description: We report measurements of B meson decays to two kaons using 250/fb of data collected with the Belle detector at the KEKB asymmetric energy e+ e- collider. We find evidence of signals in B+ -> K0(bar) K+ and B0 -> K0 K0(bar) with significances of 3.0 sigma and 3.5 sigma, respectively. The corresponding branching fractions are measured to be BF(B+ -> K0(bar) K+) = (1.0+-0.4+-0.1) x 10^-6 and Br(B0 -> K0 K0(bar)) = 0.8+-0.3+-0.1) x 10^-6. These decay modes are examples of hadronic b -> d transitions. No signal is observed in the decay B0 -> K+ K- and we set an upper limit of 3.7 x 10^-7 at 90% confidence level.

description: In a micro ring of a superconductor with a spin-triplet equal-spin pairing state, a fluxoid, a combined object of magnetic flux and circulating supercurrent, can penetrate as half-integer multiples of the flux quantum. A candidate material to investigate such half-quantum fluxoids is Sr$_\mathsf{2}$RuO$_\mathsf{4}$. We fabricated Sr$_\mathsf{2}$RuO$_\mathsf{4}$ micro rings using single crystals and measured their resistance behavior under magnetic fields controlled with a three-axes vector magnet. Proper Little-Parks oscillations in the magnetovoltage as a function of an axially applied field, associated with fluxoid quantization are clearly observed, for the first time using bulk single crystalline superconductors. We then performed magnetovoltage measurements with additional in-plane magnetic fields. By carefully analyzing both the voltages $V_+$ ($V_-$) measured at positive (negative) current, we find that, above an in-plane threshold field of about 10 mT, the magnetovoltage maxima convert to minima. We interpret this behavior as the peak splitting expected for the half-quantum fluxoid states.

description: Topological aspects represent currently a boosting area in condensed matter physics. Yet there are very few suggestions for technical applications of topological phenomena. Still, the most important is the calibration of resistance standards by means of the integer quantum Hall effect. We propose modifications of samples displaying the integer quantum Hall effect which render the tunability of the Fermi velocity possible by external control parameters such as gate voltages. In this way, so far unexplored possibilities arise to realize devices such as tunable delay lines and interferometers.

description: We study initial-state radiation events, $e^+e^- \to γ_{ISR}π^+π^-J/ψ$, with data collected with the BaBar detector. We observe an accumulation of events near 4.26 GeV/$c^2$ in the invariant-mass spectrum of $π^+π^-J/ψ$. Fits of the mass spectrum indicate that a broad resonance with a mass of about 4.26 GeV/$c^2$ is required to describe the observed structure. The presence of additional narrow resonances cannot be excluded. The fitted width of the broad resonance is 50 to 90 MeV/$c^2$, depending on the fit hypothesis.

description: Single-photon detection is an essential component in many experiments in quantum optics, but remains challenging in the microwave domain. We realize a quantum non-demolition detector for propagating microwave photons and characterize its performance using a single-photon source. To this aim we implement a cavity-assisted conditional phase gate between the incoming photon and a superconducting artificial atom. By reading out the state of this atom in single shot, we reach an internal photon detection fidelity of 71%, limited by the coherence properties of the qubit. By characterizing the coherence and average number of photons in the field reflected off the detector, we demonstrate its quantum non-demolition nature. We envisage applications in generating heralded remote entanglement between qubits and for realizing logic gates between propagating microwave photons.

description: This is a contribution to the formalization of the concept of agents in multivariate Markov chains. Agents are commonly defined as entities that act, perceive, and are goal-directed. In a multivariate Markov chain (e.g. a cellular automaton) the transition matrix completely determines the dynamics. This seems to contradict the possibility of acting entities within such a system. Here we present definitions of actions and perceptions within multivariate Markov chains based on entity-sets. Entity-sets represent a largely independent choice of a set of spatiotemporal patterns that are considered as all the entities within the Markov chain. For example, the entity-set can be chosen according to operational closure conditions or complete specific integration. Importantly, the perception-action loop also induces an entity-set and is a multivariate Markov chain. We then show that our definition of actions leads to non-heteronomy and that of perceptions specialize to the usual concept of perception in the perception-action loop.

