description: We investigate spectral behavior of phonon spectral functions in an interacting multi-component hot carrier plasma. Dielectric polarization functions are formulated so that they satisfy Dyson equations of the effective interactions among plasma components. We find a useful sum rule giving simple relation between plasma-species resolved dielectric functions. Spectral analysis of various phonon spectral functions is performed considering carrier-phonon channels of polar and nonpolar optical phonons, acoustic deformation-potential, and piezoelectric Coulomb couplings. Effects of phonon self-energy corrections are examined at finite temperature within a random phase approximation extended to include the effects of dynamic screening, plasmon--phonon coupling, and local-field corrections of the plasma species. We provide numerical data for the case of a photo-generated electron-hole plasma formed in a wurtzite GaN. Our result shows clear significance of the multiplicity of the plasma species in the dielectric response and phonon spectral functions of a multi-component plasma.

description: Hydrodynamics analysis of waves in two-dimensional degenerate electron gas with the account of separate spin evolution is presented. The transverse electric field is included along with the longitudinal electric field. The Coulomb exchange interaction is included in the analysis. In contrast with the three-dimensional plasma-like mediums the contribution of the transverse electric field is small. We show the decrease of frequency of both the extraordinary (Langmuir) wave and the spin-electron acoustic wave due to the exchange interaction. Moreover, spin-electron acoustic wave has negative dispersion at the relatively large spin-polarization. Corresponding dispersion dependencies are presented and analyzed.

description: We provide evidence that gallium purity is the primary impediment to attainment of ultra-high mobility in a two-dimensional electron gas (2DEG) in AlGaAs/GaAs heterostructures grown by molecular beam epitaxy (MBE). The purity of gallium can be enhanced dramatically by in-situ high temperature outgassing within an operating MBE. Based on analysis of data from an initial growth campaign in a new MBE system and modifications employed for a 2nd growth campaign, we have produced 2DEGs with low temperature mobility in excess of 35x10^6cm2/Vs at density n=3.0x10^11/cm2 and mobility 18x10^6cm2/Vs at n=1.1x1011/cm2. Our 2nd campaign data indicate that gallium purity remains the factor currently limiting mobility <40x10^6cm2/Vs. We describe strategies to overcome this limitation.

description: We study the characteristics of the TeV binary LS I +61$^\circ$ 303 in radio, soft X-ray, hard X-ray, and gamma-ray (GeV and TeV) energies. The long term variability characteristics are examined as a function of the phase of the binary period of 26.496 days as well as the phase of the super orbital period of 1626 days, dividing the observations into a matrix of 10$\times$10 phases of these two periods. It is found that the long term variability can be described by a sine function of the super orbital period, with the phase and amplitude systematically varying with the binary period phase. We also find a definite wavelength dependent change in this variability description. To understand the radiation mechanism, we define three states in the orbital/ super orbital phase matrix and examine the wide band spectral energy distribution. The derived source parameters indicate that the emission geometry is dominated by a jet structure showing a systematic variation with the orbital/ super orbital period. We suggest that LS I +61$^\circ$ 303 is likely to be a micro-quasar with a steady jet.

description: Negative feedback from active galactic nuclei (AGN) is considered a key mechanism in shaping galaxy evolution. Fast, extended outflows are frequently detected in the AGN host galaxies at all redshifts and luminosities, both in ionised and molecular gas. However, these outflows are only "potentially" able to quench star formation and we are still missing a decisive evidence of negative feedback in action. Here we present Spectrograph for INtegral Field Observations in the Near Infrared (SINFONI) H- and K-band integral-field spectroscopic observations of two quasars at $z\sim$2.4 characterised by fast, extended outflows detected through the [OIII]$λ$5007 line (Carniani et al. 2015). The high signal-to-noise ratio of our observations allows us to identify faint narrow (FWHM $< 500$ km/s), and spatially extended components in [OIII]$λ$5007 and H$α$ emission associated with star formation in the host galaxy. Such star-formation powered emission is spatially anti-correlated with the fast outflows. The ionised outflows therefore appear to be able to suppress star formation in the region where the outflow is expanding. However the detection of narrow, spatially-extended H$α$ emission indicates star formation rates of at least $\sim 50-90$ M$_{\odot}$/yr, suggesting either that AGN feedback does not affect the whole galaxy or that many feedback episodes are required before star formation is completely quenched. On the other hand, the narrow H$α$ emission extending along the edges of the outflow cone may lead also to a positive feedback interpretation. Our results highlight the possible twofold role of galaxy-wide outflows in host galaxy evolution.

