description: We present galaxy-galaxy lensing results from 139 square degrees of Dark Energy Survey (DES) Science Verification (SV) data. Our lens sample consists of red galaxies, known as redMaGiC, which are specifically selected to have a low photometric redshift error and outlier rate. The lensing measurement has a total signal-to-noise of 29 over scales $0.09 < R < 15$ Mpc/$h$, including all lenses over a wide redshift range $0.2 < z < 0.8$. Dividing the lenses into three redshift bins for this constant moving number density sample, we find no evidence for evolution in the halo mass with redshift. We obtain consistent results for the lensing measurement with two independent shear pipelines, ngmix and im3shape. We perform a number of null tests on the shear and photometric redshift catalogs and quantify resulting systematic uncertainties. Covariances from jackknife subsamples of the data are validated with a suite of 50 mock surveys. The results and systematics checks in this work provide a critical input for future cosmological and galaxy evolution studies with the DES data and redMaGiC galaxy samples. We fit a Halo Occupation Distribution (HOD) model, and demonstrate that our data constrains the mean halo mass of the lens galaxies, despite strong degeneracies between individual HOD parameters.

description: This intent paper presents an n+-p-p+ junction solar cell. The generated carriers’ density expressions has been obtained by taking account to the grain size g, the recombination velocities such as Sgb at the grains boundaries, Sb at the
back side and SF at the junction.
From the normalized carriers density plot versus the base depth, we study the space-charge layer thickness Z versus various parameters such as the grain size g, the grain boundaries recombination velocity Sgb and the wavelength l, by operating on open circuit voltage.
Hence, this allows us to establish the relation between Z and the diffusion capacitance and determine the grain size g and the grains boundaries effects on the diffusion capacitance when the solar cell is illuminated on the front side, rear side and both sides simultaneously.

description: Motivated by observations of localized electrostatic wavepackets by the Cassini and (earlier) by Voyager 1 and 2 mission(s) in Saturn's magnetosphere, we have investigated the existence conditions and the dynamical evolution of localized multi-dimensional structures in the Saturnian dusty plasma environment. To this effect, we have adopted a plasma-fluid model for dust-ion acoustic (DIA) excitations, taking into account the presence of a highly energetic (suprathermal, kappa-distributed) electron population in combination with massive dust particulates in the background. A multiple scales perturbation method was shown to lead to a Davey-Stewartson (DS) system of evolution equations, if one assumes perpendicular carrier wave propagation across the magnetic field (direction). The system is then shown to possess two regimes mainly, known in the literature as DS-I and DS-II. In the former case, if certain conditions are fulfilled, exponentially localized solutions are obtained, known as dromions. The combined effects of various physical parameters such as the electron spectral index, the ambient magnetic field (strength), and the dust concentration have been examined. A numerical investigation reveals that the dromion amplitude increases with higher dust concentration, while it decreases for lower $κ_e$ (i.e. with an increase in the suprathermal electron population component). A stronger magnetic field results in higher amplitude but narrower dromions. Our results provide a comprehensive framework for modeling modulated electrostatic wavepackets, in direct comparison with experimental data in planetary environments, in Saturn's magnetosphere, and elsewhere.

description: We investigate the structural, electronic and optical properties of mixed bromide-iodide lead perovskite solar cell CH$_3$NH$_3$Pb(I$_{1-x}$Br$_x$)$_3$ by means of the virtual crystal approximation (VCA) within density functional theory (DFT). Optimizing the atomic positions and lattice parameters increasing the bromide content $x$ from 0.0 to 1.0, we fit the calculated lattice parameter and energy band gap to the linear and quadratic function of Br content, respectively, which are in good agreement with the experiment, respecting the Vegard's law. With the calculated exciton binding energy and light absorption coefficient, we make sure that VCA gives consistent results with the experiment, and the mixed halide perovskites are suitable for generating the charge carriers by light absorption and conducting the carriers easily due to their strong photon absorption coefficient, low exciton bindign energy, and high carrier mobility at low Br contents. Furthermore analyzing the bonding lengths between Pb and X (I$_{1-x}$Br$_x$: virtual atom) as well as C and N, we stress that the stability of perovskite solar cell is definitely improved at $x$=0.2.

