REM near-IR and optical multiband observations of PKS 2155-304 in 2005

Context. Spectral variability is the main tool for constraining emission models of BL Lac objects. Aims. By means of systematic observations of the BL Lac prototype PKS 2155-304 in the infrared-optical band, we explore variability on scales of months, days, and hours. Methods. We made our observations with the robotic 60 cm telescope REM located at La Silla, Chile, and VRIJHK filters were used. Results. PKS 2155-304 was observed from May to December 2005. The wavelength interval explored, the total number of photometric points, and the short integration time render our photometry substantially superior to previous ones for this source. On the basis of the intensity and colour, we distinguish three different states of the source, each lasting months, which include all those described in the literature. In particular, we report the highest state ever detected in the H band. The source varied by a factor of 4 in this band,\ud
much more than in the V band (a factor ≈2). The source softened with increasing intensity, in contrast to the general pattern observed in the UV-X-ray bands. On five nights in November we had nearly continuous monitoring for 2–3 h. A variability episode on a time scale of τ ≈ 24 h is well-documented, and a much more rapid flare with τ = 1–2 h, is also apparent, but is supported by relatively few points. Conclusions. The overall spectral energy distribution of PKS 2155-304 is commonly described by a synchrotron-self-Compton model. The optical infrared emission is in excess of the expectation of the model in its original formulation. This can be explained by a variation in the frequency of the synchrotron peak, which is not unprecedented in BL Lacs.

A study of CP violation in B-+/- -> DK +/- and B-+/- -> D pi(+/-) decays with D -> (KSK +/-)-K-0 pi(-/+) final states

A first study of CP violation in the decay modes B-+/- -> [(KSK +/-)-K-0 pi(-/+)](D)h(+/-) and B-+/- -> [(KSK +/-)-K-0 pi(-/+)](D)h(+/-), where h labels a K or pi meson and D labels a D-0 or (D) over bar (0) meson, is performed. The analysis uses the LHCb data set collected in pp collisions, corresponding to an integrated luminosity of 3 fb(-1). The analysis is sensitive to the CP-violating CKM phase gamma through seven observables: one charge asymmetry in each of the four modes and three ratios of the charge-integrated yields. The results are consistent with measurements of gamma using other decay modes

W and Z boson production in p-Pb collisions at $\sqrt{s_{\rm NN}}$ =
  5.02 TeV

The W and Z boson production was measured via the muonic decay channel in
proton-lead collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV at the Large Hadron
Collider with the ALICE detector. The measurement covers backward ($-4.46 <
y_{\rm cms} < -2.96$) and forward ($2.03 < y_{\rm cms} < 3.53$) rapidity
regions, corresponding to Pb-going and p-going directions, respectively. The
Z-boson production cross section, with dimuon invariant mass of
$60<m_{\mu\mu}<120$ GeV/$c^2$ and muon transverse momentum ($p_{\rm T}^\mu$)
larger than 20 GeV/$c$, is measured. The production cross section and charge
asymmetry of muons from W-boson decays with $p_{\rm T}^\mu>10$ GeV/$c$ are
determined. The results are compared to theoretical calculations both with and
without including the nuclear modification of the parton distribution
functions. The W-boson production is also studied as a function of the
collision centrality: the cross section of muons from W-boson decays is found
to scale with the average number of binary nucleon-nucleon collisions within
uncertainties.Comment: 24 pages, 8 captioned figures, 3 tables, authors from page 18,

Sufficient conditions for Hamiltonicity in multiswapped networks.

OTIS networks are interconnection networks amenable to deployment as hybrid networks containing both electronic and optical links. Deficiencies as regards symmetry led to the subsequent formulation of biswapped networks which were later generalized to multiswapped networks so as to still enable optoelectronic implementation (as it happens, multiswapped networks also generalize previously studied hierarchical crossed cubes). Multiswapped networks of the form Msw(H;G) are known to possess good (graph-theoretic) properties as regards their use as (optoelectronic) interconnection networks (in distributed-memory multiprocessors) and in relation to those of the component networks G and H. Combinatorially they provide a hierarchical mechanism to define new networks from existing networks (so that the properties of the new network can be controlled in terms of the constituent networks). In this paper we prove that if G and H are Hamiltonian networks then the multiswapped network Msw(H;G) is also Hamiltonian. At the core of our proof is finding specially designed Hamiltonian cycles in 2-dimensional and heavily pruned 3-dimensional tori, irrespective of the actual networks G and H we happen to be working with. This lends credence to the role of tori as fundamental networks within the study of interconnection networks
Search for a Higgs boson in the diphoton final state using the full CDF data set from pp̅ collisions at √s = 1.96 TeV

