description: We report the Chandra discovery of an X-ray cluster at redshift z = 1.063 associated with the Compact Steep Spectrum radio loud quasar 3C 186 (Q0740+380). Diffuse X-ray emission is detected out to ~120 kpc from the quasar and contains 741+/-40 net counts. The X-ray spectrum of the extended emission shows strong Fe-line emission (EW=412eV) at the quasar redshift and confirms the thermal nature of this diffuse component. We measure a cluster temperature of 5.2(+1.2/-0.9) keV and an X-ray luminosity L(0.5-2 keV) ~ 6e44 erg/sec, which are in agreement with the luminosity-temperature relation for high-redshift clusters. This is the first detection of a bright X-ray cluster around a luminous (L_bol ~1e47 erg/sec) CSS quasar at high redshift and only the fifth z>1 X-ray cluster detected. We find that the CSS radio source is highly overpressured with respect to the thermal cluster medium by about 3 orders of magnitude. This provides direct observational evidence that the radio source is not thermally confined as posited in the ``frustrated'' scenario for CSS sources. Instead, it appears that the radio source may be young and we are observing it at an early stage of its evolution. In that case the radio source could supply the energy into the cluster and potentially prevent its cooling.

description: Using a Dirac-matrix substitution rule, applied to the electric charge, the anomalous magnetic moments of fermions are incorporated in local form in the two-body relativistic wave equations of constraint theory. The structure of the resulting potential is entirely determined, up to magnetic type form factors, from that of the initial potential descibing the mutual interaction in the absence of anomalous magnetic moments. The wave equations are reduced to a single eigenvalue equation in the sectors of pseudoscalar and scalar states ($j=0$). The requirement of a smooth introduction of the anomalous magnetic moments imposes restrictions on the behavior of the form factors near the origin, in $x$-space. The nonrelativistic limit of the eigenvalue equation is also studied.

Measurement of prompt photons with associated jets in photoproduction at HERA

description: The photoproduction of prompt photons, together with an accompanying jet, has been studied in ep collisions at a centre-of-mass energy of 318 GeV with the ZEUS detector at HERA using an integrated luminosity of 77 pb-1. Cross sections were measured for the transverse energy of the photon and the jet larger than 5 and 6 GeV, respectively. The differential gamma+jet cross sections were reconstructed as functions of the transverse energy, pseudorapidity and x_gamma^obs, the fraction of the incoming photon momentum taken by the photon-jet system. Predictions based on leading-logarithm parton-shower Monte Carlo models and next-to-leading-order (NLO) QCD generally underestimate the cross sections for the transverse energies of prompt photons below 7 GeV, while the kT-factorisation QCD calculation agrees with the data better. When the minimum transverse energy of prompt photons is increased to 7 GeV, both NLO QCD and the kT-factorisation calculations are in good agreement with the data.

description: A common assumption in sexual selection studies is that receivers decode signal information similarly. However, receivers may vary in how they rank signallers if signal perception varies with an individual's sensory configuration. Furthermore, receivers may vary in their weighting of different elements of multimodal signals based on their sensory configuration. This could lead to complex levels of selection on signalling traits. We tested whether multimodal sensory configuration could affect preferences for multimodal signals. We used brown-headed cowbird (Molothrus ater) females to examine how auditory sensitivity and auditory filters, which influence auditory spectral and temporal resolution, affect song preferences, and how visual spatial resolution and visual temporal resolution, which influence resolution of a moving visual signal, affect visual display preferences. Our results show that multimodal sensory configuration significantly affects preferences for male displays: females with better auditory temporal resolution preferred songs that were shorter, with lower Wiener entropy, and higher frequency; and females with better visual temporal resolution preferred males with less intense visual displays. Our findings provide new insights into mate-choice decisions and receiver signal processing. Furthermore, our results challenge a long-standing assumption in animal communication which can affect how we address honest signalling, assortative mating and sensory drive.

description: The bootstrap programme for finding exact S-matrices of integrable quantum field theories with N=1 supersymmetry is investigated. New solutions are found which have the same fusing data as bosonic theories related to the classical affine Lie algebras. When the states correspond to a spinor spot of the Dynkin diagram they are kinks which carry a non-zero topological charge. Using these results, the S-matrices of the supersymmetric O($2n$) sigma model and sine-Gordon model can be shown to close under the bootstrap.