description: We study synchrotron self-inverse Compton radiation from a reverse-shocked fireball. If the inverse Compton process dominates the cooling of shocked electrons, an X-ray flare produced by the first order Compton scattering would emerge in the very early afterglow phase, with the bulk of the shock energy radiated in the second order scattering component at 10-100 MeV. The dominance of inverse Compton cooling leads to the lack of prompt optical flashes. We show that for plausible parameters this scattering process can produce an X-ray flare with a relative amplitude change by a factor of several. Flares with a larger amplitude and multiple X-ray flares in a single event are likely to be produced by another mechanism (e.g. internal shocks).

Impacts of Topographic Shading on Surface Energy Balance of High Mountain Asia Glaciers
Creators: name: Olson, Matthew Howard
Publisher: name: University of Utah
Year: 2019
Subjects: Climate Change

description: Topographic shading involves two components: shaded relief and cast shadowing. Shaded relief occurs from self-shadowing due to the slope and aspect of a given location; cast shadowing involves projecting shade from nearby terrain onto an adjacent surface. The combined effect of topographic shading plays a fundamental role in determining surface energy balance for glacier ice. However, this parameter has been oversimplified or incorrectly incorporated in some past studies. Here we develop a topographic solar radiation model to examine the variability in mean irradiance throughout the melt season due to topographic shading and combined slope and aspect. We utilize the 30-meter resolution ASTER GDEM and multihour solar geometry to simulate topographic shading on two glaciers of differing morphologies in regions of contrasting terrain. We test the sensitivity of shading to valley-aspect and latitude for the same two glaciers, and observe patterns in these parameters for a suite of glaciers across High Mountain Asia (HMA). Our results show that topographic shading significantly alters the potential direct clear-sky solar radiation received at the surface for valley glaciers in HMA. Additionally, contrary to the findings of some previous studies, we find that shading can be extremely impactful in the ablation zone of some valley glaciers, particularly for north- and south-facing valleys. A daily mean change in irradiance of more than -70 Wm-2 due to cast shadowing is found in the ablation zones of some HMA glaciers. Cast shadowing is the dominant mechanism in determining total shading for valley glaciers in parts of HMA, especially at lower elevations. Although shading has some predictable characteristics, it is overall extremely variable between glacial valleys, and therefore very difficult to parameterize. We use a modified temperature-index model that includes potential clear-sky irradiance to calculate melt for one selected glacier. Excluding topographic shading for this glacier results in an overestimation of total summer melt in the ablation zone by up to 10%. This demonstrates that topographic shading is not only an important factor contributing to surface energy balance, but can also influence the mass balance of glaciers throughout HMA.

description: We utilize nanoscale spin valves with Pt spacer layers to characterize spin scattering in Pt. Analysis of the spin lifetime determined from our measurements indicates that the extrinsic Elliot-Yafet spin scattering is dominant at room temperature, while the intrinsic Dyakonov-Perel mechanism dominates at cryogenic temperatures. The significance of the latter is supported by the suppression of spin relaxation in Pt layers interfaced with a ferromagnet, likely caused by the competition between the effective exchange and spin-orbit fields.

Impact of Dietary Magnesium upon Insulin Sensitivity, Vascular Function, and Metabolic Complications During Development of Type 2 Diabetes

