This article is open access.To study contemporary popliteal artery aneurysm (PA) repair.Vascunet is a collaboration of population-based registries in 10 countries: eight had data on PA repair (Australia, Finland, Hungary, Iceland, New Zealand, Norway, Sweden, and Switzerland).From January 2009 until June 2012, 1,471 PA repairs were registered. There were 9.59 operations per million person years, varying from 3.4 in Hungary to 17.6 in Sweden. Median age was 70 years, ranging from 66 years in Switzerland and Iceland to 74 years in Australia and New Zealand; 95.6% were men and 44% were active smokers. Elective surgery dominated, comprising 72% of all cases, but only 26.2% in Hungary and 39.7% in Finland, (p < .0001). The proportion of endovascular PA repair was 22.2%, varying from 34.7% in Australia, to zero in Switzerland, Finland, and Iceland (p < .0001). Endovascular repair was performed in 12.2% of patients with acute thrombosis and 24.1% of elective cases (p < .0001). A vein graft was used in 87.2% of open repairs, a synthetic or composite graft in 12.7%. Follow-up was until discharge or 30 days. Amputation rate was 2.0% overall: 6.5% after acute thrombosis, 1.0% after endovascular, 1.8% after open repair, and 26.3% after hybrid repair (p < .0001). Mortality was 0.7% overall: 0.1% after elective repair, 1.6% after acute thrombosis, and 11.1% after rupture.Great variability between countries in incidence of operations, indications for surgery, and choice of surgical technique was found, possibly a result of surgical tradition rather than differences in case mix. Comparative studies with longer follow-up data are warranted
GLOGOS, A New Global Onshore Gas-Oil Seeps Dataset

Petroleum seeps have historically been important drivers of global petroleum exploration. Still today they can serve as direct indicators of gas and/or
oil subsurface accumulations. In particular the assessment of the origin of seeping gas is a key task for understanding, without drilling, the subsurface
hydrocarbon potential, genesis and quality; e.g., the presence of shallow microbial gas, deeper thermogenic accumulations, the presence of oil and
non-hydrocarbon undesirable gases (CO2, N2, H2S). Seeps are then indicators of tectonic discontinuities (faults) and fractured rocks; they can also
represent geo-hazards and sources of greenhouse gas (methane) and photochemical pollutants (ethane and propane).
A new global dataset of onshore gas and oil seeps (GLOGOS) is here presented. GLOGOS includes more than 1150 seeps from 84 countries (version
August 2009), and it is continuously updated and expanded. The dataset includes geographical and gas-geochemical data (molecular and isotopic
composition of the main gases). Many seeps are recently discovered or never reported in other databases. Seeps are catalogued by country and
classified in three types: gas seeps, oil seeps and mud volcanoes. All seeps have a bibliographic or www reference. GLOGOS is a unique tool for
hydrocarbon exploration, assessment of Total Petroleum Systems and geo- structural studies
Articulating an Indian diaspora in South Africa : The Consulate General of India, diaspora associations and practices of collaboration

Engagements between sending states and their diasporas have come under increasing critical scrutiny. Whilst political geographers have driven critical analysis of national level policies, debates have largely overlooked the broader range of actors, transactions and practices involved in implementing national policies in a geohistorically diverse array of diasporic contexts and settings. Over the last decade, the Indian government has invested significant resources in overseas diplomatic missions, consulates and high commissions to administer its diaspora outreach strategies. This paper examines the role of the Consulate General of India (CGI) in Durban, South Africa, focusing in particular on the networks of agents, associations, groups and political actors involved in collaborating with the CGI Durban in diaspora outreach practices. This paper draws on two periods of fieldwork in Durban between 2004 and 2005 and was supplemented by ongoing visual and textual analysis of news articles, promotional material, reports and websites. Using the concept of articulation, the paper highlights the discursive and performative practices involved in bringing together the agendas of the GOI with those of South African Indian diaspora associations through the outreach practices of the CGI in Durban. It argues that articulatory practices are essential to resolving some of the subjective and embodied dilemmas and contestations of belonging inherent in South African Indians’ participation in diaspora outreach initiatives. Investigating how articulation contributes to drawing diverse and even competing agendas together makes room for further understanding the ways in which diaspora outreach practices can travel across a wide network, and the diverse agencies that can become catalysed in the process.Peer-reviewedPublisher Versio
Moving beyond standard procedures to assess spontaneous recognition memory.

