description: State-of-the-art many-body wave function techniques rely on heuristics to achieve high accuracy at an attainable cost to solve the many-body Schrödinger equation. By far the most common property used to assess accuracy has been the total energy; however, total energies do not give a complete picture of electron correlation. In this work, the authors assess the von Neumann entropy of the one-particle reduced density matrix (1-RDM) to compare selected configuration interaction (CI), coupled cluster, variational Monte Carlo, and fixed-node diffusion Monte Carlo for benchmark hydrogen chains. A new algorithm, the circle reject method is presented which improves the efficiency of the evaluation of the von Neumann entropy using quantum Monte Carlo by several orders of magnitude. The von Neumann entropy of the 1-RDM and the eigenvalues of the 1-RDM are shown to distinguish between the dynamic correlation introduced by the Jastrow and static correlation introduced by determinants with large weights, confirming some of the lore in the field concerning the difference between the selected CI and Slater-Jastrow wave functions.

description: The virtual dimensions of both framed and unframed SU(2) magnetic monopoles on asymptotically conic 3-manifolds are obtained by computing the index of a Fredholm extension of the associated deformation complex. The unframed dimension coincides with the one obtained by Braam for conformally compact 3-manifolds. The computation follows from the application of a Callias-type index theorem.

description: We give simple explicit formulas for deformation quantization of Poisson-Lie groups and of similar Poisson manifolds which can be represented as moduli spaces of flat connections on surfaces. The star products depend on a choice of Drinfeľd associator and are obtained by applying certain monoidal functors (fusion and reduction) to commutative algebras in Drinfeľd categories. From a geometric point of view this construction can be understood as a quantization of the quasi-Poisson structures on moduli spaces of flat connections.

description: We have studied the Be/X-ray binary (BeXRB) pulsar eRASSU J050810.4-660653 recently discovered in the Large Magellanic Cloud (LMC). Timing and spectral features of the source have been discussed in detail using NuSTAR \& XMM-Newton observations. Coherent pulsation of the source was detected at $\sim 40.578\;\pm\;0.001$ s using NuSTAR observation. We analyzed pulse profiles of the source in different energy bands using NuSTAR \& XMM-Newton data. The pulse-profile evolved with time but was generally suggestive of a pencil-beam dominated pattern, which combined with the measured luminosity, indicates that the source may be accreting in the sub-critical regime. The pulse fraction follows a linearly increasing trend with photon energy and is anti-correlated with luminosity. In the 1 year interval between the XMM and NuSTAR observations the pulse period shortened by 0.021 s which could be consistent with spin-up or orbital Doppler effect. The average flux of the source in (3-50) keV energy range is found to be $\sim 5.56\;\times\;10^{-11}\;erg\;cm^{-2}\;s^{-1}$ and the corresponding luminosity is $\sim 1.66\;\times\;10^{37}\;erg\;s^{-1}$. The variation of spectral parameters with pulse phase is studied using phase resolved spectroscopy which reveals that the observed photon index becomes harder with increasing flux.

Integrating enhanced efficiency fertilizers and nitrogen rates to improve Canada Western Red Spring wheat production in the Canadian prairies
Creators: Fast, Adam
Publisher: name: University of Alberta Library
Year: 2023