description: Background: Epidemiological data associates low magnesium (Mg) intake with greater risk of metabolic syndrome/diabetes, and Mg status is often compromised in diabetic patients. It remains unclear whether low Mg consumption may exacerbate the metabolic disruptions that occur during diabetes. Objective: We hypothesized low dietary Mg during the development of diabetes would alter metabolic rate, and worsen glucose tolerance/insulin sensitivity. Methods: Three cohorts (n = 8 each) of 8-week-old TallyHo (TH) mice that develop Type 2 Diabetes by 16 weeks of age were fed special diets for 8 weeks. Group 1: TH + Low Mg diet (L-Mg, 100mg Mg Oxide/kg chow). Group 2: TH + Standard Mg diet (S-Mg, 500mg Mg Oxide/kg chow). Group 3: TH + High Mg diet (H-Mg, 1000mg Mg Bisglycinate/kg chow). Age-matched male C57BL/6J mice fed standard diets served as controls (Con, n = 8, 500mg Mg Oxide/kg chow). Results: Energy expenditure was lowest (p < 0.05) in L-Mg vs. all other groups. Insulin tolerance test (AUC, glucose mg/dL), indicated insulin resistance (p < 0.05) in L-Mg (12394 ± 2344) vs. Con (3866 ± 2344), and a trend (p = 0.052) indicating greater insulin resistance in S-Mg (10429 ± 2193) vs. Con. However, insulin tolerance was normalized in H-Mg (7838 ± 2344) vs. Con. QUICKI index indicated that all groups were insulin resistant (p < 0.05) compared to Con (0.585 ± 0.14). However, L-Mg (0.403 ± 0.15) had greater (p < 0.05) insulin resistance than S-Mg (0.462 ± 0.17) and H-Mg (0.454 ± 0.15). Insulin stimulated phosphorylation of hepatic insulin receptor was similar among all groups, whereas Akt phosphorylation was reduced (p < 0.05) in all diabetic mice regardless of Mg intake. Conclusions: Low dietary Mg intake reduces oxygen consumption and energy expenditure, and worsens insulin sensitivity in diabetic mice. Supplemental Mg can partially reduce fasting glucose and improve insulin tolerance, but could not be attributed to an improvement in hepatic insulin signaling.
Strange star equations of state revisited

description: Motivated by recent suggestions that strange stars can be responsible for glitches and other observational features of pulsar, we review some possible equations of state and their implications for models of neutron, hybrid and strange stars. We consider the MIT bag model and also strange matter in the color-flavored-locked phase. The central energy densities for strange stars are higher than the central densities of ordinary neutron stars. Strange stars are bound by the strong force and so can also rotate much faster than neutron stars. These results are only weakly dependent on the model used for the quark matter. If just one of the existing mass to radius ratio constraint is valid, most neutron stars equations of state are ruled out, but all the strange stars equations of state presented in this work remain consistent with the constraint.

description: We carry out high resolution simulations of the inner regions of a wide angle wind driven bipolar outflow using an Adaptive Mesh Refinement code. Our code follows H-He gas with molecular, atomic and ionic components and the associated time dependent molecular chemistry and ionization dynamics with radiative cooling. Our simulations explore the nature of the outflow when a spherical wind expands into a rotating, collapsing envelope. We compare with key observational properties of the outflow system of Source I in the BN/KL region. Our calculations show that the wind evacuates a bipolar outflow cavity in the infalling envelope. We find the head of the outflow to be unstable and that it rapidly fragments into clumps. We resolve the dynamics of the strong shear layer which defines the side walls of the cavity. We conjecture that this layer is the likely site of maser emission and examine its morphology and rotational properties. The shell of swept up ambient gas that delineates the cavity edge retains its angular momentum. This rotation is roughly consistent with that observed in the Source I SiO maser spots. The observed proper motions and line-of-sight velocity are approximately reproduced by the model. The cavity shell at the base of the flow assumes an X-shaped morphology which is also consistent with Source I. We conclude that the wide opening angle of the outflow is evidence that a wide-angle wind drives the Source I outflow and not a collimated jet.

description: Compact radio galaxies with a GHz-peaked spectrum (GPS) and/or compact-symmetric-object (CSO) morphology (GPS/CSOs) are increasingly detected in the X-ray domain. Their radio and X-ray emissions are affected by significant absorption. However, the locations of the X-ray and radio absorbers are still debated. We investigated the relationship between the column densities of the total ($N_{\mathrm{H}}$) and neutral ($N_{\mathrm{HI}}$) hydrogen to statistically constrain the picture. We compiled a sample of GPS/CSOs including both literature data and new radio data that we acquired with the Westerbork Synthesis Radio Telescope for sources whose X-ray emission was either established or under investigation. In this sample, we compared the X-ray and radio hydrogen column densities, and found that $N_{\mathrm{H}}$ and $N_{\mathrm{HI}}$ display a significant positive correlation, with $N_{\mathrm{HI}} \propto N_{\mathrm{H}}^b$, where $b=0.47$ and $b=0.35$, depending on the subsample. The $N_{\mathrm{H}}$ - $N_{\mathrm{HI}}$ correlation suggests that the X-ray and radio absorbers are either co-spatial or different components of a continuous structure. The correlation displays a large intrinsic spread that we suggest to originate from fluctuations, around a mean value, of the ratio between the spin temperature and the covering factor of the radio absorber, $T_{\rm s}/C_{\rm f}$.

