Sex-specific Changes in Neonatal Cardiac Mitochondria in Response to Perinatal Iron Deficiency
Creators: Holody, Claudia D
Publisher: name: University of Alberta Library
Year: 2023

Introduction: Iron deficiency (ID) during gestation has been shown to alter growth and developmental trajectories, consequentially increasing the risk of long-term cardiovascular dysfunction in offspring. The heart becomes energetically dependent on mitochondria soon after birth and disturbances in energy metabolism could impact cardiac development. Given that iron is essential for oxygen transport and an important component of the electron transport system, we hypothesized that perinatal ID would alter cardiac mitochondrial function in the neonatal period. Objectives: In hearts of neonatal control and iron-deficient offspring, we sought to (1) perform untargeted proteomics analysis; (2) assess changes in mitochondrial function and reactive oxygen species generation, and (3) explore the mechanisms of iron metabolism underlying these changes. Methods: Female rats were fed an iron-restricted or an iron-replete diet before and during pregnancy. Hearts from neonatal male and female pups underwent quantitative shotgun proteomics analysis. Mitochondrial content and function were assessed by citrate synthase activity and high-resolution respirometry, respectively. Superoxide levels were assessed using dihydroethidium fluorescence. Antioxidant and iron metabolism genes were assessed by RT-qPCR. The effects of ID and postnatal day (PD) were analyzed by fitting a mixed-effects model. Results: Hemoglobin levels were reduced in ID pups at PD0 and PD14 but recovered by PD28. Body weights of ID pups were reduced at all time points, while heart weights (normalized to body weight) were increased. Shotgun proteomics revealed upregulation of mitochondrion organization proteins in ID male hearts. In ID male hearts only, the mitochondrial content, shown by the citrate synthase activity, was increased by 25% while the mitochondrial respiration through the NADH-pathway, succinate-pathway, and FAO-pathway, expressed per citrate synthase activity units, was reduced by up to 50%. ID did not change superoxide or antioxidant enzyme mRNA levels in either sex. Transferrin receptor-1 mRNA was increased in ID females; upregulation of this protein was confirmed by proteomics at PD0. Conclusions: Although male and female neonates experience a similar insult with maternal iron-restriction, only male hearts showed reduced mitochondrial efficiency and compensation by increased mitochondrial content. Lack of changes in other parameters indicate that mitochondria in male ID hearts are likely functional but may have an abnormal protein composition. Further, females may have a greater capacity to prioritize iron for the heart by increasing iron import during ID.

description: In this paper we present a method for single track coincidence measurements using two different track detector materials. We employed plastic and fluorescent nuclear track detectors (PNTDs and FNTDs) in the entrance channel of a monoenergetic carbon ion beam covering the therapeutically useful energy range from 80 to 425 MeV/u. About 99 % of all primary particle tracks detected by both detectors were successfully matched, while 1 % of the particles were only detected by the FNTDs because of their superior spatial resolution. We conclude that both PNTDs and FNTDs are suitable for clinical carbon beam dosimetry with a detection efficiency of at least 98.82 % and 99.83 % respectively, if irradiations are performed with low fluence in the entrance channel of the ion beam. The investigated method can be adapted to other nuclear track detectors and offers the possibility to characterize new track detector materials against well-known detectors. Further, by combining two detectors with a restricted working range in the presented way a hybrid-detector system can be created with an extended and optimized working range.

description: We explain the finite as well as infinite degeneracy in the spectrum of a particular system of spin-1/2 fermions with spin-orbit coupling in three spatial dimensions. Starting from a generalized Runge-Lenz vector, we explicitly construct a complete set of symmetry operators, which span a noncompact SO(3,2) algebra. The degeneracy of the physical spectrum only involves a particular, infinite, so called singleton representation. In the branch where orbital and spin angular momentum are aligned the full representation appears, constituting a 3D analogue of Landau levels. Anti-aligning the spin leads to a finite degeneracy due to a truncation of the singleton representation. We conclude the paper by constructing the spectrum generating algebra of the problem.
Discovering Reward Functions for Language Models
Creators: Hao, Yongchang
Publisher: name: University of Alberta Library
Year: 2023

Language models are a fundamental component of natural language processing (NLP) systems. Numerous successful deployments of modern artificial intelligence systems are based on language models, including GPT-4 and ChatGPT. In practice, they are often trained with the teacher forcing objective, where the goal is to predict the next token given the context. One problem with this objective is that it suffers from inconsistency between training and inference, which leads to compounding errors during the inference phase. Reinforcement learning (RL) is considered a promising approach to address these issues. However, it is usually difficult to design reward functions for language models. Previous attempts at designing reward functions are typically sparse and handcrafted for a specific task only.