description: Contexte et objectif. L’observance de la friction hydro-alcoolique doit constamment faire l’objet de travaux de suivi, aux urgences particulièrement, où l’affluence explose et où les soignants ont de plus en plus de mauvaises raisons de négliger les précautions standard. Un travail commun entre urgentistes et hygiénistes a été mené dans un établissement public, en appliquant un outil de diagnostic des freins à la friction afin d’améliorer son observance. Méthode utilisée. Un auto-questionnaire listant 17 freins issus de la littérature a été distribué aux professionnels des urgences. Ils devaient choisir tous les freins les concernant, et désigner celui considéré comme leur frein principal. Des mesures répondant aux freins majoritairement cités ont ensuite été appliquées afin de les contourner et d’optimiser l’observance de la friction hydro-alcoolique à travers l’indicateur hospitalier de consommation. Principaux résultats. Les freins identifiés et jugés contournables étaient les problèmes de tolérance, la disponibilité des solutions hydro-alcooliques (SHA) et la crainte d’une toxicité, identiques à ceux retrouvés dans l’analyse multicentrique concomitante utilisant le même outil. Les actions menées localement ont conduit à une augmentation inédite de l’indicateur de consommation des SHA du service étudié avec 28 points gagnés en trois trimestres. Conclusion. Cette enquête a permis de communiquer en interne au sujet de la friction, d’écouter les professionnels exprimer leurs difficultés et de trouver des solutions concrètes. La démarche, menée à l’échelle d’un service, paraît à la fois généralisable et d’intérêt au vu des résultats obtenus. Sous réserve d’adaptations au contexte local, elle pourrait inspirer d’autres services des urgences en France.

description: A study released by the Google Scholar team found an apparently increasing fraction of citations to old articles from studies published in the last 24 years (1990-2013). To demonstrate this finding we conducted a complementary study using a different data source (Journal Citation Reports), metric (aggregate cited half-life), time spam (2003-2013), and set of categories (53 Social Science subject categories and 167 Science subject categories). Although the results obtained confirm and reinforce the previous findings, the possible causes of this phenomenon keep unclear. We finally hypothesize that first page results syndrome in conjunction with the fact that Google Scholar favours the most cited documents are suggesting the growing trend of citing old documents is partly caused by Google Scholar.

A geometric Hamilton--Jacobi theory for a Nambu--Poisson structure

Year: 2016
Subjects: subject: Mathematical Physics (math-ph)

description: The Hamilton-Jacobi theory is a formulation of Classical Mechanics equivalent to other formulations as Newton's equations, Lagrangian or Hamiltonian Mechanics. It is particulary useful for the identification of conserved quantities of a mechanical system. The primordial observation of a geometric Hamilton-Jacobi equation is that if a Hamiltonian vector field $X_{H}$ can be projected into the configuration manifold by means of a 1-form $dW$, then the integral curves of the projected vector field $X_{H}^{dW}$can be transformed into integral curves of $X_{H}$ provided that $W$ is a solution of the Hamilton-Jacobi equation. This interpretation has been applied to multiple settings: in nonhonolomic, singular Lagrangian Mechanics and classical field theories. Our aim is to apply the geometric Hamilton-Jacobi theory to systems endowed with a Nambu-Poisson structure. The Nambu-Poisson structure has shown its interest in the study physical systems described by several Hamiltonian functions. In this way, we will apply our theory to two interesting examples in the Physics literature: the third-order Kummer-Schwarz equations and a system of $n$ copies of a first-order differential Riccati equation. From these examples, we retrieve the original Nambu bracket in three dimensions and a generalization of the Nambu bracket to $n$ dimensions, respectively.

