Beauty production in pp collisions at √s=2.76 TeV measured via semi-electronic decays

The ALICE Collaboration at the LHC reports measurement of the inclusive production cross section of electrons from semi-leptonic decays of beauty hadrons with rapidity |y|<0.8 and transverse momentum 1<pT<10 GeV/c, in pp collisions at √=2.76 TeV. Electrons not originating from semi-electronic decay of beauty hadrons are suppressed using the impact parameter of the corresponding tracks. The production cross section of beauty decay electrons is compared to the result obtained with an alternative method which uses the distribution of the azimuthal angle between heavy-flavour decay electrons and charged hadrons. Perturbative QCD predictions agree with the measured cross section within the experimental and theoretical uncertainties. The integrated visible cross section, σb→e=3.47±0.40(stat)−1.33+1.12(sys)±0.07(norm) μb, was extrapolated to full phase space using Fixed Order plus Next-to-Leading Log (FONLL) calculations to obtain the total bb¯ production cross section, σbb¯=130±15.1(stat)−49.8+42.1(sys)−3.1+3.4(extr)±2.5(norm)±4.4(BR) μb
Electroweak corrections to squark-antisquark production at the LHCb

We present the calculation of the electroweak corrections for squark-antisquark pair production at the LHC within the Minimal Supersymmetric Standard Model. Taking into account all possible chirality and light-flavor configurations, we evaluate the NLO EW corrections, which are of $\mathcal{O}\left({\alpha}_s^2\alpha \right)$, as well as the subleading tree-level contributions of $\mathcal{O}\left({\alpha}_s\alpha \right)$ and $\mathcal{O}\left({\alpha}^2\right)$ . Numerical results are presented for several scans in the SUSY parameter space and relevant differential distributions are investigated. The impact of the electroweak corrections is nonnegligible and strongly depends on the chirality configuration of the produced squarks. Our analysis includes a discussion of photon-gluon initiated processes with a focus on the impact of the corresponding large PDF uncertainties
Nuclear charge radii of potassium isotopes beyond N = 28

We report on the measurement of optical isotope shifts for 38,39,42,44,46–51K relative to 47K from which changes in the nuclear mean square charge radii across the N = 28 shell closure are deduced. The investigation was carried out by bunched-beam collinear laser spectroscopy at the CERN-ISOLDE radioactive ion-beam facility. Mean square charge radii are now known from 37K to 51K, covering all νf7/2-shell as well as all νp3/2-shell nuclei. These measurements, in conjunction with those of Ca, Cr, Mn and Fe, provide a first insight into the Z dependence of the evolution of nuclear size above the shell closure at N = 28.status: publishe
Higher spin currents in Wolf space. Part I

For the $ \mathcal{N} $ = 4 superconformal coset theory described by $ \frac{{\mathrm{SU}\left( {N+2\ } \right)}}{{\mathrm{SU}\left( {N\ } \right)}} $ (that contains a Wolf space) with N = 3, the $ \mathcal{N} $ = 2 WZW affine current algebra with constraints is obtained. The 16 generators of the large $ \mathcal{N} $ = 4 linear superconformal algebra are described by those WZW affine currents explicitly. By factoring out four spin- $ \frac{1}{2} $ currents and the spin-1 current from these 16 generators, the remaining 11 generators (spin-2 current, four spin- $ \frac{3}{2} $ currents, and six spin-1 currents) corresponding to the large $ \mathcal{N} $ = 4 nonlinear superconformal algebra are obtained. Based on the recent work by Gaberdiel and Gopakumar on the large $ \mathcal{N} $ = 4 holography, the extra 16 currents, with spin contents $ \left( {1,\frac{3}{2},\frac{3}{2},2} \right),\  \left( {\frac{3}{2},2,2,\frac{5}{2}} \right),\  \left( {\frac{3}{2},2,2,\frac{5}{2}} \right) $ , and $ \left( {2,\frac{5}{2},\frac{5}{2},3} \right) $ described in terms of $ \mathcal{N} $ = 2 multiplets, are obtained and realized by the WZW affine currents. As a first step towards $ \mathcal{N} $ = 4 $ \mathcal{W} $ algebra (which is NOT known so far), the operator product expansions (OPEs) between the above 11 currents and these extra 16 higher spin currents are found explicitly. It turns out that the composite fields with definite U(1) charges, made of above (11 + 16) currents (which commute with the Wolf space subgroup SU( N = 3) × SU(2) × U(1) currents), occur in the right hand sides of these OPEs
Final charged-lepton angular distribution and possible anomalous top-quark couplings in pp→tt¯X→ℓ+X′