Canada Western Red Spring (CWRS) wheat (Triticum aestivum L.) is the most widely grown wheat class in western Canada. This is mainly due to its excellent milling and baking quality, concomitant with a high protein concentration. Adequate nitrogen (N) supply is important to achieve optimal CWRS grain yield and quality. In CWRS production, N is routinely applied as granular urea fertilizer during planting. Consequential N loss can arise when using unprotected urea fertilizer. Enhanced efficiency fertilizers (EEFs) aim to maintain the integrity of applied N by increasing plant nutrient bioavailability while reducing environmental N loss. To determine if the use of EEFs and different N rates can improve upon conventional methods, a CWRS wheat experiment was established in 2019 across four locations in Alberta and two in Saskatchewan, Canada. This experiment consists of two factors: (i) urea type [(urea; urea + urease inhibitor (Agrotain®); urea + nitrification inhibitor (eNtrench®); urea + dual inhibitor (SuperU®); urea + dual inhibitor (NBPT/DMPSA); and slow-release fertilizer (Environmentally Smart Nitrogen® (ESN®))], and (ii) N rate [60; 120; 180; and 240kg N ha-1]. Results indicate urea type affected grain yield in Dark Brown Chernozem soils but not in Black Chernozem & Dark Grey Luvisol soils. In Dark Brown Chernozem soils, a dual inhibitor (SuperU®) increased grain yield by 3.3% relative to urea, while all other EEFs attained similar results. Furthermore, slight increases in net return were observed with the use of a dual (SuperU®) and urease inhibitor (Agrotain®). Grain protein content was not influenced by urea type; however, increasing N rate in both soil groups resulted in quadratic and linear increases in grain yield and protein content, respectively. Application of N fertilizer at a rate of 120 kg N ha-1 was agronomically optimal and provided greatest net return. These results suggest growers who incorporate dual inhibitors in CWRS wheat production can achieve modest increases in grain yield; moreover, the use of other EEFs will not reduce grain yield or protein content relative to conventional urea.
The Mental Image of Saudi Women Driving in the Media

Subjects: Sociology and social studies of science and technology

description: Among issues pertinent to Saudis, women have occupied a significant position not only in the domestic media but also in the Western media; it is no secret that the media is largely influential on the public when raising issues related to women, be they negative or positive. Whenever the media adopt and support particular attitudes, especially negative ones, the public will move towards the dimension due to the power, inferentiality, and publicity the media enjoy; and thus, in most cases, the public opinion is formed in a manner consistent with the ideas supported by the media. Hence, the significance of the current study can be captured in the following points: 1. Exploring motives and reasons for making Saudi women a subject for research as the advancement of women is not achieved only through focusing on economic, social, political and legal factors. 2. The study should be seen as a scientific addition to academic studies related to the image of women in the media as most previous findings are somewhat outdated, especially since this type of research is relevant to activities and its results are dynamic (i.e., changing). 3. Shedding light on Saudi women and giving them adequate attention as members of the Saudi society helps in enhancing their role in developing their society. The study reached a set of results, including the extent to which Saudi women are capable of driving vehicles, where “average capable” came first, “qualified” came second, and then “incapable” came third
The Entropy of a Vacuum: What Does the Covariant Entropy Count?

description: We argue that a unitary description of the formation and evaporation of a black hole implies that the Bekenstein-Hawking entropy is the "entropy of a vacuum": the logarithm of the number of possible independent ways in which quantum field theory on a fixed classical spacetime background can emerge in a full quantum theory of gravity. In many cases, the covariant entropy counts this entropy--the degeneracy of emergent quantum field theories in full quantum gravity--with the entropy of particle excitations in each quantum field theory giving only a tiny perturbation. In the Rindler description of a (black hole) horizon, the relevant vacuum degrees of freedom manifest themselves as an extra hidden quantum number carried by the states representing the second exterior region; this quantum number is invisible in the emergent quantum field theory. In a distant picture, these states arise as exponentially degenerate ground and excited states of the intrinsically quantum gravitational degrees of freedom on the stretched horizon. The formation and evaporation of a black hole involve processes in which the entropy of collapsing matter is transformed into that of a vacuum and then to that of final-state Hawking radiation. In the intermediate stage of this evolution, entanglement between the vacuum and (early) Hawking radiation develops, which is transferred to the entanglement among final-state Hawking quanta through the evaporation process. The horizon is kept smooth throughout the evolution; in particular, no firewall develops. Similar considerations also apply for cosmological horizons, for example for the horizon of a meta-stable de-Sitter space.

Publisher: name: University of Glasgow
Year: 1997
Subjects: subject: Materials science.

