Extended Jackiw-Pi Model and Its Supersymmetrization

We present an extended version of the so-called Jackiw-Pi (JP) model in three
dimensions, and perform its supersymmetrization. Our field content has three
multiplets: (i) Yang-Mills vector multiplet $(A_\mu{}^I, \lambda^I)$, (ii)
Parity-odd extra vector multiplet $(B_\mu{}^I, \chi^I)$, and (iii) Scalar
multiplet $(C^I, \rho^I, f^I)$. The bosonic fields in these multiplets are the
same as the original JP-model, except for the auxiliary field $~f^I$ which is
new, while the fermions $\lambda^I, \chi^I$ and $\rho^I$ are their
super-partners. The basic difference from the original JP-model is the presence
of the kinetic term for $C^I$ with its modified field-strength $H_\mu{}^I
\equiv D_\mu C^I + m B_\mu{}^I$. The inclusion of the $C^I$-kinetic term is to
comply with the recently-developed tensor hierarchy formulation for
supersymmetrization.Comment: 12 pages, 0 figur
Surface transport in plasma-balls

We study the surface transport properties of stationary localized
configurations of relativistic fluids to the first two non-trivial orders in a
derivative expansion. By demanding that these finite lumps of relativistic
fluid are described by a thermal partition function with arbitrary stationary
background metric and gauge fields, we are able to find several constraints
among surface transport coefficients. At leading order, besides recovering the
surface thermodynamics, we obtain a generalization of the Young-Laplace
equation for relativistic fluid surfaces, by considering a temperature
dependence in the surface tension, which is further generalized in the context
of superfluids. At the next order, for uncharged fluids in 3+1 dimensions, we
show that besides the 3 independent bulk transport coefficients previously
known, a generic localized configuration is characterized by 3 additional
surface transport coefficients, one of which may be identified with the surface
modulus of rigidity. Finally, as an application, we study the effect of
temperature dependence of surface tension on some explicit examples of
localized fluid configurations, which are dual to certain non-trivial black
hole solutions via the AdS/CFT correspondence.Comment: v2: 37+1pp, 3 figures, typos fixed, added new appendix with

Governing PatientsLikeMe: information production and research through an open, distributed and data-based social media network

types: articleMany organizations develop social media networks with the aim of engaging a wide range of social groups in the production of information that fuels their processes. This effort appears to crucially depend on complex data structures that allow the organization to connect and collect data from a myriad of local contexts and actors. One such organization, PatientsLikeMe, is developing a platform with the aim of connecting patients with one another while collecting self-reported medical data, which it uses for scientific and commercial medical research. Here the question of how technology and the underlying data structures shape the kind of information and medical evidence that can be produced through social media-based arrangements comes powerfully to the fore. In this observational case study, I introduce the concepts of information cultivation and social denomination to explicate how the development of such a data collection architecture requires a continuous exercise of balancing between the conflicting demands of patient engagement, necessary for collecting data in scale, and data semantic context, necessary for effective capture of health phenomena in informative and specific data. The study extends the understanding of the context-embeddedness of information phenomena and discusses some of the social consequences of social media models for knowledge making
Genome-wide Association for Major Depression Through Age at Onset Stratification: Major Depressive Disorder Working Group of the Psychiatric Genomics Consortium

© 2016 Society of Biological Psychiatry. This is an open access article under the CC BY license (http://creativecommons.org/licenses/by/4.0/).BACKGROUND: Major depressive disorder (MDD) is a disabling mood disorder, and despite a known heritable component, a large meta-analysis of genome-wide association studies revealed no replicable genetic risk variants. Given prior evidence of heterogeneity by age at onset in MDD, we tested whether genome-wide significant risk variants for MDD could be identified in cases subdivided by age at onset.

METHODS: Discovery case-control genome-wide association studies were performed where cases were stratified using increasing/decreasing age-at-onset cutoffs; significant single nucleotide polymorphisms were tested in nine independent replication samples, giving a total sample of 22,158 cases and 133,749 control subjects for subsetting. Polygenic score analysis was used to examine whether differences in shared genetic risk exists between earlier and adult-onset MDD with commonly comorbid disorders of schizophrenia, bipolar disorder, Alzheimer’s disease, and coronary artery disease.

