The lived experience of sex integrated sport and the construction of athlete identity within the Olympic and Paralympic Equestrian disciplines

This is an Accepted Manuscript of an article published by Taylor & Francis in Sport in Society on 19 Oct 2015, available online: http://dx.doi.org/10.1080/17430437.2015.1096259.Equestrian sport is not subjected to the dominant binary sex segregation of most sports and therefore provides a unique opportunity to review how athlete ‘identity’ is constructed and framed within a sex integrated sporting experience. This research draws on an ethnographic evaluation of the Olympic and Paralympic experience of the British Equestrian Team. A total of 28 interviews were conducted with riders, performance managers and support staff with transcripts subjected to Ethnographic Content Analysis (ECA). Results show clear constructs of identity, such ‘them and us’, ‘horsey’, and ‘discipline specific’, with a noted absence of gender in the way interviewees describe themselves and others within the sport. Furthermore, in their accounts of their lives there is a lack of salience of gender with regards to their identity as sports persons. The paper considers the implications of this phenomenon for a claim that equestrian sport might be described from a participant’s perspective as gender neutral
Search for new phenomena with photon+jet events in proton-proton
  collisions at $\sqrt{s} = 13$ TeV with the ATLAS detector

A search is performed for the production of high-mass resonances decaying
into a photon and a jet in 3.2 fb$^{-1}$ of proton--proton collisions at a
centre-of-mass energy of $\sqrt{s} = 13$ TeV collected by the ATLAS detector at
the Large Hadron Collider. Selected events have an isolated photon and a jet,
each with transverse momentum above 150 GeV. No significant deviation of the
$\gamma+$jet invariant mass distribution from the background-only hypothesis is
found. Limits are set at 95% confidence level on the cross sections of generic
Gaussian-shaped signals and of a few benchmark phenomena beyond the Standard
Model: excited quarks with vector-like couplings to the Standard Model
particles, and non-thermal quantum black holes in two models of extra spatial
dimensions. The minimum excluded visible cross sections for Gaussian-shaped
resonances with width-to-mass ratios of 2% decrease from about 6 fb for a mass
of 1.5 TeV to about 0.8 fb for a mass of 5 TeV. The minimum excluded visible
cross sections for Gaussian-shaped resonances with width-to-mass ratios of 15%
decrease from about 50 fb for a mass of 1.5 TeV to about 1.0 fb for a mass of 5
TeV. Excited quarks are excluded below masses of 4.4 TeV, and non-thermal
quantum black holes are excluded below masses of 3.8 (6.2) TeV for
Randall--Sundrum (Arkani-Hamed--Dimopoulous--Dvali) models with one (six) extra
dimensions.Comment: 21 pages plus author list + cover pages (38 pages total), 5 figures.

Measurement of the $\phi \to \pi^0 e^+e^-$ transition form factor with
  the KLOE detector

A measurement of the vector to pseudoscalar conversion decay $\phi \to \pi^0
e^+e^-$ with the KLOE experiment is presented. A sample of $\sim 9500$ signal
events was selected from a data set of 1.7 fb$^{-1}$ of $e^+e^-$ collisions at
$\sqrt{s} \sim m_{\phi}$ collected at the DA$\Phi$NE $e^+e^-$ collider. These
events were used to obtain the first measurement of the transition form factor
$| F_{\phi \pi^0}(q^2) |$ and a new measurement of the branching ratio of the
decay: $\rm{BR}\,(\phi \to \pi^0 e^+e^-) = (\,1.35 \pm
0.05^{\,\,+0.05}_{\,\,-0.10}\,) \times 10 ^{-5}$. The result improves
significantly on previous measurements and is in agreement with theoretical
predictions.Comment: 13 pages, 4 figures; matches published versio
Impacts of Dreissena fouling on the physiological condition of native and non-native bivalves: interspecific and temporal variations