This review will consider how spontaneous tasks have been applied alongside neuroscientific techniques to test complex forms of recognition memory for objects and their environmental features, e.g. the spatial location of an object or the context in which it is presented. We discuss studies that investigate the roles of the perirhinal cortex and the hippocampus in recognition memory using standard testing paradigms, and consider how these findings contribute to the ongoing debate about whether recognition memory is a single unitary process or multiple processes that can be dissociated anatomically and functionally. Due to the wide use of spontaneous tasks, the need for improved procedures that reduce animal use is acknowledged, with multiple trial paradigms discussed as a novel way of reducing variability and animal numbers in these tasks. The importance of improving translation of animal models to humans is highlighted, with emphasis on a shift away from relying on the phenomenological experience of human subjects
Strontium isotope evidence of early Funnel Beaker Culture movement of cattle.

The movement of livestock across and within landscapes is increasingly being recognized as common in northern European prehistoric contexts, and was performed for various purposes. However, almost nothing is known about the movement of livestock in the earliest phase of the southern Scandinavian Neolithic Funnel Beaker Culture (ENI, TRB, 4000–3500 cal BC), or even if such movement is indicated. In this study, domestic cattle (Bos taurus) teeth from the early Neolithic sites Almhov, Sweden (N = 6) and Havnelev, Denmark (N = 7) were analyzed in order to determine the presence and character of potential livestock movement in this period. Tooth enamel strontium isotope analyses indicated a range of variation in local origin of the animals: some probably local and some non-local. Importantly, both sites yielded an individual exhibiting strontium isotope ratios indicating movement from elsewhere and over a body of water via boat. Although based on a small number of cattle, the movement of livestock is indicated in the earliest Neolithic in the region and provides evidence of social, economic, or other connections over substantial distances
Interface model between the bioreactor and the membrane in a membrane bioreactor for wastewater treatment.

This paper proposes a structure of an integrated mathematical model of a membrane bioreactor (MBR) and describes the links between two main parts of a MBR model: the bioreactor and the membrane. In case of an immersed MBR three types of links are\ud
considered: a relationship between specific cake resistance (SCR) and extracellular polymeric substances (EPS) in the bioreactor, a relationship between air scour rate and shear stresses on the membrane surface, and a relationship between concentration of\ud
soluble microbial products (SMP) in the bioreactor and rate of pore constriction. While SMP concentration features directly in the equations of pore constriction, EPS are assumed to affect SCR which in turn has an effect on cake filtration. The relationship\ud
between EPS and SCR is described with a linear algebraic equation. Shear stresses on the membrane surface are calculated as a function of air scour rate with a one- imensional slug flow model
Aircraft-based observations of air–sea turbulent ﬂuxes around the British Isles