description: Stabbing incidents are of continued concern and the need to quantify the force required to cause a stab-wound is increasingly urgent. Only through an understanding of the mechanics of penetration of human tissue can forensic engineers and pathologists infer, after the event, whether any particular wound track is likely to have been due to homicide, suicide or accident. In stabbing incidents, the main resistance to knife penetration is provided by bone tissue. Structurally, bone is a complex material. It is neither as brittle as a monolithic ceramic nor as ductile as a polymer. Rather, it lies within an intermediate class of material that the author has called "near-brittle" and which exhibits limited damage evolution up to failure. A computational constitutive model of near-brittle bone must be benchmarked against experiments on the real material but it is prudent to perform preliminary static and impact tests on simpler model materials which mimic, in at least one aspect, the behaviour of bone. To bracket this behaviour, for which very little relevant data is available, experiments were therefore done on the two extreme cases, ie brittle monolithic ceramics and ductile polymers. At the same time, experience in computational constitutive modelling of a damaging material was gained using preexisting data on the static behaviour of a ceramic composite. Though quantitatively different from bone, this has a qualitatively similar near-brittle response. The experimental work on ductile materials raised the contentious question of the role of kinetic energy versus momentum during impact. While damage certainly increases with kinetic energy, there may also be a small increase with momentum. There is no simple explanation for any such effect and the results are not conclusive but they do point the way towards additional work. The computational modelling proved difficult. The damage model used by Gibson & Thomson (1995) is erroneous but attempts to devise an accurate substitute were hampered by the nature of the explicit finite element solver. The work concludes with experiments on real bone under static and impact loading, to generate data which is essential if this objective is to be eventually met.

description: Smale's 7-th problem concerns N-point configurations on the 2-dim sphere which minimize the logarithmic pair-energy V_0(r) = -ln r averaged over the pairs in a configuration; here, r is the chordal distance between the points forming a pair. More generally, V_0(r) may be replaced by the standardized Riesz pair-energy V_s(r)= (r^{-s} -1)/s, which becomes - ln r in the limit s to 0, and the sphere may be replaced by other compact manifolds. This paper inquires into the concavity of the map from the integers N>1 into the minimal average standardized Riesz pair-energies v_s(N) of the N-point configurations on the 2-sphere for various real s. It is known that v_s(N) is strictly increasing for each real s, and for s<2 also bounded above, hence "overall concave." It is (easily) proved that v_{-2}(N) is even locally strictly concave, and that so is v_s(2n) for s

The affine semigroup algebra resulting from this degeneration is described using the $K-$Pieri rule from Kac-Moody representation theory. Along the way we give a proof of the $K-$Pieri rule which utilizes the classical Pieri rule and elements of commutative algebra, and we describe a relationship between the Cox ring and a classical invariant ring studied by Weyl.

Animal 3D reconstruction from videos
Creators: Ma, Youdong
Publisher: name: University of Alberta Library
Year: 2023

3D reconstruction of quadruped animals is a challenging problem, where key issues

lie in their large shape variety and deformation within the same animal species as

well as the lack of sufficient training data. In this thesis, we present two approaches

toward this task. Our first approach is a model-based method called SMALF, where a

parametric 3D shape template, SMAL, is employed to recover the 3D pose and shape

of an animal from its raw video. On top of SMAL, our predicted mesh is further

allowed to perform per-vertex deformations: this way, our proposed model benefits

from the use of both parametric and non-parametric representations. Second, we

present AnimalRecon, yet another method that uses a neural implicit function to

represent 3D animal shapes. Neural implicit representation methods enjoy a higher

degree of flexibility and expressiveness due to the continuous nature of this shape

representation. However, how to extract a space-time coherent representation for

a video can be difficult to achieve. First, we implement neural blend skinning, a

method to enable our implicit shape to deform. Our implicit shape model is then

fitted into the given video. Qualitative and quantitative results of our approach

SMALF are conducted on two BADJA and RGBD-Dog datasets, where our method

is demonstrated to improve over the baselines. Our method AnimalRecon is further

examined on the RGBD-Dog dataset, where higher-fidelity 3D reconstruction results

are shown when comparing with the existing efforts.
Have Pulsar Timing Arrays detected the Hot Big Bang? Gravitational Waves from Strong First Order Phase Transitions in the Early Universe

description: The origins of matter and radiation in the universe lie in a Hot Big Bang. We present a number of well-motivated cosmologies in which the Big Bang occurs through a strong first order phase transition -- either at the end of inflation, after a period of kination ("Kination-Induced Big Bang"), or after a second period of vacuum-domination in the early universe ("Supercooled Big Bang"); we also propose a "Dark Big Bang" where only the dark matter in the Universe is created in a first-order phase transition much after inflation. In all of these scenarios, the resulting gravitational radiation can explain the tentative signals reported by the NANOGrav, Parkes and European Pulsar Timing Array experiments if the reheating temperature of the Hot Big Bang, and correspondingly the energy scale of the false vacuum, falls in the range $T_* \sim ρ_{\rm vac}^{1/4} $= MeV--100 GeV. All the same models at higher reheating temperatures will be of interest to upcoming ground- and space-based interferometer searches for gravitational waves at larger frequency.

