description: We present a unified framework to derive fundamental stellar parameters by combining all available observational and theoretical information for a star. The algorithm relies on the method of Bayesian inference, which for the first time directly integrates the spectroscopic analysis pipeline based on the global spectrum synthesis and allows for comprehensive and objective error calculations given the priors. Arbitrary input datasets can be included into our analysis and other stellar quantities, in addition to stellar age, effective temperature, surface gravity, and metallicity, can be computed on demand. We lay out the mathematical framework of the method and apply it to several observational datasets, including high- and low-resolution spectra (UVES, NARVAL, HARPS, SDSS/SEGUE). We find that simpler approximations for the spectroscopic PDF, which are inherent to past Bayesian approaches, lead to deviations of several standard deviations and unreliable errors on the same data. By its flexibility and the simultaneous analysis of multiple independent measurements for a star, it will be ideal to analyse and cross-calibrate the large ongoing and forthcoming surveys, like Gaia-ESO, SDSS, Gaia and LSST.

description: Entanglement detection and estimation are fundamental in quantum information science. Compared with discrete-variable states, for which lots of efficient entanglement detection criteria and lower bounds of entanglement measures have been proposed, the continuous-variable entanglement is much less understood. Here we shall present a family of entanglement witnesses based on continuous-variable local orthogonal observables (CVLOOs) to detect and estimate entanglement of Gaussian and non-Gaussian states, especially for bound entangled states. By choosing an optimal set of CVLOOs our entanglement witness is equivalent to the realignment criterion and can be used to detect bound entanglement of a class of 2+2 mode Gaussian states. Via our entanglement witness, lower bounds of two typical entanglement measures for arbitrary two-mode continuous-variable states are obtained.

description: We study the field-angle resolved electronic Raman scattering in 2-dimensional d-wave superconducting vortex states theoretically by quasi-classical approximation, the so-called Doppler-shift method. An analytic expression is obtained for the field angle dependence of the Raman scattering amplitude at zero temperature. After numerical integration, we obtain the scattering intensity for various field angles by changing the Raman shift energy. Field-angle resolved electronic Raman scattering turns out to be an effective method for probing unconventional superconducting gap structures. It shows a novel phenomenon: reversal of extrema as a function of frequency without changing temperature or field magnitude.

The Link Between Low Childhood SES and Adult Stress: Evidence from EEG
Creators: Mazidi, Daniel Shafa
Publisher: name: University of Alberta Library
Year: 2023

Low childhood SES has been associated with diminished health and neurocognitive outcomes (Noble et al., 2005), though few studies have examined how the neurological stress response in adults is impacted by socioeconomic factors from childhood. This study uses EEG measures of frontal midline theta (FMT) and P300 to index cognitive control and arousal during economic threat and aversive stimuli presentation. Participants who grew up in lower SES environments showed an increased need for cognitive control indexed by FMT during threat. In those from low SES backgrounds, need for control was found to mediate the relationship between economic uncertainty and distress during aversive stimuli indexed by increased P300 amplitudes during auditory oddball. The results suggest that hypervigilance towards threat and adaptive goal- monitoring for survival in impoverished upbringings may create conflict-processing loops that increase one’s neuro-physiological response towards stressful stimuli later in life. A neurocognitive mechanism of increased stress and reduced emotion regulation (ER) in low childhood SES individuals is presented. Implications for protective factors against reduced ER are discussed.

description: Correlation functions of adiabatic modes in cosmology are constrained by an infinite number of consistency relations, which relate N+1-point correlation functions with a soft-momentum scalar or tensor mode to a symmetry transformation on N-point correlation functions of hard-momentum modes. They constrain, at each order n, the q^n behavior of the soft limits. In this paper we show that all consistency relations derive from a single, master identity, which follows from the Slavnov-Taylor identity for spatial diffeomorphisms. This master identity is valid at any value of q and therefore goes beyond the soft limit. By differentiating it n times with respect to the soft momentum, we recover the consistency relations at each q order. Our approach underscores the role of spatial diffeomorphism invariance at the root of cosmological consistency relations. It also offers new insights on the necessary conditions for their validity: a physical contribution to the vertex functional must satisfy certain analyticity properties in the soft limit in order for the consistency relations to hold. For standard inflationary models, this is equivalent to requiring that mode functions have constant growing-mode solutions. For more exotic models in which modes do not "freeze" in the usual sense, the analyticity requirement offers an unambiguous criterion.