RESULTS: We identified one replicated genome-wide significant locus associated with adult-onset (.27 years) MDD (rs7647854, odds ratio: 1.16, 95% confidence interval: 1.11–1.21, p 5 5.2 3 10-11). Using polygenic score analyses, we show that earlier-onset MDD is genetically more similar to schizophrenia and bipolar  disorder than adult-onset MDD. 

CONCLUSIONS: We demonstrate that using additional phenotype data previously collected by genetic studies to tackle phenotypic heterogeneity in MDD can successfully lead to the discovery of genetic risk factor despite reduced sample size. Furthermore, our results suggest that the genetic susceptibility to MDD differs between adult- and earlier-onset MDD, with earlier-onset cases having a greater genetic overlap with schizophrenia and bipolar disorder
Midwives' views on appropriate antenatal counselling for congenital anomaly tests: Do they match clients' preferences?

Contains fulltext :
                  137446.pdf (publisher's version ) (Open Access)OBJECTIVE: this study aims to provide insight into: (a) midwives' views on appropriate antenatal counselling for congenital anomaly tests, and (b) whether these views match clients' preferences regarding antenatal counselling. DESIGN: a comparative (midwives versus clients) questionnaire survey. Cognitive interviews (n=8) were used to validate the internal validity of the midwifery questionnaire results. PARTICIPANTS AND SETTING: 1416 Dutch midwives (response 62%) completed a questionnaire measuring their views on appropriate antenatal counselling for congenital anomaly tests. MEASUREMENTS: we used the 58-item midwives' version of the QUOTE (prenatal), an instrument to assess clients' counselling preferences. Descriptive statistics were used to explore midwives' views on appropriate counselling and how these relate to client preferences as measured previously with the clients' version of the QUOTE (prenatal). FINDINGS: almost all midwives consider the client-midwife relation (100%) and health education (95%) to be (very) important for appropriate antenatal counselling for congenital anomaly tests. Almost half of the midwives consider decision-making support (47%) to be (very) important. These findings are practically congruent with client preferences. Still, clinically relevant differences were found regarding 13 individual items, e.g. more clients than midwives value 'medical information about congenital anomalies' and 'getting advice whether to take prenatal tests or not'. KEY CONCLUSION: like clients, most midwives value a good client-midwife relation and health education as (very) important for antenatal counselling for congenital anomaly tests. Less than half of them value decision-making support. These findings are in contrast with the literature in which decision-making support is seen as the most important part of antenatal counselling for congenital anomaly tests. IMPLICATION FOR PRACTICE: preferably, antenatal counselling for congenital anomaly tests should be consistent with the three-function model of antenatal counselling i.e. maintaining a client-midwife relation, providing health education as well as decision-making support, and tailored to clients' individual preferences. As not all midwives subscribe to these functions, reflection on their views is important. Furthermore, midwives need to bridge their views on appropriate antenatal counselling and client preferences. To do so, midwives may benefit from the Shared Decision Making approach
Search for long-lived neutral particles decaying into lepton jets in proton-proton collisions at root s=8 Tev with the ATLAS detector

Several models of physics beyond the Standard Model predict neutral particles that decay into final states consisting of collimated jets of light leptons and hadrons (so-called "lepton jets"). These particles can also be long-lived with decay length comparable to, or even larger than, the LHC detectors' linear dimensions. This paper presents the results of a search for lepton jets in proton-proton collisions at the centre-of-mass energy of root s = 8 TeV in a sample of 20.3 fb(-1) collected during 2012 with the ATLAS detector at the LHC. Limits on models predicting Higgs boson decays to neutral long-lived lepton jets are derived as a function of the particle's proper decay length
Measurement of the mass difference between top and anti-top quarks in pp collisions at root s=7 TeV using the ATLAS detector

A measurement of the mass difference between top and anti-top quarks is presented. In a 4.7 fb(-1) data sample of proton-proton collisions at root s = 7 TeV recorded with the ATLAS detector at the LHC, events consistent with t (t) over bar production and decay into a single charged lepton final state are reconstructed. For each event, the mass difference between the top and anti-top quark candidate is calculated. A two b-tag requirement is used in order to reduce the background contribution. A maximum likelihood fit to these per-event mass differences yields Delta m = m(t) - m((t) over bar) = 0.67 +/- 0.61 (stat) +/- 0.41 (syst) GeV, consistent with CPT invariance
Nonparametric adaptive estimation for integrated diffusions.

