description: De novo drug design with desired biological activities is crucial for developing novel therapeutics for patients. The drug development process is time and resource-consuming, and it has a low probability of success. Recent advances in machine learning and deep learning technology have reduced the time and cost of the discovery process and therefore, improved pharmaceutical research and development. In this paper, we explore the combination of two rapidly-developing fields with lead candidate discovery in the drug development process. First, Artificial intelligence has already been demonstrated to successfully accelerate conventional drug design approaches. Second, quantum computing has demonstrated promising potential in different applications, such as quantum chemistry, combinatorial optimizations, and machine learning. This manuscript explores hybrid quantum-classical generative adversarial networks (GAN) for small molecule discovery. We substituted each element of GAN with a variational quantum circuit (VQC) and demonstrated the quantum advantages in the small drug discovery. Utilizing a VQC in the noise generator of a GAN to generate small molecules achieves better physicochemical properties and performance in the goal-directed benchmark than the classical counterpart. Moreover, we demonstrate the potential of a VQC with only tens of learnable parameters in the generator of GAN to generate small molecules. We also demonstrate the quantum advantage of a VQC in the discriminator of GAN. In this hybrid model, the number of learnable parameters is significantly less than the classical ones, and it can still generate valid molecules. The hybrid model with only tens of training parameters in the quantum discriminator outperforms the MLP-based one in terms of both generated molecule properties and the achieved KL divergence.

description: We demonstrate how Hahn et al.'s Bayesian Causal Forests model (BCF) can be used to estimate conditional average treatment effects for the longitudinal dataset in the 2022 American Causal Inference Conference Data Challenge. Unfortunately, existing implementations of BCF do not scale to the size of the challenge data. Therefore, we developed flexBCF -- a more scalable and flexible implementation of BCF -- and used it in our challenge submission. We investigate the sensitivity of our results to the choice of propensity score estimation method and the use of sparsity-inducing regression tree priors. While we found that our overall point predictions were not especially sensitive to these modeling choices, we did observe that running BCF with flexibly estimated propensity scores often yielded better-calibrated uncertainty intervals.

description: Managing light-matter interactions on timescales faster than the loss of electronic coherence is key for achieving full quantum control of the final products in solid-solid transformations. In this work, we demonstrate coherent electronic control of the photoinduced insulator-to-metal transition in the prototypical Mott insulator V$_2$O$_3$. Selective excitation of a specific interband transition with two phase-locked light pulses manipulates the orbital occupation of the correlated bands in a way that depends on the coherent evolution of the photoinduced superposition of states. A comparison between experimental results and numerical solutions of the optical Bloch equations provides an electronic coherence time on the order of 5 fs. Temperature-dependent experiments suggest that the electronic coherence time is enhanced in the vicinity of the insulator-to-metal transition critical temperature, thus highlighting the role of fluctuations in determining the electronic coherence. These results open new routes to selectively switch the functionalities of quantum materials and coherently control solid-solid electronic transformations.
Captured audio : resource extraction and the collection, stewardship, and return of Nuxalk sound recordings
Creators: name: Leischner, Emily Jean
Publisher: name: University of British Columbia
Year: 2024

description: Following the circulation of recorded Nuxalk voices in archives and museums, this dissertation examines moments where the collection, stewardship, and return of sound recordings overlaps with logics of resource extraction. To do this, I use community-based heritage research to partner with Nuxalk organizations, colleagues, and friends on community-led projects. With Nuxalk Radio, I co-created a series on the history of museum collecting called “Using and Refusing Museums” and facilitated returning copies of Nuxalk sound recordings at the Royal British Columbia Museum and the Canadian Museum of History. Throughout, I define recordings of Indigenous voices that circulate outside of their originating communities, removed from their authority and control, as captured audio. Theorizing captured audio through four case studies (1) reveals how recorded Indigenous voices undergo a social, material, and political process of transformation when they are taken outside of their originating communities, and (2) illustrates opportunities for disrupting the logic of Indigenous-voice-as-resource through experimental, community-engaged, and anti-extractive methods. Examining the research practices of the first person to record Nuxalk voices, anthropologist Thomas F. McIlwraith, I demonstrate how the history of museum collecting in Canada is entangled with extractive industries. By interviewing museum and archival staff, and taking seriously the positive reputation McIlwraith has in Nuxalk territory today, I argue that extractive logics are not deterministic or unavoidable. Placing the experiences of multiple generations of researchers and their Nuxalk collaborators in conversation, I examine how research methods – from the creation of captured audio to reciprocal relationships – emerge and persist across time. Drawing attention to the everyday ways staff both resist and reproduce extractive logics, I show that fragmenting settler legal regimes is a productive strategy for re-instating Indigenous authority in archives and museums using Indigenous laws. Interrogating university research practices, I argue that the academy is also implicated in the ongoing creation of captured audio. Nevertheless, it is possible to co-create audio recordings in the context of academic research that does not replicate the same process of transformation that captured audio undergoes. Taking a critical approach to my own audial research methodologies, I demonstrate that anti-extractive scholarship is worth striving for.

