description: We show that central extensions of the mapping class group $M_g$ of the closed orientable surface of genus $g$ by $\Z$ are residually finite. Further we give rough estimates of the largest $N=N_g$ such that homomorphisms from $M_g$ to SU(N) have finite image. In particular, homomorphisms of $M_g$ into $SL([\sqrt{g+1}],\C)$ have finite image. Both results come from properties of quantum representations of mapping class groups.

An analytical methodology for short run urban transportation policy questions
Creators: name: Culham, Thomas Elwood
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of this paper was to develop an analytical framework to answer short range policy questions. This type of framework is needed because until recently most models dealt with long range capital investment decisions while many urban transportation problems may be solved through low capital cost policy decisions. The literature indicated that equilibrium techniques were essential in providing solutions to short run policy questions. The features of equilibrium theory in general were examined. The theory was then discussed in terms of an application. It was found that the equilibrium state may be obtained through a direct or indirect modelling approach. The direct approach utilizes a single modelling step while the indirect approach utilizes several sub-models. The state of the art is such that it appeared that the sequential indirect approach was the best method to use. A computer modelling framework was developed which included modifications and additions to a system produced at the University of British Columbia. The purpose of the U.B.C. system was to provide detailed analysis of traffic movements over localized traffic networks. The modelling contributions of this paper were the detailed description of the transit user through his trip from origin to destination and the assembly of an automobile assignment model, parking allocation model, transit assignment model and an auto-transit demand model into an equilibrium framework. The new system was tested on a small network. It produced "reasonable results". Reasonable in this case implied: (1) that any changes in service levels or parking costs will result in shifts of demand in the appropriate direction and; (2) that changes in demand will be in proportion to the change in level of service and vice versa. Two parking policies were analysed. The first policy approximated the case where a municipality decides to increase the rates in its own parking lots. Prices were increased on one out of four lots in the test network. The second policy approximated the case where the government is able to levy a tax on all parking lots. Prices were increased on all lots in the test network. The outcome produced by the model confirmed the experience with parking price increases; that is, for parking policies to be effective in reducing congestion, it is necessary to control all parking spaces in the C.B.D.. A number of recommendations arose from the analysis of the results from the test network. It was recommended that further tests be carried out on a more realistic network, and that a set of refinements and sensitivity tests be made on some of the sub-models in the system. In general the model appeared to be sensitive to changes in attributes of transportation alternatives. The development of this system was a step to fill the gap in the armoury of analytical tools. Further work and research may show it to' be useful in practical applications.
title: Holistic Assessment of Narrative Discourse: A Progress Monitoring Tool
Creators: name: Beck, Teigan
Publisher: name: Utah State University
Year: 2019

description: Purpose: The purpose of this study was to design and evaluate the validity, developmental sensitivity, and scoring reliability of a rubric for measuring the holistic quality of stories for preschool and school age children.
Method: 224 children, ages 4-7, told stories in a single structured context which were then scored by a group of trained raters using the Holistic Assessment of Narrative Discourse (HAND) to evaluate aspects of its psychometric adequacy, specifically validity, developmental sensitivity, and inter-rater reliability.
Results: The results showed that the scores on the HAND were a valid measure of narrative quality that were sensitive to developmental changes over age and could be scored reliably.
Conclusion: This tool may be a useful adjunct to traditional measures for characterizing children’s narratives.

description: We explore two-dimensional sigma models with (0,2) supersymmetry through their chiral algebras. Perturbatively, the chiral algebras of (0,2) models have a rich infinite-dimensional structure described by the cohomology of a sheaf of chiral differential operators. Nonperturbatively, instantons can deform this structure drastically. We show that under some conditions they even annihilate the whole algebra, thereby triggering the spontaneous breaking of supersymmetry. For a certain class of Kähler manifolds, this suggests that there are no harmonic spinors on their loop spaces and gives a physical proof of the Höhn-Stolz conjecture.