Possible anomalous (or nonstandard) top-quark interactions with the gluon and those with the W boson induced by SU(3)×SU(2)×U(1) gauge-invariant dimension-6 effective operators are studied in pp→tt¯X→ℓ+X′ ( ℓ=e or μ ) at the Large Hadron Collider (LHC). The final charged-lepton ( ℓ+ ) angular distribution is first computed for nonvanishing nonstandard top-gluon and top- W couplings with a cut on its transverse momentum. The optimal-observable procedure is then applied to this distribution in order to estimate the expected statistical uncertainties in measurements of those couplings that contribute to this process in the leading order
Leptogenesis in an SU(5)×A5 golden ratio flavour model

In this paper we discuss a minor modification of a previous SU(5)×A5 flavour model which exhibits at leading order golden ratio mixing and sum rules for the heavy and the light neutrino masses. Although this model could predict all mixing angles well it fails in generating a sufficient large baryon asymmetry via the leptogenesis mechanism. We repair this deficit here, discuss model building aspects and give analytical estimates for the generated baryon asymmetry before we perform a numerical parameter scan. Our setup has only a few parameters in the lepton sector. This leads to specific constraints and correlations between the neutrino observables. For instance, we find that in the model considered only the neutrino mass spectrum with normal mass ordering and values of the lightest neutrino mass in the interval 10–18 meV are compatible with the current data on the neutrino oscillation parameters. With the introduction of only one NLO operator, the model can accommodate successfully simultaneously even at 1 σ level the current data on neutrino masses, on neutrino mixing and the observed value of the baryon asymmetry
Strings from 3D gravity: asymptotic dynamics of AdS 3 gravity with free boundary conditions

Pure three-dimensional gravity in anti-de Sitter space can be formulated as an SL(2 , R ) × SL(2 , R ) Chern-Simons theory, and the latter can be reduced to a WZW theory at the boundary. In this paper we show that AdS 3 gravity with free boundary conditions is described by a string at the boundary whose target spacetime is also AdS 3 . While boundary conditions in the standard construction of Coussaert, Henneaux, and van Driel are enforced through constraints on the WZW currents, we find that free boundary conditions are partially enforced through the string Virasoro constraints
Abelian reductions of deformed N=4 SYM

Following the work in [1] , where the massive ABJM model in 2+1 dimensions was shown to have an abelian reduction to the relativistic Landau–Ginzburg, and motivated by the implications for condensed matter through AdS/CFT, we show that a FI deformation of N=4 SYM in 3+1 dimensions with a mass term can also be reduced to a relativistic Landau–Ginzburg model, with the possibility of coupling it to a real scalar, whereas the simply mass deformed N=4 SYM reduces only to a massive ϕ4 model (scalar QED) coupled to a real scalar. We study the classical solutions of the model, in particular vortex solutions
Born–Infeld electrodynamics in very special relativity

In this work we discuss the properties of a modified Born–Infeld electrodynamics in the framework of very special relativity (VSR). This proposal allows us to study VSR mass effects in a gauge-invariant context of nonlinear electrodynamics. It is analyzed in detail the electrostatic solutions for two different cases, as well as the VSR dispersion relations are found to be of a massive particle with nonlinear modifications. Afterwards, the field energy and static potential are computed, in the latter we find from the VSR contribution a novel long-range 1/L3 correction to the Coulomb potential, in contrast to the 1/L5 correction of the usual Born–Infeld theory
Charged scalar perturbations around Garfinkle–Horowitz–Strominger black holes

