description: We examine the effect of inhomogeneous broadening on the collective response of a planar metamaterial consisting of asymmetric split ring resonators. We show that such a response leads to a transmission resonance that can persist when the broadening of individual meta-atom resonance frequencies is roughly one half the frequency characterizing the split ring asymmetry. We also find that larger degrees of inhomogeneous broadening can drastically alter the cooperative response, destroying this resonance. The reduced effect of cooperative response due to inhomogeneous broadening may find applications in producing metamaterial samples that more closely mimic homogeneous magneto-dielectric medium with well-defined susceptibility and permittivity.

description: In examining affective motivations and meanings associated with kin-based tattooing, this article proposes a practice of ‘s/kinship’: the tangible inscription of relational personhood on the body. While research on the practice of Western tattooing has long been drawn into discourses of deviance and individual identity, little attention has been paid to the tattooing of social relations. Drawing on surveys and interview data, this article highlights the significance of kinship and other forms of relationality in tattooing, bringing attention to how these are manifested through the skin as expressions of social proximity, permanence, and porosity. In doing so an analytic approach to s/kinship is developed to foreground the practice of tattooing as an expression of relational personhood, one that highlights the permeability of personhood as a salient ontological feature in the social life of tattoos and the tattooed.

description: We study bright solitons in a Bose-Einstein condensate with a spin-orbit coupling that has been realized experimentally. Both stationary bright solitons and moving bright solitons are found. The stationary bright solitons are the ground states and possess well-defined spin-parity, a symmetry involving both spatial and spin degrees of freedom; these solitons are real valued but not positive definite, and the number of their nodes depends on the strength of spin-orbit coupling. For the moving bright solitons, their shapes are found to change with velocity due to the lack of Galilean invariance in the system.

description: Among plasma metabolites linked with a health-conscious food pattern (HCFP) identified in the Malmö Diet and Cancer epidemiological study, circulating ergothioneine (ERT) concentrations exhibited the strongest independent association with reduced risk of cardiometabolic disease and all-cause mortality and were also related to alcohol consumption. Thus, we first assessed whether alcohol intake and ERT were similarly associated in participants of the Hunter Community Study (HCS) that did not follow an HCFP-based diet. Then, we sought to identify the presence of associations with some biomarkers associated with cardiovascular disease. In a multivariable adjusted, robust regression analysis, compared to non-drinkers, safe drinkers had, on average, a serum ERT concentration 0.112 (95% CI: 0.0–0.225; P = 0.051) units higher and moderate-hazardous drinkers had a serum ERT concentration 0.240 (95% CI: 0.093–0.387; P = 0.001) units higher. Moreover, stepwise multiple linear regression shows that age (P = 0.025), and asymmetric dimethyl-L-arginine (ADMA) (P = 0.001) were independently associated with serum ERT concentrations, independently of age, sex, education, household income, marital status, and health status of participants, or possible alcohol-induced organ damage. The relationship between ERT and ADMA offers a potential explanation for the interplay between ERT, and decreased risk of cardiometabolic disease and all-cause mortality. Also, it provides new mechanistic insights into the association between alcohol consumption and cardiovascular diseases, possibly mediated by ADMA metabolic pathways.
GRAU DE DIVERSIFICAÇÃO EMPRESARIAL E COMPETITIVIDADE DE SORTIMENTO EM CATEGORIAS DE PRODUTOS

description: Uma empresa que adota estratégia de maior diversificação - ampliando o escopo de negócios e categorias de produtos - fica exposta a concorrentes que adotam estratégias de menor diversificação em negócios ou categorias de produtos específicos, lhes proporcionando maior capacidade competitiva. O desejo de um maior ou menor grau de diversificação depende, portanto, do contexto histórico e variáveis de natureza setorial e regional que determinam o nível de concorrência entre as empresas e a exigência de recursos para competir. Medir a distinção, entre empresas que concorrem através de seus produtos ofertados, contribui para a tomada de decisão de acionistas. O que se pretende: Objetivo Geral - Identificar como o grau de diversificação de negócios e de produtos se relaciona com a competitividade de sortimento. Objetivo Específico 1 - Propor um critério de classificação e coleta de dados para um conjunto de categorias de produtos de consumo de empresas que atuam no Brasil; Objetivo Específico 2 - Propor métricas para avaliar o grau de diversificação em função dos níveis hierarquizados de negócios e produtos; Objetivo Específico 3 - Identificar, para um conjunto de categorias de produtos de consumo, empresas que atuam no Brasil com diferentes estratégias de diversificação; Objetivo Específico 4 - Avaliar o grau de competitividade de sortimento das empresas amostradas no nível de categorias de produtos específicas e relacionar com o grau de diversificação. Este é um estudo com cunho quantitativo. Para uma análise mais detalhada e aprofundada, foram intencionalmente selecionadas 33 categorias de produtos com um cadastro de três negócios: Alimentos e Bebidas, Saúde e Beleza, Casa e Jardim. Na análise de profundidade foi possível identificar que as empresas muito diversificadas não atuam com profundidade, enquanto empresas que propõem atender poucos ou negócios únicos e poucos departamentos, relacionados entre si, procuram se especializar e diversificar nas categorias de produtos pertencentes a estes negócios. A Unilever é a empresa mais diversificada, por ter o maior índice de diversificação, porém, é a 64ª empresa em profundidade, tem alto grau de profundidade em poucas categorias de produtos, quando analisada nos níveis de categorias de produtos, se iguala ou pode ser superada por empresas concentradas. É possível observar que não há empresas com alto grau de profundidade e alto grau de diversificação, simultaneamente, o que pode indicar o pressuposto que empresas que optam por estratégia de diversificação não buscam se especializar em uma única ou em poucas categorias de produtos. Também, as empresas mais diversificadas podem não criar vantagem competitiva, ou criar valor econômico, e cada vez menos estão distantes dos concorrentes.

