description: Automata for unordered unranked trees are relevant for defining schemas and queries for data trees in Json or Xml format. While the existing notions are well-investigated concerning expressiveness, they all lack a proper notion of determinism, which makes it difficult to distinguish subclasses of automata for which problems such as inclusion, equivalence, and minimization can be solved efficiently. In this paper, we propose and investigate different notions of "horizontal determinism", starting from automata for unranked trees in which the horizontal evaluation is performed by finite state automata. We show that a restriction to confluent horizontal evaluation leads to polynomial-time emptiness and universality, but still suffers from coNP-completeness of the emptiness of binary intersections. Finally, efficient algorithms can be obtained by imposing an order of horizontal evaluation globally for all automata in the class. Depending on the choice of the order, we obtain different classes of automata, each of which has the same expressiveness as CMso.

Institutions and Economic Growth:  How Institutional Change Triggers Divergence, Convergence, and Non-Zero Sums
Creators: Auriat, Scott
Publisher: name: University of Alberta Library
Year: 2022

The thesis explores the effect of institutional change on economic output. Chapters 1 and 2 are empirical and examine historical events. Chapter 1 makes the case that the Mongol Empire played a prominent role in the Industrial Revolution emerging in Western Europe. Western Europe developed democratic institutions that better supported economic growth because it was never successfully invaded by the Mongols. Chapter 2 uses the collapse of the USSR as a natural experiment and shows that the countries born from the collapse of the USSR that opted to join the European Union did better than the countries that did not. The paper makes the case that this was due to the market-focused institutions of the EU. Chapter 3 is a theoretical paper that develops a model elucidating the primary causes of the sudden jump in growth rates concurrent with the Industrial Revolution using game theory. The idea is that good institutions shift the payoffs to engaging in cooperative endeavors such as trade.

description: Are spinodal instabilities the leading mechanism in the fragmentation of a fermionic system? Numerous experimental indications suggest such a scenario and stimulated much effort in giving a suitable description, without being finalised in a dedicated transport model. On the one hand, the bulk character of spinodal behaviour requires an accurate treatment of the one-body dynamics, in presence of mechanical instabilities. On the other hand, pure mean-field implementations do not apply to situations where instabilities, bifurcations and chaos are present. The evolution of instabilities should be treated in a large-amplitude framework requiring fluctuations of Langevin type. We present new stochastic approaches constructed by requiring a thorough description of the mean-field response in presence of instabilities. Their particular relevance is an improved description of the spinodal fragmentation mechanism at the threshold, where the instability growth is frustrated by the mean-field resilience.

description: In der Schweiz werden die Möglichkeiten für das Publizieren in Diamond-OA derzeit ausgebaut: Die Universitätsbibliotheken stellen die Publikationsinfrastruktur zur Verfügung. Förderungsinstitutionen finanzieren den Ausbau der Infrastruktur, Akademien unterstützen Herausgeberschaften und übernehmen z.B. Hostinggebühren. Die nationale Open-Access-Strategie gibt eine gute Richtung vor, die Möglichkeiten zur Förderung des institutionellen Publizierens werden als mögliche Lösung explizit genannt. Europäische Projekte (z.B. DIAMAS) entwickeln Standards, Netzwerke, Tools und Infrastrukturen für institutionelles Diamond-OA-Publizieren.
 Die institutionellen Anbieterinnen von Publikationsdienstleistungen stehen allerdings vor verschiedenen Problemen. Zum einen sind sie mit rechtlichen Hindernissen und Beschränkungen konfrontiert; zum andern erschweren die Konzepte der konkreten Publikationsförderung den Institutionen den Ausbau der Diamond-OA-Angebote, denn die Förderung ist derzeit hauptsächlich auf das APC-Modell der Verlage ausgerichtet. Institutionelle Publikationsangebote passen nicht in die derzeitigen Förderungsmechanismen für Publikationen und werden deshalb von der Forschungsförderung vorerst nicht unterstützt.
 Die Weichen für eine stabile Diamond-OA-Landschaft müssen jetzt gestellt werden, sonst droht die Gefahr, dass sich auch hier kostspielige Geschäftsmodelle etablieren, die der Forschung Mittel entziehen.
 Unser Vortrag zeigt aus der Perspektive einer Universitätsbibliothek die Reibungen in der entstehenden Schweizer Diamond-OA-Landschaft auf. Die Problematik wird anhand von Beispielen aus unserer Publikationspraxis auf den Plattformen BOP Serials und BOP Books illustriert.
 Wir präsentieren drei Lösungsansätze, die über Kollaborationen eine stabile Alternative zu den gegenwärtigen Modellen der Publikations- bzw. Verlagsförderung möglich machen: Infrastruktur und Tools, die die Produktion finanziell und administrativ erleichtern; neue Finanzierungswege, die die Nachhaltigkeit unterstützen; Netzwerklösungen, um den rechtlichen Spielraum zu erweitern.