In this thesis, we propose a task-agnostic approach that derives a step-wise reward function directly from a model trained with the teacher forcing objective. Our work shows that under a common assumption, language models are trained to implicitly capture the rewards. This simple connection allows us to derive a reward function from any pre-trained language models. The derived reward functions can be used to conduct reinforcement learning for language modeling. We conduct experiments on different sequence-to-sequence tasks, including dialogue and paraphrase generation. Empirical results show that the model trained with our reward function outperforms self-training and reward regression methods on both tasks, confirming the effectiveness of our derivation.
Pekîwe ᐯᑮᐁᐧ Coming Home: Healing Through Land and Cultural Reclamation
Creators: Howse, Robin M
Publisher: name: University of Alberta Library
Year: 2023

This thesis research will explore the ways in which land-based healing and reclamation are interconnected. The Indigenous community members of the Pekîwe Cultural Lodge were both collaborators and co-thinkers in this work. Looking at the social aspects of reclamation through an Indigenous lens provides a rich dialogue that will be valuable to the academic literature in both reclamation and Indigenous studies. A unique Indigenous research method is utilized in these processes. Primary qualitative research data is analyzed, outlining the opportunities and challeneges of reclamation and restoration work with an Indigneous community in centeral Alberta. Additionaly, numerous land-based healing methodologies from some Traditional Knowledge Keepers of Maskwacis are presented here.

This research aims to assist in advancing collaboration and co-management regarding reclamation and restoration work. Additionally, this work aims to inspire and encourage Indigenous academics and community members, especially youth, to pursue their own healing journeys. Hopefully this will result in more brilliant and resilient Indigenous minds achieving their goals and bringing their gifts to life. Some key concepts in this area include self-determination, resurgence, treaties, governance, healing, participatory responsibility, traditional ecological knowledge, ecological integrity, restoration ecology, biocultural restoration, eco-cultural restoration, and reciprocal restoration.
A New Characterization of Comonotonicity and its Application in Behavioral Finance

description: It is well-known that an $\mathbb{R}$-valued random vector $(X_1, X_2, \cdots, X_n)$ is comonotonic if and only if $(X_1, X_2, \cdots, X_n)$ and $(Q_1(U), Q_2(U),\cdots, Q_n(U))$ coincide \emph{in distribution}, for \emph{any} random variable $U$ uniformly distributed on the unit interval $(0,1)$, where $Q_k(\cdot)$ are the quantile functions of $X_k$, $k=1,2,\cdots, n$. It is natural to ask whether $(X_1, X_2, \cdots, X_n)$ and $(Q_1(U), Q_2(U),\cdots, Q_n(U))$ can coincide \emph{almost surely} for \emph{some} special $U$. In this paper, we give a positive answer to this question by construction. We then apply this result to a general behavioral investment model with a law-invariant preference measure and develop a universal framework to link the problem to its quantile formulation. We show that any optimal investment output should be anti-comonotonic with the market pricing kernel. Unlike previous studies, our approach avoids making the assumption that the pricing kernel is atomless, and consequently, we overcome one of the major difficulties encountered when one considers behavioral economic equilibrium models in which the pricing kernel is a yet-to-be-determined unknown random variable. The method is applicable to many other models such as risk sharing model.

description: In five-dimensional universal extra-dimensional models compactified on an $S^1/Z_2$ orbifold four-dimensional kinetic terms are allowed at the two fixed points. If these terms are unequal then Kaluza-Klein (KK) parity is broken. Within such a framework we consider resonant production of the n = 1 KK-gluon at the Large Hadron Collider and its subsequent decay to $t\bar{t}$, where both production and decay are KK-parity non-conserving. We use, for the first time, the exclusion data for a $t\bar{t}$ resonance obtained by the ATLAS collaboration to limit the mass ranges of quark and gluon excitations of the KK-parity-violating model which are found to be in the ballpark of 900 GeV.

