description: Using resonant inelastic x-ray scattering (RIXS) at the Cu $L$-absorption edge, we have observed intense, dispersive spin excitations in highly overdoped Tl$_2$Ba$_2$CuO$_{6+δ}$ (superconducting $T_c =6$ K), a compound whose normal-state charge transport and thermodynamic properties have been studied extensively and shown to exhibit canonical Fermi-liquid behavior. Complementary RIXS experiments on slightly overdoped Tl$_2$Ba$_2$CuO$_{6+δ}$ ($T_c =89$ K) and on Y$_{1-x}$Ca$_{x}$Ba$_2$Cu$_3$O$_{6+δ}$ compounds spanning a wide range of doping levels indicate that these excitations exhibit energies and energy-integrated spectral weights closely similar to those of antiferromagnetic magnons in undoped cuprates. The surprising coexistence of Fermi-liquid-like charge excitations and high-energy spin excitations reminiscent of antiferromagnetic insulators in highly overdoped compounds poses a challenge to current theoretical models of the cuprates.
On the limits of Köhler activation theory: How do collision and coalescence affect the activation of aerosols?
Creators: name: Hoffmann, Fabian

subject: aerosol
subject: Dewey Decimal Classification::500 | Naturwissenschaften::550 | Geowissenschaften

description: Activation is necessary to form a cloud droplet from an aerosol, and it is widely accepted that it occurs as soon as a wetted aerosol grows beyond its critical radius. Traditional Köhler theory assumes that this growth is driven by the diffusion of water vapor. However, if the wetted aerosols are large enough, the coalescence of two or more particles is an additional process for accumulating sufficient water for activation. This transition from diffusional to collectional growth marks the limit of traditional Köhler theory and it is studied using a Lagrangian cloud model in which aerosols and cloud droplets are represented by individually simulated particles within large-eddy simulations of shallow cumuli. It is shown that the activation of aerosols larger than 0. 1μm in dry radius can be affected by collision and coalescence, and its contribution increases with a power-law relation toward larger radii and becomes the only process for the activation of aerosols larger than 0. 4-0. 8μm depending on aerosol concentration. Due to the natural scarcity of the affected aerosols, the amount of aerosols that are activated by collection is small, with a maximum of 1 in 10000 activations. The fraction increases as the aerosol concentration increases, but decreases again as the number of aerosols becomes too high and the particles too small to cause collections. Moreover, activation by collection is found to affect primarily aerosols that have been entrained above the cloud base.

description: We have imaged a freestanding graphene sheet of 210 nm in diameter with 2 Angstrom resolution by combining coherent diffraction and holography with low-energy electrons. The entire sheet is reconstructed from just a single diffraction pattern displaying the arrangement of 660.000 individual graphene unit cells at once. Given the fact that electrons with kinetic energies of the order of 100 eV do not damage biological molecules, it will now be a matter to develop methods for depositing individual proteins onto such graphene sheets.
Phase transitions of the striped domain-wall phases of S on Ru(0001)

description: Atomic sulfur chemisorbed on Ru(0001) forms a striped network of domain walls (DW's) at coverages above completion of a commensurate (3 × 3) R30°structure (θ>0.333). At high coverages (θ=0.48), this DW network transforms into a homogeneous commensurate c(2×4) structure with an ideal coverage θ=0.50. The temperature-induced phase transitions of the domain walls and the c(2×4) structures were investigated to low-energy electron diffraction spot profile analysis and compared to theoretical predictions. The phase transition of the superheavy walls, formed a low wall concentrations (coverages θ between 0.35 and 0.43), to the disordered lattice gas is found to be continuous, and compatible with a Kosterlitz-Thouless transition expected from theory. At higher coverages light DW's are formed (0.43<θ<0.48), which undergo a first-order transition, as evident from an intervening two-phase region formed by the DW phase and the incommensurate phase. Short-range order correlations are maintained in the disordered phase, which is best described by an incommensurate phase with strong disorder. Again a first-order transition is found for the commensurate c(2×4) structure, which also disorders into a short-range ordered incommensurate phase. Influences by finite-size effects are clearly visible. © 1995 The American Physical Society.
Can spicules be detected at disc centre in broad-band Ca II H filter imaging data ?