description: We present a way of exciting surface plasmon polaritons along non-patterned metallic surfaces by means of a flat squeezing slab designed with transformation optics. The slab changes the dispersion relation of incident light, enabling evanescent coupling to propagating surface plasmons. Unlike prism couplers, the proposed device does not introduce reflections at its input interface. Moreover, its compact geometry is suitable for integration. A feasible dielectric implementation of the coupler is suggested. Finally, we show that the angular response of the device can be engineered by using a non-uniform compression factor. As an example, we design a coupler with a half-power angular bandwidth 2.5 times higher than that of a conventional dielectric coupler.

Journeying Through Sport with Self-Compassion: Athlete Narratives of Navigating Pressure and Struggle
Creators: Frentz, Danae M.
Publisher: name: University of Alberta Library
Year: 2022

In high-level sport, there is often an overemphasis on performance which can lead to a decline in athletes’ physical health, mental well-being, and quality of life (Douglas & Carless, 2009; Smith, 2010). Development of adaptive coping resources, such as self-compassion, may help mitigate threats to well-being (Mosewich, Ferguson, et al., 2019). The purpose of this study was to explore how women athletes high in self-compassion story their journey through sport as well as their experiences of navigating pressure and struggle. Three women athletes high in self-compassion were invited to take part in two loosely structured one-on-one interviews, as part of a narrative approach to learn about their sport careers, stories, and experiences (Riessman, 2008). Both narrative thematic and structural analyses were undertaken to help capture the rich descriptions of athletes’ experiences as well as the overarching structure of their narrative accounts. Each athlete narrative greatly deviated from the narrative of performance, which is typically a dominant narrative in sport (Douglas & Carless, 2006). Specifically, athletes’ shared narratives of Rediscovery, Balance, and Redefining. Additionally, instead of being consumed by performance, these athletes demonstrated an active desire to invest in other aspects of their lives such as key relationships and future career aspirations. Such findings suggest the presence of counter-stories or alternative narratives that may assist future athletes in storying their lives in more meaningful ways. By exploring how self-compassionate athletes story their experiences, we can glean valuable information regarding the language they use to describe and apply self-compassion within sport. These findings can help tailor practical applications of self-compassion among athlete populations.

Modelling the Atlantic Water along its poleward pathway into and through the Arctic Ocean
Creators: Fu, Chuanshuai
Publisher: name: University of Alberta Library
Year: 2022

The thermohaline intrusion of the warm and saline Atlantic Water (AW) into the Arctic Ocean, referred to as “Arctic Atlantification”, has significant implications and feedback on the {thermo}dynamics of the Arctic Ocean. The AW enters the Arctic Ocean through two gateways:  Fram Strait and the Barents Sea Opening (BSO), and the relative strength of these two AW branches dominates the oceanic heat contribution to the Arctic Ocean. In conjunction with the measurements in key hydrographic sections, numerical ocean modelling provides us with a useful tool to characterize and corroborate the temporal and spatial variability of the AW branches. The simulations are carried out using the regional configuration the Arctic and North Hemispheric Atlantic (ANHA) of the ocean/sea-ice model NEMO running at 1/4° and 1/12° high resolutions. Online passive tracers from the model configurations are used to trace the pathways of the AW inflow in the Arctic Ocean.