The impact of\ud
Dreissena\ud
fouling on unio-\ud
nids has hardly been studied in Europe, despite the fact\ud
that in some ecosystems (e.g. Lake Balaton, Hungary)\ud
infestations of several hundreds to a thousand indi-\ud
viduals per unionid have been observed. At present,\ud
the zebra mussel\ud
Dreissena polymorpha\ud
is a dominant\ud
species in Lake Balaton and in the last decade three\ud
other invasive bivalves were introduced, potentially\ud
increasing the pressure on native unionid survival. We\ud
examined whether the fouling of dreissenids (zebra\ud
and quagga (\ud
D. rostriformis bugensis\ud
) mussels) has a\ud
negative impact on native (\ud
Anodonta anatina\ud
,\ud
Unio\ud
pictorum\ud
and\ud
U. tumidus\ud
) and invasive (\ud
Corbicula\ud
fluminea\ud
and\ud
Sinanodonta woodiana\ud
) bivalves and\ud
whether there are any interspecific and temporal\ud
variations in fouling intensity and physiological\ud
condition measured by standard condition index and\ud
glycogen content. A significant negative impact was detected on native unionids only in July and Septem-\ud
ber (no impact was detected in May), when the fouling\ud
rate was high. For invasive species, a significant\ud
negative impact was detected on\ud
S. woodiana\ud
with a\ud
high level of dressenid infestation; whereas no signif-\ud
icant impact was detected on\ud
C. fluminea\ud
. Overall, this\ud
study confirms that\ud
Dreissena\ud
may threaten unionid\ud
species including the invasive\ud
S. woodiana\ud
, although\ud
high interspecific and temporal variations were\ud
observed. This situation should be taken into account\ud
in future ecological and conservational assessments\ud
because species respond differently to\ud
Dreissena\ud
fouling and effects seem to be more pronounced in\ud
late summer/early autumn. In addition, this study\ud
provides the first evidence that the invasive\ud
C.\ud
fluminea\ud
appear to be less vulnerable to dressenid\ud

Stress, psychosocial mediators and cognitive mediators in parents of child cancer patients and cancer survivors: Attention and working memory pathway perspectives

Objective: This review examines stress and its consequences on attention and working memory, stress symptoms in parents of child cancer patients and survivors and long term consequences of stress on cognitive processing in parents of child cancer survivors. Method: Eligible studies were experimental, meta-analyses and qualitative (2000–2013) from Pubmed, Medline, the Cochrane Library, PsycArticles and Google Scholar. Results: We identified 92 eligible papers. They showed that elevated stress can impede performances on tasks requiring attention and memory patterns. In paediatric oncology, parental stress increased shortly after diagnosis involving depression and anxiety. Consequences of stress on cognitive performances were observed mainly among depressed individuals. As regards parents of child cancer survivors, female gender, low SES, innate traits of anxiety/anger predicted the development of PTSS. Conclusion: Evidence of stress on attention and working memory processes in parents of child cancer survivors is insufficient developed.Peer reviewe
Contemporaneous observations of the radio galaxy NGC 1275 from radio to very high energy γ-rays

The radio galaxy NGC 1275, recently identified as a very high energy (VHE, >100 GeV) γ-ray emitter by MAGIC, is one of the few non-blazar active galactic nuclei detected in the VHE regime. The purpose of this work is to better understand the origin of the γ-ray emission and locate it within the galaxy. Methods: We studied contemporaneous multifrequency observations of NGC 1275 and modeled the overall spectral energy distribution. We analyzed unpublished MAGIC observations carried out between October 2009 and February 2010, and the previously published observations taken between August 2010 and February 2011. We studied the multiband variability and correlations by analyzing data of Fermi-LAT in the 100 MeV-100 GeV energy band, as well as Chandra (X-ray), KVA (optical), and MOJAVE (radio) data taken during the same period. Results: Using customized Monte Carlo simulations corresponding to early MAGIC stereoscopic data, we detect NGC 1275 also in the earlier MAGIC campaign. The flux level and energy spectra are similar to the results of the second campaign. The monthly light curve above 100 GeV shows a hint of variability at the 3.6σ level. In the Fermi-LAT band, both flux and spectral shape variabilities are reported. The optical light curve is also variable and shows a clear correlation with the γ-ray flux above 100 MeV. In radio, three compact components are resolved in the innermost part of the jet. One of these components shows a similar trend as the Fermi-LAT and KVA light curves. The γ-ray spectra measured simultaneously with MAGIC and Fermi-LAT from 100 MeV to 650 GeV can be well fitted either by a log-parabola or by a power-law with a subexponential cutoff for the two observation campaigns. A single-zone synchrotron-self-Compton model, with an electron spectrum following a power-law with an exponential cutoff, can explain the broadband spectral energy distribution and the multifrequency behavior of the source. However, this model suggests an untypical low bulk-Lorentz factor or a velocity alignment closer to the line of sight than the parsec-scale radio jet
Measurement of the production cross section ratio sigma(chi[b2](1P)) / sigma(chi[b1](1P)) in pp collisions at sqrt(s) = 8 TeV