Partial, zombie, and full tidal disruption of stars by supermassive black holes

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

description: We present long-duration numerical simulations of the tidal disruption of stars modelled with accurate stellar structures and spanning a range of pericentre distances, corresponding to cases where the stars are partially and completely disrupted. We substantiate the prediction that the late-time power-law index of the fallback rate $n_{\infty} \simeq -5/3$ for full disruptions, while for partial disruptions---in which the central part of the star survives the tidal encounter intact---we show that $n_{\infty} \simeq -9/4$. For the subset of simulations where the pericenter distance is close to that which delineates full from partial disruption, we find that a stellar core can reform after the star has been completely destroyed; for these events the energy of the zombie core is slightly positive, which results in late-time evolution from $n \simeq -9/4$ to $n \simeq -5/3$. We find that self-gravity can generate an $n(t)$ that deviates from $n_{\infty}$ by a small but significant amount for several years post-disruption. In one specific case with the stellar pericenter near the critical value, we find self-gravity also drives the re-collapse of the central regions of the debris stream into a collection of several cores while the rest of the stream remains relatively smooth. We also show that it is possible for the surviving stellar core in a partial disruption to acquire a circumstellar disc that is shed from the rapidly rotating core. Finally, we provide a novel analytical fitting function for the fallback rates that may also be useful in a range of contexts beyond TDEs.

The Infancy of Cosmic Reionization

Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We consider the early stages of cosmic hydrogen or helium reionization, when ionizing sources were still rare. We show that Poisson fluctuations in the galaxy distribution substantially affected the early bubble size distribution, although galaxy clustering was also an essential factor even at the earliest times. We find that even at high redshifts, a significant fraction of the ionized volume resided in bubbles containing multiple sources, regardless of the ionizing efficiency of sources or of the reionization redshift. In particular, for helium reionization by quasars, one-source bubbles last dominated (i.e., contained 90% of the ionized volume) at some redshift above z=7.3, and hydrogen reionization by stars achieved this milestone at z>23. For the early generations of atomic-cooling halos or molecular-hydrogen-cooling halos, one-source ionized regions dominated the ionized volume only at z>31 and z>48, respectively. To arrive at these results we develop a statistical model for the effect of density correlations and discrete sources on reionization and solve it with a Monte Carlo method.

description: A significant fraction of binary neutron star mergers occur in star-forming galaxies where the UV-optical and soft X-ray afterglow emission from the relativistic jet may be absorbed by dust and re-emitted at longer wavelengths. We show that, for mergers occurring in gas-rich environment (n_H > 0.5 cm^{-3} at a few to tens of pc) and when the viewing angle is less than about 30 degrees, the emission from heated dust should be detectable by James Webb Space Telescope (JWST), with a detection rate of the order once per year. The spatial separation between the dust emission and the merger site is a few to 10 milli-arcsecs (for a source distance of 150 Mpc), which may be astrometrically resolved by JWST for sufficiently high signal-noise-ratio detections. Measuring the superluminal apparent speed of the flux centroid directly gives the orbital inclination of the merger, which can be combined with gravitational wave data to measure the Hubble constant. For a line of sight within the jet opening angle, the dust echoes are much brighter and may contaminate the search for kilonova candidates from short gamma-ray bursts, such as the case of GRB 130603B.

description: Distinguishing the dynamics of an Anderson insulator from a Many-Body Localized (MBL) phase is an experimentally challenging task. In this work, we propose a method based on machine learning techniques to analyze experimental snapshot data to separate the two phases. We show how to train $3D$ convolutional neural networks (CNNs) using space-time Fock-state snapshots, allowing us to obtain dynamic information about the system. We benchmark our method on a paradigmatic model showing MBL ($t-V$ model with quenched disorder), where we obtain a classification accuracy of $\approx 80 \%$ between an Anderson insulator and an MBL phase. We underline the importance of providing temporal information to the CNNs and we show that CNNs learn the crucial difference between an Anderson localized and an MBL phase, namely the difference in the propagation of quantum correlations. Particularly, we show that the misclassified MBL samples are characterized by an unusually slow propagation of quantum correlations, and thus the CNNs label them wrongly as Anderson localized. Finally, we apply our method to the case with quasi-periodic potential, known as the Aubry-André model (AA model). We find that the CNNs have more difficulties in separating the two phases. We show that these difficulties are due to the fact that the MBL phase of the AA model is characterized by a slower information propagation for numerically accessible system sizes.

