description: An increased use of models for measuring response styles is apparent in recent years with the multidimensional nominal response model (MNRM) as one prominent example. Inclusion of latent constructs representing extreme (ERS) or midpoint response style (MRS) often improves model fit according to information criteria. However, a test of absolute model fit is often not reported even though it could comprise an important piece of validity evidence. Limited information test statistics are candidates for this task, including the full (M2), ordinal (M2*), and mixed (C2) statistics, which differ in whether additional collapsing of univariate or bivariate contingency tables is conducted. Such collapsing makes sense when item categories are ordinal, which may not hold under the MNRM. More generally, limited information test statistics have gone unevaluated under nominal data and non-ordinal latent trait models. We present a simulation study evaluating the performance of M2, M2*, and C2 with the MNRM. Manipulated conditions included sample size, presence and type of response style, and strength of item slopes on substantive and style dimensions. We found that M2 sometimes had inflated Type I error rates, M2* always had little power, and C2 lacked power under some conditions. M2 and C2 may provide complementary and valuable information regarding model fit.
The Deterrent Effects of Police Patrol Presence On Criminal and Disorderly Behavior at High Crime Locations
Creators: name: Koper, Christopher Sean
Publisher: name: Digital Repository at the University of Maryland
Year: 1992

description: This paper tests the deterrent ( or displacement) effects of preventive patrol upon criminal and non-criminal disorderly behaviors at high-crime locations ("hot spots") using observational data collected during a preventive patrol experiment in Minneapolis from December 1988 to November 1989. The analyses reveal that the immediate presence of uniformed police directly reduces the outbreak of disorderly conduct at hot spots, but this effect is contingent upon raising the overall level of proactive presences at hot spots. Increasing patrol levels at hot spots also produces residual deterrence which decreases disorder during times when police are not present at these locations. Such residual decreases in disorder are larger than the direct deterrent effects of police presence when patrol is at normal levels. Further, direct and residual deterrence generated by patrol are stronger for criminal acts than for a combined measure of criminal and non-criminal disorderly behaviors. The analyses employed survival models to estimate the effects of specific instances of patrol presence upon the time to the first disorder (criminal or non-criminal) after police depart from a hot spot. Using presences up to 20 minutes in length, these models reveal that longer presences increase survival time, thus enhancing residual deterrence. However, there is evidence this effect decreases after presences pass about 14 minutes in duration. Moreover, stops must be about 10 minutes in length in order to produce significantly better survival times than those produced by driving through a hot spot. The theoretical and policy implications of these results are discussed.

description: Counterfactual thinking (CFT), or simulating alternative versions of occurred events, is a common psychological strategy people use to process events in their lives. However, CFT is also a core component of ruminative thinking that contributes to psychopathology. Though prior studies have tried to distinguish adaptive from maladaptive CFT, our study provides a novel demonstration that identifies phenomenological differences across CFT in participants with varying levels of trait anxiety. Participants (N = 96) identified negative, regretful memories from the past 5 years and created a better counterfactual alternative (upward CFT), a worse counterfactual alternative (downward CFT), or simply recalled each memory. Participants with high levels of trait anxiety used more negative language when describing their mental simulations, reported lower ratings of composition during upward CFT, and reported more difficulty in imagining the emotion they would have felt had negative events turned out to be better. Additionally, participants with high anxiety thought that upward CFT was less likely to occur relative to individuals with low anxiety. These results help to clarify how mental simulations of aversive life events are altered in anxiety and serve as a stepping stone to future research uncovering the mechanisms of ruminative thought patterns.
Evaporation residue cross-sections as a probe for nuclear dissipation in the fission channel of a hot rotating nucleus

Subjects: subject: Nuclear Theory (nucl-th)

description: Evaporation residue cross-sections are calculated in a dynamical description of nuclear fission in the framework of the Langevin equation coupled with statistical evporation of light particles. A theoretical model of one-body nuclear friction which was developed earlier, namely the chaos-weighted wall formula, is used in this calculation for the 224Th nucleus. The evaporation residue cross-section is found to be very sensitive to the choice of nuclear friction. The present results indicate that the chaotic nature of the single-particle dynamics within the nuclear volume may provide an explanation for the strong shape-dependence of nuclear friction which is usually required to fit experimental data.

