Search for supersymmetry in events with large missing transverse momentum, jets, and at least one tau lepton in 20 fb(-1) of root s=8 TeV proton-proton collision data with the ATLAS detector

A search for supersymmetry (SUSY) in events with large missing transverse momentum, jets, at least one hadronically decaying tau lepton and zero or one additional light leptons (electron/muon), has been performed using 20.3 fb(-1) of proton-proton collision data at root s = 8 TeV recorded with the ATLAS detector at the Large Hadron Collider. No excess above the Standard Model background expectation is observed in the various signal regions and 95% confidence level upper limits on the visible cross section for new phenomena are set. The results of the analysis are interpreted in several SUSY scenarios, significantly extending previous limits obtained in the same final states. In the framework of minimal gauge-mediated SUSY breaking models, values of the SUSY breaking scale Lambda below 63 TeV are excluded, independently of tan beta. Exclusion limits are also derived for an mSUGRA/CMSSM model, in both the R-parity-conserving and R-parity-violating case. A further interpretation is presented in a framework of natural gauge mediation, in which the gluino is assumed to be the only light coloured sparticle and gluino masses below 1090 GeV are excluded
The Digital Coral: Infrastructuring Environmental Monitoring

Technologies for collaboration within the oil and gas industry, which are referred to as Integrated Operations, challenge traditional geographical, disciplinary, and organisational boundaries. Fuelled by the availability of sensor networks, faster data transfer technologies, shared data exchange formats, and collaborative work flows, Integrated Operations entail difficult transformations at the technological, social, and political levels. We describe and discuss the efforts of a Scandinavian oil and gas company to develop an information infrastructure for real-time subsea environmental monitoring. This accentuates the ongoing controversy among environmental concerns, fisheries, and the oil and gas industry. Theoretically leaning on infrastructuring and, methodologically, on the concept of infrastructural inversion, our analysis specifically targets the evolution of emergent infrastructures. We identify and discuss the increasing degree of entanglement of the infrastructuring process over time by empirically characterizing two concepts: (1) bootstrapping, which is particularly pronounced in the early stages of infrastructure evolution and involves exploring the local feasibility of subsea environmental monitoring methods and devices, and (2) enactment, which is increasingly present in the later stages of infrastructure evolution to weave environmental information into the agenda of heterogeneous oil and gas professionals.© Springer Science+Business.

Dissecting subsecond cadherin bound states reveals an efficient way for cells to achieve ultrafast probing of their environment.

International audienceCells continuously probe their environment with membrane receptors, achieving subsecond adaptation of their behaviour [Diez, G., Gerisch, G., Anderson, K., M?r-Taubenberger, A. and Bretschneider, T.

Here we show at the single molecule level that homotypic C-cadherin association involves transient intermediates lasting less than a few tens of milliseconds. Further, these intermediates transitionned towards more stable states with a kinetic rate displaying exponential decrease with piconewton forces. These features enable cells to detect ligands or measure surrounding mechanical behaviour within a fraction of a second, much more rapidly than was previously thought
Near-IR absorbing BODIPY derivatives as glutathione-activated photosensitizers for selective photodynamic action

Enhanced spatiotemporal selectivity in photonic sensitization of dissolved molecular oxygen is an important target for improving the potential and the practical applications of photodynamic therapy. Considering the high intracellular glutathione concentrations within cancer cells, a series of BODIPY-based sensitizers that can generate cytotoxic singlet oxygen only after glutathione-mediated cleavage of the electron-sink module were designed and synthesized. Cell culture studies not only validate our design, but also suggest an additional role for the relatively hydrophobic quencher module in the internalization of the photosensitizer. © 2014 Wiley-VCH Verlag GmbH & Co.