With the AW becoming more important to the dynamics of the Arctic Ocean, this study aims to examine its variability, transformation, and impacts, as well as ultimately track how it evolves. We first evaluate the interannual and seasonal variability of the AW thermohaline structure at these two gateways, then quantify the AW volume and heat transport on the interannual and seasonal timescales. We also compare long-term transport means with the available observations. While the heat in the Fram Strait Branch Water (FSBW) dissipates in a slower process through the mixing with the ambient cold water below the sea surface, the vast majority of the heat loss of the Barents Sea Branch Water (BSBW) takes place in the Barents Sea due to the sea surface cooling. In our study, we discover two strong Cold AW anomaly events along the rim of the eastern Eurasian Basin during 2013 and 2014, overturning our understanding that the AW is always warm and saline. The dominant contributor to the Cold AW formation is the intense sea surface cooling at the Barents Sea for two consecutive years. By releasing particles at the Barents Sea Opening and Fram Strait using an offline Lagrangian product Ariane, we find that the source of the Cold AW is primarily from the BSBW, and it also has some contributions from the FSBW. The Cold AW signals progress along the typical AW poleward pathway and eventually result in a heat content reduction in the AW layer of the eastern Arctic Basin.

description: The Joint Automated Repository for Various Integrated Simulations (JARVIS) infrastructure at the National Institute of Standards and Technology (NIST) is a large-scale collection of curated datasets and tools with more than 80000 materials and millions of properties. JARVIS uses a combination of electronic structure, artificial intelligence (AI), advanced computation and experimental methods to accelerate materials design. Here we report some of the new features that were recently included in the infrastructure such as: 1) doubling the number of materials in the database since its first release, 2) including more accurate electronic structure methods such as Quantum Monte Carlo, 3) including graph neural network-based materials design, 4) development of unified force-field, 5) development of a universal tight-binding model, 6) addition of computer-vision tools for advanced microscopy applications, 7) development of a natural language processing tool for text-generation and analysis, 8) debuting a large-scale benchmarking endeavor, 9) including quantum computing algorithms for solids, 10) integrating several experimental datasets and 11) staging several community engagement and outreach events. New classes of materials, properties, and workflows added to the database include superconductors, two-dimensional (2D) magnets, magnetic topological materials, metal-organic frameworks, defects, and interface systems. The rich and reliable datasets, tools, documentation, and tutorials make JARVIS a unique platform for modern materials design. JARVIS ensures openness of data and tools to enhance reproducibility and transparency and to promote a healthy and collaborative scientific environment.
The difference cross sections of unpolarized SIDIS with transverse momentum dependence

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: Previously we showed that, based only on C and SU(2) invariance, the difference cross sections of hadrons with opposite charge in SIDIS e+N\to l+h+X is expressed solely in terms of the valence-quark densities and certain non-singlet combinations of FFs. This allowed to determine these quantities in a model independent way. Now we extend this approach to processes when the transverse momentum of the final hadron is measured as well. We show that the difference cross sections of unpolarized SIDIS on proton and deuterium targets, d\s_N^{h^+-h^-}, d\s_N^{π^+-π^-} and d\s_N^{K^+-K^-}, are expressed solely in terms of the TMD unpolarized valence quark densities and FFs, and the valence-quark Boer-Mulders and Collins functions. This allows to determine them separately and study flavour dependence of the quark transverse momentum. Measurements on deuterium target, d\s_d^{h^+-h^-}, d\s_d^{π^+-π^-} and d\s_d^{K^+-K^-}, provide 3 independent measurements for the sum of the TMD valence quark densities and Boer-Mulders functions: (u_{1,V}+d_{1,V}) and (h_{1,uV}^\perp + h_{1,dV}^\perp).

