description: A common issue in low temperature measurements of enhancement-mode metal-oxide-semiconductor (MOS) field-effect transistors (FETs) in the low electron density regime is the high contact resistance dominating the device impedance. In that case a voltage bias applied across the source and drain contact of a Hall bar MOSFET will mostly fall across the contacts (and not across the channel) and therefore magneto-transport measurements become challenging. However, from a physical point of view, the study of MOSFET nanostructures in the low electron density regime is very interesting (impurity limited mobility [1], carrier interactions [2,3] and spin-dependent transport [4]) and it is therefore important to come up with solutions [5,6] that work around the problem of a high contact resistance in such devices (c.f. Fig. 1 (a)).

description: We carry out a comprehensive smooth particle hydrodynamics simulation survey of double-degenerate white dwarf binary mergers of varying mass combinations in order to establish correspondence between initial conditions and remnant configurations. We find that all but one of our simulation remnants share general properties such as a cold, degenerate core surrounded by a hot disk, while our least massive pair of stars forms only a hot disk. We characterize our remnant configurations by the core mass, the rotational velocity of the core, and the half-mass radius of the disk. We also find that some of our simulations with very massive constituent stars exhibit helium detonations on the surface of the primary star before complete disruption of the secondary. However, these helium detonations are insufficiently energetic to ignite carbon, and so do not lead to prompt carbon detonations.

description: (Abridged) Since its launch in October 2002, the INTEGRAL satellite has revolutionized our knowledge of the hard X-ray sky thanks to its unprecedented imaging capabilities and source detection positional accuracy above 20 keV. Nevertheless, many of the newly-detected sources in the INTEGRAL sky surveys are of unknown nature. The combined use of available information at longer wavelengths (mainly soft X-rays and radio) and of optical spectroscopy on the putative counterparts of these new hard X-ray objects allows us to pinpoint their exact nature. Continuing our long-standing program that has been running since 2004, and using 6 different telescopes of various sizes, we report the classification through optical spectroscopy of 22 more unidentified or poorly studied high-energy sources detected with the IBIS instrument onboard INTEGRAL. We found that 16 of them are active galactic nuclei (AGNs), while the remaining 6 objects are within our Galaxy. Among the identified extragalactic sources, 14 are Type 1 AGNs; of these, 6 lie at redshift larger than 0.5 and one has z = 3.12, which makes it the second farthest object detected in the INTEGRAL surveys up to now. The remaining AGNs are of type 2, and one of them is a pair of interacting Seyfert 2 galaxies. The Galactic objects are identified as two cataclysmic variables, one high-mass X-ray binary, one symbiotic binary and two chromospherically active stars. We thus still find that AGNs are the most abundant population among hard X-ray objects identified through optical spectroscopy. Moreover, we note that the higher sensitivity of the more recent INTEGRAL surveys is now enabling the detection of high-redshift AGNs, thus allowing the exploration of the most distant hard X-ray emitting sources and possibly of the most extreme blazars.

The key tool in the proof of our main result is the Mittag-Leffler expansion for Bessel functions of the first kind and the fact that, according to Ismail and Muldoon [IM2], the smallest positive zeros of some Dini functions are less than the first positive zero of the Bessel function of the first kind.

description: Topological insulators are insulating in the bulk but possess spin-momentum locked metallic surface states protected by time-reversal symmetry. The existence of these surface states has been confirmed by angle-resolved photoemission spectroscopy (ARPES) and scanning tunneling microscopy (STM). Detecting these surface states by transport measurement, which might at first appear to be the most direct avenue, was shown to be much more challenging than expected. Here, we report a detailed electronic transport study in high quality Bi2Se3 topological insulator thin films. Measurements under in-plane magnetic field, along and perpendicular to the bias current show opposite magnetoresistance. We argue that this contrasting behavior is related to the locking of the spin and current direction providing evidence for helical spin structure of the topological surface states.

