Differences Between Victims of Bullying and Non-victims on Levels of Paranoid Ideation and Persecutory Symptoms, the Presence of Aggressive Traits, the Display of Social Anxiety and the Recall of Childhood Abuse Experiences in a Portuguese Mixed Clinical Sample.

BACKGROUND:\ud
\ud
Bullying has been considered as a traumatic experience that can lead to paranoid ideation in students (Campbell and Morrison, 2007). This study aimed to explore differences concerning experiences of childhood trauma, the display of social anxiety behaviours, paranoid ideation, and aggressive traits and behaviour in a mixed clinical population with and without persecutory delusions, between individuals who reported being victims of bullying versus those who did not.\ud
METHOD:\ud
\ud
A total of 61 individuals with diagnoses of paranoid schizophrenia and social anxiety disorder were given a battery of questionnaires that measured bullying experiences, childhood abuse and experiences of threat and subordination, paranoid ideation, social anxiety behaviours, shame, and aggressive traits and behaviours.\ud
RESULTS:\ud
\ud
Data on the differences between the victims of bullying and non-victims, in terms of recalling being bullied, showed higher scores on childhood abuse, experiences of threat and subordination within the family, aggressive traits and higher display of persecutory symptoms and less social anxiety behaviours.\ud
CONCLUSION:\ud
\ud
Bullying is a traumatic phenomenon that is reported by people who suffer from persecutory delusions to a higher degree than those who do not. This study, thus, gives support to the idea that childhood abuse within the family is associated with bullying experiences and that a traumatic infancy may lead to the use of aggressive traits and behaviours to deal with a threatening environment (Bentall and Fernyhough, 2008). This argument raises clinical issues regarding anger management and addressing bullying experiences in individuals with persecutory ideation.

Decay of polarized muon at rest as a source of polarized neutrino beam

In this paper, we indicate the theoretical possibility of using the decay of
polarized muons at rest as a source of the transversely polarized electron
antineutrino beam. Such a beam can be used to probe new effects beyond standard
model. We mean here new tests concerning CP violation, Lorentz structure and
chirality structure of the charged current weak interactions. The main goal is
to show how the energy and angular distribution of the electron antineutrinos
in the muon rest frame depends on the transverse components of the antineutrino
beam polarization. Our analysis is model-independent and consistent with the
current upper limits on the non-standard couplings. The results are presented
in a limit of infinitesimally small mass for all particles produced in the
decay.Comment: elsart style, 11 pages, 2 eps figures, submitted do publicatio
Polyakov loop and the color-flavor locked phase of Quantum
  Chromodynamics

We consider the Polyakov Nambu Jona Lasinio model with three massless quarks
at high density and moderate temperature in the superconductive color flavor
locking phase. We compute the critical temperature $T_c$ as a function of the
baryonic chemical potential for the phase transition from the superconductive
state to the normal phase. We find that $T_c$ is higher by a factor 1.5 -2 in
comparison to the model containing no Polyakov loop. We also compute the
specific heat $C_v$ near the second order phase transition and we show that the
inclusion of the Polyakov loop does not change the value of the critical
exponent.Comment: 7 pages, 2 figures, RevTeX4 styl
Towards the continuous limit of cluster integrable systems.\ud

We initiate the study of how to extend the correspondence between dimer models and (0 + 1)-dimensional cluster integrable systems to (1 + 1) and (2 + 1)-dimensional continuous integrable field theories, addressing various points that are necessary for achieving this goal. We first study how to glue and split two integrable systems, from the perspectives of the spectral curve, the resolution of the associated toric Calabi-Yau 3-folds and Higgsing in quiver theories on D3-brane probes. We identify a continuous parameter controlling the decoupling between the components and present two complementary methods for determining the dependence on this parameter of the dynamical variables of the integrable system. Interested in constructing systems with an infinite number of degrees of freedom, we study the combinatorics of integrable systems built up from a large number of elementary components, and introduce a toy model capturing important features expected to be present in a continuous reformulation of cluster integrable systems
Bayesian multiscale analysis of images modeled as Gaussian Markov random fields

A Bayesian multiscale technique for the detection of statistically significant features in noisy images is proposed. The prior is defined as a stationary intrinsic Gaussian Markov random field on a toroidal graph, which enables efficient computation of the relevant posterior marginals. Hence the method is applicable to large images produced by modern digital cameras. The technique is demonstrated in two examples from medical imaging. We model digital images as intrinsic Gaussian Markov random fields. This Bayesian scale-space method detects significant gradient and curvature. Efficient computation is achieved by defining images on a toroidal graph. The technique is successfully demonstrated in two examples from medical imaging
SDiff(2) and uniqueness of the Plebanski equation

The group of area preserving diffeomorphisms showed importance in the problems of self-dual gravity and integrability theory. We discuss how representations of this infinite-dimensional Lie group can arise in mathematical physics from pure local considerations. Then using Lie algebra extensions and cohomology we derive the second Plebański equation and its geometry. We do not use Kähler or other additional structures but obtain the equation solely from the geometry of area preserving transformations group. We conclude that the Plebański equation is Lie remarkable
Searching for the dimension of valued preference relations.

