The contribution of fluid geochemistry to define the structural pattern of the 2009 L’Aquila seismic source

Field investigations performed in the epicentral area within the days following the April 6, 2009
L’Aquila earthquake (Mw 6.3) allowed several researchers to detect evidence of coseismic ground
rupturing. This has been found along the Paganica Fault and next to minor synthetic and antithetic
structures. Although a lot of geo-structural and geophysical investigations have been recently used
to characterize these structures, the role of the different fault segments – i.e. as primary or
secondary faults – and their geometrical characteristics are still a matter of debate. In light of this,
we have here integrated data derived from fluid geochemistry analyses carried out soon after the
main-shock with field structural investigations. In particular, we compared structural data with CO2
and CH4 flux measurements, as well as with radon and other geogas soil concentration
measurements (see details in Voltattorni et al., this issue). Our aim was to better define the
structural features and complexities of the activated Paganica Fault. Here, we show that, in the near
rupture zone, “geochemical signatures” could be a powerful method to detect earthquake activated
fault segments, even if they show subtle or absent geological-geomorphological evidence and are
still partially “blind”. In detail, a clear degassing zone was identified just along the San Gregorio
coseismic fracture zone – i.e., the surface deformation related to the "blind" San Gregorio normal
fault. Indeed, CO2 and CH4 flux maximum anomalies were aligned along the Northern sector of the
San Gregorio fault, in the Bazzano industrial area. This area also corresponds to the depocenter of
the maximum coseismic deformation highlighted by DInSAR analysis (ATZORI ET AL., 2009). Here,
maximum radon concentration values in soil gases were also found. As a whole, these results
corroborates the hypothesis of BONCIO ET AL. (2010) who suggested that the San Gregorio fault
probably represents a synthetic splay of the Paganica Fault, being thus connected with the main
seismogenic fault at depth.Moreover, another maximum in CO2 flux anomaly has been measured along the southernmost tip of
the earthquake rupture zone, close to the San Gregorio village. Minor or absent soil gas and flux
anomalies were instead located along antithetic structures as the Bazzano and Fossa faults, while
some anomalies in CO2 flux or radon concentration in groundwater have been found within transfer
zones, such as the step-over zone between the central segment of the Paganica fault and the San
Gregorio fault and in the zone which separates the Paganica fault from the i) Middle Aterno Valley-
Subequana Valley and ii) Barisciano-S. Pio delle Camere-Navelli fault systems.
Our results corroborate the power of fluid geochemistry in investigating the structural features of
active tectonic structures, being particularly helpful in discerning blind faults. More specifically,
our data suggest that the youngest fault splays, as in the case of the San Gregorio fault, may
represent preferential sites for degassing
Cell-cycle regulation of NOTCH signaling during C. elegans vulval development

C. elegans vulval development is one of the best‐characterized systems to study cell fate specification during organogenesis. The detailed knowledge of the signaling pathways determining vulval precursor cell (VPC) fates permitted us to create a computational model based on the antagonistic interactions between the epidermal growth factor receptor (EGFR)/RAS/MAPK and the NOTCH pathways that specify the primary and secondary fates, respectively. A key notion of our model is called bounded asynchrony, which predicts that a limited degree of asynchrony in the progression of the VPCs is necessary to break their equivalence. While searching for a molecular mechanism underlying bounded asynchrony, we discovered that the termination of NOTCH signaling is tightly linked to cell‐cycle progression. When single VPCs were arrested in the G1 phase, intracellular NOTCH failed to be degraded, resulting in a mixed primary/secondary cell fate. Moreover, the G1 cyclins CYD‐1 and CYE‐1 stabilize NOTCH, while the G2 cyclin CYB‐3 promotes NOTCH degradation. Our findings reveal a synchronization mechanism that coordinates NOTCH signaling with cell‐cycle progression and thus permits the formation of a stable cell fate pattern.Peer-reviewedPublisher Versio
Deformation structures associated with the Trachyte Mesa intrusion, Henry Mountains, Utah : Implications for sill and laccolith emplacement mechanisms.

