Decay constants of the charmed vector mesons $D^*$ and $D^*_s$ from QCD
  sum rules

We present a sum-rule calculation of the decay constants of the charmed
vector mesons $D^*$ and $D^*_s$ from the two-point correlator of vector
currents. First, we show that the perturbative expansion in terms of the pole
mass exhibits no sign of convergence whereas the reorganization of this
expansion in terms of the $\overline{\rm MS}$ mass leads to a distinct
hierarchy. Second, making use of the operator product expansion in terms of the
$\overline{\rm MS}$ mass, we determine the decay constants of the $D^*$ and
$D^*_s$ mesons with an emphasis on the uncertainties in these theoretically
predicted quantities related both to the input QCD parameters and to the
limited accuracy of the method of sum rules. Our results are $f_{D^*}=(252.2
\pm 22.3_{\rm OPE}\pm 4_{\rm syst})\; {\rm MeV}$ and $f_{D_s^*}=(305.5 \pm
26.8_{\rm OPE}\pm 5_{\rm syst})\; {\rm MeV}$. For the ratios of the
vector-to-pseudoscalar decay constants we report $f_{D^*}/f_D= 1.221\pm
0.080_{\rm OPE}\pm 0.008_{\rm syst}$ and $f_{D^*_s}/f_{D_s}= 1.241\pm
0.057_{\rm OPE}\pm 0.007_{\rm syst}$.Comment: 9 pages, published versio
Characterizing the folding core of the cyclophilin A - cyclosporin A
  complex I: hydrogen exchange data and rigidity analysis

The determination of a 'folding core' can help to provide insight into the
structure, flexibility, mobility and dynamics, and hence, ultimately, function
of a protein - a central concern of structural biology. Changes in the folding
core upon ligand binding are of particular interest because they may be
relevant to drug-induced functional changes. Cyclophilin A is a
multi-functional ligand-binding protein and a significant drug target. It acts
principally as an enzyme during protein folding, but also as the primary
binding partner for the immunosuppressant drug cyclosporin A (CsA). Here, we
have used hydrogen-deuterium exchange (HDX) NMR spectroscopy to determine the
folding core of the CypA-CsA complex. We also use the rapid computational tool
of rigidity analysis, implemented in FIRST, to determine a theoretical folding
core of the complex. In addition we generate a theoretical folding core for the
unbound protein and compare this with previously published HDX data. The FIRST
method gives a good prediction of the HDX folding core, but we find that it is
not yet sufficiently sensitive to predict the effects of ligand binding on
CypA.Comment: 15 page
Holographic entanglement entropy in metal/superconductor phase
  transition with Born-Infeld electrodynamics

We investigate the holographic entanglement entropy in the
metal/superconductor phase transition for the Born-Infeld electrodynamics with
full backreaction and note that the entropy is a good probe to study the
properties of the phase transition. For the operator $<\mathcal{O}_{-}>$, we
find that the entanglement entropy decreases (or increases) with the increase
of the Born-Infeld parameter $b$ in the metal (or superconducting) phase. For
the operator $<\mathcal{O}_{+}>$, we observe that, with the increase of the
Born-Infeld parameter, the entanglement entropy in the metal phase decreases
monotonously but the entropy in the superconducting phase first increases and
forms a peak at some threshold $b_{T}$, then decreases continuously. Moreover,
the value of $b_{T}$ becomes smaller as the width of the subsystem $A$
decreases.Comment: 12 pages, 5 figures. arXiv admin note: text overlap with

High $p_{T}$ hadron spectra in high-energy heavy-ion collisions

We calculate the hadron spectra in high-energy pp, pA and AA collisions within a pQCD parton model. Analyses of experimental data show that the modification of the spectra in pA and AA as compared to that in $pp$ collisions is consistent with multiple parton scattering scenario and is dictated by the transition from absorptive soft interaction at low p_T to incoherent hard parton scattering at high p_T. This analysis not only sheds new light on the limits to the physics analysis based on thermal fire-ball models but also provides a more quantitative baseline results on which one can study the effects of parton energy loss in the hadron spectra at high p_T
On Consistent Boundary Conditions for c=1 String Theory

