Singlet-to-triplet ratio in the deuteron breakup reaction $pd\to pnp$ at
  585 MeV

Available experimental data on the exclusive $pd\to pnp$ reaction at 585 MeV
show a narrow peak in the proton-neutron final-state interaction region. It was
supposed previously, on the basis of a phenomenological analysis of the shape
of this peak, that the final spin-singlet $pn$ state provided about one third
of the observed cross section. By comparing the absolute value of the measured
cross section with that of $pd$ elastic scattering using the F\"aldt-Wilkin
extrapolation theorem, it is shown here that the $pd\to pnp$ data can be
explained mainly by the spin-triplet final state with a singlet admixture of a
few percent. The smallness of the singlet contribution is compatible with
existing $pN\to pN\pi$ data and the one-pion exchange mechanism of the $pd\to
pnp$ reaction.Comment: 10 pages, Latex, 2 Postscript figure
Interactions and dynamics in Li + Li_2 ultracold collisions

A potential energy surface for the lowest quartet electronic state of lithium
trimer is developed and used to study spin-polarized Li + Li_2 collisions at
ultralow kinetic energies. The potential energy surface allows barrierless atom
exchange reactions. Elastic and inelastic cross sections are calculated for
collisions involving a variety of rovibrational states of Li_2. Inelastic
collisions are responsible for trap loss in molecule production experiments.
Isotope effects and the sensitivity of the results to details of the potential
energy surface are investigated. It is found that for vibrationally excited
states the cross sections are only quite weakly dependent on details of the
potential energy surface.Comment: 21 pages, 27 figures. Version 2 is final version as accepted for

Measurement of the branching fractions of $D_{s}^{+}\rightarrow \eta'X$
  and $D_{s}^{+}\rightarrow \eta'\rho^{+}$ in $e^+e^-\to D^+_{s}D^-_{s}$

We study $D_{s}^{+}$ decays to final states involving the $\eta'$ with a
482$\,$pb$^{-1}$ data sample collected at $\sqrt{s}$ = 4.009$\,$GeV with the
\mbox{BESIII} detector at the BEPCII collider. We measure the branching
fractions $\mathcal{B}(D^+_{s}\rightarrow \eta'X)$ = (8.8$\pm$1.8$\pm$0.5)$\%$
and $\mathcal{B}(D_{s}^{+}\rightarrow \eta'\rho^{+})$ = ($5.8\pm1.4\pm0.4$)$\%$
where the first uncertainty is statistical and the second is systematic. In
addition, we estimate an upper limit on the non-resonant branching ratio
$\mathcal{B}(D_{s}^{+}\rightarrow \eta'\pi^+\pi^0)<5.1\%$ at the 90$\%$
confidence level. Our results are consistent with CLEO's recent measurements
and help to resolve the disagreement between the theoretical prediction and
CLEO's previous measurement of $\mathcal{B}(D_{s}^{+}\rightarrow
\eta'\rho^{+})$
Search for long-lived, multi-charged particles in pp collisions at sqrts=7 TeV using the ATLAS detector

A search for highly ionising, penetrating particles with electric charges from |q| = 2e to 6e is performed using the ATLAS detector at the CERN Large Hadron Collider. Proton-proton collision data taken at sqrt(s)=7 TeV during the 2011 running period, corresponding to an integrated luminosity of 4.4 fb^-1, are analysed. No signal candidates are observed, and 95% confidence level cross-section upper limits are interpreted as mass-exclusion lower limits for a simplified Drell--Yan production model. In this model, masses are excluded from 50 GeV up to 430, 480, 490, 470 and 420 GeV for charges 2e, 3e, 4e, 5e and 6e, respectively
Search for pair-produced resonances decaying to jet pairs in proton-proton collisions at s=8 TeV

