description: Rotationally invariant combinations of the Brillouin zone-center Bloch functions are used as basis function to express in cylindrical coordinates the valence-band and Kane envelope-function Hamiltonians for wurtzite and zinc-blende semiconductor heterostructures. For cylindrically symmetric systems, this basis allows to treat the envelope functions as eigenstates of the operator of projection of total angular momentum on the symmetry axis, with the operator's eigenvalue conventionally entering the Hamiltonians as a parameter. Complementing the Hamiltonians with boundary conditions for the envelope functions on the symmetry axis, we present for the first time a complete formalism for efficient modeling and description of multiband electron states in low-dimensional semiconductor structures with cylindrical symmetry. To demonstrate the potency of the cylindrical symmetry approximation and establish a criterion of its applicability for actual structures, we map the ground and several excited valence-band states in an isolated wurtzite GaN quantum wire of a hexagonal cross-section to the states in an equivalent quantum wire of a circular cross-section.

Stability of implants placed at sites treated with bone allograft
Creators: name: Tuckey, Tanya Danielle
Publisher: name: University of British Columbia
Year: 2012

description: Objective: A retrospective chart review was performed to assess the stability of implants in a variety of clinical situations, including placement at sites with a history of bone augmentation using bone allograft. Methods: The study included 286 implants placed by an experienced practitioner and by Graduate Periodontics residents at the University of British Columbia. Implants included a variety of Nobel Biocare, Straumann, and Astra Tech designs. The Osstell ISQ device was used to measure implant stability (RFA) by emitting magnetic pulses that cause a SmartPeg attached to the implant to resonate according to the stability of the implant. Results were displayed in Implant Stability Quotient (ISQ) units and were recorded in triplicate, from the buccal, lingual, mesial, and distal. Measurements obtained at second surgery were compared with factors related to bone grafting, as well as patient demographics, implant site, and physical implant characteristics (significance p<0.05). Results: The overall implant survival rate was 98.9% with 3 implant failures. There was good reproducibility of measurements taken in triplicate and measurements taken from the buccal were significantly lower than those taken from either the mesial or distal. A significantly higher ISQ was obtained in the mandible than the maxilla, with significantly lower values at incisor sites compared with both premolar and molar sites. A higher ISQ was obtained for short implants and this reached statistical significance in the mandible, where shorter implants tended to be wider. Significantly lower ISQ values were obtained for narrow implants in both arches. ISQ values in soft bone were significantly lower, as were values at sites with a history of lateral ridge augmentation using xenograft. No significant difference was observed between ISQ and age, gender, Type 2 diabetes, smoking, implant type, insertion torque, buccal bony dehiscence, surgeon’s level of experience, or whether the site had a history of lateral ridge augmentation, socket preservation, or sinus lifting. Conclusions: Implant stability, as measured using the Osstell ISQ device, is not significantly affected by a history of bone grafting using bone allograft. Stability is, however, affected by implant dimensions, implant site, and bone density.

description: We investigate theoretically the properties of the photon state and the electronic transport in a system consisting of a metallic quantum dot strongly coupled to a superconducting microwave transmission line cavity. Within the framework of circuit quantum electrodynamics we derive a Hamiltonian for arbitrary strong capacitive coupling between the dot and the cavity. The dynamics of the system is described by a quantum master equation, accounting for the electronic transport as well as the coherent, non-equilibrium properties of the photon state. The photon state is investigated, focusing on, for a single active mode, signatures of microwave polaron formation and the effects of a non-equilibrium photon distribution. For two active photon modes, intra mode conversion and polaron coherences are investigated. For the electronic transport, electrical current and noise through the dot and the influence of the photon state on the transport properties are at the focus. We identify clear transport signatures due to the non-equilibrium photon population, in particular the emergence of superpoissonian shot-noise at ultrastrong dot-cavity couplings.