Synchronization failure caused by interplay between noise and network heterogeneity

Year: 2016
Subjects: subject: Adaptation and Self-Organizing Systems (nlin.AO)

description: We investigate synchronization in complex networks of noisy phase oscillators. We find that, while too weak a coupling is not sufficient for the whole system to synchronize, too strong a coupling induces a nontrivial type of phase slip among oscillators, resulting in synchronization failure. Thus, an intermediate coupling range for synchronization exists, which becomes narrower when the network is more heterogeneous. Analyses of two noisy oscillators reveal that nontrivial phase slip is a generic phenomenon when noise is present and coupling is strong. Therefore, the low synchronizability of heterogeneous networks can be understood as a result of the difference in effective coupling strength among oscillators with different degrees; oscillators with high degrees tend to undergo phase slip while those with low degrees have weak coupling strengths that are insufficient for synchronization.

description: This paper strives for video event detection using a representation learned from deep convolutional neural networks. Different from the leading approaches, who all learn from the 1,000 classes defined in the ImageNet Large Scale Visual Recognition Challenge, we investigate how to leverage the complete ImageNet hierarchy for pre-training deep networks. To deal with the problems of over-specific classes and classes with few images, we introduce a bottom-up and top-down approach for reorganization of the ImageNet hierarchy based on all its 21,814 classes and more than 14 million images. Experiments on the TRECVID Multimedia Event Detection 2013 and 2015 datasets show that video representations derived from the layers of a deep neural network pre-trained with our reorganized hierarchy i) improves over standard pre-training, ii) is complementary among different reorganizations, iii) maintains the benefits of fusion with other modalities, and iv) leads to state-of-the-art event detection results. The reorganized hierarchies and their derived Caffe models are publicly available at http://tinyurl.com/imagenetshuffle.

description: La rougeole est une maladie éruptive systémique avec plusieurs caractéristiques pathogènes uniques et des complications spécifiques. Elle reste l’un des grands fléaux infectieux dans de nombreuses parties du monde malgré la disponibilité d’un vaccin à virus vivant atténué sûr et efficace. La France est l’un des pays où la rougeole est encore présente. De transmission aérienne et manuportée, la rougeole est l’une des maladies virales les plus contagieuses, nécessitant une couverture vaccinale supérieure à 95% avec deux doses de vaccin pour en permettre l’élimination. La couverture vaccinale des professionnels de santé (PS) est actuellement insuffisante, et les données les plus récentes estiment à 15% la proportion de PS qui restent réceptifs à la rougeole en France. Les recommandations concernant la conduite à tenir autour d’un ou plusieurs cas de rougeole ont été revues en septembre 2018 (instruction DGS/SP/SP1/2018/205) et sont rappelées ici. Dans le contexte d’une crise sanitaire sans précédent, liée à l’émergence du Sars-CoV-2, les six régions de l’Organisation mondiale de la santé ont signalé plusieurs interruptions de campagnes de vaccination contre la rougeole. La pandémie de Covid-19 laisse un héritage critique, un « gap » immunitaire, en particulier dans de nombreux pays vulnérables, mettant un nouveau frein à l’élimination, donc à l’éradication possible de la rougeole. Cet article fait le point sur la situation actuelle de la rougeole en France, tant dans la communauté qu’en milieu hospitalier, et sur les enjeux de la protection vaccinale vis-à-vis de ce virus.

