Kac-Moody algebras and Lie algebras of regular vector fields on tori

We consider the problem of representing the Kac-Moody algebra
$\mathfrak{g}(N)$ specified by an $r\times r$ indecomposable generalised Cartan
matrix $N$ as vector fields on the torus ${{\bb C}^*}^r$. It is shown that, if
the representations are of a certain form, this is possible if and only if
$\mathfrak{g}(N)\cong sl(r+1,{\bb C})$ or $\tilde{sl}(r,{\bb C})$. For
$sl(r+1,{\bb C})$ and $\tilde{sl}(r,{\bb C})$, discrete families of
representations are constructed. These generalise the well-known discrete
families of representations of $sl(2,{\bb C})$ as regular vector fields on
${\bb C}^*$Comment: 20 pages, typo corrected in the titl
A Morse complex for infinite dimensional manifolds - Part I

In this paper and in the forthcoming Part II we introduce a Morse complex for
a class of functions f defined on an infinite dimensional Hilbert manifold M,
possibly having critical points of infinite Morse index and coindex. The idea
is to consider an infinite dimensional subbundle - or more generally an
essential subbundle - of the tangent bundle of M, suitably related with the
gradient flow of f. This Part I deals with the following questions about the
intersection W of the unstable manifold of a critical point x and the stable
manifold of another critical point y: finite dimensionality of W, possibility
that different components of W have different dimension, orientatability of W
and coherence in the choice of an orientation, compactness of the closure of W,
classification, up to topological conjugacy, of the gradient flow on the
closure of W, in the case dim W=2.Comment: LaTeX2e file, 62 pages, to appear in Advances in Mathematics. Revised

The Renyi-Ulam pathological liar game with a fixed number of lies

The $q$-round Renyi-Ulam pathological liar game with $k$ lies on the set
$[n]:=\{1,...,n\}$ is a 2-player perfect information zero sum game. In each
round Paul chooses a subset $A\subseteq [n]$ and Carole either assigns 1 lie to
each element of $A$ or to each element of $[n]\setminus A$. Paul wins if after
$q$ rounds there is at least one element with $k$ or fewer lies. The game is
dual to the original Renyi-Ulam liar game for which the winning condition is
that at most one element has $k$ or fewer lies. We prove the existence of a
winning strategy for Paul to the existence of a covering of the discrete
hypercube with certain relaxed Hamming balls. Defining $F^*_k(q)$ to be the
minimum $n$ such that Paul can win the $q$-round pathological liar game with
$k$ lies and initial set $[n]$, we find $F^*_1(q)$ and $F^*_2(q)$ exactly. For
fixed $k$ we prove that $F_k^*(q)$ is within an absolute constant (depending
only on $k$) of the sphere bound, $2^q/\binom{q}{\leq k}$; this is already
known to hold for the original Renyi-Ulam liar game due to a result of J.

$SU(3)_{F}$ Gauge Family Model and New Symmetry Breaking Scale From FCNC
  Processes

Based on the $SU(3)_{F}$ gauge family symmetry model which was proposed to
explain the observed mass and mixing pattern of neutrinos, we investigate the
symmetry breaking, the mixing pattern in quark and lepton sectors, and the
contribution of the new gauge bosons to some flavour changing neutral currents
(FCNC) processes at low energy. With the current data of the mass differences
in the neutral pseudo-scalar $P^{0}-\bar{P}^{0}$ systems, we find that the
$SU(3)_{F}$ symmetry breaking scale can be as low as 300TeV and the mass of the
lightest gauge boson be about $100$TeV. Other FCNC processes, such as the
lepton flavour number violation process $\mu^{-}\rightarrow e^{-}e^{+}e^{-}$
and the semi-leptonic rare decay $K\rightarrow \pi \bar{\nu} \nu$, contain
contributions via the new gauge bosons exchanging. With the constrains got from
$P^0-\bar{P}^0$ system, we estimate that the contribution of the new physics is
around $10^{-16}$, far below the current experimental bounds.Comment: 3figure
Scheme dependence and Transverse Momentum Distribution interpretation of
  Collins-Soper-Sterman resummation

