description: We have investigated spin-related effects on the electronic transport in a single antidot system in the vicinity of the $ν= 2$ quantum Hall state where two edge states with different spins of the lowest Landau level are formed around the antidot. The conductance exhibits the paired $h/2e$ Aharonov-Bohm (AB) oscillations. Using a tilted magnetic field technique, we have observed the evolution of the oscillations with the total magnetic field and a concomitant change in the source-drain bias dependence of the differential conductance. From the observation, we extract the effect of the Zeeman energy on the AB oscillations.

description: In the present contribution, a novel cyclobutane-derived thiazole–thiourea hybrid 1-(4-(3-methyl-3-phenylcyclobutyl)thiazol-2-yl)−3-(p-tolyl)thiourea (1), which was readily fabricated from addition of p-isothiocyanatotoluene to 4-(3-methyl-3-phenylcyclobutyl)thiazol-2-amine, is reported. The formation of 1 was firmly confirmed by the means of elemental analysis, and IR and 1H NMR spectroscopy. Theoretical DFT-based computations were additionally applied to reveal the structure and electronic features of the title compound. The chemical activity of 1 was estimated by the reactivity descriptors and MEP surface. ADMET properties of the reported compound were predicted in silico using online services. Potential inhibition of a series of the SARS-CoV-2 and tick-borne encephalitis proteins by 1 was studied using molecular docking, which, in turn, allowed to reveal the ligand efficiency scores for the resulting protein–1 complexes. It was established that 1 exhibits the best inhibition activity against Nonstructural protein 14 (N7-MTase) and tick-borne encephalitis virus (TBEV) glycoprotein amongst the studied SARS-CoV-2 and TBE proteins, respectively.

description: A greener and direct approach to the efficient synthesis of fused heterocyclic ring system benzo[4,5]imidazo[2,1-b]thiazoles via C–N and C–S bond formation in catalyst-free conditions has been reported using 2,2,2-trifluoroethanol (TFE) as a reaction medium at room temperature. The salient features of this approach include an elementary and clean reaction protocol to afford the desired product in higher yields in less reaction time with sufficient purity. This prominent moiety is frequently found in many natural bioactive occurring compounds and shows potential in synthesizing diverse biologically active compounds due to their therapeutic values. The synthesis of benzo[4,5]imidazo[2,1-b]thiazoles was confirmed by spectral analysis and also by DFT studies.

description: We present a multi-wavelength observation of a solar flare occurring on 2006 December 13 with Hinode, RHESSI, and the Nobeyama Radio Observatory, to study the electron acceleration site and mechanism. The Solar Optical Telescope (SOT) on board Hinode observed elongated flare ribbons, and RHESSI observed double-footpoint hard X-ray (HXR) sources appearing in part of the ribbons. A photospheric vector magnetogram obtained from SOT reveals that the HXR sources are located at the region where horizontal magnetic fields change the direction. The region is interpreted as the footpoint of magnetic separatrix. Microwave images taken with the Nobeyama Radioheliograph show a loop structure connecting the HXR sources. The brighter parts of the microwave intensity are located between the top and footpoints of the loop. We consider these observations as an evidence of the electron acceleration near the magnetic separatrix and injection parallel to the field line.

description: The aim of this study is to predict the efficiency of oxidative desulfurization method (in a gas–liquid oxidation system) for gas condensate using artificial intelligence (AI) systems such as Fuzzy Inference System, Adaptive Neuro-Fuzzy Inference System (ANFIS), Genetic Algorithm (GA)-Fuzzy, and GA-ANFIS. The method utilizes mixtures of H2SO4, HNO3, and NO2 as oxidant agents in various amounts. The optimal parameters of the proposed models were determined using GA, and statistical parameters such as mean absolute error, average relative deviation, and correlation coefficient were used to compare the models. The correlation coefficients for Fuzzy, ANFIS, GA-Fuzzy, and GA-ANFIS models were found to be 0.5899, 0.7831, 0.9693, and 0.9687, respectively. The results indicated that ANFIS-GA and Fuzzy-GA models can effectively predict the desulfurization efficiency of the novel technique. Furthermore, the use of GA improved the performance of the Fuzzy and ANFIS models and enhanced their prediction accuracy. Overall, this study demonstrates the potential of AI systems in predicting the efficiency of novel chemical methods for industrial applications.