description: Using first-principles calculations based on density functional theory, we have studied the mechanical, electronic, and magnetic properties of Heusler alloys, namely, Ni$_{2}BC$ and Co$_{2}BC$ ($B$ = Sc, Ti, V, Cr and Mn as well as Y, Zr, Nb, Mo and Tc; $C$ = Ga and Sn). On the basis of electronic structure (density of states) and mechanical properties (tetragonal shear constant), as well as magnetic interactions (Heisenberg exchange coupling parameters), we probe the properties of these materials in detail. We calculate the formation energy of these alloys in the (face-centered) cubic austenite structure to probe the stability of all these materials. From the energetic point of view, we have studied the possibility of the electronically stable alloys having a tetragonal phase lower in energy compared to the respective cubic phase. A large number of the magnetic alloys is found to have the cubic phase as their ground state. On the other hand, for another class of alloys, the tetragonal phase has been found to have lower energy compared to the cubic phase. Further, we find that the values of tetragonal shear constant show a consistent trend : a high positive value for materials not prone to tetragonal transition and low or negative for others. In the literature, materials, which have been seen to undergo the martensite transition, are found to be metallic in nature. We probe here if there is any Heusler alloy which has a tendency to undergo a tetragonal transition and at the same time possesses a high spin polarization at the Fermi level. From our study, it is found that out of the four materials, which exhibit a martensite phase as their ground state, three of these, namely, Ni$_{2}$MnGa, Ni$_{2}$MoGa and Co$_{2}$NbSn have a metallic nature; on the contrary, Co$_{2}$MoGa exhibits a high spin polarization.

description: We study the Goos-Hänchen shifts for Dirac fermions in graphene scattered by a triangular double barrier potential. The massless Dirac-like equation was used to describe the scattered fermions by such potential configuration. Our results show that the GHL shifts is affected by the geometrical structure of the double barrier. In particular the GHL shifts change sign at the transmission zero energies and exhibit enhanced peaks at each bound state associated with the double barrier when the incident angle is less than the critical angle associated with the total reflection.

description: We explore the recoverability of gas physical conditions with the Large Velocity Gradient (LVG) model, using the public code RADEX and the molecules HCN and CO. Examining a wide parameter range with a series of models of increasing complexity we use both grid and Monte Carlo Markov Chain (MCMC) methods to recover the input conditions, and quantify the inherent and noise induced uncertainties in the model results. We find that even with the benefit of generous assumptions the LVG models struggle to recover any parameter better than to within half a dex, although we find no evidence of systemic offsets. Examining isotopologue lines we demonstrate that it is always preferable to model the isotopologue abundance ratio as a free parameter, due to large biases introduced in all other parameters when an incorrect ratio is assumed. Finally, we explore the effects of the background radiation temperature on CO and HCN line ratios, with an emphasis on the effect of the CMB at $z>4$, and show that while the effect on the line ratios is minor, the effect on the SLED peak is significant and that the CO$(1-0)$ line luminosity to H$_2$ mass conversion factor ($α_{\rm CO}$) needs to be altered to account for the loss of contrast against the hotter CMB as redshift increases.

description: We present a comparative study of the glass forming ability of binary systems with varying composition, where the systems have similar global crystalline structure (CsCl+fcc). Biased Monte Carlo simulations using umbrella sampling technique shows that the free energy cost to create a CsCl nucleus increases as the composition of the smaller particles are decreased. We find that the systems with comparatively lower free energy cost to form CsCl nucleus exhibit more pronounced pre-crystalline demixing near the liquid/crystal interface. The structural frustration between the CsCl and fcc crystal demands this demixing. We show that closer to the equimolar mixture the entropic penalty for demixing is lower and a glass forming system may crystallize spontaneously when seeded with a nucleus. This entropic penalty as a function of composition shows a non-monotonic behavior with a maximum at a composition similar to the well known Kob-Anderson (KA) model. Although the KA model shows the maximum entropic penalty and thus maximum frustration against CsCl formation, it also shows a strong tendency towards crystallization into fcc lattice of the larger "A" particles which can be explained from the study of the energetics. Thus for systems closer to the equimolar mixture although it is the requirement of demixing which provides their stability against crystallization, for KA model it is not demixing but slow dynamics and structural frustration caused by the locally favored structure around the smaller "B" particles which make it a good glass former. Although the glass forming binary systems studied here are quite similar, differing only in composition, we find that their glass forming ability cannot be attributed to a single phenomena.

