Improving the Analysis of Nitrogen-Containing Organics in Source Water
Creators: Carroll, Kristin
Publisher: name: University of Alberta Library
Year: 2023

Drinking water treatment is a necessary practice for the elimination of waterborne disease. The study of drinking water treatment can be challenging as large portions of the composition of the source water used by treatment plants remains unknown. In Chapter 1, I review the importance of drinking water treatment, and potential challenges and concerns it faces. I then review current methods used for the analysis of water. While analytical methods are becoming well developed, a remaining challenge is in the data analysis for the identification of new compounds in water. I draw attention to available platforms and some limitations that remain. I emphasize the importance of the careful application of available data analysis programs and important considerations when they are developed.    In Chapter 2, a stable isotopic labelling, high-performance liquid chromatography (HPLC) – high resolution mass spectrometry (HRMS) method is applied for the analysis of amine containing species in source water. Previously, data analysis for this method had been done manually. Here, I compare the manual data analysis with a pilot program we developed, HDPairFinder. Two source water samples were analyzed and the various parameters to select peaks on considered.  I reviewed the benefits of each type of data analysis, differences between the pairs selected, and the possibility for further application of this program to source water samples.     In Chapter 3, I first review the final development of HDPairFinder and the merits it can provide to the data analysis procedure. Following the development of HDPairFinder, I applied it to analyze various groups of samples. Using HDPairFinder, I was able to analyze the composition of the samples over the course of spring runoff. Differences between sampling locations, sampling years, and stage of the water disinfection process were observed. Additionally, I investigated the potential use of pooled samples for the ability to be used as quality controls in the future. Overall, the application of HDPairFinder was able to help in the analysis of temporal trends in amine containing compounds in source water.     This thesis worked to improve the complete analysis procedure for amine containing compounds in source water. Through the development of HDPairFinder many improvements to data analysis were made. These improvements included automated data processing, reduced time for data analysis, and additional data cleaning steps. Additionally, multiple samples can be processed and therefore HDPairFinder is applied to study changes over time. In the application, HDPairFinder helped to provide insight into the composition and changes in composition over the course of spring runoff. This work will help to lay a foundation for future identification of amine containing compounds in the future. In the identification of these compounds, we hope to provide insight into how to improve water treatment in the future.

description: We study how to enable auctions in the big data context to solve many upcoming data-based decision problems in the near future. We consider the characteristics of the big data including, but not limited to, velocity, volume, variety, and veracity, and we believe any auction mechanism design in the future should take the following factors into consideration: 1) generality (variety); 2) efficiency and scalability (velocity and volume); 3) truthfulness and verifiability (veracity). In this paper, we propose a privacy-preserving construction for auction mechanism design in the big data, which prevents adversaries from learning unnecessary information except those implied in the valid output of the auction. More specifically, we considered one of the most general form of the auction (to deal with the variety), and greatly improved the the efficiency and scalability by approximating the NP-hard problems and avoiding the design based on garbled circuits (to deal with velocity and volume), and finally prevented stakeholders from lying to each other for their own benefit (to deal with the veracity). We achieve these by introducing a novel privacy-preserving winner determination algorithm and a novel payment mechanism. Additionally, we further employ a blind signature scheme as a building block to let bidders verify the authenticity of their payment reported by the auctioneer. The comparison with peer work shows that we improve the asymptotic performance of peer works' overhead from the exponential growth to a linear growth and from linear growth to a logarithmic growth, which greatly improves the scalability.

Predicting Verbal Episodic Memory Using Hippocampal Volumetric Features: A Machine Learning-Based Approach
Creators: Hoang, Kim Ngan
Publisher: name: University of Alberta Library
Year: 2023

Verbal memory is an aspect of episodic memory that is especially sensitive to the negative effects of age. Hippocampus has been implicated in immediate and delayed recall of verbal memory with subregions along the long-axis (head, body, tail) and its cellularly distinct subfields (dentate gyrus (DG), cornu ammonis 1-3 (CA1-3), and subiculum (Sub) play dissociable roles in supporting recall performance. High-dimensional neuroimaging datasets and machine learning have been used to estimate and predict verbal memory performance in older adults, but simpler models with hippocampal volumetric features have not been explored. With a sample of cognitively healthy adults spanning a large age range, we have for the first time demonstrated the validity of machine learning-based models predicting verbal memory performance using manually segmented hippocampal anteroposterior subregions and subfields. While the statistical results did not detect dissociable patterns of association between hippocampal volumes and verbal memory, the feature importance results supported the hypothetical functional specialization of hippocampal subregions and subfields in immediate and delayed recall. Consistent with past literature, the accurate individual-level prediction of immediate recall score was related to areas from all subregions while areas in the posterior hippocampus were related to the accurate estimation of delayed recall score. DG contributed to improved immediate recall prediction while Sub was an important feature for delayed recall prediction. This result emphasizes the importance of using regions of interest consistent with previous literature in developing memory performance prediction models.