Deformation structures in the wall rocks of igneous intrusions emplaced at shallow crustal depths preserve an important record of how space was created for magma in the host rocks. Trachyte Mesa, a small Oligocene age intrusion in the Henry Mountains, Utah, is composed of a series of stacked tabular, sheet-like intrusions emplaced at 3–3.5 km depth into sandstone-dominated sedimentary sequences of late Palaeozoic–Mesozoic age. New structural analysis of the spatial distribution, geometry, kinematics and relative timings of deformation structures in the host rocks of the intrusion has enabled the recognition of distinct pre-, syn-, and late-stage-emplacement deformation phases. Our observations suggest a two-stage growth mechanism for individual sheets where radial growth of a thin sheet was followed by vertical inflation. Dip-slip faults formed during vertical inflation; they are restricted to the tips of individual sheets due to strain localisation, with magma preferentially exploiting these faults, initiating sill (sheet) climbing. The order in which sheets are stacked impacts on the intrusion geometry and associated deformation of wall rocks. Our results offer new insights into the incremental intrusion geometries of shallow-level magmatic bodies and the potential impact of their emplacement on surrounding host rocks
Str\"omgren uvby photometry of the peculiar globular cluster NGC 2419

NGC 2419 is a peculiar Galactic globular cluster in terms of size/luminosity,
and chemical abundance anomalies. Here, we present Str\"omgren $uvby$
photometry of the cluster. Using the gravity- and metallicity-sensitive $c_1$
and $m_1$ indices, we identify a sample of likely cluster members extending
well beyond the formal tidal radius with an estimated contamination by
non-members of only 1%. We derive photometric [Fe/H] of red giants, and
depending on which literature metallicity relation we use, find reasonable to
excellent agreement with spectroscopic [Fe/H]. We demonstrate explicitly that
the photometric errors are not Gaussian, and using a realistic model for the
photometric uncertainties, find a formal internal [Fe/H] spread of
$\sigma=0.11^{+0.02}_{-0.01}$ dex. This is an upper limit to the cluster's true
[Fe/H] spread and may partially/entirely reflect the limited precision of the
photometric metallicity estimation and systematic effects. The lack of
correlation between spectroscopic and photometric [Fe/H] of individual stars is
further evidence against a [Fe/H] spread on the 0.1 dex level. Finally, the
CN-sensitive $\delta_4$ anti-correlates strongly with Mg abundance, indicating
that the 2nd generation stars are N-enriched. Absence of similar correlations
in some other CN-sensitive indices supports the second generation being
He-rich, which in these indices approximately compensates the shift due to CN.
Compared to a single continuous distribution with finite dispersion, the
observed $\delta_4$ distribution is slightly better fit by two discrete
populations, with the N-enhanced stars accounting for 53$\pm$5%. NGC 2419
appears to be very similar to other metal-poor Galactic globular clusters with
a similarly N-enhanced second generation and little or no variation in [Fe/H],
which sets it apart from other suspected accreted nuclei such as {\omega}Cen.

Non-Markovian Quantum Feedback Networks I: Quantum Transmission Lines,
  Lossless Bounded Real Property and Limit Markovian Channels

The purpose of this paper is to set out the problems of modeling quantum
communication and signal processing where the communication between systems via
a non-Markovian channel. This is a general feature of quantum transmission
lines. Our ultimate objective is to extend the networks rules that have been
developed for Markovian models. To this end we recall the Hamiltonian
description of such non-Markov models of transmission lines and their
quantization. These have occurred in the context of non-quilibrium
thermodynamics, but our interest is in the transmission lines as carriers of
information rather than heat baths. We show that there is an analytic
scattering matrix associated with these models and that stability may be
formulated in terms of the lossless bounded real property. Noting that the
input and output fields do not separately satisfy a non-self- demolition
principle, we discuss the rigorous limit in which such models appear Markov and
so amenable to standard approaches of quantum filtering and controlComment: 13 pages, 4 figure
Narcolepsy patients have antibodies that stain distinct cell populations in rat brain and influence sleep patterns