A measurement of the production cross section ratio sigma(chi[b2](1P)) / sigma( chi[b1](1P)) is presented. The chi[b1](1P) and chi[b2](1P) bottomonium states, promptly produced in pp collisions at sqrt(s) = 8 TeV, are detected by the CMS experiment at the CERN LHC through their radiative decays chi[b1, 2](1P) to Upsilon(1S) + gamma. The emitted photons are measured through their conversion to electron- positron pairs, whose reconstruction allows the two states to be resolved. The Upsilon(1S) is measured through its decay to two muons. An event sample corresponding to an integrated luminosity of 20.7 inverse femtobarns is used to measure the cross section ratio in a phase-space region defined by the photon pseudorapidity, abs(eta[gamma]) &lt; 1.0 ; the Upsilon(1S) rapidity, abs(y[Upsilon]) &lt; 1.5 ; and the Upsilon(1S) transverse momentum, 7 &lt; pt[Upsilon] &lt; 40 GeV. The cross section ratio shows no significant dependence on the Upsilon(1S) transverse momentum, with a measured average value of 0.85 +/- 0.07 (stat+syst) +/- 0.08 (BF), where the first uncertainty is the combination of the experimental statistical and systematic uncertainties and the second is from the uncertainty in the ratio of the chi[b] branching fractions
Schrödinger geometries arising from Yang-Baxter deformations

Abstract: We present further examples of the correspondence between deformed AdS5×S5 solutions of type IIB supergravity and classical r-matrices satisfying the classical YangBaxter equation (CYBE). In the previous works, classical r-matrices have been composed of generators of only one of either so(2, 4) or so(6). In this paper, we consider some examples of r-matrices with both of them. The r-matrices of this kind contain (generalized) Schrödinger spacetimes and gravity duals of dipole theories. It is known that the generalized Schrödinger spacetimes can also be obtained via a certain class of TsT transformations called null Melvin twists. The metric and NS-NS two-form are reproduced by following the Yang-Baxter sigma-model description
Electroexcitation of the Δ+(1232) at low momentum transfer

International audienceWe report on new p(e,e′p)π∘p(e,e′p)π∘ measurements at the Δ+(1232)Δ+(1232) resonance at the low momentum transfer region, where the mesonic cloud dynamics is predicted to be dominant and rapidly changing, offering a test bed for chiral effective field theory calculations. The new data explore the Q2Q2 dependence of the resonant quadrupole amplitudes and for the first time indicate that the Electric and the Coulomb quadrupole amplitudes converge as Q2→0Q2→0. The measurements of the Coulomb quadrupole amplitude have been extended to the lowest momentum transfer ever reached, and suggest that more than half of its magnitude is attributed to the mesonic cloud in this region. The new data disagree with predictions of constituent quark models and are in reasonable agreement with dynamical calculations that include pion cloud effects, chiral effective field theory and lattice calculations. The measurements indicate that improvement is required to the theoretical calculations and provide valuable input that will allow their refinements
Measurement of the pseudorapidity and transverse momentum dependence of the elliptic flow of charged particles in lead-lead collisions at root s(NN)=2.76 TeV with the ATLAS detector

This Letter describes the measurement of elliptic flow of charged particles in lead-lead collisions at root s(NN) = 2.76 TeV using the ATLAS detector at the Large Hadron Collider (LHC). The results are based on an integrated luminosity of approximately 7 mu b(-1). Elliptic flow is measured over a wide region in pseudorapidity, vertical bar eta vertical bar < 2.5, and over a broad range in transverse momentum, 0.5 < p(T) < 20 GeV. The elliptic flow parameter nu(2) is obtained by correlating individual tracks with the event plane measured using energy deposited in the forward calorimeters. As a function of transverse momentum, nu(2)(p(T)) reaches a maximum at p(T) of about 3 GeV. then decreases and becomes weakly dependent on p(T) above 7-8 GeV. Over the measured pseudorapidity region, nu(2) is found to be only weakly dependent on eta, with less variation than observed at lower beam energies. The results are discussed in the context of previous measurements at lower collision energies, as well as recent results from the LHC
Evidence of amplitude modulation due to resonant mode coupling   in the δ Scuti star KIC 5892969
 : 
A particular or a general case?