description: It is now commonly believed that the ground state entanglement spectrum (ES) exhibits universal features characteristic of a given phase. In this letter, we show that this belief is false in general. Most significantly, we show that the entanglement Hamiltonian can undergo quantum phase transitions in which its ground state and low energy spectrum exhibit singular changes, even when the physical system remains in the same phase. For broken symmetry problems, this implies that the ES and the Renyi entropies can mislead entirely, while for quantum Hall systems the ES has much less universal content than assumed to date.

description: Die Vorstellung der passiv-friedfertigen Frau und des aktiv-aggressiven Mannes findet nicht nur in den traditionellen Bildern des männlichen Schurken und der Opferheldin Ausdruck, sondern wird implizit selbst in den wegweisenden kulturkritischen Werken Klaus Theweleits und Elisabeth Bronfens sichtbar, die ihr Erkenntnisinteresse zuerst auf männliche Subjektpositionen – Männerfantasien – richten. Sie führt in Gattungstheorien zu Ausblendungen und drückt sich in Klischees von Mütterlichkeit und weiblicher Zurückhaltung im Arbeitsleben mit realer Wirkung aus. Ausgehend von Figuren wie der Täterin Nike im Roman Die Hirnkönigin der deutschsprachigen Autorin Thea Dorn zeichne ich die kulturelle Wandlung von der Opferheldin zur Monsterheldin nach – zu einer Figuration, die auf neue Möglichkeiten der Identifikation und auf die Notwendigkeit verweist, die Zusammenhänge von Gender, Genre und Gewaltdarstellung neu zu diskutieren.

Guarantees for Self-Play via Polymatrix Decomposability
Creators: MacQueen, Revan
Publisher: name: University of Alberta Library
Year: 2023

Self-play is a technique for machine learning in multi-agent systems where a learning algorithm learns by interacting with copies of itself. Self-play is useful for generating large quantities of data for learning, but has the drawback that  agents the learner will face post-training may have dramatically different behaviour than the learner came to expect by interacting with itself. For the case of two-player constant-sum games, self-play that reaches Nash equilibrium is guaranteed to produce strategies that cannot lose utility from their equilibrium value against any post-training opponent; however, no such guarantee exists for multi-player games.

We show that in games that approximately decompose into a set of two-player constant-sum games (called polymatrix games) where global $\epsilon$-Nash equilibria are boundedly far from Nash-equilibria in each subgame (called subgame stability), any no-external-regret algorithm that learns  by self-play will produce a strategy with bounded loss of utility against new agents, which we call vulnerability. In approximate subgame stable constant sum polymatrix (SS-CSP) games, the strategies produced by self-play are also exchangeable and have values that fall into a bounded range. We extend these results to extensive-form games and give an efficient representation and algorithm for such a decomposition. We demonstrate our findings through experiments on Kuhn and Leduc poker. Finally, we extend our results to games which are strategically equivalent to SS-CSP games. For the first time, our results identify a structural property of multi-player games that enable performance guarantees for the strategies produced by a broad class of self-play algorithms.

The bivariate Krawtchouk polynomials occur as matrix elements of the unitary reducible representations of SO(3) on the energy eigenspaces of the 3-dimensional isotropic harmonic oscillator and the explicit formula is obtained from the decomposition of these representations into their irreducible components. The decomposition entails expanding the Cartesian basis states in the spherical bases that span irreducible SO(3) representations. The overlap coefficients are obtained from the Clebsch-Gordan problem for the su(1,1) Lie algebra.

description: We develop a general theory for a quantum-walk search on a star graph. A star graph has N edges each of which is attached to a central vertex. A graph G is attached to one of these edges, and we would like to find out to which edge it is attached. This is done by means of a quantum walk, a quantum version of a random walk. This walk contains O(\sqrt{N}) steps, which represents a speedup over a classical search, which would require O(N) steps. The overall graph, star plus G, is divided into two parts, and we find that for a quantum speedup to occur, the eigenvalues associated with these two parts in the N goes to infinity limit must be the same. Our theory tells us how the initial state of the walk should be chosen, and how many steps the walk must make in order to find G.

