description: Large artificial intelligence (AI) models exhibit remarkable capabilities in various application scenarios, but deploying them at the network edge poses significant challenges due to issues such as data privacy, computational resources, and latency. In this paper, we explore federated fine-tuning and collaborative reasoning techniques to facilitate the implementation of large AI models in resource-constrained wireless networks. Firstly, promising applications of large AI models within specific domains are discussed. Subsequently, federated fine-tuning methods are proposed to adapt large AI models to specific tasks or environments at the network edge, effectively addressing the challenges associated with communication overhead and enhancing communication efficiency. These methodologies follow clustered, hierarchical, and asynchronous paradigms to effectively tackle privacy issues and eliminate data silos. Furthermore, to enhance operational efficiency and reduce latency, efficient frameworks for model collaborative reasoning are developed, which include decentralized horizontal collaboration, cloud-edge-end vertical collaboration, and multi-access collaboration. Next, simulation results demonstrate the effectiveness of our proposed methods in reducing the fine-tuning loss of large AI models across various downstream tasks. Finally, several open challenges and research opportunities are outlined.

description: When designing a product that needs to fit the human shape, designers often use a small set of 3D models, called design models, either in physical or digital form, as representative shapes to cover the shape variabilities of the population for which the products are designed. Until recently, the process of creating these models has been an art involving manual interaction and empirical guesswork. The availability of the 3D anthropometric databases provides an opportunity to create design models optimally. In this paper, we propose a novel way to use 3D anthropometric databases to generate design models that represent a given population for design applications such as the sizing of garments and gear. We generate the representative shapes by solving a covering problem in a parameter space. Well-known techniques in computational geometry are used to solve this problem. We demonstrate the method using examples in designing glasses and helmets.

description: Can plants help to improve the air quality? People have often complained about Ivy on buildings, but research by Helix Pflanzen GmbH, a company that is specialised in the cultivation of ivy species and the development of green wall technology, is shedding new light on an old problem. Using a cultivated variety of ivy (Hedera helix ‘Wörner’), experiments were carried out that illustrated the binding effect that this Ivy has on fine dust particles. This is particularly important in urban areas, where fine dust can lead to significant impacts on quality of life.

Crystallographic investigation and characterization of the interaction between presynaptic voltage-gated calcium channels and snare proteins
Creators: name: Liu, Xiaohu
Publisher: name: University of British Columbia
Year: 2010

description: Voltage-gated calcium channels (Cay) have functions ranging from regulating release of hormones and neurotransmitters, generating cardiac action potentials, and excitation-contraction coupling. At nerve terminals, N- and P/Q- type Cavs convert the action potential into aC²⁺ signal that in turn triggers neurotransmitter release. Neurotransmitter release requires several components, such as SNARE proteins. SNAREs, as well as many other presynaptic proteins, can interact with Cavs and inhibit them by increasing their inactivation. The interaction is localized in the intracellular loop between domains II and III of the CL 1 subunit, in a domain termed ‘synprint’ (synaptic protein interaction site). In this study, we tried to solve the structure of the synprint site by crystallography. To date, long needle-shape crystals were obtained; however, the quality of these crystals was not good enough for X-ray diffraction. in addition, isothermal titration calorimetry (ITC) was used to determine the interaction between SNARE protein syntaxinlA and the synprint site. It turned out that not any binding was detected, suggesting that the interaction between SNARE proteins and the presynaptic Cas, if at all present, is weak.
Epidemiology and Outcomes of Alcoholic Hepatitis in Calgary: A Population-based Study
Creators: name: Pang, Jack X.Q.
Publisher: name: Graduate Studies
Year: 2014
Subjects: Epidemiology

description: Alcoholic hepatitis (AH) is an acute hepatic inflammatory disorder associated with excessive alcohol consumption. Without treatment, mortality rates of up to 50% have been reported in severe cases. Population-based studies on the epidemiology of AH are limited, and partially hindered by the lack of a validated algorithm to identify cases using administrative data. This study validated the coding of AH in the Discharge Abstract Database (DAD) for the Calgary region based on a review of medical records. We found the accuracy of coding for AH in this administrative database to be sub-optimal, with a positive predictive value (PPV) of 54%. Our data do not support the use of administrative data for large-scale epidemiological studies of AH. We also identified risk factors and assessed well-known prognostic models for 90-day mortality in a well-defined Canadian cohort of patients hospitalized for AH.

