Infants born late/moderately preterm are at increased risk for a positive autism screen at 2 years of age.

Objectives To assess the prevalence of positive screens using the Modified Checklist for Autism in Toddlers\ud
(M-CHAT) questionnaire and follow-up interview in late and moderately preterm (LMPT; 32-36 weeks) infants\ud
and term-born controls.\ud
Study design Population-based prospective cohort study of 1130 LMPT and 1255 term-born infants. Parents\ud
completed the M-CHAT questionnaire at 2-years corrected age. Parents of infants with positive questionnaire\ud
screens were followed up with a telephone interview to clarify failed items. The M-CHAT questionnaire was rescored,\ud
and infants were classified as true or false positives. Neurosensory, cognitive, and behavioral outcomes\ud
were assessed using parent report.\ud
Results Parents of 634 (57%) LMPT and 761 (62%) term-born infants completed the M-CHAT questionnaire.\ud
LMPT infants had significantly higher risk of a positive questionnaire screen compared with controls (14.5% vs\ud
9.2%; relative risk [RR] 1.58; 95% CI 1.18, 2.11). After follow-up, significantly more LMPT infants than controls\ud
had a true positive screen (2.4% vs 0.5%; RR 4.52; 1.51, 13.56). This remained significant after excluding infants\ud
with neurosensory impairments (2.0% vs 0.5%; RR 3.67; 1.19, 11.3).\ud
Conclusions LMPT infants are at significantly increased risk for positive autistic screen. An M-CHAT follow-up\ud
interview is essential as screening for autism spectrum disorders is especially confounded in preterm populations.\ud

The design of reliable circuits using logic redundancy.

With the increasing demand for more durable products, the necessity of designing more resilient products is evident. When it comes to electronic systems, many strategies have been applied to enhance the durability and performance of the operating circuits. For a long time, the main focus was to develop increasingly reliable components, however, yield enhancement techniques may not be sufficient for future technologies. As a solution to this, redundancy strategies are being introduced in order to regain reliability of circuits even if the individual components are not as reliable as desired. The use of logic redundancy and series or parallel association of transistors is proposed as a strategy in the design of fault tolerant logic gates (that are the basic elements of many complex computing structures), such as NAND and NOR. Fault injection simulations show that the reliability of these gates in the presence of random stuck-at faults may be increased by our design approach and that the strategy is extensible to more elaborate circuits
A dynamin-actin interaction is required for vesicle scission during endocytosis in yeast.

Actin is critical for endocytosis in yeast cells, and also in mammalian cells under tension. However, questions remain as to how force generated through actin polymerization is transmitted to the plasma membrane to drive invagination and scission. Here, we reveal that the yeast dynamin Vps1 binds and bundles filamentous actin. Mutational analysis of Vps1 in a helix of the stalk domain identifies a mutant RR457-458EE that binds actin more weakly. In vivo analysis of Vps1 function demonstrates that the mutation disrupts endocytosis but not other functions of Vps1 such as vacuolar trafficking or peroxisome fission. The mutant Vps1 is stably expressed in cells and co-localizes with the endocytic reporters Abp1 and the amphiphysin Rvs167. Detailed analysis of individual endocytic patch behavior indicates that the mutation causes aberrant movements in later stages of endocytosis, consistent with a scission defect. Ultrastructural analysis of yeast cells using electron microscopy reveals a significant increase in invagination depth, further supporting a role for the Vps1-actin interaction during scission. In vitro analysis of the mutant protein demonstrates that—like wild-type Vps1—it is able to form oligomeric rings, but, critically, it has lost its ability to bundle actin filaments into higher-order structures. A model is proposed in which actin filaments bind Vps1 during invagination, and this interaction is important to transduce the force of actin polymerization to the membrane to drive successful scission
Balancing competing policy demands :
                    the case of sustainable public sector food procurement

The article argues that clarifying the difference between green and sustainable public sector food procurement, with political continuity that supports and enables policymakers and practitioners to take an incremental approach to change, makes an important contribution to delivering more sustainable food systems and better public health nutrition. Five European case studies demonstrate the reality of devising and implementing innovative approaches to sustainable public sector food procurement and the effects of cultural and political framings. How legislation is enacted at the national level and interpreted at the local level is a key driver for sustainable procurement. Transition is dependent on political will and leadership and an infrastructure that can balance the economic, environmental and social drivers to effect change. The development of systems and indicators to measure change, reforms to EU directives on procurement, and the relationship between green growth strategies and sustainable diets are also discussed. The findings show the need to explore how consistent definitions for green public procurement and sustainable public procurement can be refined and standardized in order to support governments at all levels in reviewing and analysing their current food procurement strategies and practices to improve sustainabilit
The Gamma-Ray Emitting Radio-Loud Narrow-Line Seyfert 1 Galaxy PKS
  2004-447 II. The Radio View

