Effects of dark energy on P-V criticality of charged AdS black holes

In this Letter, we investigate the effects of dark energy on $P-V$
criticality of charged AdS black holes by considering the case of the RN-AdS
black holes surrounded by quintessence. By treating the cosmological constant
as thermodynamic pressure, we study its thermodynamics in the extended phase
space. It is shown that quintessence dark energy does not affect the existence
of small/large black hole phase transition. For the case $\omega_q=-2/3$ we
derive analytic expressions of critical physical quantities, while for cases
$\omega_q\neq-2/3$ we appeal to numerical method for help. It is shown that
quintessence dark energy affects the critical physical quantities near the
critical point. Critical exponents are also calculated. They are exactly the
same as those obtained before for arbitrary other AdS black holes, which
implies that quintessence dark energy does not change the critical exponents.Comment: 13 pages, 2 figure
Unbroken $SU(2)$ at a 100 TeV collider

A future 100 TeV pp collider will explore energies much higher than the scale
of electroweak (EW) symmetry breaking. In this paper we study some of the
phenomenological consequences of this fact, concentrating on enhanced
bremsstrahlung of EW gauge bosons. We survey a handful of possible new physics
experimental searches one can pursue at a 100 TeV collider using this
phenomenon. The most dramatic effect is the non-negligible radiation of EW
gauge bosons from neutrinos, making them partly visible objects. The presence
of collinear EW radiation allows for the full reconstruction of neutrinos under
certain circumstances. We also show that the presence of EW radiation allows
one to distinguish the $SU(2)$ quantum numbers of various new physics
particles. We consider examples of two completely different new physics
paradigms, additional gauge groups and SUSY, where the bremsstrahlung radiation
of $W$ and $Z$ from $W'$s, $Z'$s or stops allows one to determine the couplings
and the mixing angles of the new particles (respectively). Finally, we show how
the emission of $W$s and $Z$s from high $p_T$ Higgs bosons can be used to test
the couplings of new physics to the Higgs boson.Comment: 27 pages, 10 figure
Lifshitz flows in IIB and dual field theories

We construct solutions describing flows between AdS and Lifshitz spacetimes
in IIB supergravity. We find that flows from AdS$_5$ can approach either
AdS$_3$ or Lifshitz$_3$ in the IR depending on the values of the deformation
from AdS$_5$. Surprisingly, the choice between AdS and Lifshitz IR depends only
on the value of the deformation, not on its character; the breaking of the
Lorentz symmetry in the flows with Lifshitz IR is spontaneous. We find that the
values of the deformation which lead to flows to Lifshitz make the UV field
theory dual to the AdS$_5$ geometry unstable, so that these flows do not offer
an approach to defining the field theory dual to the Lifshitz spacetime.Comment: 25 pages, 7 figures, references adde
The surface signature of the tidal dissipation of the core in a
  two-layer planet

Tidal dissipation, which is directly linked to internal structure, is one of
the key physical mechanisms that drive systems evolution and govern their
architecture. A robust evaluation of its amplitude is thus needed to predict
evolution time for spins and orbits and their final states. The purpose of this
paper is to refine recent model of the anelastic tidal dissipation in the
central dense region of giant planets, commonly assumed to retain a large
amount of heavy elements, which constitute an important source of dissipation.
The previous paper evaluated the impact of the presence of the static fluid
envelope on the tidal deformation of the core and on the associated anelastic
tidal dissipation, through the tidal quality factor Qc. We examine here its
impact on the corresponding effective anelastic tidal dissipation, through the
effective tidal quality factor Qp. We show that the strength of this mechanism
mainly depends on mass concentration. In the case of Jupiter- and Saturn-like
planets, it can increase their effective tidal dissipation by, around, a factor
2.4 and 2 respectively. In particular, the range of the rheologies compatible
with the observations is enlarged compared to the results issued from previous
formulations. We derive here an improved expression of the tidal effective
factor Qp in terms of the tidal dissipation factor of the core Qc, without
assuming the commonly used assumptions. When applied to giant planets, the
formulation obtained here allows a better match between the an elastic core's
tidal dissipation of a two-layer model and the observations.Comment: 5 pages, 2 figures, Accepted for publication in Astronomy &

The BV-algebra structure of W$_{3}$ cohomology

We summarize some recent results obtained in collaboration with J. McCarthy on the spectrum of physical states in W_3 gravity coupled to c=2 matter. We show that the space of physical states, defined as a semi-infinite (or BRST) cohomology of the W_3 algebra, carries the structure of a BV-algebra. This BV-algebra has a quotient which is isomorphic to the BV-algebra of polyvector fields on the base affine space of SL(3,C). Details have appeared elsewhere.