Results are reported of a general search for pair production of heavy resonances decaying to pairs of hadronic jets in events with at least four jets. The study is based on up to 19.4 fb−1 of integrated luminosity from proton–proton collisions at a center-of-mass energy of 8 TeV, recorded with the CMS detector at the LHC. Limits are determined on the production of scalar top quarks (top squarks) in the framework of R-parity violating supersymmetry and on the production of color-octet vector bosons (colorons). First limits at the LHC are placed on top squark production for two scenarios. The first assumes decay to a bottom quark and a light-flavor quark and is excluded for masses between 200 and 385 GeV, and the second assumes decay to a pair of light-flavor quarks and is excluded for masses between 200 and 350 GeV at 95% confidence level. Previous limits on colorons decaying to light-flavor quarks are extended to exclude masses from 200 to 835 GeV
On the κ -Dirac oscillator revisited

This Letter is based on the κ -Dirac equation, derived from the κ -Poincaré–Hopf algebra. It is shown that the κ -Dirac equation preserves parity while breaks charge conjugation and time reversal symmetries. Introducing the Dirac oscillator prescription, <math altimg="si1.gif" xmlns="http://www.w3.org/1998/Math/MathML"><mi mathvariant="bold">p</mi><mo stretchy="false">→</mo><mi mathvariant="bold">p</mi><mo>−</mo><mi>i</mi><mi>m</mi><mi>ω</mi><mi>β</mi><mi mathvariant="bold">r</mi></math> , in the κ -Dirac equation, one obtains the κ -Dirac oscillator. Using a decomposition in terms of spin angular functions, one achieves the deformed radial equations, with the associated deformed energy eigenvalues and eigenfunctions. The deformation parameter breaks the infinite degeneracy of the Dirac oscillator. In the case where <math altimg="si2.gif" xmlns="http://www.w3.org/1998/Math/MathML"><mi>ε</mi><mo>=</mo><mn>0</mn></math> , one recovers the energy eigenvalues and eigenfunctions of the Dirac oscillator
Minimal R+R2 supergravity models of inflation coupled to matter

The supersymmetric extension of “Starobinsky” R+αR2 models of inflation is particularly simple in the “new minimal” formalism of supergravity, where the inflaton has no scalar superpartners. This paper is devoted to matter couplings in such supergravity models. We show how in the new minimal formalism matter coupling presents certain features absent in other formalisms. In particular, for the large class of matter couplings considered in this paper, matter must possess an R-symmetry, which is gauged by the vector field which becomes dynamical in the “new minimal” completion of the R+αR2 theory. Thus, in the dual formulation of the theory, where the gauge vector is part of a massive vector multiplet, the inflaton is the superpartner of the massive vector of a nonlinearly realized R-symmetry. The F-term potential of this theory is of no-scale type, while the inflaton potential is given by the D-term of the gauged R-symmetry. The absolute minimum of the potential is always exactly supersymmetric, so in this class of models if realistic vacua exist, they must be always metastable. We also briefly comment on possible generalizations of the examples discussed here and we exhibit some features of higher-curvature supergravity coupled to matter in the “old minimal” formalism
QCD NLO and EW NLO corrections to tt¯H production with top quark decays at hadron collider

Higgs boson production associated with a top quark pair is an important process in studying the nature of the newly discovered Higgs boson at the LHC. In this letter, we report on our calculations including the next-to-leading order (NLO) QCD and NLO electroweak corrections to the pp→tt¯H process in the standard model. We present the integrated cross sections at the 14 TeV LHC and even at the future proton–proton colliders with s=33 and 100TeV . Our calculation includes the top quark subsequent decays by adopting the narrow width approximation. The kinematic distributions of Higgs boson and top quark decay products at the LHC are provided. We find that the O(αs2αew2) corrections are quantitatively comparable with the O(αs3αew) corrections in some kinematic region
SUSY properties of warped AdS 3

