description: Blazars with redshifts z<0.1 are likely candidates for detection at energies in the range 300 GeV - 50 TeV with Cerenkov telescopes and scintillator arrays. We present gamma-ray flux predictions for a sample of 15 nearby flat-spectrum radio sources fitting the proton blazar model of Mannheim (1993a) to their observed broad-band spectral energy distributions. At high energies, we use fluxes or flux limits measured by ROSAT, CGRO and the Whipple Observatory to constrain their spectra. We take into account absorption of the gamma-rays by pair production with low energy photons of the diffuse infrared-to-optical photon background produced by galaxies (cosmic absorption) and with low energy synchrotron photons of the blazar radiation field (internal absorption). Typically, the theoretical spectra decrease much faster above TeV (photon index s~3) than between GeV and TeV (s~2) owing to internal absorption. The predicted fluxes are confronted with flux limits in the 20-50 TeV energy range obtained by the High Energy Gamma Ray Astronomy (HEGRA) experiment. Without cosmic absorption, the fluxes are about equal to the current sensitivity of HEGRA. Improved gamma/hadron separation techniques could render a detection by HEGRA possible, if cosmic absorption by the far-infrared background at wavelengths ~100 mu is not exceedingly strong.

description: We study the pair production of charginos in e+e- collisions followed by the decay via R-parity violating LQD operators. We determine the complete matrix element squared for chargino decays via LQD or LLE operators. We find regions in MSSM parameter space where the chargino mass is 52.5GeV and the R-parity violating decays of the charginos dominate the gauge decays to neutralinos. At LEP2 this then leads to additional 4 jet events which could explain the excess recently observed by ALEPH.

The Gamma Ray Burst Rate at High Photon Energies
Creators: name: Mannheim, Karl

Publisher: name: arXiv
Year: 1996
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Some gamma-ray burst (GRB) spectra exhibit high energy tails with the highest photon energy detected at 18 GeV. The spectral slope of the high-energy tails is sufficiently flat in nu F_nu to consider the possibility of their detection at still higher energies. We calculate how many bursts can reasonably be expected above a given energy threshold for a cosmological distribution of bursts satisfying the observed apparent brightness distribution. The crucial point is that the gamma-ray absorption by pair production in the intergalactic diffuse radiation field eliminates bursts from beyond the gamma-ray horizon tau ~ 1, thus drastically reducing the number of bursts at high energies. Our results are consistent with the non-detection of bursts by current experiments in the 100 GeV to 100 TeV energy range. For the earth-bound detector array MILAGRO, we predict a maximal GRB rate of ~ 10 events per year. The Whipple Observatory can detect, under favorable conditions, ~1 event per year. The event rate for the HEGRA array is ~ 0.01 per year. Detection of significantly higher rates of bursts would severely challenge cosmological burst scenarios.

description: We present the Levitation Simulator, a system that enables researchers and designers to iteratively develop and prototype levitation interface ideas in Virtual Reality. This includes user tests and formal experiments. We derive a model of the movement of a levitating particle in such an interface. Based on this, we develop an interactive simulation of the levitation interface in VR, which exhibits the dynamical properties of the real interface. The results of a Fitts' Law pointing study show that the Levitation Simulator enables performance, comparable to the real prototype. We developed the first two interactive games, dedicated for levitation interfaces: LeviShooter and BeadBounce, in the Levitation Simulator, and then implemented them on the real interface. Our results indicate that participants experienced similar levels of user engagement when playing the games, in the two environments. We share our Levitation Simulator as Open Source, thereby democratizing levitation research, without the need for a levitation apparatus.

description: We present an analytical formula for the Bose-Einstein correlations (BEC) which includes effects of both Coulomb and strong final stateinteractions (FSI). It was obtained by using Coulomb wave function together with the scattering partial wave amplitude of the strong interactions describing data on the $s$-wave phase shift. We have proved numerically that this method is equivalent to solving Schrödinger equation with Coulomb and the $s$-wave strong interaction potentials. As an application we have analysed, using our formula which includes the degree of coherence and the long range correlation, the data for $e^+e^-$ annihilations. We have found that the degree of coherence present in our formula approaches approximately unity whereas the long range correlation parameter becomes approximately zero. These results suggest that the physical meanings of the fractional degree of coherence and the long range correlation observed in various other analyses can most probably be attributed to FSI.

