Long-range Effect on the Curie Temperature of Ferroelectric Films

In this paper, the Curie temperature of ferroelectric films is studied using
spin-1/2 transverse Ising model with long-range interaction within the
framework of the effective-field theory. The dependence of the Curie
temperature on the thickness of the film, the surface interaction and the
transverse field were investigated. It is assumed that the long-range
interaction decays with the distance between the pseudo-spins as a power law.
The dependence of the Curie temperature and the critical transverse field on
the long-range exponent are obtained.Comment: 14 pages, 4 figures, accepted to publish on pss(b
Measurement of the Branching Ratio of the KL -> pi+pi- decay with the
  KLOE Detector

We present a measurement of the branching ratio of the CP violating decay
KL->pi+pi- performed by the KLOE experiment at the phi factory DAFNE. We use
328 pb-1 of data collected in 2001 and 2002, corresponding to ~ 150 million
tagged KL mesons. We find BR(KL->pi+pi-) = $(1.963 +/- 0.012 +/- 0.017)x 10^-3.
This branching ratio measurement is fully inclusive of final-state radiation.
Using the above result, we determine the modulus of the amplitude ratio
|\eta_{+-}| to be (2.219 +/- 0.013)x 10^{-3} and |\epsilon| to be (2.216 +/-
0.013)x 10^{-3}.Comment: Subitted to Phys. Lett.
Statistical Coalescence Model Analysis of J/psi Production in Pb+Pb
  Collisions at 158 A GeV

Production of J/\psi mesons in heavy ion collisions is considered within the
statistical coalescence model. The model is in agreement with the experimental
data of the NA50 Collaboration for Pb+Pb collisions at 158 A GeV in a wide
centrality range, including the so called ``anomalous'' suppression domain. The
model description of the J/psi data requires, however, strong enhancement of
the open charm production in central Pb+Pb collisions. This model prediction
may be checked in the future SPS runs.Comment: 13 pages, REVTeX, 2 PS-figure
Extraction of m_s and |V_us| from Hadronic Tau Decays

We review recent work to determine the strange quark mass m_s as well as the
proposal to determine |V_{us}| using hadronic tau decay data. The recent update
of the strange spectral function by OPAL and their moments of the invariant
mass distribution are employed. Our results are |V_us|=0.2208 +- 0.0034 and m_s
(2 GeV)=81 +- 22 MeV. Our result is already competitive to the standard
extraction of |V_us| from K_e3 decays and to the new proposals to determine it.
The error on V_us is dominated by experiment and will be eventually much
improved by the B-factories hadronic tau data.
  Ultimately, a simultaneous fit of both m_s and |V_us| to a set of moments of
the hadronic tau decays invariant mass distribution will provide one of the
most accurate determinations of these Standard Model parameters.Comment: Invited talk given by J.P. at TAU04, 14-17 September 2004, Nara

ALMA observations of cool dust in a low-metallicity starburst,
  SBS0335-052

We present Atacama Large Millimeter/submillimeter Array (ALMA) Cycle 0 Band 7
observations of an extremely metal-poor dwarf starburst galaxy in the Local
Universe, SBS0335-052 (12+log(O/H)~7.2). With these observations, dust is
detected at 870micron (ALMA Band 7), but 87% of the flux in this band is due to
free-free emission from the starburst. We have compiled a spectral energy
distribution (SED) of SBS0335-052 that spans almost 6 orders of magnitude in
wavelength and fit it with a spherical dust shell heated by a single-age
stellar population; the best-fit model gives a dust mass of (3.8+/-0.6)x10^4
Msun. We have also constructed a SED including Herschel archival data for
IZw18, another low-metallicity dwarf starburst (12+log(O/H)=7.17), and fit it
with a similar model to obtain a dust mass of (3.4+/-1.0)x10^2 Msun. Compared
with their atomic gas mass, the dust mass of SBS0335-052 far exceeds the
prediction of a linear trend of dust-to-gas mass ratio with metallicity, while
IZw18 falls far below. We use gas scaling relations to assess a putative
missing gas component in both galaxies and find that the missing, possibly
molecular, gas in SBS0335-052 is a factor of 6 times higher than the value
inferred from the observed HI column density; in IZw18 the missing component is
4 times smaller. Ultimately, despite their similarly low metallicity, the
differences in gas and dust column densities in SBS0335-052 and IZw18 suggest
that metal abundance does not uniquely define star-formation processes. At some
level, self-shielding and the survival of molecules may depend just as much on
gas and dust column density as on metallicity. The effects of low metallicity
may at least be partially compensated for by large column densities in the
interstellar medium.Comment: 15 pages, 11 figures, accepted for publication in A&
Long term variability of Cygnus X-1: VI. Energy-resolved X-ray
  variability 1999-2011