Detailed study of SNR G306.3 - 0.9 using XMM-Newton and Chandra observations

Aims. We aim to study the spatial distribution of the physical and chemical properties of the X-ray emitting plasma of the supernova remnant (SNR) G306.3-0.9 in detail to obtain constraints on its ionization stage, the progenitor supernova explosion, and the age of the remnant. Methods. We used combined data from XMM-Newton and Chandra observatories to study the X-ray morphology of G306.3-0.9 in detail. A spatially resolved spectral analysis was used to obtain physical and geometrical parameters of different regions of the remnant. Spitzer infrared observations, available in the archive, were also used to constrain the progenitor supernova and study the environment in which the remnant evolved. Results. The X-ray morphology of the remnant displays a non-uniform structure of semi-circular appearance, with a bright southwest region and very weak or almost negligible X-ray emission in its northern part. These results indicate that the remnant is propagating in a non-uniform environment as the shock fronts are encountering a high-density medium, where enhanced infrared emission is detected. The X-ray spectral analysis of the selected regions shows distinct emission-line features of several metal elements, confirming the thermal origin of the emission. The X-ray spectra are well represented by a combination of two absorbed thermal plasma models: one in equilibrium ionization (VAPEC) with a mean temperature of ∼0.19 keV, and another out of equilibrium ionization (VNEI) at a higher temperature of ∼1.1 or 1.6-1.9 keV. For regions located in the northeast, central, and southwest part of the SNR, we found elevated abundances of Si, S, Ar, Ca, and Fe, typical of ejecta material. The outer regions located northwest and south show values of the abundances above solar but lower than to those found in the central regions. This suggests that the composition of the emitting outer parts of the SNR is a combination of ejecta and shocked material of the interstellar medium. The comparison between the S/Si, Ar/Si, and Ca/Si abundances ratios (1.75, 1.27, and 2.72 in the central region, respectively), favor a Type Ia progenitor for this remnant, a result that is also supported by an independent morphological analysis using the X-ray and 24 μm IR data
Spontaneous and induced dynamic correlations in glass formers. II. Model calculations and comparison to numerical simulations

We study in detail the predictions of various theoretical approaches, in particular, mode-coupling theory (MCT) and kinetically constrained models (KCMs), concerning the time, temperature, and wave vector dependence of multipoint correlation functions that quantify the strength of both induced and spontaneous dynamical fluctuations. We also discuss the precise predictions of MCT concerning the statistical ensemble and microscopic dynamics dependence of these multipoint correlation functions. These predictions are compared to simulations of model fragile and strong glass-forming liquids. Overall, MCT fares quite well in the fragile case, in particular, explaining the observed crucial role of the statistical ensemble and microscopic dynamics, while MCT predictions do not seem to hold in the strong case. KCMs provide a simplified framework for understanding how these multipoint correlation functions may encode dynamic correlations in glassy materials. However, our analysis highlights important unresolved questions concerning the application of KCMs to supercooled liquids
Search for quark compositeness in dijet angular distributions from pp collisions at √s = 7 TeV

The search has been carried out using a data sample corresponding to an integrated luminosity of 2.2 fb -1, recorded by the CMS experiment at the LHC. Normalized dijet angular distributions have been measured for dijet invariant masses from 0.4 TeV to above 3TeV and compared with a variety of contact interaction models, including those which take into account the effects of next-to-leading-order QCD corrections. The data are found to be in agreement with the predictions of perturbative QCD, and lower limits are obtained on the contact interaction scale, ranging from 7.5 up to 14.5 TeV at 95% confidence leve
Measurement of the cross section for the production of a W boson in association with b-jets in pp collisions at √s=7TeV with the ATLAS detector

Artículo escrito por muchos autores, sólo se referencian el que aparece en primer lugar, el nombre del grupo de colaboración y los autores que firman como pertenecientes a la UAMA measurement is presented of the cross section for the production of a W boson with one or two jets, of which at least one must be a b-jet, in pp collisions at √ s = 7 TeV. Production via top decay is not included in the signal definition. The measurement is based on 35 pb−1 of data collected with the ATLAS detector at the LHC. The W + b-jet cross section is defined for jets reconstructed with the antikt clustering algorithm with transverse momentum above 25 GeV and rapidity within ±2.1. The b-jets are identified by reconstructing secondary vertices. The fiducial cross section is measured both for the electron and muon decay channel of the W boson and is found to be 10.2 ± 1.9(stat) ± 2.6(syst) pb for one lepton flavour. The results are compared with next-to-leading order QCD calculations, which predict a cross section smaller than, though consistent with, the measured valueWe thank CERN for the very successful operation of the LHC, as well as the support staff from our institutions without whom ATLAS could not be operated efficiently.