description: Objective To evaluate whether the expansion of Federally Qualified Health Centers (FQHCs) improved late prenatal care initiation, low birth weight, and preterm birth among Medicaid-covered or uninsured individuals. Data Sources and Study Setting We identified all FQHCs in California using the Health Resources and Services Administration's Uniform Data System from 2000 to 2019. We used data from the U.S. Census American Community Survey to describe area characteristics. We measured outcomes in California birth certificate data from 2007 to 2019. Study Design We compared areas that received their first FQHC between 2011 and 2016 to areas that received it later or that had never had an FQHC. Specifically, we used a synthetic control with a staggered adoption approach to calculate non-parametric estimates of the average treatment effects on the treated areas. The key outcome variables were the rate of Medicaid or uninsured births with late prenatal care initiation (>3 months' gestation), with low birth weight (<2500 grams), or with preterm birth (<37 weeks' gestation). Data Collection/Extraction Methods The analysis was limited to births covered by Medicaid or that were uninsured, as indicated on the birth certificate. Principal Findings The 55 areas in California that received their first FQHC in 2011–2016 were more populous; their residents were more likely to be covered by Medicaid, to be low-income, or to be Hispanic than residents of the 48 areas that did not have an FQHC by the end of the study period. We found no statistically significant impact of the first FQHC on rates of late prenatal care initiation (ATT: −10.4 [95% CI −38.1, 15.0]), low birth weight (ATT: 0.2 [95% CI −7.1, 5.4]), or preterm birth (ATT: −7.0 [95% CI −15.5, 2.3]). Conclusions Our results from California suggest that access to primary and prenatal care may not be enough to improve these outcomes. Future work should evaluate the impact of ongoing initiatives to increase access to maternal health care at FQHCs through targeted workforce investments.

description: This work deals with analyzing various types of solar cell defects. Several diagnostic methods, such as LBIC, electroluminescence or photoluminescence, are compared. The LBIC analysis is widely used as a universal method for detecting local defects in the solar cell structure. Scanning of the solar cell surface with a single point light source (laser or LED focused beam) could take several hours of processing time depending on the required picture resolution. Electroluminescence imaging (EL) and photoluminescence (PL) are much faster methods for defects detection. In EL imaging a forward bias is applied to the finished solar cells. A higher contrast between the white and the black area is attained in consequence of uneven distribution of current density. All process steps can be scanned by a CCD camera. We would like to show compare diagnostic LBIC method with electroluminescence - preferences and deficiencies, mutual comparison.

Similar splitting results are known e.g. for Lie algebroids, Dirac structures and generalized complex structures. In this paper, we develop a novel approach towards these results that leads to various generalizations, including their equivariant versions as well as their formulations in new contexts.

description: In this study, carbon nanocluster films were employed as counter electrode in dye-sensitized solar cells. The carbon nanocluster films were deposited on indium tin oxide glass using an electron cyclotron resonance chemical vapor deposition system. Results showed the microstructure and morphologies of carbon nanoclusters varied with substrate temperature. Electrochemical impedance measurement revealed that the charge-transfer resistance of a 1.3-μm-thick carbon nanocluster counter electrode in liquid electrolyte is 5.5 Ωcm2. Although this value is higher than that of thermal evaporated platinum (1.8 Ωcm2), it is superior to that of carbon film prepared from carbon particles.

description: Unlike dry granular materials, a dense granular suspension like cornstarch in water can strongly resist extensional flows. At low extension rates, such a suspension behaves like a viscous liquid, but rapid extension results in a response where stresses far exceed the predictions of lubrication hydrodynamics and capillarity. To understand this remarkable mechanical response, we experimentally measure the normal force imparted by a large bulk of the suspension on a plate moving vertically upward at a controlled velocity. We observe that above a velocity threshold, the peak force increases by orders of magnitude. Using fast ultrasound imaging we map out the local velocity profiles inside the suspension which reveal the formation of a growing jammed region under rapid extension. This region interacts with the rigid boundaries of the container through strong velocity gradients, suggesting a direct connection to the recently proposed shear-jamming mechanism.

description: We describe a building-integrated photovoltaic system in Korea. The PV modules were applied on the south wall of a new building. The evaluation and analysis range was from the PV module manufacture process to monitoring after completion of the construction. The result of monitoring showed that the generation performance of the BIPV system was changed by season. The performance ratio(PR) was about 83.6% in winter and it means that performance of this BIPV system was so good in the season. On the other hand, the PR in summer was about 75.0% dropped about 8%. It was believed that the generation performance of the BIPV system was changed by season. Because the BIPV system is constructed into the elevation of a buildng, it can gain much more irradiation in winter than in summer. And another cause is the rainy season which was inclued in the analysis period. The low irradiation condition is cause of the additional loss in the total PV sysem. When operated at low input loads the efficiency ratio of PCS drops significantly. In this study, the average conversion efficiency of PCS in summer was 76.4% decreased about 10% from 86% in winter.