The more information a preference structure gives, the more sophisticated representation techniques are necessary, so decision makers can have a global view of data and therefore a comprehensive understanding of the problem they are faced with. In this paper we propose to explore valued preference relations by means of a search for the number of underlying criteria allowing its representation in real space. A general representation theorem for arbitrary crisp binary relations is obtained, showing the difference in representation between incomparability-related to the intersection operator-and other inconsistencies-related to the union operator. A new concept of dimension is therefore proposed, taking into account inconsistencies in source of information. Such a result is then applied to each alpha-cut of valued preference relations.

On the isolated dwarf galaxies: from cuspy to flat dark matter density
  profiles and metallicity gradients

The chemodynamical evolution of spherical multi-component self-gravitating
models for isolated dwarf galaxies is studied. We compare their evolution with
and without feedback effects from star formation processes. We find that
initially cuspy dark matter profiles flatten with time as a result of star
formation, without any special tuning conditions. Thus the seemingly flattened
profiles found in many dwarfs do not contradict the cuspy profiles predicted by
cosmological models. We also calculate the chemical evolution of stars and gas,
to permit comparisons with observational data.Comment: Accepted the 28/01/1
Hybrid tractability of soft constraint problems

The constraint satisfaction problem (CSP) is a central generic problem in
computer science and artificial intelligence: it provides a common framework
for many theoretical problems as well as for many real-life applications. Soft
constraint problems are a generalisation of the CSP which allow the user to
model optimisation problems. Considerable effort has been made in identifying
properties which ensure tractability in such problems. In this work, we
initiate the study of hybrid tractability of soft constraint problems; that is,
properties which guarantee tractability of the given soft constraint problem,
but which do not depend only on the underlying structure of the instance (such
as being tree-structured) or only on the types of soft constraints in the
instance (such as submodularity). We present several novel hybrid classes of
soft constraint problems, which include a machine scheduling problem,
constraint problems of arbitrary arities with no overlapping nogoods, and the
SoftAllDiff constraint with arbitrary unary soft constraints. An important tool
in our investigation will be the notion of forbidden substructures.Comment: A full version of a CP'10 paper, 26 page
Automation of one-loop QCD corrections

We present the complete automation of the computation of one-loop QCD
corrections, including UV renormalization, to an arbitrary scattering process
in the Standard Model. This is achieved by embedding the OPP integrand
reduction technique, as implemented in CutTools, into the MadGraph framework.
By interfacing the tool so constructed, which we dub MadLoop, with MadFKS, the
fully automatic computation of any infrared-safe observable at the
next-to-leading order in QCD is attained. We demonstrate the flexibility and
the reach of our method by calculating the production rates for a variety of
processes at the 7 TeV LHC.Comment: 64 pages, 12 figures. Corrected the value of m_Z in table 1. In table

Accurate simulation estimates of phase behaviour in ternary mixtures
  with prescribed composition

This paper describes an isobaric semi-grand canonical ensemble Monte Carlo
scheme for the accurate study of phase behaviour in ternary fluid mixtures
under the experimentally relevant conditions of prescribed pressure,
temperature and overall composition. It is shown how to tune the relative
chemical potentials of the individual components to target some requisite
overall composition and how, in regions of phase coexistence, to extract
accurate estimates for the compositions and phase fractions of individual
coexisting phases. The method is illustrated by tracking a path through the
composition space of a model ternary Lennard-Jones mixture.Comment: 6 pages, 3 figure
A search for hidden white dwarfs in the ROSAT EUV survey II: Discovery
  of a distant DA+F6/7V binary system in a direction of low density neutral
  hydrogen

We report the results of our final search for hot white dwarfs in unresolved,
Sirius-type, binary systems with IUE. One new system, RE J0500-364 (DA+F6/7V),
has been identified. This star appears to lie at a distance of between
500-1000pc, making it one of the most distant white dwarfs, if not the most
distant, to be detected in the EUV surveys. The very low line-of-sight neutral
hydrogen volume density to this object could place a lower limit on the length
of the Beta CMa interstellar tunnel of diffuse gas, which stretches away from
the Local Bubble in a similar direction to RE J0500-364.Comment: 1 LaTex file plus 15 figures; accepted for publication in Monthly