description: The force-assisted desorption kinetics of a macromolecule from adhesive surface is studied theoretically, using the notion of tensile (Pincus) blobs, as well as by means of Monte-Carlo (MC) and Molecular Dynamics (MD) simulations. We show that the change of detached monomers with time is governed by a differential equation which is equivalent to the nonlinear porous medium equation (PME), employed widely in transport modeling of hydrogeological systems. Depending on the pulling force and the strength of adsorption, three kinetic regimes can be distinguished: (i) "trumpet" (weak adsorption and small pulling force), (ii) "stem-trumpet" (weak adsorption and moderate force), and (iii) "stem" (strong adsorption and large force). Interestingly, in all regimes the number of desorbed beads $M(t)$, and the height of the first monomer (which experiences a pulling force) $R(t)$ above the surface follow an universal square-root-of-time law. Consequently, the total time of detachment $$, scales with polymer length $N$ as $ \propto N^2$. Our main theoretical conclusions are tested and found in agreement with data from extensive MC- and MD-simulations.

description: We present and analyse optical and ultra-violet colours for passive and optically-red Coma cluster galaxies for which we have spectroscopic age and element abundance estimates. Our sample of 150 objects covers a wide range in mass, from giant ellipticals to the bright end of the dwarf-galaxy regime. We focus on the colours FUV-i, NUV-i, FUV-NUV, u*-g and g-i. We find that all of these colours are correlated with both luminosity and velocity dispersion at the >5 sigma level, with FUV-i and FUV-NUV becoming bluer with increasing `mass' while the other colours become redder. We perform an empirical analysis to assess what fraction of the variation in each colour can be accounted for by variations in the average stellar populations, as traced by the optical spectra. For u*-g and g-i, most of the observed scatter (~80% after allowing for measurement errors and for systematic errors in u*-g) is attributable to stellar population variations, with colours becoming redder with increasing age and metallicity (Mg/H). The FUV-i colour becomes bluer with increasing age and with increasing Mg/H, favouring a `metal-rich single-star' origin for the UV upturn. However, correlations with the optically-dominant stellar populations account for only about half of the large observed scatter. We propose that the excess scatter in FUV-i may be due to a varying proportion of ancient stars in galaxies with younger average ages. The NUV-i colour is sensitive to age and Mg/H, but exhibits excess scatter that can be attributed to `leakage' of the FUV upturn. Applying a correction based on the FUV-i colour we account for ~80% of the variance in NUV-i, as for the optical colours. The FUV-NUV colour shows strong correlations with age and Mg/H, and little residual scatter. Interpreting this colour is complicated however, since it mixes the effects from the main-sequence turn-off with those from the hot evolved stars.

description: The reader can find in the literature a lot of different techniques to study the dynamics of a given system and also, many suitable numerical integrators to compute them. Notwithstanding the recent work of Maffione et al. (2011a) for mappings, a detailed comparison among the widespread indicators of chaos in a general system is still lacking. Such a comparison could lead to select the most efficient algorithms given a certain dynamical problem. Furthermore, in order to choose the appropriate numerical integrators to compute them, more comparative studies among numerical integrators are also needed. This work deals with both problems. We first extend the work of Maffione et al. (2011) for mappings to the 2D Hénon & Heiles (1964) potential, and compare several variational indicators of chaos: the Lyapunov Indicator (LI); the Mean Exponential Growth Factor of Nearby Orbits (MEGNO); the Smaller Alignment Index (SALI) and its generalized version, the Generalized Alignment Index (GALI); the Fast Lyapunov Indicator (FLI) and its variant, the Orthogonal Fast Lyapunov Indicator (OFLI); the Spectral Distance (D) and the Dynamical Spectras of Stretching Numbers (SSNs). We also include in the record the Relative Lyapunov Indicator (RLI), which is not a variational indicator as the others. Then, we test a numerical technique to integrate Ordinary Differential Equations (ODEs) based on the Taylor method implemented by Jorba & Zou (2005) (called taylor), and we compare its performance with other two well-known efficient integrators: the Prince & Dormand (1981) implementation of a Runge-Kutta of order 7-8 (DOPRI8) and a Bulirsch-Stöer implementation. These tests are run under two very different systems from the complexity of their equations point of view: a triaxial galactic potential model and a perturbed 3D quartic oscillator.