description: We estimate the formation height range contributing to broad-band and narrow-band filter imaging data in Ca II H to investigate whether spicules can be detected in such observations at the centre of the solar disc. We apply spectral filters of FWHMs from 0.03 nm to 1 nm to observed Ca line profiles to simulate Ca imaging data. We estimate the relative intensity contributions of off-limb and on-disc structures. We compare the synthetic Ca filter imaging data with intensity maps of Ca spectra at different wavelengths and temperature maps at different optical depths. We determine the intensity response function for the wavelengths covered by the filters of different FWHM. The intensity emitted off the solar limb is about 5% of the intensity at disc centre. For a 0.3 nm-wide Ca II H filter, up to about 1/3 of the off-limb intensity comes from emission in Hepsilon. On the disc, only about 15% of the intensity transmitted through a broad-band filter comes from the line-core region. No traces of elongated fibrillar structures are visible in imaging data at disc centre, opposite to the line-core images of the Ca spectra. The response function for a 0.3 nm-wide filter peaks at about 200 km. Relative contributions from atmospheric layers above 800 km are about 10%. The inversion results suggest that the slightly enhanced emission around the photospheric magnetic network in broad-band Ca imaging data is caused by a thermal canopy at a height of about 600 km. Broad-band Ca II H imaging data do not trace upper chromospheric structures such as spicules in observations at the solar disc because of the too small relative contribution of the line core to the total wavelength-integrated filter intensity.

description: Attosecond light pulses within the vacuum ultraviolet (VUV) energy range are predicted by solving the time-dependent Schrödinger equation (TDSE) for a model neon atom in short laser pulses of different field polarization states. We compare high-order harmonic generation in linearly polarized laser pulses to the method of polarization gating and find attosecond pulses that approach the Fourier limit of 700 as given by an indium filter, spectrally centered at 15 eV. At such low energies, harmonic generation has low sensitivity to ellipticity, which enables the generation of elliptically polarized attosecond pulses. We also show that emission at the atomic transition energies is strongly damped by including intensity averaging. © 2013 American Physical Society.
Traffic jams, gliders, and bands in the quest for collective motion

description: We study a simple swarming model on a two-dimensional lattice where the self-propelled particles exhibit a tendency to align ferromagnetically. Volume exclusion effects are present: particles can only hop to a neighboring node if the node is empty. Here we show that such effects lead to a surprisingly rich variety of self-organized spatial patterns. As particles exhibit an increasingly higher tendency to align to neighbors, they first self-segregate into disordered particle aggregates. Aggregates turn into traffic jams. Traffic jams evolve toward gliders, triangular high density regions that migrate in a well-defined direction. Maximum order is achieved by the formation of elongated high density regions - bands - that transverse the entire system. Numerical evidence suggests that below the percolation density the phase transition associated to orientational order is of first-order, while at full occupancy it is of second-order. The model highlights the (pattern formation) importance of a coupling between local density, orientation, and local speed.

description: We investigate the relationship between Hα and [OII](λ3727) emission in faint star-forming galaxies at z=1.47 with dust uncorrected star formation rates (SFRs) down to 1.4 Msun/yr, using data in two narrow-bands from WFCAM/UKIRT and Suprime-Cam/Subaru. A stacking analysis allows us to investigate Hα emission flux from bright [OII] emitters as well as faint ones for which Hα is not individually detected, and to compare them with a large sample of local galaxies. We find that there is a clear, positive correlation between the average Hα and [OII] luminosities for [OII] emitters at z=1.47, with its slope being consistent with the local relation. [OII] emitters at z=1.47 have lower mean observed ratios of Hα/[OII] suggesting a small but systematic offset (at 2.8σ significance) towards lower values of dust attenuation, A(Hα)~0.35, than local galaxies. This confirms that [OII] selection tends to pick up galaxies which are significantly less dusty on average than Hα selected ones, with the difference being higher at z=1.47 than at z=0. The discrepancy of the observed line ratios between [OII] emitters at z=1.47 and the local galaxies may in part be due to the samples having different metallicities. However, we demonstrate that metallicity is unlikely to be the main cause. Therefore, it is important to take into account that the relations for the dust correction which are derived using Hα emitter samples, and frequently used in many studies of high-z galaxies, may overestimate the intrinsic SFRs of [OII]-selected galaxies, and that surveys of [OII] emission galaxies are likely to miss dusty populations.