We examine supersymmetric properties of null-warped AdS 3 , or alternatively Schrödinger geometries, dual to putative warped CFTs in two dimensions. We classify super Schrödinger subalgebras of the superalgebra psu(1, 1|2) ⊕ psu(1, 1|2), corresponding to the superconformal algebra of the AdS 3 × S 3 geometry. We comment on geometric realisations and provide a string theory description with enhanced supersymmetry in terms of intersecting D3-branes. For type IIB supergravity solutions based on T 1,1 , we consider the relationship between five-dimensional Schrödinger solutions and their three-dimensional null-warped counterparts, corresponding to R symmetry twists. Finally, we study a family of null-warped AdS 3 solutions in a setting where there is an ambiguity over the R symmetry and confirm that, for examples admitting a Kaluza-Klein (KK) reduction to three dimensions, the minimisation of a real superpotential of the three-dimensional gauged supergravity captures the central charge and R symmetry
N =2 SO(4) 7D gauged supergravity with topological mass term from 11 dimensions

We construct a consistent reduction ansatz of eleven-dimensional supergravity to N =2 SO(4) seven-dimensional gauged supergravity with topological mass term for the three-form field. The ansatz is obtained from a truncation of the S 4 reduction giving rise to the maximal N =4 SO(5) gauged supergravity. Therefore, the consistency is guaranteed by the consistency of the S 4 reduction. Unlike the gauged supergravity without topological mass having a half-supersymmetric domain wall vacuum, the resulting 7D gauged supergravity theory admits a maximally supersymmetric AdS 7 critical point. This corresponds to N = (1 , 0) superconformal field theory in six dimensions. We also study RG flows from this N = (1 , 0) SCFT to non-conformal N = (1 , 0) Super Yang-Mills theories in the seven-dimensional framework and use the reduction ansatz to uplift this RG flow to eleven dimensions
Exact solution of the 2 d dimer model: Corner free energy, correlation functions and combinatorics

In this work, some classical results of the pfaffian theory of the dimer model based on the work of Kasteleyn, Fisher and Temperley are introduced in a fermionic framework. Then we shall detail the bosonic formulation of the model via the so-called height mapping and the nature of boundary conditions is unravelled. The complete and detailed fermionic solution of the dimer model on the square lattice with an arbitrary number of monomers is presented, and finite size effect analysis is performed to study surface and corner effects, leading to the extrapolation of the central charge of the model. The solution allows for exact calculations of monomer and dimer correlation functions in the discrete level and the scaling behavior can be inferred in order to find the set of scaling dimensions and compare to the bosonic theory which predicts particular features concerning corner behaviors. Finally, some combinatorial and numerical properties of partition functions with boundary monomers are discussed, proved and checked with enumeration algorithms
The Variscan gabbros from the Spanish Central System: A case for crustal recycling in the sub-continental lithospheric mantle?

15 páginas, 12 figuras, 4 tablas.-- El Pdf del artículo es la versión post-print.The gabbroic intrusions that crop out along the Spanish Central System (SCS) are geochemically heterogeneous, including primitive and evolved rocks. Differentiation is mainly related to fractionation of Cr-spinel and olivine, but mixing with coeval granitic magmas or crustal assimilation may have also played a role in the evolution of the most differentiated rocks. The most primitive uncontaminated gabbros show arc-like trace element chondrite and primitive-mantle normalised patterns, characterised by large ion lithophile elements (LILE)-light rare earth elements (LREE) enrichment, Sr and Pb positive and Nb–Ta–Ti negative anomalies. However, paleogeographic constraints suggest that the SCS was located far from subduction zones, so these geochemical signatures could be better explained by a recycling of continental crustal components within the mantle. The most primitive SCS gabbros expand the Sr–Nd isotopic compositional range of the Variscan basic magmatism in the Central Iberian Zone to more depleted values. This reflects a heterogeneous sub-continental lithospheric mantle under central Spain ranging from a depleted mantle (εNd = + 3.1, 87Sr/86Sr = 0.704) towards an isotopically enriched component (εNd = − 1.6, 87Sr/86Sr = 0.706). Geochemical modelling suggests that mantle enrichment could be explained by minor lower crustal metapelitic granulite contamination (~ 2%). Additionally, the Sr–Nd–Pb isotopic ratios of the most primitive gabbros match the composition of the European subcontinental lithospheric mantle recorded in ultramafic xenoliths from western and central Europe.This work is included in the objectives of,\ud

