description: The Hubbard model is the simplest model of interacting fermions on a lattice and is of similar importance to correlated electron physics as the Ising model is to statistical mechanics or the fruit fly to biomedical science. Despite its simplicity, the model exhibits an incredible wealth of phases, phase transitions, and exotic correlation phenomena. While analytical methods have provided a qualitative description of the model in certain limits, numerical tools have shown impressive progress in achieving quantitative accurate results over the last years. This article gives an introduction to the model, motivates common questions, and illustrates the progress that has been achieved over the last years in revealing various aspects of the correlation physics of the model.

description: Existing approaches to trajectory planning for autonomous racing employ sampling-based methods, generating numerous jerk-optimal trajectories and selecting the most favorable feasible trajectory based on a cost function penalizing deviations from an offline-calculated racing line. While successful on oval tracks, these methods face limitations on complex circuits due to the simplistic geometry of jerk-optimal edges failing to capture the complexity of the racing line. Additionally, they only consider two-dimensional tracks, potentially neglecting or surpassing the actual dynamic potential. In this paper, we present a sampling-based local trajectory planning approach for autonomous racing that can maintain the lap time of the racing line even on complex race tracks and consider the race track's three-dimensional effects. In simulative experiments, we demonstrate that our approach achieves lower lap times and improved utilization of dynamic limits compared to existing approaches. We also investigate the impact of online racing line generation, in which the time-optimal solution is planned from the current vehicle state for a limited spatial horizon, in contrast to a closed racing line calculated offline. We show that combining the sampling-based planner with the online racing line generation can significantly reduce lap times in multi-vehicle scenarios.

description: We hereby develop the theory of Turing instability for reaction-diffusion systems defined on complex networks assuming finite propagation. Extending to networked systems the framework introduced by Cattaneo in the 40's, we remove the unphysical assumption of infinite propagation velocity holding for reaction-diffusion systems, thus allowing to propose a novel view on the fine tuning issue and on existing experiments. We analytically prove that Turing instability, stationary or wave-like, emerges for a much broader set of conditions, e.g., once the activator diffuses faster than the inhibitor or even in the case of inhibitor-inhibitor systems, overcoming thus the classical Turing framework. Analytical results are compared to direct simulations made on the FitzHugh-Nagumo model, extended to the relativistic reaction-diffusion framework with a complex network as substrate for the dynamics.

description: An appealing direction to change the properties of strongly correlated materials is to induce nonequilibrium steady states by the application of a direct current. While access to these novel states is of high scientific interest, Joule heating due to current flow often constitutes a hurdle to identify nonthermal effects. The biggest challenge usually resides in measuring accurately the temperature of a sample subjected to direct current, and to use probes that give direct information of the material. In this work, we exploit the simultaneous measurement of electrical transport and magnetisation to probe non-equilibrium steady states in Ca2RuO4. In order to reveal non-thermal current-induced effects, we employ a simple model of Joule self-heating to remove the effects of heating and discuss the importance of temperature inhomogeneity within the sample. Our approach provides a solid basis for investigating current-induced phenomena in highly resistive materials.

Under a blanket stability assumption, we provide a complete analysis to this problem. In particular, we establish uniqueness of the value function and verification result for optimal stationary Markov controls, in addition to the existence results. We also revisit this problem under a near-monotonicity condition but without any stability hypothesis. Our results also include policy improvement algorithms both in discrete and continuous time frameworks.

description: Higher-order interactions (HOIs) are ubiquitous in real-world complex systems and applications. Investigation of deep learning for HOIs, thus, has become a valuable agenda for the data mining and machine learning communities. As networks of HOIs are expressed mathematically as hypergraphs, hypergraph neural networks (HNNs) have emerged as a powerful tool for representation learning on hypergraphs. Given the emerging trend, we present the first survey dedicated to HNNs, with an in-depth and step-by-step guide. Broadly, the present survey overviews HNN architectures, training strategies, and applications. First, we break existing HNNs down into four design components: (i) input features, (ii) input structures, (iii) message-passing schemes, and (iv) training strategies. Second, we examine how HNNs address and learn HOIs with each of their components. Third, we overview the recent applications of HNNs in recommendation, bioinformatics and medical science, time series analysis, and computer vision. Lastly, we conclude with a discussion on limitations and future directions.