Following an earlier derivation by Catani-de Florian-Grazzini (2000) on the
scheme dependence in the Collins-Soper-Sterman (CSS) resummation formalism in
hard scattering processes, we investigate the scheme dependence of the
Transverse Momentum Distributions (TMDs) and their applications. By adopting a
universal $C$-coefficient function associated with the integrated parton
distributions, the difference between various TMD schemes can be attributed to
a perturbative calculable function depending on the hard momentum scale. We
further apply several TMD schemes to the Drell-Yan process of lepton pair
production in hadronic collisions, and find that the constrained
non-perturbative form factors in different schemes are remarkably consistent
with each other and with that of the standard CSS formalism.Comment: 10 pages, 2 figure

The proper motion, μ = 12.5 ± 1 mas yr-1, is one of the highest for microlensing planets yet discovered, implying that it will be possible to separately resolve the host within ∼7 yr. Two separate lines of evidence imply that the planet and host are in the Galactic disk. The planet could have been detected and characterized purely with follow-up data, which has important implications for microlensing surveys, both current and into the Large Synoptic Survey Telescope (LSST) era.Publisher PDFPeer reviewe
Effects of asymmetric questions on impression formation: A trade-off between evidence diagnosticity and frequency

When examining social targets, people may ask asymmetric questions, that is, questions for which “yes” and “no” answers are neither equally diagnostic nor equally frequent. The consequences of this information-gathering strategy on impression formation deserve empirical investigation. The present work explored the role played by the trade-off between the diagnosticity and frequency of answers that follow asymmetric questions. In Study 1, participants received answers to symmetric/asymmetric questions on an anonymous social target. In Study 2, participants read answers to a specific symmetric/asymmetric question provided by different group members. Overall, the results of both studies indicate that asymmetric questions had less impact on impressions than did symmetric questions, suggesting that individuals are more sensitive to data frequency than diagnosticity when forming impressions
Is there a common water-activity limit for the three domains of life?

Archaea and Bacteria constitute a majority of life systems on Earth but have long been considered inferior to Eukarya in terms of solute tolerance. Whereas the most halophilic prokaryotes are known for an ability to multiply at saturated NaCl (water activity (aw) 0.755) some xerophilic fungi can germinate, usually at high-sugar concentrations, at values as low as 0.650–0.605 aw. Here, we present evidence that halophilic prokayotes can grow down to water activities of <0.755 for Halanaerobium lacusrosei (0.748), Halobacterium strain 004.1 (0.728), Halobacterium sp. NRC-1 and Halococcus morrhuae (0.717), Haloquadratum walsbyi (0.709), Halococcus salifodinae (0.693), Halobacterium noricense (0.687), Natrinema pallidum (0.681) and haloarchaeal strains GN-2 and GN-5 (0.635 aw). Furthermore, extrapolation of growth curves (prone to giving conservative estimates) indicated theoretical minima down to 0.611 aw for extreme, obligately halophilic Archaea and Bacteria. These were compared with minima for the most solute-tolerant Bacteria in high-sugar (or other non-saline) media (Mycobacterium spp., Tetragenococcus halophilus, Saccharibacter floricola, Staphylococcus aureus and so on) and eukaryotic microbes in saline (Wallemia spp., Basipetospora halophila, Dunaliella spp. and so on) and high-sugar substrates (for example, Xeromyces bisporus, Zygosaccharomyces rouxii, Aspergillus and Eurotium spp.). We also manipulated the balance of chaotropic and kosmotropic stressors for the extreme, xerophilic fungi Aspergillus penicilloides and X. bisporus and, via this approach, their established water-activity limits for mycelial growth (~0.65) were reduced to 0.640. Furthermore, extrapolations indicated theoretical limits of 0.632 and 0.636 aw for A. penicilloides and X. bisporus, respectively. Collectively, these findings suggest that there is a common water-activity limit that is determined by physicochemical constraints for the three domains of life.Funding was received from the Research (Northern Ireland) and Enterprise Directorate of Queen’s University Belfast; Department of Agriculture and Rural Development and the Department for Employment and Learning (Northern Ireland); Biotechnology and Biological Sciences Research Council (BBSRC, UK) Projects BBF/003471/1 and BBF/00351X/1; and the Beaufort Marine Research Award for Marine Biodiscovery that is carried out under the Sea Change Strategy and the Strategy for Science Technology and Innovation (2006–2013), with the support of the Marine Institute, Ireland.

