The integrated luminosities used are 4.7 and 20.3 fb<sup>â\u88\u921</sup> from pp collisions at (Formula presented.) and 8 TeV, respectively. The processes considered are associated (W/Z)H production, where W â\u86\u92 eÎ½/Î¼Î½, Z â\u86\u92 ee/Î¼Î¼ and Z â\u86\u92 Î½Î½. The observed (expected) deviation from the background-only hypothesis corresponds to a significance of 1.4 (2.6) standard deviations and the ratio of the measured signal yield to the Standard Model expectation is found to be Î¼ = 0.52 Â± 0.32 (stat.) Â± 0.24 (syst.) for a Higgs boson mass of 125.36 GeV. The analysis procedure is validated by a measurement of the yield of (W/Z)Z production with (Formula presented.) in the same final states as for the Higgs boson search, from which the ratio of the observed signal yield to the Standard Model expectation is found to be 0.74 Â± 0.09 (stat.) Â± 0.14 (syst.).[Figure not available: see fulltext.]
Being Transported into the Unknown: How Patients Experience the Route to the Operation Room

When you are admitted to a hospital, you enter an often-unfamiliar environment. From a person, you suddenly become a patient. Especially when being transported in a bed, you lose control over where you go and how you interact with the space around you. Many people feel anxious and vulnerable under these conditions. Often the built environment adds to this confusion, whereas it should support patients during their hospital experience. To explore the relation between motion and space, we present a concise literature review on mobile and spatial experience, and sketch the theoretical background on researching motion. To actually study the impact of space and spatial elements on patients' mobile hospital experience, we interviewed with 12 patients admitted to the day ward of a general city hospital. The interviews were supported by videos of the transport, which the researchers had previously made. Studying the role of motion in patients spatial experience of the hospital appeared not to be an easy task. Both methodologically and content wise, we encountered some challenges in bringing to the surface and unravelling those experiences linked to spatial aspects. Despite what one could expect, being moved in a bed does not reduce but rather expands patients' sensory perception. An important interrelation between space, time and people, especially during the transport, was found. By designing space architects thus may have a strong influence on time perception and people interactions.status: publishe
Signature of an h1 state in the J/ψ→ηh1→ηK⁎0K⎯⎯⎯⁎0 decay

The BES data on the J/ψ→ηK⁎0K⎯⎯⎯⁎0 reaction show a clear enhancement in the K⁎0K⎯⎯⎯⁎0 mass distribution close to the threshold of this channel. Such an enhancement is usually a signature of an L=0 resonance around threshold, which in this case would correspond to an h1 state with quantum numbers IG(JPC)=0−(1+−) . A state around 1800MeV results from the interaction of the K⁎K⎯⎯⎯⁎ using the local hidden gauge approach. We show that the peak observed in J/ψ→ηK⁎0K⎯⎯⎯⁎0 naturally comes from the creation of this h1 state with mass and width around 1830MeV and 110MeV , respectively. A second analysis, model independent, corroborates the first result, confirming the relationship of the enhancement in the invariant mass spectrum with the h1 resonance
Combined results of searches for the standard model Higgs boson in pp collisions at s=7 TeV

This article is published Open Access, is distributed under the terms of the Creative Commons Attribution License 3.0.-- et al.Combined results are reported from searches for the standard model Higgs boson in proton-proton collisions at s=7 TeV in five Higgs boson decay modes: γγ, bb, ττ, WW, and ZZ. The explored Higgs boson mass range is 110-600 GeV. The analysed data correspond to an integrated luminosity of 4.6-4.8 fb -1. The expected excluded mass range in the absence of the standard model Higgs boson is 118-543 GeV at 95% CL. The observed results exclude the standard model Higgs boson in the mass range 127-600 GeV at 95% CL, and in the mass range 129-525 GeV at 99% CL. An excess of events above the expected standard model background is observed at the low end of the explored mass range making the observed limits weaker than expected in the absence of a signal. The largest excess, with a local significance of 3.1σ, is observed for a Higgs boson mass hypothesis of 124 GeV. The global significance of observing an excess with a local significance ≥3.1σ anywhere in the search range 110-600 (110-145) GeV is estimated to be 1.5σ(2.1σ). More data are required to ascertain the origin of the observed excess.Acknowledge support from: FMSR (Austria); FNRS and FWO (Belgium); CNPq, CAPES, FAPERJ, and FAPESP\ud

Cardioprotective mechanism of S-nitroso-N-acetylcysteine via S-nitrosated betadrenoceptor-2 in the LDLr-/- mice