Gamma-ray detected radio-loud narrow-line Seyfert 1 (g-NLS1) galaxies
constitute a small but interesting sample of the gamma-ray loud AGN. The
radio-loudest g-NLS1 known, PKS 2004-447, is located in the southern hemisphere
and is monitored in the radio regime by the multiwavelength monitoring program
TANAMI. We aim for the first detailed study of the radio morphology and
long-term radio spectral evolution of PKS 2004-447, which are essential to
understand the diversity of the radio properties of g-NLS1s. The TANAMI VLBI
monitoring program uses the Australian Long Baseline Array (LBA) and telescopes
in Antarctica, Chile, New Zealand, and South Africa to monitor the jets of
radio-loud active galaxies in the southern hemisphere. Lower resolution radio
flux density measurements at multiple radio frequencies over four years of
observations were obtained with the Australia Telescope Compact Array (ATCA).
The TANAMI VLBI image at 8.4 GHz shows an extended one-sided jet with a
dominant compact VLBI core. Its brightness temperature is consistent with
equipartition, but it is an order of magnitude below other g-NLS1s with the
sample value varying over two orders of magnitude. We find a compact morphology
with a projected large-scale size <11 kpc and a persistent steep radio spectrum
with moderate flux-density variability. PKS 2004-447 appears to be a unique
member of the g-NLS1 sample. It exhibits blazar-like features, such as a flat
featureless X-ray spectrum and a core dominated, one-sided parsec-scale jet
with indications for relativistic beaming. However, the data also reveal
properties atypical for blazars, such as a radio spectrum and large-scale size
consistent with Compact-Steep-Spectrum (CSS) objects, which are usually
associated with young radio sources. These characteristics are unique among all
g-NLS1s and extremely rare among gamma-ray loud AGN.Comment: 11 pages, 4 figures, accepted by Astronomy & Astrophysic
A dispersive wave pattern on Jupiter's fastest retrograde jet at
  $20^\circ$S

A compact wave pattern has been identified on Jupiter's fastest retrograding
jet at 20S (the SEBs) on the southern edge of the South Equatorial Belt. The
wave has been identified in both reflected sunlight from amateur observations
between 2010 and 2015, thermal infrared imaging from the Very Large Telescope
and near infrared imaging from the Infrared Telescope Facility. The wave
pattern is present when the SEB is relatively quiescent and lacking large-scale
disturbances, and is particularly notable when the belt has undergone a fade
(whitening). It is generally not present when the SEB exhibits its usual
large-scale convective activity ('rifts'). Tracking of the wave pattern and
associated white ovals on its southern edge over several epochs have permitted
a measure of the dispersion relationship, showing a strong correlation between
the phase speed (-43.2 to -21.2 m/s) and the longitudinal wavelength, which
varied from 4.4-10.0 deg. longitude over the course of the observations.
Infrared imaging sensing low pressures in the upper troposphere suggest that
the wave is confined to near the cloud tops. The wave is moving westward at a
phase speed slower (i.e., less negative) than the peak retrograde wind speed
(-62 m/s), and is therefore moving east with respect to the SEBs jet peak.
Unlike the retrograde NEBn jet near 17N, which is a location of strong vertical
wind shear that sometimes hosts Rossby wave activity, the SEBs jet remains
retrograde throughout the upper troposphere, suggesting the SEBs pattern cannot
be interpreted as a classical Rossby wave. Cassini-derived windspeeds and
temperatures reveal that the vorticity gradient is dominated by the baroclinic
term and becomes negative (changes sign) in a region near the cloud-top level
(400-700 mbar) associated with the SEBs, suggesting a baroclinic origin for
this meandering wave pattern. [Abr]Comment: 19 pages, 11 figures, article accepted for publication in Icaru
Measurement of the W boson helicity fractions in the decays of top quark
  pairs to lepton + jets final states produced in pp collisions at sqrt(s) = 8
  TeV

The W boson helicity fractions from top quark decays in t t-bar events are
measured using data from proton-proton collisions at a centre-of-mass energy of
8 TeV. The data were collected in 2012 with the CMS detector at the LHC,
corresponding to an integrated luminosity of 19.8 inverse femtobarns. Events
are reconstructed with either one muon or one electron, along with four jets in
the final state, with two of the jets being identified as originating from b
quarks. The measured helicity fractions from both channels are combined,
yielding F[0] = 0.681 +/- 0.012 (stat) +/- 0.023 (syst), F[L] = 0.323 +/- 0.008
(stat) +/- 0.014 (syst), and F[R] = -0.004 +/- 0.005 (stat) +/- 0.014 (syst)
for the longitudinal, left-, and right-handed components of the helicity,
respectively. These measurements of the W boson helicity fractions are the most
accurate to date and they agree with the predictions from the standard model.Comment: Replaced with published version. Added the journal reference. All the

