description: We present CO observations of a large sample of ultraluminous IR galaxies out to z = 0.3. Most of the galaxies are interacting, but not completed mergers. All but one have high CO(1-0) luminosities, log(Lco [K-km/s-pc^2]) = 9.92 +/- 0.12. The dispersion in Lco is only 30%, less than that in the FIR luminosity. The integrated CO intensity correlates Strongly with the 100 micron flux density, as expected for a black body model in which the mid and far IR radiation are optically thick. We use this model to derive sizes of the FIR and CO emitting regions and the enclosed dynamical masses. Both the IR and CO emission originate in regions a few hundred parsecs in radius. The median value of Lfir/Lco = 160 Lsun/(K-km/s-pc^2), within a factor of two of the black body limit for the observed FIR temperatures. The entire ISM is a scaled up version of a normal galactic disk with densities a factor of 100 higher, making even the intercloud medium a molecular region. Using three different techniques of H2 mass estimation, we conclude that the ratio of gas mass to Lco is about a factor of four lower than for Galactic molecular clouds, but that the gas mass is a large fraction of the dynamical mass. Our analysis of CO emission reduces the H2 mass from previous estimates of 2-5e10 Msun to 0.4-1.5e10 Msun, which is in the range found for molecular gas rich spiral galaxies. A collision involving a molecular gas rich spiral could lead to an ultraluminous galaxy powered by central starbursts triggered by the compression of infalling preexisting GMC's.

description: Recently, a new technique for measuring short-range NN correlations in nuclei (NN SRCs) was reported by the E850 collaboration, using data from the EVA spectrometer at the AGS at Brookhaven Nat. Lab. In this talk, we will report on a larger set of data from new measurement by the collaboration, utilizing the same technique. This technique is based on a very simple kinematic approach. For quasi-elastic knockout of protons from a nucleus ($^{12}$C(p,2p) was used for the current work), we can reconstruct the momentum {\bf p$_f$} of the struck proton in the nucleus before the reaction, from the three momenta of the two detected protons, {\bf p$_1$} and {\bf p$_2$} and the three momentum of the incident proton, {\bf p$_0$} : {\bf p$_f$} = {\bf p$_1$} + {\bf p$_2$} - {\bf p$_0$} If there are significant n-p SRCs, then we would expect to find a neutron with momentum -{\bf p$_f$} in coincidence with the two protons, provided {\bf p$_f$} is larger than the Fermi momentum $k_F$ for the nucleus (${\sim}$220 MeV/c for $^{12}$C). Our results reported here confirm the earlier results from the E850 collaboration.

description: We investigate electronic transport through a graphene $n$-$p$ junction in the quantum Hall effect regime at high perpendicular magnetic field, when the filling factors in the $n$-doped and $p$-doped regions are fixed to 2 and -2 respectively. We compute numerically the conductance $G$, the noise $Q$ and the Fano factor $F$ of the junction when inelastic effects are included along the interface in a phenomenological way, by means of fictitious voltage probes. Using a scaling approach, we extract the system coherence length $L_ϕ$ and describe the full crossover between the coherent limit ($W\ll L_ϕ$) and the incoherent limit ($W\gg L_ϕ$), $W$ being the interface length. While $G$ saturates at the value $e^2/h$ in the incoherent regime, $Q$ and $F$ are found to vanish exponentially for large length $W$. Corrections due to disorder are also investigated. Our results are finally compared to available experimental data.

description: Adversarial multi-robot problems, where teams of robots compete with one another, require the development of approaches that span all levels of control and integrate algorithms ranging from low-level robot motion control, through to planning, opponent modeling, and multiagent learning. Smallsize robot soccer, a league within the RoboCup initiative, is a prime example of this multi-robot team adversarial environment. In this paper, we describe some of the algorithms and approaches of our robot soccer team, CMDragons’02, developed for RoboCup 2002. Our team represents an integration of many components, several of which that are in themselves state-of-theart, into a framework designed for fast adaptation and response to the changing environment.