description: We study the problem of inviscid slightly compressible fluids in a bounded domain. We find a unique solution to the initial-boundary value problem and show that it is near the analogous solution for an incompressible fluid provided the initial conditions for the two problems are close. In particular, the divergence of the initial velocity of the compressible flow at time zero is assumed to be small. Furthermore we find that solutions to the compressible motion problem in Lagrangian coordinates depend differentiably on their initial data, an unexpected result for this type of non-linear equations.

Simulations of Ion Acceleration at Non-relativistic Shocks. I. Acceleration Efficiency

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: We use 2D and 3D hybrid (kinetic ions - fluid electrons) simulations to investigate particle acceleration and magnetic field amplification at non-relativistic astrophysical shocks. We show that diffusive shock acceleration operates for quasi-parallel configurations (i.e., when the background magnetic field is almost aligned with the shock normal) and, for large sonic and Alfvénic Mach numbers, produces universal power-law spectra proportional to p^(-4), where p is the particle momentum. The maximum energy of accelerated ions increases with time, and it is only limited by finite box size and run time. Acceleration is mainly efficient for parallel and quasi-parallel strong shocks, where 10-20% of the bulk kinetic energy can be converted to energetic particles, and becomes ineffective for quasi-perpendicular shocks. Also, the generation of magnetic turbulence correlates with efficient ion acceleration, and vanishes for quasi-perpendicular configurations. At very oblique shocks, ions can be accelerated via shock drift acceleration, but they only gain a factor of a few in momentum, and their maximum energy does not increase with time. These findings are consistent with the degree of polarization and the morphology of the radio and X-ray synchrotron emission observed, for instance, in the remnant of SN 1006. We also discuss the transition from thermal to non-thermal particles in the ion spectrum (supra-thermal region), and we identify two dynamical signatures peculiar of efficient particle acceleration, namely the formation of an upstream precursor and the alteration of standard shock jump conditions.

description: Recent experiments indicate that frictional sliding occurs by the nucleation of detachment fronts at the contact interface that may appear well before the onset of global sliding. This intriguing precursory activity is not accounted for by traditional friction theories but is extremely important for friction dominated geophysical phenomena such as earthquakes, landslides or avalanches. Here we simulate the onset of slip of a three dimensional elastic body resting on a surface and show that experimentally observed frictional precursors depend in a complex non-universal way on the sample geometry and the loading conditions. Our model satisfies Archard's law and Amontons' first and second laws, reproducing with remarkable precision the real contact area dynamics, the precursors' envelope dynamics prior to the transition to sliding, and the normal and shear internal stress distributions close to the slider-substrate interface. Moreover, it allows to assess which experimental features can be attributed to the elastic equilibrium, and which are attributed to the out-of-equilibrium dynamics, suggesting that precursory activity is an intrinsically quasi-static physical process. A direct calculation of the evolution of the Coulomb stress before and during precursors nucleation shows large variations across the sample, which helps to explain why earthquake forecasting methods based only on accumulated slip and Coulomb stress monitoring are often ineffective.

description: We associate a dimer algebra A to a Postnikov diagram D (in a disk) corresponding to a cluster of minors in the cluster structure of the Grassmannian Gr(k,n). We show that A is isomorphic to the endomorphism algebra of a corresponding Cohen-Macaulay module T over the algebra B used to categorify the cluster structure of Gr(k,n) by Jensen-King-Su. It follows that B can be realised as the boundary algebra of A, that is, the subalgebra eAe for an idempotent e corresponding to the boundary of the disk. The construction and proof uses an interpretation of the diagram D, with its associated plabic graph and dual quiver (with faces), as a dimer model with boundary. We also discuss the general surface case, in particular computing boundary algebras associated to the annulus.

