Finite-size effects in the spectrum of the OSp(3|2) superspin chain

The low energy spectrum of a spin chain with OSp(3|2) supergroup symmetry is studied based on the Bethe ansatz solution of the related vertex model. This model is a lattice realization of intersecting loops in two dimensions with loop fugacity z=1 which provides a framework to study the critical properties of the unusual low temperature Goldstone phase of the O(N) sigma model for N=1 in the context of an integrable model. Our finite-size analysis provides strong evidence for the existence of continua of scaling dimensions, the lowest of them starting at the ground state. Based on our data we conjecture that the so-called watermelon correlation functions decay logarithmically with exponents related to the quadratic Casimir operator of OSp(3|2) . The presence of a continuous spectrum is not affected by a change to the boundary conditions although the density of states in the continua appears to be modified
Generalised integrable λ - and η -deformations and their relation

We construct two-parameter families of integrable λ -deformations of two-dimensional field theories. These interpolate between a CFT (a WZW/gauged WZW model) and the non-Abelian T-dual of a principal chiral model on a group/symmetric coset space. In examples based on the SU(2) WZW model and the SU(2)/U(1) exact coset CFT, we show that these deformations are related to bi-Yang–Baxter generalisations of η -deformations via Poisson–Lie T-duality and analytic continuation. We illustrate the quantum behaviour of our models under RG flow. As a byproduct we demonstrate that the bi-Yang–Baxter σ -model for a general group is one-loop renormalisable
Observations of the Blazar 3C 66A with the MAGIC Telescopes in
  Stereoscopic Mode

We report new observations of the intermediate-frequency peaked BL Lacertae
object 3C 66A with the MAGIC telescopes. The data sample we use were taken in
2009 December and 2010 January, and comprises 2.3 hr of good quality data in
stereoscopic mode. In this period, we find a significant signal from the
direction of the blazar 3C 66A. The new MAGIC stereoscopic system is shown to
play an essential role for the separation between 3C 66A and the nearby radio
galaxy 3C 66B, which is at a distance of only $6^\prime$. The derived integral
flux above $100\eh{GeV}$ is 8.3% of Crab Nebula flux and the energy spectrum is
reproduced by a power law of photon index $3.64 \pm 0.39_{\rm stat} \pm
0.25_{\rm sys}$. Within errors, this is compatible with the one derived by
VERITAS in 2009. From the spectra corrected for absorption by the extragalactic
background light, we only find small differences between the four models that
we applied, and constrain the redshift of the blazar to $z < 0.68$
Public Health, Policy Analysis, Risk Assessment,and Impact Assessment

Public health has been defined as "the science and art of preventing disease, prolonging life and promoting health through the organized efforts and informed choices of society, organizations, public and private, communities and individuals"(Winslow 1920) or as "the art of applying science in the context of politics so as to reduce inequalities in health while ensuring the best health for the greatest number"(WHO1998). As the challenges of public health have evolved, from sanitary surveillance and infectious diseases in the past, to chronic diseases, lifestyle factors,socioeconomic conditions, occupational and environmental health determinants,health reforms and others, so have the methods of assessment advanced by research technologies development. The new health threats and epidemics, such as AIDS, SARS (Severe Acute Respiratory Syndrome), influenza H5N1, or emergencies like natural disasters or bioterrorism, effects of globalization and migration present new tasks to public health governance requiring new working methods.
Oligomerization-function relationship of EGFR on living cells detected by the coiled-coil labeling and FRET microscopy.