Publisher: name: Electronic Book Review
Year: 2018

description: In this essay, John Barber argues that sound suggests a new and valuable way of approaching and considering Arabic electronic literature. Based on the oral histories of Arab cultures, the use of sound in Arabic electronic literature provides a way of knowing and being in a literary world, real or imagined. Sound makes readers re-think their relational experiences with others, with themselves, and the spaces and places they inhabit. These shifting relationships promote interesting opportunities for Arabic electronic literature.

description: Achieving and maintaining the performance of ubiquitous (Automatic Speech Recognition) ASR system is a real challenge. The main objective of this work is to develop a method that will improve and show the consistency in performance of ubiquitous ASR system for real world noisy environment. An adaptive methodology has been developed to achieve an objective with the help of implementing followings, -Cleaning speech signal as much as possible while preserving originality / intangibility using various modified filters and enhancement techniques. -Extracting features from speech signals using various sizes of parameter. -Train the system for ubiquitous environment using multi-environmental adaptation training methods. -Optimize the word recognition rate with appropriate variable size of parameters using fuzzy technique. The consistency in performance is tested using standard noise databases as well as in real world environment. A good improvement is noticed. This work will be helpful to give discriminative training of ubiquitous ASR system for better Human Computer Interaction (HCI) using Speech User Interface (SUI).

Year: 2018

description: Les personnes en situation de handicap rencontrent de nombreuses difficultés d’accès aux soins. Leurs droits doivent être aussi mieux respectés et leur autonomie préservée. En raison de cette situation, la Haute Autorité de santé (HAS) a réalisé un guide articulé autour de deux principes et de cinq objectifs prioritaires, pour améliorer la prise en charge de ces personnes en établissement de santé. Le premier objectif est d’assurer la continuité de leurs parcours de santé en facilitant la transmission des informations entre les professionnels des différents secteurs, et entre professionnels et aidants. Le deuxième est de veiller à l’accessibilité des équipements, des services et de l’information au patient. Le troisième objectif insiste sur la présence de l’aidant. Son expertise particulière constitue une ressource pour les professionnels de santé et permet des soins de qualité. Le quatrième objectif consiste à améliorer les compétences des professionnels par le biais d’une sensibilisation, d’une formation, et d’une organisation interne le permettant. Enfin, le cinquième objectif est d’impulser une dynamique qualité en s’appuyant sur un travail en équipe, au moyen d’un pilotage pluriprofessionnel associant l’usager et soutenu par la direction. Cette dynamique, pour améliorer l’ensemble du parcours du patient, nécessite un décloisonnement des structures et pourra être valorisée dans le cadre de la certification des établissements de santé, à travers la méthode du patient traceur proposée dans le guide.

the Higher Attestation Commission and RISC journals to analyze the problem of chronic menstrual disorders caused
by the presence of psychogenic stress-dependent factors, associated with living conditions, and metabolic disorders, in particular, obesity and coronavirus infection. Unfavorable environmental factors influence the development
of neuroendocrine syndromes and menstrual disorders in women via changes in the psychogenic state, activation
of the sympathetic link of the autonomic nervous system, disorders of neuroendocrine regulation, and other mechanisms. This results in the development of metabolic disorders, menstrual disorders, and immunodeficiency, which

description: We report the observation and analysis of the $3\,^3Π_Ω$ double-minimum electronic excited state of $^{39}$K$^{85}$Rb. The spin-orbit components ($0^{+}, 0^{-}, 1$ and 2) of this state are investigated based on potentials developed from the available \emph{ab initio} potential curves. We have assigned the vibrational levels $v'=2-11$ of the $3\,^3Π_{1,2}$ potentials and $v'=2-12$ of the $3\,^3Π_{0^{+/-}}$ potential. We compare our experimental observations of the $3\,^3Π_Ω$ state with predictions based on theoretical potentials. The observations are based on resonance enhanced multiphoton ionization (REMPI) of ultracold KRb in vibrational levels $v"=14-25$ of the $a\,^3Σ^+$ state. These \emph{a}-state ultracold molecules are formed by photoassociation of ultracold $^{39}$K and $^{85}$Rb atoms to the 5(1) state of KRb followed by spontaneous emission to the \emph{a} state.

description: For any initial correlated network after any kind of attack where either nodes or edges are removed, we obtain general expressions for the degree-degree probability matrix and degree distribution. We show that the proposed analytical approach predicts the correct topological changes after the attack by comparing the evolution of the assortativity coefficient for different attack strategies and intensities in theory and simulations. We find that it is possible to turn an initial assortative network into a disassortative one, and vice versa, by fine-tuning removal of either nodes or edges. For an initial uncorrelated network, on the other hand, we discover that only a targeted edge-removal attack can induce such correlations.

description: A timely revaluation of Hugo Gernsback, the Luxembourgish-American tinkerer who regarded science fiction not merely as a literary form or fantastic escape, but also, according to Grant Wythoff, as a way for readers to interact with and reflect on media and (not least) to know where tools can be found to gather knowledge on their own. More of a community of tinkerers than a literary movement or social media network, Gernsback's early and amateurish engagements with technology can help us to gauge what is lost in the transition to corporatist black boxery.