description: The predicted mass function of dark matter halos is essential in connecting observed galaxy cluster counts and models of galaxy clustering to the properties of the primordial density field. We determine the mass function in the concordance $Λ$CDM cosmology, as well as its uncertainty, using sixteen $1024^3$-particle nested-volume dark-matter simulations, spanning a mass range of over five orders of magnitude. Using the nested volumes and single-halo tests, we find and correct for a systematic error in the friends-of-friends halo-finding algorithm. We find a fitting form and full error covariance for the mass function that successfully describes the simulations' mass function and is well-behaved outside the simulations' resolutions. Estimated forecasts of uncertainty in cosmological parameters from future cluster count surveys have negligible contribution from remaining statistical uncertainties in the central cosmology multiplicity function. There exists a potentially non-negligible cosmological dependence (non-universality) of the halo multiplicity function.

Previous mass shifts have been observed at CERN-LEBC-EHS and CERN-LEP. We will show that phase space does not account for the $ρ(770)^0$ mass shift measured at RHIC, CERN-LEBC-EHS and CERN-LEP and conclude that there are significant scattering interactions in $p+p$ collisions.

Automated Pictograph Enhancement of Discharge Instructions: Impact on Recall and Satisfaction
Creators: name: Hill, Brent D.
Publisher: name: University of Utah
Year: 2019

description: Hospital discharge instructions are critical for a patient's posthospitalization recovery. When patients are discharged to home they frequently have to manage wound/incision care, change dressings, take medications, modify activities, follow specialized diets and recognize signs or symptoms that require medical attention. Unfortunately, conditions of hospitalization, effects of illness on cognition, and low health literacy impact a patient's ability to understand discharge instructions. Two studies were completed for this dissertation research. The first was conducted to understand how discharge instructions are created and used by healthcare professionals and by patients. Semistructured interviews were conducted with 5 nurses and 5 doctors who work at the University of Utah Hospital Cardiovascular Medical Unit and 5 patients recently hospitalized on this unit. Coded interview segments were analyzed to reveal themes, which converged with discharge instruction literature, that were then developed as strategies to improve discharge instructions. Strategies included the modification of content through text simplification to improve patient comprehension, the enhancement of readability with logical formatting, the use of discharge instructions to provide consistent information to the patient and the inclusion of pictures or illustrations. The second study was a randomized controlled trial with aims to evaluate the effect of standard versus pictograph-enhanced discharge instructions on immediate and delayed patient recall of the content of and patient satisfaction with their discharge instructions. Participants were randomly assigned to receive standard (n = 71) or pictograph-enhanced (n = 73) discharge instructions and were asked to recall the content of their instructions at discharge and 1 week post discharge. Patients who received pictograph-enhanced discharge instructions recalled more of their instructions at discharge than those who received standard discharge instructions, (t(142) = -3.1, p < .01), and were also more satisfied with the ease of understanding discharge instructions one week after hospital discharge than those who received standard discharge instructions (z(142) = -2.4, p = .016). A multifaceted, comprehensive approach is essential to assist patients through the transition from hospital to self-care. The results of these studies, to improve discharge instruction creation and enhance their understandability, provide interventions that can serve an important role in such an approach.

description: The non-Abelian analog of the classical Coulomb gas is discussed. The statistical mechanics of arrays of classical particles which transform under various representations of a non-Abelian gauge group and which interact through non-Abelian electric fields are considered. The problem is formulated on the lattice and, for the case of adjoint charges, it is solved in the large N limit. The explicit solution exhibits a first order confinement-de-confinement phase transition with computable properties. In one dimension, the solution has a continuum limit which describes 1+1-dimensional quantum chromodynamics (QCD) with heavy adjoint matter.