description: The present spectroscopic study of the ultraviolet coronal emission in a polar hole, detected on April 6-9, 1996 with the Ultraviolet Coronagraph Spectrometer aboard the SOHO spacecraft, identifies the inter-plume lanes and background coronal hole regions as the channels where the fast solar wind is preferentially accelerated. In inter-plume lanes, at heliocentric distance 1.7 \rsun, the corona expands at a rate between 105 km/s and 150 km/s, that is, much faster than in plumes where the outflow velocity is between 0 km/s and 65 km/s. The wind velocity is inferred from the Doppler dimming of the O VI $λλ$ 1032, 1037 Ålines, within a range of values, whose lower and upper limit corresponds to anisotropic and isotropic velocity distribution of the oxygen coronal ions, respectively.

Démographie

description: Dans les pays industrialisés, après des décennies de croissance, la circulation automobile a stagné dans les années 2000. Phénomène attribué aux facteurs économiques classiques (revenus, prix des carburants) et à une certaine ré-urbanisation, mais aussi à des facteurs démographiques (vieillissement, allongement des étapes du cycle de vie). Une modeste reprise économique et la baisse du prix du pétrole en 2014 ont favorisé un certain renouveau de la croissance du trafic. Il n’y a pas de consensus sur les causes du plafonnement de la circulation et sur sa persistance, sauf que ses causes sont multiples (démographie, densité urbaine, revenu, prix, politiques, technologie, accessibilité, mentalités). Nous ne prétendons pas pouvoir prendre en compte tous ces facteurs mais proposons une approche prospective démographique qui considère au niveau national, la croissance de la population, les changements de comportement à travers les générations, ainsi que les effets de période représentés par le revenu réel par unité de consommation et le prix du carburant. Nous avons déjà traité cette question via des modèles Âge-Période-Cohorte (APC). Nous comparons ici les résultats d´un modèle APC avec ceux d’un modèle Espérance de vie-Période-Cohorte (EPC) en remplaçant l’âge par l’espérance de vie, contournant ainsi la sur-détermination du modèle APC. Nous projetons le km annuel par adulte à partir des données du panel Parc-Auto Kantar-SOFRES 1994-2018. Nous proposons ainsi un cadre méthodologique de prévision avant la pandémie de Covid-19 et en l’absence de ruptures de tendances. À court terme (2007-2017), APC reconstitue mieux les kilomètres parcourus que le modèle EPC surtout avant la soixantaine, ce qui indiquerait que l’augmentation de l’espérance de vie a peu d’influence sur les comportements de mobilité. Mots-clés motorisation individuelle, kilométrage parcouru, espérance de vie, facteurs démographiques et économiques, prospective N.B. : Le présent article s´inspire largement d´une communication présentée en mai 2019 à Mumbai pour la Conférence Mondiale sur la Recherche dans les Transports [1].

description: This paper asks how many cooperating homogeneous robots are required to perform a block pushing task in a known environment. This task is particularly challenging in the presence of a highly cluttered obstacle field where the connectivity of the robots’ free configuration space depends on the block’s configuration. In order to simplify the problem, we define an equivalence relation over block configurations based on the connectivity of the robots’ free configuration space. We build a data structure that captures the relationships among the resulting equivalence classes, and then we encode constraints into the data structure that must be satisfied for the robots to be able to push the block between equivalence classes. We present an algorithm that operates on this data structure and uses existing optimization techniques to solve several variants of the minimum sufficient robots problem. Next, we give an implementation of this algorithm for an environment consisting of axis-aligned rectangles. Additionally, we provide a complete planner that finds a feasible path for the block in this environment.

