Super-solar metallicity at the position of the ultra-long GRB 130925A

Over the last decade there has been immense progress in the follow-up of short and long gamma-ray bursts (GRBs), resulting in a significant rise in the detection rate of X-ray and optical afterglows, in the determination of GRB redshifts, and of the identification of the underlying host galaxies. Nevertheless, our theoretical understanding of the progenitors and central engines powering these vast explosions is lagging behind, and a newly identified class of ultra-long GRBs has fuelled speculation on the existence of a new channel of GRB formation. In this paper we present high signal-to-noise X-Shooter observations of the host galaxy of GRB 130925A, which is the fourth unambiguously identified ultra-long GRB, with prompt γ-ray emission detected for ~20 ks. The GRB line of sight was close to the host galaxy nucleus, and our spectroscopic observations cover this region along the bulge/disk of the galaxy and a bright star-forming region within the outskirts of the galaxy. From our broad wavelength coverage, we obtain accurate metallicity and dust-extinction measurements at the galaxy nucleus and at an outer star-forming region, and measure a super-solar metallicity at both locations, placing this galaxy within the 10–20% most metal-rich GRB host galaxies. Such a high metal enrichment has significant implications on the progenitor models of both long and ultra-long GRBs, although the edge-on orientation of the host galaxy does not allow us to rule out a large metallicity variation along our line of sight. The spatially resolved spectroscopic observations presented in this paper offer important insight into variations in the metal and dust abundance within GRB host galaxies. However, they also illustrate the need for integral field unit observations on a larger sample of GRB host galaxies of a variety of metallicities to provide a more quantitative view on the relation between the GRB circumburst environment and the galaxy-whole properties.Peer-reviewedPublisher Versio
Order 1/N2 test of the Maldacena conjecture II : the full bulk one-loop contribution to the boundary Weyl anomaly.

We compute the complete bulk one-loop contribution to the Weyl anomaly of the boundary theory for IIB supergravity compactified on AdS5×S5. The result, that , reproduces the subleading term in the exact expression  for the Weyl anomaly of  super-Yang–Mills theory, confirming the Maldacena conjecture. The anomaly receives contributions from all multiplets casting doubt on the possibility of describing the boundary theory beyond leading order in N by a consistent truncation to the ‘massless’ multiplet of IIB supergravity
Demonstration of a self-recovering ALU using a convergent cellular automata.

This paper presents work in progress towards the demonstration of a self-restoring arithmetic logic unit (ALU) based on convergent cellular automata (CCA). The need for fault tolerance and self-recovery strategies for electronic circuits is discussed, with particular focus on well-known redundancy and reconfiguration approaches. Our CCA fault tolerant strategy is demonstrated via MATLAB simulation using fault injection. The combined roles of the CCA as coordination layer and restoration agent are discussed. Work in progress towards a hardware demonstration using VHDL description and FPGA hardware is also described
Developing a framework of responsible innovation.

The governance of emerging science and innovation is a major challenge for contemporary democracies. In this paper we present a framework for understanding and supporting efforts aimed at ‘responsible innovation’. The framework was developed in part through work with one of the first major research projects in the controversial area of geoengineering, funded by the UK Research Councils. We describe this case study, and how this became a location to articulate and explore four integrated dimensions of responsible innovation: anticipation, reflexivity, inclusion and responsiveness. Although the framework for responsible innovation was designed for use by the UK Research Councils and the scientific communities they support, we argue that it has more general application and relevance
Business and society on the transitional periphery : comparative perspectives

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
Gauge and Supersymmetry Invariance of N=2 Boundary Chern-Simons Theory

In this paper, we study the restoration of gauge symmetry and up to half the
supersymmetry (N=(2,0) or N=(1,1) in two dimensions) for N=2 non-Abelian
Chern-Simons theories in the presence of a boundary. We describe the boundary
action which is a supersymmetric WZW model coupled to the bulk Chern-Simons
theory. Unlike the N=1 case, higher supersymmetry (N=(2,0)) will endow the
group manifold of the WZW model with a complex structure. Therefore, the
N=(2,0) WZW model in our paper is constructed via a coset space $G_c/G$, where
$G$ is the same as the gauge group in the Chern-Simons action.Comment: 26 pages, accepted version. Corrected the arguments in pages 18-19,