Comprendre le point de vue des patients sur la sécurité des soins est quelque chose d’important, d’une part pour savoir quelles informations leur donner sur les mesures de sécurité des soins, et d’autre part pour définir les modalités de leur participation à des actions de sécurisation de ceux-ci. L’objectif de l’enquête qualitative rapportée vise à appréhender la manière dont les patients perçoivent la sécurité des soins au cours de leur hospitalisation en chirurgie. Méthode. Des entretiens ont été conduits auprès de patients hospitalisés dans cinq services de chirurgie digestive et endocrinienne et de chirurgie orthopédique. À partir d’une retranscription intégrale de 80 de ces entretiens, une analyse thématique fondée sur la théorie ancrée a été menée. Résultats. L’analyse de ces 80 entretiens montre que les indicateurs classiques de la sécurité des soins et leur sémantique, celle des événements indésirables, ne sont pas utilisés par les patients. Attentifs à des signes discrets, ces derniers évaluent leur sécurité en évaluant leurs interlocuteurs, notamment au cours de la consultation préopératoire et des échanges postopératoires. Conclusions. La confiance accordée par le patient, à l’origine de son sentiment de sécurité, est le produit agrégé d’éléments épars et subjectifs, tels que le style de communication du chirurgien, les compétences supposées des professionnels de santé, ou la capacité des équipes à fournir une information claire et de qualité.

description: Objectif. L’objectif est de mesurer, à l’aide de questionnaires appropriés, le niveau de satisfaction des patients en soins de longue durée et des résidents d’Ehpad, et de leurs familles, afin de faciliter la mise en place de mesures correctives ciblées sur leurs attentes. Méthode. Les questionnaires ont été élaborés au niveau régional par un groupe pluriprofessionnel, avec le soutien du réseau qualité des établissements de Bourgogne-Franche-Comté (Réqua). Une campagne régionale de mesure de la satisfaction a ensuite été proposée à tous les établissements concernés adhérents au Réqua. Résultats. Vingt-et-un établissements ont participé à la campagne 2017. Si les taux de satisfaction sont globalement élevés, certaines thématiques semblent porteuses d’amélioration : disponibilité et échanges avec le médecin, informations sur le conseil de vie sociale, accès aux espaces extérieurs, adaptation des repas aux goûts personnels, entretien du linge personnel. Les niveaux de satisfaction des patients-résidents et de leurs familles sont globalement relativement proches. La comparaison interétablissements montre une forte variabilité de ces niveaux. Conclusion. Il est nécessaire d’identifier les facteurs contribuant à une satisfaction élevée et de proposer des actions permettant d’agir sur ces facteurs. En outre, il est important de disposer d’outils complémentaires permettant de recueillir l’expression des patients-résidents dans ces structures, car un simple questionnaire de satisfaction semble inadapté dans plus de la moitié des cas.

description: In black hole thermodynamics of certain models, the thermodynamic first law may contain the pressure term. The corresponding entropy follows the area law whereas the thermodynamic energy is not the same with the black hole mass. If the pressure can be decomposed into two parts and recombined with the original thermodynamic quantities, then the thermodynamic energy becomes the black hole mass and the entropy satisfying the area law turns out to be the corrected entropy called the Wald entropy, respectively.