description: We investigate the mass spectra of the lowest-lying singly heavy baryons, based on the self-consistent chiral quark-soliton model. We take into account the rotational $1/N_c$ and strange current quark mass ($m_{\mathrm{s}}$) corrections. Regarding $m_{\mathrm{s}}$ as a small perturbation, we expand the effective chiral action to the second order with respect to $m_{s}$. The mass spectra of heavy baryons are computed and compared with the experimental data. Fitting the classical masses of the heavy baryon to the center mass of each representation, we determine the masses of all the lowest-lying singly heavy baryons. We predict the mass of the $Ω_b^*$ baryon to be 6081.9 MeV, when the second-order $m_{\mathrm{s}}$ corrections are included.

description: Recently, the manufacturing sector in Zimbabwe has been failing to operate at full capacity because of a turbulent economic environment which is not conducive for business. Consequently, the deteriorating business environment has led to the failure of the sector to reward its employees appropriately. The current research was designed to explore extrinsic rewards, employee motivation and organisational effectiveness in turbulent economic times with specific reference to the Zimbabwean manufacturing sector. A self-administered questionnaire was used to collect data from a systematic sample of 140 employees. The findings of this study showed that extrinsic rewards have a positive and significant relationship with employee motivation and organisational effectiveness. In addition, the study found a positive and significant relationship between employee motivation and organisational effectiveness. Recommendations have been provided on how the manufacturing sector can improve employee motivation and organisational effectiveness. It is envisaged that this study could assist top management with the tools to motivate the workforce and subsequently achieve organisational effectiveness. Furthermore, this study has contributed to the literature on extrinsic rewards, employee motivation and organisation effectiveness from the developing world where most businesses are failing to perform optimally because of prevailing economic challenges.

description: Path planning for multiple mobile robots is complicated by the presence of a dynamic environment, in which obstacles and other robots are moving. Centralized approaches are too computationally intensive for real-time response. Decoupled approaches which perform individual preplanning, conflict resolution, and reactive obstacle avoidance for each robot, can be globally inefficient. We propose a novel mission coordination architecture, CPAD (Checkpoint/Priority/ Action Database), which performs path planning via checkpoint and dynamic priority assignment, using statistical estimates of the environment’s motion structure in order to make both preplanning and reactive behaviors more efficient. Simulation is used to validate and illustrate the approach.

In comparison with previously published (pi+,pp) data on the same targets and at the same beam energies, kinematic regions were identified in which the neutron pickup process n+p->d dominated the observed deuteron yield. The importance of this mechanism increases with energy, contributing half of the observed cross section at 165 MeV. The contribution of direct quasi-triton absorption is significant only at 100 MeV.

description: Elliptic flow from nuclear collisions is a hadronic observable sensitive to the early stages of system evolution. We report first results on elliptic flow of charged particles at midrapidity in Au+Au collisions at sqrt(s_NN)=130 GeV using the STAR TPC at RHIC. The elliptic flow signal, v_2, averaged over transverse momentum, reaches values of about 6% for relatively peripheral collisions and decreases for the more central collisions. This can be interpreted as the observation of a higher degree of thermalization than at lower collision energies. Pseudorapidity and transverse momentum dependence of elliptic flow are also presented.

description: According to the experience of developed countries, international trade operations are one of the main links in ensuring the development of the country's economy. The expansion of the economy's use of innovative scientific and technical achievements, the increasing need of countries for international labor migration, reveals the need to further strengthen the integration of the world economy in international trade activities. The most important point of this process goes back to the export-import operations and is manifested in their implementation. Expanding the volume of export-import operations and ensuring their balance in the further strengthening of Uzbekistan's integration into the world economy is gaining importance in the international economic relations of our country.
Evidence for Stellar Streaming in the Cores of Elliptical Galaxies: A Kinematic Signature of Mergers?