Simulation-Based Lean Framework to Improve Window-Manufacturing Production System
Creators: Azakir, Omar
Publisher: name: University of Alberta Library
Year: 2023

The construction industry has been long recognized for its low productivity, lack of digitalization, and a reduced appetite for innovation. This has shed light on industrialization as paradigm to ensure the successful implementation of construction projects through offsite construction methods. As such, key industry participants are scaling up their production, which enables them to position themselves in a firmly competitive market in terms of strategic R&D facilities and adoption of technological advancements systems to create a diverse array of innovative products. These companies compete based on manufacturing processes, productivity, efficiency, waste minimization, and quality, all of which cater to cost reduction, faster delivery, higher quality, and a better work environment. Implementing lean simulation, multi-criterion decision making (MCDM), and experiment techniques in an Offsite Construction (OSC) facility are essential decision-making tools in a volatile market. Value stream mapping (VSM) is effective in visualizing the production process and identifying waste. However, this tool has its shortcomings and challenges on a case-by-case basis. Therefore, researchers propose to merge it with simulation-based methods to overcome its deficiencies. Simulation has been proven to be a valuable tool to test potential solutions and showcase their impact. The OSC is rich with case studies that have successfully combined both tools. However, there is limited research on incorporating Choosing by Advantages (CBA) as a mechanism to objectively filter the potential set of solutions prior to testing. This is expected to reduce the effort needed in testing and analyzing the solution, and will ensure an objective and collaborative selection process. Additionally, most solutions are tested theoretically through developing simulation models, with limited attention given to conducting hands-on experiments. This research aims to present a framework to assess and improve the state of OSC. This can be achieved through an application of VSM and simulation, with the aid of CBA and other experiments. The developed framework was successfully tested on a window and door OSC facility. This system can ultimately provide management with a valuable decision support system to improve the state of the production line, enhance the well being of the workers, and make the workplace more inclusive.

description: The Kondo scale TK for impurity systems is expected to guarantee universal scaling of physical quantities. However, in practice, not every definition of TK necessarily supports this notion away from the strict scaling limit. Specifically, this paper addresses the role of finite bandwidth D in the strongly-correlated Kondo regime. For this, various theoretical definitions of TK are analyzed based on the inverse magnetic impurity susceptibility at zero temperature. While conventional definitions in that respect quickly fail to ensure universal Kondo scaling for all D, this paper proposes an altered definition of TK_{sc} that allows universal scaling of dynamical or thermal quantities for a given fixed Hamiltonian. If the scaling is performed with respect to an external parameter which directly enters the Hamiltonian, such as magnetic field, the corresponding TK_{sc;B} for universal scaling differs, yet becomes equivalent to TK_{sc} in the scaling limit. The only requirement for universal scaling in the full Kondo parameter regime with a residual error of less than 1% is a well-defined isolated Kondo feature with TK < 0.01D. By varying D over a wide range relative to the bare energies of the impurity, for example, this allows a smooth transition from the Anderson to the Kondo model.

Navigation in Adversarial Environments Guided by PRA* and a Local RL Planner
Creators: Ray, Debraj
Publisher: name: University of Alberta Library
Year: 2023

Real-time strategy games require players to respond to short-term challenges (micromanagement) and long-term objectives (macromanagement) simultaneously to win. However, many players excel at one of these skills but not both. This research studies whether the burden of micromanagement can be reduced on human players through delegation of responsibility to autonomous agents. In particular, this research proposes an adversarial navigation architecture that enables units to autonomously navigate through places densely populated with enemies by learning to micromanage itself. Our approach models the adversarial pathfinding problem as a Markov Decision Process (MDP) and trains an agent with reinforcement learning on this MDP. We observed that our approach resulted in the agent taking less damage from adversaries while traveling shorter paths, compared to previous approaches on adversarial navigation. Our approach is also efficient in memory use and computation time. Interestingly, the agent using the proposed approach outperformed baseline approaches while navigating through environments that are significantly different from the training environments. Furthermore, when the game design is modified, the agent discovers effective alternate strategies considering the updated design without any changes in the learning framework. This property is particularly useful because in game development the design of a game is often updated iteratively.