Synthesis of C-rich dust in CO nova ourbursts

Context. Classical novae are thermonuclear explosions that take place in the
envelopes of accreting white dwarfs in stellar binary systems. The material
transferred onto the white dwarf piles up under degenerate conditions, driving
a thermonuclear runaway. In those outbursts, about 10-7 - 10-3 Msun, enriched
in CNO and, sometimes, other intermediate-mass elements (e.g., Ne, Na, Mg, or
Al, for ONe novae) are ejected into the interstellar medium. The large
concentrations of metals spectroscopically inferred in the nova ejecta reveal
that the (solar-like) material transferred from the secondary mixes with the
outermost layers of the underlying white dwarf.
  Aims. Most theoretical models of nova outbursts reported to date yield, on
average, outflows characterized by O > C, from which only oxidized condensates
(e.g, O-rich grains) would be expected, in principle.
  Methods. To specifically address whether CO novae can actually produce C-rich
dust, six different hydrodynamic nova models have been evolved, from accretion
to the expansion and ejection stages, with different choices for the
composition of the substrate with which the solar-like accreted material mixes.
Updated chemical profiles inside the H-exhausted core have been used, based on
stellar evolution calculations for a progenitor of 8 Msun through H and
He-burning phases.
  Results. We show that these profiles lead to C-rich ejecta after the nova
outburst. This extends the possible contribution of novae to the inventory of
presolar grains identified in meteorites, particularly in a number of
carbonaceous phases (i.e., nanodiamonds, silicon carbides and graphites).Comment: 5 pages, accepted for publication in Astronomy & Astrophysic
Radio continuum and X-ray emission from the most extreme FIR-excess
  galaxy NGC 1377: An extremely obscured AGN revealed

Galaxies which strongly deviate from the radio-far IR correlation are of
great importance for studies of galaxy evolution as they may be tracing early,
short-lived stages of starbursts and active galactic nuclei (AGNs). The most
extreme FIR-excess galaxy NGC1377 has long been interpreted as a young dusty
starburst, but millimeter observations of CO lines revealed a powerful
collimated molecular outflow which cannot be explained by star formation alone.
We present new radio observations at 1.5 and 10 GHz obtained with the Jansky
Very Large Array (JVLA) and Chandra X-ray observations towards NGC1377. The
observations are compared to synthetic starburst models to constrain the
properties of the central energy source. We obtained the first detection of the
cm radio continuum and X-ray emission in NGC1377. We find that the radio
emission is distributed in two components, one on the nucleus and another
offset by 4$"$.5 to the South-West. We confirm the extreme FIR-excess of the
galaxy, with a $q_\mathrm{FIR}\simeq$4.2, which deviates by more than
7-$\sigma$ from the radio-FIR correlation. Soft X-ray emission is detected on
the off-nucleus component. From the radio emission we estimate for a young
($<10$ Myr) starburst a star formation rate SFR$<$0.1 M$_\odot$ yr$^{-1}$. Such
a SFR is not sufficient to power the observed IR luminosity and to drive the CO
outflow. We find that a young starburst cannot reproduce all the observed
properties of the nucleus of NGC1377. We suggest that the galaxy may be
harboring a radio-quiet, obscured AGN of 10$^6$M$_\odot$, accreting at
near-Eddington rates. We speculate that the off-nucleus component may be
tracing an hot-spot in the AGN jet.Comment: 14 pages, accepted for publication on Astronomy and Astrophysics on

Response of seagrass indicators to shifts in environmental stressors: Aglobal review and management synthesis

14 páginas, 6 figuras, 6 tablasAlthough seagrass-based indicators are widely used to assess coastal ecosystem status, there is littleuniversality in their application. Matching the plethora of available indicators to specific managementobjectives requires a detailed knowledge of their species-specific sensitivities and their response timeto environmental stressors. We conducted an extensive survey of experimental studies to determine thesensitivity and response time of seagrass indicators to ecosystem degradation and recovery. We iden-tified seagrass size and indicator type (i.e. level of biological organization of the measure) as the mainfactors affecting indicator sensitivity and response time to degradation and recovery. While structuraland demographic parameters (e.g. shoot density, biomass) show a high and unspecific sensitivity, bio-chemical/physiological indicators present more stressor-specific responses and are the most sensitivedetecting early phases of environmental improvement. Based on these results we present a simple deci-sion tree to assist ecosystem managers to match adequate and reliable indicators to specific managementgoals.This work was funded by the COST action ES0906, the Spanish Ministry of Science and Innovation (projects CTM2010-22273-C02-01 and -02) and CSIC- 201330E062.