Publisher: name: arXiv

description: We present evidence for non-Gaussian velocity fields within the cores of luminous elliptical galaxies. This evidence is based upon high signal-to-noise, medium-resolution spectroscopy of the cores of early-type members of the Virgo and Coma clusters obtained with the WIYN 3.5-m telescope. The Virgo data were acquired using an integral-field unit (DensePak) allowing the velocity field to be sampled over a variety of spatial scales. The Coma data were obtained through single, 2-arcsec diameter fibers. The cross-correlation profiles of luminous ellipticals show considerable structure, often having several features with amplitudes as high as 10% that of the cross-correlation peak itself. This structure is most obvious within a radius of 1.5 arcsec (at Virgo), or < 100 pc, and is nearly undetectable when the data are binned over R < 15 arcsec, or < 1 kpc. Similar features are found in the single-fiber spectra of the luminous ellipticals in the Coma Cluster suggesting they are ubiquitous to giant ellipticals. Interesting, only the most luminous elliptical galaxies show this phenomena; the central regions of lower luminosity ellipticals have regular, Gaussian-like profiles. We interpret this kinematic structure as ``stellar streaming'' and suggest that this phenomena could be a relic signature of the merger history of luminous elliptical galaxies.

In this paper, we present a set of 1800 galaxy mock catalogues designed to match the Dark Energy Survey Year-1 BAO sample (Crocce et al. 2017) in abundance, observational volume, redshift distribution and uncertainty, and redshift dependent clustering. The simulated samples were built upon HALOGEN (Avila et al. 2015) halo catalogues, based on a $2LPT$ density field with an exponential bias. For each of them, a lightcone is constructed by the superposition of snapshots in the redshift range $0.45

description: The theoretical merits of longitudinal polarization asymmetries of electron-positron annihilation into two final fermions at future colliders are examined, using a recently proposed theoretical description. A number of interesting features, valid for searches of virtual effects of new physics, is underlined, that is reminiscent of analogous properties valid on top of $Z$ resonance. As an application to a concrete example, we consider the case of a model with triple anomalous gauge couplings and show that the additional information provided by these asymmetries would lead to a drastic reduction of the allowed domain of the relevant parameters.

description: Markarian 421 is a high-peaked BL Lac object and it has undergone many strong outbursts since its discovery as a TeV source in 1992. Markarian 421 has been stud- ied intensively and was observed by various Cherenkov tele- scope arrays ever since. The outbursts of April 2004 observed by the Whipple telescope and of February 2010 by the HESS telescopes are explained well in this work by using the photohadronic model. To account for the attenuation of these high- energy gamma-rays by the extragalactic background light (EBL), we use template EBL models. The intrinsic spectrum of each epoch is different even though the high-energy protons have almost the same spectral index. We observe that this difference in intrinsic spectra is due to the change in the spectral index of the low-energy tail of the synchrotron self Compton (SSC) photons during different epochs of flaring. Our results show that the contemporaneous multiwavelength observations, particularly in the low-energy tail region of the SSC emission of the source, are important in explaining the flaring phenomenon.

RESIDUAL DENSE SWIN TRANSFORMER FOR CONTINUOUS DEPTH-INDEPENDENT ULTRASOUND IMAGING

Publisher: name: IEEE Signal Processing Society
Year: 2024

description: Ultrasound imaging is crucial for evaluating organ morphology and function, yet depth adjustment can degrade image quality and field-of-view, presenting a depth-dependent dilemma. Traditional interpolation-based zoom-in techniques often sacrifice detail and introduce artifacts. Motivated by the potential of arbitrary-scale super-resolution to naturally address these inherent challenges, we present the Residual Dense Swin Transformer Network (RDSTN), designed to capture the non-local characteristics and long-range dependencies intrinsic to ultrasound images. It comprises a linear embedding module for feature enhancement, an encoder with shifted-window attention for modeling non-locality, and an MLP decoder for continuous detail reconstruction. This strategy streamlines balancing image quality and field-of-view,
which offers superior textures over traditional methods. Experimentally, RDSTN outperforms existing approaches while requiring fewer parameters. In conclusion, RDSTN shows promising potential for ultrasound image enhancement by overcoming the limitations of conventional interpolation-based methods and achieving depth-independent imaging.

