description: Large-scale observational health databases are increasingly popular for conducting comparative effectiveness and safety studies of medical products. However, increasing number of patients poses computational challenges when fitting survival regression models in such studies. In this paper, we use graphics processing units (GPUs) to parallelize the computational bottlenecks of massive sample-size survival analyses. Specifically, we develop and apply time- and memory-efficient single-pass parallel scan algorithms for Cox proportional hazards models and forward-backward parallel scan algorithms for Fine-Gray models for analysis with and without a competing risk using a cyclic coordinate descent optimization approach. We demonstrate that GPUs accelerate the computation of fitting these complex models in large databases by orders of magnitude as compared to traditional multi-core CPU parallelism. Our implementation enables efficient large-scale observational studies involving millions of patients and thousands of patient characteristics. The above implementation is available in the open-source R package Cyclops (Suchard et al., 2013).

description: The double parton distributions (dPDF), both conventional and those corresponding to parton splitting, are calculated and compared for different two-parton combinations. The conventional and splitting dPDFs have very similar shape in $x_1$ and $x_2$. We make a first quantitative evaluation of the single-ladder-splitting contribution to double parton scattering (DPS) production of two S- or P-wave quarkonia, two Higgs bosons and $c \bar c c \bar c$. The ratio of the single-ladder-splitting to conventional contributions is discussed as a function of centre-of-mass energy, mass of the produced system and other kinematical variables. Using a simple model for the dependence of the conventional two-parton distribution on transverse parton separation (Gaussian and independent of $x_i$ and scales), we find that the 2v1 contribution is as big as the 2v2 contribution discussed in recent years in the literature. This means that the phenomenological analyses of $σ_{eff}$ including only the conventional DPS mechanism have to be revised including explicitly the single-ladder-splitting contributions discussed here. The differential distributions in rapidity and transverse momenta calculated for conventional and single-ladder-splitting DPS processes are however very similar which causes their experimental separation to be rather difficult, if not impossible. The direct consequence of the existence of the two components (conventional and splitting) is the energy and process dependence of the empirical parameter $σ_{eff}$. This is illustrated in our paper for the considered processes.

description: The promise of high-rate low-density parity check (LDPC) codes to substantially reduce the overhead of fault-tolerant quantum computation depends on constructing efficient, fault-tolerant implementations of logical gates on such codes. Transversal gates are the simplest type of fault-tolerant gate, but the potential of transversal gates on LDPC codes has hitherto been largely neglected. We investigate the transversal gates that can be implemented in hypergraph product codes, a class of LDPC codes. Our analysis is aided by the construction of a symplectic canonical basis for the logical operators of hypergraph product codes, a result that may be of independent interest. We show that in these codes transversal gates can implement Hadamard (up to logical SWAP gates) and control-Z on all logical qubits. Moreover, we show that sequences of transversal operations, interleaved with error correction, allow implementation of entangling gates between arbitrary pairs of logical qubits in the same code block. We thereby demonstrate that transversal gates can be used as the basis for universal quantum computing on LDPC codes, when supplemented with state injection.

description: Higgs boson properties could be studied with a high accuracy at a muon collider via the s-channel resonant production. We consider the situation where the center-of-mass energy of the muon collider is off the resonance above the Higgs mass. We discuss the discovery potential for a generic heavy Higgs boson ($H$) and compare different production mechanisms, including the "radiative return" ($γH$), $Z$-boson associated production ($ZH$) and heavy Higgs pair production ($HA$). These production mechanisms do not sensitively rely on a priori knowledge of the heavy Higgs boson mass. We include various types of Two Higgs Doublet Models for the comparison. We conclude that the radiative return process could provide an important option for both the heavy Higgs discovery and direct measurement of invisible decays at a high energy muon collider.

