description: The Fisher information matrix of the cosmic microwave background (CMB) radiation power spectrum coefficients is a fundamental quantity that specifies the information content of a CMB experiment. In the most general case, its exact calculation scales with the third power of the number of data points N and is therefore computationally prohibitive for state-of-the-art surveys. Applicable to a very large class of CMB experiments without special symmetries, we show how to compute the Fisher matrix in only O(N^2 log N) operations as long as the inverse noise covariance matrix can be applied to a data vector in time O(l_max^3 log l_max). This assumption is true to a good approximation for all CMB data sets taken so far. The method takes into account common systematics such as arbitrary sky coverage and realistic noise correlations. As a consequence, optimal quadratic power spectrum estimation also becomes feasible in O(N^2 log N) operations for this large group of experiments. We discuss the relevance of our findings to other areas of cosmology where optimal power spectrum estimation plays a role.

description: We look at observational constraints on the thawing class of scalar field models proposed to explain the late time acceleration of the universe. Using the recently introduced `Statefinder Hierarchy', we compare these thawing class of models with other widely studied dark energy (and modified gravity) models to check the underlying parameter degeneracies. We put constraints on the deviations of these thawing models from the canonical ΛCDM model using a large class of observational data, e.g, the Supernova Type Ia data, the BAO data, the CMB data and data from the measurements of the Hubble parameter using red-envelope galaxies. We also forecast constraints using a simulated dataset for the future JDEM SNe survey. Our study shows that, although with current data it is difficult to distinguish different thawing models from ΛCDM, a future JDEM like mission would be able tell apart thawing models from ΛCDM for currently acceptable values of Ω_{m0}

Supersymmetric minimal B-L model at the TeV scale with right-handed Majorana neutrino dark matter

description: We propose a supersymmetric extension of the minimal $B-L$ model where we consider a new $Z_2$-parity under which one right-handed neutrino is assigned odd parity. When the Majorana Yukawa coupling of a $Z_2$-even right-handed neutrino is large, radiative corrections will drive the mass squared of the corresponding right-handed sneutrino to negative values, breaking the $B-L$ gauge symmetry at the TeV scale in a natural way. Additionally, R-parity is broken and thus the conventional supersymmetric dark matter candidate, the neutralino, is no longer viable. Thanks to the $Z_2$-parity, the $Z_2$-odd right-handed neutrino remains a stable dark matter candidate even in the presence of R-parity violation. We demonstrate that the dark matter relic abundance with an enhanced annihilation cross section by the $B-L$ gauge boson (Z') resonance is in accord with the current observations. Therefore, it follows that the mass of this dark matter particle is close to half of the Z' boson mass. If the Z' boson is discovered at the Large Hadron Collider, it will give rise to novel probes of dark matter: The observed Z' boson mass will delineate a narrow range of allowed dark matter mass. If the Z' boson decays to a pair of dark matter particles, a precise measurement of the invisible decay width can reveal the existence of the dark matter particle.

description: Automated manufacturing, driven by rising demands for mass-produced products, calls for efficient systems such as the peg-in-hole assembly. Traditional industrial robots perform these tasks but often fall short in speed during pick-and-place processes. This study presents an innovative mechatronic system for peg-in-hole assembly, integrating a novel peg insertion tool, assembly mechanism and control algorithm. This combination achieves peg insertion with a 200 µm tolerance without the need for pick-and-place, meeting the requirements for high precision and rapidity in modern manufacturing. Dual cameras and computer vision techniques, both traditional and machine learning (ML)-based, are employed to detect workpiece features essential for assembly. Traditional methods focus on image enhancement, edge detection and circular feature recognition, whereas ML verifies workpiece positions. This research also introduces a novel statistical quality inspection, offering an alternative to standard ML inspections. Through rigorous testing on varied workpiece surfaces, the robustness of the methods is affirmed. The assembly system demonstrates a 99.00% success rate, while the quality inspection method attains a 97.02% accuracy across diverse conditions, underscoring the potential of these techniques in automated assembly, defect detection and product quality assurance.