Cldn2-Trpv6 Double Knockout Mice have Hypocalcaemia and Reduced Bone Mineral Densit
Creators: Bhullar, Harneet
Publisher: name: University of Alberta Library
Year: 2023

Central to calcium homeostasis and bone health is adequate intestinal calcium absorption.

Calcium from the diet is absorbed via either a transcellular or a paracellular pathway both of

which are regulated by calciotropic hormones. In cases of low dietary calcium availability, a

transcellular pathway that relies at least in part on the apical calcium channel Trpv6

predominates. However, when calcium is abundant in the diet, paracellular calcium absorption

occurs through tight junction proteins, including claudin-2 (Cldn2). This tight junction protein

also plays a role in calcium reabsorption from the renal proximal tubule to help maintain overall

calcium balance. Despite this, Cldn2 knockout mice only display mildly altered calcium

homeostasis. Specifically, they have hypercalciuria without evidence of altered bone mineral

density (BMD), plasma calcium or calciotropic hormone levels. Similarly, mice homozygous for

a non-functional Trpv6 (TRPV6D541A/D541A) channel have reduced intestinal calcium absorption

without altered urine or plasma calcium levels, yet only display reduced intestinal calcium

absorption when fed a low calcium diet. We hypothesized that the lack of a more pronounced

phenotype in these two murine models was due to the compensation of one pathway in the

absence of the other. To test this hypothesis, we crossed claudin-2 knockout mice with mice

expressing the mutant Trpv6, generating a functional double knockout (dko, Cldn2-/-/

TRPV6D541A/D541A mice). The dko mice displayed hypocalcaemia and a significant renal calcium

leak. In contrast to the single claudin-2 KO mice or single TRPV6D541A/D541A mutant animals the

dko mice had elevated plasma calcitriol and parathyroid hormone. Moreover, BMD was reduced

in the dko mice. RT-qPCR of intestinal segments and whole kidney revealed increased calbindin-

D9k expression in the proximal colon (but not duodenum) and calbindin-D28k in the kidneys,

consistent with compensatory increased transcellular absorption from the colon and distal

nephron. Together these results are consistent with the paracellular pathway compensating for

the loss of transcellular calcium absorption from the intestine.
Orthosymplectic, Periplectic, and Twisted Super Yangians

This dissertation establishes various structural and representation theoretic results in super Yangian theory.

In its first part, this dissertation details the algebraic structure and representation theory for the Yangians of orthosymplectic Lie superalgebras. Addressing these Yangians via the RTT realization, we prove a Poincaré-Birkhoff-Witt-type theorem and provide a thorough study of the algebraic structure of their extended Yangians. The main result of this part, and of this dissertation, is the provision of many necessary conditions for the irreducible representations of these orthosymplectic Yangians to be finite-dimensional; furthermore, there is much progress made to address attaining sufficient conditions as well. These representation theoretic results are accomplished via the development of a highest weight theory, and such necessary conditions are given in terms of highest weights and tuples of Drinfel'd polynomials.

The second part of this dissertation is devoted to the Yangians of periplectic Lie superalgebras and the twisted Yangians associated to symmetric superpairs of type AIII.

Via the RTT formalism, we prove many structural results for the Yangians of type P strange Lie superalgebras that have only so far been established for the Yangians of type Q strange Lie superalgebras, including a proof of a Poincaré-Birkhoff-Witt-type theorem.

The twisted super Yangians of type AIII are defined along with many structural properties established. We lay the foundation for the classification of their finite-dimensional irreducible representations by cultivating a highest weight theory and proving that all finite-dimensional irreducible modules must be highest weight.
Sturmian theory of three-body recombination: application to the formation of H$_2$ in primordial gas

description: A Sturmian theory of three-body recombination is presented which provides a unified treatment of bound states, quasi-bound states, and continuum states. The Sturmian representation provides a numerical quadrature of the two-body continuum which may be used to generate a complete set of states within any desired three-body recombination pathway. Consequently, the dynamical calculation may be conveniently formulated using the simplest energy transfer mechanism, even for reactive systems which allow substantial rearrangement. The Sturmian theory generalizes the quantum kinetic theory of Snider and Lowry [J. Chem. Phys. 61, 2330 (1974)] to include metastable states which are formed as independent species. Steady-state rate constants are expressed in terms of a pathway-independent part plus a non-equilibrium correction which depends on tunneling lifetimes and pressure. Numerical results are presented for H$_2$ recombination due to collisions with H and He using quantum mechanical coupled states and infinite order sudden approximations. These results may be used to remove some of the uncertainties that have limited astrophysical simulations of primordial star formation.