description: Socially interactive agents (SIAs) are no longer mere visions for future user interfaces, as 20 years of research and technology development has enabled the use of virtual and physical agents in day-to-day interfaces and environments. This chapter of the ACM "The Handbook on Socially Interactive Agents" reviews research on and technologies involving socially interactive agents, including virtually embodied agents and physically embodied robots, focusing particularly on the appearance of socially interactive agents. It covers the history of the development of these technologies; outlines the design space for the appearance of agents, including what appearance comprises, modalities in which agents are presented, and how agents are constructed; and the features that agents use to support social interaction, including facial and bodily features, those that express demographic characteristics, and issues surrounding realism, appeal, and the uncanny valley. The chapter concludes with a brief discussion of open questions surrounding the appearance of socially interactive agents.

The key point is a reformulation of the concept of logarithmic structure in the language of symmetric monoidal categories, which might be of independent interest. Our main result states that parabolic sheaves can be interpreted as quasi-coherent sheaves on certain stacks of roots.

description: Cerium diantimonide (CeSb$_2$) is one of a family of rare earth based magnetic materials that exhibit metamagnetism, enabling control of the magnetic ground state through an applied magnetic field. At low temperatures, CeSb$_2$ hosts a rich phase diagram with multiple magnetically ordered phases for many of which the order parameter is only poorly understood. In this paper, we report a study of its metamagnetic properties by Scanning Tunneling Microscopy (STM) and magnetization measurements. We use STM measurements to characterize the sample magnetostriction with sub-picometer resolution from magnetic field and temperature sweeps. This allows us to directly assess the bulk phase diagram as a function of field and temperature and relate spectroscopic features from tunneling spectroscopy to bulk phases. Our magnetostriction and magnetisation measurements indicate that the low temperature ground state at zero field is ferrimagnetic. Quasiparticle interference mapping shows evidence for a reconstruction of the electronic structure close to the Fermi energy upon entering the magnetically ordered phase.

description: Galaxy Zoo is the first study of nearby galaxies that contains reliable information about the spiral sense of rotation of galaxy arms for a sizeable number of galaxies. We measure the correlation function of spin chirality (the sense in which galaxies appear to be spinning) of face-on spiral galaxies in angular, real and projected spaces. Our results indicate a hint of positive correlation at separations less than ~0.5 Mpc at a statistical significance of 2-3 sigma. This is the first experimental evidence for chiral correlation of spins. Within tidal torque theory it indicates that the inertia tensors of nearby galaxies are correlated. This is complementary to the studies of nearby spin axis correlations that probe the correlations of the tidal field. Theoretical interpretation is made difficult by the small distances at which the correlations are detected, implying that substructure might play a significant role, and our necessary selection of face-on spiral galaxies, rather than a general volume-limited sample.

The removal of organics from municipal wastewaters by lime magnesium coagulation
Creators: name: Leung, Yuk-Ching
Publisher: name: University of British Columbia
Year: 2010

description: In view of a potentially hazardous problem existing in municipal wastewater due to heavy metals and trace organics, this research attempted to find the removal efficiency of trace organics that could be achieved by chemical treatment (lime-magnesium coagulation) instead of by conventional biological treatment. Pesticides, polychlorinated biphenyls (PCB's) and phenols were chosen because of their high toxicity, existence in significant quantities, and ubiquitous nature. Extraction, concentration, derivatization and gas liquid chromatography (GLC) were employed to detect these compounds. Jar tests at pH 10.0, 10.7 and 11.4 with magnesium (Mg²⁺) dosages of 0, 8, 17, 33 and 50 mg/l were carried out to find the optimum removal condition. Very high removal of each from an initial concentration of 250 μg/l could be obtained, although not under the same experimental conditions. The highest removal efficiencies of Dieldrin, Aroclor 1254, Dichlorvos and Pentachlorophenol were 88.1%, over 95%, over 80% and 7 3.5% respectively. The two optimum dosages found were 8 mg/l Mg²⁺ at pH 10.7 and 33 mg/l Mg²⁺ at pH 11.4. The former combination of conditions is worthy of consideration when magnesium and lime recycle are not practised, especially with regard to sludge handling, chemicals used and final pH adjustment. The latter set of consideration when lime and magnesium recycle are included. Whether lime-magnesium coagulation can be a cost-effective treatment process for municipal wastewater, and how it can be instituted within existing treatment plants, still requires further investigation.
title: Alternative Futures for Dalton Wells