description: A generalization of the Weyl law to systems with a sharply divided mixed phase space is proposed. The ansatz is composed of the usual Weyl term which counts the number of states in regular islands and a term associated with sticky regions in phase space. For a piecewise linear map, we numerically check the validity of our hypothesis, and find good agreement not only for the case with a sharply divided phase space, but also for the case where tiny island chains surround the main regular island. For the latter case, a non-trivial power law exponent appears in the survival probability of classical escaping orbits, which may provide a clue to develop the Weyl law for more generic mixed systems.

description: Linear response spectra of a driven intrinsic localized mode in a micromechanical array are measured as it approaches two fundamentally different kinds of bifurcation points. A linear phase mode associated with this autoresonant state softens in frequency and its amplitude grows as the upper frequency bifurcation point is approached, similar to the soft mode kinetic transition for a single driven Duffing resonator. A lower frequency bifurcation point occurs when the four-wave-mixing partner of this same phase mode intercepts the top of the extended wave branch, initiating a second kinetic transition process.

description: Graphene, a 2D carbon-based material with exceptional characteristics, has proven its potential in various applications, branching into fields such as electronics, energy storage, sensors, and more. Various techniques have been developed to synthesize single and multi-layer graphene sheets. However, each method for utilizing graphene still presents a range of challenges, such as low yield, the use of toxic reagents, methods that are not scalable, time-consuming processes, and multi-step procedures. Among all these methods, electrochemical exfoliation is considered as a facile and environmentally friendly method which can prepare the doped and functionalized graphene with different elements, metals, metal oxides and polymers. In this work, we have modified the electrochemical exfoliation method and developed a novel procedure which can simultaneously produce doped and functionalized graphene with nitrogen, sulphur, phosphor, MnO2 and tannic acid. It was shown that the chemical structure of the graphene can easily be tuned for a specific application by utilizing different electrolytes. Additionally, the yield of this process has been increased by 78% by its combination with the liquid-phase exfoliation method, all without requiring any additional steps. Subsequently, as-synthesized composites have been investigated for energy storage in liquid and solid-state supercapacitors. We prepared the freestanding and flexible working electrodes by vacuum filtration of the graphene composites without the addition of any conductive additive and binder. It was shown that the pseudocapacitance behaviour of MnO2 can increase the capacitance of the graphene by 192% while showing 98.4% capacitance retention after 10,000 cycles. The obtained results suggest the great potential of the electrochemical exfoliation method for synthesizing graphene-based composites for application in energy storage devices.

description: Contemporary poetry that utilizes medieval poetic forms can alter how one views the monolith of history, as well as provide insight into our present moment. In particular, queer poetry that reimagines the Middle Ages sheds light on an archive seldom explored, which this collection aims to expand. My poetry manuscript, Can I Exist without Prefix?, uses sundry styles of medieval poetry, and invokes various texts and medievalism, to highlight queer presence in the past, and destabilize harmful and inaccurate misconceptions of the Middle Ages circulating in the present moment. The subsequent exegesis, “‘The past remains, therefore, and even returns’: the Quasi-Object in Queer Uses of Medieval Poetry” examines two poetry collections, feeld by Jos Charles and […] by Ava Hofmann, alongside Bruno Latour’s ideas around the quasi-object in We Have Never Been Modern and Elizabeth Freeman’s theory of temporal drag in Time Binds: Queer Temporalities, Queer History, to demonstrate how creative works in the genre destabilize contemporary conversations that view queerness as solely a construct of the present. Jos Charles’ feeld explores transgender identity through agriculture conceits, using a language that is a hybrid of Middle English and cyberspeak. Ava Hofmann’s […] reimagines Old English metrical charms through the creation of an archival manuscript, filled with erasure and lacunae, that documents her transgender experience. My poetry collection joins these works in showing that we are not as far away from the Middle Ages as we think, opening the conversation around, and highlighting the urgent next to explore, queer representation in both the past and present.

description: Isolated populations ultimately go extinct because of the intrinsic noise of elementary processes. In multi-population systems extinction of a population may occur via more than one route. We investigate this generic situation in a simple predator-prey (or infected-susceptible) model. The predator and prey populations may coexist for a long time but ultimately both go extinct. In the first extinction route the predators go extinct first, whereas the prey thrive for a long time and then also go extinct. In the second route the prey go extinct first causing a rapid extinction of the predators. Assuming large sub-population sizes in the coexistence state, we compare the probabilities of each of the two extinction routes and predict the most likely path of the sub-populations to extinction. We also suggest an effective three-state master equation for the probabilities to observe the coexistence state, the predator-free state and the empty state.