description: To harness the potential of quantum computing, increasing the number of quantum units, a process known as scaling, is critical. Whereas qubits have traditionally been used as the units for quantum computing, the development of multi-level systems (qudits), which offer larger Hilbert spaces and advantages over qubits in cryptography and circuit complexity reduction, requires new methods to characterise the quality of quantum gates and ensure safe scaling. Randomised benchmarking offers a simple and inexpensive method for this characterisation. This thesis reports advances in the characterisation of universal single- and multi-qudit gates. I introduce the characterisation of universal qutrit gates through the definition of an optimal scheme that requires similar experimental resources as the standard method for non- universal gates. The feasibility of my qutrit scheme is tested numerically using parameters from experimental qutrit implementations. I then generalise my qutrit results and devise a general scheme for a qudit system with arbitrary d. Because using the same construction for qudits with d > 3 as in the qutrit case leads to more than two parameters, a different strategy was necessary. I note that my qudit characterisation obtains an estimate of the average error per gate; thus, this characterisation is collective. A more realistic characterisation requires estimating the average gate fidelity of a single non-Clifford gate. In the last part, I generalise my qudit method to individually, in contrast to the previous collective result, characterise non-Clifford gates. My schemes are relevant to at least two communities: experimental groups with a qudit platform, as my work effectively characterises a complete gate set, and randomised bench- marking theorists, who may be interested both in the gate set I introduce and in the schemes I developed.

description: Background
                With numerous and fast approvals of different agents including immune checkpoint inhibitors, monoclonal antibodies, or chimeric antigen receptor (CAR) T-cell therapy, immunotherapy is now an established form of cancer treatment. These agents have demonstrated impressive clinical activity across many tumor types, but also revealed different toxicity profiles and mechanisms of action. The classic assumptions imposed by cytotoxic agents may no longer be applicable, requiring new strategies for dose selection and trial design.

                Description
                This main goal of this article is to summarize and highlight main challenges of early-phase study design of immunotherapies from a statistical perspective. We compared the underlying toxicity and efficacy assumptions of cytotoxic versus immune-oncology agents, proposed novel endpoints to be included in the dose-selection process, and reviewed design considerations to be considered for early-phase trials. When available, references to software and/or web-based applications were also provided to ease the implementation. Throughout the paper, concrete examples from completed (pembrolizumab, nivolumab) or ongoing trials were used to motivate the main ideas including recommendation of alternative designs.

                Conclusion
                Further advances in the effectiveness of cancer immunotherapies will require new approaches that include redefining the optimal dose to be carried forward in later phases, incorporating additional endpoints in the dose selection process (PK, PD, immune-based biomarkers), developing personalized biomarker profiles, or testing drug combination therapies to improve efficacy and reduce toxicity.

description: Based on a continuum mechanical model for single-layer graphene we propose and analyze a microscopic mechanism for dissipation in nanoelectromechanical graphene resonators. We find that coupling between flexural modes and in-plane phonons leads to linear and nonlinear damping of out-of-plane vibrations. By tuning external parameters such as bias and ac voltages, one can cross over from a linear to a nonlinear-damping dominated regime. We discuss the behavior of the effective quality factor in this context.

title: Predicting Hemorrhage in ICU Patients with Deep Learning Techniques

Publisher: name: Graduate Studies

Subjects: subject: Engineering--Mechanical

description: Hemorrhage is a leading cause of trauma-related mortality, making early prediction of blood transfusion needs critical for timely intervention. This thesis investigates the application of data-driven modeling techniques to predict hemorrhage in intensive care unit (ICU) patients, aiming to improve patient outcomes through early-stage detection. We developed a Long Short-Term Memory (LSTM)-based architecture to model sequential patient data, capturing the dynamic evolution of vital signs and interventions to predict hemorrhage within a 5-hour window. By using irregularly sampled time series data, Our model achieved an Area Under the Curve (AUC) of 0.99, surpassing existing literature, where AUC values typically range from 0.70 to 0.95. We also compared the performance of our LSTM model with a time series Transformer, finding that LSTM outperformed the Transformer architecture in this study. A key contribution of this research is the comparative analysis of imputation methods, evaluating their impact on data distribution and prediction performance. While imputation techniques significantly altered data distribution, their effect on prediction performance was minimal. Additionally, Shapley values were employed to interpret the model, revealing feature contributions that aligned with surgeons’ understanding of hemorrhage mechanisms, further validating the model. To test external validity, we applied the ICU-trained model to prehospital datasets collected locally in collaboration with Shock Trauma Air Rescue Service (STARS). Although differences in data distribution posed challenges to maintaining high performance outside ICU settings, this research highlights the potential of sequential modeling in hemorrhage prediction and paves the way for future improvements in prehospital care.