description: Understanding fractions is a method of finding the area or volume of a square by doing operations. In the circle of the proportion, the side of the square or the radius or diameter of the ball is found. The method of introducing the concept of fractions is important for teaching the operations of addition and subtraction in mathematics. This method is very useful for young students who want to understand and practice the ratio.
Dependency Detection and Migration in Software Systems and Libraries

description: Software systems must change over time or risk becoming obsolete, but direct changes can impact dependent functionality. Software developers perform change impact analysis and redress using automated tools to identify dependency relationships affected by change, and to recommend adaptations. However, these tools are restricted in their application: dependency analysis tools are language-specific but many systems are implemented using multiple languages, while recommenders are poor at identifying adaptations for change impacts from external libraries. This work proposes using semi-automated approaches for supporting change impact analysis and redress, in which the developer is relied upon to provide key details of dependency syntax or examples of correct adaptations. From such information, tool support can be generated that is appropriately configured for the developer’s software, and that can be further refined by the developer through additional details or examples until it is sufficiently accurate for their needs. Four studies validate this thesis. The first involves the semi-automated DSKETCH tool for polylingual dependency analysis, which requires developers to detail only key syntax using a simplified notation; it then uses this syntax to identify where potential dependencies exist. Developers were able to successfully configure and use DSKETCH on polylingual systems with only a short period of training. The second study examines how software libraries and their application programming interfaces (APIs) evolve over successive versions. The study found that existing recommenders are generally unsuccessful, and that most observed changes could not be automatically migrated. The third study introduces the UMAMI tool that detects correspondences between the syntactic structure of the old API functionality and possible replacements in the new library version to recommend adaptations for API changes. The fourth study examines how change recommenders could be hybridized in a flexible fashion, by relying on developer-provided examples of correct redress of API changes to tailor recommendations to a library’s particular characteristics.

Year: 2014
Subjects: Engineering--Electronics and Electrical

description: A simplified multi-step optimization approach for the correction of violating transmission voltages is developed and analyzed in this thesis. The contribution of this thesis are two fold. A receding horizon multi-step optimization (RHMSO) controller which utilizes a linearized system model is developed. This linear system model is derived from the non-linear steady state power flow equations based on sensitivity analysis. A comparison is made with single step optimization based on Model Predictive Control (MPC) to test the performance of the proposed multi step approach. Results show significant reduction in load shedding with a smoother system response. In addition, the concept of bias based error correction is introduced in the linear system model mentioned above. A comparison is made between the bias and non-bias based controllers. The results show that the bias based RHMSO with linear system model provides decrease in settling time and significant reduction in load curtailment, thus achieving better system performance.

Season-specific survival and growth rates of coastal cutthroat trout across a gradient of stream sizes in southwestern British Columbia
Creators: name: Sheldon, Kim Antoinette
Publisher: name: University of British Columbia
Year: 2010

description: To have greater predictive abilities for informed resource management guidelines for freshwater species protection and management, we need to increase our limited knowledge of the many aquatic species that inhabit small coastal streams. Coastal cutthroat trout (Oncorhynchus clarkii clarkii) are common to small streams in the Pacific Northwest and are a species of concern or threatened throughout their native range. To address knowledge needs I (1) examined the seasonal variation in survival rates of coastal cutthroat trout across a size gradient of smaller streams in coastal BC; and (2) contrasted 10th year post-harvest seasonal trout body condition and relative abundances, and thermal and physical habitats with pre-harvest and 4th year post-harvest values in small streams. The survival study used a robust mark-recapture design stratified seasonally to estimate monthly survival rates; and the streamside harvest study used a multi-year, replicated, before-after-control-impact design. Within the size range of smaller streams studied (n = 7), availability of aquatic habitat (i.e., residual depth) at low-flows was the best predictor of monthly survival rates (p = 0.011), supporting my hypothesis that greater availability of habitat confers higher survival in trout. In addition, a fitted curve suggested an asymptotic relation between water depth and survival rates; where beyond 25 cm of water, greater depth did not confer greater benefits to trout survival. Survival estimates also showed that the summer season had the lowest monthly survival rates across all streams in our study area. Post-harvest effects were not detected in trout relative abundances in the 10th year; however body condition had significantly (p < 0.001) increased in both the control and treatment streams compared to previous periods. During 2008-2009 treatment streams had comparatively higher water temperatures (0.8 – 1.5°C) than control streams. Given the cooler conditions of shaded streams in our coastal mountain region (e.g., 8-10°C); the modest warming of treatment streams may have conferred a benefit to trout growth and condition.