Benzodiazepines, Health Services Utilization, and Suicide in Veterans with Posttraumatic Stress Disorder

Epidemiology

description: Posttraumatic stress disorder (PTSD) is a trauma and stressor-related disorder that occurs after exposure to a traumatic event. Veterans are at the greatest risk of developing PTSD. Although benzodiazepines are not recommended for the treatment of PTSD, they are still commonly prescribed to veterans. The overall distribution of therapies in the 1,134,201 cohort with PTSD is similar to that outlined in the 2010 Veterans Affairs Posttraumatic Stress Disorder Clinical Practice Guidelines. However, after the first-line psychotherapies and selective serotonin reuptake inhibitors (SSRIs), the not recommended benzodiazepines (7.07%) and atypical antipsychotics (7.53%) have the highest prevalence. The third most frequent overlapping therapy includes benzodiazepines in conjunction with SSRIs, although this percentage is only 0.49. In order to evaluate the association between benzodiazepines and health outcomes, 1:2 propensity score (PS) matching was employed to create a balanced cohort. Plots of standardized differences and distributions of propensity scores indicated that 1:2 PS matching eliminated observable differences (in confounders and risk factors) between benzodiazepines users and nonusers. The final cohort included a total of 81,831 benzodiazepine users and 161,662 nonusers for a total size of 242,493 veterans with PTSD. Generalized linear models and Cox proportional hazards models were used to assess health outcomes. Other than substance abuse outpatient visits (which was higher but statistically insignificant), benzodiazepine users had significantly higher incidence rate ratios for all health care visits. This includes hospitalizations (1.27), ED (1.16), general outpatient (1.18), total mental outpatient (1.37), and mental outpatient visits (1.48). With an outcome of suicide as cause of death, the statistically significant hazard ratio between benzodiazepine users and nonusers is 2.73, thus demonstrating significant elevation in the risk of suicide. The overall evidence from this study reveals that benzodiazepines are not uncommonly prescribed for patients with PTSD and that they are associated with greater health care utilization and suicide outcomes. Most importantly, this study strengthens the evidence against the use of benzodiazepines in veterans with PTSD and that clinicians should consider the benefits and risks - especially the almost three-fold increase in suicide death - when ultimately prescribing this pharmacotherapy.

description: We present an analysis of the constraining power of future measurements of the Integrated Sachs-Wolfe (ISW) effect on models of the equation of state of dark energy as a function of redshift, w(z). To achieve this, we employ a new parameterization of w, which utilizes the mean value of w(z) () as an explicit parameter. This helps to separate the information contained in the estimation of the distance to the last scattering surface (from the CMB) from the information contained in the ISW effect. We then use Fisher analysis to forecast the expected uncertainties in the measured parameters from future ISW observations for two models of dark energy with very different time evolution properties. For example, we demonstrate that the cross-correlation of Planck CMB data and LSST galaxy catalogs will provide competitive constraints on w(z), compared to a SNAP-like SNe project, for models of dark energy with a rapidly changing equation of state (e.g. 'Kink' models). Our work confirms that, while SNe measurements are more suitable for constraining variations in w(z) at low redshift, the ISW effect can provide important independent constraints on w(z) at high z.

description: We introduce a new class of evaluation linear codes by evaluating polynomials at the roots of a suitable trace function. We give conditions for self-orthogonality of these codes and their subfield-subcodes with respect to the Hermitian inner product. They allow us to construct stabilizer quantum codes over several finite fields which substantially improve the codes in the literature and that are records at [http://www.codetables.de] for the binary case. Moreover, we obtain several classical linear codes over the field $\mathbb{F}_4$ which are records at [http://www.codetables.de].

Bereaved Family Members' and Hospice Nurses' Perspectives of Transitions to and Between Residential Facilities for the Dying Elderly
Creators: name: Martz, Camille (Kimi)
Publisher: name: University of Utah
Year: 2019

description: Care transitions for elderly family members enrolled in hospice care to and between home, Assisted Living Facilities (ALF), and Nursing Homes (NH) are fraught with distressing emotions and suffering for both the elderly persons and their families. The purpose of this study was to explore how bereaved families, after the death of their loved one, experienced and perceived these care transitions. Hospice nurses also participated in the study, to provide their perceptions of the end-of-life transition. Glaserian grounded theory (GT) was used to systematically generate theory from the data. Thirty-nine unstructured interviews were conducted with family members (n=14), hospice nurses (n=13), an ALF nurse (n=1), and social workers (n=2). Additional interviews were conducted with family and hospice nurses (n=5) and theoretical group interviews were also conducted (n=4). Data were coded using interpretive, axial, and selective coding. Analysis commenced concurrently utilizing GT principles of constant comparative method as well as memoing. A theoretical model was developed of the stages of the basic social psychological process of Living Through Care Transitions of the Dying Elderly: The Changing Nature of Guilt in Family Caregivers. Findings indicated that guilt escalated during the initial stages of the transfer, and was mitigated by achieving what family members deemed as a "good" death. The experiences and perceptions of the hospice nurses were identified during each phase of the care transition. Results revealed the hospice nurses role in alleviating guilt iv for the family caregivers was by supporting the transition through advocating, navigating the complexities of both facility systems and families, and especially coaching during the dying process, which was seen as the critical support for families during that stage. The findings provided new insight into the nature of guilt and its resolution in bereavement through the attributes of a "good" death. If a "good" death was not achieved, guilt appeared to linger; however, this needs further study. Furthermore, findings also provided educational stage-specific implications for hospice nurses supporting family caregiving through difficult care transitions. Implications of this research also highlight significant issues that affect families caring for older adults that can influence public policy.