description: Ten years after its discovery at the Tevatron collider, we still know little about the top quark. Its large mass suggests it may play a key role in the mechanism of Electroweak Symmetry Breaking (EWSB), or open a window of sensitivity to new physics related to EWSB and preferentially coupled to it. To determine whether this is the case, precision measurements of top quark properties are necessary. The high statistics samples being collected by the Tevatron experiments during Run II start to incisively probe the top quark sector. This report summarizes the experimental status of the top quark, focusing in particular on the recent measurements from the Tevatron.

Hydrodynamic Interactions and Motion of Bacteria at Low Reynolds Number

description: Microorganism motility supports many features in the microbial world and is closely linked to their abilities to find food, mate, and colonize, which are essential to their survival. While swimming, the organisms interact with their fluid environment in a manner quite different from our common human experience in fluids, making it interesting to understand the physics of such low Reynolds number hydrodynamics. In this dissertation, I discuss four different aspects of locomotion in viscous fluids. We first study the suitable choice of computational method for swimming and pumping with a helical flagellar filament at a low Reynolds number. Comparing the most commonly used approaches to solve Stokes equations numerically, we provide a guideline for the optimal choice of the tuning parameters for a wide helical geometries range balancing the accuracy and computational time expenses. We then study the effect of helical cell bodies on the swimming speed and trajectory by comparing to rod-shaped geometries. We validate our numerical model with experiments from high-frame-rate digital tracking and image processing for both helical and straight mutant (Helicobacter pylori) swimming mucin and broth solution. We find that the helicity of the cell body makes at most a 15% contribution to the additional thrust and change in swimming speed. We also study the single-flagellated bacterial flicks and instabilities due to hook and flagellum flexibilities. We find that dynamic instability initiates bacterial flick and then flexibility of the flagellar filament plays an important role in reorientation of the swimmer. Finally, we consider hydrodynamic interactions of a swimmer with a complex biological environment and other passive particles in viscous fluid. We examine long-range hydrodynamic interactions of a simple swimmer near spherical and filamentous obstacles and find that swimming velocity fluctuation is closely related to the correlations in density and orientations of obstacles. For the hydrodynamic interactions and approach of organisms with passive particles, we find exact solutions for the approach of spherical shapes in the cases that the swimmer is driven by a localized constant force and with distributed propulsion (squirmer model). We study the feasibility of approach and find that an organism can approach any similar size or bigger target compared to the organism's size, but approaching smaller targets depends on the current strength generated by the swimmer.
Hydrolysis of titanic acid in hydrochloric acid solution for synthesis of tio2 powder with controlled particle size: processes, morphology, and kinetics study
Creators: name: Huang, Zhe
Publisher: name: University of Utah
Year: 2019
Subjects: Materials science

description: A method for producing pure titanium dioxide with controlled particle size and morphology has been developed. The TiO2 powder produced by this method can be used as the starting material to produce pure Ti metal powder. In this method, the upgraded Ti-slag (UGS) is used as the starting material. Upgraded Ti-slag is first roasted with NaOH to produce sodium titanate. The roasted product is washed by water to remove alkaline soluble impurities like Si and Al. The titanate is then dissolved into HCl solution and filtered to prepare the solution for hydrolysis of titanic acid. Hydrolysis of titanic acid is performed at different temperatures with varied free acid concentration and equivalent TiO2 concentration. The titanic acid is then calcined to remove combined water to produce TiO 2 powder. The particle size and morphology of the titanic acid particles produced by this method depend strongly on factors including temperature, free acid concentration, equivalent TiO2 concentration, and agitation. To optimize the parameters of the hydrolysis process, a systematic parametric study was conducted. TiO2 powders with different morphology and particle size were obtained. The desired morphology of TiO2 powder is determined to be around 30µm, with a round shape and smooth surface. Porosity was found on the surface of TiO2 particles after calcination. The dependence of particle size and morphology of solid titanic acid particles on those process parameters was studied. The effect of the process parameters on the kinetics of the hydrolysis process were also studied. The mechanisms of nucleation and growth of titanic acid particles during hydrolysis was discussed.