Approximation Algorithms for Directed Steiner Tree and Traveling Salesman Problems
Creators: Mousavi Haji, Seyyed Ramin
Publisher: name: University of Alberta Library
Year: 2023

In this thesis, we design approximation algorithms for a variety of problems in Network Design. The first problem we consider is the Directed Steiner Tree (DST) problem where we want to find a cheapest way of connecting a subset of nodes (terminal nodes) from a root node in a directed network. We give the first logarithmic approximation algorithm for DST on planar graphs.

Another restriction of DST we consider is to quasi-bipartite instances on planar graphs. In these instances the underlying graph is planar and no two non-terminal nodes are adjacent. Here we get the first constant factor approximation. We further extend this result to a more general family of graphs called minor-free graphs. Our approach is based on a non-standard primal-dual framework and also bounds the integrality gap of the classical linear programming (LP) relaxation for DST.

The third problem we study is a variant of the Traveling Salesman Problem (TSP), one the most famous problem in combinatorial optimization. In TSP, we are given a set of cities, the task is to find a minimum cost tour (closed walk) visiting all the cities. We initiate the study of generalization of TSP, where we are interested in tours that respect some given degree bounds, i.e., a feasible tour must not pass through a location more than a given bound. We further generalize this problem to the setting where we only need to visit a subset of locations in the network. It is easy to see unless P=NP, we cannot hope for an algorithm that does not violate the degree bounds at all. On the other hand, the problems we consider are a generalization of TSP, therefore approximating the cost factor better than the approximation factor for TSP is a very challenging problem. In this thesis, we study the trade-offs between the cost of the tour and the degree violation of the nodes in the tour. We develop LP-based rounding algorithms for these TSP variants which in turn bound the integrality gap of a natural LP relaxations for these problems.

Simple analytical approximations for treatment of inverse Compton scattering of relativistic electrons in the black-body radiation field

description: The inverse Compton (IC) scattering of relativistic electrons is one of the major gamma-ray production mechanisms in different environments. Often the target photons for the IC scattering are dominated by black (or grey) body radiation. In this case, the precise treatment of the characteristics of IC radiation requires numerical integrations over the Planckian distribution. Formally, analytical integrations are also possible but they result in series of several special functions; this limits the efficiency of usage of these expressions. The aim of this work is the derivation of approximate analytical presentations which would provide adequate accuracy for the calculations of the energy spectra of up-scattered radiation, the rate of electron energy losses, and the mean energy of emitted photons. Such formulae have been obtained by merging the analytical asymptotic limits. The coefficients in these expressions are calculated via the least square fitting of the results of numerical integrations. The simple analytical presentations, obtained for both the isotropic and anisotropic target radiation fields, provide adequate (as good as $1\%$) accuracy for broad astrophysical applications.

description: A topology preserving skeleton is a synthetic representation of an object that retains its topology and many of its significant morphological properties. The process of obtaining the skeleton, referred to as skeletonization or thinning, is a very active research area. It plays a central role in reducing the amount of information to be processed during image analysis and visualization, computer-aided diagnosis or by pattern recognition algorithms. This paper introduces a novel topology preserving thinning algorithm which removes \textit{simple cells}---a generalization of simple points---of a given cell complex. The test for simple cells is based on \textit{acyclicity tables} automatically produced in advance with homology computations. Using acyclicity tables render the implementation of thinning algorithms straightforward. Moreover, the fact that tables are automatically filled for all possible configurations allows to rigorously prove the generality of the algorithm and to obtain fool-proof implementations. The novel approach enables, for the first time, according to our knowledge, to thin a general unstructured simplicial complex. Acyclicity tables for cubical and simplicial complexes and an open source implementation of the thinning algorithm are provided as additional material to allow their immediate use in the vast number of practical applications arising in medical imaging and beyond.