description: The model of a memristor-based oscillator with cubic nonlinearity is studied. The considered system has infinitely many equilibrium points, which build a line of equilibria in the phase space. Numerical modeling of the dynamics is combined with bifurcational analysis. It is shown that oscillation excitation has distinctive features of the supercritical Andronov--Hopf bifurcation and can be achieved by changing of a parameter value as well as by variation of initial conditions. Therefore the considered bifurcation is called Andronov-Hopf bifurcation with and without parameter.

Automated Approaches for Snow and Ice Cover Monitoring Using Optical Remote Sensing
Creators: name: Selkowitz, David James
Publisher: name: University of Utah
Year: 2019
Subjects: Geography

description: Snow and ice cover exhibits a high degree of spatial and temporal variability. Data from multispectral optical remote sensing instruments such as Landsat are an underutilized resource that can extend our ability for mapping these phenomena. High resolution imagery is used to demonstrate that even at finer spatial resolutions (below 100 m), pixels with partial snow cover are common throughout the year and nearly ubiquitous during the meltout period. This underscores the importance of higher spatial resolution datasets for snow cover monitoring as well as the utility of fractional snow covered area (fSCA) monitoring approaches. Landsat data are used to develop a fully automated approach for mapping persistent ice and snow cover (PISC). This approach relies on the availability of numerous Landsat scenes, an improved technique for automated cloud cover mapping, and a series of automated postprocessing routines. Validation at 12 test sites suggest that the automated PISC mapping approach provides a good approximation of debris-free glacier extent across the Arctic. The PISC mapping approach is then used to produce the first single-source, temporally well-constrained (2010-2014) map of PISC across the conterminous western U.S. The Landsat-derived PISC map is more accurate than both a previously published dataset based on aerial photography acquired during the 1960s, 1970s and 1980s and the National Land Cover Database (NLCD) 2011 extent of perennial snow and ice cover. Further analysis indicates differences between the newly developed Landsat-derived PISC dataset and the previously published glacier dataset can likely be attributed to changes in the extent of PISC over time. Finally, in order to map mean annual snow cover persistence across the entire landscape, we implement a novel canopy adjustment approach designed to improve the accuracy of Landsat-derived fSCA in forested areas. In situ observations indicate canopy-adjusted snow covered area calculated from all available Landsat scenes can provide an accurate estimate of mean annual snow cover duration. The work presented here lays the groundwork for addressing scientific questions regarding the spatial and temporal variability of snow cover, snow accumulation and ablation processes, and the impact of changes in snow cover on physical and ecological systems.

description: Risk-based authentication (RBA) is used in online services to protect user accounts from unauthorized takeover. RBA commonly uses contextual features that indicate a suspicious login attempt when the characteristic attributes of the login context deviate from known and thus expected values. Previous research on RBA and anomaly detection in authentication has mainly focused on the login process. However, recent attacks have revealed vulnerabilities in other parts of the authentication process, specifically in the account recovery function. Consequently, to ensure comprehensive authentication security, the use of anomaly detection in the context of account recovery must also be investigated.
 This paper presents the first study to investigate risk-based account recovery (RBAR) in the wild. We analyzed the adoption of RBAR by five prominent online services (that are known to use RBA). Our findings confirm the use of RBAR at Google, LinkedIn, and Amazon. Furthermore, we provide insights into the different RBAR mechanisms of these services and explore the impact of multi-factor authentication on them. Based on our findings, we create a first maturity model for RBAR challenges. The goal of our work is to help developers, administrators, and policy-makers gain an initial understanding of RBAR and to encourage further research in this direction.

