description: Dating apps are a novel means of delivering HIV prevention messages. Young black sexual minority men (YBSMM) app users are at high risk for HIV and could benefit from frequent testing. Understanding testing behaviors among YBSMM is critical to inform tailored prevention interventions. We analyzed testing behaviors of 273 YBSMM, comparing typical testing frequency between app users and non-users using odds ratios. Overall, testing rates were high. App users were more likely than non-users to test at least every 12 months. App-using YBSMM exhibit high compliance with testing guidelines, which may indicate future successful uptake of biomedical preventions, such as Pre-Exposure Prophylaxis.

description: To establish a combined method of qualitative and quantitative for evaluating cultivated land fertility, visually and accurately reflect cultivated land fertility, and provide the basis for scientific management and sustainable utilization of cultivated land resources, we analyzed the cultivated land fertility in Yongning County of Ningxia Hui Autonomous Region. Based on GIS, we adopted Delphi approach, cluster analysis, analytic hierarchy process (AHP) and fuzzy evaluation. Results show that the fertility of cultivated land could be divided into 6 grades and the area of the first, second, third, fourth, fifth and sixth grades was 70 585.91 hm2, 219 047.67 hm2, 230 101.46 hm2, 132 079.65 hm2, 39 328.14 hm2 and 35 502.53 hm2 respectively, accounting for 9.71%, 30.15%, 31.67%, 18.18%, 5.41% and 4.89% separately. In line with major existing problems in utilization of cultivated land, we proposed some suggestions for rationally utilizing and improving cultivated land resources.

description: In recent years, unprecedented progress in observational cosmology has revealed a great deal of information about the formation and evolution of structures in the universe. This, in turn, has raised many challenging issues for the theorists. In the thesis, we have addressed two such key issues, namely, (a) the formation of baryonic structures and (b) the nature of dark matter and dark energy and the limitations in determining their nature from observations. The main results from the thesis are: (i) The baryons in the intergalactic medium at redshifts z \sim 2.5 can be modelled (both analytically and semi-analytically) by accounting for the non-linearities in the density field through lognormal approximation. Our results agree with observations, and can be used for constraining parameters related to the baryons. (ii) A simple model based on baryon conservation, along with observational estimates of cosmic star formation rate, correctly predicts the abundance of damped Lyman-alpha systems in the universe. (iii) The redshift distribution of gamma ray bursts can, in principle, be used for studying the physical conditions of the universe before reionization epoch (which is otherwise a difficult task). (iv) It might be possible that the dark matter and dark energy arise from the same scalar field, provided the equation of state has a dependence on the length scale. The possibility of using the kinematical and geometrical measurements (such as supernova observations) for determining the nature and evolution of the dark energy is discussed.

description: We present the results of methodological works on automated analysis of the large scale distribution of galaxies. Selecting candidates for clusters and groups of galaxies was carried out using two complementary methods of determining the density contrast maps in the narrow layers of the three-dimensional large scale distribution of galaxies: the filtering algorithm with an adaptive core and the Voronoi tesselation. The developed algorithms were tested on 10 data sets of the MICE model catalog; additionally, we determined the statistical parameters of the obtained results (completeness, sample purity, etc.). The constructed density contrast maps were also used to determine voids.

description: We show that, provided one focuses on properly selected episodes, one can apply to the social sciences the same observational strategy that has proved successful in natural sciences such as astrophysics or geodynamics. For instance, in order to probe the cohesion of a policy, one can, in different countries, study the reactions to some huge and sudden exogenous shocks, which we call Dirac shocks. This approach naturally leads to the notion of structural (as opposed or complementary to temporal) forecast. Although structural predictions are by far the most common way to test theories in the natural sciences, they have been much less used in the social sciences. The Dirac shock approach opens the way to testing structural predictions in the social sciences. The examples reported here suggest that critical events are able to reveal pre-existing ``cracks'' because they probe the social cohesion which is an indicator and predictor of future evolution of the system, and in some cases foreshadows a bifurcation. We complement our empirical work with numerical simulations of the response function (``damage spreading'') to Dirac shocks in the Sznajd model of consensus build-up. We quantify the slow relaxation of the difference between perturbed and unperturbed systems, the conditions under which the consensus is modified by the shock and the large variability from one realization to another.
Minimal Length Uncertainty Relation and the Hydrogen Spectrum