description: Osteoarthritis (OA) is a complex disease affecting articular cartilage and joint tissues. Macrophages in OA synovium contribute to the inflamed joint environment by releasing inflammatory mediators promoting cartilage loss. What remains unknown is how macrophages interact with synovial mesenchymal progenitor cells (sMPCs) in the joint. sMPCs are able to differentiate into cartilage but for unknown reasons, sMPC chondrogenic capacity is lost in OA. This thesis elucidates the relationship between macrophages and sMPC using synovial explants obtained from OA and normal patients. I found that altered macrophage activity (through cytokine stimulation and/or macrophage depletion) differentially regulates the chondrogenic capacity of sMPCs in a patient-specific manner. Also, the secretory profile of the explant is different between normal and OA patients in response to treatment. Taken together, there is heterogeneity within the responses of the OA patients, highlighting the need for personalized approaches to repair the cartilage within the OA joint.

description: The technique of Weinberg's spectral-function sum rule is a powerful tool for a study of models in which global symmetry is dynamically broken. It enables us to convert information on the short-distance behavior of a theory to relations among physical quantities which appear in the low-energy picture of the theory. We apply such technique to general supersymmetry breaking models to derive new sum rules.

description: We investigated the magnetoresistance and the Hall effect in an organic massless Dirac fermion system $α$-(BETS)$_2$I$_3$ under pressure. The Fermi energy of this system is slightly far away from the Dirac points, and thus the $ν=1$ quantum Hall state is realized in a low magnetic field at low temperatures. Moreover, the experimental formula for chemical potential as a function of temperature is clarified. We succeeded in detecting the inter-band effects of the magnetic field on the Hall conductivity when the chemical potential passes the Dirac points.

The Transformation of Landfills to Green Spaces: Identifying the Barriers and Benefits in the Greater Toronto Area (GTA)

subject: Redevelopment

description: In Canada, policy makers and planners have been paying significantly more attention to developing and improving the quality of life in urban areas. One issue that has been gaining momentum is the cleanup and redevelopment of urban landfills. As urban sprawl continues to grow, neighborhoods and communities are slowly reaching the boundaries of these once ‘rural’ landfills, and are creating a variety of social and environmental concerns. There has been a growing recognition among community groups and environmental organizations that landfills hold enormous potential for ‘greening’ city environments. Green space development has been emphasized throughout this study as a realistic and beneficial redevelopment opportunity. Instead of leaving a landfill site derelict and underutilized with no economic value, cities and municipalities have the opportunity to redevelop a site and create a community asset. This objective of this study is to identify and examine the barriers and benefits to transforming landfills to green spaces in the Greater Toronto Area (GTA). The identification of these barriers was derived from three distinct research strategies: a literature review, three case studies, and sixteen professional interviews. The data for this thesis derived from the sixteen interviews, based on their responses in filling out a ‘barrier matrix’. The GTA has achieved considerable success in converting landfills to green spaces largely due to government’s commitment, various financial incentives, effective public-private partnerships, and a growing demand for urban green spaces.