description: We consider the problem of multi-robot coordination subject to constraints on the configuration. Specifically, we examine the case in which a mobile network of robots must search, survey, or cover an environment while remaining connected. While many algorithms utilize continual connectivity for such tasks, we relax this requirement and introduce the idea of periodic connectivity, where the network must regain connectivity at a fixed interval. We show that, in some cases, this problem reduces to the well-studied NP-hard multi-robot informative path planning (MIPP) problem, and we propose an online algorithm that scales linearly in the number of robots and allows for arbitrary periodic connectivity constraints. We prove theoretical performance guarantees and validate our approach in the coordinated search domain in simulation and in real-world experiments. Our proposed algorithm significantly outperforms a gradient method that requires continual connectivity and performs competitively with a market-based approach, but at a fraction of the computational cost.
The nature of the intrinsic spectra from the VHE emission of H 2356-309 and 1ES 1101-232

description: The VHE emission from the HBLs H 2356-309 and 1ES 1101-232 were observed by HESS telescopes during 2004--2007. Particularly the observation in 2004 from H 2356-309 and during 2004--2005 from 1ES 1101-232 were analyzed to derive strong upper limits on the EBL which was found to be consistent with the lower limits from the integrated light of resolved galaxies. Here we have used the photohadronic model corroborated by two template EBL models to fit the observed VHE gamma-ray data from these two HBLs and to predict their intrinsic spectra. We obtain very good fit to the VHE spectra of these two HBLs. However, the predicted intrinsic spectra are different for each EBL model. For the HBL H 2356-309, we obtain a flat intrinsic spectrum and for 1ES 1101-232 the spectrum is mildly harder than 2 but much softer than 1.5.

description: This article summarizes ideas on representing translational friction and computing reaction forces in configuration space. The configuration space of an object is the parameter space describing the object's degrees of freedom. Kinematic constraints imposed on the object by obstacles in the environment may be represented as hypersurfaces in the configuration space. Physical and dynamical constraints such as those imposed by friction may be represented as constraints in the generalized force space that accompanies the configuration space. This article develops a representation of friction in this generalized force space that is analogous to the classical friction cone in real space.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: Here we consider the problem of low-flying rotorcraft that must perform various missions such as navigating to specific goal points while avoiding obstacles, looking for acceptable landing sites or performing continuous surveillance. Not all of such missions can be expressed as safe, goal seeking, partly because in many cases there isn't an obvious goal. Rather than developing singular solutions to each mission, we seek a generalized formulation that enables us to express a wider range of missions. Here we propose a framework that allows for multiple objectives to be considered simultaneously and discuss corresponding planning algorithms that are capable of running in realtime on autonomous air vehicles. The algorithms create a set of initial hypotheses that are then optimized by a sub-gradient based trajectory algorithm that optimizes the multiple objectives, producing dynamically feasible trajectories. We have demonstrated the feasibility of our approach with changing cost functions based on newly discovered information. We report on results in simulation of a system that is tasked with navigating safely between obstacles while searching for an acceptable landing site.

description: Estimating the joint probability mass function (PMF) of a set of random variables lies at the heart of statistical learning and signal processing. Without structural assumptions, such as modeling the variables as a Markov chain, tree, or other graphical model, joint PMF estimation is often considered mission impossible - the number of unknowns grows exponentially with the number of variables. But who gives us the structural model? Is there a generic, `non-parametric' way to control joint PMF complexity without relying on a priori structural assumptions regarding the underlying probability model? Is it possible to discover the operational structure without biasing the analysis up front? What if we only observe random subsets of the variables, can we still reliably estimate the joint PMF of all? This paper shows, perhaps surprisingly, that if the joint PMF of any three variables can be estimated, then the joint PMF of all the variables can be provably recovered under relatively mild conditions. The result is reminiscent of Kolmogorov's extension theorem - consistent specification of lower-dimensional distributions induces a unique probability measure for the entire process. The difference is that for processes of limited complexity (rank of the high-dimensional PMF) it is possible to obtain complete characterization from only three-dimensional distributions. In fact not all three-dimensional PMFs are needed; and under more stringent conditions even two-dimensional will do. Exploiting multilinear algebra, this paper proves that such higher-dimensional PMF completion can be guaranteed - several pertinent identifiability results are derived. It also provides a practical and efficient algorithm to carry out the recovery task. Judiciously designed simulations and real-data experiments on movie recommendation and data classification are presented to showcase the effectiveness of the approach.
Direct Photon Production in 158 AGeV Pb+Pb Collisions