Performing Rhythm: Expressions of Meter in Two Yupik Languages
Creators: Alden, McKinley R.
Publisher: name: University of Alberta Library
Year: 2023

This dissertation is a series of studies that explore the acoustic production of stress, length, non-stress metrical phonology, and other syllable structure altering phenomena in

Central Alaskan Yup’ik and Chugach Alutiiq. The intricate systems of weight, length, and stress that conspire to produce the notable rhythmic pattern in these languages have been the

subject of much theoretical discussion, but little laboratory attention. The studies presented here apply laboratory phonological techniques of acoustic analysis to archival recordings of Yup’ik and Alutiiq. The first of these, which focuses on Yup’ik, examines gemination as a syllable-closing fortition process and addresses the relationship between stress and length. It shows a trichotomy of length among unstressed short, stressed short, and long vowels. The second study focuses on Alutiiq. In addition to a ternary stress-length distinction, Alutiiq metrical phonology also governs onset fortition, tone, and both binary and ternary feet. Moreover, Alutiiq also neutralizes vowel length, making an acoustical examination on metrical production especially interesting. The results show that, like Yup’ik, Alutiiq prefers to maintain a stress-length trichotomy, even where length is targeted for neutralization. They further show that the acoustic correlates of non-stress metrical phonology are considerably more complex than described in the literature. Lastly, the third study presents an exploration of culminativity in both languages. The findings do not provide evidence for word-level culminativity among stressed vowels in either language, which is typologically rare and leads to a discussion on the function of culminativity in metrical systems. The principal contributions of this dissertation include a detailed acoustical analysis of Yup’ik and Alutiiq metrical prosody, a discussion of the implications of this analysis on metrical stress theory, and a demonstration of the application of laboratory analytical methods on archival data.
Persistence personified: understanding the experiences of female first-generation doctoral students
Creators: name: Kohler, Stacey L.
Publisher: name: No Publisher Supplied
Year: 2023

description: The challenges facing first-generation college students are well-documented in the literature, but interestingly, outcomes-based literature for this population is limited. Overall, first-generation college graduates are less likely to enroll in graduate study. Specifically, female first-generation college graduates are less likely than males and female continuing-generation college graduates to enroll in doctoral programs (Holley & Gardner, 2012; Nettles & Millett, 2006). Further limited research is available that describes the experiences of female first-generation college graduates that have navigated the educational pipeline to the doctorate. Using theories related to social and cultural capital and graduate student socialization processes as a framework, this study demonstrates how female first-generation doctoral students continue to accrue the necessary forms of capital throughout their educational journeys. A narrative inquiry approach was used to answer following research questions: (1) What are the experiences of female first-generation students in their doctoral programs? (2) How do female first-generation doctoral students accrue the capital necessary to navigate the demands of doctoral studies to become scholars and practitioners? (3) How do female first-generation doctoral students describe the socialization processes of their respective programs? The experiences of participants were marked by an initial Difficult Adjustment to Doctoral Program (Theme 1) and largely described as an Emotional Rollercoaster (Theme 2). Participants shared stories of Grit and Perseverance (Theme 3) by overcoming obstacles throughout the course of their studies. Participants chronicled how they were able to accrue capital by Relying on Resourcefulness (Theme 4) and Building a Network of Support (Theme 5), thereby fostering resiliency to persist towards degree completion. Lastly, the impact of Relationships with Advisors/Chairs/PIs (Theme 6), Sense of Belonging/Community (Theme 7), and Managing Imposter Syndrome (Theme 8) on the socialization processes of participants was clear. Results inform future research and faculty that work with first-generation doctoral students.

description: We measure the static shear viscosity $η$ in a two-component Fermi gas near a broad collisional (Feshbach) resonance, as a function of interaction strength and energy. We find that $η$ has both a quadratic and a linear dependence on the interaction strength $1/({k_{FI}a})$, where $a$ is the s-wave scattering length and $k_{FI}$ is the Fermi wave vector for an ideal gas at the trap center. For energies above the superfluid transition, the minimum in $η$ as a function of interaction strength is significantly shifted toward the BEC side of resonance, to $1/(k_{FI}a)\simeq 0.25$.