Conjugate heat transfer in the unbounded flow of a viscoelastic fluid past a sphere

description: This work addresses the conjugate heat transfer of a simplified PTT fluid flowing past an unbounded sphere in the Stokes regime ($Re = 0.01$). The problem is numerically solved with the finite-volume method assuming axial symmetry, absence of natural convection and constant physical properties. The sphere generates heat at a constant and uniform rate, and the analysis is conducted for a range of Deborah ($0 \leq De \leq 100$), Prandtl ($10^0 \leq Pr \leq 10^5$), Brinkman ($0 \leq Br \leq 100$) and conductivity ratios ($0.1 \leq κ\leq 10$), in the presence or absence of thermal contact resistance at the solid-fluid interface. The drag coefficient shows a monotonic decrease with $De$, whereas the stresses on the sphere surface and in the wake first increase and then decrease with $De$. A negative wake was observed for the two solvent viscosity ratios tested ($β$ = 0.1 and 0.5), being more intense for the more elastic fluid. In the absence of viscous dissipation, the average Nusselt number starts to decrease with $De$ after an initial increase. Heat transfer enhancement relative to an equivalent Newtonian fluid was observed for the whole range of conditions tested. The temperature of the sphere decreases and becomes more homogeneous when its thermal conductivity increases in relation to the conductivity of the fluid, although small changes are observed in the Nusselt number. The thermal contact resistance at the interface increases the average temperature of the sphere, without affecting significantly the shape of the temperature profiles inside the sphere. When viscous dissipation is considered, significant changes are observed in the heat transfer process as $Br$ increases. Overall, a simplified PTT fluid can enhance heat transfer compared to a Newtonian fluid, but increasing $De$ does not necessarily improve heat exchange.

description: We argue that a width of less than MeV of the new Theta resonance is inconsistent with the observed ratio of resonance and background events in the various photon initiated experiments if the latter can be described by K, K*, etc., exchange. An evaluation of the Feynman diagrams which were believed to be relevant is presented and supports the general claim in the one case where a cross section has been given by the experimental group. More detailed arguments based on the flux tube model explaining the narrow widths and the apparent conflict with the production rates are presented. We predict narrow Tetra-quarks at mass ~ O(1-1.2 GeV) which the analysis of LEAR may have missed.

Search for Antimatter with the AMS Cosmic Ray Detector

Publisher: name: arXiv
Year: 2003
Subjects: subject: Astrophysics (astro-ph)

description: Antimatter search results of the Alpha Magnetic Spectrometer (AMS) detector are presented. About 100 million triggers were collected in the 1998 precursor flight onboard space shuttle Discovery. This ten day mission exposed the detector on a 51.7 degrees orbit at an altitude around 350 km. Identification of charged cosmic rays is achieved by multiple energy loss and time-of-flight measurements. Bending inside the 0.15 T magnetic volume yields a measurement of the absolute value of the particle's rigidity. The supplemental knowledge of the sense of traversal identifies the sign of the charge. In the rigidity range 1 < R < 140 GV no antinucleus at any rigidity was detected, while 2.86 million helium and 165 thousand heavy nuclei were precisely measured. Hence, upper limits on the flux ratio antinuclei-to-nuclei are given. Different prior assumptions on the antimatter spectrum are considered and corresponding limits are given.

description: Several recent studies have shown that the Vela OB2 region hosts a complex constellation of sub-populations with ages in the range 10 to 50 Myr. Such populations might represent the best example of the outcome of clustered star formation in Giant Molecular clouds (GMC). We use Gaia DR2 data over an area of 40 deg radius around the open cluster Collinder 135 to extend the study of the stellar populations of the Vela OB2 region over an area of several hundreds of parsecs on sky. Detailed clustering algorithms combined with the exquisite astrometric quality of the GAIA catalogue allow us to detect a new cluster named BBJ 1 that shows the same age as NGC 2547 (30 to 35 Myr), but located at a distance of 260 pc from it. Deeper investigation of the region via clustering in 5D parameter space and in the colour-magnitude diagram allows us to detect a filamentary structure of stars that bridges the two clusters. Given the extent in space of such structure (260 pc) and the young age (~35 Myr), we exclude that such population originates by the same mechanism responsible to create tidal streams around older clusters. Even if we miss a complete picture of the 3D motion of the studied stellar structure because of the lack of accurate radial velocity measurements, we propose that such structure represent the detection of a 35 Myr old outcome of a mechanism of filamentary star formation in a GMC.

The object -- named UYSO 1 (Unidentified Young Stellar Object 1) -- is cold (T=40 K), it has a massive envelope, and it is associated with an energetic molecular outflow. No infrared point source has been detected at its position for wavelengths below 20 micron. Therefore, it is a very good candidate for a member of the long searched for group of massive protostars.

