Super-renormalizable or Finite Lee-Wick Quantum Gravity

We propose a class of multidimensional higher derivative theories of gravity
without extra real degrees of freedom besides the graviton field. The
propagator shows up the usual real graviton pole and extra complex conjugates
poles that do not contribute to the absorptive part of the physical scattering
amplitudes. Indeed, they may consistently be excluded from the asymptotic
observable states of the theory making use of the Lee-Wick and Cutkoski,
Landshoff, Olive and Polkinghorne prescription for the construction of a
unitary S-matrix. Therefore, the spectrum consists on the graviton and short
lived elementary unstable particles that we named "anti-gravitons" because of
their repulsive contribution to the gravitational potential at short distance.
However, another interpretation of the complex conjugate pairs is proposed
based on the Calmet's suggestion, i.e. they could be understood as black hole
precursors long established in the classical theory. Since the theory is CPT
invariant, the complex conjugate of the micro black hole precursor has received
as a white hole precursor consistently with the t'Hooft complementary
principle. It is proved that the quantum theory is super-renormalizable in even
dimension, i.e. only a finite number of divergent diagrams survive, and finite
in odd dimension. Furthermore, turning on a local potential of the Riemann
tensor we can make the theory finite in any dimension. The singularity-free
Newtonian gravitational potential is explicitly computed for a range of higher
derivative theories. Finally, we propose a new super-reneromalizable or finite
Lee-Wick standard model of particle physics.Comment: LaTeX, 12 page
Clustering high dimensional mixed data to uncover sub-phenotypes:joint
  analysis of phenotypic and genotypic data

The LIPGENE-SU.VI.MAX study, like many others, recorded high dimensional
continuous phenotypic data and categorical genotypic data. LIPGENE-SU.VI.MAX
focuses on the need to account for both phenotypic and genetic factors when
studying the metabolic syndrome (MetS), a complex disorder that can lead to
higher risk of type 2 diabetes and cardiovascular disease. Interest lies in
clustering the LIPGENE-SU.VI.MAX participants into homogeneous groups or
sub-phenotypes, by jointly considering their phenotypic and genotypic data, and
in determining which variables are discriminatory.
  A novel latent variable model which elegantly accommodates high dimensional,
mixed data is developed to cluster LIPGENE-SU.VI.MAX participants using a
Bayesian finite mixture model. A computationally efficient variable selection
algorithm is incorporated, estimation is via a Gibbs sampling algorithm and an
approximate BIC-MCMC criterion is developed to select the optimal model.
  Two clusters or sub-phenotypes (`healthy' and `at risk') are uncovered. A
small subset of variables is deemed discriminatory which notably includes
phenotypic and genotypic variables, highlighting the need to jointly consider
both factors. Further, seven years after the LIPGENE-SU.VI.MAX data were
collected, participants underwent further analysis to diagnose presence or
absence of the MetS. The two uncovered sub-phenotypes strongly correspond to
the seven year follow up disease classification, highlighting the role of
phenotypic and genotypic factors in the MetS, and emphasising the potential
utility of the clustering approach in early screening. Additionally, the
ability of the proposed approach to define the uncertainty in sub-phenotype
membership at the participant level is synonymous with the concepts of
precision medicine and nutrition.Comment: 36 pages, 5 figures and 4 table
Working with cancer: Health and employment among cancer survivors