description: Modifications of Heisenberg's uncertainty relations have been proposed in the literature which imply a minimum position uncertainty. We study the low energy effects of the new physics responsible for this by examining the consequent change in the quantum mechanical commutation relations involving position and momenta. In particular, the modifications to the spectrum of the hydrogen atom can be naturally interpreted as a varying (with energy) fine structure constant. From the data on the energy levels we attempt to constrain the scale of the new physics and find that it must be close to or larger than the weak scale. Experiments in the near future are expected to change this bound by at least an additional order of magnitude.

Remarks. Originally described by Doria (1888), Thominot (1899) described Salea rosaceum as a new species based on specimen MNHN-RA-0.6806 acquired from Deyrolle and believed to come from Singapore. Boulenger (1890b) recognised Thominot’s specimen as D. boulengeri, with the location as Singapore. Later, Smith (1930) recognised Thominot’s specimen as unknown because Thominot’s description did not match Salea, and because he was unable to personally examine the specimen as it was missing. However, Harvey et al. (2017) reexamined the specimen and identified it as P. tympanistriga, and determined the locality to be Java based on the specimen being shipped with specimens from two other species labelled with Java as the locality. Harvey et al. (2017) considered the possibility of the specimen being a rare endemic to Singapore, but expressed skepticism. Given their justification for the specimen arising out of Java, and that Pseudocalotes is a genus that largely occurs above 1,000 m in elevation (Grismer 2012), we also reject the possibility of P. tympanistriga being a rare Singapore endemic (see also Lim et al. 2019).

description: We study the realization of dimensional reduction and the validity of the hard thermal loop expansion for lambda phi^4 theory at finite temperature, using an environmentally friendly finite-temperature renormalization group with a fiducial temperature as flow parameter. The one-loop renormalization group allows for a consistent description of the system at low and high temperatures, and in particular of the phase transition. The main results are that dimensional reduction applies, apart from a range of temperatures around the phase transition, at high temperatures (compared to the zero temperature mass) only for sufficiently small coupling constants, while the HTL expansion is valid below (and rather far from) the phase transition, and, again, at high temperatures only in the case of sufficiently small coupling constants. We emphasize that close to the critical temperature, physics is completely dominated by thermal fluctuations that are not resummed in the hard thermal loop approach and where universal quantities are independent of the parameters of the fundamental four-dimensional theory.

description: We utilize the bulk viscosity of interacting strange quark matter to reevaluate the damping time scale. The presence of medium effect of bulk viscosity leads to a stronger damping of r-modes, which can be over an order of magnitude for realistic parameters. We find that the r-mode instability window is narrowed due to the medium effect, and hence when a pulsar reaches the instability window it will only slow down by gravitational wave emission to a period of 1.78msec instead of 2.5msec given by early estimate. As a theoretical upper rotation limit of pulsars, the period of 1.78msec is very close to the two most rapidly spinning pulsars known, with periods of about 1.6msec.