Light Propagation in inhomogeneous Universes

Using a multi-plane lensing method that we have developed, we follow the
evolution of light beams as they propagate through inhomogeneous universes. We
use a P3M code to simulate the formation and evolution of large-scale
structure. The resolution of the simulations is increased to sub-Megaparsec
scales by using a Monte Carlo method to locate galaxies inside the
computational volume according to the underlying particle distribution. The
galaxies are approximated by isothermal spheres, with each morphological type
having its own distribution of masses and core radii. The morphological types
are chosen in order to reproduce the observed morphology-density relation. This
algorithm has an effective resolution of 9 orders of magnitudes in length, from
the size of superclusters down to the core radii of the smallest galaxies.
  We consider cold dark matter models normalized to COBE, and perform a large
parameter survey by varying the cosmological parameters Omega_0, lambda_0, H_0,
and n (the tilt of the primordial power spectrum). The values of n are chosen
by imposing particular values or sigma_8, the rms mass fluctuation at a scale
of 8/h Mpc. We use the power spectrum given by Bunn & White. This is the
largest parameter survey ever done is this field.Comment: 3 pages, gzip'ed tar file, including TeX source (not Latex). To be

Rotating matter in general relativity -- stationary state I

Stationary rotating matter configurations in general relativity are
considered. A formalism for general stationary space times is developed.
Axisymmetric systems are discussed by the use of a nonholonomic and nonrigid
frame in the three-space of the time-like Killing trajectories. Two symmetric
and trace-free tensors are constructed. They characterize a class of matter
states in which both the interior Schwarzschild and the Kerr solution are
contained. Consistency relations for this class of perfect fluids are derived.
Incompressible fluids characterized by these tensors are investigated, and one
differentially rotating solution is found.Comment: 25 pages, REVTe
Measurement of D^(*+-) Meson Production and F_2^c in Deep-Inelastic
  Scattering at HERA

The inclusive production of D^{*+-}(2010) mesons in deep-inelastic scattering
is studied with the H1 detector at HERA. In the kinematic region 1<Q^2<100
GeV^2 and 0.05<y<0.7 an e^+p cross section for inclusive D^(*+-) meson
production of 8.50+- 0.42 (stat.)^(+1.21)_(-1.00) (syst.) nb is measured in the
visible range p_(tD^*)>1.5 GeV and |\eta_(D^*)|<1.5. Single and double
differential inclusive D^(*+-) meson cross sections are compared to
perturbative QCD calculations in two different evolution schemes. The charm
contribution to the proton structure, F_2^c(x,Q^2), is determined by
extrapolating the visible charm cross section to the full phase space. This
contribution is found to rise from about 10% at Q^2 = 1.5 GeV^2 to more than
25% at Q^2 = 60 GeV^2 corresponding to x values ranging from 5*10^(-5) to
3*10^(-3)$.Comment: 23 pages, 7 figures, 3 table
Unitarity of Compactified Five Dimensional Yang-Mills Theory

Compactified five dimensional Yang-Mills theory results in an effective
four-dimensional theory with a Kaluza-Klein (KK) tower of massive vector
bosons. We explicitly demonstrate that the scattering of the massive vector
bosons is unitary at tree-level for low energies, and analyze the relationship
between the unitarity violation scale in the KK theory and the
nonrenormalizability scale in the five dimensional gauge theory. In the
compactified theory, low-energy unitarity is ensured through an interlacing
cancellation among contributions from the relevant KK levels. Such
cancellations can be understood using a Kaluza-Klein equivalence theorem which
results from the geometric ``Higgs'' mechanism of compactification. In these
theories, the unitarity violation is delayed to energy scales higher than the
customary limit through the introduction of additional vector bosons rather
than Higgs scalars.Comment: 10 pages, 1 eps figure, discussion of deconstruction expanded,

Branching laws for Verma modules and applications in parabolic geometry.
  I

We initiate a new study of differential operators with symmetries and combine
this with the study of branching laws for Verma modules of reductive Lie
algebras. By the criterion for discretely decomposable and multiplicity-free
restrictions of generalized Verma modules [T. Kobayashi,
http://dx.doi.org/10.1007/s00031-012-9180-y {Transf. Groups (2012)}], we are
brought to natural settings of parabolic geometries for which there exist
unique equivariant differential operators to submanifolds. Then we apply a new
method (F-method) relying on the Fourier transform to find singular vectors in
generalized Verma modules, which significantly simplifies and generalizes many
preceding works. In certain cases, it also determines the Jordan--H\"older
series of the restriction for singular parameters. The F-method yields an
explicit formula of such unique operators, for example, giving an intrinsic and
new proof of Juhl's conformally invariant differential operators [Juhl,
http://dx.doi.org/10.1007/978-3-7643-9900-9 {Progr. Math. 2009}] and its
generalizations. This article is the first in the series, and the next ones
include their extension to curved cases together with more applications of the
F-method to various settings in parabolic geometries
The O3N2 and N2 abundance indicators revisited: improved calibrations
  based on CALIFA and Te-based literature data