A phenomenological model for the X-ray spectrum of Nova V2491 Cygni

description: The X-ray flux of Nova V2491 Cyg reached a maximum some forty days after optical maximum. The X-ray spectrum at that time, obtained with the RGS of XMM-Newton, shows deep, blue-shifted absorption by ions of a wide range of ionization. We show that the deep absorption lines of the X-ray spectrum at maximum, and nine days later, are well described by the following phenomenological model with emission from a central blackbody and from a collisionally ionized plasma (CIE). The blackbody spectrum (BB) is absorbed by three main highly-ionized expanding shells; the CIE and BB are absorbed by cold circumstellar and interstellar matter that includes dust. The outflow density does not decrease monotonically with distance. The abundances of the shells indicate that they were ejected from an O-Ne white dwarf. We show that the variations on time scales of hours in the X-ray spectrum are caused by a combination of variation in the central source and in the column density of the ionized shells. Our phenomenological model gives the best description so far of the supersoft X-ray spectrum of nova V2491 Cyg, but underpredicts, by a large factor, the optical and ultraviolet flux. The X-ray part of the spectrum must originate from a very different layer in the expanding envelope, presumably much closer to the white dwarf than the layers responsible for the optical/ultraviolet spectrum. This is confirmed by absence of any correlation between the X-ray and UV/optical observed fluxes.

Les ambiguïtés sociales du progressisme pédagogique de John Dewey

description: Nombreux sont les chercheurs qui inclinent aujourd’hui à s’intéresser principalement aux dimensions démocratiques du progressisme pédagogique de John Dewey ainsi qu’à son actualité pour questionner les débats sur l’école en France. La notion de progressisme pédagogique, particulièrement sous sa forme deweyenne, est ainsi souvent pensée et présentée comme étroitement solidaire, sinon consubstantielle, d’un processus de démocratisation en matière sociale. Le présent article vise à interroger cette interprétation en mettant en lumière les ambiguïtés sociales du progressisme pédagogique deweyen au tournant des XIXe et XXe siècles aux États-Unis. En étudiant le rapport entre les choix politiques, philosophiques et éducatifs du philosophe, il montre qu’on ne peut pas considérer son progressisme pédagogique sans analyser, interroger et discuter les ambiguïtés sociales qu’il véhicule.

description: Given a limited number of entries from the superposition of a low-rank matrix plus the product of a known fat compression matrix times a sparse matrix, recovery of the low-rank and sparse components is a fundamental task subsuming compressed sensing, matrix completion, and principal components pursuit. This paper develops algorithms for distributed sparsity-regularized rank minimization over networks, when the nuclear- and $\ell_1$-norm are used as surrogates to the rank and nonzero entry counts of the sought matrices, respectively. While nuclear-norm minimization has well-documented merits when centralized processing is viable, non-separability of the singular-value sum challenges its distributed minimization. To overcome this limitation, an alternative characterization of the nuclear norm is adopted which leads to a separable, yet non-convex cost minimized via the alternating-direction method of multipliers. The novel distributed iterations entail reduced-complexity per-node tasks, and affordable message passing among single-hop neighbors. Interestingly, upon convergence the distributed (non-convex) estimator provably attains the global optimum of its centralized counterpart, regardless of initialization. Several application domains are outlined to highlight the generality and impact of the proposed framework. These include unveiling traffic anomalies in backbone networks, predicting networkwide path latencies, and mapping the RF ambiance using wireless cognitive radios. Simulations with synthetic and real network data corroborate the convergence of the novel distributed algorithm, and its centralized performance guarantees.

Forschungsunterstützung

description: Die Einrichtung institutioneller Open-Access-Publikationsplattformen war ein erster Anlass, Beratungsangebote zum Thema Publizieren an Bibliotheken zu entwickeln, und Ausgangspunkt einer darüber hinausgehenden, allgemeinen Publikationsberatung. Diese Erweiterung des Themenfeldes bringt zugleich neue Herausforderungen für die Berater:innen, etwa hinsichtlich der eigenen Kompetenzentwicklung oder des Identifizierens relevanter Themen und deren Aufbereitung für die Beratungspraxis.

So gilt es derzeit unter anderem Wissen zu folgenden Themen aufzubauen:

die Veränderungen in der Forschungsbewertung mit der Ausweitung der Publikationstypen und stärkerer Berücksichtigung von Open-Science-Praktiken,

die Verwendung von künstlicher Intelligenz im wissenschaftlichen Schreiben und Publizieren im Spannungsfeld von Urheberrecht, guter wissenschaftlicher Praxis, Richtlinien von Zeitschriften sowie Akteuren mit betrügerischen Absichten.