Search for Low Scale Gravity Effects in $e^+ e^-$ Collisions at LEP

Recent theories propose that quantum gravity effects may be observable at LEP energies via gravitons that couple to Standard Model particles and propagate into extra spatial dimensions. The associated production of a graviton and a photon is searched for as well as the effects of virtual graviton exchange in the processes: $\rm e^+e^-\rightarrow \gamma\gamma$, ZZ, $\rm W^+ W^-$, $\mu^+\mu^-$, $\tau^+\tau^-$, $\rm q \bar{q}$ and $\rm e^+e^-$. No evidence for this new interaction is found in the data sample collected by the L3 detector at LEP at centre--of--mass energies up to 183\,GeV. Limits close to 1\,TeV on the scale of this new scenario of quantum gravity are set
Noncommutative SU(N) theories, the axial anomaly, Fujikawa's method and
  the Atiyah-Singer index

Fujikawa's method is employed to compute at first order in the noncommutative
parameter the $U(1)_A$ anomaly for noncommutative SU(N). We consider the most
general Seiberg-Witten map which commutes with hermiticity and complex
conjugation and a noncommutative matrix parameter, $\theta^{\mu\nu}$, which is
of ``magnetic'' type. Our results for SU(N) can be readily generalized to cover
the case of general nonsemisimple gauge groups when the symmetric
Seiberg-Witten map is used. Connection with the Atiyah-Singer index theorem is
also made.Comment: 11 pages, no figure
Renormalization of the f0(980) and a0(980) scalar resonances in a
  nuclear medium

The meson meson interaction in the scalar sector in the presence of a nuclear
medium is studied with particular attention to the change of the properties of
the f0(980) and a0(980) resonances. By using a chiral unitary approach which
generates the f0 and a0 resonances and reproduces their free properties, we
find that the position of the resonances in the medium is barely changed but
their widths are considerably broadened. New many body corrections generating
from higher orders in the chiral Lagrangian plus the contribution from N*h
excitations, not considered before in connection with the pion-pion interaction
in the nuclear medium, are also investigated.Comment: 24 pages, 15 figure
MAPKAP kinase 2 (MK2)-dependent and independent models of blister formation in pemphigus vulgaris

Pemphigus vulgaris (PV) is an autoimmune blistering disease characterized by autoantibodies to the keratinocyte adhesion protein desmoglein (Dsg) 3. Previous studies suggest that PV pathogenesis involves p38 mitogen activated protein kinase-dependent and -independent pathways. However, p38 is a difficult protein to study and therapeutically target because it has four isoforms and multiple downstream effectors. In the current study, we identify MAPKAP kinase 2 (MK2) as a downstream effector of p38 signaling in PV and describe MK2-dependent and -independent mechanisms of blister formation using passive transfer of human anti-Dsg IgG4 mAbs to neonatal mice. In human keratinocytes, PV mAbs activate MK2 in a dose-dependent manner. MK2 is also activated in human pemphigus skin blisters, causing translocation of MK2 from the nucleus to the cytosol. Small molecule inhibition of MK2 and silencing of MK2 expression block PV mAb-induced Dsg3 endocytosis in human keratinocytes. Additionally, small molecule inhibition and genetic deletion of p38α and MK2 inhibit spontaneous, but not induced, suprabasal blisters by PV mAbs in mouse passive transfer models. Collectively, these data suggest that MK2 is a key downstream effector of p38 that can modulate PV autoantibody pathogenicity. MK2 inhibition may be a valuable adjunctive therapy for control of pemphigus blistering
Flammability conditions for ultra-lean hydrogen premixed combustion based on flame-ball analyses