High-resolution imaging of NFG 2346 with GSAOI/GeMS: disentangling the planetary nebula moleular structure to understand its origin and evolution

The Astrophysical Journal 808.2 (2015): 115 reproduced by permission of the AASWe present high spatial resolution (≈60-90 mas) images of the molecular hydrogen emission in the planetary nebula (PN) NGC 2346. The data were acquired during the system verification of the Gemini Multi-conjugate Adaptive Optics System + Gemini South Adaptive Optics Imager. At the distance of NGC 2346, 700 pc, the physical resolution corresponds to ≈56 AU, which is slightly higher than an [N II] image of NGC 2346 that was obtained with the Hubble Space Telescope/WFPC2. With this unprecedented resolution, for the first time we were able to study the structure of the H2 gas within the nebula in detail. We found it to be composed of knots and filaments, which at a lower resolution had appeared to be a uniform torus of material. We explain how the formation of the clumps and filaments in this PN are consistent with a mechanism in which a central hot bubble of nebular gas surrounding the central star has been depressurized, and the thermal pressure of the photoionized region drives the fragmentation of the swept-up shellWe are grateful to R.

Very High Energy outburst of Markarian 501 in May 2009

The very high energy (VHE; E $>$ 100 GeV) blazar Markarian 501 was observed
between April 17 and May 5 (MJD 54938--54956), 2009, as part of an extensive
multi-wavelength campaign from radio to VHE. Strong VHE $\gamma$-ray activity
was detected on May 1st with Whipple and VERITAS, when the flux (E $>$ 400 GeV)
increased to 10 times the pre-flare baseline flux ($3.9{\times 10^{-11}}~{\rm
ph~cm^{-2}~s^{-1}}$), reaching five times the flux of the Crab Nebula. This
coincided with a decrease in the optical polarization and a rotation of the
polarization angle by 15$^{\circ}$. This VHE flare showed a fast flux variation
with an increase of a factor $\sim$4 in 25 minutes, and a falling time of
$\sim$50 minutes. We present the observations of the quiescent state previous
to the flare and of the high state after the flare, focusing on the flux and
spectral variability from Whipple, VERITAS, Fermi-LAT, RXTE, and Swift combined
with optical and radio data.Comment: 13 pages, 10 figures. Accepted for publication in Astronomy and

Azimuthal anisotropy of charged particles with transverse momentum up to
  100 GeV in PbPb collisions at sqrt(s[NN]) = 5.02 TeV

The Fourier coefficients v[2] and v[3] characterizing the anisotropy of the
azimuthal distribution of charged particles produced in PbPb collisions at
sqrt(s[NN]) = 5.02 TeV are measured with data collected by the CMS experiment.
The measurements cover a broad transverse momentum range, 1 < pT < 100 GeV. The
analysis focuses on pT > 10 GeV range, where anisotropic azimuthal
distributions should reflect the path-length dependence of parton energy loss
in the created medium. Results are presented in several bins of PbPb collision
centrality, spanning the 60% most central events. The v[2] coefficient is
measured with the scalar product and the multiparticle cumulant methods, which
have different sensitivities to the initial-state fluctuations. The values of
both methods remain positive up to pT of about 60-80 GeV, in all examined
centrality classes. The v[3] coefficient, only measured with the scalar product
method, tends to zero for pT greater than or equal to 20 GeV. Comparisons
between theoretical calculations and data provide new constraints on the
path-length dependence of parton energy loss in heavy ion collisions and
highlight the importance of the initial-state fluctuations.Comment: Replaced with the published version. Added the journal reference and

Capgras syndrome as a psychiatric manifestation in Parkinson’s disease: a case report and literature review

We present the case of a 58-year-old male patient who had symptoms of anxiety after witnessing a case of social violence in his community in 2005. After that, he presented symptoms of Parkinson Disease and in 2006 we established this as the main diagnosis. In 2009 he presented neuropsychiatric symptoms such as apathy, anhedonia, social isolation, blunted affect, visual\ud
and auditory hallucinations, paranoid delusions, soliloquies, and the false belief that his wife and daughter had been replaced by identical impostors. We established the diagnosis of Capgras Syndrome. This case is clinically relevant because of the presentation of its symptoms, its evolution and its presenting comorbidity
Acute Exposure to Terrestrial Trunked Radio (TETRA) has effects on the electroencephalogram and electrocardiogram, consistent with vagal nerve stimulation.