We examine the stability of the Garfinkle–Horowitz–Strominger (GHS) black hole under charged scalar perturbations. Employing the appropriate numerical methods, we show that the GHS black hole is always stable against charged scalar perturbations. This is different from the results obtained in the de Sitter and anti-de Sitter black holes. Furthermore, we argue that in the GHS black hole background there is no amplification of the incident charged scalar wave to cause the superradiance, so that the superradiant instability cannot exist in this spacetime
Thermopower and thermoelectric power factor of Zk parafermion quantum dots

Using the conformal field theory approach to the thermoelectric characteristics of fractional quantum Hall states, previously developed in Georgiev (2015)  [10] , we show that the thermoelectric power factor of Coulomb-blockaded islands, realized by point contacts in Fabry–Pérot interferometers in the Zk parafermion Hall states, could give reliable signatures for distinguishing the topological orders of different quantum Hall states having identical electric properties. For example, while the conductance peak patterns in the Coulomb blockade regime for such states are practically indistinguishable for vn≪vc even at finite temperature, where vn and vc are the Fermi velocities of the neutral and charged modes respectively, the power factors PT of the corresponding states are much more sensitive to the neutral modes. In particular, the smaller r=vn/vc the bigger the asymmetries in the power factor which combined with the thermal broadening of the conductance peaks due to the neutral modes' multiplicities could give us the ultimate tool to figure out which of the competing quantum Hall universality classes are indeed realized in the experiments. We give a complete description of the power factor profiles in the Z3 and Z4 parafermion states with arbitrary number of quasiparticles localized in the bulk which could be useful for comparison with the experiments
Charge exchange operators sum rules and proton–neutron T=0 and T=1 pairing interactions

21 pages, 3 tables.--PACS nrs.:23.40.Hc, 21.60.-n, 27.40.+z.--Available online on Aug 8, 2003.--ArXiv pre-print available at: http://arxiv.org/abs/nucl-th/0304024v2We study sum rules for charge exchange operators of the Gamow–Teller and Fermi type and explore what can be learned from them about proton–neutron pairing in T=0 and T=1 channels. We consider both energy weighted (EWSR) and non-energy weighted (NEWSR) sum rules. We use a schematic Hamiltonian to stress the distinctive roles of T=1 and T=0 pair interactions and correlations in the sum rules. Numerical results for 44Ti are presented for both schematic and realistic interactions.This work was partially supported by MCyT (Spain) under contract numbers PB98-0676 and BFM2002-03562, by a US Department of Energy Grant No. DE-FG02-95ER-40940 and by a NATO Linkage Grant PST 978158.Peer reviewe
Optical Properties of Self-Assembled GaxIn1–xAs/InP Quantum Wires

8 páginas, 2 figuras, 1 tabla.-- PACS numbers  73.21.Hb; 78.55.Cr; 78.67.Lt; S7.11; S7.12.Temperature dependent photoluminescence studies have been carried out on several samples containing self-assembled GaxIn1–xAs/InP quantum wires. A red-shift of the emission wavelength is observed when increasing the Ga content in the alloy, but the overall optical quality decreases. In the case of x = 0.15, the photoluminescence is not sensible to temperature and the emission band is conserved until room temperature is reached, which could be explained if the nanostructures are considered to be almost amorphous.This work has been supported by the spanish CICYT under the\ud

Sociocultural--Geospatial Anthropological Portal (SC-GAP): Enhanced Sociocultural Understanding Through Crowdsourced Service Member Narratives

The article of record as published may be found at http://dx.doi.org/10.1016/j.promfg.2015.07.533Despite the Department of Defense’s (DoD) many investments directed toward developing and fielding programs designed to
advance sociocultural knowledge, the DoD nonetheless lacks a shared repository in which all entities can aggregate, visualize,
and share sociocultural data across the enterprise. A gap analysis of DoD’s desired and actual states of achieving and
implementing a sociocultural understanding reveals three main shortcomings: a data gap, a repository gap, and a collaboration
gap. As a consequence, we created a proof of concept, enterprise solution for DoD that bridges the overall sociocultural gap by
harnessing the overlooked and untapped potential of today’s deployed DoD service members, who over the course of their daily
duties, are exposed to various populations’ cultures. Service member observations and interpretations of service members’
interactions form an untapped set of operationally relevant sociocultural data. The existing wellspring of sociocultural
information needs only be collected and indexed using a framework derived from the Five Operational Culture Dimensions
model. Residing on a geodatabase and interfaced via a custom multi-client supported web-based Geographic Information System
(GIS), this framework integrates the collected data comprised of service member narratives with the greater Joint Force thereby
creating a dynamic and collaborative sociocultural living repository. Combining an anthropologically sound framework that is
operationally relevant with the capabilities of GIS results in a solution that will allow DoD personnel to uniformly populate,
visualize, and share near real-time cultural data relevant to military operations across all services and agencies. This DoD
enterprise solution has the potential to enhance the Nation’s armed forces’ strategic performance through the application of
culturally adept military powe
Assessing the solvation mechanism of C-60(OH)(24) in aqueous solution