Proceeding of: 10th International Conference on Clean Energy 2010, 15-17 September 2010, Famagusta, North CyprusIt has been reasoned that the structures of strongly cellular flames in very lean mixtures approach an array of flame balls, each burning as if it were isolated, thereby indicating a connection between the critical conditions required for existence of steady flame balls and those necessary for occurrence of self-sustained premixed combustion. This is the starting assumption of the present study, in which structures of near-limit steady sphericosymmetrical
flame balls are investigated with the objective of providing analytic expressions for critical combustion conditions in ultra-lean hydrogen-oxygen mixtures diluted with N2 and water vapor. If attention were restricted to planar premixed flames, then the lean-limit mole fraction of H2 would be found to be roughly ten percent, more than twice the observed flammability limits, thereby emphasizing the relevance of the flame-ball phenomena.
Numerical integrations using detailed models for chemistry and radiation show that a onestep chemical-kinetic reduced mechanism based on steady-state assumptions for all chemical intermediates, together with a simple, optically thin approximation for water-vapor
radiation, can be used to compute near-limit fuel-lean flame balls with excellent accuracy. The previously developed one-step reaction rate includes a crossover temperature that
determines in the first approximation a chemical-kinetic lean limit below which combustion cannot occur, with critical conditions achieved when the diffusion-controlled radiation-free peak temperature, computed with account taken of hydrogen Soret diffusion, is equal to the crossover temperature. First-order corrections are found by activation-energy asymptotics in
a solution that involves a near-field radiation-free zone surrounding a spherical flame sheet, together with a far-field radiation-conduction balance for the temperature profile. Different
scalings are found depending on whether or not the surrounding atmosphere contains water vapor, leading to different analytic expressions for the critical conditions for flame-ball existence, which give results in very good agreement with those obtained by detailed
numerical computations. The one-step chemistry employed in the present work, which involves a non-Arrhenius rate having a cutoff at the crossover temperature, applies with excellent accuracy to the description of lean premixed hydrogen-air combustion, i.e, for
f(0:5 at atmospheric pressure, and could be used for instance in the numerical simulation of the propagation of curved or cellularflames in ultra-lean reactive atmospheres, of interest for
safety analyses related to the storage, transport, and handling of hydrogen.This work was supported by the Comunidad de Madrid

Compactifications of the Klebanov-Witten CFT and new $AdS_3$ backgrounds

In this paper we find various new backgrounds in Type IIB, IIA and M-theory
with an $AdS_3$-factor. The solutions are smooth and preserve small amounts of
SUSY. These new backgrounds are found by application of non-Abelian T-duality
(sometimes combined with T-duality) on the supergravity solution dual to the
Klebanov-Witten CFT compactified to two dimensions. The field theory aspects
encoded by these backgrounds are studied. We give a detailed account of
conserved charges, central charges, entanglement entropy and Wilson loops.
Further, we present a possible field theory interpretation for our backgrounds.Comment: 38 pages plus appendices, 6 figure
The Neural Particle Filter

The robust estimation of dynamically changing features, such as the position
of prey, is one of the hallmarks of perception. On an abstract, algorithmic
level, nonlinear Bayesian filtering, i.e. the estimation of temporally changing
signals based on the history of observations, provides a mathematical framework
for dynamic perception in real time. Since the general, nonlinear filtering
problem is analytically intractable, particle filters are considered among the
most powerful approaches to approximating the solution numerically. Yet, these
algorithms prevalently rely on importance weights, and thus it remains an
unresolved question how the brain could implement such an inference strategy
with a neuronal population. Here, we propose the Neural Particle Filter (NPF),
a weight-less particle filter that can be interpreted as the neuronal dynamics
of a recurrently connected neural network that receives feed-forward input from
sensory neurons and represents the posterior probability distribution in terms
of samples. Specifically, this algorithm bridges the gap between the
computational task of online state estimation and an implementation that allows
networks of neurons in the brain to perform nonlinear Bayesian filtering. The
model captures not only the properties of temporal and multisensory integration
according to Bayesian statistics, but also allows online learning with a
maximum likelihood approach. With an example from multisensory integration, we
demonstrate that the numerical performance of the model is adequate to account
for both filtering and identification problems. Due to the weightless approach,
our algorithm alleviates the 'curse of dimensionality' and thus outperforms
conventional, weighted particle filters in higher dimensions for a limited
number of particles
Search for neutral Higgs bosons of the minimal supersymmetric standard model in pp collisions at sqrts = 8 TeV with the ATLAS detector