Observations of turbulent ﬂuxes of momentum, heat and moisture from low-level aircraft data are presented. Fluxes are calculated using the eddy covariance technique from ﬂight legs typically ∼40 m above the sea surface. Over 400 runs of 2 min (∼12 km) from 26 ﬂights are evaluated. Flight legs are mainly from around the British Isles although a small number are from around Iceland and Norway. Sea-surface temperature (SST) observations from two on-board sensors (the ARIES interferometer and a Heimann radiometer) and a satellite-based analysis (OSTIA) are used to determine an improved SST estimate. Most of the observations are from moderate to strong wind speed conditions, the latter being a regime short of validation data for the bulk ﬂux algorithms that are necessary for numerical weather prediction and climate models. Observations from both statically stable and unstable atmospheric boundary-layer conditions are presented. There is a particular focus on several ﬂights made as part of the DIAMET (Diabatic inﬂuence on mesoscale structures in extratropical storms) project.\ud
Observed neutral exchange coefﬁcients are in the same range as previous studies, although higher for the momentum coefﬁcient, and are broadly consistent with the COARE 3.0 bulk ﬂux algorithm, as well as the surface exchange schemes used in the ECMWF and Met Ofﬁce models. Examining the results as a function of aircraft heading shows higher ﬂuxes and exchange coefﬁcients in the across-wind direction, compared to along-wind (although this comparison is limited by the relatively small number of along-wind legs). A multi-resolution spectral decomposition technique demonstrates a lengthening of spatial scales in along-wind variances in along-wind legs, implying the boundary-layer eddies are elongated in the along-wind direction. The along-wind runs may not be able to adequately capture the full range of turbulent exchange that is occurring because elongation places the largest eddies outside of the run length
The fate of the Higgs vacuum

We have recently suggested that tiny black holes can act as nucleation seeds
for the decay of the metastable Higgs vacuum. Previous results applied only to
the nucleation of thin-wall bubbles, and covered a very small region of
parameter space. This paper considers bubbles of arbitrary profile and reaches
the same conclusion: black holes seed rapid vacuum decay. Seeded and unseeded
nucleation rates are compared, and the gravitational back reaction of the
bubbles is taken into account. The evolution of the bubble interior is
described for the unseeded nucleation. Results are presented for the
renormalisation group improved Standard Model Higgs potential, and a simple
effective model representing new physics.Comment: 21 pages, 10 figure
$N^{\bf *}$ decays to $N\omega$ from new data on $\gamma p\to \omega p$

Data on the reaction $\gamma p\to \omega p$ with $\omega\to\pi^0\gamma$,
taken with unpolarized or polarized beams in combination with an unpolarized or
polarized proton-target, were analyzed within the Bonn-Gatchina (BnGa) partial
wave analysis. Differential cross sections, several spin density matrix
elements, the beam asymmetry $\Sigma$, the normalized helicity difference $E$,
and the correlation $G$ between linear photon and longitudinal target
polarization were included in a large data base on pion and photo-induced
reactions. The data on $\omega$ photoproduction are used to determine twelve
$N^*\to N\omega$ branching ratios; most of these are determined for the first
time.Comment: 6 pages, 4 figures, 2 table
Supergravity background of lambda-deformed model for AdS2 x S2
  supercoset

Starting with the F/G supercoset model corresponding to the AdS_n x S^n
superstring one can define the lambda-model of arXiv:1409.1538 either as a
deformation of the F/F gauged WZW model or as an integrable one-parameter
generalization of the non-abelian T-dual of the AdS_n x S^n superstring sigma
model with respect to the whole supergroup F. Here we consider the case of n=2
and find the explicit form of the 4d target space background for the
lambda-model for the PSU(1,1|2)/[SO(1,1) x SO(2)] supercoset. We show that this
background represents a solution of type IIB 10d supergravity compactified on a
6-torus with only metric, dilaton Phi and the RR 5-form (represented by a
2-form F in 4d) being non-trivial. This implies that the lambda-model is Weyl
invariant at the quantum level and thus defines a consistent superstring sigma
model. The supergravity solution we find is different from the one in
arXiv:1410.1886 which should correspond to a version of the lambda-model where
only the bosonic subgroup of F is gauged. Still, the two solutions have
equivalent scaling limit of arXiv:1504.07213 leading to the isometric
background for the metric and e^Phi F which is related to the eta-deformed
AdS_2 x S^2 sigma model of arXiv:1309.5850. Similar results are expected in the
AdS_3 x S^3 and AdS_5 x S^5 cases.Comment: 31 pages; v2: minor misprints correcte
ISC-GEM: Global Instrumental Earthquake Catalogue (1900–2009), II. Location and seismicity patterns