description: We use a quantum Monte Carlo method to investigate various classes of 2D spin models with long-range interactions at low temperatures. In particular, we study a dipolar XXZ model with U(1) symmetry that appears as a hard-core boson limit of an extended Hubbard model describing polarized dipolar atoms or molecules in an optical lattice. Tunneling, in such a model, is short-range, whereas density-density couplings decay with distance following a cubic power law. We investigate also an XXZ model with long-range couplings of all three spin components - such a model describes a system of ultracold ions in a lattice of microtraps. We describe an approximate phase diagram for such systems at zero and at finite temperature, and compare their properties. In particular, we compare the extent of crystalline, super?uid, and supersolid phases. Our predictions apply directly to current experiments with mesoscopic numbers of polar molecules and trapped ions.

description: Despite well-established health benefits, nearly half of adults in Canada do not engage in enough physical activity for optimal health benefits. In Canada there are differences in physical activity levels among immigrants and non-immigrants. The built environment has the potential to reduce or widen inequalities if its effects on physical activity differ among population subgroups. While evidence has highlighted potential differences in how the built environment is associated with physical activity across various population subgroups, some equity-seeking groups, such as immigrants, have received little research attention. Globally, most studies examining this association among immigrants have been conducted in the U.S., with inconsistent findings. The study presented in this thesis addresses these knowledge gaps, guided by two relevant theoretical perspectives, including the socioecological model and acculturation theory. The aim of this research was to generate novel evidence regarding the associations between the neighbourhood built environment, specifically objectively-measured walkability, and physical activity according to residency status (Canadian-born, recent immigrants, and established immigrants). Our objectives were 1) to estimate and compare TPA and LPA participation and duration between Canadian-born, recent and established immigrant adults and determine whether neighbourhood walkability accounts for any observed residency group differences, and 2) to estimate and compare the direction and magnitude of associations between neighbourhood walkability and TPA and LPA participation and duration between these groups. The study included cross-sectional analysis of nationally representative data from Canadian Community Health survey (CCHS 2017-2018) linked with 2016 Can-ALE data. We found that recent and established immigrants were more likely than Canadian-born to participate in TPA, but these differences attenuated after controlling for walkability. Moreover, recent and established immigrants were less likely to participate in LPA and undertook fewer LPA minutes, compared to Canadian-born individuals. However, the differences in LPA minutes attenuated after controlling for walkability. Walkability was positively associated with TPA participation and duration in all residency status groups, but the magnitude of these associations differed between these groups. Findings from this thesis suggest that improving neighbourhood walkability could have broad public health benefits, but tailored strategies are essential to address the needs of immigrant populations.
title: Design of Phase Shifters for Phased Array Antenna Applications
Creators: name: Jebeli Haji Abadi, Ali
Publisher: name: Graduate Studies
Year: 2024
Subjects: subject: Engineering--Electronics and Electrical

description: This thesis presents a method for reducing the complexity of the I-Q phase shifter. This new method is based on the I-Q phase shifter architecture, where the input signal is divided into two orthogonal paths. By adjusting the amplitude of these two signals and then combining them, a signal with a phase difference relative to the input signal is obtained. The variable attenuators used in this method must be adjusted based on the required phase shift, and these attenuators are controlled by the system's control unit through multiple control lines. By reducing the number of control lines in this phase shifter, we effectively decrease the complexity and load on the control section. In this work, we first introduce a Voltage Variable Gamma Phase Shifter. This phase shifter requires only one control line and provides continuous phase variation. In this approach, the input divider is replaced with a circulator, and the two attenuators are replaced with a single variable resistor. The variable resistor is a PIN diode, controlled by a single control line. This phase shifter was fabricated and tested at 3.45 GHz with a bandwidth of 300 MHz. It provided approximately 95 degrees of phase change, with insertion loss less than 14 dB. The limitation of this method is the circulator, which prevents its use in Microwave Monolithic Integrated Circuits (MMIC). To address this issue, we have developed the next version of this phase shifter. The second step in this thesis involves modifying the Voltage Variable Gamma Phase Shifter to make it suitable for MMIC applications. To achieve this, we replace the input circulator with a coupler. This method has its own pros and cons. Although this version can be used in MMIC applications, we do not have control over both paths, which means we will lose the ability to vary the phase. In this configuration, since we have control over only 50 percent of the input signal, we will lose at least 50 percent of the phase variation. This phase shifter has been fabricated and tested at 3 GHz with a bandwidth of 400 MHz. The final step is the MMIC version of this phase shifter. Using a GaN substrate and 250 µm technology, we designed the MMIC phase shifter using the process design kit (PDK) from United Monolithic Semiconductor (UMS).This phase shifter provides a phase variation of 40 degrees and a bandwidth of 400 MHz at 3.5 GHz, with an insertion loss of less than 8 dB. The dimension of the final version of this phase shifter is 2 by 1.6 mm.