A search for the neutral Higgs bosons predicted by the Minimal Supersymmetric Standard Model (MSSM) is reported. The analysis is performed on data from proton-proton collisions at a centre-of-mass energy of 8 TeV collected with the ATLAS detector at the Large Hadron Collider. The samples used for this search were collected in 2012 and correspond to integrated luminosities in the range 19.5-20.3 fb−1. The MSSM Higgs bosons are searched for in the τ τ final state. No significant excess over the expected background is observed, and exclusion limits are derived for the production cross section times branching fraction of a scalar particle as a function of its mass. The results are also interpreted in the MSSM parameter space for various benchmark scenarios
Comparison of the $Z/\gamma^{*}$ + jets to $\gamma$ + jets cross sections in $pp$ collisions at $\sqrt{s}$=8 TeV

A comparison of the differential cross sections for the processes $Z/\gamma^{*}$ + jets and photon ($\gamma$) + jets is presented. The measurements are based on data collected with the CMS detector at $\sqrt{s}$=8 TeV corresponding to an integrated luminosity of 19.7 $fb^{-1}$ inverse femtobarns. The differential cross sections and their ratios are presented as functions of pt. The measurements are also shown as functions of the jet multiplicity. Differential cross sections are obtained as functions of the ratio of the $Z/\gamma^{*}$ pt to the sum of all jet transverse momenta and of the ratio of the $Z/\gamma^{*}$ pt to the leading jet transverse momentum. The data are corrected for detector effects and are compared to simulations based on several QCD calculations
MAGIC observations of the giant radio galaxy M 87 in a low-emission state between 2005 and 2007

We present the results of a long M 87 monitoring campaign in very high energy gamma-rays with the MAGIC-I Cherenkov telescope. We aim to model the persistent non-thermal jet emission by monitoring and characterizing the very high energy gamma-ray emission of M 87 during a low state. A total of 150 h of data were taken between 2005 and 2007 with the single MAGIC-I telescope, out of which 128.6 h survived the data quality selection. We also collected data in the X-ray and Fermi-LAT bands from the literature (partially contemporaneous). No flaring activity was found during the campaign. The source was found to be in a persistent low-emission state, which was at a confidence level of 7 sigma. We present the spectrum between 100 GeV and 2 TeV, which is consistent with a simple power law with a photon index GAMMA = 2.21 ± 0.21 and a flux normalization at 300 GeV of (7.7 +- 1.3) x 10^-8 TeV^-1 s^-1 m^-2. The extrapolation of the MAGIC spectrum into the GeV energy range matches the previously published Fermi-LAT spectrum well, covering a combined energy range of four orders of magnitude with the same spectral index. We model the broad band energy spectrum with a spine layer model, which can satisfactorily describe our data
Measurement of electrons from beauty hadron decays in pp collisions at sqrt(s)=7 TeV

The production cross section of electrons from semileptonic decays of beauty hadrons was measured at mid-rapidity (|y|&lt;0.8) in the transverse momentum range 1&lt;pT&lt;8 GeV/c with the ALICE experiment at the CERN LHC in pp collisions at a center of mass energy sqrt(s)=7 TeV using an integrated luminosity of 2.2 nb−1. Electrons from beauty hadron decays were selected based on the displacement of the decay vertex from the collision vertex. A perturbative QCD calculation agrees with the measurement within uncertainties. The data were extrapolated to the full phase space to determine the total cross section for the production of beauty quark–antiquark pairs
Polarized parton distributions at an electron–ion collider