International audienceWe consider here nonparametric estimation for integrated diffusion processes. Let $(V_t)$ be a stationary and $\beta$-mixing diffusion with unknown drift and diffusion coefficient. The integrated process $X_t= \int_0^{t} V_s ds$ is observed at discrete times with regular sampling interval $\Delta$. For both the drift function and the diffusion coefficient of the unobserved diffusion $(V_t)$, we propose nonparametric estimators based on a penalized least square approach. Estimators are chosen among a collection of functions belonging to a finite dimensional space selected by an automatic data-driven method. We derive non asymptotic risk bounds for the estimators. Interpreting these bounds through the asymptotic framework of high frequency data, we show that our estimators reach the minimax optimal rates of convergence. The algorithms of estimation are implemented for several examples of diffusion models that can be exactly simulated
Spectrophotometric analysis of gamma-ray burst afterglow extinction curves with X-Shooter

International audienceWe use gamma-ray burst (GRB) afterglow spectra observed with the VLT/X-Shooter spectrograph to measure rest-frame extinction in GRB lines-of-sight by modelling the broadband near-infrared (NIR) to X-ray afterglow spectral energy distributions (SEDs). Our sample consists of nine Swift GRBs, of which eight belong to the long-duration and one to the short-duration class. Dust is modelled using the average extinction curves of the Milky Way and the two Magellanic Clouds. We derive the rest-frame extinction of the entire sample, which fall in the range 0 ≲ AV ≲ 1.2. Moreover, the SMC extinction curve is the preferred extinction curve template for the majority of our sample, a result that is in agreement with those commonly observed in GRB lines of sights. In one analysed case (GRB 120119A), the common extinction curve templates fail to reproduce the observed extinction. To illustrate the advantage of using the high-quality, X-Shooter afterglow SEDs over the photometric SEDs, we repeat the modelling using the broadband SEDs with the NIR-to-UV photometric measurements instead of the spectra. The main result is that the spectroscopic data, thanks to a combination of excellent resolution and coverage of the blue part of the SED, are more successful in constraining extinction curves and therefore dust properties in GRB hosts with respect to photometric measurements. In all cases but one the extinction curve of one template is preferred over the others. We show that themodelled values of the extinction AV and the spectral slope, obtained through spectroscopic and photometric SED analysis, can differ significantly for individual events, though no apparent trend in the differences is observed. Finally we stress that, regardless of the resolution of the optical-to-NIR data, the SED modelling gives reliable results only when the fit is performed on a SED covering a broader spectral region (in our case extending to X-rays)
CLASH-VLT: The stellar mass function and stellar mass density profile of the z = 0.44 cluster of galaxies MACS J1206.2-0847