description: We present a general covariant action for massive gravity merging together a class of "non-polynomial" and super-renormalizable or finite theories of gravity with the non-local theory of gravity recently proposed by Jaccard, Maggiore and Mitsou (Phys. Rev. D 88 (2013) 044033). Our diffeomorphism invariant action gives rise to the equations of motion appearing in non-local massive massive gravity plus quadratic curvature terms. Not only the massive graviton propagator reduces smoothly to the massless one without a vDVZ discontinuity, but also our finite theory of gravity is unitary at tree level around the Minkowski background. We also show that, as long as the graviton mass $m$ is much smaller the today's Hubble parameter $H_0$, a late-time cosmic acceleration can be realized without a dark energy component due to the growth of a scalar degree of freedom. In the presence of the cosmological constant $Λ$, the dominance of the non-local mass term leads to a kind of "degravitation" for $Λ$ at the late cosmological epoch.

Assessment of Effectiveness of Three Aerosol Mitigation Methods for Orthodontic Debonding
Creators: Souza Carvalho, Ramon
Publisher: name: University of Alberta Library
Year: 2023

Background: The COVID-19 pandemic has shown us that our infection

prevention and control (IPC) knowledge has some glaring gaps on what best ways to

treat dental patients, leading to a flurry of research to understand the best mitigation

strategies to reduce aerosols. One of these strategies was the addition of a Local

Exhaust Ventilation System (LEV), similar to the ones used in other fields as

construction, soldering and chemical engineering. Hypothesis: In this manuscript, we

investigated the additional effect of adding aerosol capture methods during orthodontic

debonding to investigate their added effect to high-volume evacuator (the golden

standard). Materials and Methods: We investigated three mitigation methods during

orthodontic debonding: 1) HVE, 2) HVE and saliva ejector, 3) HVE, saliva ejector and a

LEV device, BriteHive, which shares the dental chair's HVE connector. We have used a

randomized clinical trial approach to investigate whether the three methods are

statistically equivalent from each other (effect size of 0.2 standard deviations ~ 16%

from each other). And measured the aerosols generated from the three mitigation

strategies using two devices, Optical Particle Sizer (OPS) which measures particle

concentration across 13 different particle sizes, and DustTrak, which measures mass

concentration across different particle matter, PM sizes. Results: Mass concentration

showed that HVE and Saliva Ejector strategy had the lowest number of statistically

significant PM sizes, with only the total PM size being statistically significant.

Conclusion: The addition of Saliva Ejector to HVE should supersede both HVE, and

HVE, Saliva Ejector and BriteHive as the gold standard.

An Investigation into Reinforcement Learning in FPGA Placement Optimization
Creators: Chen, Ruichen
Publisher: name: University of Alberta Library
Year: 2023

With the increasing complexity and capacity of modern Field-Programmable Gate Arrays (FPGAs), there is a growing demand for efficient FPGA computer-aided design (CAD) tools, particularly at the placement stage. While some previous works, such as RLPlace, have explored the efficacy of single-state Reinforcement Learning (RL) to optimize FPGA placement by framing it as a multi-armed bandit (MAB) problem, numerous AI techniques remain unexplored due to the outstanding engineering challenges of integrating them into the FPGA CAD flow, which is implemented typically using C++. In this thesis, we propose VPR-Gym, a Python environment built on OpenAI Gym that allows seamless integration with various machine learning libraries, including PyTorch, TensorFlow, and Nevergrad, while enabling the comparison between different AI techniques for FPGA placement optimization. To determine the optimal RL algorithm for FPGA placement, we perform regret analysis and non-stationary analysis of MAB algorithms used in FPGA placement optimization. Moreover, we introduce a learning objective that reformulates the MAB problem as an optimization problem, thereby expanding the range of AI techniques that can be investigated beyond those for MAB problems. To investigate the effectiveness of different algorithms in FPGA placement and thus showcase the capabilities of our VPR-Gym platform, we conduct experiments that compare the performance of various MAB algorithms and evolution strategy (ES) algorithms. Our findings demonstrate that the ES approaches exhibit superior performance over the existing MAB approaches, highlighting the effectiveness of VPR-Gym in facilitating AI research to enhance FPGA placement.