description: Work Package 2 (WP2) of the TURAS (Transitioning towards Urban Resilience and Sustainability) FP7 European Research and Knowledge Exchange Programme provides a unique and comprehensive reference for those interested in current understanding in relation to the benefits that green infrastructure can bring to cities in terms of increasing sustainability and resilience. To contextualise current understanding, it is necessary to understand the historical context of urban development. Architecture and planning theories since Le Corbusier’ Ville Radieuse axiom, almost one century ago, theorised and advised that green space should be one of the basic components of human urban settlements. Nevertheless, due to numerous constraints and the prioritisation of economic and social drivers for urbanisation, the key foci leading the development of European cities have been those for which green space was not always an intrinsic consideration or, if it was considered, was restricted in scope and functionality. Work package 2 activity units are showcases of work carried out under work package 2 that will be carried forward into the dissemination phase of TURAS through a series of workshops to help Public Authorities transition towards more sustainable and resilient communities. Workshops will be designed to benefit all stakeholders in the urban planning process. Activity Units from WP2 will showcase: how urban green infrastructure can be embedded at the heart of sustainable urban design; best practice for cost/benefit analysis of green infrastructure projects; how decision-making tools can support the design and planning process for urban green infrastructure; how biodiversity can benefit from design incorporating biomimicry of regional context; how green infrastructure can be embedded into planning guidance; how to design urban green infrastructure to create multifunctional ecosystem service benefits; good practice for the entire process of urban green infrastructure implementation from idea through to installation and management.

Gamma-Radiometric Study Of Thermal Decomposition
Creators: name: Oldham, Simon C.
Publisher: name: London South Bank University
Year: 1990

description: An investigation into using the absorption of gamma-radiation as a non-destructive analysis method for the study of thermally decomposing woods and polymers. A comparison of the decomposition characteristics of flame retarded materials has also been undertaken. A narrow, collimated beam of '137’Cs gamma-rays are passed through 50 mm cubes of wood or polymer, perpendicular to one-dimensional heat flow from a bank of well characterised infra-red heaters. The resultant gamma-rays are analysed, and the thermal degradation is indicated by the decrease in absorption of the sample as it decomposes. Moving the sample relative to the y-ray beam allows local densities to be determined throughout the bulk of the material. Simultaneously, temperatures are measured at various points within the samples, and these are used in conjunction with the absorption data to describe the overall decomposition with a first order kinetic model. This allowed the calculation of activation energy E, and pre-exponential factor A. Further abstract available on PDF.

description: We present a detailed imaging and spectral analysis of the merging environment of the bimodal cluster A3395 using X-ray and radio observations. X-ray images of the cluster show five main constituents of diffuse emission : A3395 NE, A3395 SW, A3395 NW, A3395 W, and a filament connecting NE to W. X-ray surface-brightness profiles of the cluster did not show any shock fronts in the cluster. Temperature and entropy maps show high temperature and high entropy regions in the W, the NW, the filament and between the NE and SW subclusters. The NE, SW and W components have X-ray bolometric luminosities similar to those of rich clusters of galaxies but have relatively higher temperatures. Similarly, the NW component has X-ray bolometric luminosity similar to that of isolated groups but with much higher temperature. It is, therefore, possible that all the components of the cluster have been heated by the ongoing mergers. The NE subcluster is the most massive and luminous constituent and other subclusters are found to be gravitationally bound to it. The W component is most probably either a clump of gas stripped off the SW due to ram pressure or a separate subcluster that has merged or is merging with the SW. No X-ray cavities are seen associated with the Wide Angle Tailed (WAT) radio source near the centre of the SW subcluster. Minimum energy pressure in the radio emission-peaks of the WAT galaxy is comparable with the external thermal pressure. The radio spectrum of the WAT suggests a spectral age of ~10Myr.

description: Semisort is a fundamental algorithmic primitive widely used in the design and analysis of efficient parallel algorithms. It takes input as an array of records and a function extracting a \emph{key} per record, and reorders them so that records with equal keys are contiguous. Since many applications only require collecting equal values, but not fully sorting the input, semisort is broadly applicable, e.g., in string algorithms, graph analytics, and geometry processing, among many other domains. However, despite dozens of recent papers that use semisort in their theoretical analysis and the existence of an asymptotically optimal parallel semisort algorithm, most implementations of these parallel algorithms choose to implement semisort by using comparison or integer sorting in practice, due to potential performance issues in existing semisort implementations. In this paper, we revisit the semisort problem, with the goal of achieving a high-performance parallel semisort implementation with a flexible interface. Our approach can easily extend to two related problems, \emph{histogram} and \emph{collect-reduce}. Our algorithms achieve strong speedups in practice, and importantly, outperform state-of-the-art parallel sorting and semisorting methods for almost all settings we tested, with varying input sizes, distribution, and key types. We also test two important applications with real-world data, and show that our algorithms improve the performance over existing approaches. We believe that many other parallel algorithm implementations can be accelerated using our results.