Narcolepsy is a chronic sleep disorder, likely with an autoimmune component. During 2009 and 2010, a link between A(H1N1)pdm09 Pandemrix vaccination and onset of narcolepsy was suggested in Scandinavia. In this study, we searched for autoantibodies related to narcolepsy using a neuroanatomical array: rat brain sections were processed for immunohistochemistry/double labeling using patient sera/cerebrospinal fluid as primary antibodies. Sera from 89 narcoleptic patients, 52 patients with other sleep-related disorders (OSRDs), and 137 healthy controls were examined. Three distinct patterns of immunoreactivity were of particular interest: pattern A, hypothalamic melanin-concentrating hormone and proopiomelanocortin but not hypocretin/orexin neurons; pattern B, GABAergic cortical interneurons; and pattern C, mainly globus pallidus neurons. Altogether, 24 of 89 (27%) narcoleptics exhibited pattern A or B or C. None of the patterns were exclusive for narcolepsy but were also detected in the OSRD group at significantly lower numbers. Also, some healthy controls exhibited these patterns. The antigen of pattern A autoantibodies was identified as the common C-terminal epitope of neuropeptide glutamic acid-isoleucine/α-melanocyte-stimulating hormone (NEI/αMSH) peptides. Passive transfer experiments on rat showed significant effects of pattern A human IgGs on rapid eye movement and slow-wave sleep time parameters in the inactive phase and EEG θ-power in the active phase. We suggest that NEI/αMSH autoantibodies may interfere with the fine regulation of sleep, contributing to the complex pathogenesis of narcolepsy and OSRDs. Also, patterns B and C are potentially interesting, because recent data suggest a relevance of those brain regions/neuron populations in the regulation of sleep/arousal
Submarine landform assemblages and sedimentary processes related to glacier surging in Kongsfjorden, Svalbard

inner Kongsfjorden, Svalbard, reveal characteristic landform
assemblages formed during and after surges of tidewater
glaciers, and provide new insights into the dynamics
of surging glaciers. Glacier front oscillations and overriding
related to surge activity lead to the formation of
overridden moraines, glacial lineations of two types, terminal
moraines, associated debris lobes and De Geer
moraines. In contrast to submarine landform assemblages
from other Svalbard fjords, the occurrence of two kinds of
glacial lineations and the presence of De Geer moraines
suggest variability in the landforms produced by surge-type
tidewater glaciers. All the landforms in inner Kongsfjorden
were deposited during the last c. 150 years. Lithological
and acoustic data from the innermost fjord reveal that
suspension settling from meltwater plumes as well as ice
rafting are dominant sedimentary processes in the fjord,
leading to the deposition of stratified glacimarine muds
with variable numbers of clasts. Reworking of sediments
by glacier surging results in the deposition of sediment
lobes containing massive glacimarine muds. Two sediment cores reveal minimum sediment accumulation rates related
to the Kongsvegen surge from 1948; these were 30 cm a-1
approximately 2.5 km beyond the glacier front shortly after
surge termination, and rapidly dropped to an average rate
of 1.8 cm a-1 in  1950, during glacier retreat
Search for events with large missing transverse momentum, jets, and at least two tau leptons in 7 TeV proton-proton collision data with the ATLAS detector ATLAS Collaboration

A search for events with large missing transverse momentum, jets, and at least two tau leptons has been performed using 2 fb(-1) of proton-proton collision data at root s = 7 TeV recorded with the ATLAS detector at the Large Hadron Collider. No excess above the Standard Model background expectation is observed and a 95% CL upper limit on the visible cross section for new phenomena is set, where the visible cross section is defined by the product of cross section, branching fraction, detector acceptance and event selection efficiency. A 95% CL lower limit of 32 TeV is set on the gauge-mediated supersymmetry breaking (GMSB) scale Lambda independent of tan beta. These limits provide the most stringent tests to date in a large part of the considered parameter space. Published by Elsevier B.V
Fiducial and differential cross sections of higgs boson production measured in the four-lepton decay channel in pp collisions at root s=8 TeV with the ATLAS detector