Previous studies from our group have demonstrated the protective effect of S-nitroso-N-acetylcysteine (SNAC) on the cardiovascular system in dyslipidemic LDLr-/- mice that develop atheroma and left ventricular hypertrophy after 15 days on a high fat diet. We have shown that SNAC treatment attenuates plaque development via the suppression of vascular oxidative stress and protects the heart from structural and functional myocardial alterations, such as heart arrhythmia, by reducing cardiomyocyte sensitivity to catecholamines. Here we investigate the ability of SNAC to modulate oxidative stress and cell survival in cardiomyocytes during remodeling and correlation with beta(2)-AR signaling in mediating this protection. Ventricular superoxide (O-2(-)) and hydrogen peroxide (H2O2) generation was measured by HPLC methods to allow quantification of dihydroethidium (DHE) products. Ventricular histological sections were stained using terminal dUTP nick-end labeling (TUNEL) to identify nuclei with DNA degradation (apoptosis) and this was confirmed by Western blot for cleaved caspase-3 and caspase-7 protein expression. the findings show that O-2(-) and H2O2 production and also cell apoptosis were increased during left ventricular hypertrophy (LVH). SNAC treatment reduced oxidative stress during on cardiac remodeling, measured by decreased H2O2 and O-2(-) production (65% and 52%, respectively), and a decrease in the ratio of p-Ser1177 eNOS/total eNOS. Left ventricle (LV) from SNAC-treated mice revealed a 4-fold increase in beta(2)-AR expression associated with coupling change to Gi; beta(2)-ARs-S-nitrosation (beta(2)-AR-SNO) increased 61%, while apoptosis decreased by 70%. These results suggest that the cardio-protective effect of SNAC treatment is primarily through its anti-oxidant role and is associated with beta(2)-ARs overexpression and beta(2)-AR-SNO via an anti-apoptotic pathway.

Urinary neutrophil gelatinase-associated lipocalin levels reflect damage to glomeruli, proximal tubules, and distal nephrons.

Published online 1 October 2008Urinary neutrophil gelatinase-associated lipocalin (Ngal or lipocalin 2) is a very early and sensitive biomarker of kidney injury. Here we determined the origin and time course of Ngal appearance in several experimental and clinically relevant renal diseases. Urinary Ngal levels were found to be markedly increased in lipoatrophic- and streptozotocin-induced mouse models of diabetic nephropathy. In the latter mice, the angiotensin receptor blocker candesartan dramatically decreased urinary Ngal excretion. The reabsorption of Ngal by the proximal tubule was severely reduced in streptozotocin-induced diabetic mice, but upregulation of its mRNA and protein in the kidney was negligible, compared to those of control mice, suggesting that increased urinary Ngal was mainly due to impaired renal reabsorption. In the mouse model of unilateral ureteral obstruction, Ngal protein synthesis was dramatically increased in the dilated thick ascending limb of Henle and N was found in the urine present in the swollen pelvis of the ligated kidney. Five patients with nephrotic syndrome or interstitial nephritis had markedly elevated urinary Ngal levels at presentation, but these decreased in response to treatment. Our study shows that the urinary Ngal level may be useful for monitoring the status and treatment of diverse renal diseases reflecting defects in glomerular filtration barrier, proximal tubule reabsorption, and distal nephrons
Tourism Demand Modelling and Forecasting: A Review of Recent Research

This paper reviews the published studies on tourism demand modelling and forecasting since 2000. One of the key findings of this review is that the methods used in analysing and forecasting the demand for tourism have been more diverse than those identified by other review articles. In addition to the most popular time-series and econometric models, a number of new techniques have emerged in the literature. However, as far as the forecasting accuracy is concerned, the study shows that there is no single model that consistently outperforms other models in all situations. Furthermore, this study identifies some new research directions, which include improving the forecasting accuracy through forecast combination; integrating both qualitative and quantitative forecasting approaches, tourism cycles and seasonality analysis, events' impact assessment and risk forecasting.