We present the most extensive analysis of Fourier-based X-ray timing
properties of the black hole binary Cygnus X-1 to date, based on 12 years of
bi-weekly monitoring with RXTE from 1999 to 2011. Our aim is a comprehensive
study of timing behavior across all spectral states, including the elusive
transitions and extreme hard and soft states. We discuss the dependence of the
timing properties on spectral shape and photon energy, and study correlations
between Fourier-frequency dependent coherence and time lags with features in
the power spectra. Our main results are: (a) The fractional rms in the
0.125-256 Hz range in different spectral states shows complex behavior that
depends on the energy range considered. It reaches its maximum not in the hard
state, but in the soft state in the Comptonized tail above 10 keV. (b) The
shape of power spectra in hard and intermediate states and the normalization in
the soft state are strongly energy dependent in the 2.1-15 keV range. This
emphasizes the need for an energy-dependent treatment of power spectra and a
careful consideration of energy- and mass-scaling when comparing the
variability of different source types, e.g., black hole binaries and AGN. PSDs
during extremely hard and extremely soft states can be easily confused for
energies above ~5 keV in the 0.125-256 Hz range. (c) The coherence between
energy bands drops during transitions from the intermediate into the soft state
but recovers in the soft state. (d) The time lag spectra in soft and
intermediate states show distinct features at frequencies related to the
frequencies of the main variability components seen in the power spectra and
show the same shift to higher frequencies as the source softens. [...abridged]
In particular, we discuss how the timing properties of Cyg X-1 can be used to
assess the evolution of variability with spectral shape in other black hole
binaries. [...abridged]Comment: A&A accepted; 20 pages, 16 figues (4 in appendix), 3 table
Generalized Causal Set d'Alembertians

We introduce a family of generalized d'Alembertian operators in D-dimensional
Minkowski spacetimes which are manifestly Lorentz-invariant, retarded, and
non-local, the extent of the nonlocality being governed by a single parameter
$\rho$. The prototypes of these operators arose in earlier work as averages of
matrix operators meant to describe the propagation of a scalar field in a
causal set. We generalize the original definitions to produce an infinite
family of ''Generalized Causet Box (GCB) operators'' parametrized by certain
coefficients $\{a,b_n\}$, and we derive the conditions on the latter needed for
the usual d'Alembertian to be recovered in the infrared limit. The continuum
average of a GCB operator is an integral operator, and it is these continuum
operators that we mainly study. To that end, we compute their action on plane
waves, or equivalently their Fourier transforms g(p) [p being the
momentum-vector]. For timelike p, g(p) has an imaginary part whose sign depends
on whether p is past or future-directed. For small p, g(p) is necessarily
proportional to p.p, but for large p it becomes constant, raising the
possibility of a genuinely Lorentzian perturbative regulator for quantum field
theory. We also address the question of whether or not the evolution defined by
the GCB operators is stable, finding evidence that the original 4D causal set
d'Alembertian is unstable, while its 2D counterpart is stable.Comment: 26 pages, 4 figure
Chaotic Hybrid Inflation with a Gauged B - L

In this paper we present a novel formulation of chaotic hybrid inflation in
supergravity. The model includes a waterfall field which spontaneously breaks a
gauged $U_1(B-L)$ at a GUT scale. This allows for the possibility of future
model building which includes the standard formulation of baryogenesis via
leptogenesis with the waterfall field decaying into right-handed neutrinos. We
have not considered the following issues in this short paper, i.e.
supersymmetry breaking, dark matter or the gravitino or moduli problems. Our
focus is on showing the compatibility of the present model with Planck, WMAP
and Bicep2 data.Comment: 11 pages, 3 figure
Myers-Perry black holes with scalar hair and a mass gap