Towards Natural Language Modelling of Clinical Depression
Creators: Farruque, Nawshad
Publisher: name: University of Alberta Library
Year: 2023

Traditional survey based methods for clinical depression detection are not always effective; the patient may not reflect their actual mental health condition because of the cognitive bias exhibited while filling out questionnaires about depression. Established through ample earlier work, social media language has been found to be a reflection of a user's real-time mental health status. Being influenced by this potential of social media posts, in this dissertation, we describe a framework for natural language modelling of clinical depression from public social media posts, e.g., tweets from a Twitter user's timeline. Such modelling requires extraction of depression symptoms from the social media posts, then following clinical psychiatry guidelines to calculate depression scores for all two-weeks episodes; then, based on these scores, we infer whether a user is depressed or not. In this process, the first important challenge is the data scarcity for developing a Depression Symptoms Detection (DSD) model.To address data scarcity, we follow two steps. First, we curate a Clinical Expert Annotated Depression Symptoms tweets (CEADS) dataset. We bring important innovations for curating a better quality of CEADS dataset that reflects both clinicians' insights and depression symptoms distribution of self-disclosing depressed Twitter users. Second, we train our DSD model using CEADS dataset and further make the model robust with the help of our proposed Semi-supervised Learning (SSL) framework. In this framework, we iteratively harvest depression symptoms tweets and re-train our DSD model. Moreover, we propose a Zero-Shot Learning (ZSL) model to make our iterative data harvesting process more effective. Further, with the help of the DSD model, we develop our Temporal User-level Clinical Depression Detection (TUD) model that can extract clinical depression scores through a user's Twitter timeline; much like what a depression rating scale, e.g., Patient Health Questionnaire - 9 (PHQ-9) would do. Finally, we draw insightful conclusions on user-level clinical depression modelling by using the following: (1) depression score based features, (2) pure semantic representation based features, along with (3) their temporal representations and (4) experimentations with various clinical depression detection settings in several data distributions. To the best of our knowledge, our experimentations and analyses are unique in the literature.

description: We study front propagation problems for forced mean curvature flows and their phase field variants that take place in stratified media, i.e., heterogeneous media whose characteristics do not vary in one direction. We consider phase change fronts in infinite cylinders whose axis coincides with the symmetry axis of the medium. Using the recently developed variational approaches, we provide a convergence result relating asymptotic in time front propagation in the diffuse interface case to that in the sharp interface case, for suitably balanced nonlinearities of Allen-Cahn type. The result is established by using arguments in the spirit of $Γ$-convergence, to obtain a correspondence between the minimizers of an exponentially weighted Ginzburg-Landau type functional and the minimizers of an exponentially weighted area type functional. These minimizers yield the fastest traveling waves invading a given stable equilibrium in the respective models and determine the asymptotic propagation speeds for front-like initial data. We further show that generically these fronts are the exponentially stable global attractors for this kind of initial data and give sufficient conditions under which complete phase change occurs via the formation of the considered fronts.

Student Perceptions of Participating in a Mindfulness-Based Program in School: A Photovoice-Informed Case Study
Creators: Armstrong, Lisa E.
Publisher: name: University of Alberta Library
Year: 2023

Wellbeing in school-aged children is a systemic and growing public health concern throughout Canada and abroad. School-based health promotion initiatives which utilize a Comprehensive School Health (CSH) approach are one way to address this problem. Research using a CSH approach continues to grow, including research demonstrating the utility of mindfulness-based initiatives in schools for promoting student wellbeing. What is lacking from this body of research are student voices. Therefore, this study explored students’ perceptions of their experiences and impacts of participating in a mindfulness-based initiative, the HeartMath Pilot Program, in the classroom. A qualitative case study utilizing a photovoice-informed method was conducted to gain an understanding of students’ perceptions. Participants included 46 grade five students at a public elementary school in a mid-sized city in Canada. Our findings indicated that students perceived the impact to mainly be the experience of calm, primarily elicited by mindful breathing, and facilitated by practicing in a quiet space, with friends, and/or with a designated teddy bear. The students perceived practicing mindfulness-based skills aided them in reducing stress, facilitating pro-social skills, and in falling asleep. By providing an avenue for grade five students to share their experiences and perceptions in their own words, our findings can inform contextual implementation considerations for future research and practice of mindfulness-based initiatives with students in school-based settings.