Der Workshop möchte exemplarisch an diesen beiden Themen mit den Teilnehmer:innen diskutieren, welche Rolle die Publikationsberatung als Element der Forschungsunterstützung spielen kann und welche Angebote und Kompetenzen dafür entwickelt werden sollten. Nach zwei kurzen Impulsvorträgen (jeweils max. 10 Minuten) soll im Anschluss unter Verwendung interaktiver Tools wie Mentimeter diskutiert werden:

Zu welchen Aspekten kann bei den genannten Themen beraten werden?

Welche Kenntnisse und Fähigkeiten müssen die Berater:innen erwerben, um entsprechend beraten zu können?

Auf welche Materialien kann zurückgegriffen werden, welche sind noch zu entwickeln?

Welche weiteren Themen zeichnen sich ab, zu denen die Publikationsberatung künftig ebenfalls gefragt ist?

Der Workshop hat zum Ziel, den Austausch und die Vernetzung unter Publikationsberater:innen zu fördern. Die in der Diskussion identifizierten Punkte sollen als Ausgangspunkt für weitere Austauschaktivitäten dienen, die im Anschluss an die Open-Access-Tage 2024 organisiert werden. Während es für “etablierte” Themen wie Forschungsdatenmanagement, Zweitveröffentlichungsservices oder Informationsbudget bereits Austauschmöglichkeiten gibt, soll hier idealerweise eine Lücke geschlossen werden. Wir freuen uns darauf, mit den Teilnehmer:innen in Austausch zu treten und gemeinsame Ideen und Formate für zukünftige Aktivitäten zu entwickeln.

description: We report the discovery of a substellar companion to the nearby solar-type star HD 46588 (F7V, 17.9 pc, ~3 Gyr). HD 46588 B was found through a survey for common proper motion companions to nearby stars using data from the Wide-field Infrared Survey Explorer and the Two-Micron All-Sky Survey. It has an angular separation of 79.2" from its primary, which corresponds to a projected physical separation of 1420 AU. We have measured a spectral type of L9 for this object based on near-infrared spectroscopy performed with TripleSpec at Palomar Observatory. We estimate a mass of 0.064+0.008/-0.019 Msun from a comparison of its luminosity to the values predicted by theoretical evolutionary models for the age of the primary. Because of its companionship to a well-studied star, HD 46588 B is one of the few known brown dwarfs at the L/T transition for which both age and distance estimates are available. Thus, it offers new constraints on the properties of brown dwarfs during this brief evolutionary phase. The discovery of HD 46588 B also illustrates the value of the Wide-field Infrared Survey Explorer for identifying brown dwarfs in the solar neighborhood via their proper motions.

description: We present neutrino mass bounds using 900,000 luminous galaxies with photometric redshifts measured from Sloan Digital Sky Survey III Data Release Eight (SDSS DR8). The galaxies have photometric redshifts between $z = 0.45$ and $z = 0.65$, and cover 10,000 square degrees and thus probe a volume of 3$h^{-3}$Gpc$^3$, enabling tight constraints to be derived on the amount of dark matter in the form of massive neutrinos. A new bound on the sum of neutrino masses $\sum m_ν< 0.26$ eV, at 95% confidence level (CL), is obtained after combining our sample of galaxies, which we call "CMASS", with WMAP 7 year Cosmic Microwave Background (CMB) data and the most recent measurement of the Hubble parameter from the Hubble Space Telescope (HST). This constraint is obtained with a conservative multipole range choice of $30 < \ell < 200$ in order to minimize non-linearities, and a free bias parameter in each of the four redshift bins. We study the impact of assuming this linear galaxy bias model using mock catalogs, and find that this model causes a small ($\sim 1-1.5 σ$) bias in $Ω_{\rm DM} h^2$. For this reason, we also quote neutrino bounds based on a conservative galaxy bias model containing additional, shot noise-like free parameters. In this conservative case, the bounds are significantly weakened, e.g. $\sum m_ν< 0.36$ eV (95% confidence level) for WMAP+HST+CMASS ($\ell_{\rm max}=200$). We also study the dependence of the neutrino bound on multipole range ($\ell_{\rm max}=150$ vs $\ell_{\rm max}=200$) and on which combination of data sets is included as a prior. The addition of supernova and/or Baryon Acoustic Oscillation data does not significantly improve the neutrino mass bound once the HST prior is included. [abridged]