Abstract We present the final results of a two-year project sponsored by the Global Earthquake Model (GEM) Foundation. The ISC-GEM global catalogue consists of some 19 thousand instrumentally recorded, moderate to large earthquakes, spanning 110 years of seismicity. We relocated all events in the catalogue using a two-tier approach. The EHB location methodology (Engdahl et al., 1998) was applied first to obtain improved hypocentres with special focus on the depth determination. The locations were further refined in the next step by fixing the depths to those from the EHB analysis and applying the new International Seismological Centre (ISC) location algorithm (Bondár and Storchak, 2011) that reduces location bias by accounting for correlated travel-time prediction error structure. To facilitate the relocation effort, some one million seismic P and S wave arrival-time data were added to the ISC database for the period between 1904 and 1970, either from original station bulletins in the ISC archive or by digitizing the scanned images of the International Seismological Summary (ISS) bulletin (Villaseñor and Engdahl, 2005, 2007). Although no substantial amount of new phase data were acquired for the modern period (1964–2009), the number of phases used in the location has still increased by three millions, owing to fact that both the EHB and ISC locators use most well-recorded ak135 (Kennett et al., 1995) phases in the location. We show that the relocation effort yielded substantially improved locations, especially in the first half of the 20th century; we demonstrate significant improvements in focal depth estimates in subduction zones and other seismically active regions; and we show that the ISC-GEM catalogue provides an improved view of 110 years of global seismicity of the Earth. The ISC-GEM Global Instrumental Earthquake Catalogue represents the final product of one of the ten global components in the GEM program, and is available to researchers at the ISC (www.isc.ac.uk) website
Cold asymmetrical fermion superfluids in nonperturbative renormalisation group

The application of the nonperturbative renormalisation group approach to a system with two fermion species is studied. Assuming a simple ansatz for the effective action with effective bosons, describing pairing effects we derive a set of approximate flow equations for the effective coupling including boson and fermionic fluctuations. The case of two fermions with different masses but coinciding Fermi surfaces is considered. The phase transition to a phase with broken symmetry is found at a critical value of the running scale. The large mass difference is found to disfavour the formation of pairs. The mean-field results are recovered if the effects of boson loops are omitted. While the boson fluctuation effects were found to be negligible for large values of $p_{F} a$ they become increasingly important with decreasing $p_{F} a$ thus making the mean field description less accurate
K+ Lambda and K+ Sigma(0) photoproduction with fine center-of-mass energy resolution

Measurements of gamma p -&gt; K+ Lambda and gamma p -&gt; K+ Sigma(0) cross-sections have been obtained with the photon tagging facility and the Crystal Ball calorimeter at MAMI-C. The measurement uses a novel K+ meson identification technique in which the weak decay products are characterized using the energy and timing characteristics of the energy deposit in the calorimeter, a method that has the potential to be applied at many other facilities. The fine center-of-mass energy (W) resolution and statistical accuracy of the new data results in a significant impact on partial wave analyses aiming to better establish the excitation spectrum of the nucleon. The new analyses disfavor a strong role for quark-diquark dynamics in the nucleon
Search for supersymmetry in pp collisions at √s = 8 TeV in events with a single lepton, large jet multiplicity, and multiple b jets

Results are reported from a search for supersymmetry in pp collisions at a center-of- mass energy of 8 TeV, based on events with a single isolated lepton (electron or muon) and multiple jets, at least two of which are identified as b jets. The data sample corresponds to an integrated luminosity of 19.3 fb−1recorded by the CMS experiment at the LHC in 2012. The search is motivated by supersymmetric models that involve strong-production processes and cascade decays of new particles. The resulting final states contain multiple jets as well as missing transverse momentum from weakly interacting particles. The event yields, observed across several kinematic regions, are consistent with the expectations from standard model processes. The results are interpreted in the context of simplified supersymmetric scenarios with pair production of gluinos, where each gluino decays to a top quark–antiquark pair and the lightest neutralino. For the case of decays via virtual top squarks, gluinos with a mass smaller than 1.26 TeV are excluded for low neutralino masses
Comorbidities with Posttraumatic Stress Disorder (PTSD) among combat veterans : 15 years postwar analysis