A search for a narrow Higgs boson resonance in the diphoton mass spectrum is presented based on data corresponding to 10 fb[superscript −1] of integrated luminosity collected by the CDF experiment from proton–antiproton collisions at √s = 1.96 TeV. To increase the sensitivity of the search, we employ a multivariate discriminant technique for the first time in this channel at CDF. No evidence of signal is observed, and upper limits are set on the cross section times branching ratio of the resonant state as a function of the Higgs boson mass. The limits are interpreted in the context of the standard model with an expected (observed) limit on the cross section times branching ratio of 9.9 (17.0) times the standard model prediction at the 95% credibility level for a Higgs boson mass of 125 GeV/c[superscript 2]. Moreover, a Higgs boson with suppressed couplings to fermions is excluded for masses below 114 GeV/c[superscript 2] at the 95% credibility level.United States.

Search for first generation scalar leptoquarks in the evjj channel in pp collisions at √s = 7 TeV

A search for pair-production of first generation scalar leptoquarks is performed in the final state containing an electron, a neutrino, and at least two jets using proton–proton collision data at √s = 7 TeV. The data were collected by the CMS detector at the LHC, corresponding to an integrated luminosity of 36 pb[superscript −1]. The number of observed events is in good agreement with the predictions for standard model processes. Prior CMS results in the dielectron channel are combined with this electron + neutrino search. A 95% confidence level combined lower limit is set on the mass of a first generation scalar leptoquark at 339 GeV for β=0.5, where β is the branching fraction of the leptoquark to an electron and a quark. These results represent the most stringent direct limits to date for values of β greater than 0.05.United States. Dept. of EnergyNational Science Foundation (U.S.
Measurement of the time-integrated CP asymmetry in D0 → KS0KS0 decays

The time-integrated CP asymmetry in the decay D[superscript 0] → K[subscript S][superscript 0]K[subscript S][superscript 0] is measured using 3 fb[superscript −1] of proton-proton collision data collected by the LHCb experiment at centre-of-mass energies of 7 and 8 TeV. The flavour of the D[superscript 0] meson is determined by use of the decay D[superscript *+] → D[superscript 0]π[superscript +] and its charge conjugate mode. The result is A[subscript CP]=−0.029±0.052±0.022, where the first uncertainty is statistical and the second systematic. The result is consistent with Standard Model expectations and improves the uncertainty with respect to the only previous measurement of this quantity by more than a factor of three.National Science Foundation (U.S.
The mutable nature of particle-core excitations with spin in the one-valence-proton nucleus Sb-133

The gamma-ray decay of excited states of the one-valence-proton nucleus Sb-133 has been studied using cold-neutron induced fission of U-235 and Pu-241 targets, during the EXILL campaign at the ILL reactor in Grenoble. By using a highly efficient HPGe array, coincidences between gamma-rays prompt with the fission event and those delayed up to several tens of microseconds were investigated, allowing to observe, for the first time, high-spin excited states above the 16.6 mu s isomer. Lifetimes analysis, performed by fast-timing techniques with LaBr3(Ce) scintillators, revealed a difference of almost two orders of magnitude in B(M1) strength for transitions between positive-parity medium-spin yrast states. The data are interpreted by a newly developed microscopic model which takes into account couplings between core excitations (both collective and non-collective) of the doubly magic nucleus Sn-132 and the valence proton, using Skyrme effective interaction in a consistent way. The results point to a fast change in the nature of particle-core excitations with increasing spin. (C) 2016 The Authors. Published by Elsevier B.V.

Search for supersymmetry with jets, missing transverse momentum and at least one hadronically decaying tau lepton in proton-proton collisions at root s = 7 TeV with the ATLAS detector

A search for production of supersymmetric particles in final states containing jets, missing transverse momentum, and at least one hadronically decaying τ lepton is presented. The data were recorded by the ATLAS experiment in √s = 7 TeV proton–proton collisions at the Large Hadron Collider. No excess above the Standard Model background expectation was observed in 2.05 fb⁻¹ of data. The results are interpreted in the context of gauge mediated supersymmetry breaking models with Mmess = 250 TeV, N₅ = 3, μ > 0, and Cgrav = 1. The production of supersymmetric particles is excluded at 95% C.L. up to a supersymmetry breaking scale Λ = 30 TeV, independent of tanβ, and up to Λ = 43 TeV for large tanβ.G. Aad ... P. Jackson ...

