ferromagnetic and ferrimagnetic transitions around 375 K, 120 K ($T_c$) and 60 K, respectively with signature of Griffiths phase above $T_c$. Our detailed structural analysis suggests signature of the onset of the above magnetic transitions at temperatures well above its stabilisation at long range level thereby leading to VRH behaviour. The observed zero thermal expansion in volume below Tc appears to be due to competing magnetic interactions within and between the magnetic sublattices. Our electronic structure calculations show (a) the importance of electron-electron correlation in Nd $4f$ and Co $3d$ states (b) Co ions stabilize in intermediate spin (IS) state, having oxidation state less than +3 (c) half metallicity. Our results show the possibility of coupling between magnetism and ferroelectricity. We believe that our results especially on the valence state of the Co ion, zero thermal expansion in volume, short range magnetic orderings and the connection between different degrees of freedom will be helpful in clearing the ambiguities existing in literature on the nature of magnetism and thereby aiding in designing new functionalities.

description: In this work we introduce and characterize a broad class of quantum operations with a unique fixed point, termed quantum ergodic channels. We derive Lindblad-type master equations for these channels in arbitrary finite dimensions and analyze their non-Markovian dynamics using established measures. When the fixed point is a passive state, the channels exhibit ergotropy dynamics with notable thermodynamic implications. Specifically, under Markovian processes, ergotropy, a measure of the extractable work from a system under unitary evolution monotonically decreases. However, in non-Markovian dynamics, ergotropy fluctuates, leading to a backflow effect that highlights memory-induced resource recovery. Our findings suggest that this ergotropy backflow could serve as an operationally meaningful indicator of non-Markovianity, offering new perspectives on the interplay between memory effects and thermodynamic behavior in open quantum systems. This study enhances the theoretical framework for understanding energy dynamics under ergodic channels and highlights new avenues for exploring the implications of memory effects in quantum batteries.

description: The path-integral approach to topological quantum error correction provides a unified way to construct and analyze fault-tolerant circuits in spacetime. In this work, we demonstrate its utility and versatility at hand of a simple example: We construct a new fault-tolerant circuit for the toric-code phase by traversing its path integral on a $(x,y,z)$ cubic lattice in the $x+y$ direction. The circuit acts on qubits on a square lattice, and alternates between horizontal nearest-neighbor $CX$ gates and vertical nearest-neighbor $ZZ$ and $XX$ measurements. We show how to incorporate boundaries and corners into the fault-tolerant circuit and how to perform topologically protected logic gates. As a specific example, we consider performing a fault-tolerant logical $ZZ$ measurement via lattice surgery of two spatial rectangular blocks of our fault-tolerant circuit.

En reconnaissant l'importance cruciale de l'éducation dans des contextes nomades et conflictuels, cette recherche s'inscrit dans un cadre d'étude qui cherche à évaluer les solutions éducatives adaptatives pour des communautés en situation de mobilité et de crise.

Méthodologiquement, l'étude combine des approches qualitatives et quantitatives, incluant la recherche documentaire et des enquêtes sur le terrain, pour recueillir des données sur les effectifs scolaires, les perceptions des communautés, et l'efficacité opérationnelle des écoles mobiles. Les résultats révèlent une contribution positive de ces écoles à l'amélioration de l'accès à l'éducation primaire, malgré des fluctuations dues au contexte sécuritaire instable.

L'implication pratique majeure de cette étude suggère la nécessité d'un soutien accru des écoles mobiles par les décideurs et praticiens de l'éducation, notamment par la dotation de ressources adéquates, la formation du personnel enseignant, et l'amélioration des conditions de sécurité. En outre, la recherche souligne la pertinence des écoles mobiles dans la réduction des inégalités éducatives et la promotion d'une éducation inclusive et résiliente.

Cette étude contribue significativement à la littérature existante sur l'éducation en milieu nomade et conflictuel en validant empiriquement l'efficacité des écoles mobiles dans le CAP de Mopti. Elle offre des perspectives enrichissantes pour la conceptualisation de politiques éducatives adaptatives et inclusives, capable de répondre aux besoins des communautés nomades dans des contextes similaires.

description: We analyze the analytic structure of correlators in the field theory dual to the quantum Bañados-Teitelboim-Zanelli (qBTZ) black hole, a braneworld model incorporating exact backreaction from quantum conformal matter. We first compute the quasi-normal mode (QNM) spectrum of operators with dimension $Δ$ and spin $s=0,\pm 1/2$. The leading QNMs and their overtones display qualitatively different behavior depending on the branch of qBTZ solution, which corresponds to distinct CFT states: branch 1 is a conical singularity dressed with a horizon while branch 2 is a quantum-corrected BTZ black hole. Consequently, the relaxation of probe matter effectively differentiates the CFT states and identifies the corresponding bulk descriptions. We then turn to pole-skipping locations where Green's functions are not unique. At these points, frequency is proportional to temperature, but momentum exhibits complex temperature dependence due to quantum effects. Under the assumption that the pole-skipping point closest to the origin reflects quantum chaos, we infer the likely behavior of the quantum Lyapunov exponent and butterfly velocity in the dual theory. Finally, we examine pole collisions in complex momentum space, showing that quantum corrections imprint a unique signature on the analytic structure of the poles in retarded Green's functions, resulting in level-crossing phenomena that differ notably from the level-touching phenomena in the uncorrected BTZ geometry.