We show that the only pure states having non-negative W for all such functions are stabilizer states, as conjectured by one of us [Phys. Rev. A 71, 042302 (2005)]. We also show that the unitaries preserving non-negativity of W for all definitions of W form a subgroup of the Clifford group. This means pure states with non-negative W and their associated unitary dynamics are classical in the sense of admitting an efficient classical simulation scheme using the stabilizer formalism.

description: We used a mixed-methods design to test a novel weight bias intervention and understand current attitudes toward people with higher weight and weight-inclusive care among medical students (N = 80). The intervention was embedded in curriculum and uniquely focused on delegitimising the use of weight as a heuristic for health. Almost half of participants (43.8%) responded to both pre- and post-intervention surveys. These participants found the intervention acceptable; and reported significant pre-post reductions in weight bias and endorsement of using weight as a heuristic for health. Less engaged participants reported significantly greater endorsement of using weight as a heuristic for health at pre-intervention. One central theme emerged from pre-intervention qualitative responses, related to how medical students scoped both the problem and the solution. This consisted of three sub-themes: (1) problematizing the system and clinician (and their weight bias), (2) problematizing the patient (who was responsible for their own health), and (3) problematizing the medical condition (weight and health behaviors as problems for the clinician to solve). Participants often showed evidence of several and sometimes contradictory ways of problem-scoping. Problematizing the patient, including weight-stigmatizing assumptions, was particularly pronounced among less engaged participants (i.e. those who did not complete the post-survey). Findings suggest that the intervention may be acceptable and effective in reducing weight bias in medical students who already have lower levels of bias than their peers. Qualitative findings suggest that, even when medical students recognize the harmful impacts of weight stigma and the benefits of weight-inclusive care, approaches to care may remain weight-centric. Together, the findings suggest a key challenge for weight bias reduction among medical students lies in addressing problem-scoping that may encourage weight bias and weight-centric care, and reaching the population most in need of intervention – students with high levels of weight bias.

description: Fovea centralis is a depression located in the back of the primate retina. This region is crucial for sharp central vision. Age Related Macular Degeneration (AMD) is a debilitating disease that affects several million people in the world. In this disease, the retina and RPE surrounding the fovea undergoes degeneration, thereby compromising visual acuity. The fovea contains significant amounts of three carotenoids - lutein, zeaxanthin, and meso-zeaxanthin. Carotenoids are plant-derived pigment molecules. Vertebrates are unable to synthesize these compounds de novo, and have to obtain these through the diet. Carotenoids protect the foveal region from oxidative stress, light damage, and improves vision. Carotenoid supplementation is shown to alter the course of AMD. Hundreds of carotenoids are present in nature, and the regular human diet consumes about 50 of these. Among these, only 15 are absorbed by the gut and present in the serum. However, only lutein, zeaxanthin, and meso-zeaxanthin are present in the retina. Retinal concentrations of these carotenoids are 5000 times greater than observed levels in the serum, suggesting a very specific transport mechanism into the retina. There are gaps in our knowledge of the mechanisms involved in carotenoid transport into the eye. meso-Zeaxanthin is a retina-specific carotenoid that is rarely encountered in nature. No dietary sources of meso-zeaxanthin are identified. At the foveal pit, there are equal amounts of lutein, zeaxanthin, and meso-zeaxanthin. However, meso-zeaxanthin is absent in the peripheral retina. The mechanism by which meso-zeaxanthin is produced in the eye and the physiological significance of its presence is not understood .

Biochemical and Structural Studies of the Transcription Elongation Factor SPT6 and Its Biding Partners
Creators: name: Sdano, Matthew A.
Publisher: name: University of Utah
Year: 2019