Global Trends of "Green" Economy Development as a Factor for Improvement of Economical and Social Prosperity

The article covers main reasons of emerging a new type of economy, the "green" economy. The aims and objectives of developing green economy were analyzed. The significance of an economy reform carried out on both national and global levels was evaluated. We analyzed both speed and level of the green economy development in the world and in the most developed countries of the world. An influence of institutional and investment factors on the process of greening economy was studied. The authors evaluated an influence of scientific and technical researches on transition of economy to its new model. An influence of leading countries, economical global leaders, on greening interstate and global economy was reviewed and analyzed. Possible perspectives of the global green economy development and consequences of greening process are given. The article determines factors that influence on the level of economic and social prosperity and welfare of society. The authors show negative consequences of the existing economic model that influence the society level of living, poverty, prosperity and welfare. It is proved by Japan experience that contributions into development of “green” economy sectors and R&D works promote greening food, influence welfare of society and life expectancy. A conclusion was made that transition to green economy will favorably influence health level of any nation and increase factors that promote development of social and economic prosperity and welfare of society in general
ß-lactamasas producidas por enterobacterias resistentes a amoxicilina-ácido clavulánico aisladas en Buenos Aires, Argentina: un nuevo gen blaTEM

Resistance to β-lactam/β-lactamase inhibitors in enterobacteria is a growing problem that has not been intensively studied in Argentina.
In the present work, 54/843 enterobacteria collected in a teaching hospital of Buenos Aires city were ampicillin-sulbactam-resistant isolates remaining susceptible to second- and third-generation cephalosporins. The enzymatic mechanisms present in the isolates, which were also amoxicillin-clavulanic acid (AMC)-resistant (18/54) were herein analyzed.
Sequencing revealed two different variants of blaTEM-1, being blaTEM-1b the most frequently detected allelle (10 Escherichia coli, 3 Klebsiella pneumoniae, 2 Proteus mirabilis and 1 Raoultella terrigena) followed by blaTEM-1a (1 K. pneumoniae). Amoxicillin-clavulanate resistance seems to be mainly associated with TEM-1 overproduction (mostly in E. coli) or co-expressed with OXA-2-like and/or SHV β-lactamases (K. pneumoniae and P. mirabilis).
A new blaTEM variant (TEM-163) was described in an E. coli strain having an AMC MIC value of 16/8 μg/ml. TEM-163 contains Arg275Gln and His289Leu amino acid substitutions. On the basis of the high specific activity and low IC50 for clavulanic acid observed, the resistance pattern seems to be due to overproduction of the new variant of broad spectrum β-lactamase rather than to an inhibitor-resistant TEM (IRT)-like behavior.Fil: Di Conza, José Alejandro.

Clinical ethical dilemmas for vascular surgeons (The vascuethics study) : are self-interest attitudes related to profeccional seniority

Producción CientíficaObjective. To evaluate the association between professional seniority and self-interest (PSI) attitudes in the resolution of
vascular ethical dilemmas (VED).
Design. Cross-sectional.
Subjects. Vascular surgeons (residents included) from the 28 vascular teaching departments of Spain.
Measurements. Multidisciplinary team-designed questionnaire of 5 VED. Each VED had 3 different answers (attitudes): 2
favouring legitimate ethical attitudes (LEA) and 1 favouring PSI. The questionnaire was self-administered and all
participants stated their degree of agreement with each answer on a continuous Likert scale. PSI was evaluated by: (1) adding
the magnitudes of the 5 answers favouring PSI (absPSI); and (2) by comparing in each case the magnitude of the PSI answer
with that of the 2 LEA (relPSI).
Statistics. Linear regression adjusted by confounding factors.
Results. Two hundred and fifty-three vascular surgeons from the 26 participating teaching vascular departments of public
hospitals completed the questionnaire (87.5% surgeons/department). Surgeon characteristics were: (1) median age 37 years;
(2) 187 (74%) male; (3) 59 (23%) brought up with a health professional relative; (4) 94 (38%) had additional private
practice; (5) 133 (65%) professed religious beliefs; and (6) 1–10 years of experience in 116 (47%), 11–20 years in 58 (24%),
21–30 years in 57 (23%), and .30 years in 15 (6%). The multivariate analysis disclosed that for every 10-years rise in
professional seniority there was a 3.2% increase in absPSI (p ¼ 0.007, adjusted by variables 3 and 4), and a 3.4% increase in
relPSI (p ¼ 0.002, adjusted by variable 5).
Conclusions. Professional seniority is associated with a slight increase in pro-PSI attitudes in cases of vascular ethical
dilemma. Both vascular surgeons and health institutions should promote the reversal of this worrying tendency
Phases of QCD with nonvanishing isospin density

AbstractThe propagation of low-momentum baryons through QCD matter at low isospin density is studied using chiral perturbation theory. When the isospin chemical potential exceeds a critical value, the dispersion relation for the lowest nucleon mode becomes anomalous near zero momentum — increasing momentum yields decreasing energy — so that the momentum for the lowest energy state, pmin, becomes nonzero. This can be interpreted as a new phase of QCD, with pmin serving as the order parameter and the kinetic mass (defined as the inverse of the second derivative of the energy with respect to the momentum at pmin) serving as the susceptibility. A lowest-order chiral-perturbation-theory calculation yields a critical isospin chemical potential of ∼285 MeV. Since this is small compared to the chiral-symmetry-breaking scale, corrections to it are likely to be modest
Nagging: A scalable fault-tolerant paradigm for distributed search