description: Following a previous calculation of quark scattering in eikonal approximation, this paper presents a new, analytic and rigorous approach to the calculation of QCD phenomena. In this formulation a basic distinction between the conventional "idealistic" description of QCD and a more "realistic" description is brought into focus by a non-perturbative, gauge-invariant evaluation of the Schwinger solution for the QCD generating functional in terms of the exact Fradkin representations of the Green's functional and the vacuum functional. Because quarks exist asymptotically only in bound states, their transverse coordinates can never be measured with arbitrary precision; the non-perturbative neglect of this statement leads to obstructions that are easily corrected by invoking in the basic Lagrangian a probability amplitude which describes such transverse imprecision. The second result of this non-perturbative analysis is the appearance of a new and simplifying output called "Effective Locality", in which the interactions between quarks by the exchange of a "gluon bundle" - which "bundle" contains an infinite number of gluons, including cubic and quartic gluon interactions - display an exact locality property that reduces the several functional integrals of the formulation down to a set of ordinary integrals. It should be emphasized that "non-perturbative" here refers to the effective summation of all gluons between a pair of quark lines, but does not (yet) include a summation over all closed-quark loops which are tied by gluon-bundle exchange to the rest of the "Bundle Diagram". As an example of the power of these methods we offer as a first analytic calculation the quark-antiquark binding potential of a pion, and the corresponding three-quark binding potential of a nucleon, obtained in a simple way from relevant eikonal scattering approximations.

description: Recent experimental and theoretical studies have highlighted the possible role of a electronic nematic liquid in underdoped cuprate superconductors. We calculate, within a model of d-wave superconductor with Hubbard correlations, the spin susceptibility in the case of a small explicitly broken rotational symmetry of the underlying lattice. We then exhibit how the induced spin response asymmetry is strongly enhanced by correlations as one approaches the instability to stripe order. In the disorder-induced stripe phase, impurities become spin nematogens with a C_2 symmetric impurity resonance state, and the disorder-averaged spin susceptibility remains only C_2 symmetric at low energies, similar to recent data from neutron scattering experiments on underdoped YBCO.

Or, ce conservatisme scolaire a pu parfois s’énoncer du point de vue d’un idéal politique de gauche. Comment comprendre cette apparente contradiction. L’article explore deux hypothèses. La première est ordonnée à l’idée «d’émancipation», héritée des Lumières et notamment de Condorcet: l’école, pour accomplir sa mission émancipatrice, ne doit pas renoncer à la culture qu’elle transmet. La seconde hypothèse est plus «marxisante»: le «pédagogisme», en renonçant à une école culturellement exigeante, affaiblit l’esprit critique et est au service d’un capitalisme mondialisé.

description: We have mapped 20 molecular lines in the Central Molecular Zone (CMZ) around the Galactic Centre, emitting from 85.3 to 93.3 GHz. This work used the 22-m Mopra radio telescope in Australia, equipped with the 8-GHz bandwidth UNSW-MOPS digital filter bank, obtaining \sim 2 km/s spectral and \sim 40 arcsec spatial resolution. The lines measured include emission from the c-C3H2, CH3CCH, HOCO+, SO, H13CN, H13CO+, SO, H13NC, C2H, HNCO, HCN, HCO+, HNC, HC3N, 13CS and N2H+ molecules. The area covered is Galactic longitude -0.7 to 1.8 deg. and latitude -0.3 to 0.2 deg., including the bright dust cores around Sgr A, Sgr B2, Sgr C and G1.6-0.025. We present images from this study and conduct a principal component analysis on the integrated emission from the brightest 8 lines. This is dominated by the first component, showing that the large-scale distribution of all molecules are very similar. We examine the line ratios and optical depths in selected apertures around the bright dust cores, as well as for the complete mapped region of the CMZ. We highlight the behaviour of the bright HCN, HNC and HCO+ line emission, together with that from the 13C isotopologues of these species, and compare the behaviour with that found in extra-galactic sources where the emission is unresolved spatially. We also find that the isotopologue line ratios (e.g. HCO+/H13CO+) rise significantly with increasing red-shifted velocity in some locations. Line luminosities are also calculated and compared to that of CO, as well as to line luminosities determined for external galaxies.