Contrast estimator for completely or partially observed hypoelliptic diffusion

International audienceParametric estimation of two-dimensional hypoelliptic diffusions is considered when complete observations -both coordinates discretely observed- or partial observations -only one coordinate observed are available. Since the volatility matrix is degenerate, Euler contrast estimators cannot be used directly. For complete observations, we introduce an Euler contrast based on the second coordinate only. For partial observations, we define a contrast based on an integrated diffusion resulting from a transformation of the original one. A theoretical study proves that the estimators are consistent and asymptotically Gaussian. A numerical application to Langevin systems illustrates the nice properties of both complete and partial observations estimators
Measurement of the inclusive isolated prompt photon cross-section in pp collisions at root s=7 TeV using 35 pb(-1) of ATLAS data

A measurement of the differential cross-section for the inclusive production of isolated prompt photons in pp collisions at a center-of-mass energy root s = 7 TeV is presented. The measurement covers the pseudorapidity ranges vertical bar eta vertical bar < 1.37 and 1.52 <= vertical bar eta vertical bar < 2.37 in the transverse energy range 45 <= E-T < 400 GeV. The results are based on an integrated luminosity of 35 pb(-1), collected with the ATLAS detector at the LHC. The yields of the signal photons are measured using a data-driven technique, based on the observed distribution of the hadronic energy in a narrow cone around the photon candidate and the photon selection criteria. The results are compared with next-to-leading order perturbative QCD calculations and found to be in good agreement over four orders of magnitude in cross-section
Search for a heavy gauge boson decaying to a charged lepton and a neutrino in 1 fb(-1) of pp collisions at root s=7 TeV using the ATLAS detector ATLAS Collaboration

The ATLAS detector at the LHC is used to search for high-mass states, such as heavy charged gauge bosons (W '), decaying to a charged lepton (electron or muon) and a neutrino. Results are presented based on the analysis of pp collisions at a center-of-mass energy of 7 TeV corresponding to an integrated luminosity of 1.04 fb(-1). No excess above Standard Model expectations is observed. A W ' with Sequential Standard Model couplings is excluded at the 95% confidence level for masses up to 2.15 TeV
The Incidence of Debris Disks at 24 {\mu}m and 670 Myr

We use Spitzer Space Telescope 24 {\mu}m data to search for debris disks
among 122 AFGKM stars from the \sim 670 Myr clusters Hyades, Coma Ber, and
Praesepe, utilizing a number of advances in data reduction and determining the
intrinsic colors of main sequence stars. For our sample, the 1{\sigma}
dispersion about the main sequence V-K, K-[24] locus is approximately 3.1%. We
identify seven debris disks at 10% or more (\geq 3{\sigma} confidence level)
above the expected K-[24] for purely photospheric emission. The incidence of
excesses of 10% or greater in our sample at this age is 5.7 +3.1/-1.7%.
Combining with results from the literature, the rate is 7.8 +4.2/-2.1% for
early- type (B9 - F4) stars and 2.7 +3.3/-1.7% for solar-like (F5 - K9) stars.
Our primary sample has strict criteria for inclusion to allow comparison with
other work; when we relax these criteria, three additional debris disks are
detected. They are all around stars of solar-like type and hence reinforce our
conclusion that disks around such stars are still relatively common at 670 Myr
and are similar to the rate around early-type stars. The apparently small
difference in decay rates between early-type and solar-like stars is
inconsistent with the first order theoretical predictions that the later type
stellar disks would decay an order of magnitude more quickly than the earlier
type ones.Comment: 26 pages, 3 figures, accepted for publication in Ap
Ferromagnetic resonance and magnetic damping in C-doped Mn 5 Ge 3

International audience2 X-band ferromagnetic resonance (FMR) was used to investigate static and dynamic magnetic properties of Mn5Ge3 and Carbon-doped Mn5Ge3 (C0.1 and C0.2) thin films grown on Ge(111). The temperature dependence of magnetic anisotropy shows an increased perpendicular magneto-crystalline contribution at low temperature with an in-plane easy axis due to the large shape contribution. We find that our samples show as small as 40Oe FMR linewidth (corresponding Gilbert damping α=0.005), for the out-of-plane direction, certifying of their very good structural quality. The perpendicular linewidth shows a minimum around 200K for all samples, which seems not correlated to the C-doping. The magnetic relaxation parameters have been determined and indicate as main extrinsic contribution the two-magnon scattering. A transition from six-fold to twofold plus fourth-fold in-plane anisotropy is observed in the FMR linewidth of Mn5Ge3C0.2 around 200K