description: The Hubble Space Telescope (HST) Treasury Program on the Orion Nebula Cluster has used 104 orbits of HST time to image the Great Orion Nebula region with the Advanced Camera for Surveys (ACS), the Wide-Field/Planetary Camera 2 (WFPC2) and the Near Infrared Camera and Multi Object Spectrograph (NICMOS) instruments in 11 filters ranging from the U-band to the H-band equivalent of HST. The program has been intended to perform the definitive study of the stellar component of the ONC at visible wavelengths, addressing key questions like the cluster IMF, age spread, mass accretion, binarity and cirumstellar disk evolution. The scanning pattern allowed to cover a contiguous field of approximately 600 square arcminutes with both ACS and WFPC2, with a typical exposure time of approximately 11 minutes per ACS filter, corresponding to a point source depth AB(F435W) = 25.8 and AB(F775W)=25.2 with 0.2 magnitudes of photometric error. We describe the observations, data reduction and data products, including images, source catalogs and tools for quick look preview. In particular, we provide ACS photometry for 3399 stars, most of them detected at multiple epochs, WFPC2 photometry for 1643 stars, 1021 of them detected in the U-band, and NICMOS JH photometry for 2116 stars. We summarize the early science results that have been presented in a number of papers. The final set of images and the photometric catalogs are publicly available through the archive as High Level Science Products at the STScI Multimission Archive hosted by the Space Telescope Science Institute.

Ubiquitous nucleosome unwrapping in the yeast genome

description: Nucleosome core particle is a dynamic structure -- DNA may transiently peel off the histone octamer surface due to thermal fluctuations or the action of chromatin remodeling enzymes. Partial DNA unwrapping enables easier access of DNA-binding factors to their target sites and thus may provide a dominant pathway for effecting rapid and robust access to DNA packaged into chromatin. Indeed, a recent high-resolution map of distances between neighboring nucleosome dyads in \emph{S.cerevisiae} shows that at least 38.7\% of all nucleosomes are partially unwrapped. The extent of unwrapping follows a stereotypical pattern in the vicinity of genes, reminiscent of the canonical pattern of nucleosome occupancy in which nucleosomes are depleted over promoters and well-positioned over coding regions. To explain these observations, we developed a biophysical model which employs a 10-11 base pair periodic nucleosome energy profile. The profile, based on the pattern of histone-DNA contacts in nucleosome crystal structures and the idea of linker length discretization, accounts for both nucleosome unwrapping and higher-order chromatin structure. Our model reproduces the observed genome-wide distribution of inter-dyad distances, and accounts for patterns of nucleosome occupancy and unwrapping around coding regions. At the same time, our approach explains \emph{in vitro} measurements of accessibility of nucleosome-covered binding sites, and of nucleosome-induced cooperativity between DNA-binding factors. We are able to rule out several alternative scenarios of nucleosome unwrapping as inconsistent with the genomic data.

description: We propose an explicit-implicit scheme for numerically solving Special Relativistic Radiation Hydrodynamic (RRHD) equations, which ensures a conservation of total energy and momentum (matter and radiation). In our scheme, 0th and 1st moment equations of the radiation transfer equation are numerically solved without employing a flux-limited diffusion (FLD) approximation. For an hyperbolic term, of which the time scale is the light crossing time when the flow velocity is comparable to the speed of light, is explicitly solved using an approximate Riemann solver. Source terms describing an exchange of energy and momentum between the matter and the radiation via the gas-radiation interaction are implicitly integrated using an iteration method. The implicit scheme allows us to relax the Courant-Friedrichs-Lewy condition in optically thick media, where heating/cooling and scattering timescales could be much shorter than the dynamical timescale. We show that our numerical code can pass test problems of one- and two-dimensional radiation energy transport, and one-dimensional radiation hydrodynamics. Our newly developed scheme could be useful for a number of relativistic astrophysical problems. We also discuss how to extend our explicit-implicit scheme to the relativistic radiation magnetohydrodynamics.

description: We report the spontaneous generation of an Archimedean spiral pattern of fullerene via the evaporation of solvent. The self-organized spiral pattern exhibited equi-spacing on the order of micrometer between neighboring stripes. The characteristics of the spirals, such as the spacing between stripes, the number of stripes and the band width of stripes, could be controlled by tuning the thickness of the liquid bridge and the concentration of solution. The mechanism of pattern formation is interpreted in terms of a specific traveling wave on the liquid-solid interface accompanied by a stick-slip process of the contact line.

description: Without anonymous peer review, there can be no formal recognition of literary scholarship, and ebr is no exception. That said, our journal looks for occasions to turn our confidential reports into public riPOSTes, if the reviewer is so inclined. In this essay, our colleagues from Coimbra, Manuel Portela and Ana Marques da Silva, stage reflections on the peer reviews that their own scholarly work has generated, in earlier submissions to other peer review outlets. The "metapaper" that results, is a further step in the initiative not to do away with peer review, but to bring the process into the public sphere.