Le Nouvel humanisme: une critique du progressisme éducatif
Creators: name: Ottavi, Dominique
Publisher: name: Revista Lusófona de Educação
Year: 2019

description: Le Nouvel humanisme est un mouvement de critique littéraire déployé du début du XXe siècle à la deuxième Guerre mondiale, qui a de nombreuses implications pour l’éducation. Nous abordons deux de ses principales figures, Irving Babbitt (1865-1933), et Norman Foerster (1887-1972) pour exposer ces enjeux. Pour les Nouveaux humanistes, l’enseignement des grandes oeuvres a une portée morale et politique et ne doit donc pas être réservé aux spécialistes de la littérature ou de la philosophie. Cette étude doit être largement proposée, notamment au niveau de l’enseignement secondaire, dans une école démocratique. Pour cette raison l’éducation progressive est la cible de la critique, en tant qu’aspect d’une civilisation qui s’est dévoyée à partir de la modernité. Les progrès scientifiques ont engendré une puissance qui n’est pas accompagnée de sagesse, tandis que la réaction romantique au bouleversement de la culture par l’exploration de la nature a engendré un sentimentalisme stérile. C’est dans cette perspective que les oeuvres doivent être analysées et transmises. Norman Foerster a composé et appliqué un programme pour l’université d’Iowa qui donne une idée concrète de l’enseignement des Nouveaux humanistes. Devrait-on s’en inspirer pour former les sujets contemporains, manquant de repères dans le désordre du XXIe siècle ?

description: A woman tells a story about a man who likes to dress as a woman. The chief in the story is attracted to this man, and not knowing that he is actually a woman, pays his/her dowry. When the hare tells him that his bride to be is actually a man, the chief organizes a festival where everyone takes their clothes off. In the meantime, a female frog agrees to exchange her sex with that of the cross-dressing man. On the festival, the man appears to have a vagina. The frog, however, turns out to have been pregnant, and dies since she cannot give birth.
Conservatisme social et réformisme pédagogique? Un syndicat d’enseignants français après Mai 1968: la CNGA
Creators: name: Verneuil, Yves
Publisher: name: Revista Lusófona de Educação
Year: 2019

description: À la veille de Mai 1968, on peut observer une concordance entre le positionnement pédagogique et le positionnement idéologique des syndicats enseignants français: les syndicats progressistes du point de vue politique sont - avec des nuances - également progressistes du point de vue pédagogique, et les syndicats idéologiquement conservateurs sont également conservateurs du point de vue pédagogique. La naissance de la CNGA, en juin 1968, semble remettre ce schéma en cause. En effet, ce syndicat, qui obtient un score honorable aux élections professionnelles de 1969, se présente comme “libéral” et hostile aux syndicats de gauche, qu’il voit comme “totalitaires”; mais en même temps il insiste sur son réformisme en matière pédagogique. L’analyse de ses positions conduit toutefois à rappeler la distinction entre réformisme et progressisme. Par ailleurs, la CNGA condamne toutes les réformes décidées par le ministère après Mai-juin 1968. L’ambiguïté de son positionnement explique son rapide déclin dès les années 1970.

description: We report on a systematic study of the temperature-dependent Hall coefficient and thermoelectric power in ultra-thin metallic LaNiO$_3$ films that reveal a strain-induced, self-doping carrier transition that is inaccessible in the bulk. As the film strain varies from compressive to tensile at fixed composition and stoichiometry, the transport coefficients evolve in a manner strikingly similar to those of bulk hole-doped superconducting cuprates with varying doping level. Density functional calculations reveal that the strain-induced changes in the transport properties are due to self-doping in the low-energy electronic band structure. The results imply that thin-film epitaxy can serve as a new means to achieve hole-doping in other (negative) charge-transfer gap transition metal oxides without resorting to chemical substitution.
Impulsive acceleration of coronal mass ejections: II. Relation to SXR flares and filament eruptions