description: A galaxy's morphological features encode details about its gas content, star formation history, and feedback processes, which play important roles in regulating its growth and evolution. We use deep convolutional neural networks (CNNs) to learn a galaxy's optical morphological information in order to estimate its neutral atomic hydrogen (HI) content directly from SDSS $gri$ image cutouts. We are able to accurately predict a galaxy's logarithmic HI mass fraction, $\mathcal{M} \equiv \log(M_{\rm HI}/M_\star)$, by training a CNN on galaxies in the ALFALFA 40% sample. Using pattern recognition (PR), we remove galaxies with unreliable $\mathcal{M}$ estimates. We test CNN predictions on the ALFALFA 100%, xGASS, and NIBLES catalogs, and find that the CNN consistently outperforms previous estimators. The HI-morphology connection learned by the CNN appears to be constant in low- to intermediate-density galaxy environments, but it breaks down in the highest-density environments. We also use a visualization algorithm, Gradient-weighted Class Activation Maps (Grad-CAM), to determine which morphological features are associated with low or high gas content. These results demonstrate that CNNs are powerful tools for understanding the connections between optical morphology and other properties, as well as for probing other variables, in a quantitative and interpretable manner.

Abstract:S,S'-diphenylsulfimide, Ph2SNH, 1, is an excellent ligand that readily forms N-bound complexes with a range of transition metals. Its importance as a ligand is enhanced by two significant features of the resulting complexes: (1) the strong hydrogen bonding interactions between the NH unit and the counterions; and (2) the ligand's ability to stabilise unusual structural combinations. By varying the counterions, the hydrogen bonding pattern can be changed and this affects the geometry at the metal centre. The anion also plays an important role in determining the coordination number of the metal. The hydrogen bonding interactions have been utilised to prepare extended arrays by the inclusion of appropriate outer sphere, bridging ligands, such as terephthalate and fumarate into the system. The fixation of atmospheric CO2 has been observed in a number of systems leading to the formation of both a bicarbonate dimer and a metal-bound carbonate ligand. These act as hydrogen bonding acceptors to give extended 2-D networks. [Continues.]

description: Entangled states are an important resource for quantum computation, communication, metrology, and the simulation of many-body systems. However, noise limits the experimental preparation of such states. Classical data can be efficiently denoised by autoencoders---neural networks trained in unsupervised manner. We develop a novel quantum autoencoder that successfully denoises Greenberger-Horne-Zeilinger states subject to spin-flip errors and random unitary noise. Various emergent quantum technologies could benefit from the proposed unsupervised quantum neural networks.

description: We study the effects of a collective flow and multiple scattering on two-particle correlation measurements in Hanbury-Brown-Twiss intensity interferometry. We find that under a collective flow the effective source distribution in a two-particle correlation measurement depends on the initial source distribution. In addition, it depends on a collective flow phase function which consists of terms that tend to cancel each other. As the detected particles traverse from the source point to the freeze-out point, they are subject to multiple scattering with medium particles. We examine the effects of multiple scattering on HBT correlations. By using the Glauber theory of multiple scattering at high energies and the optical model at intermediate energies, we find that multiple scattering leads to an absorption and an effective density distribution that depends on the initial source distribution.

description: In Consumption of Food in the United States, 1909-52,1 there is presented for the first time an "index of supply-utilization" of farm products having food use. This new index breaks down the combined utilization of such products, on a farm-value basis, both according to sources of supply and according to use and disposition. The breakdown is given for each year and in terms of time series relative to the base period 1947-49. Current data of the index are now published at regular intervals in The National Food Situation.2 This article is a preliminary report by the authors of the new index. It explores some of the uses of the index, suggests further problems to which it may apply, and presents comparative trends among commodity components that were developed in its preparation. Research is continuing toward preparation of a bulletin developing these subjects and extending the index to include nonfood farm products.