description: Deep learning technology has made great progress in multi-view 3D reconstruction tasks. At present, most mainstream solutions establish the mapping between views and shape of an object by assembling the networks of 2D encoder and 3D decoder as the basic structure while they adopt different approaches to obtain aggregation of features from several views. Among them, the methods using attention-based fusion perform better and more stable than the others, however, they still have an obvious shortcoming -- the strong independence of each view during predicting the weights for merging leads to a lack of adaption of the global state. In this paper, we propose a global-aware attention-based fusion approach that builds the correlation between each branch and the global to provide a comprehensive foundation for weights inference. In order to enhance the ability of the network, we introduce a novel loss function to supervise the shape overall and propose a dynamic two-stage training strategy that can effectively adapt to all reconstructors with attention-based fusion. Experiments on ShapeNet verify that our method outperforms existing SOTA methods while the amount of parameters is far less than the same type of algorithm, Pix2Vox++. Furthermore, we propose a view-reduction method based on maximizing diversity and discuss the cost-performance tradeoff of our model to achieve a better performance when facing heavy input amount and limited computational cost.

description: Soft set theory, instituted by Molodsov is a robust mathematical tool for dealing with uncertainties and problems that are questionably de?ned. Our aim in this paper is to broaden soft theory by studying some new algebraic operations (product and product divisions) on soft quasigroups. We de?fined soft quasigroups and introduce different algebraic properties connected with them. It was shown that for soft quasigroups over medial quasigroups, the resulting soft sets based on product and product divisionsare also soft quasigroups over medial quasigroups. With the new operations de?nedon soft quasigroups, it was shown that these new operations are distributive overrestricted/extended union and intersection operations.

description: Packet loss concealment (PLC) is a tool for enhancing speech degradation caused by poor network conditions or underflow/overflow in audio processing pipelines. We propose a real-time recurrent method that leverages previous outputs to mitigate artefact of lost packets without the prior knowledge of loss mask. The proposed full-band recurrent network (FRN) model operates at 48 kHz, which is suitable for high-quality telecommunication applications. Experiment results highlight the superiority of FRN over an offline non-causal baseline and a top performer in a recent PLC challenge.

description: We present a new streaming algorithm to validate JSON documents against a set of constraints given as a JSON schema. Among the possible values a JSON document can hold, objects are unordered collections of key-value pairs while arrays are ordered collections of values. We prove that there always exists a visibly pushdown automaton (VPA) that accepts the same set of JSON documents as a JSON schema. Leveraging this result, our approach relies on learning a VPA for the provided schema. As the learned VPA assumes a fixed order on the key-value pairs of the objects, we abstract its transitions in a special kind of graph, and propose an efficient streaming algorithm using the VPA and its graph to decide whether a JSON document is valid for the schema. We evaluate the implementation of our algorithm on a number of random JSON documents, and compare it to the classical validation algorithm.