Dike propagation within active central volcanic edifices: constraints from Somma-Vesuvius, Etna and analogue models

Dikes within stratovolcanoes are commonly expected to have radial patterns. However, other patterns may also be also found, due to regional stresses, magmatic reservoirs, topographic variations. Here we investigate dike patterns within volcanic edifices, by studying dike and fissure complexes at Somma-Vesuvius and Etna (Italy) and using analogue models. At the surface, the dikes and fissures show a radial configuration. At depths of tens to several hundreds of m, in areas exposed by erosion, tangential and oblique dikes are also present. Analogue models indicate that dikes approaching the flanks of cones, regardless of their initial orientation, reorient to become radial (parallel to the maximum gravitational stress). This reorientation is a significant process in shallow magma migration and may also control the emplacement of dike-fed fissures reaching the lower slopes of the volcano
Recovering the epipolar direction from two affine views of a planar object

The mainstream approach to estimate epipolar geometry from two views requires matching the projections of at least 4 non-coplanar points in the scene, assuming a full projective camera model. Our work deviates from this in three respects: affine camera, planar scene and active contour tracking instead of point matching. Using results in Projective Geometry, we prove that the affine epipolar direction can be recovered provided camera motion is free of cyclorotation. A setup consisting of a Staubli robot holding a planar object in front of a camera is used to obtain calibrated image streams, which are used as ground truth to evaluate the performance of the method, and to test its limiting conditions in practice. The fact that our method (applicable to planar, poorly textured scenes) and the Gold Standard algorithm (applicable to highly textured scenes with significant relief) produce comparable results shows the potential of our proposal.Peer Reviewe

Driven holographic CFTs.

We study the dynamical evolution of strongly coupled field theories, initially in thermal equilibrium, under the influence of an external driving force. We model the field theory holographically using classical gravitational dynamics in an asymptotically AdS spacetime. The system is driven by a source for a (composite) scalar operator. We focus on a scenario where the external source is periodic in time and chart out the response of several observables. We find an interesting phase structure in the response as a function of the amplitude of the source and driving frequency. Specifically the system transitions from a dissipation dominated phase, via a dynamical crossover to a highly resonant amplification phase. The diagnostics of these phases include the response of the operator in question, entropy production, energy fluctuations, and the temporal change of entanglement entropy for small subsystems. We comment on evidence for a potential phase transition in the energy fluctuations of the system
Glacial Lake Pickering : stratigraphy and chronology of a proglacial lake dammed by the North Sea Lobe of the British–Irish Ice Sheet.

We report the first chronology, using four new optically stimulated luminescence dates, on the sedimentary record of Glacial Lake Pickering, dammed by the North Sea Lobe of the British–Irish Ice Sheet during the Dimlington Stadial (24–11 ka cal BP). Dates range from 17.6 ± 1.0 to 15.8 ± 0.9 ka for the sedimentation of the Sherburn Sands at East Heslerton, which were formed by multiple coalescing alluvial fans prograding into the falling water levels of the lake and fed by progressively larger volumes of debris from the Wolds. Fan formation ceased ∼15.8 ka, at a time when permafrost was degrading and nival-fed streams were no longer capable of supplying sediment to the fans. A further age of 10.1 ± 0.7 ka dates the reworking of coversand into the early part of the Holocene, immediately post-dating Younger Dryas periglacial structures. A 45-m lake level dates to ∼17.6 ka, when the North Sea Lobe was already in retreat, having moved eastward of the Wykeham Moraine; it stood further east at the Flamborough Moraine by ∼17.3 ka. The highest (70 m) lake level and the occupation of the Wykeham Moraine date to an earlier phase of the North Sea Lobe occupation of the Vale of Pickering
Production and characterisation of a dual species magneto-optical trap of cesium and ytterbium\ud

We describe an apparatus designed to trap and cool a Yb and Cs mixture. The apparatus consists of a dual species effusive oven source, dual species Zeeman slower, magneto-optical traps in a single ultra-high vacuum science chamber, and the associated laser systems. The dual species Zeeman slower is used to load sequentially the two species into their respective traps. Its design is flexible and may be adapted for other experiments with different mixtures of atomic species. The apparatus provides excellent optical access and can apply large magnetic bias fields to the trapped atoms. The apparatus regularly produces 108 Cs atoms at 13.3 μK in an optical molasses, and 109174Y b atoms cooled to 22 μK in a narrowband magneto-optical trap
Lagrangian and Hamiltonian structures in an integrable hierarchy and space-time duality

