An ice-sheet scale comparison of eskers with modelled subglacial drainage routes

This paper was accepted for publication in the journal Geomorphology and the definitive published version is available at http://dx.doi.org/10.1016/j.geomorph.2015.06.016Eskers record a time-integrated signature of channelised meltwater drainage during\ud
deglaciation providing vital information on the nature and evolution of subglacial drainage. In this\ud
paper, we compare the spatial pattern of eskers beneath the former Laurentide Ice Sheet with\ud
subglacial drainage routes diagnosed at discrete time intervals from the results of a numerical icesheet\ud
model. Perhaps surprisingly, we show that eskers predominantly occur in regions where\ud
modelled subglacial water flow is low. Eskers and modelled subglacial drainage routes were found to\ud
typically match for lengths <10 km, and most eskers show a better agreement with the routes close to\ud
the ice margin just prior to deglaciation. This supports a time-transgressive esker pattern, with\ud
formation in short (<10 km) segments of conduit close behind a retreating ice margin, and probably\ud
associated with thin, stagnant or sluggish ice. Esker forming conduits were probably dominated by\ud
supraglacially fed meltwater inputs. We also show that modelled subglacial drainage routes containing\ud
the largest concentrations of meltwater show a close correlation with palaeo-ice stream locations. The\ud
paucity of eskers along the terrestrial portion of these palaeo-ice streams and meltwater routes is\ud
probably due to the prevalence of distributed drainage and the high erosion potential of fast-flowing\ud
ice
Association between participation in outdoor play and sport at 10 years old with physical activity in adulthood

This is an open access article under the CC BY-NC-ND license\ud
(http://creativecommons.org/licenses/by-nc-nd/4.0/).Objective. This study aimed to investigate whether active outdoor play and/or sports at age 10 is associated\ud
with sport/physical activity at 32 year follow-up using a birth cohort study.\ud
Methods. Data were from the 1970 British Cohort Study, a longitudinal observational study. The present paper\ud
included data from the age 10 years and age 42 years surveys. At age 10 the participant's mother provided information\ud
regarding how often their child played sports, and played outside on streets, parks or playgrounds. At age\ud
42 participants reported frequency of participation in physical activities and sports. Associations between participation\ud
in sport/active outdoor play at age 10 years and adult sport/physical activity were investigated using adjusted\ud
(gender, fathers socio-occupational class, child's BMI, father's BMI, self-rated health at age 42, assessment\ud
of own weight at age 42, participant's education) Cox regression.\ud
Results. Final adjusted Cox regression models showed that participants (n = 6458) who often participated in\ud
sports at age 10 were significantly more likely to participate in sport/physical activity at age 42 (RR 1.10; 95% CI\ud
1.01 to 1.19). Active outdoor play at age 10 was not associated with participation in sport/physical activity at age\ud
42 (RR 0.99; 95% CI 0.91 to 1.07).\ud
Conclusion. Childhood activity interventions might best achieve lasting change by promoting engagement in\ud
sport rather than active outdoor play
Gravitational torques imply molecular gas inflow towards the nucleus of
  M51

The transport of gas towards the centre of galaxies is critical for black
hole feeding and, indirectly, it can control active galactic nucleus (AGN)
feedback. We have quantified the molecular gas inflow in the central R<1kpc of
M51 to be 1 Msun/yr, using a new gravitational torque map and the molecular gas
traced by the PdBI Arcsecond Whirlpool Survey (PAWS). The nuclear stellar bar
is responsible for this gas inflow. We have also used torque profiles to
estimate the location of dynamical resonances, suggesting a corotation for the
bar at R~20", and a corotation for the spiral at R~100". We demonstrate how
important it is to correct 3.6um images for dust emission in order to compute
gravitational torques, and we carefully examine further sources of uncertainty.
Our observational measurement of gas inflow can be compared with nuclear
molecular outflow rates and provide useful constraints for numerical
simulations.Comment: 19 pages, 12 figures. Accepted by A&
Pentaquark states in a diquark-triquark model

The diquark-triquark model is used to explain charmonium-pentaquark states,
i.e., $P_c(4380)$ and $P_c(4450)$, which were observed recently by the LHCb
collaboration. For the first time, we investigate the properties of the color
attractive configuration of a triquark and we define a nonlocal light cone
distribution amplitude for pentaquark states, where both diquark and triquark
are not pointlike, but they have nonzero size. We establish an effective
diquark-triquark Hamiltonian based on spin-orbital interaction. According to
the Hamiltonian, we show that the minimum mass splitting between
$\frac{5}{2}^+$ and $\frac{3}{2}^-$ is around $100$~MeV, which may naturally
solve the challenging problem of small mass splitting between $P_c(4450)$ and
$P_c(4380)$. This helps to understand the peculiarities of $P_c(4380)$ with a
broad decay width whereas $P_c(4450)$ has a narrow decay width. Based on the
diquark-triquark model, we predict more pentaquark states, which will hopefully
be measured in future experiments.Comment: 7 pages, 3 figures, 1 table; matches the version accepted in