Using molecular dynamics simulations, combined with the thermodynamic integration algorithm, we examine the hydration mechanism of C-60(OH)(24) under ambient conditions. We analyze its structural features, dynamics, and hydration free energy. Our results have been compared with a pristine fullerene aqueous system. Despite the number of hydroxyl groups in the fullerenol, its hydration entropy is rather similar to that calculated for C-60. On the other hand, we have calculated a dramatically negative free energy of about -354 kJ/mol for the fullerenol, whereas pure fullerene presents a positive value of about 59 kJ/mol. On this basis, our study indicates that the hydration of C-60(OH)(24) is guided by an enthalpy-driven process. (C) 2011 Elsevier B.V.

Process of pyroplastic shaping for special-purpose porcelain stoneware tiles

A novel technique to manufacture special-purpose tiles (i.e. trim pieces, steps, skirting boards, etc.) has been recently developed on the basis of a pyroplastic shaping of porcelain stoneware tiles. This innovative process involves a second firing, peaking at temperatures close to those of sintering, whose effect was investigated by comparing industrially-manufactured tiles before and after pyroplastic shaping. Characterization by XRF, XRPD, SEM and standard testing (ISO 10545) put in evidence that pyroplastic bending induced little changes in the water absorption and bulk density values, as in phase composition. Limited variations occurring to closed porosity, mechanical strength and microstructure do not significantly affect the overall technological performance of the special-purpose tiles, which is substantially the same of the original porcelain stoneware tiles. A detailed microstructural characterization was performed for the first time on porcelain stoneware tiles: coarse grains (>10 ?m) represent 10-15% of total volume, while fine-grained crystals, dispersed in the glassy phase, amount from 30% to 65% of the viscous matrix. The pyroplastic behaviour was found to depend in a complex way on such microstructural and compositional features, which deeply affect the effective viscosity of the matrix
Unified theory of exactly and quasiexactly solvable “discrete” quantum mechanics. I. Formalism

We present a simple recipe to construct exactly and quasiexactly solvable Hamiltonians in one-dimensional “discrete” quantum mechanics, in which the Schrödinger equation is a difference equation. It reproduces all the known ones whose eigenfunctions consist of the Askey scheme of hypergeometric orthogonal polynomials of a continuous or a discrete variable. The recipe also predicts several new ones. An essential role is played by the sinusoidal coordinate, which generates the closure relation and the Askey–Wilson algebra together with the Hamiltonian. The relationship between the closure relation and the Askey–Wilson algebra is clarified
Generation of Alveolar Epithelial Spheroids via Isolated Progenitor Cells from Human Pluripotent Stem Cells.

ヒトiPS細胞から肺胞上皮細胞を分化誘導し、単離する方法を確立 -肺の再生/創薬研究につながる大きな一歩-. 京都大学プレスリリース. 2014-08-22.No methods for isolating induced alveolar epithelial progenitor cells (AEPCs) from human embryonic stem cells (hESCs) and induced pluripotent stem cells (hiPSCs) have been reported. Based on a study of the stepwise induction of alveolar epithelial cells (AECs), we identified carboxypeptidase M (CPM) as a surface marker of NKX2-1(+) "ventralized" anterior foregut endoderm cells (VAFECs) in vitro and in fetal human and murine lungs. Using SFTPC-GFP reporter hPSCs and a 3D coculture system with fetal human lung fibroblasts, we showed that CPM(+) cells isolated from VAFECs differentiate into AECs, demonstrating that CPM is a marker of AEPCs. Moreover, 3D coculture differentiation of CPM(+) cells formed spheroids with lamellar-body-like structures and an increased expression of surfactant proteins compared with 2D differentiation. Methods to induce and isolate AEPCs using CPM and consequently generate alveolar epithelial spheroids would aid human pulmonary disease modeling and regenerative medicine
Randomized Trial of Complete Versus Lesion-Only Revascularization in Patients Undergoing Primary Percutaneous Coronary Intervention for STEMI and Multivessel Disease: The CvLPRIT Trial.