description: Recent developments in the Philippines have placed the country in the middle of a Sino-American great power rivalry. In June 2024, tensions flared between China and the Philippines in the South China Sea (SCS) when pictures came out of the Chinese Coast Guard threatening Filipino crew with knives and spears near the Second Thomas Shoal. These actions, together with the latest assertiveness of China in the region have led to concerns towards the possibility of armed conflict. Meanwhile, the Philippines has been enhancing its defense partnership with the US, deepening scopes for military usage and staging joint drills.
A comparison of coarse woody debris in post-harvest and post-fire island remnants a decade after disturbance in northern Alberta
Creators: Moore, Lance Parker
Publisher: name: University of Alberta Library
Year: 2022

Retention forestry is the practice of retaining forest structure within cut-blocks at harvest sites and is practiced widely throughout the world. Although retention practices are modelled on the propensity for fires to leave behind a variety of biological legacies or structural elements, the comparison of post-fire and post-harvest residual forest structure has received little attention. Coarse woody debris is an important component of forest structure often influenced by management. I, thus, compared coarse woody debris attributes in residual patches in harvested areas and wildfire disturbed areas to determine how coarse woody debris was influenced by the different disturbances. During the spring of 2021, 30 sites (15 harvest and 15 fire) were selected that experienced a harvest or fire between the years of 2009-2011.

Overall, coarse woody debris attributes were similar between fire sites and harvest sites. The coarse woody debris volume of early decayed wood (decay class 1 and 2) for fire islands had an average volume of 42 m3/ha; meanwhile, harvest islands averaged 31 m3/ha. The initial stand volume for both disturbance types in references and islands varied between 300-400 m3/ha and was not an important predictor of coarse woody debris volumes. Distributions of size classes in both islands and references were similar in fire and harvest disturbance types. This study found no evidence to support that edge and interior plots varied amongst each other or between disturbance types. The variability amongst the fires and the harvests surveyed was low and did not influence coarse woody debris attributes. Overall, a decade after disturbance, fire residuals and retention patches were found to be similar with respect to coarse woody debris attributes. This implies the long-term effectiveness of aggregate retention in ecosystem based management strategies on coarse woody debris volume and attributes within the mixedwood boreal forests of northern Alberta.
Wavelet based modeling of subgrid-scales in LES of particle-laden turbulent flows

description: We propose a novel model to obtain the subgrid-scale velocity in the context of large-eddy simulation (LES) of particle-laden turbulent flows, to recover accurate particle statistics. In the new wavelet enrichment model, the subgrid-scale velocity is discretized with a divergence-free wavelet vector basis, and the coefficients of the expansion are obtained by minimizing the squared error of the linearized subfilter Navier-Stokes equations (SFNSE). The compact support of the wavelet basis is exploited to achieve continuously varying subgrid-scale velocity statistics across the domain. The performance of the new wavelet enrichment model is evaluated in single-phase and particle-laden flow simulations, comparing the results with the results of direct numerical simulations (DNS). The simulations show that the model can generate inhomogeneous and anisotropic velocity statistics, accurate strain-rotation relations, and a good approximation of the kinetic energy spectrum of the corresponding DNS. Furthermore, the model significantly improves the prediction of the particle-pair dispersion, the clustering of the particles, and the turbulence modulation by particles in two-way coupled simulations. The proposed model recovers the most important interactions between fluid turbulence and the behavior of the particles, while maintaining the computational cost on the order of a LES.