The epidermal growth factor receptor (EGFR) is a well-studied receptor tyrosine kinase and an important anticancer therapeutic target. The activity of EGFR autophosphorylation and transphosphorylation, which induces several cell signaling pathways, has been suggested to be related to its oligomeric state. However, the oligomeric states of EGFRs induced by EGF binding and the receptor-ligand stoichiometry required for its activation are still controversial. In the present study, we performed Förster resonance energy transfer (FRET) measurements by combining the coiled-coil tag-probe labeling method and spectral imaging to quantitatively analyze EGFR oligomerization on living CHO-K1 cell membranes at physiological expression levels. In the absence of its ligands, EGFRs mainly existed as monomers with a small fraction of predimers (~10%), whereas ~70% of the EGFRs formed dimers after being stimulated with the ligand EGF. Ligand-induced dimerization was not significantly affected by the perturbation of membrane components (cholesterol or monosialoganglioside GM3). We also investigated both dose and time dependences of EGF-dependent EGFR dimerization and autophosphorylation. The formation of dimers occurred within 20s of the ligand stimulation and preceded its autophosphorylation, which reached a plateau 90s after the stimulation. The EGF concentration needed to evoke half-maximum dimerization (~1nM) was lower than that for half-maximum autophosphorylation (~8nM), which suggested the presence of an inactive dimer binding a single EGF molecule
Justice and conservation: The need to incorporate recognition

In light of the Aichi target to manage protected areas equitably by 2020, we ask how the conservation sector should define justice. We focus in particular on ‘recognition’, because it is the least well understood aspect of environmental justice, and yet highly relevant to conservation because of its concern with respect for local knowledge and cultures. In order to explore the meaning of recognition in the conservation context, we take four main steps. First, we identify four components of recognition to serve as our analytical framework: subjects of justice, the harms that constitute injustice, the mechanisms that produce injustices, and the responses to alleviate these. Secondly, we apply this framework to explore four traditions of thinking about recognition: Hegelian inter-subjectivity, critical theory, southern decolonial theory, and the capabilities approach. Thirdly, we provide three case studies of conservation conflicts highlighting how different theoretical perspectives are illustrated in the claims and practices of real world conservation struggles. Fourthly, we finish the paper by drawing out some key differences between traditions of thinking, but also important areas of convergence. The convergences provide a basis for concluding that conservation should look beyond a distributive model of justice to incorporate concerns for social recognition, including careful attention to ways to pursue equality of status for local conservation stakeholders. This will require reflection on working practices and looking at forms of intercultural engagement that, for example, respect alternative ways of relating to nature and biodiversity
Testing the new CP phase in a supersymmetric model with Q(6) family symmetry by B(s) mixing. \ud

The new contribution to the non-diagonal matrix element M12 of the neutral Bs meson system is investigated in a supersymmetric extension of the standard model based on the discrete Q6 family symmetry. We assume that CP is explicitly, but softly broken only by the b   terms in the soft supersymmetry breaking sector. We find that the new contributions to M12 are real, and that nevertheless there exists an observable difference in the CP phase compared with the standard model. We focus our attention on the flavor-specific CP asymmetry View the MathML source, and find that View the MathML source of the model is mostly negative and its size can be one order of magnitude larger the standard model value. This prediction is consistent with the current experimental value, and might be experimentally tested in future
Convex hulls of random walks and their scaling limits.

For the perimeter length and the area of the convex hull of the first n steps of a planar random walk, we study n→∞ mean and variance asymptotics and establish non-Gaussian distributional limits. Our results apply to random walks with drift (for the area) and walks with no drift (for both area and perimeter length) under mild moments assumptions on the increments. These results complement and contrast with previous work which showed that the perimeter length in the case with drift satisfies a central limit theorem. We deduce these results from weak convergence statements for the convex hulls of random walks to scaling limits defined in terms of convex hulls of certain Brownian motions. We give bounds that confirm that the limiting variances in our results are non-zero
Comparative Study of Polar and Semipolar (11 22) InGaN layers Grown by Metalorganic Vapour Phase Epitaxy