Measurement of dijet cross-sections in pp collisions at 7 TeV centre-of-mass energy using the ATLAS detector

Double-differential dijet cross-sections measured in pp collisions at the LHC with a 7 TeV centre-of-mass energy are presented as functions of dijet mass and half the rapidity separation of the two highest-p(T) jets. These measurements are obtained using data corresponding to an integrated luminosity of 4.5 fb(-1), recorded by the ATLAS detector in 2011. The data are corrected for detector effects so that cross-sections are presented at the particle level. Cross-sections are measured up to 5 TeV dijet mass using jets reconstructed with the anti-k(t) algorithm for values of the jet radius parameter of 0.4 and 0.6. The cross-sections are compared with next-to-leading-order perturbative QCD calculations by NLOJet++ corrected to account for non-perturbative effects. Comparisons with POWHEG predictions, using a next-to-leading-order matrix element calculation interfaced to a parton-shower Monte Carlo simulation, are also shown. Electroweak effects are accounted for in both cases. The quantitative comparison of data and theoretical predictions obtained using various parameterizations of the parton distribution functions is performed using a frequentist method. In general, good agreement with data is observed for the NLOJet++ theoretical predictions when using the CT10, NNPDF2.1 and MSTW 2008 PDF sets. Disagreement is observed when using the ABM11 and HERAPDF1.5 PDF sets for some ranges of dijet mass and half the rapidity separation. An example setting a lower limit on the compositeness scale for a model of contact interactions is presented, showing that the unfolded results can be used to constrain contributions to dijet production beyond that predicted by the Standard Model.<p>ATLAS Collaboration, for complete list of authors see http://dx.doi.org/10.1007/JHEP05(2014)059</p
Web Videos: concerns about accessibility based on User Centered Design

Recently, the production and availability of multimedia Web content, as videos, have increased. In this scenario it is important to consider accessibility requirements so that any user can whelm the barriers to access content regardless of the limitations imposed by either deficiency or some temporary restriction. One of the main barriers found in the current players is the restriction to make videos accessible on the Web and little research on how to overcome those limitations has been conducted. This paper describes the three phases of User Centered Design, in which an evaluation with real users of an accessible video player is conducted. A video player, called Facilitas, is proposed in order to provide the rationale of how some of those barriers or limitations could be overcome. Its controls are new and different from the ones in other players. We have observed that by reducing accessibility barriers, the design process leads to an improved product in terms of usability. A user testing is described to explain which controls users frequently use to complete a task.CAPES (PEC-PG)5th International Conference on Software Development and Technologies for Enhancing Accessibility and Fighting Info-exclusion (DSAI 2013). \ud

Structure-activity relationships of hypervalent organochalcogenanes as inhibitors of cysteine cathepsins V and S

A new series of organotelluranes were synthesized and investigated, and the structure-activity relationships in cysteine proteases inhibition were determinated. It was possible to identify the relevance of structural components linked to the reactivity of these compounds as inhibitors. for example, dibromo-organotelluranes showed to be more reactive than dichloro-organotelluranes towards cysteine cathepsins V and S. Besides, no remarkable enantio-selectivity was verified. in general the achiral organotelluranes were more reactive than the chiral congeners against cysteine cathepsins V and S. A reactivity order for organochalcogenanes and cysteine cathepsins was proposed after the comparison of the inhibitory potencies of organotelluranes with the related organoselenanes.

Generation of a replication-competent chimeric simian-human immunodeficiency virus carrying env from subtype C clinical isolate through intracellular homologous recombination.