Vacuum-UV/chlorine advanced oxidation process for micropollutants removal in potable reuse trains
Creators: name: Masjoudi, Mahsa
Publisher: name: University of British Columbia
Year: 2024

description: Access to clean drinking water is a critical issue in many regions of the world due to rapid urbanization, population growth, and climate change. To address this challenge, potable water reuse has emerged as a viable solution, which involves recycling wastewater to produce high-quality drinking water using a multi-barrier approach including micro- or ultra-filtration, reverse osmosis (RO), and advanced oxidation processes (AOPs). As the final step of this process, AOPs play a crucial role by providing effective disinfection and elimination of micropollutants. Thus, enhancements in AOP technology further improve the quality of recycled water and make the reuse strategy more feasible for communities facing water scarcity. This research investigated the application of vacuum-UV (VUV) as an alternative AOP for treating micropollutants, 1,4-dioxane (1,4-D) and carbamazepine (CBZ), under potable reuse conditions. Kinetic studies were performed in various water matrices, accounting for the presence of monochloramine and free chlorine oxidants, as well as relevant operational parameters. VUV AOPs have the potential to achieve high treatment efficacy by directly breaking down water molecules at 185 nm, resulting in the generation of •OH. The addition of free chlorine or monochloramine individually hindered the removal of 1,4-D in the corresponding VUV AOPs. However, chlorination of chloramine-containing water significantly improved both the treatment performance and energy efficiency of the AOP. Additionally, the presence of water constituents such as bicarbonate, chloride, and organic matter reduced micropollutants degradation rates. Nevertheless, lower chloride levels were found to improve 1,4-D removal in the presence of free chlorine or chloramine oxidants by promoting the formation of Cl₂•-. In an actual RO permeate matrix, VUV AOPs demonstrated a superior treatment performance for 1,4-D removal compared to the conventionally used UV/H₂O₂ and UV/Cl₂ AOPs. Lastly, kinetic studies and modeling revealed that •OH and Cl₂•- species played a significant role in driving the degradation reactions in the VUV/Cl₂/Chloramine AOP. Overall, this study highlights the potential of VUV AOPs, particularly VUV/Cl₂/Chloramine, as an effective treatment technology for removing micropollutants from water and supporting potable reuse systems.

description: Quantum dynamics can be simulated on a quantum computer by exponentiating elementary terms from the Hamiltonian in a sequential manner. However, such an implementation of Trotter steps has gate complexity depending on the total Hamiltonian term number, comparing unfavorably to algorithms using more advanced techniques. We develop methods to perform faster Trotter steps with complexity sublinear in the number of terms. We achieve this for a class of Hamiltonians whose interaction strength decays with distance according to power law. Our methods include one based on a recursive block encoding and one based on an average-cost simulation, overcoming the normalization-factor barrier of these advanced quantum simulation techniques. We also realize faster Trotter steps when certain blocks of Hamiltonian coefficients have low rank. Combining with a tighter error analysis, we show that it suffices to use $\left(η^{1/3}n^{1/3}+\frac{n^{2/3}}{η^{2/3}}\right)n^{1+o(1)}$ gates to simulate uniform electron gas with $n$ spin orbitals and $η$ electrons in second quantization in real space, asymptotically improving over the best previous work. We obtain an analogous result when the external potential of nuclei is introduced under the Born-Oppenheimer approximation. We prove a circuit lower bound when the Hamiltonian coefficients take a continuum range of values, showing that generic $n$-qubit $2$-local Hamiltonians with commuting terms require at least $Ω(n^2)$ gates to evolve with accuracy $ε=Ω(1/poly(n))$ for time $t=Ω(ε)$. Our proof is based on a gate-efficient reduction from the approximate synthesis of diagonal unitaries within the Hamming weight-$2$ subspace, which may be of independent interest. Our result thus suggests the use of Hamiltonian structural properties as both necessary and sufficient to implement Trotter steps with lower gate complexity.

description: High-density structures of sub-surface phosphorus dopants in silicon continue to garner interest as a silicon-based quantum computer platform, however, a much-needed confirmation of their dopant arrangement has been lacking. In this work, we take advantage of the chemical specificity of X-ray photoelectron diffraction to obtain the precise structural configuration of P dopants in sub-surface Si:P $δ$-layers. The growth of $δ$-layer systems with different levels of doping is carefully studied and verified using X-ray photoelectron spectroscopy and low-energy electron diffraction. Subsequent XPD measurements reveal that in all cases, the dopants primarily substitute with Si atoms from the host material. Furthermore, no signs of free carrier-inhibiting P$-$P dimerization can be observed. Our observations not only settle a nearly decade-long debate about the dopant arrangement but also demonstrate that XPD is well suited to study sub-surface dopant structures. This work thus provides valuable input for an updated understanding of the behavior of Si:P $δ$-layers and the modeling of their derived quantum devices.