This is the author accepted manuscript. The final version is available from the publisher via the DOI in this record.Purpose: Cancer affects a growing proportion of US workers. Factors contributing to whether they continue or return to work after cancer diagnosis include: age, physical and mental health, health insurance, education, and cancer site. The purpose of this study was to assess the complex relationships between health indicators and employment status for adult cancer survivors. Methods: We analyzed pooled data from the 1997-2012 US National Health Interview Survey (NHIS). Our sample included adults with a self-reported physician diagnosis of cancer (n = 24,810) and adults with no cancer history (n = 382,837). Using structural equation modeling (SEM), we evaluated the relationship between sociodemographic factors, cancer site, and physical and mental health indicators on the overall health and employment status among adults with a cancer history. Results: The overall model for cancer survivors fit the data well (χ2 (374) = 3654.7, P < .001; comparative fit index = 0.98; root mean square error of approximation = 0.04). Although black cancer survivors were less likely to report good-to-excellent health, along with Hispanic survivors, they were more likely to continue to work after diagnosis compared with their white counterparts. Health insurance status and educational level were strongly and positively associated with health status and current employment. Age and time since diagnosis were not significantly associated with health status or employment, but there were significant differences by cancer site. Conclusions: A proportion of cancer survivors may continue to work because of employment-based health insurance despite reporting poor health and significant physical and mental health limitations. Acute and long-term health and social support are essential for the continued productive employment and quality of life of all cancer survivors.The work was supported in part by a National Cancer Institute (NCI) fellowship at the National Institutes of Health (1F31CA153937); the National Institute for Occupational Safety and Health (NIOSH R01 OH03915); and the European Regional Development Fund Programme and European Social Fund Convergence Programme for Cornwall and the Isles of Scilly (the University of Exeter Medical School)
Electric/magnetic duality and RG flows in AdS4/CFT3

A large set of relevant deformations of the ABJM field theory defined on a stack of M2 branes is captured holographically by D = 4 N = 8 SO(8)-gauged supergravity, which has accordingly been applied to study renormalisation group (RG) flows of the field theory between distinct superconformal phases. Recently, it has been discovered that this supergravity is not unique, and that a one-parameter family of gaugings of maximal supergravity exists. The parameter is an angle that measures the mixture of electric and magnetic vectors that gauge SO(8) dyonically. We construct and comprehensively characterise all domain walls between the critical points of the new supergravities with at least SU(3) invariance, which are expected to be dual to RG flows of new field theories defined at least at large N. We also construct some walls running off to infinity in scalar space, which we expect to be dual to Coulomb branch flows of these field theories
Fracture and debonding of a thin film on a stiff substrate: analytical and numerical solutions of a one-dimensional variational model

International audienceWestudymulti-fissurationanddebondingphenomenaofathinfilmbondedtoastiffsubstrateusing the variational approach to fracture mechanics. We consider a reduced one-dimensional membrane model where the loading is introduced through uniform inelastic (e.g., thermal) strains in the film or imposed dis- placements of the substrate. Fracture phenomena are accounted for by adopting a Griffith model for debonding and transverse fracture. On the basis of energy minimization arguments, we recover the key qualitative prop- erties of the experimental evidences, like the periodicity of transverse cracks and the peripheral debonding of each regular segment. Phase diagrams relate the maximum number of transverse cracks that may be created before debonding takes place, as a function of the material properties and the sample's geometry. The theo- retical results are illustrated with numerical simulations obtained through a finite element discretization and a regularized variational formulation of the Ambrosio-Tortorelli type, which is suited to further extensions in two-dimensional settings
The watering of tall trees  - Embolization and  recovery
 : 
Crude sap ascent and tree recovery

Extended introduction  and additive comments removed from the Journal of Theoretical Biology.22 pagesInternational audienceWe can propound a thermo-mechanical understanding of the ascent of sap to the top of tall trees thanks to a comparison between experiments associated with the cohesion-tension theory and the disjoining pressure concept for liquid thin-films. When a segment of xylem is tight-filled with crude sap, the liquid pressure can be negative although the pressure in embolized vessels remains positive.   Examples are given that illustrate how embolized vessels can be refilled and why the ascent of sap is possible even in the tallest trees avoiding the problem due to cavitation. However, the  maximum height of trees is  limited by the stability domain of liquid thin-films
The CHESS spectral survey of star forming regions: Peering into the protostellar shock L1157-B1. II. Shock dynamics