description: It is well known that the first structures that form from small fluctuations in a self-gravitating, collisionless and initially smooth cold dark matter (CDM) fluid are pancakes. We study the gravitational force generated by such pancakes just after shell-crossing, and find a simple analytical formula for the force along the collapse direction, which can be applied to both the single- and multi-stream regimes. The formula is tested on the early growth of CDM protohaloes seeded by two or three crossed sine waves. Adopting the high-order Lagrangian perturbation theory (LPT) solution as a proxy for the dynamics, we confirm that our analytical prediction agrees well with the exact solution computed by direct resolution of the Poisson equation, as long as the caustic structure remains locally sufficiently one-dimensional. These results are further confirmed by comparisons of the LPT predictions performed this way to measurements in Vlasov simulations performed with the public code ColDICE. We also show that the component of the force orthogonal to the collapse direction preserves its single stream nature by not changing qualitatively before and after the collapse, allowing sufficiently high-order LPT acceleration to be used to approximate it accurately as long as the LPT series converges. As expected, solving Poisson equation on the density field generated with LPT displacement provides a more accurate force than the LPT acceleration itself, as a direct consequence of the faster convergence of the LPT series for the positions than for the accelerations. This may provide a clue on improving standard LPT predictions. Our investigations represent a very needed first step to study analytically gravitational dynamics in the multi-stream regime, by estimating, at leading order in time and space the proper backreaction on the gravitational field inside the pancakes.

description: There has been a growing interest in defining models of automata enriched with time. For instance, timed automata were introduced as automata extended with clocks. In this paper, we study models of timed finite state machines (TFSMs), i.e., FSMs enriched with time, which accept timed input words and generate timed output words. Here we discuss some models of TFSMs with a single clock: TFSMs with timed guards, TFSMs with timeouts, and TFSMs with both timed guards and timeouts. We solve the problem of equivalence checking for all three models, and we compare their expressive power, characterizing subclasses of TFSMs with timed guards and of TFSMs with timeouts that are equivalent to each other.

description: City centers have to cope with an increasing amount of air pollution. The supply of fresh air is crucial yet difficult to ensure, especially under stable conditions of the atmospheric boundary layer. This case study used the PArallelized Large eddy simulation (LES) Model PALM to investigate the wind field over an urban lake that had once been built as a designated fresh air corridor for the city center of Münster, northwest, Germany. The model initialization was performed using the main wind direction and stable boundary layer conditions as input. The initial wind and temperature profiles included a weak nocturnal low-level jet. By emitting a passive scalar at one point on top of a bridge, the dispersion of fresh air could be traced over the lake’s surface, within street canyons leading to the city center and within the urban boundary layer above. The concept of city ventilation was confirmed in principle, but the air took a direct route from the shore of the lake to the city center above a former river bed and its adjoining streets rather than through the street canyons. According to the dispersion of the passive scalar, half of the city center was supplied with fresh air originating from the lake. PALM proved to be a useful tool to study fresh air corridors under stable boundary layer conditions.

description: The world is full of fluids that flow. The fluid nature of flowing skyrmionic quasiparticles is of fundamental physical interest and plays an essential role in the transport of many skyrmions. Here, we report the laminar and transiently disordered dynamic behaviors of many magnetic skyrmions flowing in a pipe channel. The skyrmion flow driven by a uniform current may show a lattice structural transition. The skyrmion flow driven by a non-uniform current shows a dynamically varying lattice structure. A large uniform current could result in the compression of skyrmions toward the channel edge, leading to the transition of the skyrmion pipe flow into an open-channel flow with a free surface. Namely, the width of the skyrmion flow could be adjusted by the driving current. Skyrmions on the free surface may form a single shear layer adjacent to the main skyrmion flow. In addition, although we focus on the skyrmion flow dynamics in a clean pipe channel without any pinning or defect effect, we also show that a variation of magnetic anisotropy in the pipe channel could lead to more complicated skyrmion flow dynamics and pathlines. Our results reveal the fluid nature of skyrmionic quasiparticles that may motivate future research on the complex flow physics of magnetic textures.