description: Production of a functional protein requires coordination and regulation of many factors that control different cellular processes. One of these factors, Spt6, is a highly conserved nuclear protein that has roles in several facets of gene expression. Spt6 is best known for its ability to chaperone histones and modulate chromatin structure, but it also functions as a transcription elongation factor and in mRNA processing and export. Spt6 co-localizes with elongating RNA polymerase II (RNAPII) where it reassembles nucleosomes following RNAPII passage in order to repress aberrant transcription initiation. Furthermore, Spt6 directly stimulates RNAPII elongation rates and coordinates co-transcriptional mRNA processing. Despite the wealth of functional data that implicate Spt6 in these processes, little is known about the mechanistic basis for these activities. In order to gain mechanistic understanding of Spt6 activities, the work presented in this thesis focused on biochemical, structural, and functional characterization of Spt6 interactions with other proteins. These studies reveal the true Spt6 binding site on RNAPII, identify Tom1 as a novel Spt6 binding partner, and demonstrate a specific interaction between Spt6 and histones H3-H4 that is competitive with DNA. The elucidation of the authentic Spt6 binding site on RNAPII has allowed us to develop tools to probe the mechanism of Spt6 recruitment to transcribed regions. Identification of Tom1 iv as a phosphorylated Spt6 binding partner provides a physical link to potential Spt6 functions such as mRNA export, cell cycle regulation, and regulation of histone levels. Characterization of the interaction with H3-H4 brings us closer to a mechanistic understanding of the histone chaperone activity of Spt6. Overall, the data presented in this work advance our knowledge of the interactions that regulate Spt6 function and will aid future studies to further dissect the mechanistic basis for Spt6 roles in gene expression.

description: Interest has arisen regarding different dietary approaches, namely prescriptive vs non-dieting approaches. Nonetheless, evidence on which individual factors orient professionals toward either approach is currently lacking for dietetics students and registered dietitians (RDN). For this reason, the present study aimed at investigating personal and interpersonal factors associated with the adoption of such approaches in dietary practice. This cross-sectional observational study involved 174 participants through an online survey (response rate 74.41%, n = 128). Participants were recruited from two universities in Italy, encompassing both RDNs and dietetics students. The sample was then divided by self-reported dietary approach orientation and group differences were explored. Personal (such as previous history of dieting, personality factors, intuitive eating, eating experiences) and interpersonal factors (like areas of work interest, years of clinical expertise) potentially influencing dietary orientation were investigated. Group differences were estimated by Analysis of Covariance (ANCOVA) for continuous variables, after adjustment for age and gender, and by Chi-squared tests for categorical variables. Moreover, network structures for psychometric variables were estimated for both groups, employing a mixed graphical model, and computing a comparison between groups after bootstrapping (edge invariance test, n = 5,000). Results showed that openness to experience (F-value: 3.989 p-value: <0.05) and intuitive eating (F-value: 9.836, p-value: <0.01) were higher among participants which oriented toward non-dieting approaches. RDNs with more years of clinical experience (p-value: 0.004) and working within the field of eating disorders (p-value: <0.001) were more likely to be oriented toward non-dieting approaches. Current findings suggest that personal and interpersonal factors shape dietary orientations.

description: Machine learning models are vulnerable to maliciously crafted Adversarial Examples (AEs). Training a machine learning model with AEs improves its robustness and stability against adversarial attacks. It is essential to develop models that produce high-quality AEs. Developing such models has been much slower in natural language processing (NLP) than in areas such as computer vision. This paper introduces a practical and efficient adversarial attack model called SSCAE for \textbf{S}emantic, \textbf{S}yntactic, and \textbf{C}ontext-aware natural language \textbf{AE}s generator. SSCAE identifies important words and uses a masked language model to generate an early set of substitutions. Next, two well-known language models are employed to evaluate the initial set in terms of semantic and syntactic characteristics. We introduce (1) a dynamic threshold to capture more efficient perturbations and (2) a local greedy search to generate high-quality AEs. As a black-box method, SSCAE generates humanly imperceptible and context-aware AEs that preserve semantic consistency and the source language's syntactical and grammatical requirements. The effectiveness and superiority of the proposed SSCAE model are illustrated with fifteen comparative experiments and extensive sensitivity analysis for parameter optimization. SSCAE outperforms the existing models in all experiments while maintaining a higher semantic consistency with a lower query number and a comparable perturbation rate.

description: We derive optimal schemes for preparation and estimation of relational degrees of freedom between two quantum systems. We specifically analyze the case of rotation parameters representing relative angles between elements of the SU(2) symmetry group. Our estimation procedure does not assume prior knowledge of the absolute spatial orientation of the systems and as such does not require information on the underlying classical reference frame in which the states are prepared.
