description: We give definitions of moduli spaces of framed, r-Spin and Pin surfaces. We apply earlier work of the author to show that each of these moduli spaces exhibits homological stability, and we identify the stable integral homology with that of certain infinite loop spaces in each case. We further show that these moduli spaces each have path components which are Eilenberg--MacLane spaces for the framed, r-Spin and Pin mapping class groups respectively, and hence we also identify the stable group homology of these groups. In particular: the stable framed mapping class group has trivial rational homology, and its abelianisation is Z/24; the rational homology of the stable Pin mapping class groups coincides with that of the non-orientable mapping class group, and their abelianisations are Z/2 for Pin^+ and (Z/2)^3 for Pin^-.

description: The Cherenkov Telescope Array (CTA) Observatory, with dozens of telescopes located in both the Northern and Southern Hemispheres, will be the largest ground-based gamma-ray observatory and will provide broad energy coverage from 20 GeV to 300 TeV. The large effective area and field-of-view, coupled with the fast slewing capability and unprecedented sensitivity, make CTA a crucial instrument for the future of ground-based gamma-ray astronomy. To maximise the scientific return, the array will send alerts on transients and variable phenomena (e.g. gamma-ray burst, active galactic nuclei, gamma-ray binaries, serendipitous sources). Rapid and effective communication to the community requires a reliable and automated system to detect and issue candidate science alerts. This automation will be accomplished by the Science Alert Generation (SAG) pipeline, a key system of the CTA Observatory. SAG is part of the Array Control and Data Acquisition (ACADA) working group. The SAG working group develops the pipelines to perform data reconstruction, data quality monitoring, science monitoring and real-time alert issuing during observations to the Transients Handler functionality of ACADA. SAG is the system that performs the first real-time scientific analysis after the data acquisition. The system performs analysis on multiple time scales (from seconds to hours). \abrb{SAG must issue candidate science alerts within} 20 seconds from the data taking and with sensitivity at least half of the CTA nominal sensitivity. These challenging requirements must be fulfilled by managing trigger rates of tens of kHz from the arrays. Dedicated and highly optimised software and hardware architecture must thus be designed and tested. In this work, we present the general architecture of the ACADA-SAG system.

description: In this report, we develop a semistability analysis framework for nonlinear systems with bounded time-varying delays with applications to stability analysis of multiagent dynamic networks with consensus protocols in the presence of unknown heterogeneous time-varying delays along the communication links. We show that for such a nonlinear system having nonisolated equilibria, if the system asymptotically converges to a constant time-delay system and this new system is semistable, then the original time-varying delay system is semistable. In proving our results, we extend the limiting differential equation approach to time-varying delay systems and also develop some new convergence results for functional differential equations.

description: By moving the pivot of a pendulum rapidly up and down one can create a stable position with the pendulum's bob above the pivot rather than below it. This surprising and counterintuitive phenomenon is a widespread feature of driven systems and carries over into the quantum world. Even when the static properties of a quantum system are known, its response to an explicitly time-dependent variation of its parameters may be highly nontrivial, and qualitatively new states can appear that were absent in the original system. In quantum mechanics the archetype for this kind of behaviour is an atom in a radiation field, which exhibits a number of fundamental phenomena such as the modification of its g-factor in a radio-frequency field and the dipole force acting on an atom moving in a spatially varying light field. These effects can be successfully described in the so-called dressed atom picture. Here we show that the concept of dressing can also be applied to macroscopic matter waves, and that the quantum states of "dressed matter waves" can be coherently controlled. In our experiments we use Bose-Einstein condensates in driven optical lattices and demonstrate that the many-body state of this system can be adiabatically and reversibly changed between a superfluid and a Mott insulating state by varying the amplitude of the driving. Our setup represents a versatile testing ground for driven quantum systems, and our results indicate the direction towards new quantum control schemes for matter waves.

