description: We show that the classical fourth order accurate compact finite difference scheme with high order strong stability preserving time discretizations for convection diffusion problems satisfies a weak monotonicity property, which implies that a simple limiter can enforce the bound-preserving property without losing conservation and high order accuracy. Higher order accurate compact finite difference schemes satisfying the weak monotonicity will also be discussed.

Catching the Waves in the Sea of Noise: Squeezed Light in Advanced LIGO and Beyond
Creators: name: Kijbunchoo, Nutsinee
Publisher: name: The Australian National University
Year: 2022

description: In 2015, LIGO's first gravitational wave detection opened up a new window to the universe and marks the beginning of the gravitation-wave astronomy era. In 2017, the first binary neutron star coalescence with electromagnetic counterparts was detected and marked the beginning of multi-messenger astronomy. The advanced LIGO detector has become so sensitive that its performance is broadly limited by quantum noise -- the random behavior of photons that are dictated by the Heisenberg Uncertainty Principle called shot noise. Even though the idea of injecting squeezed light to help manipulate the quantum noise in LIGO was first proposed in 1981, it took nearly 4 decades before the squeezed light source was integrated as part of a normal operation in advanced LIGO. This thesis firstly highlights work done on the squeezed light source, sensing and control implementation at LIGO Hanford. The result is a robust system that runs 100% of the detector observation time and an improvement of ~3 dB in the detector sensitivity. With ~50% more of the universe volume covered scientists were able to detect new events such as a black hole-neutron star coalescence and a mysterious astronomical object that falls within the mass-gap region. The squeezed light source installed in advanced LIGO is frequency independent. Shot noise improvement at high frequency was achieved at an expense of quantum noise performance at low frequency, the radiation pressure noise. In 2020-2021, the aLIGO detector is being upgraded to an A+ detector with the goal of 6 dB squeezing. A 300-meter long filter cavity will be integrated as part of the squeezed light system to allow for frequency-dependent squeezing. This thesis secondly proposes an alternative sensing and control scheme for the squeezed light source that utilizes the filter cavity, resulting in a better phase noise performance as both phase noise and optical losses can degrade the amount of squeezing the detector can achieve. LIGO detectors were designed to be sensitive to the coalescence of black holes and neutron stars at the 100 Hz frequency range. However, important information on matter at extreme density can be found at the 1 kHz frequency range. A smaller scale detector such as the Neutron Star Extreme Matter Observatory (NEMO) has been proposed in order to cover more of the gravitational wave spectrum. This thesis thirdly discusses the idea of using a twin-signal-recycling interferometer technique combined with internal squeezing to enhance the performance of a kHz scale detector. The final part of this thesis demonstrates a table-top twin-signal-recyling interferometer with a newly designed sensing and control scheme that is compatible with the low noise requirement of the internal squeezing. The experiment marks the first step towards an internal squeezing inside a twin-signal-recycling interferometer experiment.

description: For solving two-dimensional incompressible flow in the vorticity form by the fourth-order compact finite difference scheme and explicit strong stability preserving (SSP) temporal discretizations, we show that the simple bound-preserving limiter in [Li H., Xie S., Zhang X., SIAM J. Numer. Anal., 56 (2018)]. can enforce the strict bounds of the vorticity, if the velocity field satisfies a discrete divergence free constraint. For reducing oscillations, a modified TVB limiter adapted from [Cockburn B., Shu CW., SIAM J. Numer. Anal., 31 (1994)] is constructed without affecting the bound-preserving property. This bound-preserving finite difference method can be used for any passive convection equation with a divergence free velocity field.
Age-Related Differences in Object-Similarity Judgment
Creators: McKnight, D E.
Publisher: name: University of Alberta Library
Year: 2022

As people age, they adjust how they associate objects. We examine the interplay between age and various aspects of object similarity. For this, we perform two experiments: one between adults aged 25–35 and 50–60 and another between six-year-olds and adults. Between 25–35- and 50–60-year-olds, we investigate discrepancies in preference for each of 49 object-comparison dimensions. Between six-year-olds and adults, we investigate changes in the prioritization of the classes of object-comparison relations known as taxonomic and thematic relations. To facilitate these tasks, we use a prior interpretable, machine-learned computational model; this model is trained to perform an odd-one-out-among-three task with a vector embedding for each object being compared.

For the first task, between 25–35-year-olds and 50–60-year-olds, we examine each of the 49 object-comparison dimensions defined by the prior interpretable model. These dimensions are human-interpretable, quantifying similarities such as “metallic” or “food-related.” We modify the architecture of that model to learn the preferences of each age group for each of those dimensions. We then compare those preferences between each age group.