Non-renormalization of the $V\bar cc$-vertices in ${\cal N}=1$
  supersymmetric theories

Using the Slavnov--Taylor identities we prove that the three-point ghost
vertices with a single line of the quantum gauge superfield are not
renormalized in all loops in ${\cal N}=1$ supersymmetric gauge theories. This
statement is verified by the explicit one-loop calculation made by the help of
the BRST invariant version of the higher covariant derivative regularization.
Using the restrictions to the renormalization constants which are imposed by
the non-renormalization of the considered vertices we express the exact NSVZ
$\beta$-function in terms of the anomalous dimensions of the Faddeev--Popov
ghosts and of the quantum gauge superfield. In the expression for the NSVZ
$\beta$-function obtained in this way the contributions of the Faddeev--Popov
ghosts and of the matter superfields have the same structure.Comment: 21 pages, 5 figures, a misprint in Eqs. (55) and (58) is correcte
Heavy-quark spin symmetry partners of the $X(3872)$ revisited

We revisit the consequences of the heavy-quark spin symmetry for the possible
spin partners of the $X(3872)$. We confirm that, if the $X(3872)$ were a
$D\bar{D}^*$ molecular state with the quantum numbers $J^{PC}=1^{++}$, then in
the strict heavy-quark limit there should exist three more hadronic molecules
degenerate with the $X(3872)$, with the quantum numbers $0^{++}$, $1^{+-}$, and
$2^{++}$ in line with previous results reported in the literature. We
demonstrate that this result is robust with respect to the inclusion of the
one-pion exchange interaction between the $D$ mesons. However, this is true
only if all relevant partial waves as well as particle channels which are
coupled via the pion-exchange potential are taken into account. Otherwise, the
heavy-quark symmetry is destroyed even in the heavy-quark limit. Finally, we
solve the coupled-channel problem in the $2^{++}$ channel with nonperturbative
pions beyond the heavy-quark limit and, contrary to the findings of previous
calculations with perturbative pions, find for the spin-2 partner of the
$X(3872)$ a significant shift of the mass as well as a width of the order of 50
MeV.Comment: 17 pages, 3 figures, 1 table, version published in Phys.Lett.
Structure of the Harmonic Oscillator in the space of $n$-particle
  Glauber correlators

We map the Hilbert space of the quantum Harmonic oscillator to the space of
Glauber's $n$th-order intensity correlators, in effect showing "the
correlations between the correlators" for a random sampling of the quantum
states. In particular, we show how the popular $g^{(2)}$ function is correlated
to the mean population and how a recurrent criterion to identify
single-particle states or emitters, namely $g^{(2)}<1/2$, is incorrect as
states exist that satisfy this condition with average population larger than
one. Our charting of the Hilbert space allows to capture its structure in a
simpler and physically more intuitive way that can be used to classify quantum
sources by surveying which territory they can access.Comment: 12 pages, 5 figure
Cold DUst around NEarby Stars (DUNES). First results. A resolved exo-Kuiper belt around the solar-like star ζ2 Ret

We present the first far-IR observations of the solar-type stars δ Pav, HR 8501, 51 Peg and ζ^2 Ret, taken within the context of the DUNES Herschel open time key programme (OTKP). This project uses the PACS and SPIRE instruments with the objective of studying infrared excesses due to exo-Kuiper belts around nearby solar-type stars. The observed 100 μm fluxes from δ Pav, HR 8501, and 51 Peg agree with the predicted photospheric fluxes, excluding debris disks brighter than L_dust/L_* ~ 5 x 10^-7 (1σ level) around those stars. A flattened, disk-like structure with a semi-major axis of ~100 AU in size is detected around ζ2 Ret. The resolved structure suggests the presence of an eccentric dust ring, which we interpret as an exo-Kuiper belt with L_dust/L_* ≈ 10^-5
Working with cancer: health and employment among cancer survivors.