Centrality, rapidity and transverse momentum dependence of J/ψ suppression in Pb–Pb collisions at √sNN = 2.76 TeV

The inclusive J/ψ nuclear modification factor (RAA) in Pb–Pb collisions at √sNN = 2.76 TeV has been measured by ALICE as a function of centrality in the e+e− decay channel at mid-rapidity (|y| &lt; 0.8) and as a function of centrality, transverse momentum and rapidity in the μ+μ− decay channel at forward-rapidity (2.5 &lt; y &lt; 4). The J/ψ yields measured in Pb–Pb are suppressed compared to those in pp collisions scaled by the number of binary collisions. The RAA integrated over a centrality range corresponding to 90% of the inelastic Pb–Pb cross section is 0.72±0.06(stat.)±0.10(syst.) at mid- rapidity and 0.58 ± 0.01(stat.) ± 0.09(syst.) at forward- rapidity. At low transverse momentum, significantly larger values of RAA are measured at forward-rapidity compared to measurements at lower energy. These features suggest that a contribution to the J/ψ yield originates from charm quark (re)combination in the deconfined partonic medium
Evidence for the 125 GeV Higgs boson decaying to a pair of τ leptons

A search for a standard model Higgs boson decaying into a pair of τ leptons is performed using events recorded by the CMS experiment at the LHC in 2011 and 2012. The dataset corresponds to an integrated luminosity of 4.9 fb−1 at a centre-of-mass energy of 7 TeV and 19.7 fb−1 at 8 TeV. Each τ lepton decays hadronically or leptonically to an electron or a muon, leading to six different final states for the τ -lepton pair, all considered in this analysis. An excess of events is observed over the expected background contributions, with a local significance larger than 3 standard deviations for m H values between 115 and 130 GeV. The best fit of the observed H → τ τ signal cross section times branching fraction for m H = 125 GeV is 0.78 ± 0.27 times the standard model expectation. These observations constitute evidence for the 125 GeV Higgs boson decaying to a pair of τ leptons
Not far away from home: A relational distance-based approach to understand images of houses

Antanas L.-A., van Otterlo M., Oramas Mogrovejo J.A., Tuytelaars T., De Raedt L., ''Not far away from home: a relational distance-based approach to understand images of houses'', Lecture notes in computer science, vol. 6489, pp. 22-29, 2011 (20th international conference on inductive logic programming - ILP 2010, June 27-30, 2010, Firenze, Italy).Augmenting vision systems with high-level knowledge and reasoning can improve lower-level vision processes, such as object detection, with richer and more structured information. In this paper we tackle the problem of delimiting conceptual elements of street views based on spatial relations between lower-level components, e.g. the element ‘house’ is composed of windows and a door in a spatial arrangement. We use structured data: each concept can be seen as a graph representing spatial relations between components, e.g. in terms of right, up, close. We employ distances between logical interpretations to match parts of images with known examples and describe experimental results.status: publishe
Enhanced electrical and magnetic properties in La0.7Sr0.3MnO3 thin films deposited on CaTiO3-buffered silicon substrates

We investigate the suitability of an epitaxial CaTiO3 buffer layer deposited onto (100) Si by reactive molecular-beam epitaxy (MBE) for the epitaxial integration of the colossal magnetoresistive material La0.7Sr0.3MnO3 with silicon. The magnetic and electrical properties of La0.7Sr0.3MnO3 films deposited by MBE on CaTiO3-buffered silicon (CaTiO3/Si) are compared with those deposited on SrTiO3-buffered silicon (SrTiO3/Si). In addition to possessing a higher Curie temperature and a higher metal-to-insulator transition temperature, the electrical resistivity and 1/f noise level at 300 K are reduced by a factor of two in the heterostructure with the CaTiO3 buffer layer. These results are relevant to device applications of La0.7Sr0.3MnO3 thin films on silicon substrates
Asymptotic representations and q -oscillator solutions of the graded Yang–Baxter equation related to Baxter Q-operators