We introduce a new parametrisation for the Fermi sea of the $c = 1$ matrix
model. This leads to a simple derivation of the scattering matrix, and a
calculation of boundary corrections in the corresponding $1+1$--dimensional
string theory. The new parametrisation involves relativistic chiral fields,
rather than the non-relativistic fields of the usual formulations. The
calculation of the boundary corrections, following recent work of Polchinski,
allows us to place restrictions on the boundary conditions in the matrix model.
We provide a consistent set of boundary conditions, but believe that they need
to be supplemented by some more subtle relationship between the space-time and
matrix model. Inspired by these boundary conditions, some thoughts on the black
hole in $c=1$ string theory are presented.Comment: 13 pages, 2 postscript figures include
Spectrophotometric analysis of GRB afterglow extinction curves with
  X-shooter

In this work we use gamma-ray burst (GRB) afterglow spectra observed with the
VLT/X-shooter spectrograph to measure rest-frame extinction in GRB
lines-of-sight by modeling the broadband near-infrared (NIR) to X-ray afterglow
spectral energy distributions (SEDs). Our sample consists of nine Swift GRBs,
eight of them belonging to the long-duration and one to the short-duration
class. Dust is modeled using the average extinction curves of the Milky Way and
the two Magellanic Clouds. We derive the rest-frame extinction of the entire
sample, which fall in the range $0 \lesssim {\it A}_{\rm V} \lesssim 1.2$.
Moreover, the SMC extinction curve is the preferred extinction curve template
for the majority of our sample, a result which is in agreement with those
commonly observed in GRB lines-of-sights. In one analysed case (GRB 120119A),
the common extinction curve templates fail to reproduce the observed
extinction. To illustrate the advantage of using the high-quality X-shooter
afterglow SEDs over the photometric SEDs, we repeat the modeling using the
broadband SEDs with the NIR-to-UV photometric measurements instead of the
spectra. The main result is that the spectroscopic data, thanks to a
combination of excellent resolution and coverage of the blue part of the SED,
are more successful in constraining the extinction curves and therefore the
dust properties in GRB hosts with respect to photometric measurements. In all
cases but one the extinction curve of one template is preferred over the
others. We show that the modeled values of the extinction and the spectral
slope, obtained through spectroscopic and photometric SED analysis, can differ
significantly for individual events. Finally we stress that, regardless of the
resolution of the optical-to-NIR data, the SED modeling gives reliable results
only when the fit is performed on a SED covering a broader spectral region.Comment: 17 pages, 7 figures, 4 tables, accepted for publication in Astronomy

In a special run with high-Î²{star operator}beam optics, an integrated luminosity of 80 Î¼b-1was accumulated in order to measure the differential elastic cross section as a function of the Mandelstam momentum transfer variable t. The measurement is performed with the ALFA sub-detector of ATLAS. Using a fit to the differential elastic cross section in the |t| range from 0.01GeV2to 0.1GeV2to extrapolate to |t|â\u86\u920, the total cross section, Ï\u83tot(ppâ\u86\u92X), is measured via the optical theorem to be:Ï\u83tot(ppâ\u86\u92X)=95.35Â±0.38(stat.)Â±1.25(exp.)Â±0.37(extr.)mb, where the first error is statistical, the second accounts for all experimental systematic uncertainties and the last is related to uncertainties in the extrapolation to |t|â\u86\u920. In addition, the slope of the elastic cross section at small |t| is determined to be B=19.73Â±0.14(stat.)Â±0.26(syst.)GeV-2
Static pure Lovelock black hole solutions with horizon topology S (n) × S (n)

It is well known that vacuum equation of arbitrary Lovelock order for static spacetime ultimately reduces to a single algebraic equation, we show that the same continues to hold true for pure Lovelock gravity of arbitrary order N for topology S (n) × S (n) . We thus obtain pure Lovelock static black hole solutions with two sphere topology for any order N , and in particular we study in full detail the third and fourth order Lovelock black holes. It is remarkable that thermodynamical stability of black hole discerns between odd and even N , and consequently between negative and positive Λ and it favors the former while rejecting the latter
Vernacular rights cultures and the 'Right to Have Rights'