description: Recent advances on the stabilization and manipulation of chiral magnetization configurations in systems consisting in alternating atomic layers of ferromagnetic and non-magnetic materials hold promise of innovation in spintronics technology. The low dimensionality of the systems promotes spin orbit driven interfacial effects like antisymmetric Dzyaloshinskii-Moriya interactions (DMI) and surface magnetic anisotropy, whose relative strengths may be tuned to achieve stable nanometer sized magnetic objects with fixed chirality. While in most of the cases this is obtained by engineering complex multilayers stacks in which interlayer dipolar fields become important, we consider here a simple epitaxial trilayer in which a ferromagnet, with variable thickness, is embedded between a heavy metal and graphene. The latter enhances the perpendicular magnetic anisotropy of the system, promotes a Rashba-type DMI, and can sustain very long spin diffusion length. We use a layer-resolved micromagnetic model (LRM) to describe the magnetization textures and their chirality. Our results demonstrate that for Co thickness larger than 3.6 nm, a skyrmion having an intrinsic mixed Bloch-Néel character with counter-clock-wise chirality is stabilized in the entire (single) Co layer. Noteworthy, for thicknesses larger than 5.4 nm, the skyrmion switches its chirality, from counter-clock-wise to clock-wise.

description: A strategic public policy decision confronting many states is whether to allow a local unit of government to file for Chapter 9 municipal bankruptcy. This is especially problematic when the pending insolvency is the result of years of structural operating deficits. Alternative strategies rely on equally undesirable public policy decisions. These range from management intervention to simply plugging the financial hole in the short‐term rather than solving long‐term imbalances. This paper will examine Chapter 9 in light of the fiscal crisis that has plagued the City of Detroit for many years. Critical to this analysis is understanding how Chapter 9 Adjustments of Debts of a Municipality works and how it is very different from the more common Chapter 11 Reorganization used in the private sector. No major decision is complete without weighing the obvious advantages with underlying long‐term consequences. Lastly, the City of Detroit does not exist in a vacuum. The outcomes of Detroit’s financial challenges have potential implications for the State of Michigan and other Michigan local units of government.
Gaussian Process Regression and Conditional Polynomial Chaos for Parameter Estimation

Year: 2019
Subjects: subject: Numerical Analysis (math.NA)

description: We present a new approach for constructing a data-driven surrogate model and using it for Bayesian parameter estimation in partial differential equation (PDE) models. We first use parameter observations and Gaussian Process regression to condition the Karhunen-Loéve (KL) expansion of the unknown space-dependent parameters and then build the conditional generalized Polynomial Chaos (gPC) surrogate model of the PDE states. Next, we estimate the unknown parameters by computing coefficients in the KL expansion minimizing the square difference between the gPC predictions and measurements of the states using the Markov Chain Monte Carlo method. Our approach addresses two major challenges in the Bayesian parameter estimation. First, it reduces dimensionality of the parameter space and replaces expensive direct solutions of PDEs with the conditional gPC surrogates. Second, the estimated parameter field exactly matches the parameter measurements. In addition, we show that the conditional gPC surrogate can be used to estimate the states variance, which, in turn, can be used to guide data acquisition. We demonstrate that our approach improves its accuracy with application to one- and two-dimensional Darcy equation with (unknown) space-dependent hydraulic conductivity. We also discuss the effect of hydraulic conductivity and head locations on the accuracy of the hydraulic conductivity estimations.

description: The Effelsberg telescope as well as the DRAO synthesis telescope are currently surveying the Galactic polarized emission at 21 cm in detail. These new surveys reveal an unexpected richness of small-scale structures in the polarized sky. However, observations made with synthesis or single-dish telescopes are not on absolute intensity scales and therefore lack information about the large-scale distribution of polarized emission to a different degree. Until now, absolutely calibrated polarization data from the Leiden/Dwingeloo polarization surveys are used to recover the missing spatial information. However, these surveys cannot meet the requirements of the recent survey projects regarding sampling and noise and new polarization observation were initiated to complement the Leiden/Dwingeloo Survey. In this paper we will outline the observation and report on the progress for a new polarization survey of the northern sky with the 26-m telescope of the DRAO.