We construct a family of asymptotically flat, rotating black holes with
scalar hair and a regular horizon, within five dimensional Einstein's gravity
minimally coupled to a complex, massive scalar field doublet. These solutions
are supported by rotation and have no static limit. They are described by their
mass $M$, two equal angular momenta $J_1=J_2\equiv J$ and a conserved Noether
charge $Q$, measuring the scalar hair. For vanishing horizon size the solutions
reduce to five dimensional boson stars. In the limit of vanishing Noether
charge density, the scalar field becomes point-wise arbitrarily small and the
geometry becomes, locally, arbitrarily close to that of a specific set of
Myers-Perry black holes (MPBHs); but there remains a global difference with
respect to the latter, manifest in a finite mass gap. Thus, the scalar hair
never becomes a linear perturbation of MPBHs. This is a qualitative difference
when compared to Kerr black holes with scalar hair~\cite{Herdeiro:2014goa}.
Whereas the existence of the latter can be anticipated in linear theory, from
the existence of scalar bound states on the Kerr geometry (i.e. scalar clouds),
the hair of these MPBHs is intrinsically non-linear.Comment: 11 pages, 6 figure
S-duality in N=4 Yang-Mills theories with general gauge groups

't Hooft construction of free energy, electric and magnetic fluxes, and of the partition function with twisted boundary conditions, is extended to the case of N=4 supersymmetric Yang-Mills theories based on arbitrary compact, simple Lie groups. The transformation of the fluxes and the free energy under S-duality is presented. We consider the partition function of N=4 for a particular choice of boundary conditions, and compute exactly its leading infrared divergence. We verify that this partition function obeys the transformation laws required by S-duality. This provides independent evidence in favor of S-duality in N=4 theories
On duality of the noncommutative extension of the Maxwell-Chern-Simons
  model

We study issues of duality in 3D field theory models over a canonical
noncommutative spacetime and obtain the noncommutative extension of the
Self-Dual model induced by the Seiberg-Witten map. We apply the dual projection
technique to uncover some properties of the noncommutative Maxwell-Chern-Simons
theory up to first-order in the noncommutative parameter. A duality between
this theory and a model similar to the ordinary self-dual model is
estabilished. The correspondence of the basic fields is obtained and the
equivalence of algebras and equations of motion are directly verified. We also
comment on previous results in this subject.Comment: Revtex, 9 pages, accepted for publication PL
Askey-Wilson relations and Leonard pairs

It is known that if $(A,B)$ is a Leonard pair, then the linear
transformations $A$, $B$ satisfy the Askey-Wilson relations A^2 B - b A B A + B
A^2 - g (A B+B A) - r B = h A^2 + w A + e I,
  B^2 A - b B A B + A B^2 - h (A B+B A) - s A = g B^2 + w B + f I, for some
scalars $b,g,h,r,s,w,e,f$. The problem of this paper is the following: given a
pair of Askey-Wilson relations as above, how many Leonard pairs are there that
satisfy those relations? It turns out that the answer is 5 in general. We give
the generic number of Leonard pairs for each Askey-Wilson type of Askey-Wilson
relations.Comment: 22 pages; corrected version; the example of Section 2 has the

GATE : a simulation toolkit for PET and SPECT

Monte Carlo simulation is an essential tool in emission tomography that can
assist in the design of new medical imaging devices, the optimization of
acquisition protocols, and the development or assessment of image
reconstruction algorithms and correction techniques. GATE, the Geant4
Application for Tomographic Emission, encapsulates the Geant4 libraries to
achieve a modular, versatile, scripted simulation toolkit adapted to the field
of nuclear medicine. In particular, GATE allows the description of
time-dependent phenomena such as source or detector movement, and source decay
kinetics. This feature makes it possible to simulate time curves under
realistic acquisition conditions and to test dynamic reconstruction algorithms.