We use a case study of the Landless Workers Movement (MST) in Brazil and the Via Campesina network of which they are part to develop the concept of ‘vernacular rights cultures’. Vernacular rights cultures calls attention to the way in which demands for the right to have rights call on particular cultures, histories and political contexts in a manner that can transform the rights inscribed in constitutions and political imaginaries. What Ranciere (1999) and Balibar (2002) call the democratisation of democracy, we therefore argue, does not just involve a logic of equality and inclusion through which dispossessed groups demand already existing rights. Rather, it also occurs as mobilisations alter the means through which rights are delivered and transform the content and meaning of the rights demanded

The dataset, corresponding to 85 nb−1, was recorded with the CMS experiment at the LHC using a low-threshold single-muon trigger. Events are selected by the presence of a muon with transverse momentum puT > 6 GeV with respect to the beam direction and pseudorapidity |η μ | < 2.1. The transverse momentum of the muon with respect to the closest jet discriminates events containing b hadrons from background.

Long-range and short-range dihadron angular correlations in central PbPb collisions at psNN = 2:76 TeV

Attribution Noncommercial License.-- CMS Collaboration: et al.First measurements of dihadron correlationsfor charged particles are presented for central PbPb collisions at a nucleon-nucleon center-of-mass energy of 2.76TeV over a broad range in relative pseudorapidity (∆η) and the full range of relative azimuthal angle (∆ϕ). The data were collected with the CMS detector, at the LHC. A broadening of the away-side (∆ϕ ≈ π) azimuthal correlation is observed at all ∆η, as compared to the measurements in pp collisions. Furthermore, long-range dihadron correlations in ∆η are observed for particles with similar ϕ values. This phenomenon, also known as the “ridge”, persists up to at least |∆η| = 4. For particles with transverse momenta (p T) of2-4 GeV/c, the ridge is found to be most prominent when these particles are correlated with particles of p T = 2-6 GeV/c, and to be much reduced when paired with particles of p T = 10-12 GeV/c.Acknowledge support from: FMSR (Austria); FNRS\ud

A simulation-based decision support tool for informing the management of patients with Parkinson’s disease

We describe a decision support toolkit that was developed with the aim of assisting those responsible with the management and treatment of Parkinson’s disease (PD) in the UK. Having created a baseline model and established its face validity, the toolkit captures the complexity of PD services at a sufficient level and operates within a user friendly environment, that is, an interface was built to allow users to specify their own local PD service and input their own estimates or data of service demands and capacities. The main strength of this decision support tool is the adoption of a team approach to studying the system, involving six PD specialist nurses across the country, ensuring that variety of views and suggestions are taken as well as systems modelling and simulations. The tool enables key decision makers to estimate the likely impact of changes, such as increased use of community services on activity, cost, staffing levels, skill-mix, and utilisation of resources

Simulations of the 2004 lava flow at etna volcano by the magflow cellular automata model

Lava flows represent a challenge for physically based modeling, since the mechanical
properties of lava change over time. This change is ruled by a temperature field, which needs
to be modeled. MAGFLOW Cellular Automata (CA) model was developed for physically
based simulations of lava flows in near real-time. We introduced an algorithm based on the
Monte Carlo approach to solve the anisotropic problem. As transition rule of CA, a steady
state solution of Navier-Stokes equations was adopted in the case of isothermal laminar
pressure-driven Bingham fluid. For the cooling mechanism, we consider the radiative heat
loss only from the surface of the flow, and the change of the temperature due to mixture of
lavas between cells with different temperatures. The model was applied to reproduce a real
lava flow occurred during the 2004-2005 Etna eruption. The simulations were computed
using three different empirical relationships between viscosity and temperature
The impact of trench defects in InGaN/GaN light emitting diodes and implications for the “green gap” problem

The impact of trench defects in blue InGaN/GaN light emitting diodes (LEDs) has been investigated. Two mechanisms responsible for the structural degradation of the multiple quantum well (MQW) active region were identified. It was found that during the growth of the p-type GaN capping layer, loss of part of the active region enclosed within a trench defect occurred, affecting the top-most QWs in the MQW stack. Indium platelets and voids were also found to form preferentially at the bottom of the MQW stack. The presence of high densities of trench defects in the LEDs was found to relate to a significant reduction in photoluminescence and electroluminescence emission efficiency, for a range of excitation power densities and drive currents. This reduction in emission efficiency was attributed to an increase in the density of non-radiative recombination centres within the MQW stack, believed to be associated with the stacking mismatch boundaries which form part of the sub-surface structure of the trench defects. Investigation of the surface of green-emitting QW structures found a two decade increase in the density of trench defects, compared to its blue-emitting counterpart, suggesting the efficiency of green-emitting LEDs may be strongly affected by the presence of these defects. Our results are therefore consistent with a model that the “green gap” problem might relate to localized strain relaxation occurring through defects.This is the accepted manuscript version.

