On a Lorentz-Invariant Interpretation of Noncommutative Space-Time and
  Its Implications on Noncommutative QFT

By invoking the concept of twisted Poincar\' e symmetry of the algebra of
functions on a Minkowski space-time, we demonstrate that the noncommutative
space-time with the commutation relations $[x_\mu,x_\nu]=i\theta_{\mu\nu}$,
where $\theta_{\mu\nu}$ is a {\it constant} real antisymmetric matrix, can be
interpreted in a Lorentz-invariant way. The implications of the twisted
Poincar\'e symmetry on QFT on such a space-time is briefly discussed. The
presence of the twisted symmetry gives justification to all the previous
treatments within NC QFT using Lorentz invariant quantities and the
representations of the usual Poincar\'e symmetry.Comment: 12 pages, one reference adde
Properties of scalar-isoscalar mesons from multichannel interaction analysis below 1800 MeV

Scalar-isoscalar mesons are studied using an unitary model in three channels: pi-pi, K-anti K and an effective 2pi-2pi. All the solutions, fitted to the pi-pi and K-anti K data, exhibit a wide f0(500), a narrow f0(980) and two relatively narrow resonances, lying on different sheets between 1300 MeV and 1500 MeV. These latter states are similar to the f0(1370) and f0(1500) seen in experiments at CERN. Branching ratios are compared with available data. We have started investigations of some crossing symmetry and chiral constraints imposed near the pi-pi threshold on the scalar-isoscalar, scalar-isotensor and P-wave pi-pi amplitudes
Full one-loop electroweak radiative corrections to single Higgs production in e+ e-

We present the full ${{\cal O}}(\alpha)$ electroweak radiative corrections to single Higgs production in \epemt. This takes into account the full one-loop corrections as well as the effects of hard photon radiation. We include both the fusion and Higgs-strahlung processes. The computation is performed with the help of {\tt GRACE-loop} where we have implemented a generalised non-linear gauge fixing condition. The latter includes 5 gauge parameters that can be used for checks on our results. Besides the UV, IR finiteness and gauge parameter independence checks it proves also powerful to test our implementation of the 5-point function. We find that for a 500GeV machine and a light Higgs of mass 150GeV, the total ${{\cal O}}(\alpha)$ correction is small when the results are expressed in terms of $\alpha_{{\rm QED}}$. The total correction decreases slightly for higher energies. For moderate centre of mass energies the total ${{\cal O}}(\alpha)$ decreases as the Higgs mass increases, reaching -10% for $M_H=350$GeV and $\sqrt{s}=500$GeV. In order to quantify the genuine weak corrections we have subtracted the universal virtual and bremsstrahlung correction from the full ${{\cal O}}(\alpha)$. We find, for $M_H=150$GeV, a weak correction slowly decreasing from -2% to -4% as the energy increases from $\sqrt{s}=300$GeV to $\sqrt{s}=1$TeV after expressing the tree-level results in terms of $G_\mu
Confining String with Topological Term

We consider several aspects of `confining strings', recently proposed to
describe the confining phase of gauge field theories.
  We perform the exact duality transformation that leads to the confining
string action and show that it reduces to the Polyakov action in the
semiclassical approximation. In 4D we introduce a `$\theta$-term' and compute
the low-energy effective action for the confining string in a derivative
expansion. We find that the coefficient of the extrinsic curvature (stiffness)
is negative, confirming previous proposals. In the absence of a $\theta$-term,
the effective string action is only a cut-off theory for finite values of the
coupling e, whereas for generic values of $\theta$, the action can be
renormalized and to leading order we obtain the Nambu-Goto action plus a
topological `spin' term that could stabilize the system.Comment: 11 pages, harvma
Reinterpretation of Faddeev-Niemi Knot in Skyrme Theory