For the second task, between six-year-olds and adults, we examine the classes of object-comparison relations described by taxonomic and thematic reasoning. We use the interpretable model to assign taxonomic and thematic scores to object-comparison questions, then select questions from amongst those to administer to six-year-olds. Finally, we contrast their responses with previous adult ones to elicit age-related changes in the prioritization of taxonomic and thematic reasoning, both in absolute terms and relative to one another.

In the context of prior literature, we provide measures of differences in object-similarity judgment between younger and older adults for each of 49 fine-grained types of object similarity and remark upon the resulting trends. We corroborate a thematic-to-taxonomic trend in thinking from adolescence to adulthood. Finally, we expand the knowledge-base of the common-resource THINGS initiative with our results.

description: An ongoing flood of comparative genomic data is identifying human lineage specific (HLS) sequences of unknown function, and there is strong interest in investigating their functional effects. Transgenic apes, our closest evolutionary relative, have the highest potential to express HLS sequences as they are expressed in Homo sapiens and likewise experience harm from such transgenic research. These harms render the conduct of this research ethically unacceptable in apes, justifying regulatory barriers between these species and all other non-human primates for transgenic research.

description: To resolve the nature of the hidden order below 17.5\,K in the heavy fermion compound URu$_2$Si$_2$, identifying which symmetries are broken below the hidden order transition is one of the most important steps. Several recent experiments on the electronic structure have shown that the Fermi surface in the hidden order phase is quite close to the result of band-structure calculations within the framework of itinerant electron picture assuming the antiferromagnetism. This provides strong evidence for the band folding along the c-axis with the ordering vector of $(0\,0\,1)$, corresponding to broken translational symmetry. In addition to this, there is growing evidence for fourfold rotational symmetry breaking in the hidden-order phase from measurements of the in-plane magnetic anisotropy and the effective mass anisotropy in the electronic structure, as well as the orthorhombic lattice distortion. This broken fourfold symmetry gives a stringent constraint that the symmetry of the hidden order parameter should belong to the degenerate $E$-type irreducible representation. We also discuss a possibility that time reversal symmetry is also broken, which further narrows down the order parameter that characterizes the hidden order.

description: Chromatin immunoprecipitation experiments followed by sequencing (ChIP-seq) detect protein-DNA binding events and chemical modifications of histone proteins. Challenges in the standard ChIP-seq protocol have motivated recent enhancements in this approach, such as reducing the number of cells required and increasing the resolution. Complementary experimental approaches – for example DNaseI hypersensitive site mapping and analysis of chromatin interactions mediated by particular proteins - provide additional information about DNA-binding proteins and their function. These data are now being used to identify variability in the functions of DNA-binding proteins across genomes and individuals. In this Review, I describe the latest advances in methods to detect and functionally characterize DNA-bound proteins.

Projected gradient descent methods for simultaneous-source seismic data processing
Creators: Lin, Rongzhi
Publisher: name: University of Alberta Library
Year: 2022

Simultaneous-source acquisition is a seismic data acquisition technology that has become quite popular in recent years due to its economic advantages. Contrary to the conventional seismic acquisition, where one records the seismic response of only one source at a time, in simultaneous source acquisition, an array of receivers record the response of more than one source. The latter leads to a saving in acquisition time, but it creates new problems in subsequent data processing stages where each seismic record must correspond to the response of one single source. The basic idea for simultaneous source data processing is to separate the sources and thereby estimate the responses one would have acquired via a conventional seismic data acquisition. Then one can adopt a traditional seismic workflow to process and invert the seismic data.

This thesis focuses on developing inversion schemes for separating simultaneous-source data. I pay particular attention to strategies based on the Projected Gradient Descent (PGD) method with a projection synthesized via robust denoising algorithms. First, I propose adopting a robust and sparse Radon transform to define a coherence pass projection operator to guarantee solutions that honour simultaneous source records. I show that a critical improvement in convergence is attainable when the coherence pass projection originates from a robust and sparse Radon transform. The latter is a consequence of having an iterative source separation algorithm that applies intense denoising to erratic blending noise in its initial iterations.

In addition, I also propose an inversion scheme for simultaneous-source data separation based on a robust low-rank approximation algorithm. A robust Multichannel Singular Spectrum Analysis (MSSA) filtering is adopted as the projection operator to suppress source interferences in the frequency-space domain. The MSSA method is reformulated as a robust optimization problem that includes a low-rank Hankel matrix constraint, written as the product of two matrices of lower dimension obtained by the bifactored gradient descent (BFGD) method.