description: Motivated by observations of localized electrostatic wavepackets by the Voyager 1 and 2 and Cassini missions in Saturn's magnetosphere, we have investigated the evolution of modulated electrostatic wavepackets in a dusty plasma environment. The well-known dust-ion acoustic (DIA) mode was selected to explore the dynamics of multi-dimensional structures, by means of a Davey-Stewartson (DS) model, by taking into account the presence of a highly energetic (suprathermal, kappa-distributed) electron population in combination with heavy (immobile) dust in the background. The modulational (in)stability profile of DIA wavepackets for both negative as well as positive dust charge is investigated. A set of explicit criteria for modulational instability (MI) to occur is obtained. Wavepacket modulation properties in 3D dusty plasmas are shown to differ from e.g. Maxwellian plasmas in 1D. Stronger negative dust concentration results in a narrower instability window in the $K$ (perturbation wavenumber) domain and a suppressed growth rate. In the opposite manner, the instability growth rate increases for higher positive dust concentrations and the instability window gets larger. In a nutshell, negative dust seems to suppress instability while positive dust appears to favor the amplitude modulation instability mechanism.

description: Mobility interventions in communities play a critical role in containing a pandemic at an early stage. The real-world practice of social distancing can enlighten policymakers and help them implement more efficient and effective control measures. A lack of such research using real-world observations initiates this article. We analyzed the social distancing performance of 66,149 census tracts from 3,142 counties in the United States with a specific focus on income profile. Six daily mobility metrics, including a social distancing index, stay-at-home percentage, miles traveled per person, trip rate, work trip rate, and non-work trip rate, were produced for each census tract using the location data from over 100 million anonymous devices on a monthly basis. Each mobility metric was further tabulated by three perspectives of social distancing performance: “best performance,” “effort,” and “consistency.” We found that for all 18 indicators, high-income communities demonstrated better social distancing performance. Such disparities between communities of different income levels are presented in detail in this article. The comparisons across scenarios also raise other concerns for low-income communities, such as employment status, working conditions, and accessibility to basic needs. This article lays out a series of facts extracted from real-world data and offers compelling perspectives for future discussions.

description: In contrast to bulk FeSe, which exhibits nematic order and low temperature superconductivity, atomic layers of FeSe reverse the situation, having high temperature superconductivity appearing alongside a suppression of nematic order. To investigate this phenomenon, we study a minimal electronic model of FeSe, with interactions that enhance nematic fluctuations. This model is sign problem free, and is simulated using determinant quantum Monte Carlo (DQMC). We developed a DQMC algorithm with parallel tempering, which proves to be an efficient source of global updates and allows us to access the region of strong interactions. Over a wide range of intermediate couplings, we observe superconductivity with an extended s-wave order parameter, along with enhanced, but short ranged, $q=(0,0)$ ferro-orbital (nematic) order. These results are consistent with approximate weak coupling treatments that predict that nematic fluctuations lead to superconducting pairing. Surprisingly, in the parameter range under study, we do not observe nematic long range order. Instead, at stronger coupling an unusual insulating phase with $q=(π,π)$ antiferro-orbital order appears, which is missed by weak coupling approximations.

description: Resonant energy transfer, energy transfer upconversion, and energy pooling are considered within optical cavities to elucidate the relationship between exciton dynamics and donor/acceptor separation distance. This is accomplished using perturbation theory to derive analytic expressions for the electric dipole coupling tensors of perfect planar and rectangular channel reflectors---directly related to a number of important energy transfer processes. In the near field, the separation dependence along the cavity axis is not influenced by the cavity and is essentially the same as for three-dimensional, free space. This is in sharp contrast to the reduced sensitivity to separation found in idealized low-dimensional settings. The cavity dynamics only correspond to their reduced dimensional counterparts in the far field where such excitonic processes are not typically of interest. There is an intermediate regime, though, where sufficiently small cavities cause a substantial decrease in separation sensitivity that results in one component of the dipole-dipole coupling tensor being much larger than those of free space.

description: Luminescent solar concentrators are planar concentrators based on trapping light and wave-guiding it to attached PV cells. They are well suited for building integration, viable in locations with significant indirect sunlight and can be complementary to geometric high-concentration systems. Nanorods have been proposed as novel luminescent centres with promising properties, such as reduced self-absorption. Several nanorod doped concentrators have been fabricated and characterised in order to investigate the dependence of LSC performance on size and dopant concentration. The experimental results illustrate the effect of re-absorption and the associated losses with increasing size and concentration. Computational results using a raytrace model are in good agreement with the experiments. Furthermore, the raytrace model was employed to make realistic projections and extend the parameter range of the experiment.