description: We introduce a methodology and investigate the feasibility of measuring quantum properties of tau lepton pairs in the $H \to τ^+ τ^-$ decay at future lepton colliders. In particular, observation of entanglement, steerability and violation of Bell inequalities are examined for the ILC and FCC-ee. We find that detecting quantum correlation crucially relies on precise reconstruction of the tau lepton rest frame and a simple kinematics reconstruction does not suffice due to the finite energy resolution of the colliding beams and detectors. To correct for energy mismeasurements, a log-likelihood method is developed that incorporates the information of impact parameters of tau lepton decays. We demonstrate that an accurate measurement of quantum properties is possible with this method. As a by-product, we show that a novel model-independent test of CP violation can be performed and the CP-phase of $H ττ$ interaction can be constrained with an accuracy comparable to dedicated analyses, i.e., up to $7.9^{\circ}$ and $5.4^{\circ}$ at ILC and FCC-ee, respectively.

Behavioural effects of novel clinical candidate drugs, l-tetrahydropalmatine (l-THP) and Z944, on morphine withdrawal-induced hyperalgesia

description: Opioid use disorder (OUD) is a major contributor to drug-related deaths worldwide. Opioid use cessation causes severe withdrawal symptoms, including prominent hyperalgesia – a contributor to the negative reinforcement of drug taking. Effective pain control is an underappreciated aspect of managing opioid withdrawal, and its absence presents a significant barrier to successful opioid detoxification. Exploring analgesic interventions for withdrawal-induced hyperalgesia may reveal novel OUD therapies. This thesis describes a model of hyperalgesia in both acute and extended withdrawal in morphine-dependent animals and the effect of two clinical candidate analgesic drugs on withdrawal-induced hyperalgesia. l-Tetrahydropalmatine (l-THP) is a tetrahydroprotoberberine compound and active ingredient of a botanical formulation used in Vietnam for OUD treatment with preclinical efficacy in neuropathic pain models. Z944 is a selective T-type calcium channel antagonist undergoing clinical trials as an anticonvulsive and analgesic. To establish drug dependence modelling intermittent access during abuse scenarios, morphine (15 mg/kg, i.p.) was given once a day, 5 days/week and Von Frey tests were conducted 2-3 times a week ~23 h after morphine injection. Animals subjected to three weeks of morphine treatment experienced a ~30% reduction in pain tolerance. To model hyperalgesia during detoxification, animals entered abstinence after 3 weeks of morphine treatment and with Von Frey testing showing that hyperalgesia was persistent for 14 days before spontaneous recovery. Both l-THP (5 or 7.5 mg/kg, p.o.) and Z944 (10 mg/kg, p.o.) were effective at attenuating hyperalgesia during acute withdrawal. Seven-day treatment with l-THP (5 mg/kg) or Z944 (10 mg/kg) in morphine-dependent animals undergoing extended withdrawal resulted in a significant increase in paw retraction thresholds compared to controls and this effect persisted after the completion of treatment. Importantly, the improvement in pain tolerance remained after treatment completion, hastening pain tolerance recovery to baseline by 61% and 80% (l-THP and Z944, respectively). Neither candidate drug influenced mechanical sensitivity in morphine-naïve animals. Overall, these findings support the hypothesis that pain management during detoxification is necessary for improved treatment outcomes. l-THP and Z944, therefore, may be a valuable addition to the currently limited arsenal of opioid detoxification treatments.

description: Complex networks play a fundamental role in understanding phenomena from the collective behavior of spins, neural networks, and power grids to the spread of diseases. Topological phenomena in such networks have recently been exploited to preserve the response of systems in the presence of disorder. We propose and demonstrate topological structurally disordered systems with a modal structure that enhances nonlinear phenomena in the topological channels by inhibiting the ultrafast leakage of energy from edge modes to bulk modes. We present the construction of the graph and show that its dynamics enhances the topologically protected photon pair generation rate by an order of magnitude. Disordered nonlinear topological graphs will enable advanced quantum interconnects, efficient nonlinear sources, and light-based information processing for artificial intelligence.