This is the author accepted manuscript. The final version is available from the publisher via the DOI in this record.Available online 4 August 2015PURPOSE: Cancer affects a growing proportion of US workers. Factors contributing to whether they continue or return to work after cancer diagnosis include: age, physical and mental health, health insurance, education, and cancer site. The purpose of this study was to assess the complex relationships between health indicators and employment status for adult cancer survivors. METHODS: We analyzed pooled data from the 1997-2012 US National Health Interview Survey (NHIS). Our sample included adults with a self-reported physician diagnosis of cancer (n = 24,810) and adults with no cancer history (n = 382,837). Using structural equation modeling (SEM), we evaluated the relationship between sociodemographic factors, cancer site, and physical and mental health indicators on the overall health and employment status among adults with a cancer history. RESULTS: The overall model for cancer survivors fit the data well (χ(2) (374) = 3654.7, P < .001; comparative fit index = 0.98; root mean square error of approximation = 0.04). Although black cancer survivors were less likely to report good-to-excellent health, along with Hispanic survivors, they were more likely to continue to work after diagnosis compared with their white counterparts. Health insurance status and educational level were strongly and positively associated with health status and current employment. Age and time since diagnosis were not significantly associated with health status or employment, but there were significant differences by cancer site. CONCLUSIONS: A proportion of cancer survivors may continue to work because of employment-based health insurance despite reporting poor health and significant physical and mental health limitations. Acute and long-term health and social support are essential for the continued productive employment and quality of life of all cancer survivors.The work was supported in part by a National Cancer Institute (NCI) fellowship at the National Institutes of Health (1F31CA153937); the National Institute for Occupational Safety and Health (NIOSH R01 OH03915); and the European Regional Development Fund Programme and European Social Fund Convergence Programme for Cornwall and the Isles of Scilly (the University of Exeter Medical School)
Vegetation dynamics at Raraku Lake catchment (Easter Island) during the past 34,000years

Easter Island is a paradigmatic example of human impact on ecosystems. The role of climate changes in recent vegetation shifts has commonly been rejected without proper assessment. A palynological study of a long sediment core from Raraku Lake documents the vegetation dynamics for the last 34 ka and investigates their driving forces, particularly the effects of climate variability on vegetation changes. Significant relationships between pollen assemblage changes and sedimentary and geochemical proxies demonstrate the rapid response of vegetation to lake crater basin hydrology and climatic changes. The lake surroundings were occupied by an open mixed palm grove during the Last Glacial period. Poaceae and Sophora increased at the expense of palms and Triumfetta, and Coprosma practically disappeared, in response to slightly wetter and/or colder climate during the Last Glacial Maximum. Palms and Triumfetta thrived in a warmer and/or drier climate during the deglaciation. Minor vegetation changes (a slight increase in Sophora and a drop in Asteraceae and Poaceae) occurred between 13.2 and 11.8 cal. ka BP and can be related to rapid changes in the Younger Dryas chronozone. The increase in herbaceous taxa indicates a gradual shallowing of the lake and development of a mire during the Holocene, caused by sediment infilling and warmer and drier climate. Relatively rapid vegetation changes in the Holocene were caused by climate and by plant succession on the expanding mire. The rates of vegetation change observed in the mire were similar to those at the initial stages of human impact identified in a previous study. These results reveal significant vegetation changes prior to human presence, due to the interplay of climate variations (temperature and moisture), changes in lake basin form by infilling and intrinsic dynamics of plant succession. Hence, the potential contribution of these factors in vegetation shifts during the period of human presence should not be neglected.This research was funded by the Spanish Ministry of Science and Education through the projects LAVOLTER (CGL2004-00683/BTE), GEOBILA (CGL2007-60932/BTE), CONSOLIDER GRACCIE (CSD2007-00067) and RapidNAO (CGL2014-40608R) and an undergraduate grant (BES-2008-002938 to N.