description: It is shown that in degenerate magnetized Fermi-Dirac plasma where the electron-orbital are quantized distinct quantum hydrodynamic (QHD) limits exist in which the nonlinear density waves behave differently. The Coulomb interaction among degenerate electrons affect the electrostatic nonlinear wave dynamics more significant in the ground-state Landau quantization or the so-called quantum-limit ($l=0$) rather than in the classical-limit ($l=\infty$). It is also remarked that the effective electron quantum potential unlike the number-density and degeneracy pressure is independent of the applied magnetic field in the classical-limit plasma, while, it depends strongly on the field strength in the quantum-limit. Current findings are equally important in the study of wave dynamics in arbitrarily-high magnetized astrophysical and laboratory dense plasmas.

description: Electrospinning provides an effective method for generating nanofibers from solution of carboxymethyl chitosan/polyoxyethylene oxide (CMCS/PEO). The goal of this work is to explore the potential application of electrospun CMCS/PEO nanofiber membrane in fruit fresh-keeping. The microstructure, antibacterial activity, hydrophilia, and air permeability of the nanofiber membrane have been tested. For comparison, the fresh-keeping effects of commercial cling wrap and CMCS/PEO nanofiber membranes on strawberries’ rotting rate and weight loss rate have been studied. The results indicate that the electrospun CMCS/PEO membrane could effectively avoid water loss in strawberries and has a remarkable effect to prolong strawberries’ shelf life due to its breathability and antibacterial activity. In addition, the composite CMCS/PEO, nanofiber membrane is non-poisonous and edible, which can be used in food industry.

description: Soap holes are discrete occurrences of fluidized sediments that have been reduced to zero effective stress resulting in quick conditions. These features can be detrimental to farming operations through evaporitic concentration of ions in surface sediments surrounding the features or by fatally trapping livestock. Currently, the sediment properties and subsurface conditions required to generate soap holes are relatively unknown. A site investigation conducted near Didsbury, Alberta, analyzed the geologic, hydrogeologic and geotechnical conditions surrounding four active soap hole features to improve the understanding of soap hole formation. Glacially derived surface sediments and Paskapoo formation bedrock were extensively analyzed using a combination electrical resistivity tomography (ERT), cone penetration testing (CPT), and sediment coring and sampling. Laboratory analyses were completed on recovered sediment samples to determine index properties, particle-size distribution, Atterberg consistency limits, dispersive properties and chemical composition. ERT transects indicated there are three distinct sedimentary units on-site, and bedrock depth of approximately 11-mbgs, which was confirmed by drilling. Near-surface sediments are primarily comprised of non-sensitive, over-consolidated fine-grained material, with medium to high plasticity, and are highly dispersive. Discontinuous coarse-grains sediments were also noted in the sediment core, potentially providing flow-paths through the extensive fine-grained sediments. Hydrogeologic conditions were analyzed utilizing pressure transducer data, manual water level measurements, CPT correlations, and single well response tests. Artesian conditions were confirmed within a soap hole feature that was instrumented on site and are suspected to persist in the surrounding features. Pore pressures within and below the instrumented feature correlate with regional potentiometric surface maps of the Paskapoo formation, suggesting hydraulic connection to deep groundwater flow-paths. Strong upward vertical gradients (>1-m/m) within the soap hole feature exceed the critical gradient of surrounding sediments. Downward vertical gradients less than critical were found in most background sediments surrounding the features. Overall, sediments at the study site did not have properties indicative of being prone to liquefication. However, results suggest that high pore pressures, dispersive soils and vertical hydraulic gradients exceeding sediment critical gradients are some of the primary formation mechanisms of the soap hole features.