We consider a class of asymptotic representations of the Borel subalgebra of the quantum affine superalgebra Uq(glˆ(M|N)) . This is characterized by Drinfeld rational fractions. In particular, we consider contractions of Uq(gl(M|N)) in the FRT formulation and obtain explicit solutions of the graded Yang–Baxter equation in terms of q -oscillator superalgebras. These solutions correspond to L-operators for Baxter Q-operators. We also discuss an extension of these representations to the ones for contracted algebras of Uq(glˆ(M|N)) by considering the action of renormalized generators of the other side of the Borel subalgebra. We define model independent universal Q-operators as the supertrace of the universal R-matrix and write universal T-operators in terms of these Q-operators based on shift operators on the supercharacters. These include our previous work on Uq(slˆ(2|1)) case [1] in part, and also give a cue for the operator realization of our Wronskian-like formulas on T- and Q-functions in [2,3]
Universality in the geometric dependence of Rényi entropy

We derive several new results for Rényi entropy, S n , across generic entangling surfaces. We establish a perturbative expansion of the Rényi entropy, valid in generic quantum field theories, in deformations of a given density matrix. When applied to even-dimensional conformal field theories, these results lead to new constraints on the n -dependence, independent of any perturbative expansion. In 4d CFTs, we show that the n -dependence of the universal part of the ground state Rényi entropy for entangling surfaces with vanishing extrinsic curvature contribution is in fact fully determined by the Rényi entropy across a sphere in flat space. Using holography, we thus provide the first computations of Rényi entropy across non-spherical entangling surfaces in strongly coupled 4d CFTs. Furthermore, we address the possibility that in a wide class of 4d CFTs, the flat space spherical Rényi entropy also fixes the n -dependence of the extrinsic curvature contribution, and hence that of arbitrary entangling surfaces. Our results have intriguing implications for the structure of generic modular Hamiltonians
Anomalous triple gauge couplings from B -meson and kaon observables

We consider the three CP-conserving dimension-6 operators that encode the leading new-physics effects in the triple gauge couplings. The contributions to the standardmodel electromagnetic dipole and semi-leptonic vector and axial-vector interactions that arise from the insertions of these operators are calculated. We show that radiative and rare B -meson decays provide, under certain assumptions, constraints on two out of the three anomalous couplings that are competitive with the restrictions obtained from LEP II, Tevatron and LHC data. The constraints arising from the Z → b b ¯ $$ Z\to b\overline{b} $$ electroweak pseudo observables, K → π v v ¯ $$ K\to \pi v\overline{v} $$ and ϵ ′ / ϵ are also studied
Molecular characterization of an endophytic Phomopsis        liquidambaris CBR-15 from Cryptolepis buchanani Roem. and impact of culture media on biosynthesis of antimicrobial metabolites

An endophytic fungus Phomopsis liquidambaris CBR-15, was isolated from Cryptolepis buchanani Roem. (Asclepiadaceae) and identified by its characteristic culture morphology and molecular analysis of the ITS region of rDNA and intervening 5.8S rRNA gene. The impact of different culture media on biosynthesis of antimicrobial metabolites was tested by disc diffusion assay. Polyketide synthase gene (PKS) of the endophytic fungus was investigated using three pairs of degenerate primers LC1–LC2c, LC3–LC5c and KS3–KS4c by PCR. TLC-bioautography method was employed to detect the antimicrobial metabolites. Antimicrobial metabolites fractionated with ethyl acetate extract showed significant antimicrobial activity against the test bacteria and fungi. Biosynthesis of antimicrobial metabolites was optimum as depicted by zone of inhibition from ethyl acetate extract cultured in potato dextrose broth. Strain CBR-15 was identified as Phomopsis                liquidambaris and PKS genes of the fungus were amplified with LC3–LC5c and KS3–KS4c sets of degenerate primers. These findings suggest that endophytic P.                liquidambaris CBR-15 harbor iterative type I fungal PKS gene domain which indicates the biosynthetic potential of endophytic fungi as producers of natural antimicrobial metabolites. The study also demonstrates the utilization and optimization of different culture media which best supports for the biosynthesis of the antimicrobial metabolites from P.                liquidambaris
HQET at order 1/m: III Decay constants in the quenched approximation