Modeling safe sleep practices in the neonatal intensive care unit: a pilot study
Creators: name: Fitzgerald-Anderson, Raina
Publisher: name: No Publisher Supplied
Year: 2020

description: Purpose of Project: The purpose of this proposed process improvement project was to educate the nursing staff in a level IV NICU about the importance of modeling safe sleep practices for parents and caregivers and to increase the frequency of safe sleep practices used by nursing staff in the NICU.Methodology: The study occurred in 3 phases: pre-interventional, interventional and post interventional. During the Pre and Post- interventional phases nurses were observed to determine if they were utilizing safe sleep recommendations as per AAP recommendations. Data was collected on a safe sleep audit tool. The interventional phase consisted of a self-directed educational model in which the nursing staff learned about infant safe sleep and the importance of modeling safe sleep practices. Pre and Post interventional data were compared to determine if the intervention improved safe sleep practices.Results: Acuity in this level IV NICU was high, therefore few nurses qualified for the study. Due to the small sample size, it could not be determined whether the educational intervention improved the modeling of safe sleep practices. Implications for Practice: Improvements in quality and safety of infant care in the NICU can occur by standardizing nursing practice and allow families to receive a consistent message while observing appropriate modeling of safe sleep practices.
Subcortical origins of orientation and direction sensitivity in the cat's visual pathway
Creators: name: Thompson, Kirk Gerald
Publisher: name: University of Utah
Year: 2012

description: The aim of the first investigation of this dissertation was to study the orientation and direction sensitivity of cat LGNd cells using drifting gratings, bars and spots. Seventy-five percent of the LGNd cells studied were orientation sensitive and about one third were direction sensitive. In general, orientation tuning was strongest at high spatial frequencies, whereas direction tuning was strongest at low spatial frequencies. Thus, subcortical orientation and direction sensitivity may be important for the generation of the high degree of selectivity found in visual cortex.  In the second study, cortical contributions to the orientation and direction sensitivities of LGNd relay cells was investigated by recording from LGNd cells in cats in which the visual cortex was inactivated. For comparison, the orientation and direction tuning of striate cortical cells was also studied. There were no significant differences in the orientation and direction tuning of relay cells in the LGNd of normal and decorticate cats. The orientation and direction sensitivities of cortical cells were also found to be stimulus dependent in a fashion qualitatively similar to that of LGNd cells.  Many of the differences between LGNd cells and cortical cells are explained by their differences in spatial frequency tuning. These findings are consistent with the hypothesis that the orientation and direction biases present in the LGNd inputs to the visual cortex contribute to the strong orientation and direction selectivities found in cortical cells.  Finally, direction sensitivity in retinal ganglion cells was studied. The visual responses of retinal ganglion cells were recorded intraocularly using the same visual stimuli employed to study LGNd and cortical cells. Most cat retinal ganglion cells exhibit orientation biases when tested with gratings of relatively high spatial frequency. About 20% of the X- and Y-type retinal ganglion cells exhibited a clear direction bias that was usually clearest when the test grating was of relatively low spatial frequency. The direction sensitive responses of cat retinal ganglion cells were similar to those of X- and Y-cells in the cat LGNd. This suggests that the direction sensitivity of LGNd cells is a reflection of their retinal inputs.

description: We study nonzero-sum stochastic games for continuous time Markov decision processes on a denumerable state space with risk-sensitive ergodic cost criterion. Transition rates and cost rates are allowed to be unbounded. Under a Lyapunov type stability assumption, we show that the corresponding system of coupled HJB equations admits a solution which leads to the existence of a Nash equilibrium in stationary strategies. We establish this using an approach involving principal eigenvalues associated with the HJB equations. Furthermore, exploiting appropriate stochastic representation of principal eigenfunctions, we completely characterize Nash equilibria in the space of stationary Markov strategies.