What to do when your discrete optimization is the size of a neural network?
Creators: Silva, Hugo Luis A
Publisher: name: University of Alberta Library
Year: 2023

Oftentimes, machine learning applications using neural networks involve solving discrete optimization problems, such as in pruning, parameter-isolation-based continual learning and training of binary networks. Still, these discrete problems are combinatorial in nature and are also not amenable to gradient-based optimization. Additionally, classical approaches used in discrete settings do not scale well to large neural networks, forcing scientists and empiricists to rely on alternative methods. Among these, two main distinct sources of top-down information can be used to lead the model to good solutions: (1) extrapolating gradient information from points outside of the solution set (2) comparing evaluations between members of a subset of the valid solutions. We take continuation path (CP) methods to represent using purely the former and Monte Carlo (MC) methods to represent the later, while also noting that some hybrid methods combine the two. The main goal of this work is therefore to compare both approaches. For that purpose, we first overview the two classes while also discussing some of their drawbacks analytically. Then, on the experimental section, we compare their performances, starting with smaller Microworld experiments, which allow more fine-grained control of problem variables, and gradually moving towards larger problems in the overparametrized regime, including neural network regression and neural network pruning for image classification, where we additionally compare against magnitude-based pruning. A future version of this work will also include experiments on sequential task learning, which are currently underway.

description: We study the geometry of the twistor space of the universal hyperkaehler implosion Q for SU(n). Using the description of Q as a hyperkaehler quiver variety, we construct a holomorphic map from the twistor space Z_Q of Q to a complex vector bundle over P^1, and an associated map of Q to the affine space R of the bundle's holomorphic sections. The map from Q to R is shown to be injective and equivariant for the action of SU(n) x T^{n-1} x SU(2). Both maps, from Q and from Z_Q, are described in detail for n=2 and n=3. We explain how the maps are built from the fundamental irreducible representations of SU(n) and the hypertoric variety associated to the hyperplane arrangement given by the root planes in the Lie algebra of the maximal torus. This indicates that the constructions might extend to universal hyperkaehler implosions for other compact groups.

description: We present a comprehensive study of the photon energy ($h ν$) dependent line-shape evolution of molecular orbital signals of large $π$-conjugated molecules by resonant photoelectron spectroscopy (RPES). A comparison to RPES data of small molecules suggests that the excitation into different vibrational levels on the intermediate state potential energy surface of the electronic excitation is responsible for the observed effect. In this simplified picture of electron-vibration couping the character of the potential energy surfaces involved in the RPES process determines the line-shape of the molecular orbital signal for a particular $h ν$. We use the sensitivity of this effect to probe the influence of different interfaces on the electron-vibration coupling in the investigated systems. The magnitude of the variation in line-shape throughout the particular $h ν$ region allows to reveal significant differences within the physisorptive regime.

description: We investigate the topological aspect of the spin-triplet $f$-wave superconductor UPt$_3$ through microscopic calculations of edge- and vortex-bound states based on the quasiclassical Eilenberger and Bogoliubov-de Gennes theories. It is shown that a gapless and linear dispersion exists at the edge of the $ab$-plane. This forms a Majorana valley, protected by the mirror chiral symmetry. We also demonstrate that, with increasing magnetic field, vortex-bound quasiparticles undergo a topological phase transition from topologically trivial states in the double-core vortex to zero-energy states in the normal-core vortex. As long as the $d$-vector is locked into the $ab$-plane, the mirror symmetry holds the Majorana property of the zero-energy states, and thus UPt$_3$ preserves topological crystalline superconductivity that is robust against the crystal field and spin-orbit interaction.