Study of Z boson production in pPb collisions at sqrt(s[NN]) = 5.02 TeV

The production of Z bosons in pPb collisions at sqrt(s[NN]) = 5.02 TeV is
studied by the CMS experiment via the electron and muon decay channels. The
inclusive cross section is compared to pp collision predictions, and found to
scale with the number of elementary nucleon-nucleon collisions. The
differential cross sections as a function of the Z boson rapidity and
transverse momentum are measured. Though they are found to be consistent within
uncertainty with theoretical predictions both with and without nuclear effects,
the forward-backward asymmetry suggests the presence of nuclear effects at
large rapidities. These results provide new data for constraining nuclear
parton distribution functions.Comment: Replaced with published version. Added the journal reference and DOI.

Evidence for exclusive gamma gamma to W+W- production and constraints on
  anomalous quartic gauge couplings in pp collisions at sqrt(s) = 7 and 8 TeV

A search for exclusive or quasi-exclusive gamma gamma to W+W- production, via
pp to p(*) W+W- p(*) to p(*) mu+/- e-/+ at sqrt(s) = 8 TeV, is reported using
data corresponding to an integrated luminosity of 19.7 inverse femtobarns.
Events are selected by requiring the presence of an electron-muon pair with
large transverse momentum pt(mu+/- e-/+) > 30 GeV, and no associated charged
particles detected from the same vertex. The 8 TeV results are combined with
the previous 7 TeV results (obtained for 5.05 inverse femtobarns of data). In
the signal region, 13 (2) events are observed over an expected background of
3.9 +/- 0.6 (0.84 +/-0.15) events for 8 (7) TeV, resulting in a combined excess
of 3.4 standard deviations over the background-only hypothesis. The observed
yields and kinematic distributions are compatible with the standard model
prediction for exclusive and quasi-exclusive gamma gamma to W+W- production.
Upper limits on the anomalous quartic gauge coupling operators a[W;0,C]
(dimension-6) and f[M0,1,2,3] (dimension-8), the most stringent to date, are
derived from the measured dilepton transverse momentum spectrum.Comment: Replaced with published version. Added the journal reference and DOI.

Effects of Nuclear Potential on the Cumulants of Net-Proton and
  Net-Baryon Multiplicity Distributions in Au+Au Collisions at
  $\sqrt{s_{\text{NN}}} = 5\,\text{GeV}$

We analyze the rapidity and transverse momentum dependence for the cumulants
of the net-proton and net-baryon distributions in Au+Au collisions at
$\sqrt{s_{\text{NN}}} = 5\,\text{GeV}$ with a microscopic hadronic transport
(JAM) model. To study the effects of mean field potential and softening of
equation of state (EoS) on the fluctuations of net-proton (baryon) in heavy-ion
collisions, the calculations are performed with two different modes. The
softening of EoS is realized in the model by implementing the attractive orbit
in the two-body scattering to introduce a reduction pressure of the system. By
comparing the results from the two modes with the results from default cascade,
we find the mean field potential and softening of EoS have strong impacts on
the rapidity distributions ($\text{d}N/\text{d}y$) and the shape of the
net-proton (baryon) multiplicity distributions. The net-proton (baryon)
cumulants and their ratios calculated from all of the three modes are with
similar trends and show significant suppression with respect to unity, which
can be explained by the presence of baryon number conservations. It indicates
that the effects of mean field potential and softening of EoS might be not the
ingredients that are responsible to the observed strong enhancement in the most
central Au+Au collisions at 7.7 GeV measured by the STAR experiment at RHIC.Comment: 6 pages, 5 figure
Association of urinary biomarker COLL2-1NO-2 with incident clinical and radiographic knee OA in overweight and obese women