Year: 2008

description: BackgroundPerchlorate is an environmental contaminant that blocks iodine uptake into the thyroid gland and reduces thyroid hormones. This action of perchlorate raises significant concern over its effects on brain development.ObjectivesThe purpose of this study was to evaluate neurologic function in rats after developmental exposure to perchlorate.MethodsPregnant rats were exposed to 0, 30, 300, or 1,000 ppm perchlorate in drinking water from gestational day 6 until weaning. Adult male offspring were evaluated on a series of behavioral tasks and neurophysiologic measures of synaptic function in the hippocampus.ResultsAt the highest perchlorate dose, triiodothyronine (T3) and thyroxine (T4) were reduced in pups on postnatal day 21. T4 in dams was reduced relative to controls by 16%, 28%, and 60% in the 30-, 300-, and 1,000-ppm dose groups, respectively. Reductions in T4 were associated with increases in thyroid-stimulating hormone in the high-dose group. No changes were seen in serum T3. Perchlorate did not impair motor activity, spatial learning, or fear conditioning. However, significant reductions in baseline synaptic transmission were observed in hippocampal field potentials at all dose levels. Reductions in inhibitory function were evident at 300 and 1,000 ppm, and augmentations in long-term potentiation were observed in the population spike measure at the highest dose.ConclusionsDose-dependent deficits in hippocampal synaptic function were detectable with relatively minor perturbations of the thyroid axis, indicative of an irreversible impairment in synaptic transmission in response to developmental exposure to perchlorate.

Molecular Modeling of Gas Adsorption, Phase Behaviors, and Surface Area Characterization in  Shale Organic Nanoporous Media
Creators: Wang, Yingnan
Publisher: name: University of Alberta Library
Year: 2022

Shale gas plays an increasingly important role in meeting the growing global energy

demand and reducing carbon emissions. Unlike conventional reservoirs, shale, including both

organic and inorganic matter, can have an extensive amount of pores ranging from a few to

hundreds of nanometers. Kerogen, as the main constituent of shale organic matter, has

exceptionally high surface area due to extensive nanoscale pores, in which hydrocarbons behave

very differently from the bulk, and surface adsorption becomes significant due to the strong

fluid–surface interactions. This thesis investigates gas adsorption, phase behaviors, and surface

area characterization in shale organic (kerogen) nanoporous media.

description: The future sixth generation (6G) of communication systems is envisioned to provide numerous applications in safety-critical contexts, e.g., driverless traffic, modular industry, and smart cities, which require outstanding performance, high reliability and fault tolerance, as well as autonomy. Ensuring criticality awareness for diverse functional safety applications and providing fault tolerance in an autonomous manner are essential for future 6G systems. Therefore, this paper proposes jointly employing the concepts of resilience and mixed criticality. In this work, we conduct physical layer resource management in cloud-based networks under the rate-splitting paradigm, which is a promising factor towards achieving high resilience. We recapitulate the concepts individually, outline a joint metric to measure the criticality-aware resilience, and verify its merits in a case study. We, thereby, formulate a non-convex optimization problem, derive an efficient iterative algorithm, propose four resilience mechanisms differing in quality and time of adaption, and conduct extensive numerical simulations. Towards this end, we propose a highly autonomous rate-splitting-enabled physical layer resource management algorithm for future 6G networks respecting mixed-critical quality of service (QoS) levels and providing high levels of resilience. Results emphasize the considerable improvements of incorporating a mixed criticality-aware resilience strategy under channel outages and strict QoS demands. The rate-splitting paradigm is particularly shown to overcome state-of-the-art interference management techniques, and the resilience and throughput adaption over consecutive outage events reveals the proposed schemes contribution towards enabling future 6G networks.

description: This study examines the relation between young adults’ goal achievement, continued goal striving over time, and subsequent well-being. Analysis of a longitudinal subsample of a nationally representative U.S. study of 5,693 adolescents as they transition to adulthood revealed that individuals who met their goals had higher well-being, but that the relation between goal completion and well-being varied by goal content. Continued goal striving was related to well-being and maintained domain-specific self-efficacies, whereas goal disengagement was accompanied by declines in domain-specific self-efficacies. Overall, the results suggest that long-term goal striving is beneficial for well-being during the transition to adulthood.