International audienceA study of the star KIC 5892969 observed by the Kepler satellite is presented. Its three highest amplitude modes present a strong amplitude modulation. The aim of this work is to investigate amplitude variations in this star and their possible cause. Using the 4 years-long observations available, we obtained the frequency content of the full light curve. Then, we studied the amplitude and phase variations with time using shorter time stamps. The results obtained are compared with the predicted ones for resonant mode coupling of an unstable mode with lower frequency stable modes. Our conclusion is that resonant mode coupling is consistent as an amplitude limitation mechanism in several modes of KIC 5892969 and we discuss to which extent it might play an important role for other δ Scuti stars
H.E.S.S. discovery of VHE γ-rays from the quasar PKS 1510−089

International audienceThe quasar PKS 1510−089 (z = 0.361) was observed with the H.E.S.S. array of imaging atmospheric Cherenkov telescopes during high states in the optical and GeV bands, to search for very high energy (VHE, defined as E ≥ 0.1 TeV) emission. VHE γ-rays were detected with a statistical significance of 9.2 standard deviations in 15.8 h of H.E.S.S. data taken during March and April 2009. A VHE integral flux of I(0.15 TeV < E < 1.0 TeV)= (1.0 ± 0.2stat ± 0.2sys) × 10-11 cm-2 s-1 is measured. The best-fit power law to the VHE data has a photon index of Γ = 5.4 ± 0.7stat ± 0.3sys. The GeV and optical light curves show pronounced variability during the period of H.E.S.S. observations. However, there is insufficient evidence to claim statistically significant variability in the VHE data. Because of its relatively high redshift, the VHE flux from PKS 1510−089 should suffer considerable attenuation in the intergalactic space due to the extragalactic background light (EBL). Hence, the measured γ-ray spectrum is used to derive upper limits on the opacity due to EBL, which are found to be comparable with the previously derived limits from relatively-nearby BL Lac objects. Unlike typical VHE-detected blazars where the broadband spectrum is dominated by nonthermal radiation at all wavelengths, the quasar PKS 1510−089 has a bright thermal component in the optical to UV frequency band. Among all VHE detected blazars, PKS 1510−089 has the most luminous broad line region. The detection of VHE emission from this quasar indicates a low level of γ − γ absorption on the internal optical to UV photon field
Thermally-Stimulated Current Investigation of Dopant-Related D- and A+ Trap Centers in Germanium for Cryogenic Detector Applications

International audienceThermally-stimulated current measurements provide a sensitive tool to char-acterize carrier traps in germanium detectors for dark matter search. Using this technique at cryogenic temperatures, very shallow traps have been detected with binding energies of a fraction of a meV, associated with the dopant species in the D-(A+) charge states. A positive identification of these traps is achieved through an analysis of the field dependence of the carrier emission rates, which demonstrates a potential well for the trapped carriers in the form of a polarization well in r-4, consistent with Lax's model for carrier trapping by a neutral center. The density of these traps is assessed, and implications for the space-charge cancellation procedure in cryogenic Ge detectors are discussed
The molecular gas reservoir of 6 low-metallicity galaxies from the Herschel Dwarf Galaxy Survey : A ground-based follow-up survey of CO(1–0), CO(2–1), and CO(3–2)

International audienceContext. Observations of nearby starburst and spiral galaxies have revealed that molecular gas is the driver of star formation. However, some nearby low-metallicity dwarf galaxies are actively forming stars, but CO, the most common tracer of this reservoir, is faint, leaving us with a puzzle about how star formation proceeds in these environments. Aims. We aim to quantify the molecular gas reservoir in a subset of 6 galaxies from the Herschel Dwarf Galaxy Survey with newly acquired CO data and to link this reservoir to the observed star formation activity. Methods. We present CO(1–0), CO(2–1), and CO(3–2) observations obtained at the ATNF Mopra 22-m, APEX, and IRAM 30-m telescopes, as well as [C ii] 157μm and [O i] 63μm observations obtained with the Herschel/PACS spectrometer in the 6 low-metallicity dwarf galaxies: Haro 11, Mrk 1089, Mrk 930, NGC 4861, NGC 625, and UM 311. We derived their molecular gas masses from several methods, including using the CO-to-H2 conversion factor XCO (both Galactic and metallicity-scaled values) and dust measurements. The molecular and atomic gas reservoirs were compared to the star formation activity. We also constrained the physical conditions of the molecular clouds using the non-LTE code RADEX and the spectral synthesis code Cloudy. Results. We detect CO in 5 of the 6 galaxies, including first detections in Haro 11 (Z ~ 0.4 Z⊙), Mrk 930 (0.2 Z⊙), and UM 311 (0.5 Z⊙), but CO remains undetected in NGC 4861 (0.2 Z⊙). The CO luminosities are low, while [C ii] is bright in these galaxies, resulting in [C ii]/CO(1–0) ≥ 10 000. Our dwarf galaxies are in relatively good agreement with the Schmidt-Kennicutt relation for total gas. They show short molecular depletion timescales, even when considering metallicity-scaled XCO factors. Those galaxies are dominated by their H i gas, except Haro 11, which has high star formation efficiency and is dominated by ionized and molecular gas. We determine the mass of each ISM phase in Haro 11 using Cloudy and estimate an equivalent XCO factor that is 10 times higher than the Galactic value. Overall, our results confirm the emerging picture that CO suffers from significant selective photodissociation in low-metallicity dwarf galaxies
Evidence of triggered star formation in G327.3-0.6. Dust-continuum mapping of an infrared dark cloud with P-ArTéMiS