InGaN layers were grown simultaneously on (11¯22) GaN and (0001) GaN templates by metalorganic vapour phase epitaxy.
At higher growth temperature ( 750oC), the indium content (<15%) of the (11¯22) and (0001) InGaN layers was
similar. However, for temperatures less than 750oC, the indium content of the (11¯22) InGaN layers (15 - 26%) was generally
lower than those with (0001) orientation (15 - 32%). The compositional deviation was attributed to the different
strain relaxations between the (11¯22) and (0001) InGaN layers. Room temperature photoluminescence measurements
of the (11¯22) InGaN layers showed an emission wavelength that shifts gradually from 380 nm to 580 nm with decreasing
growth temperature (or increasing indium composition). The peak emission wavelength of the (11 ¯22) InGaN layers
with an indium content of more than 10% blue-shifted a constant value of  (50 - 60) nm when using higher excitation
power densities. This blue-shift was attributed to band  lling effects in the layers.This work was  nancially supported by the EU-FP7

Interventions for promoting participation in shared decision-making for children with cancer

Ways of helping children with cancer to take part in decisions about their health care Cancer is a serious illness that involves complex treatments with unpleasant side effects. Children with cancer generally prefer to be involved in some way in decisions about their care and treatment. Involving children in decisions about their health care can help their understanding of the disease and treatment, reduce their fears, help them feel more prepared and help them cope better with their cancer. The review of trials did not find any studies that helped children to participate in decision-making with parents and healthcare staff. More research is needed
Einstein-Maxwell-Anti-de-Sitter spinning solitons

Electrostatics on global Anti-de-Sitter (AdS) spacetime is sharply different
from that on global Minkowski spacetime. It admits a multipolar expansion with
everywhere regular, finite energy solutions, for every multipole moment except
the monopole (arXiv:1507.04370). A similar statement holds for global AdS
magnetostatics. We show that everywhere regular, finite energy, electric plus
magnetic fields exist on AdS in three distinct classes: $(I)$ with
non-vanishing total angular momentum $J$; $(II)$ with vanishing $J$ but
non-zero angular momentum density, $T^t_\varphi$; $(III)$ with vanishing $J$
and $T^t_\varphi$. Considering backreaction, these configurations remain
everywhere smooth and finite energy, and we find, for example,
Einstein-Maxwell-AdS solitons that are globally - Type I - or locally (but not
globally) - Type II - spinning. This backreaction is considered first
perturbatively, using analytical methods and then non-perturbatively, by
constructing numerical solutions of the fully non-linear Einstein-Maxwell-AdS
system. The variation of the energy and total angular momentum with the
boundary data is explicitly exhibited for one example of a spinning soliton.Comment: 15 pages, 3 figure
Measurement of the Z gamma to nu nu-bar gamma production cross section
  in pp collisions at sqrt(s) = 8 TeV and limits on anomalous Z-Z-gamma and
  Z-gamma-gamma trilinear gauge boson couplings

A measurement of the Z gamma to nu nu-bar gamma production cross section in
pp collisions at sqrt(s) = 8 TeV is presented, using data corresponding to an
integrated luminosity of 19.6 inverse femtobarns collected with the CMS
detector at the LHC. This measurement is based on the observation of events
with large missing energy and with a single photon with transverse momentum
above 145 GeV and absolute pseudorapidity in the range |eta| < 1.44. The
measured Z gamma to nu nu-bar gamma production cross section, 52.7 +/-
2.1(stat) +/- 6.4 (syst) +/- 1.4 (lumi) fb, agrees well with the standard model
prediction of 50.0 +2.4 -2.2 fb. A study of the photon transverse momentum
spectrum yields the most stringent limits to date on the anomalous Z-Z-gamma
and Z-gamma-gamma trilinear gauge boson couplings.Comment: Replaced with published version. Added the journal reference and DOI.