description: We consider labelings of a finite regular tree by a finite alphabet subject to restrictions specified by a nonnegative transition matrix, propose an algorithm for determining whether the set of possible configurations on the last row of the tree is independent of the symbol at the root, and prove that the algorithm succeeds in a bounded number of steps, provided that the dimension of the tree is greater than or equal to the maximum row sum of the transition matrix. (The question was motivated by calculation of topological pressure on trees and is an extension of the idea of primitivity for nonnegative matrices.)

description: Aldous' spectral gap conjecture asserts that on any graph the random walk process and the random transposition (or interchange) process have the same spectral gap. We prove the conjecture using a recursive strategy. The approach is a natural extension of the method already used to prove the validity of the conjecture on trees. The novelty is an idea based on electric network reduction, which reduces the problem to the proof of an explicit inequality for a random transposition operator involving both positive and negative rates. The proof of the latter inequality uses suitable coset decompositions of the associated matrices on permutations.

Distributed Principal Component Analysis for Wireless Sensor Networks

description: The Principal Component Analysis (PCA) is a data dimensionality reduction technique well-suited for processing data from sensor networks. It can be applied to tasks like compression, event detection, and event recognition. This technique is based on a linear transform where the sensor measurements are projected on a set of principal components. When sensor measurements are correlated, a small set of principal components can explain most of the measurements variability. This allows to significantly decrease the amount of radio communication and of energy consumption. In this paper, we show that the power iteration method can be distributed in a sensor network in order to compute an approximation of the principal components. The proposed implementation relies on an aggregation service, which has recently been shown to provide a suitable framework for distributing the computation of a linear transform within a sensor network. We also extend this previous work by providing a detailed analysis of the computational, memory, and communication costs involved. A compression experiment involving real data validates the algorithm and illustrates the tradeoffs between accuracy and communication costs.

description: Grid environment is a service oriented infrastructure in which many heterogeneous resources participate to provide the high performance computation. One of the bug issues in the grid environment is the vagueness and uncertainty between advertised resources and requested resources. Furthermore, in an environment such as grid dynamicity is considered as a crucial issue which must be dealt with. Classical rough set have been used to deal with the uncertainty and vagueness. But it can just be used on the static systems and can not support dynamicity in a system. In this work we propose a solution, called Dynamic Rough Set Resource Discovery (DRSRD), for dealing with cases of vagueness and uncertainty problems based on Dynamic rough set theory which considers dynamic features in this environment. In this way, requested resource properties have a weight as priority according to which resource matchmaking and ranking process is done. We also report the result of the solution obtained from the simulation in GridSim simulator. The comparison has been made between DRSRD, classical rough set theory based algorithm, and UDDI and OWL S combined algorithm. DRSRD shows much better precision for the cases with vagueness and uncertainty in a dynamic system such as the grid rather than the classical rough set theory based algorithm, and UDDI and OWL S combined algorithm.

Relational performance pedagogy : Decroux and Grotowski based innovations in Western Canada
Creators: name: Fogal, Claire Arianne
Publisher: name: University of British Columbia
Year: 2024