Exploring How the COVID-19 Pandemic Impacted Teacher Expectations in Schools
Creators: Flanagan, Agnes MH
Publisher: name: University of Alberta Library
Year: 2023

Expectations are beliefs that someone should or will achieve something. Expectations influence performance—positive expectations improve outcomes, whereas negative expectations worsen them. We know very little about how teacher expectations changed during the COVID-19 pandemic. This study used a descriptive qualitative approach to explore the impact of the COVID-19 public health measures on expectations in schools. Specifically, teacher expectations for students and for themselves, as well as teachers’ perceptions of their administrators’ expectations for them. Twelve teachers were purposefully sampled across Canada and interviewed in the spring of 2021. Interviews were transcribed and analysed using qualitative content analysis. Five categories were identified. Expectations for students and teachers changed. Students were still expected to do their best but what they were doing looked different. Participants set healthy boundaries and prioritized their well-being due to burnout looming. Administrators made some efforts to be supportive and realistic during this time; however, many participants felt it was not enough. Participants described it was more difficult to develop relationships with students and certain groups of students struggled more than others during the pandemic; both impacting how much teachers could expect of them. The findings contribute to the literature by providing suggestions for future research and proposing an expanded version of a conceptual model for expectations in schools. More importantly, the findings can inform school leaders on how to best support teachers, and how teachers can support and advocate for themselves, during high-stress situations or extreme circumstances, such as a pandemic.

description: This article is devoted to the partial difference quad-graph equations that can be represented in the form $φ(u(i+1,j),u(i+1,j+1))=ψ(u(i,j),u(i,j+1))$, where the map $(w,z) \rightarrow (φ(w,z),ψ(w,z))$ is injective. The transformation $v(i,j)=φ(u(i,j),u(i,j+1))$ relates any of such equations to a quad-graph equation. It is proved that this transformation maps Darboux integrable equations of the above form into Darboux integrable equations again and decreases the orders of the transformed integrals by one in the $j$-direction. As an application of this fact, the Darboux integrable equations possessing integrals of the second order in the $j$-direction are described under an additional assumption. The transformation also maps symmetries of the original equations into symmetries of the transformed equations (i.e. preserves the integrability in the sense of the symmetry approach) and acts as a difference substitution for symmetries of a special form. The latter fact allows us to derive necessary conditions of Darboux integrability for the equations defined in the first sentence of the abstract.

description: Many types of neurons exhibit spike rate adaptation, mediated by intrinsic slow $\mathrm{K}^+$-currents, which effectively inhibit neuronal responses. How these adaptation currents change the relationship between in-vivo like fluctuating synaptic input, spike rate output and the spike train statistics, however, is not well understood. In this computational study we show that an adaptation current which primarily depends on the subthreshold membrane voltage changes the neuronal input-output relationship (I-O curve) subtractively, thereby increasing the response threshold. A spike-dependent adaptation current alters the I-O curve divisively, thus reducing the response gain. Both types of adaptation currents naturally increase the mean inter-spike interval (ISI), but they can affect ISI variability in opposite ways. A subthreshold current always causes an increase of variability while a spike-triggered current decreases high variability caused by fluctuation-dominated inputs and increases low variability when the average input is large. The effects on I-O curves match those caused by synaptic inhibition in networks with asynchronous irregular activity, for which we find subtractive and divisive changes caused by external and recurrent inhibition, respectively. Synaptic inhibition, however, always increases the ISI variability. We analytically derive expressions for the I-O curve and ISI variability, which demonstrate the robustness of our results. Furthermore, we show how the biophysical parameters of slow $\mathrm{K}^+$-conductances contribute to the two different types of adaptation currents and find that $\mathrm{Ca}^{2+}$-activated $\mathrm{K}^+$-currents are effectively captured by a simple spike-dependent description, while muscarine-sensitive or $\mathrm{Na}^+$-activated $\mathrm{K}^+$-currents show a dominant subthreshold component.

description: We study the use of quantum entanglement in the zero-error source-channel coding problem. Here, Alice and Bob are connected by a noisy classical one-way channel, and are given correlated inputs from a random source. Their goal is for Bob to learn Alice's input while using the channel as little as possible. In the zero-error regime, the optimal rates of source codes and channel codes are given by graph parameters known as the Witsenhausen rate and Shannon capacity, respectively. The Lovász theta number, a graph parameter defined by a semidefinite program, gives the best efficiently-computable upper bound on the Shannon capacity and it also upper bounds its entanglement-assisted counterpart. At the same time it was recently shown that the Shannon capacity can be increased if Alice and Bob may use entanglement. Here we partially extend these results to the source-coding problem and to the more general source-channel coding problem. We prove a lower bound on the rate of entanglement-assisted source-codes in terms Szegedy's number (a strengthening of the theta number). This result implies that the theta number lower bounds the entangled variant of the Witsenhausen rate. We also show that entanglement can allow for an unbounded improvement of the asymptotic rate of both classical source codes and classical source-channel codes. Our separation results use low-degree polynomials due to Barrington, Beigel and Rudich, Hadamard matrices due to Xia and Liu and a new application of remote state preparation.