__Objective:__ To investigate the association between urinary biomarker Coll2-1NO<inf>2</inf> (uColl2-1NO<inf>2</inf>) and incident knee OA after 2.5 years follow-up in middle-aged overweight and obese women at high risk for knee osteoarthritis (OA).  \ud
__Design:__ Data were used from PROOF, a randomized controlled trial with 2.5 years follow-up evaluating the preventive effects of a diet and exercise program and oral glucosamine sulphate (double blind and placebo controlled), on development of incident knee OA in women with body mass index≥27kg/m<sup>2</sup> without signs of knee OA at baseline. Baseline and 2.5 years uColl2-1NO<inf>2</inf> concentrations were assessed with enzyme-linked immunosorbent assay (ELISA). Primary outcome measure was incidence of knee OA in one or both knees, defined as incidence of either Kellgren & Lawrence grade ≥2, joint space narrowing of ≥1.0mm or knee OA according to the combined clinical and radiographic ACR-criteria. We used binary logistic regression for the association analyses.  \ud
__Results:__ 254 women were available for analyses. At 2.5 years follow-up, incident knee OA was present in 72 of 254 women (28.3%). An inversed association was found between baseline uColl2-1NO<inf>2</inf> and incident knee OA at 2.5 years (OR 0.74, 95% CI 0.55-0.99). The concentration at 2.5 years and the change in concentration over 2.5 years did not show significant associations with the outcome. Conclusions: In overweight and obese middle-aged women, not higher but lower baseline uColl2-1NO<inf>2</inf> concentration was significantly associated with an increased risk for incident knee OA. This interesting but counterintuitive outcome makes further validation of this biomarker warranted
Offering induction of labor for 22-week premature rupture of membranes: a survey of obstetricians

Objective: To describe obstetricians’ induction counseling practices for 22-week preterm premature rupture of membranes (PPROM) and identify provider characteristics associated with offering induction.
Methods: Surveyed 295 obstetricians on their likelihood (0–10) of offering induction for periviable PPROM across 10 vignettes. Twenty-two-week vignettes were analyzed, stratified by parental resuscitation preference. Bivariate analyses identified physician characteristics associated with reported likelihood ratings.
Results: Obstetricians (N=205) were not likely to offer induction. Median ratings by preference were as follows: resuscitation 1.0, uncertain 1.0 and comfort care 3.0. Only 41% of obstetricians were likely to offer induction to patients desiring comfort care. In addition, several provider-level factors, including practice region, parenting status and years in practice, were significantly associated with offering induction.
Conclusions: Obstetricians do not readily offer induction when counseling patients with 22-week ruptured membranes, even when patients prefer palliation. This may place women at risk for infectious complications without accruing a neonatal benefit from prolonged latency.This publication was made possible in part by Grant Number KL2 TR000163 (A.

Decimal Periods and their Tables : A German Research Topic (1765-1801)

International audienceAt the beginning of the 18th century, several mathematicians noted regularities in the decimal expansions of common fractions. Rules of thumb were set up, but it was only from 1760 onwards that the first attempts to try to establish a coherent theory of periodic decimal fractions appeared. J.H. Lambert was the first to devote two essays to the topic, but his colleagues at the Berlin Academy, J. III Bernoulli and J.L. Lagrange, also spent time on the problem. Apart from the theoretical side of the question, the applications (factoring, irrationality proofs and computational advantages) as well as the tabulation of decimal periods aroused considerable interest, especially among Lambert's correspondents, C.F. Hindenburg and I. Wolfram. Finally in 1797-1801 the young C.F. Gauss, informed of these developments, based the whole theory on firm number-theoretic foundations, thereby solving most of the open problems left by the mathematicians before him
Continuous crystal and Duistermaat-Heckman measure for Coxeter groups

International audienceWe introduce a notion of continuous crystal analogous, for general Coxeter groups, to the combinatorial crystals introduced by Kashiwara in representation theory of Lie algebras. We use a generalization of the Littelmann path model to show the existence of the crystals, and study an associated Duistermaat-Heckman measure, which we interpret in terms of Brownian motion. We also show that the Littelmann path operators can be derived from simple considerations on Sturm-Liouville equations
Enhanced Graph Rewriting Systems for Complex Software Domains (SoSyM Abstract)

International audienceMethodologies for correct by construction reconfigu-rations can efficiently solve consistency issues in dynamic software architecture. Graph-based models are appropriate for designing such architectures and methods. At the same time, they may be unfit to characterize a system from a non functional perspective. This stems from efficiency and applicability limitations in handling time-varying characteristics and their related dependencies. In order to lift these restrictions, an extension to graph rewriting systems is proposed herein. The suitability of this approach, as well as the restraints of currently available ones, are illustrated, analysed and experimentally evaluated with reference to a concrete example. This investigation demonstrates that the conceived solution can: (i) express any kind of algebraic dependencies between evolving requirements and properties; (ii) significantly ameliorate the efficiency and scalability of system modifications with respect to classic methodologies; (iii) provide an efficient access to attribute values; (iv) be fruitfully exploited in software management systems; (v) guarantee theoretical properties of a grammar, like its termination. This is an extended abstract for the Models 2015 Conference of the journal paper of the same name [1]. I. MOTIVATION Dynamic software architectures enable adaptation in evolving distributed systems. A crucial undesirable implication of such adaptations is a potential loss of correctness, the system withdrawing from its scope of consistency. Besides correctness, the system has evolving non-functional requirements, which are tightly linked to its appropriateness or efficiency. The satisfaction of these objectives depends on the properties of the system, its components, and their relations. On one hand, graph-based models are appropriate for the design of adaptation rules that necessarily preserve the system's consistency. On the other, currently available graph based methods exhibit limitations with regard to the description of system properties, in particular regarding their evolution and inter-dependencies
The capacitance and electromechanical coupling of lipid membranes close
  to transitions. The effect of electrostriction