Mixed Heavy-Light Matching in the Universal One-Loop Effective Action

Recently, a general result for evaluating the path integral at one loop was
obtained in the form of the Universal One-Loop Effective Action. It may be used
to derive effective field theory operators of dimensions up to six, by
evaluating the traces of matrices in this expression, with the mass-dependence
encapsulated in the universal coefficients. Here we show that it can account
for loops of mixed heavy-light particles in the matching procedure. Our
prescription for computing these mixed contributions to the Wilson coefficients
is conceptually simple. Moreover it has the advantage of maintaining the
universal structure of the effective action, which we illustrate using the
example of integrating out a heavy electroweak triplet scalar coupling to a
light Higgs doublet. Finally we also identify new structures that were
previously neglected in the universal results.Comment: 22 pages, 3 figures; v2: expanded discussion in Section 3, typos

Helicity in Proton-Proton Elastic Scattering and the Spin Structure of
  the Pomeron

We discuss different models for the spin structure of the nonperturbative
pomeron: scalar, vector, and rank-2 symmetric tensor. The ratio of
single-helicity-flip to helicity-conserving amplitudes in polarised high-energy
proton-proton elastic scattering, known as the complex r_5 parameter, is
calculated for these models. We compare our results to experimental data from
the STAR experiment. We show that the spin-0 (scalar) pomeron model is clearly
excluded by the data, while the vector pomeron is inconsistent with the rules
of quantum field theory. The tensor pomeron is found to be perfectly consistent
with the STAR data.Comment: 14 page
Meta-analysis of genome-wide association studies for neuroticism, and the polygenic association with Major Depressive Disorder

Contains fulltext :
                  156183.pdf (publisher's version ) (Open Access)IMPORTANCE Neuroticism is a pervasive risk factor for psychiatric conditions. It genetically overlaps with major depressive disorder (MDD) and is therefore an important phenotype for psychiatric genetics. The Genetics of Personality Consortium has created a resource for genome-wide association analyses of personality traits in more than 63 000 participants (including MDD cases). OBJECTIVES To identify genetic variants associated with neuroticism by performing a meta-analysis of genome-wide association results based on 1000 Genomes imputation; to evaluate whether common genetic variants as assessed by single-nucleotide polymorphisms (SNPs) explain variation in neuroticism by estimating SNP-based heritability; and to examine whether SNPs that predict neuroticism also predict MDD. DESIGN, SETTING, AND PARTICIPANTS Genome-wide association meta-analysis of 30 cohorts with genome-wide genotype, personality, and MDD data from the Genetics of Personality Consortium. The study included 63 661 participants from 29 discovery cohorts and 9786 participants from a replication cohort. Participants came from Europe, the United States, or Australia. Analyses were conducted between 2012 and 2014. MAIN OUTCOMES AND MEASURES Neuroticism scores harmonized across all 29 discovery cohorts by item response theory analysis, and clinical MDD case-control status in 2 of the cohorts. RESULTS A genome-wide significant SNP was found on 3p14 in MAGI1 (rs35855737; P = 9.26 x 10(-9) in the discovery meta-analysis). This association was not replicated (P = .32), but the SNP was still genome-wide significant in the meta-analysis of all 30 cohorts (P = 2.38 x 10(-8)). Common genetic variants explain 15% of the variance in neuroticism. Polygenic scores based on the meta-analysis of neuroticism in 27 cohorts significantly predicted neuroticism (1.09 x 10(-12) < P < .05) and MDD (4.02 x 10(-9) < P < .05) in the 2 other cohorts. CONCLUSIONS AND RELEVANCE This study identifies a novel locus for neuroticism. The variant is located in a known gene that has been associated with bipolar disorder and schizophrenia in previous studies. In addition, the study shows that neuroticism is influenced by many genetic variants of small effect that are either common or tagged by common variants. These genetic variants also influence MDD. Future studies should confirm the role of the MAGI1 locus for neuroticism and further investigate the association of MAGI1 and the polygenic association to a range of other psychiatric disorders that are phenotypically correlated with neuroticism.9 p
How to match the optimal currently available inhaler device to an individual child with asthma or recurrent wheeze.