A new simian-human immunodeficiency virus (SHIV), carrying env from an uncloned HIV-1 subtype C clinical isolate (97ZA012), was generated through intracellular homologous recombination, a DNA repair mechanism of the host cell. PCR fragments amplified from an existing SHIV plasmid (a 7-kb fragment from the 5' end and a 1.5-kb fragment from the 3' end) and a 4-kb fragment amplified from 97ZA012 cDNA containing env were co-transfected to human lymphoid cells. The resulting recombinant was subjected to serial passage in rhesus peripheral blood mononuclear cells (RhPBMCs). The resulting SHIV 97ZA012 was replication competent in RhPBMCs and monkey alveolar macrophages, and possessed CCR5 preference as an entry co-receptor. Experimental infection of rhesus macaques with SHIV 97ZA012 caused high titers of plasma viremia and a transient but profound depletion of CD4(+) T lymphocytes in the lung. Animal-to-animal passage was shown to be a promising measure for further adaptation of the virus in monkeys

The Italian strong motion data base: design, data input and web distribution

A new Italian strong-motion data base was created during a joint project between Istituto Nazionale di Geofisica e Vulcanologia (INGV, Italian Institute for Geophysics and Vulcanology) and Dipartimento della Protezione Civile (DPC, Italian civil protection).  
The aim of the project was the collection, homogenization and distribution of strong motion data acquired in the time span 1972-2004 in Italy by different institutions, namely Ente Nazionale per l’Energia Elettrica (ENEL, Italian electricity company), Ente per le Nuove tecnologie, l’Energia e l’Ambiente (ENEA, Italian energy and environment organization) and DPC with different purposes, such as permanent strong motion monitoring and temporary monitoring during seismic sequences or before permanent installation. 
The data base contains 2182 three component waveforms generated by 1004 earthquakes with a maximum moment magnitude of 6.9 (1980 Irpinia earthquake) and can be accessed on-line at the site http://itaca.mi.ingv.it, where a wide range of search tools enables the user to interactively retrieve events, recording stations and waveforms with particular characteristics, whose parameters can be specified, as needed, through user friendly interfaces. A range of display options allows users to view data in different contexts, extract and download time series and spectral data.
This article describes the data base structure and the working steps which led to the completion of the project
Evidence for surface rupture associated with the Mw 6.3 L’Aquila earthquake sequence of April 2009 (central Italy)

An earthquake of Mw=6.3 struck L’Aquila town (central Italy) on April 6, 2009 rupturing an
approximately 18 km long SW-dipping normal fault. The aftershock area extended for a length of more than 35 km and included major aftershocks on April 7 and 9, and thousands of minor events.
Surface faulting occurred along the SW-dipping Paganica fault with a continuous extent of ~2.5 km.
Ruptures consist of open cracks and vertical dislocations or warps (0.1 maximum throw) with an orientation of N130°-N140°. Small triggered slip and shaking effects also took place along nearby synthetic and antithetic normal faults. The observed limited extent, and small surface displacement, of the Paganica ruptures with respect to the height of the fault scarps and vertical throws of paleoearthquakes along faults in the area, puts the faulting associated with the L’Aquila earthquake in perspective with respect to the maximum expected magnitude, and the regional seismic hazard
Diversity of 26-locus Y-STR haplotypes in a Nepalese population sample: isolation and drift in the Himalayas.

26 Y-chromosomal short tandem repeat (STR) loci were amplified in a sample of 769 unrelated males from Nepal, using two multiplex polymerase chain reaction (PCR) assays. The 26 loci gave a discriminating power of 0.997, with 59% unique haplotypes, and the highest frequency haplotype occurring 12 times. We identified novel alleles at four loci, microvariants at a further two, and nine examples of amelogenin-Y deletions (1.2%). Comparison with a\ud
similarly sized Bhutanese sample typed with the same markers suggested histories of isolation and drift, with drift having a greater effect in Bhutan. Extended (11-locus) haplotypes for the Nepalese samples have been submitted to the Y-STR Haplotype Reference Database