description: The noise in optical source needs to be characterized for the security of continuous-variable quantum key distribution (CVQKD). Two feasible schemes, based on either active optical switch or passive beamsplitter are proposed to monitor the variance of source noise, through which, Eve's knowledge can be properly estimated. We derive the security bounds for both schemes against collective attacks in the asymptotic case, and find that the passive scheme performs better.

description: The spin-orbital entangled states are of great interest as they hold exotic phases and intriguing properties. Here we use first-principles calculations to investigate the electronic and magnetic properties of RuI$_{3}$ and RuCl$_{3}$ in both bulk and monolayer cases. Our results show that RuI$_{3}$ bulk is a paramagnetic metal, which is in agreement with recent experiments. We find that the Ru$^{3+}$ ion of RuI$_{3}$ is in the spin-orbital entangled $j_{\rm eff}=\frac{1}{2}$ state. More interestingly, a metal-insulator transition occurs from RuI$_{3}$ bulk to monolayer, and this is mainly due to the band narrowing with the decreasing lattice dimensionality and to the Ru-I hybridization altered by the I $5p$ spin-orbit coupling. In contrast, RuCl$_{3}$ bulk and monolayer both show Mott-insulating behavior, the Ru$^{3+}$ ion is in the formal $S=\frac{1}{2}$ and $L=1$ state with a large in-plane orbital moment, and this result well explains the experimental large effective magnetic moment of RuCl$_{3}$ and the strong in-plane magnetization. The present work demonstrates the contrasting spin-orbital states and the varying properties of RuI$_{3}$ and RuCl$_{3}$.

description: We describe a new kludge scheme to model the dynamics of generic extreme-mass-ratio inspirals (EMRIs; stellar compact objects spiraling into a spinning supermassive black hole) and their gravitational-wave emission. The Chimera scheme is a hybrid method that combines tools from different approximation techniques in General Relativity: (i) A multipolar, post-Minkowskian expansion for the far-zone metric perturbation (the gravitational waveforms) and for the local prescription of the self-force; (ii) a post-Newtonian expansion for the computation of the multipole moments in terms of the trajectories; and (iii) a BH perturbation theory expansion when treating the trajectories as a sequence of self-adjusting Kerr geodesics. The EMRI trajectory is made out of Kerr geodesic fragments joined via the method of osculating elements as dictated by the multipolar post-Minkowskian radiation-reaction prescription. We implemented the proper coordinate mapping between Boyer-Lindquist coordinates, associated with the Kerr geodesics, and harmonic coordinates, associated with the multipolar post-Minkowskian decomposition. The Chimera scheme is thus a combination of approximations that can be used to model generic inspirals of systems with extreme to intermediate mass ratios, and hence, it can provide valuable information for future space-based gravitational-wave observatories, like LISA, and even for advanced ground detectors. The local character in time of our multipolar post-Minkowskian self-force makes this scheme amenable to study the possible appearance of transient resonances in generic inspirals.

description: Moral distress is a human experience arising when an individual knows what is ethically appropriate but is unable to carry out that action due to institutional constraints. It affects healthcare professions when there is a psychological disequilibrium and can lead to burnout. In this research, descriptive phenomenology was used to investigate whether pediatric subspecialty residents experience moral distress. The results indicate that they do experience moral distress for reasons including issues regarding futile treatment, barriers that prevent effective communication, inadequate resources and strenuous relationships with parents of patients. Residents in this study cope with moral distress by talking with colleagues or senior staff members about the difficult situations they encountered. Recommendations from this research include the introduction of regular rounds sessions to deal with difficult cases and regular orientations on support services available to medical subspecialty residents.

description: Atomically-thin molybdenum disulfide is emerging as a new nanomaterial with potential applications in the fields of electronic and photonics. Charge carrier dynamics plays an essential role in determining its electronic and optical properties. We report spatially and temporally resolved pump-probe studies of charge carriers in atomically-thin molybdenum disulfide samples fabricated by mechanical exfoliation. Carriers are injected by interband absorption of a 390-nm pump pulse and detected by measuring differential reflection of a time-delayed and spatially-scanned probe pulse that is tuned to an exciton transition. Several parameters on charge carrier dynamics are deduced, including carrier lifetime, diffusion coefficient, diffusion length, and mobility.