Contains fulltext :
                  156886.pdf (publisher's version ) (Open Access)Inhaled medications are the cornerstone of treatment in early childhood wheezing and paediatric asthma. A match between patient and device and a correct inhalation technique are crucial for good asthma control. The aim of this paper is to propose an inhaler strategy that will facilitate an inhaler choice most likely to benefit different groups of children. The main focus will be on pressurised metered dose inhalers and dry powder inhalers. In this paper we will discuss (1) practical difficulties with the devices and with inhaled therapy and (2) the optimal location for deposition of medicines in the lungs, and (3) we will propose a practical and easy way to make the best match between the inhaler device and the individual patient. We hope that this paper will contribute to an increased likelihood of treatment success and improved adherence to therapy
Incorporation of H_2 in vitreous silica, qualitative and quantitative determination from Raman and infrared spectroscopy

Incorporation mechanisms of H_2 in silica glass were studied with Raman and infrared (IR) microspectroscopy. Hydrogenated samples were prepared at temperatures between 800 deg C and 955 deg C at 2 kbar total pressure. Hydrogen fugacities (f_{H_2}) were controlled using the double capsule technique with the iron-w\"ustite (IW) buffer assemblage generating f_{H_2} of 1290-1370 bars corresponding to H_2 partial pressures (P_{H_2}) of 960-975 bars. We found that silica glass hydrogenated under such conditions contains molecular hydrogen (H_2) in addition to SiH and SiOH groups. H_2 molecules dissolved in the quenched glasses introduce a band at 4136 cm^{-1} in the Raman spectra which in comparison to that of gaseous H_2 is wider and is shifted to lower frequency. IR spectra of hydrogenated samples contain a band at 4138 cm^{-1} which we assign to the stretching vibration of H_2 molecules located in non-centrosymmetric sites. The Raman and IR spectra indicate that the dissolved H_2 molecules interact with the silicate network. We suggest that the H_2 band is the envelope of at least three components due to the occupation of at least three different interstitial sites by H_2 molecules. Both, Raman and IR spectra of hydrogenated glasses contain bands at ~2255 cm^{-1} which may be due to the vibration of SiH groups
Ideals generated by 2-minors, collection of cells and stack polyominoes

In this paper we study ideals generated by quite general sets of 2-minors of
an $m \times n$-matrix of indeterminates. The sets of 2-minors are defined by
collections of cells and include 2-sided ladders. For convex collections of
cells it is shown that the attached ideal of 2-minors is a Cohen--Macaulay
prime ideal. Primality is also shown for collections of cells whose connected
components are row or column convex. Finally the class group of the ring
attached to a stack polyomino and its canonical class is computed, and a
classification of the Gorenstein stack polyominoes is given.Comment: 29 pages, 32 figure
Hydrogen supersymmetry: A new method in perturbation theory

The O(4) supersymmetry of the hydrogen atom is utilized to construct a
complete basis using only the bound state wave functions. For a large class of
perturbations, an expansion of the electron (exciton) wave function into such a
complete set reduces the perturbed Schroedinger equation to a standard
eigenvalue problem with an equidistant unperturbed spectrum. A high-order
polarizability of the ground state of the hydrogen atom in a static electric
field is calculated via Rayleigh-Schroedinger perturbation theory for
illustration of the new method.Comment: 12 pages, 1 fugur
Reconstructing Plants in 3D from a Single Image Using Analysis-by-Synthesis

International audienceMature computer vision techniques allow the reconstruction of challenging 3D objects from images. However, due to high complexity of plant topology, dedicated methods for generating 3D plant models must be devised. We propose to generate a 3D model of a plant, using an analysis-by-synthesis method mixing information from a single image and a priori knowledge of the plant species. First, our dedicated skeletonisation algorithm generates a possible branch- ing structure from the foliage segmentation. Then, a 3D generative model, based on a parametric model of branching systems that takes into ac- count botanical knowledge is built. The resulting skeleton follows the hierarchical organisation of natural branching structures. An instance of a 3D model can be generated. Moreover, varying parameter values of the generative model (main branching structure of the plant and foliage), we produce a series of candidate models. The reconstruction is improved by selecting the model among these proposals based on a matching criterion with the image. Realistic results obtained on di erent species of plants illustrate the performance of the proposed method