The Disadvantages of using a Monitoring System for Air Quality

description: Air quality affects human health as well as visibility. Urban activities, particularly automobile traffic, are a significant contributor to environmental pollution, which is harmful to the general public's health. In order to plan and regulate these operations, public authorities and the general public will eventually need to be able to predict air quality in advance in order to limit the detrimental effects on the environment and human health. Advances in sensor technology and artificial intelligence (AI) have made it possible to predict air quality by accounting for a range of environmental factors.

Weak Gravitational Lensing around Field Galaxies in HST Survey Images

description: Using data from the HST Medium Deep Survey, a long-term Key Project, together with generically similar archived data, we have discovered evidence for weak gravitational `shear' of background field galaxies (I = 22 -- 26) in the vicinity of isolated, foreground galaxies ( I = 15 -- 22), especially those of early type. The statistical lensing is demonstrated by the slight preferential orientation of the major axes of the background galaxies in directions at right angles to the lines joining them to the foreground ones. The detected shear is at the level of $δϕ= 2.5^{o}\pm 1.2^{o}$ averaged over the background galaxies at about ~10 half-light radii from 400 foreground ellipticals, corresponding to a polarization of about 0.04. A positive but less significant result is also reported for foreground spirals. This result excludes the de Vaucouleurs model for the mass distribution of ellipticals, but is consistent with elliptical galaxies having total M/L ~ 100 and extensive dark halos.

description: We present an experimental investigation of stochastic switching of a bistable Josephson junctions array resonator with a resonance frequency in the GHz range. As the device is in the regime where the anharmonicity is on the order of the linewidth, the bistability appears for a pump strength of only a few photons. We measure the dynamics of the bistability by continuously observing the jumps between the two metastable states, which occur with a rate ranging from a few Hz down to a few mHz. The switching rate strongly depends on the pump strength, readout strength and the temperature, following Kramer's law. The interplay between nonlinearity and coupling, in this little explored regime, could provide a new resource for nondemolition measurements, single photon switches or even elements for autonomous quantum error correction.

What information can we obtain from the yield ratio $π^-/π^+$ in heavy-ion collisions ?

description: The recently reported data on the yield ratio $π^-/π^+$ in central rapidity region of heavy-ion collisions are analyzed by theoretical formula which accounts for Coulomb interaction between central charged fragment (CCF) consisting of nearly stopped nucleons with effective charge $Z_{\mbox{\scriptsize eff}}$ and charged pions produced in the same region of the phase space. The Coulomb wave function method is used instead of the usual Gamow factor in order to account for the finite production range of pions, $β$. For Gaussian shape of the pion production sources it results in a quasi-scaling in $β$ and $Z_{\mbox{\scriptsize eff}}$ which makes determination of parameters $β$ and $Z_{\mbox{\scriptsize eff}}$ from the existing experimental data difficult. Only sufficiently accurate data taken in the extreme small $m_{\scriptscriptstyle T}$-$m_π$ region, where this quasi-scaling is broken, could be used for this purpose.

description: We investigate the quarkonium production mechanisms in jets at the LHC, using the Fragmenting Jet Functions (FJF) approach. Specifically, we discuss the jet energy dependence of the $J/ψ$ production cross section at the LHC. By comparing the cross sections for the different NRQCD production channels ($^1S_0^{[8]}$,$^3S_1^{[8]}$,$^3P_J^{[8]}$, and $^3S_1^{[1]}$), we find that at fixed values of energy fraction $z$ carried by the $J/ψ$, if the normalized cross section is a decreasing function of the jet energy, in particular for $z > 0.5$, then the depolarizing $^1S_0^{[8]}$ must be the dominant channel. This makes the prediction made in [Baumgart et al., JHEP 1411, 003 (2014)] for the FJF's also true for the cross section. We also make comparisons between the long distance matrix elements extracted by various groups. This analysis could potentially shed light on the polarization properties of the $J/ψ$ production in high $p_T$ region.