description: This dissertation documents and analyzes the previously undocumented pedagogical practices and innovations of four North American senior teachers who together have taught over 2500 students in Western Canada over the past four decades: Dean Fogal, Linda Putnam, Kathleen Weiss, and David MacMurray Smith. In different ways, each has extended the physical theatre lineages of either French Corporeal Mime Etienne Decroux or Polish Director Jerzy Grotowski, or both. Focused on the complex issue of transmission of embodied practices, I examine the changes that Fogal and Putnam made in their own performance pedagogies after having trained directly with Decroux (Fogal) and Grotowski (Putnam). I also explore the pedagogical practices of Weiss and MacMurray Smith who both studied with Putnam, while MacMurray Smith also trained in Corporeal Mime with Jean Asselin and Denise Boulanger (who studied with Decroux for five years). This project has involved archival research and literature review, including study of Indigenous models of relational research which have influenced my approach. Following UBC protocols for ethical research, the thesis also builds from personal interviews, group discussions, arts-based qualitative research, and participatory collaborative research including filmed demonstrations and teaching sessions. Through the guidance and support of the UBC Graduate and Postdoctoral Studies Public Scholars Initiative, this thesis includes two documentary films crafted from this footage. The introductory film Swimming Back to Source provides context for understanding my connection to Decroux’s work through my father Dean Fogal. Within Chapter 3, the film Relational Performance Pedagogy documents and shares Fogal, Putnam, Weiss, and MacMurray Smith’s respective performance pedagogies, practices, and perspectives. These four teachers have developed what I term “relational performance pedagogy” as a result of principles they learned from Decroux and Grotowski as well as their own innovations from within the laboratory theatre tradition. Techniques developed by these teachers promote the autonomy and wellbeing of the actor by cultivating a capacity for what I define as portable “grounded belonging” rooted in both the training/performance space itself and in the surrounding ensemble (fellow actors and audience members).

description: A branch and bound algorithm is developed for global optimization. Branching in the algorithm is accomplished by subdividing the feasible set using ellipses. Lower bounds are obtained by replacing the concave part of the objective function by an affine underestimate. A ball approximation algorithm, obtained by generalizing of a scheme of Lin and Han, is used to solve the convex relaxation of the original problem. The ball approximation algorithm is compared to SEDUMI as well as to gradient projection algorithms using randomly generated test problems with a quadratic objective and ellipsoidal constraints.

description: Four organoruthenium(II) arene dithiocarbamate complexes: RuCl(piperidine dithiocarbamate)(p-cymene), C1; RuCl(1-phenylpiperazine dithiocarbamate)(p-cymene), C2, RuCl(ethylphenyl dithiocarbamate)(p-cymene), C3; RuCl(4-benzylpiperidine dithiocarbamate)(p-cymene), C4 were synthesized and characterized by elemental analysis, UV-Vis, FTIR, NMR and mass spectroscopic techniques. Spectroscopic data indicate that the complexes are four coordinate tetrahedral geometry consisting of one dithiocarbamato anion, p-cymene and a chlorido ligand around the ruthenium(II) ion. The dithiocarbamato anions coordinate the ruthenium(II) ions isobidentately. The cytotoxic effects of the compounds were assessed against human cervical cancer (HeLa) and human lung fibroblast (MRC5-SV2) cell lines using the 3-(4,5-dimethylthiazol-2-yl)−2,5-diphenyl tetrazolium bromide (MTT) assay. Only two compounds, C1 and C3 showed potent cytotoxicity after 48 h treatment. C1 was the most potent, with IC50 values of 6.7 ± 2.3 µM and 8.1 ± 0.8 µM against the HeLa and MRC5-SV2 cells, respectively, while C3 had IC50 values of 11.5 ± 3.1 µM and 10.3 ± 1.3 µM, respectively. Remarkably, compared to cisplatin (used as the reference anticancer drug), C1 was twice more potent against HeLa cells and more than five times more potent against MRC5-SV2 cells, while C3 was nearly equipotent with cisplatin against HeLa cells but five times more potent against MRC5-SV2 cells. These two compounds exhibited good potential as anticancer agents, thus warranting further studies.