description: This chapter, dedicated to the memory of Mino Freund, summarizes the Quantum Decision Theory (QDT) that we have developed in a series of publications since 2008. We formulate a general mathematical scheme of how decisions are taken, using the point of view of psychological and cognitive sciences, without touching physiological aspects. The basic principles of how intelligence acts are discussed. The human brain processes involved in decisions are argued to be principally different from straightforward computer operations. The difference lies in the conscious-subconscious duality of the decision making process and the role of emotions that compete with utility optimization. The most general approach for characterizing the process of decision making, taking into account the conscious-subconscious duality, uses the framework of functional analysis in Hilbert spaces, similarly to that used in the quantum theory of measurements. This does not imply that the brain is a quantum system, but just allows for the simplest and most general extension of classical decision theory. The resulting theory of quantum decision making, based on the rules of quantum measurements, solves all paradoxes of classical decision making, allowing for quantitative predictions that are in excellent agreement with experiments. Finally, we provide a novel application by comparing the predictions of QDT with experiments on the prisoner dilemma game. The developed theory can serve as a guide for creating artificial intelligence acting by quantum rules.

Structural and Kinetic Characterization of Disease-Associated Tau Mutants
Creators: Yarahmady, Allan
Publisher: name: University of Alberta Library
Year: 2022

While great advancements have been made in the field of tau biology, one particularly elusive component is the significance of structural variance of tau aggregates linked to disease: we see great structural heterogeneity among the aggregates obtained from various tauopathies despite being made from the same protein. Furthermore, these profiles appear to be consistent across patients with a given disease. This suggests disease-specific cellular triggers that favour certain aggregate structures over others. A better understanding of these differences would bring us closer to defining the critical early stages of disease onset and spread. One way to study this research question is via saturation mutagenesis. Point mutations in tau can have marked effects on aggregate kinetics, structure, and morphology, so this method would allow for a thorough assessment of the sequence-structure relationship for tau aggregation. To achieve this, a high-throughput method of purifying recombinant tau was optimised to be compatible with downstream assays such as those measuring in vitro aggregation kinetics or aggregate core structures resistant to protease digestion. In this thesis, a preliminary screen of our developed platform was performed on 36 tau mutants linked to the tauopathy FTLD-tau. These mutants were found to group into ten structural subtypes.

description: We present an algorithm for the rapid numerical integration of smooth, time-periodic differential equations with small nonlinearity, particularly suited to problems with small dissipation. The emphasis is on speed without compromising accuracy and we envisage applications in problems where integration over long time scales is required; for instance, orbit probability estimation via Monte Carlo simulation. We demonstrate the effectiveness of our algorithm by applying it to the spin-orbit problem, for which we have derived analytical results for comparison with those that we obtain numerically. Among other tests, we carry out a careful comparison of our numerical results with the analytically predicted set of periodic orbits that exists for given parameters. Further tests concern the long-term behaviour of solutions moving towards the quasi-periodic attractor, and capture probabilities for the periodic attractors computed from the formula of Goldreich and Peale. We implement the algorithm in standard double precision arithmetic and show that this is adequate to obtain an excellent measure of agreement between analytical predictions and the proposed fast algorithm.

description: Rotary motors play key roles in energy transduction, from macroscale windmills to nanoscale turbines such as ATP synthase in cells. Despite our capabilities to construct engines at many scales, developing functional synthetic turbines at the nanoscale has remained challenging. Here, we experimentally demonstrate rationally designed nanoscale DNA-origami turbines with three chiral blades. These DNA nanoturbines are 24-27 nm in height and diameter and can utilise transmembrane electrochemical potentials across nanopores to drive DNA bundles into sustained unidirectional rotations of up to 10 revolutions/s. The rotation direction is set by the designed chirality of the turbine. All-atom molecular dynamics simulations show how hydrodynamic flows drive this turbine. At high salt concentrations, the rotation direction of turbines with the same chirality is reversed, which is explained by a change in the anisotropy of the electrophoretic mobility. Our artificial turbines operate autonomously in physiological conditions, converting energy from naturally abundant electrochemical potentials into mechanical work. The results open new possibilities for engineering active robotics at the nanoscale.