description: We derive and employ a semi-classical Langevin equation obtained from path-integrals to describe the ionic dynamics of a molecular junction in the presence of electrical current. The electronic environment serves as an effective non-equilibrium bath. The bath results in random forces describing Joule heating,current-induced forces including the non-conservative wind force,dissipative frictional forces, and an effective Lorentz-like force due to the Berry phase of the non-equilibrium electrons. Using a generic two-level molecular model, we highlight the importance of both current-induced forces and Joule heating for the stability of the system. We compare the impact of the different forces, and the wide-band approximation for the electronic structure on our result. We examine the current-induced instabilities (excitation of runaway "waterwheel" modes) and investigate the signature of these in the Raman signals.

description: We address here the problem of extending the Pesin relation among positive Lyapunov exponents and the Kolmogorov-Sinai entropy to the case of dynamical systems exhibiting subexponential instabilities. By using a recent rigorous result due to Zweimüller, we show that the usual Pesin relation can be extended straightforwardly for weakly chaotic one-dimensional systems of the Pomeau-Manneville type, provided one introduces a convenient subexponential generalization of the Kolmogorov-Sinai entropy. We show, furthermore, that Zweimüller's result provides an efficient prescription for the evaluation of the algorithm complexity for such systems. Our results are confirmed by exhaustive numerical simulations. We also point out and correct a misleading extension of the Pesin relation based on the Krengel entropy that has appeared recently in the literature.

description: Our previous study of a system of bodies assumed to move along almost circular orbits around a central mass, approximately described by Hill's equations, is extended to "exotic" [alias non-commutative] particles. For a certain critical value of the angular velocity, the only allowed motions follow the Hall law. Translations and generalized boosts span two independent Heisenberg algebras with different central parameters. In the critical case, the symmetry reduces to a single Heisenberg algebra.

description: Research demonstrates the importance of father-child relationships in the early years and the effects on children’s development. Recent studies have found positive associations between father-child interactions and young children’s social emotional development, academic achievement, self-regulation and language development. Recognizing the important role that fathers play in their children’s development, there has been a growing focus on engaging fathers in early childhood education programs.

Father engagement in early childhood programs (ECPs) has been defined as “…direct and indirect connections that fathers have with ECPs including selecting programs, participating in program-related activities, assuming responsibility for children’s health and well-being in the program, and supporting joint program and family goals.” Research on father engagement in ECPs focuses on defining and measuring father engagement, examining fathers’ beliefs and barriers to engagement, father engagement for children with disabilities, child care decision-making by fathers, and interventions to engage fathers in early childhood programs (such as home visiting, Early Head Start, and Head Start). Additionally, more recent research focuses on culturally responsive approaches to father engagement in ECPs.

This resource list includes research on father engagement in ECPs from 2008 to 2018. An earlier resource list developed by Research Connections also examined father engagement in ECPs from 1999 to 2008. Resources in this list are grouped under the following categories:
1)	Literature reviews and syntheses on father engagement in ECPs
2)	Studies on father engagement in ECPs
3)	Interventions to engage fathers in ECPs

title: Bicycling Injuries in Children: The Role of the Built Environment
Creators: name: Aucoin, Janet
Publisher: name: Graduate Studies
Year: 2024
Subjects: subject: Epidemiology

description: Background: Bicycling has many health benefits for children but can result in injuries, some severe. Additionally, children’s perceptions of injury risk decrease participation. The built environment is associated with the risk of bicycling injury in adults, yet less is known about risks for children who have different bicycling behaviours and locations than adults. This dissertation improves understanding of child bicyclist injury risk factors and perceptions in Canada, with an emphasis on the role of the built environment. Methods: We recruited 333 injured child bicyclists (ages 5-17) who presented to pediatric emergency departments in Vancouver, Calgary, and Toronto from May 2018 - October 2021. Using data from participant interviews and in-person site audits of injury/control locations from the injured child’s route, Chapter 3 used a case-crossover study design to examine associations between built environment characteristics and child bicyclist injuries. Chapter 4 used data from the case-crossover study to explore injury circumstances and examine risk factors associated with severe child bicyclist injuries. In 2021, 40 participants also completed a qualitative interview to explore injured child bicyclists’ perceptions of risk factors and safety (Chapter 5). Results: The results in Chapter 3 provided evidence that unpaved off road locations, presence of debris, poor surface quality, surface grade, and construction were risk factors for child bicyclist injuries. In Chapter 4, motor vehicle involvement and intersections were associated with higher odds of severe injury in child bicyclists. In Chapter 5, child bicyclists shared that some of the factors that contribute to perceptions of safety included sharing spaces with motor vehicles, road design, debris, surface quality, and surface grade. Conclusions: This study adds to evidence suggesting built environment supports are important for increasing bicycling safety for Canadian children. There is a critical need to provide child bicyclists with safe spaces where they are physically separated from motor vehicles and to ensure that routes used by child bicyclists are properly maintained.
Leveraging eigenvalue veering for improved sensing with microelectromechanical systems