description: In a modern distributed storage system, storage nodes are organized in racks, and the cross-rack communication dominates the system bandwidth. In We study the rack-aware storage system where all storage nodes are organized in racks and within each rack the nodes can communicate freely without taxing the system bandwidth. Rack-aware regenerating codes (RRCs) were proposed for minimizing the repair bandwidth for single erasures. In the initial setting of RRCs, the repair of a single node requires the participation of all the remaining nodes in the rack containing the failed node as well as a large number of helper racks containing no failures. Consequently, the repair may be infeasible in front of multiple node failures. In this work, a relaxed repair model that can tolerate multiple node failures by simultaneously reducing the intra-rack connections and cross-rack connections is proposed. A tradeoff between the storage and repair bandwidth under the relaxed repair model is derived, and parameters of the two extreme points on the tradeoff curve are characterized for the minimum storage and minimum bandwidth respectively. Moreover, two codes corresponding to the extreme points are explicitly constructed over the fields of size comparable to the code length and with the lowest sub-packetization. Finally, for the convenience of practical use, systematic encoding processes for the two codes are also established.

description: The Internet of Things (IoT) is a communication scheme which allows various objects to exchange several types of information, enabling functions such as home automation, production management, healthcare, etc. In addition, energy-harvesting (EH) technology is considered for IoT environment in order to reduce the need for management and enhance maintainability. Moreover, since environments considering outdoor elements such as pedestrians, vehicles and drones have been on the rise recently, it is important to consider mobility when designing an IoT network management scheme. However, calculating the optimal relaying topology is considered as an NP-hard problem, and finishing computation for mobility environment before the channel status changes is important to prevent delayed calculation results. In this article, our objective is to calculate a sub-optimal relaying topology for stationary and mobile system within reasonable computation time. To achieve our objective, we validate an iterative balancing time slot allocation algorithm introduced in the previous study, and propose a guided-mutation genetic algorithm (GMGA) that modulates the mutation rate based on the channel status for rational exploration. Additionally, we propose a mobility-aware iterative relaying topology algorithm, which calculates relaying topology in a mobility environment using an inheritance of the sub-optimal relaying topology calculations. Simulation results verify that our proposed scheme effectively solves formulated IoT network problems compared to other conventional schemes, and also effectively handles IoT environments including mobility in terms of minimum rate budget and computation time.

description: In a series of recent articles, Liu, Yang, Pan, et al. claim to have determined the exact dressed electron-boson vertex for a number of very general interacting many-body problems by inverting certain Ward-Takahashi identities. Here, we point out that their Ward-Takahashi identities are missing terms which make the inversion of the identities impossible. One therefore cannot formulate exact self-contained integral equations for the dressed electron propagator. In addition, the proposed vertex expressions do not reproduce well-established results for the leading perturbative corrections.

description: Scanning Kelvin probe microscopy (SKPM) is a powerful technique for investigating the electrostatic properties of material surfaces, enabling the imaging of variations in work function, topology, surface charge density, or combinations thereof. Regardless of the underlying signal source, SKPM results in a voltage image which is spatially distorted due to the finite size of the probe, long-range electrostatic interactions, mechanical and electrical noise, and the finite response time of the electronics. In order to recover the underlying signal, it is necessary to deconvolve the measurement with an appropriate point spread function (PSF) that accounts the aforementioned distortions, but determining this PSF is difficult. Here we describe how such PSFs can be determined experimentally, and show how they can be used to recover the underlying information of interest. We first consider the physical principles that enable SKPM, and discuss how these affect the system PSF. We then show how one can experimentally measure PSFs by looking at well defined features, and that these compare well to simulated PSFs, provided scans are performed extremely slowly and carefully. Next, we work at realistic scan speeds, and show that the idealised PSFs fail to capture temporal distortions in the scan direction. While simulating PSFs for these situations would be quite challenging, we show that measuring PSFs with similar scan conditions works well. Our approach clarifies the basic principles of and inherent challenges to SKPM measurements, and gives practical methods to improve results