description: In numerous cities, population expansion and technological advancements necessitate proactive modernization and integration of technology. However, the existing bureaucratic structure often hinders local officials' efforts to effectively address and monitor residents' needs and enhance the city accordingly. Understanding what people find important and useful can be inferred from their posts on social media. Twitter, as one of the most popular social media platforms, provides us with valuable data that, with the right tools and analysis, can provide insights into the performance of urban services and residents' perception of them. In this study, we used the city of Calgary as an exemplar to gather tweets and analyze topics relating to city development, urban planning, and minorities. Natural language processing (NLP) techniques were used and developed to preprocess stored tweets, classify the emotions, and identify the topics present in the dataset to eventually provide a set of topics with the prevalent emotion in that topic. We utilized a variety of methods to analyze the collected data. BERTopic for topic modeling and few-shot learning using Setfit for emotion analysis outperformed the others. Hence, we identify issues related to city development, senior citizens, taxes, and unemployment using these methods, and we demonstrate how delving into these analyses can improve urban planning.
Municipal Wastewater Effluent and Stormwater impacts the acute stress-induced Metabolic Rate and Plasma Metabolome in Rainbow Trout

description: Municipal wastewater effluent (MWWE) and urban runoff (stormwater) are complex contaminant mixtures that have the potential to impact aquatic biota including fish. Stormwater consists of compounds such as herbicides, pesticides, nutrients, metals, hydrocarbons, and emerging contaminants that wash off surfaces within urban catchments and into aquatic environments, while MWWE often includes nutrients and pharmaceuticals that can be resistant to current treatment methods. Previous studies have identified obesogenic and reproductive effects on wild fish populations within the Bow River, however the influence of these effects on stress performance, swimming ability, and energy metabolism have received less attention. The objective of this thesis was to use a metabolomic approach to investigate whether metabolic costs associated with MWWE and stormwater exposure altered stress response, swimming ability, and metabolic rate of an economically important sportfish, rainbow trout (Oncorhynchus mykiss), in the Bow River as it flows through Calgary, Alberta. We hypothesized that metabolic costs for detoxification would reduce the ability of rainbow trout to cope with an acute secondary stressor (Chapter 2), and that these costs would also reduce swimming ability and energy availability during a strenuous swim performance test (Chapter 3). Our findings indicate that cortisol release following activation of the hypothalamus-pituitary-interrenal (HPI) axis by an acute 1-min air exposure stressor was maintained following in vivo MWWE and stormwater exposure. Plasma metabolomics analysis identified metabolic disruptions that were amplified during stress response resulting in a distinct plasma metabolome response after exposure to MWWE. Metabolite concentrations and activities of pyruvate kinase and lactate dehydrogenase suggest an increased glycolytic capacity and more reliance on anaerobic metabolism following MWWE and stormwater exposure. The maximum metabolic rate (MMR) measured during a ramp swim velocity test was reduced in fish exposed to MWWE and stormwater, and this contributed to a reduced metabolic scope in fish exposed to MWWE. Our results suggest that metabolic disruption caused by MWWE and stormwater reduces energy availability for energy demanding activities such as predator avoidance and migration.

description: During the challenging isolation of the COVID-19 pandemic, individuals turned to a multitude of creative activities. Educators noted that engaging in creativity positively affected post-secondary learners’ wellbeing and resiliency during lockdowns and our triaged turn to online learning. Drawing on my experience as an artist and art educator while learning from and thinking through Indigenous principles, this arts-based research sought to understand how creativity developmental activity might affect wellbeing and contribute to the aims of reconciliation. This art-making research program examined the immediate and diachronic influences of artifacts of creative activity on wellbeing of adult learners at any level of creative capacity. These knowledge-based insights drew from the experiences of the participants and myself in the creative process and revealed creativity as a meaningful innate human characteristic with profound growth potential. In sum, educators could use creativity and the artifacts of the activity as an educational intervention to bolster wellbeing and sustain all learners through difficult times and the challenging topics of transformative learning in adult education.