Tahan, 04.38N, 102.14E (BirdLife International, 2001: 2632), 4000 ft, Malaysia, in September 1901, by John Waterstradt. From the Rothschild Collection. COMMENTS: Hartert did not designate a type in the original description, saying only that his series consisted of two adult specimens, both marked male, collected in September and October 1901. Later, Hartert (1920a: 440) listed the adult male collected in September as the type, thereby designating it the lectotype. The paralectotype is AMNH 684087, male, collected on Mt. Tahan in October 1901. Dickinson (2006: 234) and Dickinson et al. (2006b: 292) considered saturatior a synonym of S. frontalis frontalis, with the caveat that Wells (then in press) considered birds of the Malay Peninsula distinct. Wells (2007: 430) discussed the two subspecies and recognized saturatior; Harrap (2008b: 142–143) also recognized saturatior for Malay Peninsula birds.

description: There is robust evidence that gendered racial microaggressions affect Black women's mental health. However, few studies have examined how this form of discrimination affects Black women's social anxiety in addition to their general anxiety, as well as the underlying mechanisms related to gendered racial microaggressions and anxiety. Objective The purpose of this study was to examine the associations between gendered racial microaggressions stress (GRMS) and gendered racial microaggressions frequency (GRMF), and Black women's social anxiety and general anxiety symptoms. We also examined the mediating roles of distress intolerance and stress in these associations. Method One hundred and sixty-three Black women, between the ages of 18 and 25 years old, completed a cross-sectional survey. Regression analyses were used to examine the associations between gendered racial microaggressions and social anxiety and general anxiety, and mediation analyses examined the indirect effect of gendered racial microaggressions on the outcome variables through distress intolerance and stress. Results GRMS was associated with greater social and general anxiety through the mechanisms of distress intolerance and stress. GRMF was associated with reduced social anxiety and was not associated with general anxiety. Conclusions Intervention efforts should be aimed to prevent the experience of gendered racial microaggressions to prevent subsequent stress and mental health outcomes for Black women.

description: For the purpose of elucidating the gas sensing mechanism of SnO$_2$ for NO and NO$_2$ gases, we calculate the phase diagram of SnO$_2$(110) surface in contact with an O$_2$ and NO gas environment by means of {\it ab initio} thermodynamic method. Firstly we build a range of surface slab models of oxygen pre-adsorbed SnO$_2$(110) surfaces using (1$\times$1) and (2$\times$1) surface unit cells and calculate their Gibbs free energies considering only oxygen chemical potential. The fully reduced surface containing the bridging and in-plane oxygen vacancies in the oxygen-poor condition, while the fully oxidized surface containing the bridging oxygen and oxygen dimer in the oxygen-rich condition, and the stoichiometric surface in between, were proved to be most stable. Using the selected plausible NO-adsorbed surfaces, we then determine the surface phase diagram of SnO$_2$(110) surfaces in ($Δμ_\text{O}$, $Δμ_\text{NO}$) space. In the NO-rich condition, the most stable surfaces were those formed by NO adsorption on the most stable surfaces in contact with only oxygen gas. Through the analysis of electronic charge transferring and density of states during NO$_x$ adsorption on the surface, we provide a meaningful understanding about the gas sensing mechanism.

description: Indirect reciprocity is a major mechanism in the maintenance of cooperation among unrelated individuals. Indirect reciprocity leads to conditional cooperation according to social norms that discriminate the good (those who deserve to be rewarded with help) and the bad (those who should be punished by refusal of help). Despite intensive research, however, there is no definitive consensus on what social norms best promote cooperation through indirect reciprocity, and it remains unclear even how those who refuse to help the bad should be assessed. Here, we propose a new simple norm called "Staying" that prescribes abstaining from assessment. Under the Staying norm, the image of the person who makes the decision to give help stays the same as in the last assessment if the person on the receiving end has a bad image. In this case, the choice about whether or not to give help to the potential receiver does not affect the image of the potential giver. We analyze the Staying norm in terms of evolutionary game theory and demonstrate that Staying is most effective in establishing cooperation compared to the prevailing social norms, which rely on constant monitoring and unconditional assessment. The application of Staying suggests that the strict application of moral judgment is limited.