description: The primary focus of this work is an assessment of heat transfer to and from a reversible thermosiphon imbedded in porous media. The interest in this study is the improvement of underground thermal energy storage (UTES) system performance with an innovative ground coupling using an array of reversible (pump-assisted) thermosiphons for air conditioning or space  cooling applications. The dominant mechanisms, including the potential for heat transfer enhancement due to natural convection, of seasonal storage of "cold" in water-saturated porous media is evaluated experimentally and numerically. Winter and summer modes of operation are studied.  A set of 6 experiments are reported that describe the heat transfer in both fine and coarse sand in a 0.32 cubic meter circular tank, saturated with water, under freezing (due to heat extraction) and thawing (due to heat injection) conditions, driven by the heat transfer to or from the vertical thermosiphon in the center of the tank. It was found that moderate to strong natural convection was induced at Rayleigh numbers of 30 or higher. Also, near water freezing temperatures (0°C-10°C), due to higher viscosity of water at lower temperatures, almost no natural convection was observed.  A commercial heat transfer code, ANSYS FLUENT, was used to simulate both the heating and cooling conditions, including liquid/solid phase change. The numerical simulations of heat extraction from different permeability and temperature water-saturated porous media  showed that enhancement to heat transfer by convection becomes significant only under conditions where the Rayleigh number is in the range of 100 or above. Those conditions would be found only for heat storage applications with higher temperatures of water (thus, its lower viscosity) and large temperature gradients at the beginning of heat injection (or removal) into (from) soil. For "cold" storage applications, the contribution of natural convection to heat transfer in water-saturated soils would be negligible. Thus, the dominant heat transfer mechanism for air conditioning applications of UTES can be assumed to be conduction.  An evaluation of the potential for heat transfer enhancement in air-saturated media is also reported. It was found that natural convection in soils with high permeability and air saturations near 1 becomes more important as temperatures drop significantly below freezing.

description: We consider almost sure convergence of the SDE $dX_t=α_t d t + β_t d W_t$ under the existence of a $C^2$-Lyapunov function $F:\mathbb R^d \to \mathbb R$. More explicitly, we show that on the event that the process stays local we have almost sure convergence in the Lyapunov function $(F(X_t))$ as well as $\nabla F(X_t)\to 0$, if $|β_t|=\mathcal O( t^{-β})$ for a $β>1/2$. If, additionally, one assumes that $F$ is a Lojasiewicz function, we get almost sure convergence of the process itself, given that $|β_t|=\mathcal O(t^{-β})$ for a $β>1$. The assumptions are shown to be optimal in the sense that there is a divergent counterexample where $|β_t|$ is of order $t^{-1}$.

description: The Ablowitz-Ladik chain is an integrable discretized version of the nonlinear Schrödinger equation. We report on a novel underlying Hamiltonian particle system with properties similar to the ones known for the classical Toda chain and Calogero fluid with $1/\sinh^2$ pair interaction. Boundary conditions are imposed such that, both in the distant past and future, particles have a constant velocity. We establish the many-particle scattering for the Ablowitz-Ladik chain and obtain properties known for generic integrable many-body systems. For a specific choice of the chain, real initial data remain real in the course of time. Then, asymptotically, particles move in pairs with a velocity-dependent size and scattering shifts are governed by the fusion rule.

Child rearing

description: A need to do an exploratory study of the Navajo traditional child rearing practices grew out of a  discussion between key personnel and five Navajo graduate students at the University of Utah Graduate School of Social Work. The result led to a  study of traditional Navajo child rearing practices. The study population included 56 (100%) elderly Navajo men and women over the age 60, who had substantial know-ledge of child rearing based upon their own experiences. The information gathered were done in the Navajo language. A minimum of 25 hours of interviewing time, with an average of approximately two hours were spent with each informant who were selected across the Navajo Reservation. This study explored the traditional Navajo child rearing patterns among the Navajos from prenatal period to age three. The following factors were identified as the basic elements in what may be presumed to be typical child rearing patterns. The four phases identified were: (1) Pre-birth, (2) Pre-cradle Board, (3) Cradle Board, and (4) Post-cradle Board. The study revealed that there were evidences of typical Navajo child rearing practices of growth and development which were organized in a  chronological life experience framework in the Navajo cultural context of personality development. It was also found that values, beliefs, cultural practices and the extended family system played an important role in each of the above mentioned phases of the traditional Navajo child rearing patterns.