We identify the Faddeev-Niemi knot in Skyrme theory as a vortex ring made of
a helical baby skyrmion (a twisted chromomagnetic vortex which is periodic in
$z$-coodinate) with the periodic ends connected together. This allows us to
interpret the knot as two quantized magnetic flux rings linked together, the
first one winding the second $m$ times and the second one winding the first $n$
times, whose linking number $mn$ is fixed by the Chern-Simon index of the
magnetic potential. This interpretation strongly suggests that the Skyrme
theory could also describe a very interesting low energy physics in a
completely different environment, which puts the theory in a totally new
perspective.Comment: 4 pages, 1 figure, PLB in pres
A Novel DNA Repair Disorder With Thrombocytopenia, Nephrosis, and Features Overlapping Cockayne Syndrome

We report on four siblings with Cockayne-like syndrome with thrombocytopenia and nephrotic syndrome. The parents were healthy and consanguineous, consistent with an autosomal recessive mode of disease inheritance. UV irradiation of fibroblasts revealed an intermediate sensitivity between normal and standard Cockayne syndrome (CS) control cells. A genome-wide linkage scan conducted using Affymetrix 10K arrays provided exclusion of the known CS genes in the family, and evidence that the disease gene maps to 1p33-p31.1. Thrombocytopenia has not previously been linked with CS, but two patients with CS in association with nephrotic syndrome have previously been documented and the phenotypes are compared with the patients described here. We suggest that this Cockayne-like phenotype with thrombocytopenia and nephrotic syndrome may be a novel DNA repair disorder, and propose that further investigation of other affected families may help identify the causative genetic defect.

Contributions of flavor violating couplings of a Higgs boson to $pp\to
  WW$

We study contributions to $pp\to W^+W^- \to \ell\nu_\ell
\ell^\prime\nu_{\ell^\prime}$ in models with a new Higgs boson, $H$, and a
neutral lepton, $\nu_{4}$, with couplings $H-\nu_{4}-\nu_{\mu}$ and
$W-\nu_{4}-\mu$ through the process $pp \to H \to \nu_4 \nu_\mu \to W \mu
\nu_\mu \to \ell\nu_\ell \mu \nu_\mu$. Contrary to naive expectations, we find
that contributions to $pp\to WW$ can be very large while satisfying constraints
from standard $H\to WW$ and $H\to\gamma\gamma$ searches. Even the excess
observed by ATLAS in $pp\to WW$, if taken at face value, can be easily
accommodated. The various kinematic distributions fit nicely the experimentally
determined ones. This scenario can arise for example in a two Higgs doublet
model with vectorlike leptons.Comment: 16 pages, 5 figure
Probing Bino-Gluino Coannihilation at the LHC

It has been widely known that bino-like dark matter in the supersymmetric
(SUSY) theories in general suffers from over-production. The situation can be
drastically improved if gluinos have a mass slightly heavier than the bino dark
matter as they reduce the dark matter abundance through coannihilation. In this
work, we consider such a bino-gluino coannihilation scenario in high-scale SUSY
models, which can be actually realized when the squark-mass scale is less than
100-1000 TeV. We study the prospects for exploring this bino-gluino
coannihilation scenario at the LHC. We show that the searches for long-lived
colored particles with displaced vertices offer a strong tool to test this
scenario in collider experiments.Comment: 15 pages, 4 figure
From End-User's Requirements to Web Services Retrieval: A Semantic and
  Intention-Driven Approach

In this paper, we present SATIS, a framework to derive Web Service
specifications from end-user's requirements in order to opera-tionalise
business processes in the context of a specific application domain. The aim of
SATIS is to provide to neuroscientists, which are not familiar with computer
science, a complete solution to easily find a set of Web Services to implement
an image processing pipeline. More precisely, our framework offers the
capability to capture high-level end-user's requirements in an iterative and
incremental way and to turn them into queries to retrieve Web Services
description. The whole framework relies on reusable and combinable elements
which can be shared out by a community of users sharing some interest or
problems for a given topic. In our approach, we adopt Web semantic languages
and models as a unified framework to deal with end-user's requirements and Web
Service descriptions in order to take advantage of their reasoning and
traceability capabilities.Comment: {\'e}galement rapport de recherche I3S/RR--2010-03--FR in