NGC 4244: A Low Mass Galaxy with a Falling Rotation Curve and a Flaring Gas Layer
Creators: name: Olling, Rob P.

description: I present sensitive high resolution HI VLA B+C+D array observations of the edge-on Scd galaxy NGC 4244. The gas layer of NGC 4244 is rather symmetric in all respects, i.e. the surface density distribution, flaring and warping, so that the rotation curve (RC) is determined accurately, despite the fact that i~90^o. The RC rises slowly in the inner 6 kpc, is ~ constant at 100 km/s out to 10kpc, and decreases in Keplerian fashion by 15% at the last measured point at 14 kpc. The RC constrains the stellar mass-to-light ratio to lie between 50 and 100% of the ``maximum-disk'' value. A new technique is presented to determine simultaneously the inclination and the thickness of the gas layer from HI observations which uses the apparent widths at many channels and works for i >= 60^o. The inclination of the un- warped disk is about 84.5 degrees: beyond D25/2 the inclination changes gra- dually till 82.5^o, while at large radii the disk seems to warp back to the plane defined by the inner disk. The gaseous velocity dispersion is roughly constant within the optical disk (8.5+/-1 km/s) and increases slightly beyond. The thickness of the gas layer increases gradually from 0.4 to 1.5 kpc.

description: Generating accurate and efficient predictions for the motion of the humans present in the scene is key to the development of effective motion planning algorithms for robots moving in promiscuous areas, where wrong planning decisions could generate safety hazard or simply make the presence of the robot "socially" unacceptable. Our approach to predict human motion is based on a neural network of a peculiar kind. Contrary to conventional deep neural networks, our network embeds in its structure the popular Social Force Model, a dynamic equation describing the motion in physical terms. This choice allows us to concentrate the learning phase in the aspects, which are really unknown (i.e., the model's parameters) and to keep the structure of the network simple and manageable. As a result, we are able to obtain a good prediction accuracy with a small synthetically generated training set, and the accuracy remains acceptable even when the network is applied in scenarios quite different from those for which it was trained. Finally, the choices of the network are "explainable", as they can be interpreted in physical terms. Comparative and experimental results prove the effectiveness of the proposed approach.

description: We construct log resolutions of pairs on the blow-up of the projective space in an arbitrary number of general points and we discuss the semi-ampleness of the strict transforms. As an application we prove that the abundance conjecture holds for an infinite family of such pairs. For $n+2$ points, these strict transforms are F-nef divisors on the moduli space $\overline{\mathcal{M}}_{0,n+3}$ in a Kapranov's model: we show that all of them are nef.

The Highly Flattened Dark Matter Halo of NGC 4244
Creators: name: Olling, Rob P.
Publisher: name: arXiv
Year: 1996
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: In a previous paper (Olling 1995, \aj, 110, 591; astro-ph/9505002) a method was developed to determine the shapes of dark matter halos of spiral galaxies from an accurate determination of the rotation curve, the flaring of the gas layer and the velocity dispersion in the HI. Here this method is applied to the almost edge-on Scd galaxy NGC 4244 for which the necessary parameters are determined in the accompanying paper (AJ, Aug. 1996; astro-ph/9605110). The observed flaring of the HI beyond the optical disk puts significant constraints on the shape of the dark matter halo, which are almost independent of the stellar mass-to-light ratio. NGC 4244's dark matter halo is found to be highly flattened with a shortest-to-longest axis ratio of 0.2 (-0.1)(+0.3). If the dark matter is disk-like, the data presented in this paper imply that the vertical velocity dispersion of the dark matter must be 10% - 30% larger than the measured tangential dispersion in the HI. Alternatively, the measured flaring curve is consistent with a round halo if the gaseous velocity dispersion ellipsoid is anisotropic. In that case the vertical dispersion of the gas is 50 - 70% of the measured tangential velocity dispersion.

description: We present a novel framework for addressing the nonlinear Landau collision integral in terms of finite element and other subspace projection methods. We employ the underlying metriplectic structure of the Landau collision integral and, using a Galerkin discretization for the velocity space, we transform the infinite-dimensional system into a finite-dimensional, time-continuous metriplectic system. Temporal discretization is accomplished using the concept of discrete gradients. The conservation of energy, momentum, and particle densities, as well as the production of entropy is demonstrated algebraically for the fully discrete system. Due to the generality of our approach, the conservation properties and the monotonic behavior of entropy are guaranteed for finite element discretizations in general, independently of the mesh configuration.

description: [transcription] A Aix ce 8 janvier 1783

c'est par discrétion, Monsieur, que j'ai différé jusqu'à présent de vous offrir les voeux sincères que je fais pour vous à l'occasion de cette nouvelle année et de vous rappeler les sentimens d'attachement et de reconnaissance dont je suis pénétré pour vous et que je vous ai voué pour ma vie. J'ai voulu pour vous être moins à charge laisser passer les premiers jours de l'année.