International audienceContext. The study of the galaxy stellar mass function (SMF) in relation to the galaxy environment and the stellar mass density profile, ρ⋆(r), is a powerful tool to constrain models of galaxy evolution.Aims. We determine the SMF of the z = 0.44 cluster of galaxies MACS J1206.2-0847 separately for passive and star-forming (SF) galaxies, in different regions of the cluster, from the center out to approximately 2 virial radii. We also determine ρ⋆(r) to compare it to the number density and total mass density profiles. Methods. We use the dataset from the CLASH-VLT survey. Stellar masses are obtained by spectral energy distribution fitting with the MAGPHYS technique on 5-band photometric data obtained at the Subaru telescope. We identify 1363 cluster members down to a stellar mass of 109.5 M⊙, selected on the basis of their spectroscopic (~1/3 of the total) and photometric redshifts. We correct our sample for incompleteness and contamination by non members. Cluster member environments are defined using either the clustercentric radius or the local galaxy number density. Results. The whole cluster SMF is well fitted by a double Schechter function, which is the sum of the two Schechter functions that provide good fits to the SMFs of, separately, the passive and SF cluster populations. The SMF of SF galaxies is significantly steeper than the SMF of passive galaxies at the faint end. The SMF of the SF cluster galaxies does not depend on the environment. The SMF of the passive cluster galaxies has a significantly smaller slope (in absolute value) in the innermost (≤ 0.50 Mpc, i.e., ~0.25 virial radii), and in the highest density cluster region than in more external, lower density regions. The number ratio of giant/subgiant galaxies is maximum in this innermost region and minimum in the adjacent region, but then gently increases again toward the cluster outskirts. This is also reflected in a decreasing radial trend of the average stellar mass per cluster galaxy. On the other hand, the stellar mass fraction, i.e., the ratio of stellar to total cluster mass, does not show any significant radial trend. Conclusions. Our results appear consistent with a scenario in which SF galaxies evolve into passive galaxies due to density-dependent environmental processes and eventually get destroyed very near the cluster center to become part of a diffuse intracluster medium. Dynamical friction, on the other hand, does not seem to play an important role. Future investigations of other clusters of the CLASH-VLT sample will allow us to confirm our interpretation
Measurement of electrons from heavy-flavour hadron decays in p–Pb collisions at √sNN=5.02 TeV

The production of electrons from heavy-flavour hadron decays was measured as a function of transverse momentum (pT) in minimum-bias p–Pbcollisions at √sNN=5.02TeVusing the ALICE detector at the LHC. The measurement covers the pTinterval 0.5 <pT<12GeV/cand the rapidity range −1.065 <ycms<0.135in the centre-of-mass reference frame. The contribution of electrons from background sources was subtracted using an invariant mass approach. The nuclear modification factor RpPbwas calculated by comparing the pT-differential invariant cross section in p–Pb collisions to a pp reference at the same centre-of-mass energy, which was obtained by interpolating measurements at √s=2.76TeVand √s=7TeV. The RpPbis consistent with unity within uncertainties of about 25%, which become larger for pTbelow 1GeV/c. The measurement shows that heavy-flavour production is consistent with binary scaling, so that a suppression in the high-pTyield in Pb–Pb collisions has to be attributed to effects induced by the hot medium produced in the final state. The data in p–Pb collisions are described by recent model calculations that include cold nuclear matter effects
A planetary system with gas giants and super-Earths around the nearby M
  dwarf GJ 676A. Optimizing data analysis techniques for the detection of
  multi-planetary systems

Several M dwarfs are targets of systematical monitoring in searches for
Doppler signals caused by low-mass exoplanet companions. As a result, an
emerging population of high-multiplicity planetary systems around low-mass
stars are being detected as well. We optimize classic data analysis methods and
develop new ones to enhance sensitivity towards low-amplitude planets in
high-multiplicity systems. We apply these methods to the public HARPS
observations of GJ 676A, a nearby M dwarf with one reported gas giant
companion. We re-derived Doppler measurements using the template matching
method (HARPS-TERRA). We used refined versions of periodograms to assess the
presence of additional low-mass companions. We analyse the same dataset with
Bayesian tools and compared the performance of both approaches. We confirm the
reported massive gas giant candidate and a long period trend, whose curvature
is now well detected. We also find very secure evidence of two new candidates
in close-in orbits and masses in the super-Earth mass regime. Despite the
increased sensitivity of the new periodogram tools, we find that Bayesian
methods are more sensitive in the early detection of candidate signals. While
hardware development is important, development of data analysis techniques can
help to reveal new results from existing data sets with significantly fewer
resources. This new system holds the record of minimum-mass range (from Msin i
= 4.5 M_Earth to 5 M_Jup) and period range (from 3.6 days to more than 10
years). Although all the planet candidates are substantially more massive, it
is the first exoplanetary system with a general architecture similar to our
solar system. GJ 676A can be happily added to the family of high-multiplicity
planetary systems around M dwarfs.Comment: Accepted to A&A. 10 pages, 5 Figures, 5 Tables. Discussion on