Classical-physics applications for Finsler $b$ space

The classical propagation of certain Lorentz-violating fermions is known to
be governed by geodesics of a four-dimensional pseudo-Finsler $b$ space
parametrized by a prescribed background covector field. This work identifies
systems in classical physics that are governed by the three-dimensional version
of Finsler $b$ space and constructs a geodesic for a sample non-constant choice
for the background covector. The existence of these classical analogues
demonstrates that Finsler $b$ spaces possess applications in conventional
physics, which may yield insight into the propagation of SME fermions on curved
manifolds.Comment: 8 pages, 2 figures, accepted for publication in Physics Letters
Chaotic strings in a near Penrose limit of AdS$_5\times T^{1,1}$

We study chaotic motions of a classical string in a near Penrose limit of
AdS$_5\times T^{1,1}$. It is known that chaotic solutions appear on $R\times
T^{1,1}$, depending on initial conditions. It may be interesting to ask whether
the chaos persists even in Penrose limits or not. In this paper, we show that
sub-leading corrections in a Penrose limit provide an unstable separatrix, so
that chaotic motions are generated as a consequence of collapsed
Kolmogorov-Arnold-Moser (KAM) tori. Our analysis is based on deriving a reduced
system composed of two degrees of freedom by supposing a winding string ansatz.
Then, we provide support for the existence of chaos by computing Poincare
sections. In comparison to the AdS$_5\times T^{1,1}$ case, we argue that no
chaos lives in a near Penrose limit of AdS$_5\times$S$^5$, as expected from the
classical integrability of the parent system.Comment: 19 pages, 9 figures, LaTeX, v2: typos corrected and some

Superconformal partial waves in Grassmannian field theories

We derive superconformal partial waves for all scalar four-point functions on
a super Grassmannian space Gr(m|n,2m|2n) for all m,n. This family of four-point
functions includes those of all (arbitrary weight) half BPS operators in both
N=4 SYM (m=n=2) and in N=2 superconformal field theories in four dimensions
(m=2,n=1) on analytic superspace. It also includes four-point functions of all
(arbitrary dimension) scalar fields in non-supersymmetric conformal field
theories (m=2,n=0) on Minkowski space, as well as those of a certain class of
representations of the compact SU(2n) coset spaces. As an application we then
specialise to N=4 SYM and use these results to perform a detailed
superconformal partial wave analysis of the four- point functions of arbitrary
weight half BPS operators. We discuss the non-trivial separation of protected
and unprotected sectors for the <2222>, <2233> and <3333> cases in an SU(N)
gauge theory at finite N. The <2233> correlator predicts a non-trivial
protected twist four sector for <3333> which we can completely determine using
the knowledge that there is precisely one such protected twist four operator
for each spin.Comment: Minor corrections and a new subsection 3.5.1 giving explicit forms
  for the superconformal partial waves in N=4 SYM in terms of one- and
  two-variable functions for easier comparison with other approache
Reconceptualizing ‘effectiveness’ in environmental management: can we measure values-related achievements?

There have been recent calls for a shift to an evidence-based paradigm in environmental management, grounded in systematic monitoring and evaluation, but achieving this will be complex and difficult. Evaluating the educational components of environmental initiatives presents particular challenges, because these programs often have multiple concurrent goals and may value ‘human outcomes’, such as value change, which are intangible and difficult to quantify. This paper describes a fresh approach based on co-creating an entirely new values-based assessment framework with expert practitioners worldwide. We first discuss the development of a generic framework of ‘Proto-Indicators’ (reference criteria constituting prototypes for measurable indicators), and then demonstrate its application within a reforestation project in Mexico where indicators and assessment tools were localized to enhance context-relevance. Rigorously derived using unitary validity, with an emphasis on relevance, practicability and logical consistency from user perspectives, this framework represents a step-wise advance in the evaluation of non-formal EE / ESD programs. This article also highlights three important principles with broader implications for evaluation, valuation and assessment processes within environmental management: namely peer-elicitation, localizability, and an explicit focus on ethical values. We discuss these principles in relation to the development of sustainability indicators at local and global levels, especially in relation to post-2015 Sustainable Development Goals
Orbital and Physical Properties of the σ Ori Aa, Ab, B Triple System