We define and illustrate the novel notion of dual integrable hierarchies, on the example of the nonlinear Schr¨odinger (NLS) hierarchy. For each integrable nonlinear evolution equation (NLEE) in the hierarchy, dual integrable structures are characterized by the fact that the zerocurvature representation of the NLEE can be realized by two Hamiltonian formulations stemming from two inequivalent Poisson structures and two distinct Hamiltonians. This is different from the standard bi-Hamiltonian structure. One is well-known and based on the standard Poisson structure for NLS. The other one is new and based on a different Poisson structure at each level of the hierarchy, yielding the corresponding NLEE as a space evolution equation. We emphasize the role of the Lagrangian formulation as a unifying framework for deriving both Poisson structures, using ideas from covariant field theory. One of our main results is to show that the two matrices of the Lax pair satisfy the same form of ultralocal Poisson algebra (up to a sign) characterized by an r-matrix structure, whereas traditionally only one of them is involved in the classical rmatrix method. We construct explicit dual hierarchies of Hamiltonians, and Lax representations of the triggered dynamics, from the monodromy matrices of either Lax matrix. An appealing procedure to build a multi-dimensional lattice of Lax pair, through successive uses of the dual Poisson structures, is briefly introduced
Correlations between jets and charged particles in PbPb and pp
  collisions at sqrt(s[NN]) = 2.76 TeV

The quark-gluon plasma is studied via medium-induced changes to correlations
between jets and charged particles in PbPb collisions compared to pp reference
data. This analysis uses data sets from PbPb and pp collisions with integrated
luminosities of 166 inverse microbarns and 5.3 inverse picobarns, respectively,
collected at sqrt(s[NN]) = 2.76 TeV. The angular distributions of charged
particles are studied as a function of relative pseudorapidity (Delta eta) and
relative azimuthal angle (Delta phi) with respect to reconstructed jet
directions. Charged particles are correlated with all jets with transverse
momentum (pt) above 120 GeV, and with the leading and subleading jets (the
highest and second-highest in pt, respectively) in a selection of back-to-back
dijet events. Modifications in PbPb data relative to pp reference data are
characterized as a function of PbPb collision centrality and charged particle
pt. A centrality-dependent excess of low-pt particles is present for all jets
studied, and is most pronounced in the most central events. This excess of
low-pt particles follows a Gaussian-like distribution around the jet axis, and
extends to large relative angles of Delta eta approximately 1 and Delta phi

Yang-Baxter invariance of the Nappi-Witten model

We study Yang-Baxter deformations of the Nappi-Witten model with a prescription invented by Delduc, Magro and Vicedo. The deformations are specified by skew-symmetric classical r-matrices satisfying (modified) classical Yang-Baxter equations. We show that the sigma-model metric is invariant under arbitrary deformations (while the coefficient of B-field is changed) by utilizing the most general classical r-matrix. Furthermore, the coefficient of B-field is determined to be the original value from the requirement that the one-loop β-function should vanish. After all, the Nappi-Witten model is the unique conformal theory within the class of the Yang-Baxter deformations preserving the conformal invariance
Search for new phenomena in final states with large jet multiplicities and missing transverse momentum using root s=7 TeV pp collisions with the ATLAS detector

Results are presented of a search for any particle(s) decaying to six or more jets in association with missing transverse momentum. The search is performed using 1.34 fb(-1) of root s = 7TeV proton-proton collisions recorded by the ATLAS detector during 2011. Data-driven techniques are used to determine the backgrounds in kinematic regions that require at least six, seven or eight jets, well beyond the multiplicities required in previous analyses. No evidence is found for physics beyond the Standard Model. The results are interpreted in the context of a supersymmetry model (MSUGRA/CMSSM) where they extend previous constraints
Spanwise structure and scale growth in turbulent boundary layers

Spanwise structure and growth mechanisms in a turbulent boundary layer are investigated experimentally. PIV measurements are obtained in the streamwise???spanwise (x???z) plane from the buffer layer to the top of the logarithmic region at Re(??) = 1015 and 7705. The dominant motions of the flow are shown to be large-scale regions of momentum deficit elongated in the streamwise direction. Throughout the logarithmic layer, the regions are consistently bordered by vortices organized in the streamwise direction, offering strong support for a vortex packet model. Additionally, evidence is presented for the existence and organization of hairpin vortices in the region y^+ < 60. Statistical evidence is also presented for two important aspects of the vortex packet paradigm: vortex organization in the streamwise direction, and the clear association of the hairpin signature with local minima in streamwise velocity.  Several spanwise length scales are shown to vary linearly with distance from the wall, revealing self-similar growth of spanwise structure in an average sense. Inspection of the data, however, suggests that individual structures do not grow strictly self-similarly in time. It is proposed that additional scale growth occurs by the merging of vortex packets on an eddy-by-eddy basis via a vortex re-connection mechanism similar to that suggested by Wark & agib (1989). The proposed mechanism provides a link between vortex-pairing concepts and the observed coalescence of streaky low-speed regions in the inner layer.published or submitted for publicationis peer reviewe