Background Terrestrial Trunked Radio (TETRA) is a telecommunications system widely used by police and emergency services around the world. The Stewart Report on mobile telephony and health raised questions about possible health effects associated with TETRA signals. This study investigates possible effects of TETRA signals on the electroencephalogram and electrocardiogram in human volunteers. Methods Blinded randomized provocation study with a standardized TETRA signal or sham exposure. In the first of two experiments, police officers had a TETRA set placed first against the left temple and then the upper-left quadrant of the chest and the electroencephalogram was recorded during rest and active cognitive processing. In the second experiment, volunteers were subject to chest exposure of TETRA whilst their electroencephalogram and heart rate variability derived from the electrocardiogram were recorded. Results In the first experiment, we found that exposure to TETRA had consistent neurophysiological effects on the electroencephalogram, but only during chest exposure, in a pattern suggestive of vagal nerve stimulation. In the second experiment, we observed changes in heart rate variability during exposure to TETRA but the electroencephalogram effects were not replicated. Conclusions Observed effects of exposure to TETRA signals on the electroencephalogram (first experiment) and electrocardiogram are consistent with vagal nerve stimulation in the chest by TETRA. However given the small effect on heart rate variability and the lack of consistency on the electroencephalogram, it seems unlikely that this will have a significant impact on health. Long-term monitoring of the health of the police force in relation to TETRA use is on-going
Modulation of mTOR Signalling Triggers the Formation of Stem Cell-like Memory T Cells.

Robust, long-lasting immune responses are elicited by memory T cells that possess properties of stem cells, enabling them to persist long-term and to permanently replenish the effector pools. Thus, stem cell-like memory T (TSCM) cells are of key therapeutic value and efforts are underway to characterize TSCM cells and to identify means for their targeted induction. Here, we show that inhibition of mechanistic/mammalian Target of Rapamycin (mTOR) complex 1 (mTORC1) by rapamycin or the Wnt-β-catenin signalling activator TWS119 in activated human naive T cells leads to the induction of TSCM cells. We show that these compounds switch T cell metabolism to fatty acid oxidation as favoured metabolic programme for TSCM cell generation. Of note, pharmacologically induced TSCM cells possess superior functional features as a long-term repopulation capacity after adoptive transfer. Furthermore, we provide insights into the transcriptome of TSCM cells. Our data identify a mechanism of pharmacological mTORC1 inhibitors, allowing us to confer stemness to human naive T cells which may be significantly relevant for the design of innovative T cell-based cancer immunotherapies
Search for direct pair production of the top squark in all-hadronic final states in proton-proton collisions at √s = 8 TeV with the ATLAS detector

The results of a search for direct pair production of the scalar partner to the top quark using an integrated luminosity of 20.1 fb−1 of proton-proton collision data at s√ = 8 TeV recorded with the ATLAS detector at the LHC are reported. The top squark is assumed to decay via t¯ →tχ¯01 or t¯ →bχ¯±1 →bW(∗)χ¯01 , where χ¯01 (χ¯±1) denotes the lightest neutralino (chargino) in supersymmetric models. The search targets a fully-hadronic final state in events with four or more jets and large missing transverse momentum. No significant excess over the Standard Model background prediction is observed, and exclusion limits are reported in terms of the top squark and neutralino masses and as a function of the branching fraction of t¯ →tχ¯01 . For a branching fraction of 100%, top squark masses in the range 270–645 GeV are excluded for χ¯01 masses below 30 GeV. For a branching fraction of 50% to either t¯ →tχ¯01 or t¯ →bχ¯±1 , and assuming the χ¯±1 mass to be twice the χ¯01 mass, top squark masses in the range 250–550 GeV are excluded for χ¯01 masses below 60 GeV.National Science Foundation (U.S.)United States.

Publishing and impact criteria, and their bearing on translation studies : in search of comparability

This paper questions the current concept of quality as used in research assessment rankings and peer review, with special reference to the link often established between impact and the way this impact is measured in the form of citation counting. Taking translation studies as a case study, we will offer a two-level approach to reveal both the macro- and micro-level biases that exist in this regard. We will first review three key aspects related to the idea of the quality of publications, namely peer review, journal indexing, and journal impact factor. We will then pinpoint some of the main macro-level problems regarding current practices and criteria as applied to translation studies, such as Thomson Reuters World of Science's journal coverage, citation patterns, and publication format. Next we will provide a micro-textual and practical perspective, focusing on citation counts and suggesting a series of corrective measures to increase comparabilit