In the second part of my thesis, I explore an inversion scheme for source separation and source reconstruction that honours actual source coordinates. The proposed method adopts a projected gradient descent optimization with a reduced-rank MSSA projection operator. I propose to adopt an Interpolated-MSSA (I-MSSA) to separate and reconstruct sources in situations where the acquired simultaneous source data correspond to sources with ar- arbitrary irregular-grid coordinates. Additionally, a faster and computational-efficient MSSA (FMSSA) algorithm was applied to speed up the method.

description: This paper provides a theoretical understanding of Deep Q-Network (DQN) with the $\varepsilon$-greedy exploration in deep reinforcement learning. Despite the tremendous empirical achievement of the DQN, its theoretical characterization remains underexplored. First, the exploration strategy is either impractical or ignored in the existing analysis. Second, in contrast to conventional Q-learning algorithms, the DQN employs the target network and experience replay to acquire an unbiased estimation of the mean-square Bellman error (MSBE) utilized in training the Q-network. However, the existing theoretical analysis of DQNs lacks convergence analysis or bypasses the technical challenges by deploying a significantly overparameterized neural network, which is not computationally efficient. This paper provides the first theoretical convergence and sample complexity analysis of the practical setting of DQNs with $ε$-greedy policy. We prove an iterative procedure with decaying $ε$ converges to the optimal Q-value function geometrically. Moreover, a higher level of $ε$ values enlarges the region of convergence but slows down the convergence, while the opposite holds for a lower level of $ε$ values. Experiments justify our established theoretical insights on DQNs.

description: Problem: Human papillomavirus infection is integral to developing invasive cervical cancer in the majority of patients. In a recent genome-wide association study, rs9357152 and rs4243652 have been associated with seropositivity for HPV16 or HPV18, respectively. It is unknown whether these variants also associate with cervical cancer triggered by either HPV16 or HPV18. Methods: We investigate whether the two HPV susceptibility variants show association with type-specific cervical cancer in a genetic case-control study with cases stratified by HPV16 or HPV18, respectively. We further tested whether rs9357152 modulates gene expression of any of 36 genes at the human leukocyte antigen locus in 256 cervical tissues. Results: rs9357152 was associated with invasive HPV16-positive cervical cancer (OR 1.33, 95%CI 1.03–1.70, p = 0.03), and rs4243652 was associated with HPV18-positive adenocarcinomas (OR 2.96, 95%CI 1.18–7.41, p = 0.02). These associations remained borderline significant after testing against different sets of controls. rs9357152 was found to be an eQTL for HLA-DRB1 in HPV-positive cervical tissues (pANOVA = 0.0009), with the risk allele lowering mRNA levels. Conclusions: We find evidence that HPV seropositivity variants at chromosome 6 and 14 may modulate type-specific cervical cancer risk. rs9357152 may exert its effect through regulating HLA-DRB1 induction in the presence of HPV. In regard of multiple testing, these results need to be confirmed in larger studies.

Perfusion-Rate Estimation Using Ultrafast Speckle-Decorrelation Ultrasound Imaging
Creators: Nascimento de Oliveira, Mayara
Publisher: name: University of Alberta Library
Year: 2022

Estimating tissue perfusion has great clinical applications such as the prediction of anti-angiogenic therapies and stroke management. Ultrasound perfusion imaging is preferable than other methods since it has real time capabilities, and it is inexpensive. The method proposed in this study shows the relationship between tissue perfusion and speckle decorrelation rate when high-frequency, high-frame rate ultrasound is used. We also investigated the use of lower frequency ultrasound transducers with high-frame rate, plane wave compounding imaging, and the results are promising. This new approach to estimate tissue perfusion waves the need for contrast agents while providing quantitative information on tissue perfusion (consequently, outperforming PD imaging) as well as morphological information. We combined adaptive block-wise SVD filter, AM2D algorithm for tissue motion compensation and Golay sequences to substantially increase the SNR and therefore increase perfusion sensitivity with the ultimate goal of proving the robustness of this new method and its capability to being used in clinical applications.

description: Psychiatric disorders are among the most intractable enigmas in medicine. In the past five years, there has been unprecedented progress on the genetics of many of these conditions. In this review, we discuss the genetics of nine cardinal psychiatric disorders (Alzheimer’s disease, attention-deficit hyperactivity disorder, alcohol dependence, anorexia nervosa, autism spectrum disorder, bipolar disorder, major depressive disorder, nicotine dependence, and schizophrenia). Empirical approaches have yielded new hypotheses about etiology, and now provide data on the often debated genetic architectures of these conditions, which have implications for future research strategies. Further study using a balanced portfolio of methods to assess multiple forms of genetic variation is likely to yield many additional new findings.
Near Miss and Incident Reporting in a Post-Secondary Institution’s Academic Laboratories
Creators: Hodgson, Greg
Publisher: name: University of Alberta Library
Year: 2022