description: Background: Self-monitoring of blood glucose (SMBG) can play a key role in diabetes management. The CONTOUR®NEXT ONE (Ascensia Diabetes Care, Parsippany, NJ, USA) blood glucose monitoring system (BGMS) has been developed for use with CONTOUR®NEXT test strips. The meter connects to the CONTOUR™ Diabetes application on a mobile device, and the Second-Chance® sampling feature recognizes insufficient sample volume, prompting the patient to apply more blood to the same strip if needed (sample re-application). Research design and methods: Two studies evaluated CONTOUR®NEXT ONE BGMS accuracy with sample re-application: a laboratory study (performance under various controlled conditions) and a clinical study (performance in the hands of 52 people with diabetes). A formal International Organization for Standardization (ISO) evaluation has been reported previously; here, accuracy criteria in the laboratory and clinical studies were aligned with ISO 15197:2013 sections 6.3.3 and 8.2, respectively. Results: All results under all conditions in the laboratory study, and with glucose concentrations <100 and ≥100 mg/dL in the clinical study, were within ±15 mg/dL or ±15% of reference measurements. In both studies, all results were within Zone A of the Parkes-Consensus Error Grid. Conclusions: These data demonstrate that the accuracy of the CONTOUR®NEXT ONE BGMS was maintained with sample re-application.

description: High costs of surveys have brought pressure for less expensive ways of getting data on family expenditures, and have raised interest in opportunities to get such data through limited supplementary schedules attached to other surveys. An experiment to test this approach was undertaken by the (former) Bureau of Agricultural Economics and the (former) Bureau of Human Nutrition and Home Economics in simultaneous surveys of farm-operator families in contiguous areas. One included a few summary questions on family spending, the other a more detailed breakdown of the major expenditure categories. This paper summarizes the comparison of data obtained from the two surveys, and discusses the implications regarding the feasibility of this approach for gathering data on family expenditures.

description: Italy (in pilot regions) and Germany (nationwide) were the first European countries to introduce universal varicella vaccination (UVV) programs. A systematic review was performed to assess varicella epidemiology before UVV programs and the impact of 1-dose and 2-dose UVV programs in Italy and Germany. Italy implemented 1- or 2-dose UVV programs successively in eight pilot regions between 2003 and 2011 and nationwide in 2017. Germany implemented 1- and 2-dose UVV programs in 2004 and 2009, respectively. While Italy had two nationwide surveillance systems in place for varicella in the pre-vaccination era, in Germany, a mandatory notification system for varicella was only introduced in the New Federal States 2 years before the 1-dose UVV implementation. Substantial reductions in moderate/severe varicella and varicella-related hospitalization incidence occurred during the 1-dose era. Further reductions were reported in Italy and Germany after the recommendation of a second dose in a long or short schedule, respectively. Different benefit-risk evaluations of a tetravalent varicella-containing vaccine (MMRV) used as a first dose led to different recommendations (MMRV versus MMR+V) in these countries. Vaccination strategies in both countries tailored to country-specific needs and goals led to a reduction in varicella-related health care hospitalization costs.

description: In \cite{ZH2019}, we developed a boundary treatment method for implicit-explicit (IMEX) Runge-Kutta (RK) methods for solving hyperbolic systems with source terms. Since IMEX RK methods include explicit ones as special cases, this boundary treatment method naturally applies to explicit methods as well. In this paper, we examine this boundary treatment method for the case of explicit RK schemes of arbitrary order applied to hyperbolic conservation laws. We show that the method not only preserves the accuracy of explicit RK schemes but also possesses good stability. This compares favourably to the inverse Lax-Wendroff method in \cite{TS2010,TWSN2012} where analysis and numerical experiments have previously verified the presence of order reduction \cite{TS2010,TWSN2012}. In addition, we demonstrate that our method performs well for strong-stability-preserving (SSP) RK schemes involving negative coefficients and downwind spatial discretizations. It is numerically shown that when boundary conditions are present and the proposed boundary treatment is used, that SSP RK schemes with negative coefficients still allow for larger time steps than schemes with all non-negative coefficients. In this regard, our boundary treatment method is an effective supplement to SSP RK schemes with/without negative coefficients for initial-boundary value problems for hyperbolic conservation laws.