The use of IFS is since recently allowing to measure the emission line fluxes
of an increasingly large number of star-forming galaxies both locally and at
high redshift. The main goal of this study is to review the most widely used
empirical oxygen calibrations, O3N2 and N2, by using new direct abundance
measurements. We pay special attention to the expected uncertainty of these
calibrations as a function of the index value or abundance derived and the
presence of possible systematic offsets. This is possible thanks to the
analysis of the most ambitious compilation of Te-based HII regions to date.
This new dataset compiles the Te-based abundances of 603 HII regions extracted
from the literature but also includes new measurements from the CALIFA survey.
Besides providing new and improved empirical calibrations for the gas
abundance, we also present here a comparison between our revisited calibrations
with a total of 3423 additional CALIFA HII complexes with abundances derived
using the ONS calibration by Pilyugin et al. (2010). The combined analysis of
Te-based and ONS abundances allows us to derive their most accurate calibration
to date for both the O3N2 and N2 single-ratio indicators, in terms of all
statistical significance, quality and coverage of the space of parameters. In
particular, we infer that these indicators show shallower abundance
dependencies and statistically-significant offsets compared to those of Pettini
and Pagel (2004), Nagao et al. (2006) and P\'erez-Montero and Contini (2009).
The O3N2 and N2 indicators can be empirically applied to derive oxygen
abundances calibrations from either direct abundance determinations with random
errors of 0.18 and 0.16, respectively, or from indirect ones (but based on a
large amount of data) reaching an average precision of 0.08 and 0.09 dex
(random) and 0.02 and 0.08 dex (systematic; compared to the direct
estimations),respectively.Comment: 12 pages, 5 figures, accepted for publication in A&
Hot subdwarf stars in close-up view IV. Helium abundances and the $^3$He
  isotopic anomaly of subdwarf B star

Atmospheric parameters and helium abundances of 44 bright subdwarf B stars
have been determined. More than half of our sample consists of newly discovered
stars from the Edinburgh Cape survey. We showed that effective temperatures and
surface gravities can be derived from high resolution echelle spectra with
sufficient accuracy. Systematic uncertainties have been determined by comparing
the parameters derived from the high resolution data with the ones derived from
medium resolution spectra. Helium abundances have been measured with high
accuracy. Besides the known correlation of helium abundance with temperature,
two distinct sequences in helium abundance have been confirmed. Significant
isotopic shifts of helium lines due to an enrichment in $^{3}$He have been
found in the spectra of 8 sdBs. Most of these stars cluster in a small
temperature range between $27\,000\,{\rm K}$ and $31\,000\,{\rm K}$ very
similar to the known $^{3}$He-rich main sequence B stars, which also cluster in
such a small strip, but at different temperatures. Both the helium sequences
and the isotopic anomaly are discussed.Comment: 12 pages, A&A accepte
Holographic entanglement and causal information in coherent states

Scalar solitons in global AdS4 are holographically dual to coherent states
carrying a non-trivial condensate of a scalar operator. We study the
holographic information content of these states, focusing on a particular
spatial region, by examining the entanglement entropy and causal holographic
information. We show generically that whenever the dimension of the condensed
operator is sufficiently low (characterized by the double-trace operator
becoming relevant), such coherent states have lower entanglement and causal
holographic information than the vacuum state of the system, despite having
greater energy. We also use these geometries to illustrate the fact that causal
wedges associated with a simply-connected boundary region can have non-trivial
topology even in causally trivial spacetimes.Comment: 43 pages, 19 figures; v2: typos fixed, published version; v3:

Comparing and Counting Logs in Direct and Effective Methods of
  Resummation

We compare methods to resum logarithms in event shape distributions as they
have been used in perturbative QCD directly and in effective field theory. We
demonstrate that they are equivalent. In showing this equivalence, we are able
to put standard soft-collinear effective theory (SCET) formulae for cross
sections in momentum space into a novel form more directly comparable with
standard QCD formulae, and endow the QCD formulae with dependence on separated
hard, jet, and soft scales, providing potential ways to improve estimates of
theoretical uncertainty. We show how to compute cross sections in momentum
space to keep them as accurate as the corresponding expressions in Laplace
space. In particular, we point out that that care is required in truncating
differential distributions at N$^k$LL accuracy to ensure they match the
accuracy of the corresponding cumulant or Laplace transform. We explain how to
avoid such mismatches at N$^k$LL accuracy, and observe why they can also be
avoided by working to N$^k$LL$'$ accuracy.Comment: 65 pages plus Appendices, 8 figures, uses JHEP style. v2: improved