We study the potential impact of inclusive deep-inelastic scattering data from a future electron–ion collider (EIC) on longitudinally polarized parton distributions (PDFs). We perform a PDF determination using the NNPDF methodology, based on sets of deep-inelastic EIC pseudodata, for different realistic choices of the electron and proton beam energies. We compare the results to our current polarized PDF set, NNPDFpol1.0 , based on a fit to fixed-target inclusive DIS data. We show that the uncertainties on the first moments of the polarized quark singlet and gluon distributions are substantially reduced in comparison to NNPDFpol1.0 , but also that more measurements may be needed to ultimately pin down the size of the gluon contribution to the nucleon spin
Flavor violating Z′ from SO(10) SUSY GUT in High-Scale SUSY

We propose an SO(10) supersymmetric grand unified theory (SUSY GUT), where the SO(10) gauge symmetry breaks down to SU(3)c×SU(2)L×U(1)Y×U(1)X at the GUT scale and U(1)X is radiatively broken at the SUSY-braking scale. In order to achieve the observed Higgs mass around 126 GeV and also to satisfy constraints on flavor- and/or CP-violating processes, we assume that the SUSY-breaking scale is O(100) TeV , so that the U(1)X breaking scale is also O(100) TeV . One big issue in the SO(10) GUTs is how to realize realistic Yukawa couplings. In our model, not only 16 -dimensional but also 10 -dimensional matter fields are introduced to predict the observed fermion masses and mixings. The Standard-Model quarks and leptons are linear combinations of the 16 - and 10 -dimensional fields so that the U(1)X gauge interaction may be flavor-violating. We investigate the current constraints on the flavor-violating Z′ interaction from the flavor physics and discuss prospects for future experiments
Horizontal rotation signals detected by “G-Pisa” ring laser for the Mw = 9.0, March 2011 Japan earthquake

We report the observation of the ground rotation induced by theMw=9.0, 11th of March 2011, Japan earthquake. The rotation measurements have been conducted with a ring laser gyroscope operating in a vertical plane, thus detecting rotations around the horizontal axis. Comparison of ground rotations with vertical accelerations from a co-located force{balance accelerometer shows excellent ring laser coupling at periods longer than 100s. Under the plane wave assumption, we derive a theoretical relationship between horizontal rotation and vertical acceleration for Rayleigh waves. Due to the oblique mounting of the gyroscope with respect to the wave direction{of{arrival, apparent velocities derived from the acceleration
/ rotation rate ratio are expected to be always larger than, or equal to the true wave propagation velocity. This hypothesis is con_rmed through comparison with fundamental{mode, Rayleigh wave phase velocities predicted for a standard Earth model
Mechanical and microstructural characterization of new nickel-free low modulus ß-type titanium wires during thermomechanical treatments

NiTi alloy is the only practical shape memory alloy (SMA) in biomedical use because of its excellent mechanical stability and functionality. However, it is estimated that between 4.5% and 28.5% of the population are hypersensitive to nickel metal, with a higher prevalence in females. Therefore, developing nickel-free low modulus ß-type titanium alloys showing shape memory or super elastic behavior would have a great interest in the biomaterials field. Homogeneous 127 µm diameter Ti25Hf21Nb wires were produced and compared to straight annealed Ti–50.8 at% Ni (Nitinol) and 90% cold-drawn 316L wires. Microstructural changes taking place during the heat treatment of cold-worked Ti25Hf21Nb wires were investigated. Large plastic deformation during wire drawing and subsequent annealing led to nano-crystallization and amorphization which may contribute to the observed superelasticity. Mechanical properties were characterized using cyclic uniaxial tension and rotary beam fatigue test modes. A modulus of elasticity of less than 60 GPa and axial recoverable strain of greater than 3% were observed with stress hysteresis resembling a reversible stress-induced martensitic transformation at higher temperatures. The new Ti25Hf21Nb alloy is an important candidate for developing Ni-free SMAs in the futurePeer ReviewedPostprint (author’s final draft
Government ownership of banks, institutions, and financial development.

Using a suitably modified locational model of banking, we examine the influence of institutions, such as deposit contract enforcement, in explaining the share of government owned banks in the banking system. We present cross-country evidence suggesting that institutional factors are relatively more important determinants of the share of state banks than political or historical ones. We argue that rather than privatizing or subsidizing state banks governments in developing countries should build institutions that foster the development of private banking