Secular evolution of close in planets: the effects of general relativity

Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)

description: Pairs of planets in a system may end up close to their host star on eccentric orbits as a consequence of planet planet scattering, Kozai or secular migration. In this scenario, general relativity and secular perturbations have comparable timescales and may interfere with each other with relevant effects on the eccentricity and pericenter evolution of the two planets. We explore, both analytically and via numerical integration, how the secular evolution is changed by general relativity for a wide range of different initial conditions. We find that when the faster secular frequency approaches the general relativity precession rate, which tipically occurs when the outer planet moves away from the inner one, it relaxes to it and a significant damping of the proper eccentricity of the inner planet occurs. The proper eccentricity of the outer planet is reduced as well due to the changes in the secular interaction of the bodies. The lowering of the peak eccentricities of the two planets during their secular evolution has important implications on their stability. A significant number of two planet systems, otherwise chaotic because of the mutual secular perturbations, are found stable when general relativity is included.

description: Convolutional neural networks (CNNs) have recently demonstrated superior quality for computational imaging applications. Therefore, they have great potential to revolutionize the image pipelines on cameras and displays. However, it is difficult for conventional CNN accelerators to support ultra-high-resolution videos at the edge due to their considerable DRAM bandwidth and power consumption. Therefore, finding a further memory- and computation-efficient microarchitecture is crucial to speed up this coming revolution. In this paper, we approach this goal by considering the inference flow, network model, instruction set, and processor design jointly to optimize hardware performance and image quality. We apply a block-based inference flow which can eliminate all the DRAM bandwidth for feature maps and accordingly propose a hardware-oriented network model, ERNet, to optimize image quality based on hardware constraints. Then we devise a coarse-grained instruction set architecture, FBISA, to support power-hungry convolution by massive parallelism. Finally,we implement an embedded processor---eCNN---which accommodates to ERNet and FBISA with a flexible processing architecture. Layout results show that it can support high-quality ERNets for super-resolution and denoising at up to 4K Ultra-HD 30 fps while using only DDR-400 and consuming 6.94W on average. By comparison, the state-of-the-art Diffy uses dual-channel DDR3-2133 and consumes 54.3W to support lower-quality VDSR at Full HD 30 fps. Lastly, we will also present application examples of high-performance style transfer and object recognition to demonstrate the flexibility of eCNN.

description: We report accurate redshifts of 110 active galaxies (mostly radio-loud objects at z<0.4) observed in the course of a survey to find broad, double-peaked emission lines. These redshifts are measured from the narrow emission lines of these objects and are accurate to at least one part in 10^4 . For each object we determine a redshift from high- and low-ionization lines separately, as well as an average redshift from all the available lines. We find that in about 15% of cases, the low-ionization lines yield a slightly higher redshift than the high-ionization lines; the average redshift difference amounts to a velocity difference of approximately 80 km/s. In addition to the redshift measurements we also report revised redshifts for two objects as well as new classifications for three narrow-line objects.

description: Motivated by the presence of various charge inhomogeneities in strongly correlated systems of coupled ladders, a model of spatially separated bosonic and fermionic degrees of freedom is numerically studied. In this model, bosonic chains are connected to fermionic chains by two types of generalized Andreev couplings. It is shown that for both types of couplings the long-distance pairing correlations are enhanced. Near quarter filling, this effect is much larger for the splitting of a pair in electrons which go to the two neighboring fermionic chains than for a pair hopping process. It is argued that the pairing enhancement is a result of the nearest neighbor Coulomb repulsion which tunes the competition between pairing and charge ordering.

description: Although people often use multiple strategies to regulate their emotions, it is unclear if using more strategies effectively changes emotional outcomes. This may be because there is no clear, data-driven structure to organise which strategies people use together, so strategies with opposing impacts are modelled together. We first conducted a multilevel factor analysis of negative- and positive-emotion regulation strategies among undergraduates (n = 92) completing ecological momentary assessment three times per day for 10 days. Solutions including 3-within/3-between factors were most interpretable. Using more between-person Adaptive Engagement strategies and within-person Adaptive Engagement, Enhancement, and Behavioural strategies predicted improved mood, whereas using more between-person Aversive Cognitive and within-person Aversive Cognitive and Disengagement strategies predicted worse mood, ps < .05. Using a greater quantity of strategies may thus promote better, or worse, emotional outcomes, depending on the class of strategies used.
Galactic Magnetic Field Bias on Inferences from UHECR Data