Incidents and near-misses are common to every workplace and academic laboratories are not exempt. Many academic laboratories conduct high-risk work including working with hazardous materials or dangerous equipment. It is common to hear in an academic laboratory that incidents go unreported, but the question remains if this is truly is the case. This paper examines the near misses and incidents that occur at a large Canadian post-secondary institution with a focus on academic labs with high-risk activities. It explores the number and types of incidents that occur in lab-heavy faculties including science, engineering, and medical disciplines. This paper concludes that although it cannot be conclusively stated that near-misses and incidents are under-reported in academic laboratories, this study provides evidence in support of that hypothesis. In addition, it concludes that there is room for improved near miss and incident reporting.

Geodesic complexity of homogeneous Riemannian manifolds
Creators: name: Mescher, Stephan

Publisher: name: Universitäts- und Landesbibliothek Sachsen-Anhalt
Year: 2023
Subjects: subject: 510

description: We study the geodesic motion planning problem for complete Riemannian manifolds and investigate their geodesic complexity, an integer-valued isometry invariant introduced by D Recio-Mitter. Using methods from Riemannian geometry, we establish new lower and upper bounds on geodesic complexity and compute its value for certain classes of examples with a focus on homogeneous Riemannian manifolds. To achieve this, we study properties of stratifications of cut loci and use results on their structures for certain homogeneous manifolds obtained by T Sakai and others.
Active DNA demethylation: many roads lead to Rome

description: DNA methylation is one of the best-characterized epigenetic modifications and has been implicated in numerous biological processes, including transposable element silencing, genomic imprinting and X chromosome inactivation. Compared with other epigenetic modifications, DNA methylation is thought to be relatively stable. Despite its role in long-term silencing, DNA methylation is more dynamic than originally thought as active DNA demethylation has been observed during specific stages of development. In the past decade, many enzymes have been proposed to carry out active DNA demethylation and growing evidence suggests that, depending on the context, this process may be achieved by multiple mechanisms. Insight into how DNA methylation is dynamically regulated will broaden our understanding of epigenetic regulation and have great implications in somatic cell reprogramming and regenerative medicine.

Centromeres: unique chromatin structures that drive chromosome segregation
Creators: name: Verdaasdonk, Jolien S.
name: Bloom, Kerry
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2011

description: Fidelity during chromosome segregation is essential to prevent aneuploidy. The proteins and chromatin at the centromere form a unique site for kinetochore attachment and allow the cell to sense and correct errors during chromosome segregation. Centromeric chromatin is characterized by distinct chromatin organization, epigenetics, centromere-associated proteins and histone variants. These include the histone H3 variant centromeric protein A (CENPA), the composition and deposition of which have been widely investigated. Studies have examined the structural and biophysical properties of the centromere and have suggested that the centromere is not simply a ‘landing pad’ for kinetochore formation, but has an essential role in mitosis by assembling and directing the organization of the kinetochore.
A generalised formulation of the Laplacian approach to resistor networks
Creators: name: Izmailian, N. Sh.

description: An analytic approach is presented to developing exact expressions for the two-point resistance between arbitrary nodes on certain non-regular resistor networks. This generalises previous approaches, which only deliver results for networks of more regular geometry. The new approach exploits the second minor of the Laplacian matrix associated with the given network to obtain the resistance in terms its eigenvalues and eigenvectors. The method is illustrated by application to the resistor network on the globe lattice, for which the resistance between two arbitrary nodes is obtained in the form of single summation.

description: Cellular signal transduction occurs in complex and redundant interaction networks that are best examined at the level of single cells by simultaneously monitoring the activation dynamics of multiple components. Recent advances in biosensor technology have made it possible to visualize and quantify the activation of multiple network nodes in the same living cell. The precision and scope of this approach has been greatly extended by novel computational approaches to determine the relationships between different networks, studied in separate cells.

description: Современная экологическая ситуация, истощение ресурсов и усиливающаяся глобализация ставит человечество перед выбором нового пути развития. От покорения и перестройки природной среды к сотрудничеству с Природой. Особо важным в деятельности человека стоит вопрос экологизации аграрного труда. Человеческая цивилизация за весь период своего существования пережила две эпохи в агроиндустрии. Человечество является на пороге третьей аграрной мировой революции. Если этого не сделать, то Homo sapiens, как вид, может просто-напросто, исчезнуть с лица Земли.
The 'invisible hand': regulation of RHO GTPases by RHOGDIs
Creators: name: Boulter, Etienne

description: The 'invisible hand' is a term originally coined by Adam Smith in the Theory of Moral Sentiments to describe the forces of self-interest, competition, and supply and demand that regulate the resources in society. This metaphor continues to be used by economists to describe the self-regulating nature of a market economy. The same metaphor can be used to describe the RHO-specific guanine nucleotide dissociation inhibitor (RHOGDI) family, which operates in the background, as an invisible hand, using similar forces to regulate the RHO GTPase cycle.