International audienceContext. The outflow driven by the low-mass class 0 protostar L1157 is the prototype of the so-called chemically active outflows. The bright bowshock B1 in the southern outflow lobe is a privileged testbed of magneto-hydrodynamical (MHD) shock models, for which dynamical and chemical processes are strongly interdependent. Aims: We present the first results of the unbiased spectral survey of the L1157-B1 bowshock, obtained in the framework of the key program “Chemical HErschel Surveys of star forming regions” (CHESS). The main aim is to trace the warm and chemically enriched gas and to infer the excitation conditions in the shock region. Methods: The CO 5-4 and o-H2O 110-101 lines have been detected at high-spectral resolution in the unbiased spectral survey of the HIFI-band 1b spectral window (555-636 GHz), presented by Codella et al. in this volume. Complementary ground-based observations in the submm window help establish the origin of the emission detected in the main-beam of HIFI and the physical conditions in the shock. Results: Both lines exhibit broad wings, which extend to velocities much higher than reported up to now. We find that the molecular emission arises from two regions with distinct physical conditions : an extended, warm (100 K), dense (3 × 105 cm-3) component at low-velocity, which dominates the water line flux in Band 1; a secondary component in a small region of B1 (a few arcsec) associated with high-velocity, hot (>400 K) gas of moderate density ((1.0-3.0) × 104 cm-3), which appears to dominate the flux of the water line at 179μm observed with PACS. The water abundance is enhanced by two orders of magnitude between the low- and the high-velocity component, from 8 × 10-7 up to 8 × 10-5. The properties of the high-velocity component agree well with the predictions of steady-state C-shock models.

A filtration of the modularrepresentation functor

Cataloged from PDF version of article.Let F and K be algebraically closed fields of characteristics p > 0 and 0, respectively. For any finite group G we denote by K RF (G) = K ⊗Z G0 (F G) the modular representation algebra of G over K where G0 (F G) is the Grothendieck group of finitely generated F G-modules with respect to exact sequences. The usual operations induction, inflation, restriction, and transport of structure with a group isomorphism between the finitely generated modules of group algebras over F induce maps between modular representation algebras making K RF an inflation functor. We show that the composition factors of K RF are precisely the simple inflation functors SC, Vi where C ranges over all nonisomorphic cyclic p′-groups and V ranges over all nonisomorphic simple K Out (C)-modules. Moreover each composition factor has multiplicity 1. We also give a filtration of K RF. © 2007 Elsevier Inc. All rights reserved
Airway inflammation in patients affected by obstructive sleep apnea syndrome.

Obstructive sleep apnea syndrome (OSAS) has been shown to be associated to upper airway inflammation. The object of the present study was to establish the presence of bronchial inflammation in OSAS subjects.\ud
In 16 subjects affected by OSAS, and in 14 healthy volunteers, airway inflammation was detected by the cellular analysis of the induced sputum.\ud
OSAS patients, as compared to control subjects, showed a higher percentage of neutrophils (66.7±18.9 vs. 25.8±15.6) (P<0.001) and a lower percentage of macrophages (29.4±18.4 vs. 70.8±15.3) (P<0.001). The percentage of eosinophils and lymphocytes were not significantly different in the two groups.\ud
OSAS subjects show bronchial inflammation characterized by a significant increase in neutrophils
Search for physics beyond the standard model in dilepton mass spectra in proton-proton collisions at sqrt(s) = 8 TeV

Dimuon and dielectron mass spectra, obtained from data resulting from proton-proton collisions at 8 TeV and recorded by the CMS experiment, are used to search for both narrow resonances and broad deviations from standard model predictions. The data correspond to an integrated luminosity of 20.6 (19.7) fb−1 for the dimuon (dielectron) channel. No evidence for non-standard-model physics is observed and 95% confidence level limits are set on parameters from a number of new physics models. The narrow resonance analyses exclude a Sequential Standard Model Z SSM ′ resonance lighter than 2.90 TeV, a superstring-inspired Z ψ ′ lighter than 2.57 TeV, and Randall-Sundrum Kaluza-Klein gravitons with masses below 2.73, 2.35, and 1.27 TeV for couplings of 0.10, 0.05, and 0.01, respectively. A notable feature is that the limits have been calculated in a model-independent way to enable straightforward reinterpretation in any model predicting a resonance structure. The observed events are also interpreted within the framework of two non-resonant analyses: one based on a large extra dimensions model and one based on a quark and lepton compositeness model with a left-left isoscalar contact interaction. Lower limits are established on MS, the scale characterizing the onset of quantum gravity, which range from 4.9 to 3.3 TeV, where the number of additional spatial dimensions varies from 3 to 7. Similarly, lower limits on Λ, the energy scale parameter for the contact interaction, are found to be 12.0 (15.2) TeV for destructive (constructive) interference in the dimuon channel and 13.5 (18.3) TeV in the dielectron channel
Indirect controllability of some linear parabolic systems of m equations with m − 1 controls involving coupling terms of zero or first order