We provide a complete characterization of the astrophysical properties of the σ Ori Aa, Ab, B hierarchical triple system and an improved set of orbital parameters for the highly eccentric σ Ori Aa, Ab spectroscopic binary. We compiled a spectroscopic data set comprising 90 high-resolution spectra covering a total time span of 1963 days. We applied the Lehman-Filhés method for a detailed orbital analysis of the radial velocity curves and performed a combined quantitative spectroscopic analysis of the σ Ori Aa, Ab, B system by means of the stellar atmosphere code FASTWIND. We used our own plus other available information on photometry and distance to the system for measuring the radii, luminosities, and spectroscopic masses of the three components. We also inferred evolutionary masses and stellar ages using the Bayesian code BONNSAI. The orbital analysis of the new radial velocity curves led to a very accurate orbital solution of the σ Ori Aa, Ab pair. We provided indirect arguments indicating that σ Ori B is a fast-rotating early B dwarf. The FASTWIND+BONNSAI analysis showed that the Aa, Ab pair contains the hottest and most massive components of the triple system while σ Ori B is a bit cooler and less massive. The derived stellar ages of the inner pair are intriguingly younger than the one widely accepted for the σ Orionis cluster, at 3 ± 1 Ma. The outcome of this study will be of key importance for a precise determination of the distance to the σ Orionis cluster, the interpretation of the strong X-ray emission detected for σ Ori Aa, Ab, B, and the investigation of the formation and evolution of multiple massive stellar systems and substellar objects.Financial support was provided by the Spanish Ministerio de Ciencia e Innovación and Ministerio de Economía y Competitividad under grants AYA2010-17631, AYA2010-15081, AYA2010-21697-C05-04, AYA2011-30147-C03-03, AYA2012-39364-C02-01/02, and Severo Ochoa SEV-2011-0187, and by the Canary Islands Government under grant PID2010119.

Heavy flavour decay muon production at forward rapidity in proton–proton collisions at √s = 7 TeV

The production of muons from heavy flavour decays is measured at forward rapidity in proton–proton collisions at √s = 7 TeV collected with the ALICE experiment at the LHC. The analysis is carried out on a data sample corresponding to an integrated luminosity Lint = 16.5 nb^−1. The transverse momentum and rapidity differential production cross sections of muons from heavy flavour decays are measured in the rapidity range 2.5 &lt; y &lt; 4, over the transverse momentum range 2 &lt; pt &lt; 12 GeV/c. The results are compared to predictions based on perturbative QCD calculations
Characters of the W 3 algebra

Traces of powers of the zero mode in the W 3 Algebra have recently been found to be of interest, for example in relation to Black Hole thermodynamics, and arise as the terms in an expansion of the full characters of the algebra. We calculate the first few such powers in two cases. Firstly, we find the traces in the 3-state Potts model by using null vectors to derive modular differential equations for the traces. Secondly, we calculate the exact results for Verma module representations. We compare our two methods with each other and the result of brute-force diagonalisation for low levels and find complete agreement
Invariant approach to CP in unbroken Δ(27)

The invariant approach is a powerful method for studying CP violation for specific Lagrangians. The method is particularly useful for dealing with discrete family symmetries. We focus on the CP properties of unbroken Δ(27) invariant Lagrangians with Yukawa-like terms, which proves to be a rich framework, with distinct aspects of CP , making it an ideal group to investigate with the invariant approach. We classify Lagrangians depending on the number of fields transforming as irreducible triplet representations of Δ(27) . For each case, we construct CP -odd weak basis invariants and use them to discuss the respective CP properties. We find that CP violation is sensitive to the number and type of Δ(27) representations
Paying people to eat or not to eat?: carryover effects of monetary incentives on eating behaviour