Publisher: name: Utah State University
Year: 2019

description: Visitation to the Moab region has increased significantly in recent years, causing campgrounds near town to be consistently full. The Dalton Wells area, a recreation area off Highway 191 just north of Moab, has become an especially popular place for dispersed camping, as it is free and in close proximity to town. Dalton Wells does not have the infrastructure or management necessary to support the current number of visitors, straining the site’s fragile desert ecosystem. The site also hosts a dinosaur quarry and the foundations of a historic CCC camp. These resources are unmaintained and at risk of pillaging and decay. State Sovereign Lands has ownership of Dalton Wells, and is in need of a plan that would provide public access for campers and other recreationalists who use the area’s trail systems, while protecting the cultural and natural resources of the site. The objective of this thesis is to address State Sovereign Land's need, and identify and resolve the issues caused by dispersed camping at Dalton Wells. This project utilizes the Bioregional Planning Process, a system of planning which considers how bio-physical, socio-cultural, and economic land use patterns influence future plans and development. For Dalton Wells, a larger, landscape-level analysis will inform the design, development, and programming of a site-scale master plan. The planning process includes a pre-analysis with site visits and stakeholder meetings, documenting the structure and function of the landscape, landscape analysis and mapping, modeling land-use alternatives, and the development of a master plan. The resulting master plan will resolve the issues caused by dispersed camping at Dalton Wells, by providing campgrounds, day use areas, and other recreational infrastructure, and improving the system of roads, trailheads, and signage at the site. The master plan will also celebrate the existing CCC Camp and Dinosaur Quarry, by finding appropriate solutions for interpretive programming. Finally, the plan will provide recommendations for management and protection of the site’s scenic qualities.

description: Warm ionized and cold neutral outflows with velocities exceeding $100\,{\rm km\,s}^{-1}$ are commonly observed in galaxies and clusters. Theoretical studies however indicate that ram pressure from a hot wind, driven either by the central active galactic nucleus (AGN) or a starburst, cannot accelerate existing cold gas to such high speeds without destroying it. In this work we explore a different scenario, where cold gas forms in a fast, radiatively cooling outflow with temperature $T\lesssim 10^7\,{\rm K}$. Using 3D hydrodynamic simulations, we demonstrate that cold gas continuously fragments out of the cooling outflow, forming elongated filamentary structures extending tens of kiloparsecs. For a range of physically relevant temperature and velocity configurations, a ring of cold gas perpendicular to the direction of motion forms in the outflow. This naturally explains the formation of transverse cold gas filaments such as the blue loop and the horseshoe filament in the Perseus cluster. Based on our results, we estimate that the AGN outburst responsible for the formation of these two features drove bipolar outflows with velocity $>2,000\,{\rm km\,s}^{-1}$ and total kinetic energy $>8\times10^{57}\,{\rm erg}$ about $\sim10$ Myr ago. We also examine the continuous cooling in the mixing layer between hot and cold gas, and find that radiative cooling only accounts for $\sim10\%$ of the total mass cooling rate, indicating that observations of soft X-ray and FUV emission may significantly underestimate the growth of cold gas in the cooling flow of galaxy clusters.