description: We study the evolution of extremely metal-poor AGB stars, with metallicities down to [Fe/H]=-5, to understand the main evolutionary properties, the efficiency of the processes able to alter their surface chemical composition and to determine the gas and dust yields. We calculate two sets of evolutionary sequences of stars in the 1-7.5Msun mass range, evolved from the pre-main sequence to the end of the AGB phase. To explore the extremely metal-poor chemistries we adopted the metallicities Z=3x10^{-5} and Z=3x10^{-7} which correspond, respectively to [Fe/H]=-3 and [Fe/H]=-5. The results from stellar evolution modelling are used to calculate the yields of the individual chemical species. We also modelled dust formation in the wind, to determine the dust produced by these objects. The evolution of AGB stars in the extremely metal-poor domain explored here proves tremendously sensitive to the initial mass of the star. M<2Msun stars experience several third dredge-up events, which favour the gradual surface enrichment of C12 and the formation of significant quantities of carbonaceous dust, of the order of 0.01Msun. The C13 and nitrogen yiel are found to be significantly smaller than in previous explorations of low-mass, metal-poor AGB stars, owing to the weaker proton ingestion episodes experienced during the initial AGB phases. M>5Msun stars experience hot bottom burning and their surface chemistry reflects the equilibria of a very advanced proton-capture nucleosynthesis; little dust production takes place in their wind. Intermediate mass stars experience both third dredge-up and hot bottom burning: they prove efficient producers of nitrogen, which is formed by proton captures on C12 nuclei of primary origin dredged-up from the internal regions.

description: Iron oxide is one of the most important components in Earth's mantle. Recent discovery of the stable presence of Fe5O6 at Earth's mantle environment stimulates significant interests in the understanding of this new category of iron oxides. In this paper, we report the electronic structure and magnetic properties of Fe5O6 calculated by the density functional theory plus dynamic mean field theory (DFT+DMFT) approach. Our calculations indicate that Fe5O6 is a conductor at the ambient pressure with dominant Fe-3d density of states at the Fermi level. The magnetic moments of iron atoms at three non-equivalent crystallographic sites in Fe5O6 collapse at significantly different rate under pressure. Such site-selective collapse of magnetic moments originates from the shifting of energy levels and the consequent charge transfer among the Fe-3d orbits when Fe5O6 is being compressed. Our simulations suggest that there could be high conductivity and volume contraction in Fe5O6 at high pressure, which may induce anomalous features in seismic velocity, energy exchange, and mass distribution at the deep interior of Earth.

Building on the extensive research that has been conducted on folk antagonists born on the internet such as the Slenderman, I will discuss another character named Momo who, according to legend, lead their primarily young followers through a series of self-inflicted, harmful acts, each increasing in severity, with the final act ultimately being the taking of one’s life. Research will examine social media threads, YouTube videos, film/television, and fan fiction to unpack the "who, what, how" of the culture's primary participants, and what non-participants stand to gain from understanding its implications.

description: For many years structural mineralogists have found Pauling’s concept of bond strength or bond valence a useful tool in evaluating mineral structures. This is a powerful approach to predict the structure and properties of materials. Bond valences determined from experimentally measured bond lengths are used to calculate atomic valences which can be used to help in determination and evaluation of crystal structures. This method was used to determine the crystal structure of La(Ti1/2Zn1/2)O3 (LZT) and Nd((Ti1/2Zn1/2)O3 (NZT). The result indicates that LZT has monoclinic crystal structure. Nd+3 has much smaller ionic polarisability (5.01 Å) than La+3 (6.03 Å). The explanation for the increase can be attributed to the smaller size of Nd+3(1.27 Å) cation compared to La+3(1.36 Å), which increase the number of dipoles per unit volume and thus inflates r H despite the reduction in polarisability.

title: A Tale of Two Sandals: Analysis of Two Sandals from the Gordon Keller Collection
Creators: name: Morris-Larsen, Emily
Publisher: name: Utah State University
Year: 2020

description: This paper presents a comparative analysis of sandals from the Utah State University Museum of Anthropology Gordon Keller collection. The sandals were recovered by Dr. Gordon Keller during fieldwork in southeastern Utah. Through a discussion and analysis of sandal styles and their temporal reaches, how these sandals relate to known specimens and greater Desert West sandal trends is uncovered. One sandal is a plaited vegetable fiber sandal, believed to be yucca. Pending radiocarbon analysis, stylistically the sandal appears to date to approximately 1200 AD. The second is a pair of unusual leather hide sandals, constructed in a shape more common to vegetable fiber square-toe-square heel sandals than to other leather footwear, such as the Promontory Point Moccasins or Fremont moccasins. Based on the style, it is believed to come from the periphery of the Colorado Plateau and date somewhere between 1350 AD to 1540 AD.