description: There are conflicting findings in the literature regarding the impact of effortful task demands on the availability of automatic semantic priming processes. Woltz and colleagues reported in one experiment that semantic priming effects were eliminated when episodic retrieval demands were added to a sentence completion priming task. This result could reflect sensitivity of automatic priming to effortful processing in general, or it could reflect the impact of changing task set or processing goals. The current experiment tested the general effort explanation in the same sentence completion. A mixed-case manipulation was used to increase attention demands in some target trials. This presumably disrupted the automatic reading process but did not change the processing goals demanded by the task. Response time was slower in the mixed case trials; however, semantic priming was not impacted by the perceptual effort manipulation. This evidence, in combination with previous findings, suggests that automatic priming processes can facilitate performance even under some forms of effortful task demands, and that disruption of priming may depend on the addition of different task goals.
The Impact of Cost Transparency on the Cost of Care Delivery: A Systematic Review

Publisher: name: University of Utah

description: Health care costs in the United States are rising at an alarming rate. Although much of the cost of care is dependent on the decisions of care providers, providers remain largely unaware of those costs. Legislators have passed initiatives aimed at increasing cost transparency, but the impact of cost transparency on the cost of care is uncertain. The purpose of this study was to systematically review trials investigating the impact of cost transparency on the cost of care delivery, identify the factors likely to increase the effectiveness of such interventions, and suggest directions for future research. We searched the Scopus database for relevant studies published up to November 2014. After identifying potentially relevant studies, we performed additional searches for publications citing or cited by the selected studies. This process was repeated until no additional studies were identified. Key characteristics of relevant studies were extracted for analysis. We screened a total of 4,906 articles, 23 of which were included in the final analysis. We identified timing (education prior to the decision vs. feedback following the decision) and medium (electronic vs. nonelectronic) of communication as key factors impacting the effectiveness of the cost transparency intervention. One hundred percent (9 of 9) of "postorder feedback" studies resulted in decreased costs, whereas only 54% (7 of 13) of studies in which cost was communicated prior to the clinical decision ("pre-order education" studies) lowered the cost of care delivery. Eighty-eight percent (14 of iv 16) of nonelectronic studies reduced costs; 29% (2 of 7) of electronic studies reduced costs. Cost transparency can be an effective strategy to reduce utilization of expensive tests or therapies. Intervention strategies that employ nonelectronic media for communication of financial information to providers and that communicate postdecision feedback may be most likely to succeed. The trend in current publications suggests that health care providers may be moving toward the less effective methods of cost transparency, which could hamper cost containment efforts. The strength of these observations is limited by the absence of prospective studies that directly compare the effectiveness of various cost transparency intervention methods. Future studies are needed to verify these findings and to determine the impact of cost transparency in new cost-centric organizations and incentive structures.

description: A conditioned unitary transformation ($90^o$ polarization rotation) is performed at single-photon level. The transformation is realized by rotating polarization for one of the photons of a polarization-entangled biphoton state (signal photon) by means of a Pockel's cell triggered by the detection of the other (idler) photon after polarization selection. As a result, polarization degree for the signal beam changes from zero to the value given by the idler detector quantum efficiency. This result is relevant to practical realization of various quantum information schemes and can be used for developing a new method of absolute quantum efficiency calibration.

description: We describe the structure and implementation of a moving-mesh hydrodynamics solver in the large-scale parallel code, Charm N-body GrAvity solver (ChaNGa). While largely based on the algorithm described by Springel (2010) that is implemented in AREPO, our algorithm differs a few aspects. We describe our use of the Voronoi tessellation library, VORO++, to compute the Voronoi tessellation directly. We also incorporate some recent advances in gradient estimation and reconstruction that gives better accuracy in hydrodynamic solutions at minimal computational cost. We validate this module with a small battery of test problems against the smooth particle hydrodynamics solver included in ChaNGa. Finally, we study one example of a scientific problem involving the mergers of two main sequence stars and highlight the small quantitative differences between smooth particle and moving-mesh hydrodynamics. We close with a discussion of anticipated future improvements and advancements.