description: We analyze the $L^1$-mixing of a generalization of the Averaging process introduced by Aldous. The process takes place on a growing sequence of graphs which we assume to be finite-dimensional, in the sense that the random walk on those geometries satisfies a family of Nash inequalities. As a byproduct of our analysis, we provide a complete picture of the total variation mixing of a discrete dual of the Averaging process, which we call Binomial Splitting process. A single particle of this process is essentially the random walk on the underlying graph. When several particles evolve together, they interact by synchronizing their jumps when placed on neighboring sites. We show that, given $k$ the number of particles and $n$ the (growing) size of the underlying graph, the system exhibits cutoff in total variation if $k\to\infty$ and $k=O(n^2)$. Finally, we exploit the duality between the two processes to show that the Binomial Splitting satisfies a version of Aldous' spectral gap identity, namely, the relaxation time of the process is independent of the number of particles.

Health, medicine, and power in the Salt Lake Valley, Utah, 1869-1945

description: This dissertation examines the social history of medicine in the Salt Lake Valley, Utah, from the late nineteenth to the mid-twentieth century. It contends that race and class played disproportionate roles in the creation and evolution of Progressive Era health reforms. White middle-class residents embraced new scientific theories about physical health to bring about much needed programs in public sanitation and vaccination, hospital care, welfare services for the poor, and workplace safety legislation-all of which became necessary as Utah experienced increased immigration, industrialization, and urbanization at the turn of the century. Although these programs sometimes became embroiled in religious disputes between Mormons (members of the Church of Jesus Christ of Latter-day Saints) and non-Mormon "gentiles," after Utah statehood in 1896 and efforts by Mormons to Americanize, religious tension diminished to allow powerful whites to implement and unequally benefit from these programs. As a result, affluent Mormons and gentiles enjoyed increased opportunities to improve the cleanliness and health of their bodies, living and working spaces, and to claim membership in the upstanding white American middle-class. By virtue of their racial, ethnic, and socio-economic status, however, poor non-white immigrants from southern and eastern Europe, Asia, Latin America, and beyond suffered decreased opportunities to do the same. They experienced higher rates iv of contagious and infectious disease, accidents and injuries, poor living and working conditions, and accusations of their inability or unwillingness to assimilate into the healthy national mainstream. Yet they resisted inequality through a variety of means, including building hospitals, establishing mutual aid programs, practicing Western medicine, and embracing folk cures. Progressive middle-class whites observed, overlooked, or diminished the significance of these activities to grade and differentiate the laboring poor. White British miners seemed to be more committed to health and progress than did Greek, Italian, Chinese, and Mexican migrants, while Japanese residents appeared to be the cleanest, most American, and acceptable non-whites, until the Japanese bombing of Pearl Harbor. After World War II, health inequality continued to drive many poor non-whites from Utah and allow middle-class whites to retain control over medicine, health, and power in the Salt Lake Valley.

description: Uncertainty principle reveals the intrinsic differences between the classical and quantum worlds, which plays a significant role in quantum information theory. By using $ρ$-absolute variance, we introduce the uncertainty of quantum channels and explore its properties. By using Cauchy-Schwarz inequality and the parallelogram law, we establish the product and summation forms of the uncertainty relations for arbitrary two quantum channels, respectively. The summation form of the uncertainty inequalities based on the $ρ$-absolute variance for arbitrary $N$ quantum channels are also investigated and the optimal lower bounds are presented. We illustrate our results by several typical examples.

description: An important aspect of the propagation delay in blockchain networks is the block verification time, which is also responsible for the so-called verifier's dilemma. Models for the block verification time can help to understand and improve the verification process. Moreover, modeling the verification time is necessary for blockchain network simulations. In this paper, we present JOIST, a new model for the block verification time of Zcash. We identify computationally complex operations in the verification process of Zcash, and derive our model based on characteristic transaction features. We evaluate JOIST and show that the model is consistently more accurate than existing models, which consider the block size only.