Primal-Dual Algorithms for Learning in Constrained Markov Decision Processes

Many real-world tasks in fields such as robotics and control can be formulated as constrained Markov decision processes (CMDPs). In CMDPs, the objective is usually to optimize the return while ensuring some constraints being satisfied at the same time. The primal-dual approach is a common technique of addressing CMDPs. It rewrites the original optimization problem of CMDPs into its equivalent Lagrangian form. In this thesis, we deliver an overview of CMDPs and the primal-dual approach, explain several algorithm designs adopting the primal-dual approach under different learning settings in terms of simulator types, and provide analysis of these algorithms.

description: We present a study of the substructure finder dependence of subhalo clustering in the Aquarius Simulation. We run 11 different subhalo finders on the haloes of the Aquarius Simulation and we study their differences in the density profile, mass fraction and 2-point correlation function of subhaloes in haloes. We also study the mass and vmax dependence of subhalo clustering. As the Aquarius Simulation has been run at different resolutions, we study the convergence with higher resolutions. We find that the agreement between finders is at around the 10% level inside R200 and at intermediate resolutions when a mass threshold is applied, and better than 5% when vmax is restricted instead of mass. However, some discrepancies appear in the highest resolution, underlined by an observed resolution dependence of subhalo clustering. This dependence is stronger for the smallest subhaloes, which are more clustered in the highest resolution, due to the detection of subhaloes within subhaloes (the sub-subhalo term). This effect modifies the mass dependence of clustering in the highest resolutions. We discuss implications of our results for models of subhalo clustering and their relation with galaxy clustering.

description: We investigate the magnetic and metal-insulator (M-I) phase diagram of the 1/5-depleted square-lattice Hubbard model at 1/4 filling by the mean-field approximation. There exist three magnetic phases of nonmagnetic (N), antiferromagnetic (AF), and ferromagnetic (F) types, each realized for the large intrasquare hopping t1, intersquare hopping t2, and Coulomb interaction U, respectively. Within each magnetic phase, the M-I transition of Lifshitz type emerges and, finally, six kind of phases are identified in the U-t1/t2 plane. When t1=t2, we find that the Dirac cone and nearly flat band around the Gamma point form the SU(3) multiplet. The SU(3) effective theory well describes the phase transitions between NI, paramagnetic-metal (PM), and AF phases. The NI and AFI phases are characterized by different Berry phases as in polyacetylene or graphene.

description: Excerpts from the article: Some of the recent advances in probability and mathematical statistics throw considerable light on the theory of errors. Problems that arise in drawing conclusions from observations are essentially statistical and should be handled as such. Unfortunately, the literature on statistics has received but scant notice from writers of treatises on errors. The present paper is the result of an attempt to gather the elements of the statistics of a single sample into one place for ready reference, in order to promote the study of general methods for the interpretation of observational data.

Start-up Analysis of a Partial Nitrification Aerobic Granular Sludge System Treating High-Strength Municipal Digestate Supernatant
Creators: Levicek, Rebecca Dina
Publisher: name: University of Alberta Library
Year: 2023

Ammonia pollution is a growing environmental concern affecting wastewater treatment. With rising concerns about energy consumption and increasingly strict discharge regulations, mitigation of energy expenditure and maintenance of high pollutant removal efficiency have fueled advances in biological wastewater treatment. Partial nitrification AGS-SBR technology has shown potential in treatment efficiency and versatility especially under high pollutant loading. However, neither microbial development nor large-scale operation of such systems has yet been tested. This study therefore focused on identification of changes in microbial community over the course of AGS reactor start-up on a laboratory scale under conditions of increased ammonia loading, and the subsequent operation of pilot scale partial nitrification AGS reactors. The study found that ammonia removal remained above 90% for most of laboratory scale operation with efficiency falling at increased ammonia concentrations. Despite the successful inhibition of NOB, AOB enrichment was low despite high ammonia concentration. The second half of this study focused on the operation of pilot scale AGS partial nitrification SBRs. The pilot system was tested with two different start-up strategies on high ammonia centrate and delivered above 80% removal efficiency. It was found that start-up from activated sludge and partial denitrification AGS was more successful and stable than start-up via UASB granular sludge combined with dehydrated AGS granules. HRT was also optimized during this time suggesting an 8hr cycle was sufficient for the maintenance of 80% ammonia removal efficiency. Denitritation was not successfully implemented in the reactors due to recirculation problems but was overall successful in the mitigation of effluent ammonia levels when treating municipal centrate at the pilot scale.
A qualitative case study of performance poetry
Creators: name: Ashforth, Grace Melane
Publisher: name: No Publisher Supplied
Year: 2023