There is no evidence comparing head-to-head the effects of monetary incentives to act and to abstain from acting on behaviour. We present an experiment, conducted between June and September 2012, that directly compares the effects of those two different monetary incentive schemes on eating behaviour: we evaluate incentives to eat against incentives not to eat. A large number of participants (n = 353) had bowls of sweets next to them while they watched different videos over two experimental sessions that were two days apart. Sweets eating was monitored and monetary incentives to eat or not to eat were introduced during one of the videos for participants randomly allocated to these conditions. Our results show that, while both types of incentives were effective in changing sweets-eating behaviour when they were in place, only incentives not to eat had significant carryover effects after they were removed. Those effects were still significant two days after the monetary incentives had been eliminated. We also present some additional results on personality and health-related variables that shed further light on these effects. Overall, our study shows that incentives not to eat can be more effective in producing carryover effects on behaviour in domains like the one explored here
Taxas de suicídio e tendências em São Paulo, Brasil, de acordo com gênero, faixa etária e aspectos demográficos

OBJECTIVE: To evaluate suicide rates and trends in São Paulo by sex, age-strata, and methods. METHODS: Data was collected from State registry from 1996 to 2009. Population was estimated using the National Census. We utilized joinpoint regression analysis to explore temporal trends. We also evaluated marital status, ethnicity, birthplace and methods for suicide. RESULTS: In the period analyzed, 6,002 suicides were accrued with a rate of 4.6 per 100,000 (7.5 in men and 2.0 in women); the male-to-female ratio was around 3.7. Trends for men presented a significant decline of 5.3% per year from 1996 to 2002, and a significant increase of 2.5% from 2002 onwards. Women did not present significant changes. For men, the elderly (> 65 years) had a significant reduction of 2.3% per year, while younger men (25-44 years) presented a significant increase of 8.6% from 2004 onwards. Women did not present significant trend changes according to age. Leading suicide methods were hanging and poisoning for men and women, respectively. Other analyses showed an increased suicide risk ratio for singles and foreigners. CONCLUSIONS: Specific epidemiological trends for suicide in the city of São Paulo that warrant further investigation were identified. High-risk groups - such as immigrants - could benefit from targeted strategies of suicide prevention
Bicycle use for transport in an Australian and a Belgian city: Associations with built-environment attributes

The walkability attributes of neighborhood environments (residential density, land use mixture, and connectedness of streets) have been found to be associated with higher rates of walking. However, relatively less is known about the associations of walkability attributes with bicycle use for transport. We examined the relationships between adults' bicycle use for transport and measures of neighborhood walkability in two settings: an Australian city (Adelaide) with low rates of bicycle use and a Belgian city (Ghent) with high rates of bicycle use. A total of 2,159 and 382 participants were recruited in Adelaide and Ghent, respectively. A walkability index was derived from objectively measured data in Adelaide, while a similar index was derived from perceived measures in Ghent. Logistic regression models were employed to examine associations of bicycle use with different levels of walkability. There were higher rates of bicycle ownership for Ghent compared to Adelaide participants (96% versus 61%), and there was a higher prevalence of bicycle use for transport for Ghent compared to Adelaide participants (50% vs. 14%). Despite the large differences in bicycle ownership and use, living in a high-walkable neighborhood was associated with significantly higher odds of bicycle use for transport in both cities, after adjusting for relevant confounding factors. Built-environment innovations that are increasingly being advocated by health authorities and transport planners, primarily to promote higher rates ofwalking for transport, should also impact positively on bicycle use. © 2010 The New York Academy of Medicine.published_or_final_versionSpringer Open Choice, 01 Dec 201