description: The performance of dye-sensitized solar cells, based on pure 1-propyl-3-methyl-imidazolium iodide ionic liquid electrolyte with different iodine concentrations has been evaluated under different light intensities (10-100 mW/cm2) and for different cell temperatures (5-55 ºC). At lower cell temperatures a short-circuit current (JSC) may be limited by the diffusion of tri-iodide therefore the JSC increases with increasing temperature, until it reaches a maximum. Further increase in temperature leads to a decreases of the JSC due to more pronounced recombinations. The maximum of JSC shifts to lower cell temperatures by increasing iodine concentration or decreasing light intensity. The open circuit voltage decreases linearly with increasing temperature or quasi proportionally to iodine concentration and increases logarithmically with increasing the light intensity, while the conversion efficiency follows the temperature dependence of JSC.

description: Dendrophila corallipes Sharpe Dendrophila corallipes Sharpe, 1888b: 479 (Mountain of Kina Balu). Now Sitta frontalis corallipes (Sharpe, 1888). See Dickinson et al., 2006b: 293, and Harrap, 2008b: 142–143. HOLOTYPE: AMNH 684092, adult female, collected on Mt. Kinabalu, 3000 ft, 06.03N, 116.32E (Times Atlas), Sabah, Malaysia, on 26 February 1887, by John Whitehead (no. 1030). From the Rothschild Collection. COMMENTS: No type was designated in the description of this form nor was the number of specimens listed, but Sharpe (1888b: 478) had before him Whitehead’s entire 1887 collection made during his second ascent of Kinabalu and based his descriptions on those specimens. In his later account of Whitehead’s four years of travels in northern Borneo (Sharpe, 1889), he again did not name a type for corallipes, but listed a total of five specimens, only one of which was collected in 1887. The data on AMNH 684092 match the data listed by Sharpe (1889: 420) as his specimen ‘‘d,’’ and the reverse of Whitehead’s label is marked ‘‘ Type RBS,’’ indicating that it was the specimen chosen, but not published, by Sharpe as the type. Hartert (1920a: 440) listed this specimen as the type, adding Whitehead’s no. 1030.

description: The installation of PV modules on horizontal roofs of buildings permits their natural cooling as front and rear PV module surfaces have thermal losses to the ambient by convection and radiation. In the facades and inclined roofs, the cooling of PV rear surface has a positive result in PV electrical efficiency and besides it contributes to the building protection from overheating during summer. Air-cooled hybrid Photovoltaic/Thermal (PV/T) systems have been recently applied on building inclined roofs or façades aiming to cover building space heating needs during winter and ventilation cooling demand during summer. In air-cooled hybrid PV/T systems an air channel is usually mounted at PV module rear side and air of lower temperature than that of PV modules, usually ambient air, is circulating in the channel to achieve PV cooling and keep the PV electrical efficiency at a sufficient level. In the present work, an experimental device of three meters in length is studied, consisting of air-cooled commercial pc-Si PV modules placed in a series and operating with natural air flow. Two low cost modification techniques to enhance heat transfer to air stream in the air channel are studied and compared with system operation by using air channel of typical form. The considered modifications consist of thin metal sheet suspended at the middle of air channel or fins attached to the back wall of it, to improve heat extraction from PV module. The modified systems present increased electrical and thermal output, compared to the usual type and can contribute to performance improvement of the integrated PV systems for the natural ventilation applications in buildings, mounted on the façade and inclined roof of them.
QFT in Curved Spacetime from Quantum Gravity: proper WKB decomposition of the gravitational component

description: Starting from a re-analysis of previous work, we construct the proper low energy quantum field theory (QFT) limit of a full quantum gravity theory in the Born-Oppenheimer approach. We separate the gravitational sector into a classical background, given by a vacuum diagonal Bianchi I cosmology, and its quantum perturbations represented by the two graviton degrees of freedom; we further include quantum matter in the form of a test scalar field. We then implement a Born-Oppenheimer separation, where the gravitons and matter play the role of "slow" and "fast" quantum components respectively, and perform a Wentzel-Kramers-Brillouin (WKB) expansion in a Planckian parameter. The functional Schrödinger evolution for matter is recovered after averaging over quantum gravitational effects, provided that a condition is imposed on the gravitons' wave functional. Such a condition fixes the graviton dynamics and is equivalent to the purely gravitational Wheeler-DeWitt constraint imposed in previous approaches. The main accomplishment of the present work is to clarify that QFT in curved spacetime can be recovered in the low energy limit of quantum gravity only after averaging over the graviton degrees of freedom, in the spirit of effective field theory. Furthermore, it justifies a posteriori the implementation of the gravitational Wheeler-DeWitt equation on the "slow" gravitons' wave functional rather than assuming its validity a priori.