description: We consider quantum transport and tunneling magnetoresistance (TMR) through an interacting quantum dot in the Coulomb blockade regime, attached to ferromagnetic leads. We show that there exist two kinds of anomalies of TMR, which have different origin. One type, associated with TMR sign change and appearing at conductance resonances, is of single particle origin. The second type, inducing a pronounced increase of TMR value far beyond 100%, is caused by electron correlations. It is manifested in-between Coulomb blockade conductance peaks. Both types of anomalies are discussed for zero and finite bias and their robustness to the temperature increase is also demonstrated. The results are presented in the context of recent experiments on semiconductor quantum dots in which similar features of TMR have been observed.

description: Tetravex is a widely played one person computer game in which you are given $n^2$ unit tiles, each edge of which is labelled with a number. The objective is to place each tile within a $n$ by $n$ square such that all neighbouring edges are labelled with an identical number. Unfortunately, playing Tetravex is computationally hard. More precisely, we prove that deciding if there is a tiling of the Tetravex board is NP-complete. Deciding where to place the tiles is therefore NP-hard. This may help to explain why Tetravex is a good puzzle. This result compliments a number of similar results for one person games involving tiling. For example, NP-completeness results have been shown for: the offline version of Tetris, KPlumber (which involves rotating tiles containing drawings of pipes to make a connected network), and shortest sliding puzzle problems. It raises a number of open questions. For example, is the infinite version Turing-complete? How do we generate Tetravex problems which are truly puzzling as random NP-complete problems are often surprising easy to solve? Can we observe phase transition behaviour? What about the complexity of the problem when it is guaranteed to have an unique solution? How do we generate puzzles with unique solutions?

description: Sulphur-containing compounds are highly significant as they can possess a variety of biological activities that make them useful for pharmacological purposes and for the mechanism by which drugs such as antibiotics bind to and disrupt bacterial cell walls. In this study, novel thioalkyl substituted-1,3,4 oxadiazole-bearing sulfonamide compounds have been successfully synthesized and characterized by 1HNMR, 13CNMR, IR and elemental analysis. The effects of different thioalkyl groups on the 1,3,4 oxadiazole group, the IC50 value for Bovine Carbonic Anhydrase (BCA) found by in vitro, density functional theory (DFT) calculations, pharmacokinetics prediction and molecular docking are aimed to reveal the interactions on BCA. Firstly, pharmacokinetic predictions of thioalkyl substituted 1,3,4-oxadiazole compounds were generated to predict their potential hazards. Secondly, the predicted molecular docking data and 2D interaction were analyzed based on the best configuration from DFT optimization. Finally, the inhibition against BCA was analyzed in vitro and compared with the theoretical data. The compound (5o) has the best value such as IC50 = 51.80 µM, HOMO–LUMO (ΔE 4.488 Ev), ΔG −7.69 kcal/mol, Full fitness −2152.72 FF and predicted toxicity results showed no significant results except hepatotoxicity.

description: Climate change is disrupting the fundamental conditions of human life and exacerbating existing inequity by placing further burdens on communities that are already vulnerable. Risk exposure varies by where people live and work. In this article, we examine the spatial overlap of the compound risks of COVID-19 and extreme heat in New York City. We assess the relationship between socio-demographic and natural, built and social environmental characteristics, and the spatial correspondence of COVID-19 daily case rates across three pandemic waves. We use these data to create a compound risk index combining heat, COVID-19, density and social vulnerability. Our findings demonstrate that the compound risk of COVID-19 and heat are public health and equity challenges. Heat and COVID-19 exposure are influenced by natural, built, and social environmental factors, including access to mitigation infrastructure. Socio-demographic characteristics are significant indicators of COVID-19 and heat exposure and of where compound vulnerability exists. Using GIS mapping, we illustrate how COVID-19 risk geographies change across the three waves of the pandemic and the particular impact of vaccinations before the onset of the third wave. We, then, use our compound risk index to assess heat interventions undertaken by the City, identify neighborhoods of both adequate and inadequate coverage and provide recommendations for future interventions.