Longitudinal Diffusion-Weighted Imaging and T2 Relaxometry of the Hippocampus in Temporal Lobe Epilepsy
Creators: Adel, Seyed Amir Ali
Publisher: name: University of Alberta Library
Year: 2022

Hippocampal sclerosis (HS) is an important predictor of surgical outcome in temporal lobe epilepsy (TLE). High-resolution (1 mm isotropic) diffusion tensor imaging (DTI) of the hippocampus in TLE patients has shown patterns of hippocampal subfield diffusion abnormalities which were consistent with HS subtype on surgical histology in a pilot sample of four patients. T2 relaxometry has also demonstrated focal hippocampal abnormalities which correlated with HS pathological features of neuron loss, gliosis, and granule cell dispersion. The objectives of this thesis were to determine the stability of focal hippocampus diffusion changes over time in TLE patients, compare diffusion and quantitative T2 abnormalities of the sclerotic hippocampus and correlate pre-surgical mean diffusivity (MD) and T2 maps with post-surgical histology.

To address these objectives, 19 TLE patients and 19 controls underwent two high-resolution (1 × 1 × 1 mm3) DTI and (1.1 × 1.1 × 1 mm3) T2 relaxometry scans (in a subset of 16 TLE patients and 9 controls) of the hippocampus at 3T, with a 2.6±0.8 year inter-scan interval. Within-participant hippocampal volume, MD and T2 were compared between the scans. Contralateral hippocampal changes 2.3±1.0 years after surgery and ipsilateral pre-operative MD maps versus post-operative subfield histopathology were evaluated in 8 patients who underwent surgical resection of the hippocampus.

The results showed significantly reduced volume and elevated MD and T2 of sclerotic hippocampi compared to healthy and non-HS hippocampi. These whole-hippocampus measures remained unchanged between the longitudinal scans. Focal regions of elevated MD and T2 in bilateral hippocampi of HS TLE were detected consistently at both scans. Regions of high MD and T2 correlated and remained consistent over time. Volume, MD and T2 remained unchanged in post-operative contralateral hippocampus. Regional elevations of MD identified subfield neuron loss on post-surgical histology with 88% sensitivity and 88% specificity. Focal T2 elevations identified subfield neuron loss with 75% sensitivity and 88% specificity.

The findings of this work suggest no significant change in diffusion and T2 abnormalities in ipsilateral and contralateral hippocampi between the two scans, suggesting permanent micro-structural alterations. While both MD and T2 accurately predicted HS subtypes, MD was more sensitive than T2 in detecting neuron loss on post-surgical histology. Both DTI and T2 acquisitions were acquired using a clinically feasible protocol (at 3T in under 6 minutes each), potentially providing the opportunity to diagnose precise HS subtypes as well as detect subtle or regional contralateral hippocampal abnormalities, which may aide in predicting surgical outcomes preoperatively.
This "court of mine" : an analysis of Black women athletes media use as a tool for advocacy, self-care, and activism

description: This paper considers the ways in which Black women athletes have used media to disrupt and challenge dominant narratives and images about themselves. Black women- in and out of sports- have long been scrutinized and subjugated by media narratives and stereotypical images. Yet, in recent years, Black women in sports have found ways to successfully use their platforms and media engagement to offer counter narratives about their athletic participation. This paper uses media discourse analysis and Black feminist thought to examine six contemporary major professional Black women athletes and their personal uses of media. Ultimately, this study reveals how Black women have been able to use new forms of media engagement as tools for advocacy and activism, challenging racialized and gendered stereotypes while simultaneously addressing issues like self-care, mental health and wellness and political protest.

description: Recently, the out-of-time-ordered correlator (OTOC) has gained much attention as an indicator of quantum chaos. In the semi-classical limit, its exponential growth rate resembles the classical Lyapunov exponent. The quantum-classical correspondence has been supported for the one-body chaotic systems as well as realistic systems with interactions, as in the Dicke model, a model of multi-two-level atoms and cavity field interactions. To this end, we calculate the OTOC for different variations of the Dicke model in an open quantum system setting. The connection between the superradiant phase transition of the Dicke model and the OTOC is studied. Further, we establish a relation between the OTOC and the second-order coherence function. This becomes important for the experimental studies of the OTOC and quantum chaos in the models of quantum optics.