Biomembranes are thin capacitors with the unique feature of displaying phase
transitions in a physiologically relevant regime. We investigate the voltage
and lateral pressure dependence of their capacitance close to their chain
melting transition. Since the gel and the fluid membrane have different area
and thickness, the capacitance of the two membrane phases is different. In the
presence of external fields, charges exert forces that can influence the state
of the membrane, thereby influencing the transition temperature. This
phenomenon is called electrostriction. We show that this effect allows us to
introduce a capacitive susceptibility that assumes a maximum in the melting
transition with an associated excess charge. As a consequence, there exist
voltage regimes where a small change in voltage can lead to a large uptake of
charge and a large capacitive current. Furthermore, we consider
electromechanical behavior such as pressure-induced changes in capacitance, and
the application of such concepts in biology.Comment: 5 figure
The surface signature of the tidal dissipationof the core in a two-layer planet

International audienceContext. Tidal dissipation, which is directly linked to internal structure, is one of the key physical mechanisms that drive the evolution of systems and govern their architecture. A robust evaluation of its amplitude is thus needed to predict the evolution time for spins and orbits and their final states. Aims. The purpose of this paper is to refine a recent model of the anelastic tidal dissipation in the central dense region of giant planets, which are commonly assumed to retain a large amount of heavy elements, which constitute an important source of dissipation. Methods. The previous paper evaluated the impact of the static fluid envelope on the tidal deformation of the core and on the associated anelastic tidal dissipation through the tidal quality factor Q c. We examine here its impact on the corresponding effective anelastic tidal dissipation through the effective tidal quality factor Q p. Results. We show that the strength of this mechanism mainly depends on mass concentration. In the case of Jupiter-and Saturn-like planets, it can increase their effective tidal dissipation by, around, factors 2.4 and 2, respectively. In particular, the range of the rheologies compatible with the observations is enlarged compared to the results issued from previous formulations. Conclusions. We derive here an improved expression of the tidal effective factor Q p in terms of the tidal dissipation factor of the core Q c , without assuming the commonly used assumptions. When applied to giant planets, the formulation obtained here allows a better match between the anelastic core's tidal dissipation of a two-layer model and the observations.

ALMA observations of cool dust in a low-metallicity starburst, SBS 0335−052

International audienceWe present Atacama Large Millimeter/submillimeter Array (ALMA) Cycle 0 Band 7          observations of an extremely metal-poor dwarf starburst galaxy in the Local Universe,          SBS 0335−052 (12 + log (O/H) ~ 7.2). With these observations, dust is detected at            870 μm (ALMA Band 7), but 87% of the flux in this band is due to          free-free emission from the starburst. We have compiled a spectral energy distribution          (SED) of SBS 0335−052 that spans almost 6 orders of magnitude in wavelength and fit it          with a spherical dust shell heated by a single-age stellar population; the best-fit model          gives a dust mass of (3.8    ±    0.6) × 104 M⊙. We          have also constructed a SED including Herschel archival data for I Zw 18,          another low-metallicity dwarf starburst (12 + log (O/H) ~ 7.17), and fit it with a similar          model to obtain a dust mass of            (3.4    ±    1.0) × 102 M⊙. It appears that for          such low-metallicity dwarf galaxies, the ratio of their stellar mass to their dust mass is          within the range of values found for spirals and other star-forming galaxies. However,          compared with their atomic gas mass, the dust mass of SBS 0335−052 far exceeds the          prediction of a linear trend of dust-to-gas mass ratio with metallicity, while I Zw 18          falls far below. We use gas scaling relations to assess a putative missing gas component          in both galaxies and find that the missing, possibly molecular, gas in SBS 0335−052 is a          factor of 6 times higher than the value inferred from the observed Hi column          density; in I Zw 18 the missing component is much smaller. Finally, we constrain the            H2 surface density conversion factor αCO with our          upper limit for CO J = 3−2 line in SBS 0335−052, and find that this is          consistent with a linear or even super-linear trend of increasing            αCO with decreasing metallicity. Ultimately, despite their          similarly low metallicity, the differences in gas and dust column densities in          SBS 0335−052 and I Zw 18 suggest that metal abundance does not uniquely define          star-formation processes. At some level, self-shielding and the survival of molecules may          depend just as much on gas and dust column density as on metallicity. The effects of low          metallicity may at least be partially compensated for by large column densities in the          interstellar medium