International audienceThis paper is devoted to the study of the null and approximate controllability for some classes of linear coupled parabolic systems with less controls than equations. More precisely, for a given bounded domain Ω in R N (N ∈ N *), we consider a system of m linear parabolic equations (m 2) with coupling terms of first and zero order, and m − 1 controls localized in some arbitrary nonempty open subset ω of Ω. In the case of constant coupling coefficients, we provide a necessary and sufficient condition to obtain the null or approximate controllability in arbitrary small time. In the case m = 2 and N = 1, we also give a generic sufficient condition to obtain the null or approximate controllability in arbitrary small time for general coefficients depending on the space and times variables, provided that the supports of the coupling terms intersect the control domain ω. The results are obtained thanks to the fictitious control method together with an algebraic method and some appropriate Carleman estimates
High-level expression of Aspergillus niger β-galactosidase in Ashbya gossypii

Ashbya gossypii has been recently considered as a host for the expression of recombinant proteins. The production levels achieved thus far were similar to those obtained with Saccharomyces cerevisiae for the same proteins. Here, the β-galactosidase from Aspergillus niger was successfully expressed and secreted by A. gossypii from 2-micron plasmids carrying the native signal sequence at higher levels than those secreted by S. cerevisiae laboratorial strains. Four different constitutive promoters were used to regulate the expression of β-galactosidase: A. gossypii AgTEF and AgGPD promoters, and S. cerevisiae ScADH1 and ScPGK1 promoters. The native AgTEF promoter drove the highest expression levels of recombinant β-galactosidase in A. gossypii, leading to 2- and 8-fold higher extracellular activity than the AgGPD promoter and the heterologous promoters, respectively. In similar production conditions, the levels of active β-galactosidase secreted by A. gossypii were up to 37 times higher than those secreted by recombinant S. cerevisiae and approximately 2.5 times higher than those previously reported for the β-galactosidase-high producing S. cerevisiae NCYC869-A3/pVK1.1. The substitution of glucose by glycerol in the production medium led to a 1.5-fold increase in the secretion of active β-galactosidase by A. gossypii. Recombinant β-galactosidase secreted by A. gossypii was extensively glycosylated, as are the native A. niger β-galactosidase and recombinant β-galactosidase produced by yeast. These results highlight the potential of A. gossypii as a recombinant protein producer and open new perspectives to further optimize recombinant protein secretion in this fungus.Project AshByofactory (grant PTDC/EBB-EBI/101985/2008 - FCOMP-01-0124-FEDER-009701), MIT-Portugal Program (PhD grant SFRH/BD/39112/2007 to Tatiana Q.

Herschel-ATLAS : the dust energy balance in the edge-on spiral galaxy UGC 754

We use Herschel PACS and SPIRE observations of the edge-on spiral galaxy UGC 4754, taken as part of the H-ATLAS SDP observations, to investigate the dust energy balance in this galaxy. We build detailed SKIRT radiative models based on SDSS and UKIDSS maps and use these models to predict the far-infrared emission. We find that our radiative transfer model underestimates the observed FIR emission by a factor of two to three. Similar discrepancies have been found for other edge-on spiral galaxies based on IRAS, ISO, and SCUBA data. Thanks to the good sampling of the SED at FIR wavelengths, we can rule out an underestimation of the FIR emissivity as the cause for this discrepancy. Instead we support highly obscured star formation that contributes little to the optical extinction as a more probable explanation
Negative mood reverses devaluation of goal-directed drug-seeking favouring an incentive learning account of drug dependence.