title: Interaction of Soil and Seepage Barrier Cracks under Seepage Flow
Creators: name: Whitmer, Justin
Publisher: name: Utah State University

description: Seepage barriers are commonly installed in earthen dams and levees all over the world and consist of slurry walls, concrete walls, jet grouted walls, secant pile walls, sheet pile walls, and deep soil mixed walls. The purpose of the barrier is to reduce the amount of flow and seepage through the embankment and the foundation of the dam or levee. When seepage barriers were first being used it was under the impression that barriers would be a permanent mitigation of seepage problems. However, in prior research (Rice, 2007) it is mentioned that there are several cases where the seepage barriers did not perform as expected, concluding that there may be failure mechanisms that are unique to each seepage barrier. When a crack is introduced to the seepage barrier, in some cases internal erosion may be taking place causing the crack to widen. As the crack gets wider the flow through that crack may increase until a point when the soil controls the amount of flow into the crack or soil starts to fill the crack.
This study compares theoretical values vs. measured values of flow and head readings using a laboratory test cell for the measured values and a finite element analysis computer program for theoretical. Also looked at is the interaction of the sand and the crack for variables of flow and erosion. Taken into account are variables for crack type (smooth and fractured), crack aperture, and the hydraulic conductivity of the sand placed around the seepage barrier. This is done by modeling the crack through a seepage barrier test cell for different apertures and different head values.

description: The science of water resource planning and management implies the utilization of available water supplies in order to meet specific goals and objectives (Hill and Riley, 1972). Essential to effective planning and management is the consideration and analysis of all possible alternatives. Past research at Utah State University has demonstrated that the hybrid computer simulation of hydrologic processes is a reliable planning technique which provides the capability to examine many possible alternatives in a short period of time (Hill et al., 1970; Riley, 1970; and Riley et al., 1967). This technique, because of its interactive characteristics, is valuable also in teaching some basic concepts of hydrology and water resource management.

description: Electroweak baryogenesis (EWBG) is sourced by nonstandard $CP$-violating interactions of the Higgs boson with fermions, usually taken to be the top quark, enhanced by its large Yukawa coupling. Numerous papers have studied EWBG sourced by lighter fermions, including the tau lepton and off-diagonal quark mass terms. We critically reassess the viability of EWBG in these scenarios, comparing the predictions based on the semiclassical (WKB) formalism for the source term to those from the VEV insertion approximation (VIA), using updated values for the collision terms, and clarifying discrepancies in the definition of the weak sphaleron rate. The VIA systematically predicts a baryon asymmetry that is orders of magnitude larger than the WKB formalism. We trace this to the differing shapes of the $CP$-violating source terms in the two formalisms, showing that the additional spatial derivative in the WKB source term causes large cancellations when it is integrated over the bubble wall profile. An important exception is a source term from $c$-$t$ quark mixing, where the WKB prediction also allows for a realistically large baryon asymmetry. In contrast, the analogous $b$-$s$ mixing source is found to be orders of magnitude too small.

description: Microscopic bioimaging is a useful approach to study cell-biomaterial interactions which are vital to the biomedical application of biomaterials. Through microscopic imaging, numerous cellular responses, such as proliferation, uptake, and death, can be recorded, characterized and analyzed.
In this thesis, I first provided basic introductions to the imaging techniques and analysis tools, especially those that are highly relevant to the studies of biomaterials and cell interactions. I also detailed the adaptation of these techniques and tools in the application of two specific research projects in biomaterials, with special focuses on the imaging and analysis.
The first project assessed the subtle cytotoxicity of 3D-printed polymers due to the leachable impurities, and the remedy effects of three post-printing treatment methods that reduce the leachables. I demonstrated how a long-term time-lapse imaging method was applied and how the imaging data were analyzed for the assessment of the cytotoxicity under various treatment conditions. The results suggested that the cytotoxicity of 3D-printed materials occurred in a leachable manner. Effective detoxification methods were identified and validated using this imaging method.
The second project studied the selective cytotoxicity and traceable internalization of ZnO nanoparticles in brain tumor cells. As an important component of this study, I demonstrated how a confocal microscopic method was adapted to trace nanoparticles in cell cultures using a microfluidic imaging chamber; which fluorescently imaged the nanoparticles in high resolution. Through the 3D rendering of z-stacks, the localization of the internalized nanoparticles was revealed, as the majority entered in the cytoplasm.
title: Comparison of Induced and Parasitic Drag  on Wings with Minimum Induced Drag
Creators: name: Abdel-Motaleb, Sarah A.
Publisher: name: Utah State University
Year: 2019