title: Conservation genetics for the critically endangered Great Green Macaw

description: Ex-situ and captive breeding populations are important strategies for endangered species conservation, and the role of genetics is increasingly being recognized in their management. Furthermore, patterns of genetic variation and structure can provide managers with information to support conservation strategies. Molecular markers can be used to assess the status of captive populations, help prevent biodiversity loss and inbreeding and understand genetic diversity in wild and captive populations. We used newly developed microsatellite markers to examine genetic structure and diversity in 4 captive populations and one wild population of the critically endangered Great Green Macaw. We did not find significant differences in expected and observed heterozygosity and allelic richness between all the populations evaluated and found the value for expected heterozygosity in all of them within the range of other macaw and parrot species evaluated. We found genetic structure when we evaluated the five populations together which largely corresponded to three clusters formed by Costa Rican, European and Colombian samples, and found further fine genetic structure when we evaluated Costa Rican samples and the European samples independently. Additionally, we used the microsatellite marker set to determine relatedness between founders of one of the captive breeding populations and to evaluate the relatedness and genetic diversity in the Costa Rican captive and release populations. Our results contribute to the understanding of the genetic diversity of the species, and they can be used to galvanize the management of captive breeding and release populations.

description: We review recent interest in the relativistic Riemann problem as a method for generating a non-equilibrium steady state. In the version of the problem under con- sideration, the initial conditions consist of a planar interface between two halves of a system held at different temperatures in a hydrodynamic regime. The new double shock solutions are in contrast with older solutions that involve one shock and one rarefaction wave. We use numerical simulations to show that the older solutions are preferred. Briefly we discuss the effects of a conserved charge. Finally, we discuss deforming the relativistic equations with a nonlinear term and how that deformation affects the temperature and velocity in the region connecting the asymptotic fluids.

description: L’environnement hydrique hospitalier a été décrit comme un réservoir potentiel d’entérobactéries productrices de carbapénèmase (EPC). Nous investiguons ici une épidémie d’EPC OXA-48 principalement à Citrobacter freundii dans un service d’hématologie d’un centre hospitalo-universitaire parisien. Entre janvier 2016 et juin 2019, 37 cas d’EPC OXA-48 (infections ou colonisations) ont été identifiés dans ce service. En octobre 2017, une unité dédiée a été créée pour prendre en charge les patients porteurs d’EPC. Malgré cette mesure, 11 cas ont été identifiés sans lien évident entre les cas, sauf pour un. Une investigation environnementale dans le service de juin à août 2018 a montré 7/74 toilettes et 1/39 siphons positifs à des EPC (7 C. freundii, 1 Enterobacter sakazakii et 1 Escherichia coli). Le séquençage à haut débit a montré une clonalité des souches de C. freundii OXA-48 de l’environnement et des patients. En plus des mesures de prévention usuelles, un nettoyage intensif (javel et détartrage) a été réalisé et toutes les toilettes ont été changées. Ces mesures ont permis de contenir l’épidémie. Cette étude suggère que les toilettes sont une source possible de transmission d’EPC.

description: It is demonstrated how an utilization of all existing experimental information on electric and magnetic nucleon form factors, to be described by the Unitary and Analytic (U\&A) nucleon electromagnetic structure model in space-like and time-like regions simultaneously, can provide numerical values of $f^F$, $f^D$, $f^S$ coupling constants in $SU(3)$ invariant interaction Lagrangian of the vector-meson nonet with $1/2^+$ octet baryons. The latter, together with universal vector-meson coupling constants $f_V$, play an essential role in a prediction of $1/2^+$ octet hyperon electromagnetic form factors behaviors.