Background Two theories explain how negative mood primes smoking behaviour. The stimulus?response (S-R) account argues that in the negative mood state, smoking is experienced as more reinforcing, establishing a direct (automatic) association between the negative mood state and smoking behaviour. By contrast, the incentive learning account argues that in the negative mood state smoking is expected to be more reinforcing, which integrates with instrumental knowledge of the response required to produce that outcome. Objectives One differential prediction is that whereas the incentive learning account anticipates that negative mood induction could augment a novel tobacco-seeking response in an extinction test, the S-R account could not explain this effect because the extinction test prevents S-R learning by omitting experience of the reinforcer. Methods To test this, overnight-deprived daily smokers (n?=?44) acquired two instrumental responses for tobacco and chocolate points, respectively, before smoking to satiety. Half then received negative mood induction to raise the expected value of tobacco, opposing satiety, whilst the remainder received positive mood induction. Finally, a choice between tobacco and chocolate was measured in extinction to test whether negative mood could augment tobacco choice, opposing satiety, in the absence of direct experience of tobacco reinforcement. Results Negative mood induction not only abolished the devaluation of tobacco choice, but participants with a significant increase in negative mood increased their tobacco choice in extinction, despite satiety. Conclusions These findings suggest that negative mood augments drug-seeking by raising the expected value of the drug through incentive learning, rather than through automatic S-R control.publishersversionPeer reviewe
The VIMOS Public Extragalactic Redshift Survey (VIPERS): Downsizing of
  the blue cloud and the influence of galaxy size on mass quenching over the
  last eight billion years

We use the full VIPERS redshift survey in combination with SDSS-DR7 to
explore the relationships between star-formation history (using d4000), stellar
mass and galaxy structure, and how these relationships have evolved since z~1.
We trace the extents and evolutions of both the blue cloud and red sequence, by
fitting double Gaussians to the d4000 distribution of galaxies in narrow
stellar mass bins, for four redshift intervals over 0<z<1. This reveals
downsizing in star formation, as the high-mass limit of the blue cloud retreats
steadily with time from M*~10^11.2 M_sun at z~0.9 to M*~10^10.7 M_sun by the
present day. The number density of massive blue-cloud galaxies (M*>10^11 M_sun,
d4000<1.55) drops sharply by a factor five between z~0.8 and z~0.5. These
galaxies are becoming quiescent at a rate that largely matches the increase in
the numbers of massive passive galaxies seen over this period. We examine the
size-mass relation of blue cloud galaxies, finding that its high-mass boundary
runs along lines of constant M*/r_e or equivalently inferred velocity
dispersion. Larger galaxies can continue to form stars to higher stellar masses
than smaller galaxies. As blue cloud galaxies approach this high-mass limit,
they start to be quenched, their d4000 values increasing to push them towards
the green valley. In parallel, their structures change, showing higher Sersic
indices and central stellar mass densities. For these galaxies, bulge growth is
necessary for them to reach the high-mass limit of the blue cloud and be
quenched by internal mechanisms. The blue cloud galaxies that are being
quenched at z~0.8 lie along the same size-mass relation as present day
quiescent galaxies, and seem the likely progenitors of today's S0s.Comment: 20 pages, 15 figures. Submitted to A&A. References updated. Comments

Aspects of Berry phase in QFT

When continuous parameters in a QFT are varied adiabatically, quantum states
typically undergo mixing---a phenomenon characterized by the Berry phase. We
initiate a systematic analysis of the Berry phase in QFT using standard quantum
mechanics methods. We show that a non-trivial Berry phase appears in many
familiar QFTs. We study a variety of examples including free electromagnetism
with a theta angle, and certain supersymmetric QFTs in two and four spacetime
dimensions. We also argue that a large class of QFTs with rich Berry properties
is provided by CFTs with non-trivial conformal manifolds. Using the
operator-state correspondence we demonstrate in this case that the Berry
connection is equivalent to the connection on the conformal manifold derived
previously in conformal perturbation theory. In the special case of chiral
primary states in 2d N=(2,2) and 4d N=2 SCFTs the Berry phase is governed by
the tt* equations. We present a technically useful rederivation of these
equations using quantum mechanics methods.Comment: 50 pages; v2 typos corrected, published versio