Measurements of fiducial and differential cross sections of Higgs boson production in the H -> ZZ* -> 4l decay channel are presented. The cross sections are determined within a fiducial phase space and corrected for detection efficiency and resolution effects. They are based on 20.3 fb(-1) of pp collision data, produced at root s= 8 TeV centre-of-mass energy at the LHC and recorded by the ATLAS detector. The differential measurements are performed in bins of transverse momentum and rapidity of the four-lepton system, the invariant mass of the subleading lepton pair and the decay angle of the leading lepton pair with respect to the beam line in the four-lepton rest frame, as well as the number of jets and the transverse momentum of the leading jet. The measured cross sections are compared to selected theoretical calculations of the Standard Model expectations. No significant deviation from any of the tested predictions is found
Search for diphoton events with large missing transverse momentum in 1 fb-1 of 7 TeV proton-proton collision data with the ATLAS detector

A search for diphoton events with large missing transverse momentum has been performed using 1.07 fb-1 of proton-proton collision data at s=7 TeV recorded with the ATLAS detector. No excess of events was observed above the Standard Model prediction and 95% Confidence Level (CL) upper limits are set on the production cross section for new physics. The limits depend on each model parameter space and vary as follows: Λ<(22-129) fb in the context of a generalised model of gauge-mediated supersymmetry breaking (GGM) with a bino-like lightest neutralino, σ<(27-91) fb in the context of a minimal model of gauge-mediated supersymmetry breaking (SPS8), and σ<(15-27) fb in the context of a specific model with one universal extra dimension (UED). A 95% CL lower limit of 805 GeV, for bino masses above 50 GeV, is set on the GGM gluino mass. Lower limits of 145 TeV and 1.23 TeV are set on the SPS8 breaking scale Λ and on the UED compactification scale 1/R, respectively. These limits provide the most stringent tests of these models to date
Brownian regime of finite- N corrections to particle motion in the XY Hamiltonian mean field model

International audienceWe study the dynamics of the N-particle system evolving in the XY hamiltonian mean field (HMF) model for a repulsive potential, when no phase transition occurs. Starting from a homogeneous distribution, particles evolve in a mean field created by the interaction with all others. This interaction does not change the homogeneous state of the system, and particle motion is approximately ballistic with small corrections. For initial particle data approaching a waterbag, it is explicitly proved that corrections to the ballistic velocities are in the form of independent brownian noises over a time scale diverging not slower than N^(2/5) as N → ∞, which proves the propagation of molecular chaos. Molecular dynamics simulations of the XY-HMF model confirm our analytical findings
Kinematics of fluid particles on the sea surface. Part 1. Hamiltonian theory

International audienceWe derive the John-Sclavounos equations describing the motion of a fluid particle on the sea surface from first principles using Lagrangian and Hamiltonian formalisms applied to the motion of a frictionless particle constrained on an unsteady surface. The main result is that vorticity generated on a stress-free surface vanishes at a wave crest when the horizontal particle velocity equals the crest propagation speed, which is the kinematic criterion for wave breaking. If this holds for the largest crest, then the symplectic two-form associated with the Hamiltonian dynamics reduces instantaneously to that associated with the motion of a particle in free flight, as if the surface did not exist. Further, exploiting the conservation of the Hamiltonian function for steady surfaces and traveling waves we show that particle velocities remain bounded at all times, ruling out the possibility of the finite-time blowup of solutions
clOpenCL : supporting distributed heterogeneous computing in HPC clusters