J'ai vu ces jours passés quelqu'un qui arrive de Nîmes qui m'a assuré que vous jouissiez de la meilleure santé. J'en ai ressenti la plus vive satisfaction et je vous en fais mon compliment bien sincère. Une santé aussi précieuse que la vôtre n'intéresse pas seulement vos amis et ceux qui vous sont attachés. Vous ne devez rien oublier pour la conserver et surtout tâcher de vous préserver des rhumes et des fluxions. c'est là notre fléau à mesure que nous avançons en âge et j'en fais la cruelle expérience.

Ne pensez-vous pas à donner au public l'inscription d'Arles, que je connais par ce qu'en dit le P. Papon dans son 2e vol ? c'est une dette que vous avez contracté envers cette province que ce monument intéresse. S'il était nécessaire que vous vous guindassiez sur des échaffauds et que vous exposassiez une santé précieuse, nous renoncerions volontiers à la connaissance de[fol. 178v] cette inscription quelle précieuse qu'elle soit.

Je finis Monsieur en vous renouvellant l'assurance du sentiment d'attachement de respect dont je suis pénétré pour vous et avec lequel j'ai l'honneur d'être

Monsieur

Votre très humble et très obéissant serviteur.

description: We study the leading $α^\prime$ corrections to the entropy of certain black holes with AdS$_5\times S^5$ asymptotics. We find that, in the supersymmetric limit, the entropy does not receive $α^\prime$ corrections. This result strengthens recent calculations that match the index of $\mathcal{N}=4$ Super-Yang-Mills with the corresponding partition function in the supersymmetric limit. In the small temperature regime, we find that the entropy corrections are concordant with the weak gravity conjecture.

description: Due to the orbifold singularities, the intersection numbers on the moduli space of curves $\bar{\sM}_{g,n}$ are in general rational numbers rather than integers. We study the properties of the denominators of these intersection numbers and their relationship with the orders of automorphism groups of stable curves. In particular, we prove a conjecture of Itzykson and Zuber. We also present a conjectural multinomial type numerical property for Hodge integrals.

Radiation Forces on Dust Envelopes

description: We address in detail the radiation forces on spherical dust envelopes around luminous stars, and numerical solutions for these forces, as a first step toward more general dust geometries. Two physical quantities, a normalized force and a force-averaged radius, suffice to capture the overall effects of radiation forces; these combine to yield the radiation term in the virial theorem. In addition to the optically thin and thick regimes, the wavelength dependence of dust opacity allows for an intermediate case in which starlight is easily trapped but infrared radiation readily escapes. Scattering adds a non-negligible force in this intermediate regime. We address all three regimes analytically and provide approximate formulae for the force parameters, for arbitrary optical depth and inner dust temperature. Turning to numerical codes, we examine the convergence properties of the Monte Carlo code Hyperion run in Cartesian geometry. We calibrate both Hyperion and our analytical estimate using the DUSTY code, run in spherical geometry. We find that Monte Carlo codes tend to underestimate the radiation force when the mean free path of starlight is not well resolved, as this causes the inner dust temperature, and therefore the inner Rosseland opacity, to be too low. We briefly discuss implications for more complicated radiation transfer problems.

description: We have developed a new stellar population synthesis model designed to study early-type galaxies. It provides optical and near-infrared colors, and line indices for 25 absorption lines. It can synthesize single age, single metallicity stellar populations or follow the galaxy through its evolution from an initial gas cloud to the present time. The model incorporates the new isochrones of the Padova group and the latest stellar spectral libraries. The model has been extensively compared with previous ones in the literature to establish its accuracy as well as the accuracy of this kind of models in general. Using the evolutionary version of the model we find that we cannot fit the most metal-rich elliptical galaxies if we keep the IMF constant and do not allow infall of gas. We do however reproduce the results of Arimoto \& Yoshii (1986) for the evolution of the gas, and produce colors, and, for the first time with this type of models, absorption line-strengths. It is in fact possible to fit the data for the elliptical galaxies by varying the IMF with time. Our numerical model is in good broad agreement with the analytical 'simple model'. In the present paper we describe the model, and compare a few key observables with new data for three early-type {\em standard} galaxies. However the data, as well as our fits, will be discussed in much more detail in a second paper (Vazdekis {\it et al.} 1996), where some conclusions will be drawn about elliptical galaxies on the basis of this model.