description: The optical Faraday effect describes the rotation of linear polarization upon propagation through a medium in the presence of a longitudinal magnetic field. The effect arises from a different phase delay between the right and left handed polarisation components of the light. In this paper we predict a Faraday effect for a completely different system: electron vortices. Free electron vortex states were recently observed in transmission electron microscopy experiments, and they introduce new degrees of freedom into the probing of matter with electron beams. We associate a rotation of a vortex superposition with the fact that different phases are acquired by oppositely handed vortices propagating in a magnetic field. We show that, in contrast to the optical Faraday effect, the rotation of the electron beam occurs in vacuum and arises from the intrinsic chirality of the constituent vortex states.

description: Upper Cretaceous tyrannosauroid material from North America was primarily known from upper Campanian through Maastrichtian formations until the recent discovery of derived tyrannosaurid taxa from lower-to-mid Campanian deposits in the southwestern United States. However, diagnostic material from contemporaneous deposits further north in Alberta (Canada) and Montana (USA) has yet to be documented. Here we report the discovery of a new tyrannosaurine tyrannosaurid from the mid- Campanian Foremost Formation of Alberta, Thanatotheristes degrootorum gen. et. sp. nov, which helps fill this gap. The new tyrannosaurine, diagnosed by five autapomorphies, is found to be the sister taxon to the late Campanian genus Daspletosaurus. Thanatotheristes is distinct from Daspletosaurus based on several features, and lacks at least two apomorphies of the latter taxon. Together, these taxa form the newly established Daspletosaurini, a clade of long-, deep-snouted tyrannosaurines endemic to northern Laramidia during the Campanian. Our study demonstrates that Tyrannosauridae is composed of several geographically-segregated clades rather than a series of monogeneric successive sister taxa as recovered by previous studies. The geographic segregation of tyrannosaurid clades within North America provides renewed evidence for provinciality among large theropods during the Late Cretaceous.

In a world where constant improvement of the sensitivity of a given method is driving diagnostic advancement, we developed azide and alkyne modified dendrimers that allow to establish sandwich-type detection assays that show significantly improved signal intensities and signal to noise ratios far beyond of what is currently possible.

description: Immigrant integration can be complicated by multiple factors like language, ethnicity, culture, and population size. While macro-level language-in-immigration policies continue to conceptualize these variables and immigrant integration as monolithic, micro-level integration practices of immigrants are often multidirectional, multidimensional, and multiplex. These practices are further complicated by the emergence of ethnic networks that continue to grow stronger, denser and agile, and often impact the ways immigrants settle and integrate in a host society. Although South Asians have emerged as the biggest ethnic minority in Alberta and have shown tendency towards co-ethnic integration, there is scarcity of research on how they use official and ethnic languages for settlement and integration in Alberta and the type of integration taking place within their ethnic networks. Filling this gap, this study reports findings from a critical analysis of Canada’ federal language-in-immigration policy about skilled immigrants and perceptions about language usage for integration of a sub-group of South Asians from Bangladesh, India, and Pakistan. In addition to reporting a disconnect between integration conception in policy (i.e., monolingual) and integration achievement in practice (complex, broader, and selective), the study calls for enacting meso-level policies that reflect macro-level policy goals and micro-level practices of diverse immigrant communities. The study has implications for immigrant settlement and integration policies, programs, services, and research.
Insights on Engaging Men and Boys in Creating a More Gender Equal Future in Canada

description: This article presents findings from a national qualitative research study of 33 diverse and profeminist leaders who identify as men and are engaged in gender equality work with men and boys across Canada. Key findings include the need to meet men where they are at, moving away from the ineffective “all men are perpetrators” frame, and to evolve to new and more relatable narratives and approaches that get men committed to this work for their own liberation. Taking an intersectional approach and working in partnership with feminist and intersectional organizations are essential to advancing gender equality in the Canadian context.
Contributions to the ultrastructural diversity and molecular phylogeny of phagotrophic euglenids and their episymbionts
Creators: name: Breglia, Susana Alicia
Publisher: name: University of British Columbia
Year: 2012