Clusters that combine heterogeneous compute device architectures, coupled with novel programming models, have created a true alternative to traditional (homogeneous) cluster computing, allowing to leverage the performance of parallel applications. In this paper we introduce
clOpenCL, a platform that supports the simple deployment and efficient running of OpenCL-based parallel applications that may span several cluster nodes, expanding the original single-node OpenCL model.
clOpenCL is deployed through user level services, thus allowing OpenCL applications from different users to share the same cluster nodes and their compute devices. Data exchanges between distributed clOpenCL components rely on Open-MX, a high-performance communication library. We also present extensive experimental data and key conditions that must be addressed when exploiting clOpenCL with real applications.Fundação para a Ciência e Tecnologi
Affective focus increases the concordance between implicit and explicit attitudes

Two attitude dichotomies - implicit versus explicit and affect versus cognition - are presumed to be related. Following a manipulation of attitudinal focus (affective or cognitive), participants completed two implicit measures (Implicit Association Test and the Sorting Paired Features task) and three explicit attitude measures toward cats/dogs (Study 1) and gay/straight people (Study 2). Based on confirmatory factor analysis, both studies showed that explicit attitudes were more related to implicit attitudes in an affective focus than in a cognitive focus. We suggest that, although explicit evaluations can be meaningfully parsed into affective and cognitive components, implicit evaluations are more related to affective than cognitive components of attitudes
Relative Entanglement Entropies in 1+1-dimensional conformal field
  theories

We study the relative entanglement entropies of one interval between excited
states of a 1+1 dimensional conformal field theory (CFT). To compute the
relative entropy $S(\rho_1 \| \rho_0)$ between two given reduced density
matrices $\rho_1$ and $\rho_0$ of a quantum field theory, we employ the replica
trick which relies on the path integral representation of ${\rm Tr} ( \rho_1
\rho_0^{n-1} )$ and define a set of R\'enyi relative entropies $S_n(\rho_1 \|
\rho_0)$. We compute these quantities for integer values of the parameter $n$
and derive via the replica limit, the relative entropy between excited states
generated by primary fields of a free massless bosonic field. In particular, we
provide the relative entanglement entropy of the state described by the primary
operator $i \partial\phi$, both with respect to the ground state and to the
state generated by chiral vertex operators. These predictions are tested
against exact numerical calculations in the XX spin-chain finding perfect
agreement.Comment: 24 pages, 5 figure
Measurements of top-quark pair to $Z$-boson cross-section ratios at
  $\sqrt s = 13, 8, 7$TeV with the ATLAS detector

Ratios of top-quark pair to $Z$-boson cross sections measured from
proton--proton collisions at the LHC centre-of-mass energies of $\sqrt
s=13$TeV, 8TeV, and 7TeV are presented by the ATLAS Collaboration. Single
ratios, at a given $\sqrt s$ for the two processes and at different $\sqrt s$
for each process, as well as double ratios of the two processes at different
$\sqrt s$, are evaluated. The ratios are constructed using previously published
ATLAS measurements of the $t\overline{t}$ and $Z$-boson production cross
sections, corrected to a common phase space where required, and a new analysis
of $Z \rightarrow \ell^+ \ell^-$ where $\ell=e,\mu$ at $\sqrt s=13$TeV
performed with data collected in 2015 with an integrated luminosity of
$3.2$fb$^{-1}$. Correlations of systematic uncertainties are taken into account
when evaluating the uncertainties in the ratios. The correlation model is also
used to evaluate the combined cross section of the $Z\rightarrow e^+e^-$ and
the $Z\rightarrow \mu^+ \mu^-$ channels for each $\sqrt s$ value. The results
are compared to calculations performed at next-to-next-to-leading-order
accuracy using recent sets of parton distribution functions. The data
demonstrate significant power to constrain the gluon distribution function for
the Bjorken-$x$ values near 0.1 and the light-quark sea for $x<0.02$.Comment: 55 pages in total, author list starting page 34, 9 figures, 18