Competition among Auctioneers in Large Markets

We analyse a multistage game of competition among auctioneers. First, the auctioneers commit to some reserve prices; second, the bidders enter one auction, if any; and finally, the auctions take place. We show that for any finite set of feasible reserve prices, each auctioneer announces a reserve price equal to his production cost if the numbers of auctioneers and bidders are sufficiently large, though finite. Our result supports the idea that optimal auctions may be quite simple. Our model also confirms previous results for some “limit” versions of the model by McAfee (Econometrica 61 (1993) 1281–1312), Peters (Rev. Econ. Stud. 64 (1997) 97–123), and Peters and Severinov (J.

Universally Finite Gravitational & Gauge Theories

It is well known that standard gauge theories are renormalizable in D=4 while
Einstein gravity is renormalizable in D=2. This is where the research in the
field of two derivatives theories is currently standing. We hereby present a
class of weakly non-local higher derivative gravitational and gauge theories
universally consistent at quantum level in any spacetime dimension. These
theories are unitary (ghost-free) and perturbatively renormalizable. Moreover,
we can always find a simple extension of these theories that is
super-renormalizable or finite at quantum level in even and odd spacetime
dimensions. Finally, we propose a super-renormalizable or finite theory for
gravity coupled to matter laying the groundwork for a "finite standard model of
particle physics" and/or a grand unified theory of all fundamental
interactions.Comment: 19 page
Implementing the De-thinning Method for High Energy Cosmic Rays
  Extensive Air Shower Simulations

To simulate the interaction of cosmic rays with the Earth atmosphere requires
highly complex computational resources and several statistical techniques have
been developed to simplify those calculations. It is common to implement the
thinning algorithms to reduce the number of secondary particles by assigning
weights to representative particles in the evolution of the cascade. However,
since this is a compression method with information loss, it is required to
recover the original flux of secondary particles without introduce artificial
biases. In this work we present the preliminary results of our version of the
de-thinning algorithm for the reconstruction of thinned simulations of
extensive air showers initiated by cosmic rays and photons in the energy range
$10^{15} < E/\mathrm{eV} < 10^{17}$.Comment: 5 pages, 2 figures, 1 table, Proceedings X SILAFAE Medellin-2014. To

Efficient Patterns for Model Checking Partial State Spaces in CTL & LTL

Compositional model checks of partial Kripke structures are efficient but incomplete as they may fail to recognize that all implementations satisfy the checked property. But if a property holds for such checks, it will hold in all implementations. Such checks are therefore under-approximations. In this paper we determine for which popular specification patterns, documented at a communityled pattern repository, this under-approximation is precise in that the converse relationship holds as well for all model checks. We find that many such patterns are indeed precise. Those that arent lose precision because of a sole propositional atom in mixed polarity. Hence we can compute, with linear blowup only, a semantic minimization in the same temporal logic whose efficient check renders the precise result for the original imprecise pattern. Thus precision can be secured for all patterns at low cost. © 2006 Elsevier B.V. All rights reserved
SHARDS: A global view of the star formation activity at z~0.84 and
  z~1.23

In this paper, we present a comprehensive analysis of star-forming galaxies
(SFGs) at intermediate redshifts (z~1). We combine the ultra-deep optical
spectro-photometric data from the Survey for High-z Absorption Red and Dead
Sources (SHARDS) with deep UV-to-FIR observations in the GOODS-N field.
Exploiting two of the 25 SHARDS medium-band filters, F687W17 and F823W17, we
select [OII] emission line galaxies at z~0.84 and z~1.23 and characterize their
physical properties. Their rest-frame equivalent widths
(EW$_{\mathrm{rf}}$([OII])), line fluxes, luminosities, star formation rates
(SFRs) and dust attenuation properties are investigated. The evolution of the
EW$_{\mathrm{rf}}$([OII]) closely follows the SFR density evolution of the
universe, with a trend of EW$_{\mathrm{rf}}$([OII])$\propto$(1+z)$^3$ up to
redshift z~1, followed by a possible flattening. The SF properties of the
galaxies selected on the basis of their [OII] emission are compared with
complementary samples of SFGs selected by their MIR and FIR emission, and also
with a general mass-selected sample of galaxies at the same redshifts. We
demonstrate observationally that the UVJ diagram (or, similarly, a cut in the
specific SFR) is only partially able to distinguish the quiescent galaxies from
the SFGs. The SFR-M$_*$ relation is investigated for the different samples,
yelding a logarithmic slope ~1, in good agreement with previous results. The
dust attenuations derived from different SFR indicators (UV(1600), UV(2800),
[OII], IR) are compared and show clear trends with respect to both the stellar
mass and total SFR, with more massive and highly star-forming galaxies being
affected by stronger dust attenuation.Comment: Replaced to match the accepted version (24 pages, 1 table, 17