description: Sulphur-containing compounds are highly significant as they can possess a variety of biological activities that make them useful for pharmacological purposes and for the mechanism by which drugs such as antibiotics bind to and disrupt bacterial cell walls. In this study, novel thioalkyl substituted-1,3,4 oxadiazole-bearing sulfonamide compounds have been successfully synthesized and characterized by 1HNMR, 13CNMR, IR and elemental analysis. The effects of different thioalkyl groups on the 1,3,4 oxadiazole group, the IC50 value for Bovine Carbonic Anhydrase (BCA) found by in vitro, density functional theory (DFT) calculations, pharmacokinetics prediction and molecular docking are aimed to reveal the interactions on BCA. Firstly, pharmacokinetic predictions of thioalkyl substituted 1,3,4-oxadiazole compounds were generated to predict their potential hazards. Secondly, the predicted molecular docking data and 2D interaction were analyzed based on the best configuration from DFT optimization. Finally, the inhibition against BCA was analyzed in vitro and compared with the theoretical data. The compound (5o) has the best value such as IC50 = 51.80 µM, HOMO–LUMO (ΔE 4.488 Ev), ΔG −7.69 kcal/mol, Full fitness −2152.72 FF and predicted toxicity results showed no significant results except hepatotoxicity.

description: Computational notebooks (e.g., Jupyter, Google Colab) are widely used by data scientists. A key feature of notebooks is the interactive computing model of iteratively executing cells (i.e., a set of statements) and observing the result (e.g., model or plot). Unfortunately, existing notebook systems do not offer time-traveling to past states: when the user executes a cell, the notebook session state consisting of user-defined variables can be irreversibly modified - e.g., the user cannot 'un-drop' a dataframe column. This is because, unlike DBMS, existing notebook systems do not keep track of the session state. Existing techniques for checkpointing and restoring session states, such as OS-level memory snapshot or application-level session dump, are insufficient: checkpointing can incur prohibitive storage costs and may fail, while restoration can only be inefficiently performed from scratch by fully loading checkpoint files.
 In this paper, we introduce a new notebook system, Kishu, that offers time-traveling to and from arbitrary notebook states using an efficient and fault-tolerant incremental checkpoint and checkout mechanism. Kishu creates incremental checkpoints that are small and correctly preserve complex inter-variable dependencies at a novel Co-variable granularity. Then, to return to a previous state, Kishu accurately identifies the state difference between the current and target states to perform incremental checkout at sub-second latency with minimal data loading. Kishu is compatible with 146 object classes from popular data science libraries (e.g., Ray, Spark, PyTorch), and reduces checkpoint size and checkout time by up to 4.55x and 9.02x, respectively, on a variety of notebooks.
Plant-based research : a queer master's thesis born of mass extinction
Creators: name: Plisic, Melissa
Publisher: name: University of British Columbia
Year: 2024

description: Plant-Based Research concerns kinship-making practices in the context of mass extinction. This research is grounded in queer ecologies and critical animal studies, while aligning with the tenets of feminism, decolonization, critical disability studies, and critical environmental justice. The problem it undertakes is the ways in which settler colonial, cis-heteropatriarchal, white supremacist and anthropocentric approaches to building relationships, or making kin, are fostering mass extinction and climate change. The methodological fuel for this research is multispecies autoethnography, as described by Kathryn Gillespie. Despite auto-ethnography’s egotistical tendencies, “multispecies autoethnography, like humanist autoethnography, is by nature a relational methodology; it signals a focus on the self, but in its multispecies naming necessitates attention to the self in relation to another (or multiple other) species” (Gillespie 3). The “participants” of this research are considered as coconspirators. To co-conspire against something means to work together against it, “it” in this case being white speciesist capitalist cis-heteropatriarchal settler colonialism. “Coconspirator” encapsulates the agencies of multispecies kin, including plants, who communicate by means other than language or sounds (Lawrence 1). The root word “conspire” shares a postal code with “respire”, meaning to breathe; respiration is what connects plants and animals (including humans). We are coconspirators and corespirators. Plant-Based Research is an attempt to unhinge from science-based climate change engagements through its devotion to artistic praxis and attunement to place. The chapters contained in this thesis are a collection of poetry, a zine, a stand-up comedy transcript, a playlist, and more traditional academic prose. This multi-modal, arts-based, and place-based thesis engages the themes of aging and death, plants and gardening, veganism, dogs, disability, astrology, restitution, harm and care, home, friendship, and love. While being generally inconclusive, this thesis invites its readers to critically reflect on the ways in which they make kin, and how they might practice kinship in ways that are antithetical to settler colonial, cis-heteropatriarchal, white supremacist, and anthropocentric modes of being in relationships.