We report on the computation of the Bs meson decay constant in Heavy Quark Effective Theory on the lattice. The next to leading order corrections in the HQET expansion are included non-perturbatively. We estimate higher order contributions to be very small. The results are extrapolated to the continuum limit, the main systematic error affecting the computation is therefore the quenched approximation used here. The Generalized Eigenvalue Problem and the use of all-to-all propagators are important technical ingredients of our approach that allow to keep statistical and systematic errors under control. We also report on the decay constant  fB′sfBs′  of the first radially excited state in the Bs sector, computed in the static limitDeutsche Forschungsgemeinschaf
Mechanosensitive neurons on the internal reproductive tract contribute to egg-laying-induced acetic acid attraction in Drosophila.

Selecting a suitable site to deposit their eggs is an important reproductive need of Drosophila females. Although their choosiness toward egg-laying sites is well documented, the specific neural mechanism that activates females' search for attractive egg-laying sites is not known. Here, we show that distention and contraction of females' internal reproductive tract triggered by egg delivery through the tract plays a critical role in activating such search. We found that females start to exhibit acetic acid (AA) attraction prior to depositing each egg but no attraction when they are not laying eggs. Artificially distending the reproductive tract triggers AA attraction in non-egg-laying females, whereas silencing the mechanosensitive neurons we identified that can sense the contractile status of the tract eliminates such attraction. Our work uncovers the circuit basis of an important reproductive need of Drosophila females and provides a simple model for dissecting the neural mechanism that underlies a reproductive need-induced behavioral modification
Search for squarks and gluinos in events with isolated leptons, jets and missing transverse momentum at root s=8 TeV with the ATLAS detector

The results of a search for supersymmetry in final states containing at least one isolated lepton (electron or muon), jets and large missing transverse momentum with the ATLAS detector at the Large Hadron Collider are reported. The search is based on proton-proton collision data at a centre-of-mass energy root s = 8 TeV collected in 2012, corresponding to an integrated luminosity of 20 fb(-1). No significant excess above the Standard Model expectation is observed. Limits are set on supersymmetric particle masses for various supersymmetric models. Depending on the model, the search excludes gluino masses up to 1.32 TeV and squark masses up to 840 GeV. Limits are also set on the parameters of a minimal universal extra dimension model, excluding a compactification radius of 1/R-c = 950 GeV for a cut-off scale times radius (Lambda R-c) of approximately 30.<p>ATLAS Collaboration, for complete list of authors see http://dx.doi.org/10.1007/JHEP04(2015)116</p
A model of plate motion

The wide use of space geodesy techniques devoted to geophysical and geodynamical purposes has recently evidenced some limitations due to the intrinsic Terrestrial Reference Frame (TRF) definition. Current TRFs are defined under hypotheses suited to overcome the rank deficiency of the observations with respect to the parameters that have to be estimated, i.e. coordinates and velocities (Dermanis, 2001; Dermanis, 2002).
From a geodetic point of view, one possibility implies the application of the no-net-rotation condition (NNR). One of the main geophysical consequences due to the application of this condition is that it allows only accurate estimations of relative motions, whilst other motions of geodynamical interest, for instance with respect to the inner layers of the Earth body, are not determinable.
The main purpose of this paper is to propose a unified way to describe plate motions, overcoming the problems introduced by the NNR condition, in order to establish a new reference frame useful for geodynamical applications too.
Since we believe relevant the role played by global tectonics inferences, we introduce the concept of the main tectonic sinusoid to propose an analytical description of the plate motions flow, which is polarized to the “west” in the hotspot reference frame