description: Efficient detection of single optical centers in solids is essential for quantum information processing, sensing, and single-photon generation applications. In this work, we use radio-frequency (RF) reflectometry to electrically detect the photoionization induced by a single Er$^{3+}$ ion in Si. The high bandwidth and sensitivity of the RF reflectometry provide sub-100-ns time resolution for the photoionization detection. With this technique, the optically excited state lifetime of a single Er$^{3+}$ ion in a Si nano-transistor is measured for the first time to be 0.49 $\pm$ 0.04 $μ$s. Our results demonstrate an efficient approach for detecting a charge state change induced by Er excitation and relaxation. This approach could be used for fast readout of other single optical centers in solids and is attractive for large-scale integrated optical quantum systems thanks to the multi-channel RF reflectometry demonstrated with frequency multiplexing techniques.

description: Fracton phases are a particularly exotic type of quantum spin liquids where the elementary quasiparticles are intrinsically immobile. These phases may be described by unconventional gauge theories known as tensor or multipolar gauge theories, characteristic for so-called type-I or type-II fracton phases, respectively. Both variants have been associated with distinctive singular patterns in the spin structure factor, such as multifold pinch points for type-I and quadratic pinch points for type-II fracton phases. Here, we assess the impact of quantum fluctuations on these patterns by numerically investigating the spin $S=1/2$ quantum version of a classical spin model on the octahedral lattice featuring exact realizations of multifold and quadratic pinch points, as well as an unusual pinch line singularity. Based on large scale pseudo fermion and pseudo Majorana functional renormalization group calculations, we take the intactness of these spectroscopic signatures as a measure for the stability of the corresponding fracton phases. We find that in all three cases, quantum fluctuations significantly modify the shape of pinch points or lines by smearing them out and shifting signal away from the singularities in contrast to effects of pure thermal fluctuations. This indicates possible fragility of these phases and allows us to identify characteristic fingerprints of their remnants.

description: We predict a novel metallic state of matter that emerges in a Weyl-semimetal superstructure with spatially varying Weyl-node positions. In the new state, the Weyl nodes are stretched into extended, anisotropic Fermi surfaces, which can be understood as being built from Fermi arc-like states. This "Fermi-arc metal" exhibits the chiral anomaly of the parental Weyl semimetal. However, unlike in the parental Weyl semimetal, in the Fermi-arc metal the "ultra-quantum state", in which the anomalous chiral Landau level is the only state at the Fermi energy, is already reached for a finite energy window at zero magnetic field. The dominance of the ultra-quantum state implies a universal low-field ballistic magnetoconductance and the absence of quantum oscillations, making the Fermi surface "invisible" to de Haas-van Alphen and Shubnikov-de Haas effects, although it signifies its presence in other response properties.

Understanding the treatment disparities in college students experiencing mental health problems : a meta-analysis and regression analysis
Creators: name: Pei, Julia
Publisher: name: University of British Columbia
Year: 2023

description: College students experience high rates of mental health problems. While college contexts can provide an opportunity for early intervention, college students report low treatment rates. Further, a range of sociodemographic disparities in the rates of mental health treatment among students experiencing mental health problems have been identified. This thesis aimed to quantify the magnitude of these treatment disparities, identify the sub-groups of students experiencing the largest treatment disparities, and identify the stage(s) of the treatment-seeking pathway through which these disparities emerge. First, a systematic review and meta-analysis of the literature was conducted. Pooled prevalence ratios of receiving treatment, conditional on experiencing a mental health problem, were calculated for each sociodemographic disparity identified in the literature. Next, a regression analysis of survey data from four Canadian universities was conducted to quantify the disparities at two stages of the treatment-seeking pathway, among students experiencing a mental health problem. Odds ratios of 1) having a perceived need for treatment and 2) receiving treatment, conditional on having a perceived need were calculated for a range of sociodemographic characteristics. The first study identified a range of significant sociodemographic disparities in the treatment rates of students experiencing mental health problems, with the largest disparities based on race and ethnicity, international student status, sex, and gender. Results from the second study suggest that disparities based on gender, sexual orientation, race, ethnicity, age, and parental education emerge through differences at both stages of the treatment pathway, whereas disparities based on international student status and level of financial stress predominately emerge through differences at the second stage of the pathway. Together, these findings highlight the need for targeted efforts to promote equitable access to mental health treatment in student populations and inform the sub-groups and corresponding stages of the treatment-seeking pathway to target in said efforts.