Close binary and other variable stars in the solar-age Galactic open cluster M 67

We present multi-colour time-series CCD photometry of the solar-age galactic open cluster M 67 (NGC 2682). About 3600 frames spread over 28 nights were obtained with the 1.5 m Russian-Turkish and 1.2 m Mercator telescopes. High-precision observations of the close binary stars AH Cnc, EV Cnc, ES Cnc, the δ Scuti type systems EX Cnc and EW Cnc, and some long-period variables belonging to M 67 are presented. Three full multi-colour light curves of the overcontact binary AH Cnc were obtained during three observing seasons. Likewise we gathered three light curves of EV Cnc, an EB-type binary, and two light curves of ES Cnc, a blue straggler binary. Parts of the light change of long-term variables S1024, S1040, S1045, S1063, S1242, and S1264 are obtained. Period variation analysis of AH Cnc, EV Cnc, and ES Cnc were done using all times of mid-eclipse available in the literature and those obtained in this study. In addition, we analyzed multi-colour light curves of the close binaries and also determined new frequencies for the δ Scuti systems. The physical parameters of the close binary stars were determined with simultaneous solutions of multi-colour light and radial velocity curves. Finally we determined the distance of M 67 as 857(33) pc via binary star parameters, which is consistent with an independent method from earlier studies. Based on observations made with the Mercator Telescope, operated on the island of La Palma by the Flemish Community, at the Spanish Observatorio del Roque de los Muchachos of the Instituto de Astrofísica de Canarias and TÜBİTAK National Observatory Russian-Turkish telescope operated at Saklıkent, Antalya
Endovascular aortic repair of a postdissecting thoracoabdominal aneurysm using intraoperative fusion imaging.

International audienceComputer-aided imaging can aid complex endovascular repair of aortic dissections in locating the narrow true lumen and identifying perfusion of visceral vessels by the true and/or false lumen. Although these anatomic data are available for analysis during planning, they are not readily available during the procedure with conventional imaging systems. We report the use of "fusion imaging" to facilitate the treatment of a postdissection thoracoabdominal aneurysm. The preoperative computer tomographic angiograms were processed, and the true and the false lumens were individually color labeled. These data were then superimposed on the fluoroscopic images in order to facilitate deployment of a fenestrated endograft
Joint distribution of the process and its sojourn time in a half-line $[a,+\infty)$ for pseudo-processes governed by higher-order heat-type equations

25 pagesInternational audienceLet $(X(t))_{t \ge 0}$ be the pseudo-process driven by the high-order heat-type equation $\frac{\partial u}{\partial t}=\pm \frac{\partial^N\!u}{\partial x^N}$, where $N$ is an integer greater than 2. We consider the sojourn time spent by $(X(t))_{t \ge 0}$ in $[a,+\infty)$ ($a\in \mathbb{R}$), up to a fixed time $t>0$: $T_a(t)=\int_0^t\ind_{[a,+\infty)}(X(s))\,\mathrm{d}s$. The purpose of this paper is to explicit the joint pseudo-distribution of the vector $(T_a(t),X(t))$ when the pseudo-process starts at a point $x\in \mathbb{R}$ at time $0$. The method consists in solving a boundary value problem satisfied by the Laplace transform of the aforementioned distribution
A silicate disk in the heart of the Ant