A Lagrangian kinetic model for collisionless magnetic reconnection

description: A new fully kinetic system is proposed for modeling collisionless magnetic reconnection. The formulation relies on fundamental principles in Lagrangian dynamics, in which the inertia of the electron mean flow is neglected in the expression of the Lagrangian, rather then enforcing a zero electron mass in the equations of motion. This is done upon splitting the electron velocity into its mean and fluctuating parts, so that the latter naturally produce the corresponding pressure tensor. The model exhibits a new Coriolis force term, which emerges from a change of frame in the electron dynamics. Then, if the electron heat flux is neglected, the strong electron magnetization limit yields a hybrid model, in which the electron pressure tensor is frozen into the electron mean velocity.

description: Additional file 1: Figure S1. Overview of AS analysis in HIV-infected and non-infected human primary resting CD4+ T-cells. We obtained RNA-seq data for infected and non-infected cells from SRA (reference number SRR5071107-SRR5071122). There are four different treatment groups, and group contained four different cells. We then performed general quality control on the reads, aligned them to the hg19 human reference genome, and selected junction reads to identify alternatively spliced exons. Next, we identified mRNAs with differential alternatively splicing between the case group and each control. The percent spliced in (PSI) ratio indicates the level of differential exon expression. We adjusted q value < 0.05, and used PSI > 0.01 as the cutoff for differential splicing. Finally, we performed functional gene set enrichment analysis and classified genes with differential spliced exons in HIV infected T-cells according to their functional roles. Figure S2. 23 canonical pathways enriched in 427 HIV-associated AS genes. The red line indicates the cutoff FDR value, q < 0.05. Figure S3. 21 GO terms enriched in 427 HIV-associated AS genes.

A Model for the 19th Century Eruption of Eta Carinae: CSM Interaction Like a Scaled-Down Type IIn Supernova

Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

subject: FOS: Physical sciences

description: This paper proposes a simple model for the 19th century eruption of Eta Carinae that consists of two components: (1) a strong wind (MdotM=0.33 Msun/yr; v=200 km/s), blowing for 30 years, followed by (2) a 1e50 erg explosion in 1844. The ensuing collision between the fast ejecta and the CSM causes an increase in brightness observed at the end of 1844, followed by a sustained high-luminosity phase lasting for 10-15 years that matches the historical light curve. The emergent luminosity is powered by CSM interaction, analogous to the process in luminous Type IIn supernovae, except with 10 times lower explosion energy and at slower speeds (causing a longer duration and lower emergent luminosity). Such an explosive event provides a natural explanation for the light curve evolution, but also accounts for a number of puzzling attributes of the Homunculus nebula: (1) rough equipartition of total radiated and kinetic energy, (2) the double-shell structure of the Homunculus, (3) the apparent single age and Hubble-like flow resulting from the thin swept-up shell, (4) the complex mottled appearance of the polar lobes in HST images, arising from Raleigh-Taylor or Vishniac instabilities, (5) efficient and rapid dust formation, as seen in Type IIn supernovae, and (6) the fast (5000 km/s) material outside the Homunculus, arising from the acceleration of the forward shock upon exiting the dense CSM. In principle, the bipolar shape has already been explained in earlier studies of interacting winds, except that here the CSM interaction occurs over only 10 years, producing a thin shell with the resulting structures then frozen-in to the expanding bipolar nebula. This self-consistent picture has a number of implications for other eruptive transients, many of which may also be powered by CSM interaction.

description: We compute cosmic ray (CR) nuclei, proton, antiproton, electron and positron spectra below 1 TeV at Earth by means of a detailed transport description in the galaxy and in the solar system. CR spectra below 10 GeV are strongly modified by charge-sign dependent propagation effects. These depend on the polarity of the solar magnetic field and therefore vary with the solar cycle. The puzzling discrepancy between the low-energy positron fraction measured by PAMELA and AMS-01 is then easily explained by their different data-taking epochs. We reproduce the observed spectra of CR light nuclei within the same galactic and solar-system propagation model.