description: Minimizing the induced drag for steady level flight is a variational problem that requires solving for the optimum lift distribution given a set of design constraints. From lifting-line theory, minimizing the induced drag is, in part, achieved by varying the Fourier coefficients used to describe the section lift. The elliptic lift distribution minimizes the induced drag for a wing with fixed weight and wingspan by setting all but the first coefficient to zero. If wingspan is allowed to vary, a negative third Fourier coefficient is utilized to reach an optimum lift distribution that further reduces the induced drag for stress-limited designs. However, to produce an optimal section-lift distribution for minimum induced drag, the wing is required to vary twist along the span, which contributes to the parasitic drag component and may compromise the benefits gained from minimizing the induced drag. Here, the effect of these lift distributions on the parasitic drag is investigated. It is shown that twisting the wing to produce optimal lift distribution that minimizes induced drag can increase the parasitic drag values enough to nearly cancel or surpass the benefits gained by the reduction of the induced drag depending on the aircraft and flight conditions. One aircraft example is studied. Other aircraft might have different results.

description: Neutron star merger accretion discs can launch neutron-rich winds of $>10^{-2}\,\mathrm{M}_\odot$. This ejecta is a prime site for r-process nucleosynthesis, which will produce a range of radioactive heavy nuclei. The decay of these nuclei releases enough energy to accelerate portions of the wind by ~0.1c. Here, we investigate the effect of r-process heating on the dynamical evolution of disc winds. We extract the wind from a 3D general relativistic magnetohydrodynamic simulation of a disc from a post-merger system. This is used to create inner boundary conditions for 2D hydrodynamic simulations that continue the original 3D simulation. We perform two such simulations: one that includes the r-process heating, and another one that does not. We follow the hydrodynamic simulations until the winds reach homology (60 seconds). Using time-dependent multi-frequency multi-dimensional Monte Carlo radiation transport simulations, we then calculate the kilonova light curves from the winds with and without dynamical r-process heating. We find that the r-process heating can substantially alter the velocity distribution of the wind, shifting the mass-weighted median velocity from 0.06c to 0.12c. The inclusion of the dynamical r-process heating makes the light curve brighter and bluer at ~1 d post-merger. However, the high-velocity tail of the ejecta distribution and the early light curves are largely unaffected.

description: We report the results of a local stability analysis for a magnetized, gravitationally stratified plasma containing cosmic rays. We account for cosmic-ray diffusion and thermal conduction parallel to the magnetic field and allow beta to take any value, where p is the plasma pressure and B is the magnetic field strength. We take the gravitational acceleration to be in the -z-direction and the equilibrium magnetic field to be in the y-direction, and we derive the dispersion relation for small-amplitude instabilities and waves in the large-|k_x| limit. We use the Routh-Hurwitz criterion to show analytically that the necessary and sufficient criterion for stability in this limit is n k_B dT/dz + dp_cr/dz + (1/8pi)dB^2/dz > 0, where T is the temperature, n is the number density of thermal particles, and p_cr is the cosmic-ray pressure. We present approximate analytical solutions for the normal modes in the low- and high-diffusivity limits, show that they are consistent with the derived stability criterion, and compare them to numerical results obtained from the full, unapproximated, dispersion relation. Our results extend earlier analyses of buoyancy instabilities in galaxy-cluster plasmas to the beta <= 1 regime. Our results also extend earlier analyses of the Parker instability to account for anisotropic thermal conduction, and show that the interstellar medium is more unstable to the Parker instability than was predicted by previous studies in which the thermal plasma was treated as adiabatic.

description: The Fukui-Todo algorithm is an important element of the array of simulational approaches to tackling critical phenomena in statistical physics. The partition-function-zero approach is of fundamental importance to understanding such phenomena and a precise tool to measure their properties. However, because the Fukui-Todo algorithm bypasses sample-by-sample energy computation, zeros cannot easily be harnessed through the energy distribution. Here this obstacle is overcome by a novel reweighting technique and zero-detection protocol. The efficacy of the approach is demonstrated in simple iconic models which feature transitions of both first and second order.