description: We present a detailed study of the Flambaum-Ginges radiative potential method which enables the accurate inclusion of quantum electrodynamics (QED) radiative corrections in a simple manner in atoms, ions, and molecules over the range 10<=Z<=120, where Z is the nuclear charge. Calculations are performed for binding energy shifts to the lowest valence s, p, and d waves over the series of alkali atoms Na to E119. The high accuracy of the radiative potential method is demonstrated by comparison with rigorous QED calculations in frozen atomic potentials, with deviations on the level of 1%. The many-body effects of core relaxation and second- and higher-order perturbation theory on the interaction of the valence electron with the core are calculated. The inclusion of many-body effects tends to increase the size of the shifts, with the enhancement particularly significant for d waves; for K to E119, the self-energy shifts for d waves are only an order of magnitude smaller than the s-wave shifts. It is shown that account of many-body effects is essential for an accurate description of the Lamb shift.

description: Energy games belong to a class of turn-based two-player infinite-duration games}played on a weighted directed graph. It is one of the rare and intriguing combinatorial problems that lie in ${\sf NP} \cap {\sf co\mbox{-}NP}$, but are not known to be in ${\sf P}$. The existence of polynomial-time algorithms has been a major open problem for decades and apart from pseudopolynomial algorithms there is no algorithm that solves any non-trivial subclass in polynomial time. In this paper, we give several results based on the weight structures of the graph. First, we identify a notion of penalty and present a polynomial-time algorithm when the penalty is large. Our algorithm is the first polynomial-time algorithm on a large class of weighted graphs. It includes several worst-case instances on which previous algorithms, such as value iteration and random facet algorithms, require at least sub-exponential time. Our main technique is developing the first non-trivial approximation algorithm and showing how to convert it to an exact algorithm. Moreover, we show that in a practical case in verification where weights are clustered around a constant number of values, the energy game problem can be solved in polynomial time. We also show that the problem is still as hard as in general when the clique-width is bounded or the graph is strongly ergodic, suggesting that restricting the graph structure does not necessarily help.

description: The present article discusses the electrohydrodynamics of impacting non-Newtonian dielectric droplets on superhydrophobic (SH) surfaces. The role of important parameters like electric Eotvos number (Eoe), Weber number (We), dielectric particle concentration (TiO2) and polymer concentration (PEG-400) were elucidated in this experimental study. Due to the interplay of non-Newtonian effects and electric field, we had observed the suppression of drop rebound on SH surfaces at much lower Eoe compared to its Newtonian counterpart. It has been observed that with an increase in both polymer concentration or dielectric particle concentration, the suppression of drop rebounds was observed at lower Eoe. In order to encapsulate the combined effects of electric field and non-Newtonian dynamics on drop rebound suppression, we have introduced the ‘electro-elastic effect’. Contrary to the common observations of drop rebound on SH surfaces, this electro-elastic effect induces inhibition of drop rebound, thereby resulting in anti-superhydrophobicity. Subsequently, we also established a scaling relationship to show that the rebound suppression is observed as a manifestation of the onset of electro-elastic instability, when a proposed electric Weissenberg number (Wie) exceeds unity. Finally, we demarcated the rebound and rebound suppression regimes of droplet dynamics through a detailed phase map.

description: This papers addresses the connection between two classical models of phase transition phenomena describing different stages of the growth of clusters. The Becker-Döring model (BD) describes discrete-sized clusters through an infinite set of ordinary differential equations. The Lifshitz-Slyozov equation (LS) is a transport partial differential equation on the continuous half-line $x\in (0,+\infty)$. We introduce a scaling parameter $\varepsilon>0$, which accounts for the grid size of the state space in the BD model, and recover the LS model in the limit $\varepsilon\to 0$. The connection has been already proven in the context of outgoing characteristic at the boundary $x=0$ for the LS model, when small clusters tend to shrink. The main novelty of this work resides in a new estimate on the growth of small clusters, which behave at a fast time scale. Through a rigorous quasi steady state approximation, we derive boundary conditions for the incoming characteristic case, when small clusters tend to grow.