The study of triple systems V819 Her, V2388 Oph, and V1031 Ori

description: The systems V819 Her, V2388 Oph, and V1031 Ori are triples comprised of an eclipsing binary orbiting with a distant visual component on a longer orbit. A detailed analysis of these interesting systems, combining the two observational techniques: interferometry and apparent period variation, was performed. The interferometric data for these three systems obtained during the last century determine the visual orbits of the distant components in the systems. The combined analysis of the positional measurements together with the analysis of apparent period changes of the eclipsing binary (using the minima timings) can be used to study these systems in a combined approach, resulting in a set of parameters otherwise unobtainable without the radial velocities. The main advantage of the technique presented here is the fact that one needs no spectroscopic monitoring of the visual orbits, which have rather long periods: 5.5 yr for V819 Her, 9.0 yr for V2388 Oph, and 31.3 yr for V1031 Ori, respectively. The eccentricities of the outer orbits are 0.69, 0.33, and 0.92, respectively. Moreover, the use of minima timings of the eclipsing pairs help us to derive the orientation of the orbit in space with no ambiguity around the celestial plane. And finally, the combined analysis yielded also an independent determination of the distance of V819 Her (68.7 +/- 1.8 pc), and V2388 Oph (70.6 +/- 8.9 pc). We also present a list of similar systems, which would be suitable for a combined analysis like this one.

A day in the life of the spliceosome
Creators: name: Matera, A. Gregory
name: Wang, Zefeng
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: One of the most amazing findings in molecular biology was the discovery that eukaryotic genes are discontinuous, interrupted by stretches of non-coding sequence. The subsequent realization that the intervening regions are removed from pre-mRNA transcripts via the activity of a common set of small nuclear RNAs (snRNAs), which assemble together with associated proteins into a spliceosome, was equally surprising. How do cells orchestrate the assembly of this molecular machine? And how does the spliceosome accurately recognize exons and introns to carry out the splicing reaction? Insights into these questions have been gained by studying the life cycle of spliceosomal snRNAs from their transcription, nuclear export and reimport, all the way through to their dynamic assembly into the spliceosome. This assembly process can also affect the regulation of alternative splicing and has implications for human disease.
Queering Food Access: A Qualitative Analysis of Intersectional Lived Experiences of LGBTQIA2S+ University Students with Food Insecurity in the American South
Creators: Lumens, Eli G.
Publisher: name: University of Alberta Library
Year: 2022

Food insecurity affects 29% of adults (2.4 million people) annually in the lesbian, gay, bisexual, transgender, queer, questioning, intersex, agender, asexual, and Two-Spirit (LGBTQIA2S+) community (Gates, 2014). The college and university student population has a similarly high rate of food insecurity with 39% of students reporting experiencing 30-day food insecurity in 2020 (Baker-Smith et al., 2020). However, little research has examined food insecurity amongst the LGBTQIA2S+ community or the college and university student population in detail. To address this, this research examines food access at the intersection of the LGBTQIA2S+ community and the university and college student population, as told by the community itself. A qualitative, community-based approach and methods of PhotoVoice and semi-structured interviews with eight self-identified LGBTQIA2S+ university students studying at the University of North Carolina at Greensboro (UNCG) were used to explore how food access was impacted by participants’ individual LGBTQIA2S+ identities, in addition to physical, socio-cultural, and political environmental factors. Data were analyzed using thematic decomposition analysis guided by intersectionality and queer theories. Findings show that both LGBTQIA2S+ identities and university student status are correlated with increased risk of food insecurity. The research also identifies additional factors such as income and employment, support systems, and the socio-cultural environment, that influence food security for LGBTQIA2S+ university students. Individuals’ lived experiences of food insecurity highlight the importance of an in-depth understanding of intersectionality and the complexity of identities in developing strategies to improve food access and thus decrease food insecurity. To my knowledge, the findings of this study represent the first evidence of community-based food studies research conducted with the guidance of both intersectionality and queer theories. Therefore, the findings of my thesis provide novel insights into experiences with food insecurity, a relevant issue that is increasingly influencing the health and well-being of LGBTQIA2S+ university students.