AbstractThis paper describes nagging, a technique for parallelizing search in a heterogeneous distributed computing environment. Nagging exploits the speedup anomaly often observed when parallelizing problems by playing multiple reformulations of the problem or portions of the problem against each other. Nagging is both fault tolerant and robust to long message latencies. In this paper, we show how nagging can be used to parallelize several different algorithms drawn from the artificial intelligence literature, and describe how nagging can be combined with partitioning, the more traditional search parallelization strategy. We present a theoretical analysis of the advantage of nagging with respect to partitioning, and give empirical results obtained on a cluster of 64 processors that demonstrate nagging's effectiveness and scalability as applied to A∗ search, αβ minimax game tree search, and the Davis–Putnam algorithm
Tellurium n-type doping of highly mismatched amorphous GaN1−xAsx alloys in plasma-assisted molecular beam epitaxy

AbstractIn this paper we report our study on n-type Te doping of amorphous GaN1−xAsx layers grown by plasma-assisted molecular beam epitaxy. We have used a low temperature PbTe source as a source of tellurium. Reproducible and uniform tellurium incorporation in amorphous GaN1−xAsx layers has been successfully achieved with a maximum Te concentration of 9×1020cm−3. Tellurium incorporation resulted in n-doping of GaN1−xAsx layers with Hall carrier concentrations up to 3×1019cm−3 and mobilities of ~1cm2/Vs. The optimal growth temperature window for efficient Te doping of the amorphous GaN1−xAsx layers has been determined
A perturbation solution for forced convection in a porous-saturated duct

AbstractFully developed forced convection through a porous medium bounded by two isoflux parallel plates is investigated analytically on the basis of a Brinkman–Forchheimer model. The matched asymptotic expansion method is applied for small values of the Darcy number. For the case of large Darcy number the solution for the Brinkman–Forchheimer momentum equation is found in terms of an asymptotic expansion. With the velocity distribution determined, the energy equation is solved using the same asymptotic technique. The results for limiting cases are found to be in good agreement with those available in the literature and the numerical results obtained here
Calibrating 30 Years of Experimental Research: A Meta-Analysis of the Atmospheric Effects of Music, Scent, and Color

AbstractAtmospheric in-store stimuli have been the subject of considerable empirical investigation for over 30 years. This research presents a meta-analysis of 66 studies and 135 effects (N=15,621) calibrating the atmospheric effects of music, scent, and color on shopping outcomes. At an aggregate level, the results reveal that environments in which music or scent are present yield higher pleasure, satisfaction, and behavioral intention ratings when compared with environments in which such conditions are absent. Warm colors produce higher levels of arousal than cool colors, while cool colors produce higher levels of satisfaction than warm colors. The estimated average strength of these relationships ranged from small to medium. Effect sizes exhibited significant between-study variance, which can be partly explained by the moderators investigated. For instance, larger effect sizes were observed for the relationship between scent and pleasure in those samples with a higher (vs. lower) proportion of females. Data also indicated a tendency toward stronger music and scent effects in service settings as compared to retail settings. The results of this analysis, based on data aggregated across the research stream, offer retailers a guide to enhance customers’ shopping experience through judicious use of in-store atmospheric stimuli
Longitudinal Study of Recurrent Metastatic Melanoma Cell Lines Underscores the Individuality of Cancer Biology

Recurrent metastatic melanoma provides a unique opportunity to analyze disease evolution in metastatic cancer. Here, we followed up eight patients with an unusually prolonged history of metastatic melanoma, who developed a total of 26 recurrences over several years. Cell lines derived from each metastasis were analyzed by comparative genomic hybridization and global transcript analysis. We observed that conserved, patient-specific characteristics remain stable in recurrent metastatic melanoma even after years and several recurrences. Differences among individual patients exceeded within-patient lesion variability, both at the DNA copy number (P<0.001) and RNA gene expression level (P<0.001). Conserved patient-specific traits included expression of several cancer/testis antigens and the c-kit proto-oncogene throughout multiple recurrences. Interestingly, subsequent recurrences of different patients did not display consistent or convergent changes toward a more aggressive disease phenotype. Finally, sequential recurrences of the same patient did not descend progressively from each other, as irreversible mutations such as homozygous deletions were frequently not inherited from previous metastases. This study suggests that the late evolution of metastatic melanoma, which markedly turns an indolent disease into a lethal phase, is prone to preserve case-specific traits over multiple recurrences and occurs through a series of random events that do not follow a consistent stepwise process