description: The Euglenida is a diverse group of single celled eukaryotes with modes of nutrition that include phagotrophy, osmotrophy, and phototrophy. Phototrophic members of the group have attracted the most attention from previous researchers, and some species (e.g., Euglena gracilis) have become models in cell biology research. Phagotrophic euglenids, by contrast, are difficult to cultivate and manipulate so are severely underrepresented in culture collections, comparative ultrastructural studies, and molecular phylogenetic studies. Species discovery and the comparative ultrastructure of phagotrophic euglenids within a phylogenetic context were the main aims of this thesis. These data are essential for a comprehensive knowledge of the overall diversity and evolutionary history of euglenids as a whole, as well as for a better understanding of the relationships with their closest euglenozoan relatives, the Kinetoplastida and the Diplonemida. I generated DNA sequences of heat shock protein 90 and small subunit (SSU) rRNA genes from several different species of phagotrophic euglenids in order to evaluate some of the deepest branches in the phylogeny of euglenozoans, especially the phylogenetic position of Petalomonas cantuscygni. This species has a set of morphological features that are intermediate between kinetoplastids and euglenids (e.g., pellicle strips and kinetoplast-like mitochondrial inclusions). I also characterized the ultrastructure, feeding behaviour, and phylogenetic position of Heteronema scaphurum, a phagotrophic euglenid that feeds on green algal prey and is equipped with a distinctive “cytoproct” or cell anus. My explorations in low oxygen marine sediments led me to discover and characterize a novel lineage of euglenozoans, the “Symbiontida”. Members of this group formed intimate symbiotic relationships with at least two distinct types of epibiotic bacteria: rod-shaped epsilon-proteobacteria and spherical-shaped verrucomicrobia. I was able to show, using electron microscopy, that the verrucomicrobial symbionts were capable of evasive sporulation using a conspicuous extrusive apparatus that consisted of a thread tightly wound around a central core of DNA. The highly similar episymbionts reported previously on a group of ciliates led to questions about host transfer and the convergent evolution of extrusive organelles across the tree of eukaryotes.

description: We calculate the baryon asymmetry produced at the electroweak phase transition by quasi-degenerate third generation sfermions in the minimal supersymmetric extension of the Standard Model. We evaluate constraints from Higgs searches, from collider searches for supersymmetric particles, and from null searches for the permanent electric dipole moment (EDM) of the electron, of the neutron and of atoms. We find that resonant sfermion sources can in principle provide a large enough baryon asymmetry in various corners of the sfermion parameter space, and we focus, in particular, on the case of large $\tanβ$, where third-generation down-type (s)fermions become relevant. We show that in the case of stop and sbottom sources, the viable parameter space is ruled out by constraints from the non-observation of the Mercury EDM. We introduce a new class of CP violating sources, quasi-degenerate staus, that escapes current EDM constraints while providing large enough net chiral currents to achieve successful "slepton-mediated" electroweak baryogenesis.

description: The 21st century’s challenges—climate change, growing population, resource decline, habitat and species loss—mean that current practices must be replaced, redesigned, and improved. Phytoplankton, reliant on water, light, nutrients, and CO2, offer versatile applications in nutritional supplements, agricultural feed, bioplastics, wastewater treatment, and bioenergy production. Currently, the most successful commercial ventures center on select taxa like Spirulina and Chlorella and produce high-value products for human consumption. Expanding the scope of viable commercial taxa and their applications hinges on overcoming critical challenges in cultivation, notably biomass productivity, robustness, and resource use. Inspiration can be drawn from natural environments where phytoplankton flourish, like alkaline soda lakes. These lakes are characterized by elevated pH and high carbonate alkalinity. Growing phytoplankton in high pH (10+), high carbonate alkalinity medium (0.5 M) increases the driving force for CO2 capture into solution and helps exclude competitors and predators which can cause biomass instability. This thesis chronicles the transition of biomass from alkaline soda lakes, dominated by the cyanobacterium Sodalinema alkaliphilum, from laboratory to large-scale outdoor demonstration. Chapter 2 explores the microbes inhabiting such lakes and their societal applications. Chapter 3 describes the design, construction, and operation of laboratory photobioreactors with programmable lighting and online growth measurements. Chapter 4 follows outdoor biomass cultivation in a 1,000 L photobioreactor, demonstrating sustained growth at a pH sufficient for CO2 capture from air. In Chapter 5, cultivation in a 3,000 L open raceway pond (ORP) reports long-term medium re-use, water requirements, and CO2 capture from air, although optimisation is necessary. Operational seasons ranged 70–140 days—160 being the maximum possible in Calgary’s temperate climate. Average daily yields were ∼ 3–4 g/m2/day (ash-free) with modeling predicting productivity could reach 6 g/m2/day by reducing biomass density. Finally, Chapter 6 quantifies ORP biomass losses, with stable isotope probing unveiling insights into S. alkaliphilum physiology and ecology. In conclusion, this research explores the feasibility of growing S. alkaliphilum biomass at scale for extended durations and has generated baseline data and operational insights which can be used to inform and refine the sustainability and productivity of future iterations of this technology.