description: Energy localization in nearly periodic microsystems can be leveraged to create a new sensing paradigm that is orders of magnitude more sensitive than current resonant-frequency based systems. In this thesis, the theory which supports this claim is independently developed from a mathematical description of a two degree-of-freedom resonant system. A novel proof-of-concept microelectromechanical system (MEMS) was also designed and fabricated to support the theoretical claims. The system employed a unique resonator design with two different approaches to inducing asymmetry in the system which in turn leads to the localization of energy in one of the resonators. The system proved the resonant frequency dependence on disorder in the system and also showed that the eigenvector sensitivity to disorder was at least an order of magnitude greater than the frequency sensitivity. However, the eigenvector sensitivity could not be matched with theory. This was likely due to the time-varying nature of the coupling spring stiffness (up to a 300% change in magnitude). The coupling spring stiffness was time-varying due to the inverse cubic relationship to coupling gap distance. The gap distance changes with time since it is practically impossible to excite only the common mode, leading to a superposition with the anti-phase mode. This was partially due to the input signal displaying non harmonic tendencies. At the same time, energy localization in the system leads to different amplitudes of vibration for each resonator which will also lead to gap distance modulation. A three degree-of-freedom system was also examined theoretically with different approaches to stiffness perturbation and the resultant sensitivity expressions which can be leveraged for improved sensors were developed. The analysis shows that three degree-of-freedom systems can yield a 250% improvement over two degree-of-freedom systems which themselves are practically able to provide three to four order of magnitude improvements in sensitivity over resonant-frequency based sensors of the same size. The tools and insight needed to design for higher degree-of-freedom system are also provided in the form of the eigen-derivatives approach to calculating eigenvalue and eigenvector sensitivity to disorder in a symmetric system.

description: Recent advancements in deep learning have equipped healthcare professionals with valuable tools to support clinical decision-making and reduce workloads. However, many medical centers lack sufficient datasets to train deep learning models, especially for rare diseases or centers in remote or underserved areas. Although collecting and curating datasets from multiple centers into a centralized repository is commonly employed to solve this problem, this approach is often infeasible due to its costs and privacy regulations that prohibit data sharing. Consequently, many centers and populations will not benefit from cutting-edge artificial intelligence. The distributed deep learning framework proposed in this work addresses these challenges by training accurate models while patient data remains securely stored within its center. Thus, privacy concerns are addressed while collaborative multi-center training is facilitated. A key innovation of this work is the development and evaluation of the travelling model, a method well-suited for scenarios where individual centers have very limited data availability. The travelling model is evaluated across various scenarios, including extreme cases where centers contribute only a single medical image, and is applied to critical medical imaging tasks such as brain age prediction, disease classification, and tumour segmentation. In general, the travelling model effectively increases the overall dataset quantity and diversity without compromising patient data privacy. However, solutions for the inherent acquisition shift biases caused by variations in equipment and protocols across centers and decentralized data quality control are needed to leverage its full potential. Therefore, this work also developed and integrated two novel methods into the travelling model approach, a data harmonization for reducing acquisition shift biases and automated decentralized data quality control. The results of this work demonstrate that the travelling model framework achieved performances comparable to models trained on a centralized repository across all evaluated tasks. Moreover, it performed better than the commonly used federated learning in cases where centers contributed fewer than five datasets. Additionally, the proposed data harmonization method reduced scanner variability by 23%, improving disease classification accuracy by 4%. Finally, the automated decentralized quality control method effectively identified incorrect and low-quality datasets, enabling more robust and reliable model performance.