description: Using high time cadence images from the STEREO EUVI, COR1 and COR2 instruments, we derived detailed kinematics of the main acceleration stage for a sample of 95 CMEs in comparison with associated flares and filament eruptions. We found that CMEs associated with flares reveal on average significantly higher peak accelerations and lower acceleration phase durations, initiation heights and heights, at which they reach their peak velocities and peak accelerations. This means that CMEs that are associated with flares are characterized by higher and more impulsive accelerations and originate from lower in the corona where the magnetic field is stronger. For CMEs that are associated with filament eruptions we found only for the CME peak acceleration significantly lower values than for events which were not associated with filament eruptions. The flare rise time was found to be positively correlated with the CME acceleration duration, and negatively correlated with the CME peak acceleration. For the majority of the events the CME acceleration starts before the flare onset (for 75% of the events) and the CME accleration ends after the SXR peak time (for 77% of the events). In ~60% of the events, the time difference between the peak time of the flare SXR flux derivative and the peak time of the CME acceleration is smaller than \pm5 min, which hints at a feedback relationship between the CME acceleration and the energy release in the associated flare due to magnetic reconnection.

description: The interstellar and intra-cluster medium in giant elliptical galaxies and clusters of galaxies is often assumed to be in hydrostatic equilibrium. Numerical simulations, however, show that about 5-30% of the pressure in a cluster is provided by turbulence induced by, for example, the central AGN and merger activity. We aim to put constraints on the turbulent velocities and turbulent pressure in the ICM of the giant elliptical galaxies NGC 5044 and NGC 5813 using XMM-Newton RGS observations. The magnitude of the turbulence is estimated using the Fe XVII lines at 15.01 A, 17.05 A, and 17.10 A in the RGS spectra. At low turbulent velocities, the gas becomes optically thick in the 15.01 A line due to resonant scattering, while the 17 A lines remain optically thin. By comparing the (I(17.05)+I(17.10))/I(15.01) line ratio from RGS with simulated line ratios for different Mach numbers, the level of turbulence is constrained. The measurement is limited by systematic uncertainties in the atomic data, which are at the 20-30% level. We find that the line ratio in NGC 5813 is significantly higher than in NGC 5044. This difference can be explained by a higher level of turbulence in NGC 5044. The high turbulent velocities and the fraction of the turbulent pressure support of >40% in NGC 5044, assuming isotropic turbulence, confirm that it is a highly disturbed system, probably due to an off-axis merger. The turbulent pressure support in NGC 5813 is more modest at 15-45%. The (I(17.05)+I(17.10))/I(15.01) line ratio in an optically thin plasma, calculated using AtomDB v2.0.1, is 2 sigma above the ratio measured in NGC 5044, which cannot be explained by resonant scattering. This shows that the discrepancies between theoretical, laboratory, and astrophysical data on Fe XVII lines need to be reduced to improve the accuracy of the determination of turbulent velocities using resonant scattering.

description: Graphene with high carrier mobility μ is required both for graphene-based electronic devices and for the investigation of the fundamental properties of graphene's Dirac fermions. It is largely accepted that the mobility-limiting factor in graphene is the Coulomb scattering off of charged impurities that reside either on graphene or in the underlying substrate. This is true both for traditional graphene devices on SiO2 substrates and possibly for the recently reported high-mobility suspended and supported devices. An attractive approach to reduce such scattering is to place graphene in an environment with high static dielectric constant κ that would effectively screen the electric field due to the impurities. However, experiments so far report only a modest effect of high-κ environment on mobility. Here, we investigate the effect of the dielectric environment of graphene by studying electrical transport in multi-terminal graphene devices that are suspended in liquids with κ ranging from 1.9 to 33. For non-polar liquids (κ<5) we observe a rapid increase of μ with κ and report a record room-temperature mobility as large as ~60,000 cm2/Vs for graphene devices in anisole (κ=4.3), while in polar liquids (κ>18) we observe a drastic drop in mobility. We demonstrate that non-polar liquids enhance mobility by screening charged impurities adsorbed on graphene, while charged ions in polar liquids cause the observed mobility suppression. Furthermore, using molecular dynamics simulation we establish that scattering by out-of-plane flexural phonons, a dominant scattering mechanism in suspended graphene in vacuum at room temperature, is suppressed by the presence of liquids. We expect that our findings may provide avenues to control and reduce carrier scattering in future graphene-based electronic devices.