description: We present SP-GAN, a new unsupervised sphere-guided generative model for direct synthesis of 3D shapes in the form of point clouds. Compared with existing models, SP-GAN is able to synthesize diverse and high-quality shapes with fine details and promote controllability for part-aware shape generation and manipulation, yet trainable without any parts annotations. In SP-GAN, we incorporate a global prior (uniform points on a sphere) to spatially guide the generative process and attach a local prior (a random latent code) to each sphere point to provide local details. The key insight in our design is to disentangle the complex 3D shape generation task into a global shape modeling and a local structure adjustment, to ease the learning process and enhance the shape generation quality. Also, our model forms an implicit dense correspondence between the sphere points and points in every generated shape, enabling various forms of structure-aware shape manipulations such as part editing, part-wise shape interpolation, and multi-shape part composition, etc., beyond the existing generative models. Experimental results, which include both visual and quantitative evaluations, demonstrate that our model is able to synthesize diverse point clouds with fine details and less noise, as compared with the state-of-the-art models.

description: This paper describes the design process of a torque sensor, which is structurally integrated into the kinematic chain of an assistive upper limb exoskeleton to measure user interaction. Two different approaches of torque sensor integration are discussed regarding the nominal torque loads on each joint and applied transverse stresses. The final sensor concept consists of an aluminum spoke wheel deformation element with four strain gauges connected to a Wheatstone bridge. It is mounted between the motor casing and gear drive of each joint to measure the torque of the actuator and user. A sensor electronics board including signal processing and an EtherCAT interface is integrated in each joint. The torque sensor shows linear transmission characteristics for 0.4 Nm nominal rated torque with a linear error of 0.51 % and a hysteresis error of 0.53 %.

description: Allies Training Programs (also known as Safe Space/Zone training) are found in many institutions of higher education. Usually provided by an LGBTQA+ or Gender and Sexuality Center staff, the goal is to prepare participants for an allyship role in hopes of promoting safe spaces on campus and decrease instances of queerphobia. This thesis examined current allies training programs to determine what content is being presented and compare to the latest critiques and definitions. After analysis it is determined that current allyship trainings are inadequately preparing higher education staff and faculty for an ally role. Using the results of this study and the works of other scholars, I offer a new approach to allyship training programs through a suggested online curriculum geared toward higher education staff and faculty.

description: We infer from different seismic observations the energy supplied per unit of time by turbulent convection to the acoustic modes of Alpha Cen A (HD 128620), a star which is similar but not identical to the Sun. The inferred rates of energy supplied to the modes (i.e. mode excitation rates) are found to be significantly larger than in the Sun. They are compared with those computed with an excitation model that includes two sources of driving, the Reynolds stress contribution and the advection of entropy fluctuations. The model also uses a closure model, the Closure Model with Plumes (CMP hereafter), that takes the asymmetry between the up- and down-flows (i.e. the granules and plumes, respectively) into account. Different prescriptions for the eddy-time correlation function are also confronted to observational data. Calculations based on a Gaussian eddy-time correlation underestimate excitation rates compared with the values derived from observations for Alpha Cen A. On the other hand, calculations based on a Lorentzian eddy-time correlation lie within the observational error bars. This confirms results obtained in the solar case. With respect to the helioseismic data, those obtained for Alpha Cen A constitute an additional support for our model of excitation. We show that mode masses must be computed taking turbulent pressure into account. Finally, we emphasize the need for more accurate seismic measurements in order to discriminate, in the case of Alpha Cen A, between the CMP closure model and the quasi-Normal Approximation as well as to confirm or not the need to include the excitation by the entropy fluctuations.