description: A consequence of Liouville's theorem indicates that the recently observed large scale anisotropy in the arrival direction of Ultra-High-Energy Cosmic Rays (UHECRs) cannot be produced by the Galactic magnetic field, thus this anisotropy already needs to be present outside our Galaxy. But in this case, the observed energy spectrum and composition of UHECRs differs from the one outside of the Milky Way, due to the suppression or the amplification of the UHECR flux from certain directions by the Galactic magnetic field. In this work, we investigate this effect for the case of a dipole and a quadrupole anisotropy, respectively, for the widely-used JF12 magnetic field model. We investigate boundaries on the maximal amplitude of the observed anisotropy and the maximal charge number of UHECRs. Furthermore, the flux modification is discussed in the light of the Auger data on the recent dipole and also the chemical composition. We find that this modification effect yields a modification of the observed flux of up to $\sim 10\%$ for the investigated magnetic field model and the observed dipole, in particular for a heavy chemical composition of UHECRs as suggested by the 'EPOS-LHC' model.

description: We have investigated the physical and chemical status of the pre-protostellar core B68. A previous extinction study suggested that the density profile of B68 is remarkably consistent with a Bonnor-Ebert sphere with 2.1 $M_{\odot}$ at 16 K. We mapped B68 in C3H2, CCS, and NH3 with the Deep Space Network (DSN) 70m telescope at Goldstone. Our results show that the B68 chemical structure is consistent with that seen in other pre-protostellar cores (L1498, L1544) and is explained by time dependent chemical models that include depletion. We measured a kinetic temperature of 11K with NH3 (1,1) and (2,2) spectra. We also show that B68 is thermally dominated with little contribution from turbulence support (< 10%). We consider a modified Bonnor-Ebert sphere to include effects of turbulence and magnetic fields and use it to constrain the uncertainties in its distance determination. We conclude that the distance to B68 is $\sim$ 95pc with a corresponding mass of $\sim$ 1.0 $M_{\odot}$. If some magnetic field is present it can be further away (beyond $\sim$ 100pc) and still satisfy the density structure of a Bonnor-Ebert sphere. Our observations do not preclude any instability such as the onset of collapse, or slow contraction, occurring in the center of the core, which cannot be resolved with our beam size (45").

description: In this note the Choquet type operators are introduced, in connection to Choquet's theory of integrability with respect to a not necessarily additive set function. Based on their properties, a quantitative estimate for the nonlinear Korovkin type approximation theorem associated to Bernstein-Kantorovich-Choquet operators is proved. The paper also includes a large generalization of Hölder's inequality within the framework of monotone and sublinear operators acting on spaces of continuous functions.

description: We present a high-resolution spectroscopic study of the envelope of the young Class 0 protostar IRAM 04191+1522 in Taurus. N2H+(1-0) observations with the Plateau de Bure Interferometer and the IRAM 30m telescope demonstrate that the molecular ion N2H+ disappears from the gas phase in the inner envelope (r < 1600 AU, n(H2) > 4-7 * 1e5 cm-3). This may result from N2 depletion on polar ice mantles and enhanced grain chemistry.

description: As several photovoltaic materials experimentally approach the Shockley-Queisser limit, there has been a growing interest in unconventional materials and approaches with the potential to cross this efficiency barrier. One such candidate is dark state protection induced by the dipole-dipole interaction between molecular excited states. This phenomenon has been shown to significantly reduce carrier recombination rate and enhance photon-to-current conversion, in elementary models consisting of few interacting chromophore centers. Atomically thin 2D transition metal di-chalcogenides (TMDCs) have shown great potential for use as ultra-thin photovoltaic materials in solar cells due to their favorable photon absorption and electronic transport properties. TMDC alloys exhibit tunable direct bandgaps and significant dipole moments. In this work, we introduce the dark state protection mechanism to a TMDC based photovoltaic system with pure tungsten diselenide (WSe2) as the acceptor material and the TMDC alloy tungsten sulfo-selenide (WSeS) as the donor material. Our numerical model demonstrates the first application of the dark state protection mechanism to a photovoltaic material with a photon current enhancement of up to 35% and an ideal photon-to-current efficiency exceeding the Shockley-Queisser limit.