description: Unsupervised learning has become an essential building block of AI systems. The representations it produces, e.g. in foundation models, are critical to a wide variety of downstream applications. It is therefore important to carefully examine unsupervised models to ensure not only that they produce accurate predictions, but also that these predictions are not "right for the wrong reasons", the so-called Clever Hans (CH) effect. Using specially developed Explainable AI techniques, we show for the first time that CH effects are widespread in unsupervised learning. Our empirical findings are enriched by theoretical insights, which interestingly point to inductive biases in the unsupervised learning machine as a primary source of CH effects. Overall, our work sheds light on unexplored risks associated with practical applications of unsupervised learning and suggests ways to make unsupervised learning more robust.

Constructions for Nonadaptive Tropical Group Testing

description: PCR testing is an invaluable diagnostic tool that has most recently seen widespread use during the COVID-19 pandemic. A recent work by Wang, Gabrys and Vardy proposed tropical codes as a model for group PCR testing. For a known but arbitrary number of infected persons, a sufficient condition on the underlying block design of a zero-error tropical code, called double disjunction, is proposed. Despite this, the parameters for which the construction of doubly disjunct block designs is known to exist are very limited. In this thesis, we define probabilistic tropical codes and consider random block designs that are doubly disjunct with high probability. We also provide a deterministic construction for a doubly disjunct block design given a disjunct block design. We show that for certain choices of parameters, our probabilistic construction has vanishing error. Our constructions, combined with existing methods, give us three different ways to construct tropical codes. We compare the number of tests required by each, and bounds on the error.

description: Актуальность обусловлена необходимостью разработки эффективных инструментов для управления кредитными ресурсами, ограниченными структурными особенностями отечественной экономики. Предложен комплексный методический подход к моделированию предикторов прибыли кредитных организаций. Для эмпирической оценки моделей прибыли использована гребневая регрессия и регрессия на главных компонентах. Для выявления и измерения драйверов потребительского кредитования представлены модели анализа панельных данных, качество моделей проверено с помощью теста Фишера и теста Хаусмана. Анализ регрессоров ипотечного кредита дополнен коррекцией на гетероскедастичность. Результаты анализа, выполненного с применением пакета программ Gretl, свидетельствуют о том, что методический подход применим в кредитных организациях для управления кредитным портфелем с целью увеличения прибыли. В дальнейших исследованиях представляет интерес проверка гипотез о линейных ограничениях в моделях прибыли, измерение гетерогенности причинно-следственных связей в разрезе сроков и размеров потребительских кредитов, прогнозирование решения заимодателя о выдаче кредита, измерение прогностических факторов ипотечного кредита.
description: The relevance of the research stems from the need to develop effective tools for credit management that is restrained by structural features of the national econ-omy. A comprehensive methodological approach to modeling credit predictors of credit organizations is offered. For empirical estimator of profit model, ridge regression and principal components regression profit is used. The paper presents panel data analysis mod-el to identify and measure consumer crediting drivers, the quality of the models is tested using Fisher's test and Hausman test. Analysis of the mortgage regres-sors is adjusted for heteroskedasticity. Results of the analysis performed using the Gretl software package indicate that the methodological approach is applica-ble to credit institutions to manage the credit portfolio in order to increase profits. In future studies, it is of in-terest to test hypotheses about the linear constraints of profit models, measurement of heterogeneity of causal relations in the context of the period and size of consumer loans, forecasting loan approval by lender, measurement of mortgage prognostic factors.

description: Soft robots can exhibit better performance in specific tasks compared to conventional robots, particularly in healthcare-related tasks. However, the field of soft robotics is still young, and designing them often involves mimicking natural organisms or relying heavily on human experts' creativity. A formal automated design process is required. We propose the use of neuroevolution-based algorithms to automatically design initial sketches of soft actuators that can enable the movement of future medical devices, such as drug-delivering catheters. The actuator morphologies discovered by algorithms like Age-Fitness Pareto Optimization, NeuroEvolution of Augmenting Topologies (NEAT), and Hypercube-based NEAT (HyperNEAT) were compared based on the maximum displacement reached and their robustness against various control methods. Analyzing the results granted the insight that neuroevolution-based algorithms produce better-performing and more robust actuators under different control methods. Moreover, the best-performing morphologies were discovered by the NEAT algorithm. As a future work aspect, we propose using the morphologies discovered here as test beds to optimize specialized controllers, enabling more effective functionality towards the desired deflections of the suggested soft catheters.