Numerical comparison of a constrained path ensemble and a driven quasisteady state

description: We investigate the correspondence between a non-equilibrium ensemble defined via the distribution of phase-space paths of a Hamiltonian system, and a system driven into a steady-state by non-equilibrium boundary conditions. To discover whether the non-equilibrium path ensemble adequately describes the physics of a driven system, we measure transition rates in a simple one-dimensional model of rotors with Newtonian dynamics and purely conservative interactions. We compare those rates with known properties of the non-equilibrium path ensemble. In doing so, we establish effective protocols for the analysis of transition rates in non-equilibrium quasi-steady states. Transition rates between potential wells and also between phase-space elements are studied, and found to exhibit distinct properties, the more coarse-grained potential wells being effectively further from equilibrium. In all cases the results from the boundary-driven system are close to the path-ensemble predictions, but the question of equivalence of the two remains open.

Strongly Intensive Measures for Transverse Momentum and Particle Number Fluctuations

description: The strongly intensive measures $Δ[P_T,N]$ and $Σ[P_T,N]$ are used to study the event-by-event fluctuations of the transverse momentum $P_T$ and particle multiplicity $N$ in nucleus-nucleus collisions. A special normalization for these fluctuation measures ensures that they are dimensionless and yields a common scale required for a quantitative comparison of fluctuations. In this paper basic properties of the $Δ[P_T, N]$ and $Σ[P_T, N]$ measures are tested within different phenomenological models using the Monte Carlo simulations (the so-called fast generators) and analytical solutions. The obtained results are helpful to elucidate the properties of $Δ[P_T,N]$ and $Σ[P_T,N]$ measures.

Numerical Simulation of Internal Tides and Comparison to Observation
Creators: Li, Kehan
Publisher: name: University of Alberta Library
Year: 2023

As internal tides propagate in the ocean, they carry and dissipate energy over hundreds and even thousands of kilometers. We perform fully nonlinear simulations to examine the evolution of horizontally propagating, vertical mode-1 internal tides in non-uniformly stratified fluids, as it depends on wave amplitude, ocean depth, Coriolis forces, and the spanwise extent of the waves. The background stratification is set up according to ocean measurements southwest of Hawaii and in the South China Sea. Two-dimensional (2D) simulations on the beta-plane are based on the internal tides originating near the Hawaiian Ridge and propagating southwest towards the equator. The results are compared to the ocean measurements from the EXperiment on Internal Tidal Scattering (EXITS). Another series of 2D simulations on the f-plane is set up based on the internal tides propagating westward in the South China Sea and are compared to the observations. The simulations in both research domains align qualitatively and somewhat quantitatively with the observations. A three-dimensional (3D) model simulating spanwise-localized waves is utilized to characterize the evolution of internal tides in the streamwise and spanwise direction. The spanwise evolution of the 3D waves is examined in terms of the lateral spreading, radius of curvature, and sea surface signature. The evolution of sea surface signature is compared favourably to a satellite image in the South China Sea. The 3D model can thus be used to reversely deduce the initial conditions of internal tides.
Cherenkov sound on a surface of a topological insulator

description: Topological insulators are currently of considerable interest due to peculiar electronic properties originating from helical states on their surfaces. Here we demonstrate that the sound excited by helical particles on surfaces of topological insulators has several exotic properties fundamentally different from sound propagating in non-helical or even isotropic helical systems. Specifically, the sound may have strictly forward propagation absent for isotropic helical states. Its dependence on the anisotropy of the realistic surface-states is of distinguished behavior which may be used as an alternative experimental tool to measure the anisotropy strength. Fascinating from the fundamental point of view backward, or anomalous, Cherenkov sound is excited above the critical angle $π/2$ when the anisotropy exceeds a critical value. Strikingly, at strong anisotropy the sound localizes into a few forward and backward beams propagating along specific directions.