An effective and efficient algorithm for the Wigner rotation matrix at high angular momenta

description: The Wigner rotation matrix ($d$-function), which appears as a part of the angular-momentum-projection operator, plays a crucial role in modern nuclear-structure models. However, it is a long-standing problem that its numerical evaluation suffers from serious errors and instability, which hinders precise calculations for nuclear high-spin states. Recently, Tajima [Phys. Rev. C 91, 014320 (2015)] has made a significant step toward solving the problem by suggesting the high-precision Fourier method, which however relies on formula-manipulation softwares. In this paper we propose an effective and efficient algorithm for the Wigner $d$ function based on the Jacobi polynomials. We compare our method with the conventional Wigner method and the Tajima Fourier method through some testing calculations, and demonstrate that our algorithm can always give stable results with similar high-precision as the Fourier method, and in some cases (for special sets of $j, m, k$ and $θ$) ours are even more accurate. Moreover, our method is self-contained and less memory consuming. A related testing code and subroutines are provided as Supplemental Material in the present paper.
Work extraction and thermodynamics for individual quantum systems

description: Thermodynamics is traditionally concerned with systems comprised of a large number of particles. Here we present a framework for extending thermodynamics to individual quantum systems, including explicitly a thermal bath and work-storage device (essentially a `weight' that can be raised or lowered). We prove that the second law of thermodynamics holds in our framework, and give a simple protocol to extract the optimal amount of work from the system, equal to its change in free energy. Our results apply to any quantum system in an arbitrary initial state, in particular including non-equilibrium situations. The optimal protocol is essentially reversible, similar to classical Carnot cycles, and indeed, we show that it can be used it to construct a quantum Carnot engine.

Enhanced prediction of extreme fire weather conditions in spring using the Hot-Dry-Windy Index in Alberta, Canada
Creators: Elliott, Kyle G
Publisher: name: University of Alberta Library
Year: 2023

Fire weather indices used to forecast fire behaviour provide valuable information for wildland fire prevention, preparedness, and suppression. The primary index used in Canada, the Fire Weather Index System, provides qualitative fuel moisture and fire behaviour indices. However, the indices used to predict and forecast fuel moisture and fire behaviour do not assess the impacts of weather alone. Weather strongly influences fuel moisture, fire ignition, and fire spread. Additionally, the spring fire season in Alberta, Canada has been challenging for decades. Alberta has historically experienced extreme fire weather conditions in the spring season, leading to the occurrence of multiple disastrous wildland fires. This study examines the association between the Hot-Dry-Windy Index (HDWI) and spread days on 80 large wildland fires greater than 1,000 hectares that started in the month of May in Alberta from 1990 to 2019. HDWI values were calculated using ERA5 reanalysis weather from the 1000, 975 and 950 hPa levels. Permutation tests were used to test HDWI distributions between spread days and non-spread days. Statistically significant differences between HDWI values were found between the distributions of spread days and non-spread days over the first four days of all 80 large wildland fires in the dataset, as well as on the day of assessment of these fires. Results of this study suggest that HDWI can contribute to the prediction of significant spring wildland fire spread days in Alberta’s fire prone landscapes. A climatology of May HDWI values from 1990 to 2020 was also created for three separate locations in Alberta to provide context to HDWI values.

description: Spatial separation of the wave packets (WPs) of neutrino mass eigenstates leads to decoherence and damping of neutrino oscillations. Damping can also be caused by finite energy resolution of neutrino detectors or, in the case of experiments with radioactive neutrino sources, by finite width of the emitted neutrino line. We study in detail these two types of damping effects using reactor neutrino experiments and experiments with radioactive $^{51}$Cr source as examples. We demonstrate that the effects of decoherence by WP separation can always be incorporated into a modification of the energy resolution function of the detector and so are intimately entangled with it. We estimate for the first time the lengths $σ_x$ of WPs of reactor neutrinos and neutrinos from a radioactive $^{51}$Cr source. The obtained values, $σ_x = (2\times 10^{-5} - 1.4\times 10^{-4})$ cm, are at least six orders of magnitude larger than the currently available experimental lower bounds. We conclude that effects of decoherence by WP separation cannot be probed in reactor and radioactive source experiments.