description: Preliminary results of a photon detector combining a Micromegas like multiplier coated with a UV-sensitive CsI photocathode are described. The multiplier is made in a CMOS compatible InGrid technology, which allows to post-process it directly on the surface of an imaging IC. This method is aimed at building light-sensitive imaging detectors where all elements are monolithically integrated. We show that the CsI photocathode deposited in the InGrid mesh does not alter the device performance. Maximum gains of ~6000 were reached in a single-grid element operated in Ar/CH4, with a 2% Ion Back Flow fraction returning to the photocathode.

description: Interplay between magnetization dynamics and electric current in a conducting ferromagnet is theoretically studied based on a microscopic model calculation. First, the effects of the current on magnetization dynamics (spin torques) are studied with special attention to the "dissipative" torques arising from spin-relaxation processes of conduction electrons. Next, an analysis is given of the "spin motive force", namely, a spin-dependent 'voltage' generation due to magnetization dynamics, which is the reaction to spin torques. Finally, an attempt is presented of a unified description of these effects.

Eye movements as a continuous indicator of sensorimotor integration
Creators: name: Kreyenmeier, Philipp
Publisher: name: University of British Columbia
Year: 2024

description: Adaptive behaviour in a highly dynamic and complex environment necessitates the ability to transform sensory input into motor output at different timescales. The goal of this dissertation was to probe the sensorimotor processes that underlie precise movement control in rich sensory environments. In four experimental studies, I studied different types of tracking eye movements in response to stimuli that mirror some of the complexities found in the natural environment (complex pattern motion, target acceleration, and audiovisual signals). In the first study, I investigated the dynamic motion integration processes that give rise to the coherent perception of 2D pattern motion. Comparing eye movements to observers’ perceptual experience revealed shared motion integration mechanisms that drive continuous tracking and motion perception (Chapter 2). Accurate sensing of complex motion signals is a fundamental ability that allows humans to interact with objects moving along complex trajectories. In Chapter 3, I investigated how observers track and manually intercept accelerating targets. Results showed that observers continuously monitor the changing target speed but fail to account for acceleration to predict and intercept targets. Natural interaction with moving visual objects typically involves multiple senses. In two studies, I demonstrated profound and rapid effects of audiovisual integration on goal-directed actions. I found that auditory and visual signals were weighted according to their uncertainty to guide interceptive movements (Chapter 4). Finally, presenting audiovisual distractors during continuous visual tracking revealed multisensory response enhancement of reflexive movement inhibition at short latencies of ~100 milliseconds (Chapter 5). These findings were obtained using eye movements as a continuous indicator of human sensorimotor integration, highlighting the use of eye movements as a model system to study adaptive sensorimotor behaviour in dynamic environments. I propose a model that describes how eye movements at different timescales are affected by the dynamic processing of complex visual and audiovisual signals. The present findings can be used to inform training protocols for interceptive sports athletes and to assess sensorimotor deficits in clinical populations.

description: In this paper, we study coherent exciton transport of continuous-time quantum walks on star graph. Exact analytical results of the transition probabilities are obtained by means of the Gram-Schmidt orthonormalization of the eigenstates. Our results show that the coherent exciton transport displays perfect revivals and strong localization on the initial node. When the initial excitation starts at the central node, the transport on star graph is equivalent to the transport on a complete graph of the same size.