The aim of this study was to investigate the differences in the prevalence of somatic diseases among combat veterans and their contemporaries who were not exposed to the traumatic experience at the battlefield, and to determine whether socio-demographic factors, exposure to war-time trauma and/or injury might predict individual somatic diseases. The study included 1, 558 subjects living in south Croatia: 501 male combat veterans with posttraumatic stress disorder (PTSD) and the corresponding control group of 825 men who were not exposed to combat experience. Veterans with PTSD, regardless of the length of time spent in war, suffered more often from cardiovascular, dermatological, musculoskeletal, pulmonary and metabolic diseases than corresponding control subjects who were not exposed to combat experience. The predictors of cardiovascular, musculoskeletal and malignant diseases in veterans were age, length of time spent in combat, having been wounded. A longer period in the combat zone was associated with arrhythmias in veterans with PTSD complicated with other psychiatric comorbidities. PTSD as a result of exposure to war trauma increases the possibility of developing somatic diseases
Cathodoluminescence microscopy of superconducting and non-superconducting Tl2Ba2CuO6+x polycrystals

International audienceLuminescence properties of Tl2Ba2CuO6+x samples with different superconducting transition temperatures have been studied by cathodoluminescence (CL) in the scanning electron microscope. Independent of the crystal structure, tetragonal or orthorhombic, the CL spectra show two resolved bands at about 430 nm (2.9 eV) and 540 nm (2.3 eV), respectively. The results show that the 2.3 eV emission is related to oxygen content and is more intense in low-oxygen content superconducting samples. It is proposed that this band is related to a complex center involving oxygen vacancies. A comparison of spectra from Tl2Ba2CuO6+x and from precursors used in the synthesis (CuOx, Tl2Ba205) has been carried out
The "Mother of All Puzzles" at thirty: a meta-analysis

International audienceThis paper provides a meta-analysis of 1651 point estimates of Feldstein and Horioka saving retention coefficient from 49 peer-reviewed papers published over three decades. We get two main results. First, correcting for publication bias, we find a consistent underlying coefficient lying between 0.56 and 0.67 for studies using the original paper. Second, heterogeneity reported in the estimates of the Feldstein and Horioka can be explained by a few main factors. In particular, we find evidence that the saving retention coefficient is systematically underestimated with models written in first difference, models using the saving ratio or the current account ratio as the dependent variable instead of the investment ratio, and models including indicators of the public deficit or indicators of the country size as additional explanatory variables
Coupled measurements of δ^18O and δD of hydration water and salinity of fluid inclusions in gypsum from the Messinian Yesares Member, Sorbas Basin (SE Spain)

We studied one cycle (Cycle 6) of gypsum–marl deposition from the Messinian Yesares Member in Sorbas Basin, Spain. The objective was to reconstruct the changing environment of deposition and its relation to astronomically-forced climate change. The δ18O and δD of gypsum hydration water (CaSO4 • 2H2O) and salinity of fluid inclusions were measured in the same samples to test if they record the composition of the mother fluid from which gypsum was precipitated. Water isotopes are highly correlated with fluid inclusion salinity suggesting the hydration water has not exchanged after formation. The relatively low water isotope values and fluid inclusion salinities indicate a significant influence of meteoric water, whereas δ34S, δ18OSO4 and 87Sr/86Sr support a dominant marine origin for the gypsum deposits. The discrepancy between water and elemental isotope signatures can be reconciled if meteoric water dissolved previously deposited marine sulfates supplying calcium and sulfate ions to the basin which maintained gypsum saturation. This recycling process accounts for the marine δ34S, δ18OSO4 and 87Sr/86Sr signatures, whereas the low δ18O and δD values of gypsum hydration water and fluid inclusion salinities reflect the influence of freshwater