Theoretical uncertainties on quasielastic charged-current neutrino-nucleus cross sections

We estimate the theoretical uncertainties of the model developed in [J. Nieves, J.E. Amaro, M. Valverde, Phys. Rev. C 70 (2004) 055503] for inclusive quasielastic charged-current neutrino-nucleus reactions at intermediate energies. Besides we quantify the deviations of the predictions of this many body framework from those obtained within a simple Fermi gas model. A special attention has been paid to the ratio sigma(mu)/sigma(e) of interest for experiments on atmospheric neutrinos. We show that uncertainties affecting this ratio are likely smaller than 5%
Shannon entropy of brain functional complex networks under the influence
  of the psychedelic Ayahuasca

The entropic brain hypothesis holds that the key facts concerning
psychedelics are partially explained in terms of increased entropy of the
brain's functional connectivity. Ayahuasca is a psychedelic beverage of
Amazonian indigenous origin with legal status in Brazil in religious and
scientific settings. In this context, we use tools and concepts from the theory
of complex networks to analyze resting state fMRI data of the brains of human
subjects under two distinct conditions: (i) under ordinary waking state and
(ii) in an altered state of consciousness induced by ingestion of Ayahuasca. We
report an increase in the Shannon entropy of the degree distribution of the
networks subsequent to Ayahuasca ingestion. We also find increased local and
decreased global network integration. Our results are broadly consistent with
the entropic brain hypothesis. Finally, we discuss our findings in the context
of descriptions of "mind-expansion" frequently seen in self-reports of users of
psychedelic drugs.Comment: 27 pages, 6 figure
Business and society on the transitional periphery: Comparative perspectives

© 2015 Elsevier Ltd. This article looks at business and society on the transitional periphery from a starting point rooted in the international business literature. Many transitional periphery countries have rich natural resource endowments or prosperous diasporas, making it relatively easy to attract inward FDI, chronic institutional weaknesses and policy failures notwithstanding. At the same time, such windfalls may dilute incentives for institution building or reform. We review trends emerging from the most recent scholarly work in the area, and highlight potential research agendas for the future
Resilience of Zostera muelleri seagrass to small-scale disturbances: the relative importance of asexual versus sexual recovery

Resilience is the ability of an ecosystem to recover from disturbance without loss of essential function. Seagrass ecosystems are key marine and estuarine habitats that are under threat from a variety of natural and anthropogenic disturbances. The ability of these ecosystems to recovery from disturbance will to a large extent depend on the internsity and scale of the disturbance, and the relative importance of sexual versus asexual reproduction within populations. Here, we investigated the resilience of Zostera muelleri seagrass (Syn. Zostera capricorni) to small-scale disturbances at four locations in Lake Macquarie Australias largest coastal lake and monitored recovery over a 65-week period. Resilience of Z. muelleri varied significantly with disturbance intensity; Z. muelleri recovered rapidly (within 2 weeks) from low-intensity disturbance (shoot loss), and rates of recovery appeared related to initial shoot length. Recovery via rhizome encroachment (asexual regeneration) from high-intensity disturbance (loss of entire plant) varied among locations, ranging from 18-35 weeks, whereas the ability to recover was apparently lost (at least within the time frame of this study) when recovery depended on sexual regeneration, suggesting that seeds do not provide a mechanism of recovery against intense small-scale disturbances. The lack of sexual recruits into disturbed sites is surprising as our initial surveys of genotypic diversity (using nine polymorphic microsatellite loci) at these location indicate that populations are maintained by a mix of sexual and asexual reproduction (genotypic diversity [R] varied from 0.24 to 0.44), and populations consisted of a mosaic of genotypes with on average 3.6 unique multilocus genotypes per 300 mm diameter plot. We therefore conclude that Z. muelleri populations within Lake Macquarie rely on clonal growth to recover from small-scale disturbances and that ongoing sexual recruitment by seeds into established seagrass beds (a