The differential expression of miRNAs in breast cancer cell-lines upon autophagy induction
Creators: name: Armstrong, Luke Jeffery
Publisher: name: University of British Columbia

description: Autophagy is a catabolic process of self-digestion that occurs at basal levels in all cells, degrading old and damaged components such as proteins and organelles. Autophagy is upregulated in response to cellular stress, including the types imposed on cancer cells, and its role in these circumstances is often to facilitate cell survival. However, the molecular mechanisms regulating autophagy in response to cellular stress are still not well understood. Other components of the cell that are regulated in response to cellular stress are small non-coding portions of RNA termed microRNAs (miRNAs) that act to control protein levels in the cell by degrading mRNA targets or repressing their translation. The overall objective of this research was to identify candidate miRNA regulators of autophagy. My hypothesis was that miRNAs that regulate autophagy will demonstrate differential expression in response to cell stresses that induce autophagy. To test this hypothesis, I conducted miRNA expression profiling by Illumina sequencing in untreated BT-474 breast cancer cells and in BT-474 cells treated with a high dose of tamoxifen, a known inducer of autophagy. 113 distinct miRNAs were found to be significantly differentially expressed (p<0.05 and >1.5 fold) between the tamoxifen treated sample and control, and the differential expression of a subset of these miRNAs was validated using QRT-PCR. Using the online miRNA resource, TargetScan, 27 of the differentially expressed miRNAs were found to have potential autophagy-related targets, and of these, seven were selected to undergo further expression analysis in two additional breast cancer cell-lines using an additional autophagy inducing treatment, nutrient deprivation. Four of the selected miRNAs demonstrated similar patterns of differential expression in all three breast cancer cell-lines under the two different autophagy-inducing conditions. These four miRNAs consistently showed decreased expression when autophagy was induced, and have the potential to be direct regulators of the autophagy pathway upon cell stress induction in breast cancer cells. Understanding the mechanisms underlying the regulation of stress-induced autophagy may provide insight into the role autophagy plays in breast cancer and reveal potential targets to alter the process for clinical benefit.

description: Increasing global demand for energy and declining fossil fuel resources continue to make coal deposits a primary source of energy. However, the process of converting coal into valuable syngas through surface gasification requires conventional mining, extraction, transportation, storage, surface processing, ash and environmental handling. Moreover, most coal deposits are located at great depth and have thin coal seams, making them either un-mineable or uneconomical using current technologies. Underground coal gasification (UCG) is an exciting alternative technique for producing syngas from coal conversion in-situ. This will eliminate the need for conventional mining and some surface facilities, increase safety, and lower capital expenditures. It is imperative that we develop accurate UCG models and simulations capable of incorporating the impacts of multi-disciplinary phenomena, in particular in the UCG process where there is no direct access to the developed underground reactors. Small-scale models can be used to investigate the mechanisms and details of the various phenomena taking place during UCG. Most of the models in the literature apply the CFD (computational fluid dynamics) approach to predict the experimental results or explore the effects of the operational parameters on the process at lower pressures. However, the CFD models include more details, such as multi-component diffusion of the gas components and turbulent flow. Applying these models to field scale simulations can be very expensive. The similarities between UCG and heavy oil in-situ combustion make it possible to use a thermal compositional hydrocarbon simulator to simulate the UCG process. Complex geology, various well configurations, and multi-phase flow can be efficiently simulated using models developed in the oil and gas industry. This study focuses on the adaptation of a commercial hydrocarbon simulator to model UCG processes at great depth by using applied techniques to convert the coal per gasification module. It presents assumptions and procedures to evaluate the required properties and kinetics of chemical reactions. Small-scale models are used to validate the proposed methods both quantitatively and qualitatively. In addition, large-scale numerical simulation models are used to compare the performance of different technologies. The Thulin test is modeled using a cross-sectional domain. We also explore issues and possible solutions associated with UCG modeling in tight coal seams.