description: Today's datacenter applications are underpinned by datastores that are responsible for providing availability, consistency, and performance. For high availability in the presence of failures, these datastores replicate data across several nodes. This is accomplished with the help of a reliable replication protocol that is responsible for maintaining the replicas strongly-consistent even when faults occur. Strong consistency is preferred to weaker consistency models that cannot guarantee an intuitive behavior for the clients. Furthermore, to accommodate high demand at real-time latencies, datastores must deliver high throughput and low latency. This work introduces Hermes, a broadcast-based reliable replication protocol for in-memory datastores that provides both high throughput and low latency by enabling local reads and fully-concurrent fast writes at all replicas. Hermes couples logical timestamps with cache-coherence-inspired invalidations to guarantee linearizability, avoid write serialization at a centralized ordering point, resolve write conflicts locally at each replica (hence ensuring that writes never abort) and provide fault-tolerance via replayable writes. Our implementation of Hermes over an RDMA-enabled reliable datastore with five replicas shows that Hermes consistently achieves higher throughput than state-of-the-art RDMA-based reliable protocols (ZAB and CRAQ) across all write ratios while also significantly reducing tail latency. At 5% writes, the tail latency of Hermes is 3.6X lower than that of CRAQ and ZAB.

description: La transición a la energía limpia tendrá implicaciones particularmente significativas para las personas, donde los Recursos Naturales como el carbón, el petróleo y el gas natural son los principales impulsores de su economía; y donde los consumidores pueden verse especialmente afectados por los cambios en el sistema energético. Políticas de subvención mal aplicadas, podrían generar impactos sociales significativos en la lucha contra la pobreza y desigualdad fiscal de quienes lo aplican. Este trabajo presenta una variedad de propuestas para ayudar a permitir una transición energética equitativa. No pretendemos entregar una estrategia integral, sino ofrecer un menú de opciones que permitan a los responsables de la formulación de políticas públicas, pueden elegir un camino que les permita realizar una transición exitosa, al tiempo de mejorar la equidad energética y la resiliencia actual que vivimos. La reducción de potenciales daños ambientales, estimulará la innovación en energías limpias, apoyado por el desarrollo económico en especial a la fuerza laboral de aquellas comunidades vulnerables.

description: In this study, structural stability, electronic, optical and vibrational properties of DNA nucleobase adsorbed Graphene Quantum Dot (GQD) has been investigated using density functional theory. Based on state-of-art electronic structure calculations, we predict order of GQD sensitivity for DNA nucleobase as Thymine > Cytosine > Guanine > Adenine. An interaction of GQD with DNA nucleobase leads to modulation in electronic energy gap. Our calculated UV/vis and IR vibrational spectra show unique spectral band that can be used fingerprints in next generation DNA sequencing diagnostics.

description: Large-scale QRPA calculations of the E1 strength are performed on top of HFB calculations in order to derive the radiative neutron capture cross sections for the whole nuclear chart. The spreading width of the GDR is taken into account by analogy with the second-RPA (SRPA) method. The accuracy of HFB+QRPA model based on various Skyrme forces with different pairing prescription and parameterization is analyzed. It is shown that the present model allows to constrain the effective nucleon-nucleon interaction with the GDR data and to provide quantitative predictions of dipole strengths.

description: Highly non-ideal solutions are ever-present within chemistry, physics, and materials science â and are characterized by many-body effects across length and timescale. Understanding, and predicting, many-body correlations in the condensed phase is a grand challenge for the modeling and simulation community. Yet within the data science community, a large suite of tools exist for elucidating complex, correlating, relationships amongst variables. Molecular modeling and simulation data is in fact well-suited for study by methods that include the topology of graphs, point cloud data, and recent advances in applied mathematics methods that investigate surfaces like sublevel set persistent homology and geometric measure theory. We adapt, develop, and apply these tools to study highly non-ideal solutions and their interfaces, with examples drawn from separations science. The new physical insight derived from these methods is paving the way for bespoke liquid/liquid interfaces that optimize transport characteristics for purification and synthesis.
Compact lattice U(1) and Seiberg-Witten duality: a quantitative comparison

description: It was conjectured some time ago that an effective description of the Coulomb-confinement transition in compact U(1) lattice gauge field theory could be described by scalar QED obtained by soft breaking of the N=2 Seiberg-Witten model down to N=0 in the strong coupling region where monopoles are light. In two previous works this idea was presented at a qualitative level. In this work we analyze in detail the conjecture and obtain encouraging quantitative agreement with the numerical determination of the monopole mass and the dual photon mass in the vicinity of the Coulomb to confining phase transition.