Background\ud
The optimal management of patients found to have multivessel disease while undergoing primary percutaneous coronary intervention (P-PCI) for ST-segment elevation myocardial infarction is uncertain.\ud
\ud
Objectives\ud
CvLPRIT (Complete versus Lesion-only Primary PCI trial) is a U.K. open-label randomized study comparing complete revascularization at index admission with treatment of the infarct-related artery (IRA) only.\ud
\ud
Methods\ud
After they provided verbal assent and underwent coronary angiography, 296 patients in 7 U.K. centers were randomized through an interactive voice-response program to either in-hospital complete revascularization (n = 150) or IRA-only revascularization (n = 146). Complete revascularization was performed either at the time of P-PCI or before hospital discharge. Randomization was stratified by infarct location (anterior/nonanterior) and symptom onset (≤3 h or >3 h). The primary endpoint was a composite of all-cause death, recurrent myocardial infarction (MI), heart failure, and ischemia-driven revascularization within 12 months.\ud
\ud
Results\ud
Patient groups were well matched for baseline clinical characteristics. The primary endpoint occurred in 10.0% of the complete revascularization group versus 21.2% in the IRA-only revascularization group (hazard ratio: 0.45; 95% confidence interval: 0.24 to 0.84; p = 0.009). A trend toward benefit was seen early after complete revascularization (p = 0.055 at 30 days). Although there was no significant reduction in death or MI, a nonsignificant reduction in all primary endpoint components was seen. There was no reduction in ischemic burden on myocardial perfusion scintigraphy or in the safety endpoints of major bleeding, contrast-induced nephropathy, or stroke between the groups.\ud
\ud
Conclusions\ud
In patients presenting for P-PCI with multivessel disease, index admission complete revascularization significantly lowered the rate of the composite primary endpoint at 12 months compared with treating only the IRA. In such patients, inpatient total revascularization may be considered, but larger clinical trials are required to confirm this result and specifically address whether this strategy is associated with improved survival.

Salivary cortisol and testosterone responses to high-intensity cycling before and after an 11-day intensified training period

This is an Accepted Manuscript of an article published by Taylor & Francis in  Journal of Sports Sciences  on 28th May 2013, available online: http://wwww.tandfonline.com/10.1080/02640414.2013.792952This study examined salivary cortisol and testosterone responses to two, different high-intensity, ~30-min cycles separated by 2 h rest before and after an 11-day intensified training period. Twelve recreationally active, healthy males completed the study. Saliva samples were collected before, immediately after and 30 min after both bouts with salivary cortisol and testosterone concentrations assessed. Compared with pre-training blunted exercise-induced salivary cortisol, testosterone and cortisol/testosterone responses to both bouts post-training were observed (P < 0.05 for all). Comparing pre- with post-training the absolute exercise-induced salivary cortisol, testosterone and cortisol/testosterone decreased from 11.1 to 3.1 and 7.0 to 4.4 nmol · L-1 (cortisol), from 407 to 258 and from 473 to 274 pmol · L-1 (testosterone) and from 12 to 4 and 7 to 5 (cortisol/testosterone) for the first and second bouts, respectively (P < 0.05). No differences in the pre- and post-training rating of perceived exertion (RPE) and heart rate (HR) responses during the cycles or times to fatigue were found (P > 0.05). Fatigue and Burnout scores were higher post- compared with pre-training (P < 0.05). These high-intensity exercise bouts can detect altered hormonal responses following intensified training. This test could assess an athlete's current hormonal status, reductions in salivary cortisol and testosterone responses suggestive of increased fatigue