description: We study thermal-gravitational instability in simplified models for protogalactic halos using three-dimensional hydrodynamic simulations. The simulations followed the evolution of gas with radiative cooling down to T = 10^4 K, background heating, and self-gravity. Then cooled and condensed clouds were identified and their physical properties were examined in detail. During early stage clouds start to form around initial density peaks by thermal instability. Small clouds appear first and they are pressure-bound. Subsequently, the clouds grow through compression by the background pressure as well as gravitational infall. During late stage cloud-cloud collisions become important, and clouds grow mostly through gravitational merging. Gravitationally bound clouds with mass M_c > ~6 X 10^6 Msun are found in the late stage. They are approximately in virial equilibrium and have radius R_c = \~150 - 200 pc. Those clouds have gained angular momentum through tidal torque as well as merging, so they have large angular momentum with the spin parameter ~ 0.3. The clouds formed in a denser background tend to have smaller spin parameters. We discuss briefly the implications of our results on the formation of protoglobular cluster clouds in protogalactic halos. (abridged)

TeV dark matter and the DAMPE electron excess

description: The recent high energy electron and positron flux observed by the DAMPE experiment indicates possible excess events near 1.4 TeV. Such an excess may be evidence of dark matter annihilations or decays in a dark matter subhalo that is located close to the solar system. We give here an analysis of this excess from annihilations of Dirac fermion dark matter which is charged under a new $U(1)_X$ gauge symmetry. The interactions between dark matter and the standard model particles are mediated the $U(1)_X$ gauge boson. We show that dark matter annihilations from a local subhalo can explain the excess with the canonical thermal annihilation cross section. We further discuss the constraints from the relic density, from the dark matter direct detection, from the dark matter indirect detection, from the cosmic microwave background, and from the particle colliders.

Efficient extraction of quantum Hamiltonians from optimal laboratory data

description: Optimal Identification (OI) is a recently developed procedure for extracting optimal information about quantum Hamiltonians from experimental data using shaped control fields to drive the system in such a manner that dynamical measurements provide maximal information about its Hamiltonian. However, while optimal, OI is computationally expensive as initially presented. Here, we describe the unification of OI with highly efficient global, nonlinear map-facilitated data inversion procedures. This combination is expected to make OI techniques more suitable for laboratory implementation. A simulation of map-facilitated OI is performed demonstrating that the input-output maps can greatly accelerate the inversion process.

description: We present results from the first exposure of a liquid Ar time projection chamber to a neutrino beam. The data have been collected in 1997 with a 50 liter ICARUS-like chamber located between the CHORUS and NOMAD experiment at the CERN West Area Neutrino Facility. We focus on the analysis of quasi-elastic interactions; despite the limited size of the detector, nuclear effects beyond Fermi motion and Pauli blocking have been observed as perturbations to the pure quasi-elastic kinematics.

Quantum and Classical Tradeoffs

description: We propose an approach for quantifying a quantum circuit's quantumness as a means to understand the nature of quantum algorithmic speedups. Since quantum gates that do not preserve the computational basis are necessary for achieving quantum speedups, it appears natural to define the quantumness of a quantum circuit using the number of such gates. Intuitively, a reduction in the quantumness requires an increase in the amount of classical computation, hence giving a ``quantum and classical tradeoff''. In this paper we present two results on this direction. The first gives an asymptotic answer to the question: ``what is the minimum number of non-basis-preserving gates required to generate a good approximation to a given state''. This question is the quantum analogy of the following classical question, ``how many fair coins are needed to generate a given probability distribution'', which was studied and resolved by Knuth and Yao in 1976. Our second result shows that any quantum algorithm that solves Grover's Problem of size n using k queries and l levels of non-basis-preserving gates must have k*l=Ω(n).