Towards a fully stringy computation of Yukawa couplings on non
  factorized tori and non abelian twist correlators (I): the classical solution
  and action

We consider the simplest possible setting of non abelian twist fields which
corresponds to $SU(2)$ monodromies. We first review the theory of
hypergeometric function and of the solutions of the most general Fuchsian
second order equation with three singularities. Then we solve the problem of
writing the general solution with prescribed $U(2)$ monodromies. We use this
result to compute the classical string solution corresponding to three $D2$
branes in $R^4$. Despite the fact the configuration is supersymmetric the
classical string solution is not holomorphic. Using the equation of motion and
not the KLT approach we give a very simple expression for the classical action
of the string. We find that the classical action is not proportional to the
area of the triangle determined by the branes intersection points since the
solution is not holomorphic. Phenomenologically this means that the Yukawa
couplings for these supersymmetric configurations on non factorized tori are
suppressed with respect to the factorized case.Comment: 51 pages, 16 figure
On the asymptotic limit of the three dimensional Vlasov-Poisson system
  for large magnetic field : formal derivation

This paper establishes the long time asymptotic limit of the three
dimensional Vlasov-Poisson equation with strong external magnetic field. The
guiding center approximation is investigated in the three dimensional case with
a non-constant magnetic field. In the long time asymptotic limit, the motion
can be split in two parts : one stationary flow along the lines of the magnetic
field and the guiding center motion in the orthogonal plane of the magnetic
field where classical drift velocities are recovered. We discuss in particular
the effect of nonconstant external magnetic fields.Comment: arXiv admin note: text overlap with arXiv:0905.240
Optimising Charged Higgs Boson Searches at the Large Hadron Collider
  Across $b\bar b W^\pm$ Final States

In the light of the most recent data from Higgs boson searches and analyses,
we re-assess the scope of the Large Hadron Collider in accessing heavy charged
Higgs boson signals in $b\bar b W^\pm$ final states, wherein the contributing
channels can be $H^+\to t\bar b$, $hW^\pm, HW^\pm$ and $AW^\pm$. We consider a
2-Higgs Doublet Model Type-II and we assume as production mode $bg\to tH^-$ +
c.c., the dominant one over the range $M_{H^\pm}\ge 480$ GeV, as dictated by
$b\to s\gamma$ constraints. Prospects of detection are found to be significant
for various Run 2 energy and luminosity options.Comment: 15 pages, 10 figures, 3 table
Forced Fluid Dynamics from Blackfolds in General Supergravity
  Backgrounds

We present a general treatment of the leading order dynamics of the
collective modes of charged dilatonic $p$-brane solutions of (super)gravity
theories in arbitrary backgrounds. To this end we employ the general strategy
of the blackfold approach which is based on a long-wavelength derivative
expansion around an exact or approximate solution of the (super)gravity
equations of motion. The resulting collective mode equations are formulated as
forced hydrodynamic equations on dynamically embedded hypersurfaces. We derive
them in full generality (including all possible asymptotic fluxes and dilaton
profiles) in a far-zone analysis of the (super)gravity equations and in
representative examples in a near-zone analysis. An independent treatment based
on the study of external couplings in hydrostatic partition functions is also
presented. Special emphasis is given to the forced collective mode equations
that arise in type IIA/B and eleven-dimensional supergravities, where besides
the standard Lorentz force couplings our analysis reveals additional couplings
to the background, including terms that arise from Chern-Simons interactions.
We also present a general overview of the blackfold approach and some of the
key conceptual issues that arise when applied to arbitrary backgrounds.Comment: v2: 47pp, typos corrected, presentation improved, matches published