Historically and culturally, there have coexisted various forms of performances, be it the Sanskrit classical plays or the traditional performances emerging from the local or the community. Central to the aesthetics of Indian theatre and performance laid the 2000- year-old Nāṭyaśāstra, often compared to Aristotle’s Poetics. This paper will examine one such traditional performance, Rāmavijaya, belonging to the tradition of Ankiyabhaonas in medieval Assam and will locate it within the context of the Nāṭyaśāstra, the canonical guidebook to Indian dramaturgy.

description: We propose to use quantum information notions to characterize thermally induced melting of nonperturbative bound states at high temperatures. We apply tensor networks to investigate this idea in static and dynamical settings within the Ising quantum field theory, where bound states are confined fermion pairs - mesons. An equilibrium signature of meson melting is identified in the temperature dependence of the thermal-state second Rényi entropy, which varies from exponential to power-law scaling. Out of equilibrium, we identify as the relevant signature the transition from an oscillatory to a linear growing behavior of reflected entropy after a thermal quench. These analyses apply more broadly, which brings new ways of describing in-medium meson phenomena in quantum many-body and high-energy physics.

Classification of Holomorphic Mappings of Hyperquadrics from $\mathbb C^2$ to $\mathbb C^3$

description: We give a new proof of Faran's and Lebl's results by means of a new CR-geometric approach and classify all holomorphic mappings from the sphere in $\mathbb C^2$ to Levi-nondegenerate hyperquadrics in $\mathbb C^3$. We use the tools developed by Lamel, which allow us to isolate and study the most interesting class of holomorphic mappings. This family of so-called nondegenerate and transversal maps we denote by $\mathcal F$. For $\mathcal F$ we introduce a subclass $\mathcal N$ of maps which are normalized with respect to the group $\mathcal G$ of automorphisms fixing a given point. With the techniques introduced by Baouendi--Ebenfelt--Rothschild and Lamel we classify all maps in $\mathcal N$. This intermediate result is crucial to obtain a complete classification of $\mathcal F$ by considering the transitive part of the automorphism group of the hyperquadrics.

Convergence of a time discrete scheme for a chemotaxis-consumption model

description: In the present work we propose and study a time discrete scheme for the following chemotaxis-consumption model (for any $s\ge 1$), $$ \partial_t u - Δu = - \nabla \cdot (u \nabla v), \quad \partial_t v - Δv = - u^s v \quad \hbox{in $(0,T)\times Ω$,}$$ endowed with isolated boundary conditions and initial conditions, where $(u,v)$ model cell density and chemical signal concentration. The proposed scheme is defined via a reformulation of the model, using the auxiliary variable $z = \sqrt{v + α^2}$ combined with a Backward Euler scheme for the $(u,z)$-problem and a upper truncation of $u$ in the nonlinear chemotaxis and consumption terms. Then, two different ways of retrieving an approximation for the function $v$ are provided. We prove the existence of solution to the time discrete scheme and establish uniform in time \emph{a priori} estimates, yielding the convergence of the scheme towards a weak solution $(u,v)$ of the chemotaxis-consumption model.