description: We investigate vibration modes and their Raman activity of single-walled carbon nanotubes that are bent within their intrinsic elastic limits. By implementing novel boundary conditions for density-functional based tight-binding, and using non-resonant bond polarization theory, we discover that Raman activity can be induced by bending. Depending on the degree of bending, high-energy Raman peaks change their positions and intensities significantly. These effects can be explained by migration of nodes and antinodes along tube circumference. We discuss the challenge of associating the predicted spectral changes with experimental observations.

description: The median eminence (ME), located at the base of the hypothalamus, is an essential centre of information exchange between the brain and the pituitary. We and others previously showed that mutations and duplications affecting the transcription factor SOX3/Sox3 result in hypopituitarism, and this is likely of hypothalamic origin. We demonstrate here that the absence of Sox3 predominantly affects the ME with phenotypes that first occur in juvenile animals, despite the embryonic onset of SOX3 expression. In the pituitary, reduction in hormone levels correlates with a lack of endocrine cell maturation. In parallel, ME NG2-glia renewal and oligodendrocytic differentiation potential are affected. We further show that low-dose aspirin treatment, which is known to affect NG2-glia, or changes in gut microbiota, rescue both proliferative defects and hypopituitarism in Sox3 mutants. Our study highlights a central role of NG2-glia for ME function during a transitional period of post-natal development and indicates their sensitivity to extrinsic signals.

Our approach utilizes the same fan structure of the variety but deforms the underlying embedded algebraic torus. We develop a sheaf theory using techniques from noncommutative algebraic geometry. The cases of projective varieties are studied in detail, and several explicit examples are worked out, including new noncommutative deformations of Grassmann and flag varieties. Our constructions set up the basic ingredients for thorough study of instantons on noncommutative toric varieties, which will be the subject of the sequel to this paper.

description: This paper introduces a run-and-tumble model with self-reinforcing directionality and rests. We derive a single governing hyperbolic partial differential equation for the probability density of random walk position, from which we obtain the second moment in the long time limit. We find the criteria for the transition between superdiffusion and diffusion caused by the addition of a rest state. The emergence of superdiffusion depends on both the parameter representing the strength of self-reinforcement and the ratio between mean running and resting times. The mean running time must be at least $2/3$ of the mean resting time for superdiffusion to be possible. Monte Carlo simulations validate this theoretical result. This work demonstrates the possibility of extending the telegrapher's (or Cattaneo) equation by adding self-reinforcing directionality so that superdiffusion occurs even when rests are introduced.
title: Effects of Flow Path Factors in the Permeability of Natural and Man-made Granular Soils Using the Kozeny-Carman Equation
Creators: name: Davies, Robert
Publisher: name: Utah State University
Year: 2021

description: The research presented in this paper serves to observe how the flow path factors relate to the void ratio, the effective diameter of a soil particle, and the permeability of a given sample assuming the behavior is consistent across natural and artificial soils. The basis of the comparison is the derived Kozeny-Carman Equation for permeability with focus on the factors Cs and Cl where Cs represents the shape of the flow path and Cl represents the length of the flow path that a single water molecule must travel through a soil sample. Permeameter tests were conducted for six types of material including three natural sands and two man-made samples to compare data. Man-made or unnatural samples included stainless steel pins and ceramic spheres. Four other natural sands were tested at both 50% and 90% relative density to compare data. Natural sands included C33 sand, Quartz sand, Fine Ottawa sand and Coarse Ottawa sand. It was observed that while the permeability of the samples was impacted by the geometry of the flow paths, as shown in the flow path factors CsCl, as well as the void ratios, it appears that the effective diameter Ds has a larger impact on permeability.

description: Our lab, and others, have recently demonstrated that fear behavior can be weakened following training with a footshock by presenting a weaker version of that footshock (a phenomenon termed ‘unconditional stimulus deflation’ or US deflation). Unlike extinction, US deflation likely functions by modifying the original fear memory potentially making it a more effective candidate for reducing fear and preventing relapse effects often observed following extinction. Here, we adapted our US deflation procedure to a delay conditioning paradigm in order to examine renewal, spontaneous recovery, and reinstatement. We found that while ABA renewal and reinstatement were unaffected by US deflation, spontaneous recovery and AAB renewal were reduced by US deflation. Deflation in the absence of a CS was ineffective at reducing behavior. Our results suggest that prevention of relapse is at least partially dependent on deflation occurring in the either the same context as training or testing when using a delay fear conditioning procedure.