International audienceAims.We aim at getting high spatial resolution information on the dusty core of bipolar planetary nebulae to directly constrain the shaping process. Methods: We present observations of the dusty core of the extreme bipolar planetary nebula Menzel 3 (Mz 3, Hen 2-154, the Ant) taken with the mid-infrared interferometer MIDI/VLTI and the adaptive optics NACO/VLT. Results: The core of Mz 3 is clearly resolved with MIDI in the interferometric mode, whereas it is unresolved from the Ks to the N bands with single dish 8.2 m observations on a scale ranging from 60 to 250 mas. A striking dependence of the dust core size with the PA angle of the baselines is observed, that is highly suggestive of an edge-on disk whose major axis is perpendicular to the axis of the bipolar lobes. The MIDI spectrum and the visibilities of Mz 3 exhibit a clear signature of amorphous silicate, in contrast to the signatures of crystalline silicates detected in binary post-AGB systems, suggesting that the disk might be relatively young. We used radiative-transfer Monte Carlo simulations of a passive disk to constrain its geometrical and physical parameters. Its inclination (74° ± 3°) and position angle (5° ± 5°) are in accordance with the values derived from the study of the lobes. The inner radius is 9± 1 AU and the disk is relatively flat. The dust mass stored in the disk, estimated as 1 × 10-5~Mȯ, represents only a small fraction of the dust mass found in the lobes and might be a kind of relic of an essentially polar ejection process
Brand name to generic substitution of antiepileptic drugs does not lead to seizure-related hospitalization: a population-based case-crossover study

International audiencePurpose: There is still controversy on brand-to-generic (B-G) antiepileptic drugs (AEDs) substitution. Methods: To assess association between B-G AED substitution and seizure-related hospitalization, we designed a case crossover using the French National Health Insurance Database. We identified a cohort of adult patients who filled a prescription in 2009–2011 for AEDs with at least one brand name and one generic form. The outcome date was defined as the date of hospitalization, coded G40.x or G41.x, with a G40/G41 hospitalization-free period of at least 1 year. Patients with a medical history of cancer and women who gave birth in 2009–2011 were excluded. We required individuals to have regular dispensations of AEDs within the year preceding the outcome date. Free patients were defined as patients who had only brand name dispensations before the control period.Results: Eight thousand three hundred seventy nine patients (mean age ± standard deviation, 52.7 ± 18.8 years; sex ratio male/female, 1.27) were analyzed. Discordant pairs were 491 with B-G substitution in the control period only and 478 with B-G substitution in the case period only; odds ratio (95% confidence interval) 0.97 (0.86–1.10). No statistically significant interaction was detected among the four prespecified subgroup analyses (gender, age strata, free or non-free, and strict AED monotherapy or not). Controlling for non-seizure-related hospitalizations made no material difference. Sensitivity analyses yielded similar results.Conclusions: Brand-to-generic AED substitution was not associated with an elevated risk of seizure-related hospitalization
Non Incremental Transient Solution of the Rayleigh-Bénard Convection Model Using the PGD

International audienceThis paper focuses on the non-incremental solution of transient coupled non-linear models, in particular the one related to the Rayleigh-Benard flow problem that models natural thermal convection. For this purpose we are applying the so-called Proper Generalized Decomposition that proceeds by performing space-time separated representations of the different unknown fields involved by the flow model. This non-incremental solution strategy allows significant computational time savings and opens-new perspectives for introducing some flow and/or fluid parameters as extra-coordinates
Resolving the ancestry of Austronesian‑speaking populations

There are two very different interpretations of the prehistory of Island Southeast Asia (ISEA), with genetic evidence invoked in support of both. The "out-of-Taiwan" model proposes a major Late Holocene expansion of Neolithic Austronesian speakers from Taiwan. An alternative, proposing that Late Glacial/postglacial sea-level rises triggered largely autochthonous dispersals, accounts for some otherwise enigmatic genetic patterns, but fails to explain the Austronesian language dispersal. Combining mitochondrial DNA (mtDNA), Y-chromosome and genome-wide data, we performed the most comprehensive analysis of the region to date, obtaining highly consistent results across all three systems and allowing us to reconcile the models. We infer a primarily common ancestry for Taiwan/ISEA populations established before the Neolithic, but also detected clear signals of two minor Late Holocene migrations, probably representing Neolithic input from both Mainland Southeast Asia and South China, via Taiwan. This latter may therefore have mediated the Austronesian language dispersal, implying small-scale migration and language shift rather than large-scale expansion.This work was supported by FCT, the Portuguese