Crossing Borders: A Narrative Inquiry into the Experiences of International Graduate Students

                                                                                              Abstract

In response to the global needs for nursing faculty, and nurses at leadership and advanced clinical practice roles, aspiring students from different countries come to Canada for their graduate nursing education because of the positive reputation and the numerous perceived advantages of the education system. However, many international students come from different social, historical, political, cultural, and educational backgrounds that deeply influence their learning experiences in Canada. Working from a space of the inquirer’s personal experience, the aim of this inquiry was to understand the experiences of international graduate nursing students across time, place, and social contexts. The focus was to unravel the following puzzles: What stories across social, historical, political, cultural, and educational borders shaped our identities? How did our experience in Canada shift our lived stories? Four participants were invited from a Master of Nursing program at a university in Western Canada. Attending to relational ethics, I lived relationally in series of conversations alongside participants on a virtual platform for over a year. Conversations were recorded and transcribed verbatim. My narrative beginnings, participants’ conversations, artifacts shared, and my detailed field notes formed the basis for our narrative accounts. Multiplicity of borders and identity making, border making, border crossing, and border dwelling were the four sustaining threads that resonated across our accounts. These four threads provided insights into our lived experience and our shifting identities across borders. Our stories offered insights into the tensions and the day-to-day challenges that international students face during their learning in Canada. Being aware and acknowledging these experiences could be a step towards addressing the issues of inequity and exclusion in higher education institutions.
Traveling wave solutions to the free boundary incompressible Navier-Stokes equations

Publisher: name: Carnegie Mellon University
Year: 2023
Subjects: Partial Differential Equations

description: This thesis contains work completed in the area of nonlinear partial differential equations, specifically on the analysis of the Navier-Stokes equations which arises from the study of mathematical fluid dynamics. In joint works with Professor Ian Tice, we demonstrate that a certain type of solutions known as traveling wave solutions are generic under a variety of physical considerations. In the first chapter, we provide some background material on the subject and give an overview of the work contained in this thesis. Throughout the thesis we focus on studying a single layer of viscous fluid in a strip-like domain that is bounded below by a flat rigid surface and above by a moving surface. In the second chapter, we report the work completed in [50], where we study the effects of inclination and also construct spatially periodic solutions by allowing the fluid cross section to be periodic in various directions in our analysis. An essential component of our analysis is the development of some new functional analytic properties of a scale of anisotropic Sobolev spaces Xs (Rd) introduced in [53], including that these spaces are an algebra in the supercritical regime s > d/2. In the third chapter, we report our work on the analysis of the equations when we impose the so-called Navier-slip conditions on the fluid bottom, which posits that the tangential fluid velocity is proportional to the tangential stress experienced by the fluid. We demonstrate that the no-slip solutions constructed in [50, 53] can be recovered by the Navier-slip solutions v by sending the characteristic slip length to zero in the appropriate topology. We conclude the thesis by providing a detailed appendix of analysis tools employed throughout our analysis.

The minimal communication cost for simulating entangled qubits

Publisher: name: arXiv
Year: 2022

description: We analyze the amount of classical communication required to reproduce the statistics of local projective measurements on a general pair of entangled qubits, $|Ψ_{AB}>=\sqrt{p}\ |00>+\sqrt{1-p}\ |11>$ (with $1/2\leq p \leq 1$). We construct a classical protocol that perfectly simulates local projective measurements on all entangled qubit pairs by communicating one classical trit. Additionally, when $\frac{2p(1-p)}{2p-1} \log{\left(\frac{p}{1-p}\right)}+2(1-p)\leq1$, approximately $0.835 \leq p \leq 1$, we present a classical protocol that requires only a single bit of communication. The latter model even allows a perfect classical simulation with an average communication cost that approaches zero in the limit where the degree of entanglement approaches zero ($p \to 1$). This proves that the communication cost for simulating weakly entangled qubit pairs is strictly smaller than for the maximally entangled one.

description: Установлено, что у пшеницы сорта Амурская 1495 максимальная урожайность (3,22 т/га) получена при внесении под посев N90Р60 и N90Р60 К60. Основная причина получения низкой урожайности сои – чрезмерное упрощение технологии её возделывания: снижение глубины основной обработки почвы, значительное сокращение внесения фосфорных удобрений, посев сортов сои без учёта их ресурсосберегающих свойств. Выполнение основных требований технологий возделывания сельскохозяйственных культур позволит значительно повысить их урожайность независимо от погодных условий.