title: Personal Identity and the Influence of Outlaw Folklore
Creators: name: Nivison, William "Bacon"
Publisher: name: Utah State University

description: Folklore being a relatively new science there is still debate going on about what Folklore actually is. Most of what one reads is relative to who the “folk” are, where the “lore” comes from and how it is inspired. This thesis looks at folkore from a viewpoint which observes folklore from the other direction. Not how do the folk create the lore, rather how does the lore create the folk?
Folklore is well shown to be a product, or at least an abstract of one’s personal identity, but, is it not also a tool used by the individual in the creation of an identity that the individual wishes to relate to others, “outsiders.” I grew up in a family situation which had its roots in two almost diametrically opposed ideologies, having in common only the prospective “good” either if these identities could be seen to promote. A religious family married into an outlaw family. The family folklore painted a magnificently broad stroke on what could be considered good, or heroic, but the outlaw folklore ended up carrying the day.
Based on input from three generations of this tribe, I examine how their stories are formed, interpreted, and used to magnify the three differing individualities involved. There is a strong similarity between the folkloric evolution of outlaws into heroes, and the adoption of seeds from these heroic outlaw tales in the creation of personal identities.

description: We work out the phase-space structure for a system of $n$ qubits. We replace the field of real numbers that label the axes of the continuous phase space by the finite field $\Gal{2^n}$ and investigate the geometrical structures compatible with the notion of unbiasedness. These consist of bundles of discrete curves intersecting only at the origin and satisfying certain additional properties. We provide a simple classification of such curves and study in detail the four- and eight-dimensional cases, analyzing also the effect of local transformations. In this way, we provide a comprehensive phase-space approach to the construction of mutually unbiased bases for $n$ qubits.

description: We report a $^{73}$Ge nuclear-quadrupole-resonance (NQR) study on novel evolution of unconventional superconductivity in antiferromagnetic (AFM) CeNiGe$_3$. The measurements of the $^{73}$Ge-NQR spectrum and the nuclear spin-lattice relaxation rate ($1/T_1$) have revealed that the unconventional superconductivity evolves inside a commensurate AFM phase around the pressure ($P$) where Néel temperature $T_{\rm N}$ exhibits its maximum at 8.5 K. The superconducting transition temperature $T_{\rm SC}$ has been found to be enhanced with increasing $T_{\rm N}$, before reaching the quantum critical point at which the AFM order collapses. Above $T_{\rm SC}$, the AFM structure transits from an incommensurate spin-density-wave order to a commensurate AFM order at $T\sim 2$ K, accompanied by a longitudinal spin-density fluctuation. With regard to heavy-fermion compounds, these novel phenomena have hitherto never been reported in the $P$-$T$ phase diagram.

title: A Review of Harmful Algal Bloom Prediction Models for Lakes and Reservoirs
Creators: name: Echard, Jade Snyder
Publisher: name: Utah State University
Year: 2021