While young brown dwarfs share many properties with solar-mass T Tauri stars, differences may be used as tests of how the physics of accretion/outflow and disk chemistry/dissipation depend on the mass of the central object. This article summarizes the presentations and discussions during the splinter session on 'Disks, accretion and outflows of brown dwarfs' held at the CoolStars17 conference in Barcelona in June 2012. Recent results in the field of brown dwarf disks and outflows include the determination of brown dwarf disk masses and geometries based on Herschel far-IR photometry (70-160 um), accretion properties based on X-Shooter spectra, and new outflow detections in the very low-mass regime.

description: The induced diffusion of tracers in a bacterial suspension is studied theoretically and experimentally at low bacterial concentrations. Considering the swimmer-tracer hydrodynamic interactions at low-Reynolds number and using a kinetic theory approach, it is shown that the induced diffusion coefficient is proportional to the swimmer concentration, their mean velocity and a coefficient $β$, as observed experimentally. The coefficient $β$ scales as the tracer-swimmer cross section times the mean square displacement produced by single scatterings. The displacements depend on the swimmer propulsion forces. Considering simple swimmer models (acting on the fluid as two monopoles or as a force dipole) it is shown that $β$ increases for decreasing swimming efficiencies. Close to solid surfaces the swimming efficiency degrades and, consequently, the induced diffusion increase. Experiments on W wild-type {\em Escherichia coli} in a Hele-Shaw cell under buoyant conditions are performed to measure the induced diffusion on tracers near surfaces. The modification of the suspension pH vary the swimmers' velocity in a wide range allowing to extract the $β$ coefficient with precision. It is found that the solid surfaces modify the induced diffusion: decreasing the confinement height of the cell, $β$ increases by a factor 4. The theoretical model reproduces this increase although there are quantitative differences, probably attributed to the simplicity of the swimmer models.

Corrugated flat band as an origin of large thermopower in hole doped PtSb$_2$

description: The origin of the recently discovered large thermopower in hole-doped PtSb$_2$ is theoretically analyzed based on a model constructed from first principles band calculation. It is found that the valence band dispersion has an overall flatness combined with some local ups and downs, which gives small Fermi surfaces scattered over the entire Brillouin zone. The Seebeck coefficient is calculated using this model, which gives good agreement with the experiment. We conclude that the good thermoelectric property originates from this "corrugated flat band", where the coexistence of large Seebeck coefficient and large electric conductivity is generally expected.

Purely competitive evolutionary dynamics for games

description: We introduce and analyze a purely competitive dynamics for the evolution of an infinite population subject to a 3-strategy game. We argue that this dynamics represents a characterization of how certain systems, both natural and artificial, are governed. In each period, the population is randomly sorted into pairs, which engage in a once-off play of the game; the probability that a member propagates its type to its offspring is proportional only to its payoff within the pair. We show that if a type is dominant (obtains higher payoffs in games with both other types), its 'pure' population state, comprising only members of that type, is globally attracting. If there is no dominant type, there is an unstable 'mixed' fixed point; the population state eventually oscillates between the three near-pure states. We then allow for mutations, where offspring have a non-zero probability of randomly changing their type. In this case, the existence of a dominant type renders a point near its pure state globally attracting. If no dominant type exists, a supercritical Hopf bifurcation occurs at the unique mixed fixed point, and above a critical (typically low) mutation rate, this fixed point becomes globally attracting: the implication is that even very low mutation rates can stabilize a system that would, in the absence of mutations, be unstable.

The Effect of Density on the Thermal Structure of Gravitationally-Darkened Be Star Disks

description: The effects of gravitational darkening on the thermal structure of Be star disks of differing densities are systematically examined. Gravitational darkening is the decrease of the effective temperature near the equator and the corresponding increase near the poles of a star caused by rapid rotation. We also include the rotational distortion of the star using the Roche Model. Increasing the disk density increases the optical depths in the equatorial plane, resulting in the formation of an inner cool region near the equatorial plane of the disk. High rotation rates result in disks that have temperatures similar to those of a denser disk, namely cooler overall. However the effect of increasing rotation produces additional heating in the upper disk due to the hotter stellar pole. Cool regions in the equatorial plane normally associated with high density are seen in low density models at high rotation rates. Gravitational darkening increases the amount of very cool and very hot material in the disk and decreases the amount of disk material at moderate temperatures. We also present models which study the effect of gravitational darkening on hydrostatically-converged disks, in which the temperature structure is consistent with vertical hydrostatic equilibrium. Because the equatorial regions become cooler, hydrostatically converged models that include gravity darkening have smaller vertical scale heights, and $H/R$ is smaller by as much as 56% near $v_{\rm crit}$. Finally we explore differences in disk temperatures when alternate formulations of gravitational darkening, which lower the temperature difference between the pole and the equator, are used.

Stimulated Brillouin Scattering Thresholds in Optical Fibers for Lasers Linewidth Broadened with Noise

description: Phase and/or intensity modulation techniques to broaden the Linewidth of an optical source are well known methods to suppress stimulated Brillouin scattering (SBS) in optical fibers. A common technique used to achieve significant bandwidth enhancement in a simple fashion is to phase modulate with a filtered noise source. We will demonstrate here that, in this case the stochastic nature of noise requires an inclusion of length dependent corrections to the SBS threshold enhancement. This effect becomes particularly significant for short fiber lengths common to most high power fiber amplifiers.