4 pagesInternational audienceAims. Expanding HII regions and propagating shocks are common in the environment of young high-mass star-forming complexes. They can compress a pre-existing molecular cloud and trigger the formation of dense cores. We investigate whether these phenomena can explain the formation of high-mass protostars within an infrared dark cloud located at the position of G327.3-0.6 in the Galactic plane, in between two large infrared bubbles and two HII regions. Methods: The region of G327.3-0.6 was imaged at 450 μ m with the CEA P-ArTéMiS bolometer array on the Atacama Pathfinder EXperiment telescope in Chile. APEX/LABOCA and APEX-2A, and Spitzer/IRAC and MIPS archives data were used in this study. Results: Ten massive cores were detected in the P-ArTéMiS image, embedded within the infrared dark cloud seen in absorption at both 8 and 24 μm. Their luminosities and masses indicate that they form high-mass stars. The kinematical study of the region suggests that the infrared bubbles expand toward the infrared dark cloud. Conclusions: Under the influence of expanding bubbles, star formation occurs in the infrared dark areas at the border of HII regions and infrared bubbles
Search for the production of an excited bottom quark decaying to tW in proton-proton collisions at sqrt(s) = 8 TeV

A search is presented for a singly produced excited bottom quark (b*) decaying to a top quark and a W boson in the all-hadronic, lepton+jets, and dilepton final states in proton-proton collisions at s√=8 TeV recorded by the CMS experiment at the CERN LHC. Data corresponding to an integrated luminosity of 19.7 fb−1 are used. No significant excess of events is observed with respect to standard model expectations. We set limits at 95% confidence on the product of the b* quark production cross section and its branching fraction to tW. The cross section limits are interpreted for scenarios including left-handed, right-handed, and vector-like couplings of the b* quark and are presented in the two-dimensional coupling plane based on the production and decay coupling constants. The masses of the left-handed, right-handed, and vector-like b* quark states are excluded at 95% confidence below 1390, 1430, and 1530 GeV, respectively, for benchmark couplings. This analysis gives the most stringent limits on the mass of the b∗ quark to date
Drug-eluting balloons for the treatment of the superficial femoral artery in-stent restenosis: 2-year follow-up.

OBJECTIVES: \ud
\ud
The aim of this prospective registry was to evaluate the safety and efficacy at 2-year follow-up of the use of drug-eluting balloons (DEBs) for the treatment of superficial femoral artery (SFA) in-stent restenosis (ISR).\ud
\ud
BACKGROUND: \ud
\ud
The use of DEBs for the treatment of SFA ISR is associated with a satisfactory primary patency rate at 1 year, but no data are available for longer follow-up. Unfortunately, when DEBs were used to treat SFA de novo lesions, the occurrence of restenosis increased by 50% between the first and the second years of follow-up.\ud
\ud
METHODS: \ud
\ud
From December 2009 to December 2010, 39 consecutive patients underwent percutaneous transluminal angioplasty of SFA ISR at our institution (Clinica Montevergine, Mercogliano, Italy). All patients underwent conventional SFA percutaneous transluminal angioplasty and final post-dilation with paclitaxel-eluting balloons (IN.PACT, Medtronic Inc., Minneapolis, Minnesota). Patients were evaluated for up to 24 months.\ud
\ud
RESULTS: \ud
\ud
During follow-up, 1 patient died of heart failure and another of sudden death, for a 2-years rate of cardiovascular mortality rate of 5.12 %. The primary patency rate at 2 years was 70.3% (11 of 37 patients experienced restenosis recurrence at 2-year follow-up). The treatment of complex ISR lesions (classes II and III) was associated with an increased rate of recurrent restenosis compared with class I (33.3 % and 36.3 % vs. 12.5%; p = 0.05).\ud
\ud
CONCLUSIONS: \ud
\ud
The data suggest that adjunctive use of DEBs for the treatment of SFA ISR is a safe and effective therapeutic strategy up to 2 years of follow-up