description: Anthropogenic activity has led to eutrophication in water bodies across the world. This eutrophication promotes blooms, cyanobacteria being among the most notorious bloom organisms. Cyanobacterial blooms (more commonly referred to as harmful algal blooms (HABs)) can devastate an ecosystem. Cyanobacteria are resilient microorganisms that have adapted to survive under a variety of conditions, often outcompeting other phytoplankton. Some species of cyanobacteria produce toxins that ward off predators. These toxins can negatively affect the health of the aquatic life, but also can impact animals and humans that drink or come in contact with these noxious waters. Although cyanotoxin’s effects on humans are not as well researched as the growth, behavior, and ecological niche of cyanobacteria, their health impacts are of large concern. It is important that research to mitigate and understand cyanobacterial blooms and cyanotoxin production continues. This project supports continued research by addressing an approach to collect and summarize published articles that focus on techniques and models to predict cyanobacterial blooms with the goal of understanding what research has been done to promote future work. The following report summarizes 34 articles from 2003 to 2020 that each describe a mechanistic or data driven model developed to predict the occurrence of cyanobacterial blooms or the presence of cyanotoxins in lakes or reservoirs with similar climates to Utah. These articles showed a shift from more mechanistic approaches to more data driven approaches with time. This resulted in a more individualistic approach to modeling, meaning that models are often produced for a single lake or reservoir and are not easily comparable to other models for different systems.
title: The Demographic Effect of Minimum Wage: Evidence from San Francisco County
Creators: name: Mehrabinia, Poorya
Publisher: name: Utah State University
Year: 2021

description: The minimum wage in San Francisco was increased from $6.75 to $8.5 per hour in November 2003. This was primarily aimed to improve low-income workers' well-being, especially racial and ethnic minorities. This paper conducts a difference-in-difference model using a synthetic control group for San Francisco, looking into a possible change in employees' demographic composition in the Accommodation & Food Services, and Manufacturing industries. The results indicate that the ratio of white employees increased significantly, suggesting that a labor-labor substitution happened in the following years of the minimum wage increase.
Photon-number selective group delay in cavity induced transparency

description: We show that the group velocity of a probe pulse in an ensemble of $Λ$-type atoms driven by a quantized cavity mode depends on the quantum state of the input probe pulse. In the strong-coupling regime of the atom-cavity system the probe group delay is photon number selective. This can be used to spatially separate the single photon from higher photon-number components of a few-photon probe pulse and thus to create a deterministic single-photon source.

A British Columbia fishing village
Creators: name: Miller, Philip Carl
Publisher: name: University of British Columbia
Year: 2010

description: The question of the relationship between society and environment was addressed through the study of a remote fishing village of seven hundred and fifty people. An interdisciplinary approach was adopted in which the demographic, economic and social aspects of the community were investigated. . The integration of the disciplinary perspectives was facilitated by simulation modeling. The population of the village had grown gradually in size since its inception, but a decline occurred in the 1960*s. The migration rate was correlated with declining fish harvests and was concomitant with the expansion of communications with urban centers. A turn-around in migration had recently developed supported by an influx of people from the southern cities. Fishing provided the majority of economic opportunity, followed in importance by logging. A survey was conducted to investigate the costs and revenues of the fishermen of the village. Diversification was found to characterize the local fleet and analysis showed that the rates of return on investment in the current year were egualized between vessel types. Social and cultural features were found to be closely linked to environmental variables. Seasonality in birth rates was related to the pattern of work, loads. Attitudes toward locality among high school youth were studied through a regional survey. The analysis confirmed the hypothesis that there was a greater preference among youth of the village for staying than was indicated in other resource towns of the north Vancouver Island district. A diversity of formal and informal organizations facilitated social integration, though factional divisions and attitude differences toward future development were present. In response to developmental pressures, a realignment of the traditional organizations to focus on regional issues concerned with land and marine resources was taking place. The variable levels and rate parameters of the demographic, economic and social components of the model were specified using static and time series data. Sensitivity analysis to assess the effects of uncertainty, and validation tests against known historical changes were conducted. Forecast scenarios identified the development options under several levels of fish abundance and investment. The weight given to ecological versus economic resource management registered disproportionate effects due to the interaction between investment and migration rates and resource stochasticity. This finding argued against a "golden mean" rule for evaluating policy trade-offs and sugggested the importance of using a dynamic, socio-ecological perspective in designing policies for rural communities.

description: My work is often times a reflection of human connection. I am fascinated by how and why humans develop deep connections to one another. I was captivated by an image I photographed that depicted a bond between two sisters that existed despite their lack of biological relatedness or racial heritage. Many consider home to be where connections and bonds are created and strengthened. Within these walls, most feel they can be the truest form of themselves. It is within that truth that unconditional bonds without regard to race or biological relatedness may be formed. How do these bonds develop among transracial families?