description: In 1950 the Bureau of the Census changed its method of enumerating college students. In the census of that year the students were counted as residents of the localities in which they were attending college. This change makes comparisons between 1940 and 1950 census reports on population questionable, particuarly comparisons between those reflecting such factors as migration estimates and extrapolation of population changes for making current population estimates. In connection with the work of the North Central Population Dynamics Technical Committee, NC-18, a procedure for adjusting the 1940 population data to make it comparable with the 1950 data was considered necessary so that the estimates of migration into or out of a geographic area would represent the true change. This paper presents the procedure the author developed for estimating the number of students attending college from the rural and urban areas of each county in a State, based upon the census data, to be used in adjusting the 1940 data. Research work that is being initiated by the Northeast Population Dynamics Technical Committee, NE-17, will include adjustments of the 1940 census data through the use of this procedure. Helen R. White, formerly of the Farm Population and Rural Life Branch, AMS, is to be credited with ideas leading to the procedure. Many suggestions have been received from 'members of the North Central Population Dynamics Technical Committee, especially from Margaret Jarman Hagood and Paul J. Jehlik, Farm Population and Rural Life Branch, AMS, and Henry S. Shryock, Jr., Division of Population and Housing, U. S. Bureau of the Census. The paper is published with the approval of the Director of the Nebraska Agricultural Experiment Station as Journal Series Paper No. 629.

description: Glasses are ubiquitous amorphous solids that remain one of the big mysteries in condensed matter. Despite the vast body of literature on glasses, a unifying approach to link the structure and dynamics of glasses is still missing. A growing set of evidence, however, indicates the microscopic local geometry as a key ingredient. This originated from the seminal work of Frank, who conjectured that glasses may be the result of the local tendency of liquids to form icosahedral structures, which are not capable of globally filling space regularly. Here, we show that, for a fundamental glass model, dynamics can be fully understood by simply counting the number of tetrahedra. Both globally and locally, these local structures directly predict dynamical slowdown. After more than 60 years of Frank's Conjecture, it might not be the icosahedra that matter for glasses, but rather the tetrahedra inside them.
The formation of helium lines in the spectrum of COM J1740-5340

description: The He I 5876A absorption line recently discovered in the spectrum of the companion to the millisecond pulsar PSR J1740-5340 is tentatively attributed to electron impact excitations due to the irradiation of its atmosphere by gamma-rays emitted by the pulsar's magnetosphere. Numerical calculations, similar to those carried out previously for Type Ib SNe, indicate that a pulsar beam with photon energies ~ 1 MeV gives rise to a 5876A line of the observed strength if the beam's spin-down conversion efficiency approaches 1%. However, a significant difficulty for the proposed mechanism is the strength of the singlet line at 6678A. Compared to the corresponding triplets, singlet lines are weak because of the loss of excitation when photons emitted in decays to the ground state ionize hydrogen atoms, an effect absent in the hydrogen-free atmospheres of Type Ib SNe.

description: Realized net income of farm operators reached a postwar high of 16.8 billion dollars in .1947 and declined to a postwar low of 12.4 billion dollars in 1950. These estimates are for calendar years. On a quarterly basis, in terms of seasonally adjusted annual rates, the postwar high was 17.9 billion dollars in the first quarter of 1947, and the postwar low was 11.7 billion dollars in the second quarter of 1950. Thus, farmers' net income actually declined 35 percent during a period of a little more than 8 years as compared with a drop of only 26 percent indicated by the annual data. It is evident that the annual estimates do not measure the full swing from high to low. To overcome this handicap in the historical record of farm income, and to provide a foundation for more frequent and more up-to-date appraisal of the farm income situation in the future, this paper presents a new quarterly series on gross and net realized income of farm operators in terms of seasonally adjusted annual rates for 1929-53. These estimates will be published regularly henceforth in The Farm Income Situation.