description: A measurement of direct photon production in Pb+Pb collisions at 158 AGeV has been carried out in the CERN WA98 experiment. The invariant yield of direct photons in central collisions is extracted as a function of transverse momentum in the interval 0.5 < pT < 4 GeV/c. A significant direct photon signal, compared to statistical and systematical errors, is seen at pT > 1.5 GeV/c. The results constitute the first observation of direct photons in ultrarelativistic heavy-ion collisions which could be significant for diagnosis of quark gluon plasma formation.

Electron Firehose instability and acceleration of electrons in solar flares
Creators: name: Paesold, Gunnar

Publisher: name: arXiv
Year: 2000
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: An electron distribution with a temperature anisotropy T_par/T_perp > 1 can lead to the Electron Firehose instability (Here par and perp denote directions relative to the background magnetic field B_0). Since possible particle acceleration mechanisms in solar flares exhibit a preference of energizing particles in parallel direction, such an anisotropy is expected during the impulsive phase of a flare. The properties of the excited waves and the thresholds for instability are investigated by using linearized kinetic theory. These thresholds were connected to the pre-flare plasma parameters by assuming an acceleration model acting exclusively in parallel direction. For usually assumed pre-flare plasma conditions the electrons become unstable during the acceleration process and lefthand circularly polarized waves with frequencies of about the proton gyrofrequency are excited at parallel propagation. Indications have been found, that the largest growth rates occur at oblique propagation and the according frequencies lie well above the proton gyrofrequency.

Unpacking the Social Media Bot: A Typology to Guide Research and Policy

description: Amidst widespread reports of digital influence operations during major elections, policymakers, scholars, and journalists have become increasingly interested in the political impact of social media 'bots.' Most recently, platform companies like Facebook and Twitter have been summoned to testify about bots as part of investigations into digitally-enabled foreign manipulation during the 2016 US Presidential election. Facing mounting pressure from both the public and from legislators, these companies have been instructed to crack down on apparently malicious bot accounts. But as this article demonstrates, since the earliest writings on bots in the 1990s, there has been substantial confusion as to exactly what a 'bot' is and what exactly a bot does. We argue that multiple forms of ambiguity are responsible for much of the complexity underlying contemporary bot-related policy, and that before successful policy interventions can be formulated, a more comprehensive understanding of bots --- especially how they are defined and measured --- will be needed. In this article, we provide a history and typology of different types of bots, provide clear guidelines to better categorize political automation and unpack the impact that it can have on contemporary technology policy, and outline the main challenges and ambiguities that will face both researchers and legislators concerned with bots in the future.

On the Evolution of the Globular Cluster Luminosity Function: The Differences
Creators: name: Gnedin, Oleg Y.
Publisher: name: arXiv
Year: 1996
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We consider the observational signature of the dynamical effects on the luminosity function of globular clusters. For the three best studied systems, in Milky Way, M31, and M87, there is a statistically significant difference between the inner and outer population of globular clusters. In all cases the inner clusters are on average brighter than the outer clusters ($0.26 < Δm_0 < 0.84$) and have a smaller dispersion in magnitudes ($0.04 < Δσ< 0.53$), with the larger differences for the local, better observed samples. The differences are of the type that would be expected if the inner population had been depleted by tidal shocks. The results suggest that the inner population suffers substantial evolution from its initial distribution and cannot not be used as a standard candle without correction for dynamical evolution.