Implementation of an end-to-end standard-based patient monitoring solution

A proof-of-concept design of a patient monitoring solution for intensive care unit environments has been presented. It is end-to-end standard-based, using ISO/IEEE 11073 (X73) in the bedside environment and EN13606 to communicate the information to an electronic healthcare record (EHR) server. At the bedside end, the system is a plug-and-play sensor network communicating with a gateway that collects medical information and sends the data to a monitoring server. The monitoring server transforms this information into an EN13606 extract to be stored on the EHR server. The system has been implemented to comply with the last X73 and EN13606 available versions and tested in a laboratory environment to demonstrate the feasibility of an end-to-end standard-based solution.This research work has been financially supported in part by projects PI05-0847, PI05-1416 and G03/117 from Fondo de investigaciones Sanitarias, Ministerio de Sanidad y Consumo (Spanish Government); TSI2005-07068-C02-01 and TSI2004-04940-C02-01 from Ministerio de Educatio´n y Ciencia

Contesting climate justice in the city : examining politics and practice in urban climate change experiments

This paper draws on work undertaken through Harriet Bulkeley's ESRC Climate Change Fellowship, Urban Transitions: climate change, global cities and the transformation of socio-technical systems (ESRC RES-066-27-0002)Debates about climate justice have mainly occurred at the international scale, and have focussed on the rights and responsibilities of nation-states to either be protected from the effects of climate change, or to take action to reduce emissions or support adaptation. In this paper, we argue that it is both productive and necessary to examine how climate justice is being pursued at the urban scale, which brings into focus the need for attention to issues of recognition as well as rights and responsibilities. Building on work from environmental justice, which has conceptualized justice as trivalent, we propose that climate justice can be understood as a pyramid, the faces of which are distributions, procedures, rights, responsibilities and recognition. We then apply this conceptual framework to examine climate change interventions in five cities; Bangalore, Monterrey, Hong Kong, Philadelphia and Berlin. Arguing that the politics and practices of urban climate change interventions are constantly engaging with and refracting the idea of justice, we examine how justice was articulated, practiced and contested across our cases. The perspective of recognition emerges as a particularly useful entry point through which to explore the types of rights, responsibilities, distributions and procedures required to respond justly to climate change. We conclude by reflecting on our framework, arguing that it is useful both as an analytical device to interrogate climate justice and to shape the design of climate change interventions which seek to ensure climate justice.Publisher PDFPeer reviewe
Microglia-Secreted Galectin-3 Acts as a Toll-like Receptor 4 Ligand and Contributes to Microglial Activation.

Inflammatory response induced by microglia plays aÂ critical role in the demise of neuronal populations in neuroinflammatory diseases. Although the role of toll-like receptor 4 (TLR4) in microglia's inflammatory response is fully acknowledged, little is known about endogenous ligands that trigger TLR4 activation. Here, we report that galectin-3 (Gal3) released by microglia acts as an endogenous paracrine TLR4 ligand. Gal3-TLR4 interaction was further confirmed in a murine neuroinflammatory model (intranigral lipopolysaccharide [LPS] injection) and in human stroke subjects. Depletion of Gal3 exerted neuroprotective and anti-inflammatory effects following global brain ischemia and in the neuroinflammatory LPS model. These results suggest that Gal3-dependent-TLR4 activation could contribute to sustained microglia activation, prolonging the inflammatory response in the brain