description: Students must be motivated for deep learning to take place. In high schools in the United States, student motivation is often cited by teachers as difficult to increase. Many teachers identify low student motivation as the number one problem they face in their classrooms. From the perspective of secondary teachers, many students seem relatively uninterested and disengaged in the material. This is likely because the English curriculum is canonical and aimed mostly at students from white, middle-class families. Most texts studied in English courses are written by white men, many of whom are now dead. In a canonical, predetermined curriculum, students have little voice. Performance poetry framed within the tenets of Culturally Relevant Pedagogy (CRP) can be used in English classes to increase student engagement and motivation for all students. While there is a plethora of literature centered on student motivation and pedagogy in English classrooms, much of this literature lacks a focus specifically on performance poetry and CRP, and an even smaller amount of this research is centered on students’ perspectives and experiences. As a result, the current qualitative case study sought to shed light on the impact of teaching a performance poetry unit by a teacher engaged with CRP on student engagement and motivation. Drawing on classroom observations, focus groups, and an analysis of student work samples, the study explored how performance poetry can be taught in English classrooms in order to better engage students in the learning process. Results from this study indicated that the teacher was successful in teaching the performance poetry unit as students were engaged more deeply in the learning process. Students’ voices and performances indicated that the teacher maintained high expectations, facilitated the learning of cultural competence, and assisted students in gaining a sense of sociopolitical consciousness. As a result of a relatable and choice-driven unit, students were more invested in their work and were better able to master the content being taught, while also learning to question the world around them and fighting against issues they see in their own societies. Further research with a larger and more diverse population is needed in order to more confidently generalize the findings and to truly understand how the tenets of CRP can be utilized to better benefit students in the learning process.
Improving photon detector efficiency using a high-fidelity optical CNOT gate

description: A significant problem for optical quantum computing is inefficient, or inaccurate photo-detectors. It is possible to use CNOT gates to improve a detector by making a large cat state then measuring every qubit in that state. In this paper we develop a code that compares five different schemes for making multiple measurements, some of which are capable of detecting loss and some of which are not. We explore how each of these schemes performs in the presence of different errors, and derive a formula to find at what probability of qubit loss is it worth detecting loss, and at what probability does this just lead to further errors than the loss introduces.

Some Notes on Least Squares

description: Excerpts from the Preface: A bit of history will be helpful to anyone who may be wondering just how this brochure happens to be in existence. Beginning in 1932 the author has given annually a course in statistics at the Department of Agriculture Graduate School. The course consists of a survey of classical probability and an introduction to modern theoretical statistics, with some philosophy mixed in with it in an attempt to separate the mathematical developments from observations on the physical behavior of nature. The last six weeks of the course are devoted to the study of least squares. It is the lecture notes for this part of the course for 1937 that now appear. The assumption is that the reader knows when he needs to use least squares and when he should not, that is, when the question can be answered at all. In the course of study in which these notes have grown up, such things are discussed before least squares is commenced; the material presented here may therefore be regarded purely as an exposition on the principle and method. Naturally I have been partial to my own experience, which has embraced consultation on a wide variety of problems, mostly in the Department of Agriculture and the National Bureau of Standards. I have tried to stress points that have seemed inadequately covered or incorrectly pictured by previous writers. It is presumed that teachers using this as a text will heed the references for supplementary reading and will also illustrate the theoretical exercises with numerical examples.