description: Simultaneous Localization and Mapping (SLAM) is a decades-old problem. The classical solution to this problem utilizes entities such as feature points that cannot facilitate the interactions between a robot and its environment (e.g., grabbing objects). Recent advances in deep learning have paved the way to accurately detect objects in the image under various illumination conditions and occlusions. This led to the emergence of object-level solutions to the SLAM problem. Current object-level methods depend on an initial solution using classical approaches and assume that errors are Gaussian. This research develops a standalone solution to object-level SLAM that integrates the data from a monocular camera and an IMU (available in low-end devices) using Rao Blackwellized Particle Filter (RBPF). RBPF does not assume Gaussian distribution for the error; thus, it can handle a variety of scenarios (such as when a symmetrical object with pose ambiguities is encountered). The developed method utilizes shape instead of texture; therefore, texture-less objects can be incorporated into the solution. In the particle weighing process, a new method is developed that utilizes the Intersection over the Union (IoU) area of the observed and projected boundaries of the object that does not require point-to-point correspondence. Thus, it is not prone to false data correspondences. Landmark initialization is another important challenge for object-level SLAM. In the state-of-the-art delayed initialization, the trajectory estimation only relies on the motion model provided by IMU mechanization (during the initialization), leading to large errors. In this thesis, two novel undelayed initializations are developed. One relies only on a monocular camera and IMU, and the other utilizes an ultrasonic rangefinder as well. The developed object-level SLAM is tested using wheeled robots and handheld devices, and an error (in the position) of 4.1 to 13.1 cm (0.005 to 0.028 of the total path length) has been obtained through extensive experiments using only a single object. These experiments are conducted in different indoor environments under different conditions (e.g. illumination). Further, it is shown that undelayed initialization using an ultrasonic sensor can reduce the algorithm's runtime by half.

description: We present an experiment-based characterization of passive suppression and active self-interference cancellation mechanisms in full-duplex wireless communication systems. In particular, we consider passive suppression due to antenna separation at the same node, and active cancellation in analog and/or digital domain. First, we show that the average amount of cancellation increases for active cancellation techniques as the received self-interference power increases. Our characterization of the average cancellation as a function of the self-interference power allows us to show that for a constant signal-to-interference ratio at the receiver antenna (before any active cancellation is applied), the rate of a full-duplex link increases as the self-interference power increases. Second, we show that applying digital cancellation after analog cancellation can sometimes increase the self-interference, and thus digital cancellation is more effective when applied selectively based on measured suppression values. Third, we complete our study of the impact of self-interference cancellation mechanisms by characterizing the probability distribution of the self-interference channel before and after cancellation.

description: We study nearest neighbor random walks on fixed environments of $\mathbb{Z}$ composed of two point types : $(1/2,1/2)$ and $(p,1-p)$ for $p>1/2$. We show that for every environment with density of $p$ drifts bounded by $λ$ we have $\limsup_{n\rightarrow\infty}\frac{X_n}{n}\leq (2p-1)λ$, where $X_n$ is a random walk on the environment. In addition up to some integer effect the environment which gives the best speed is given by equally spaced drifts.
