Search for new resonances in Wγ and Zγ final states in pp collisions at s√=8 TeV with the ATLAS detector

This Letter presents a search for new resonances decaying to final states with a vector boson produced
in association with a high transverse momentum photon, V γ , with V = W (→  ν) or Z(→  + −), where
  = e or μ. The measurements use 20.3 fb−1 of proton–proton collision data at a center-of-mass energy
of √s = 8 TeV recorded with the ATLAS detector. No deviations from the Standard Model expectations are
found, and production cross section limits are set at 95% confidence level. Masses of the hypothetical aT
and ωT states of a benchmark Low Scale Technicolor model are excluded in the ranges [275, 960] GeV and
[200, 700] ∪ [750, 890] GeV, respectively. Limits at 95% confidence level on the production cross section
of a singlet scalar resonance decaying to Zγ final states have also been obtained for masses below
1180 GeV.We acknowledge the support of ANPCyT, Argentina; YerPhI, Armenia; ARC, Australia; BMWFW and FWF, Austria; ANAS, Azerbaijan; SSTC, Belarus; CNPq and FAPESP, Brazil; NSERC, NRC and CFI, Canada; CERN; CONICYT, Chile; CAS, MOST and NSFC, China; COLCIENCIAS, Colombia; MSMT CR, MPO CR and VSC CR, Czech Republic; DNRF, DNSRC and Lundbeck Foundation, Denmark; EPLANET, ERC and NSRF, European Union; IN2P3-CNRS, CEA-DSM/IRFU, France; GNSF, Georgia; BMBF, DFG, HGF, MPG and AvH Foundation, Germany; GSRT and NSRF, Greece; ISF, MINERVA, GIF, I-CORE and Benoziyo Center, Israel; INFN, Italy; MEXT and JSPS, Japan; CNRST, Morocco; FOM and NWO, Netherlands; BRF and RCN, Norway; MNiSW and NCN, Poland; GRICES and FCT, Portugal; MNE/IFA, Romania; MES of Russia and ROSATOM, Russian Federation; JINR; MSTD, Serbia; MSSR, Slovakia; ARRS and MIZS, Slovenia; DST/NRF, South Africa; MINECO, Spain; SRC and Wallenberg Foundation, Sweden; SER, SNSF and Cantons of Bern and Geneva, Switzerland; NSC, Taiwan; TAEK, Turkey; STFC, the Royal Society and Leverhulme Trust, United Kingdom; DOE and NSF, United States of America
International comparisons of behavioral and emotional problems in preschool children: parents' reports from 24 societies

International comparisons were conducted of preschool children's behavioral and emotional problems as reported on the Child Behavior Checklist for Ages 11/2-5 by parents in 24 societies (N=19,850). Item ratings were aggregated into scores on syndromes; Diagnostic and Statistical Manual of Mental Disorders-oriented scales; a Stress Problems scale; and Internalizing, Externalizing, and Total Problems scales. Effect sizes for scale score differences among the 24 societies ranged from small to medium (3-12%). Although societies differed greatly in language, culture, and other characteristics, Total Problems scores for 18 of the 24 societies were within 7.1 points of the omnicultural mean of 33.3 (on a scale of 0-198). Gender and age differences, as well as gender and age interactions with society, were all very small (effect sizes1%). Across all pairs of societies, correlations between mean item ratings averaged .78, and correlations between internal consistency alphas for the scales averaged .92, indicating that the rank orders of mean item ratings and internal consistencies of scales were very similar across diverse societies
Search for new phenomena in dijet mass and angular distributions from pp collisions at √s=13 TeV with the ATLAS detector

This Letter describes a model-agnostic search for pairs of jets (dijets) produced by resonant and non-resonant phenomena beyond the Standard Model in 3.6fb−1of proton–proton collisions with a centre-of-mass energy of √s=13TeVrecorded by the ATLAS detector at the Large Hadron Collider. The distribution of the invariant mass of the two leading jets is examined for local excesses above a data-derived estimate of the smoothly falling prediction of the Standard Model. The data are also compared to a Monte Carlo simulation of Standard Model angular distributions derived from the rapidity of the two jets. No evidence of anomalous phenomena is observed in the data, which are used to exclude, at 95% CL, quantum black holes with threshold masses below 8.3TeV, 8.1TeV, or 5.1TeVin three different benchmark scenarios; resonance masses below 5.2TeVfor excited quarks, 2.6TeVin a Wmodel, a range of masses starting from mZ=1.5TeVand couplings from gq=0.2in a Zmodel; and contact interactions with a compositeness scale below 12.0TeVand 17.5TeVrespectively for destructive and constructive interference between the new interaction and QCD processes. These results significantly extend the ATLAS limits obtained from 8 TeV data. Gaussian-shaped contributions to the mass distribution are also excluded if the effective cross-section exceeds values ranging from approximately 50–300fb for masses below 2TeVto 2–20fb for masses above 4TeV
Violence, suffering, and mental health in Afghanistan : a school-based survey.

Background:\ud
Studies in Afghanistan have shown substantial mental health problems in adults. We did a survey of young people (11–16 years old) in the country to assess mental health, traumatic experiences, and social functioning.\ud
\ud
Methods:\ud
In 2006, we interviewed 1011 children, 1011 caregivers, and 358 teachers, who were randomly sampled in 25 government-operated schools within three purposively chosen areas (Kabul, Bamyan, and Mazar-e-Sharif municipalities). We assessed probable psychiatric disorder and social functioning in students with the Strength and Difficulties Questionnaire multi-informant (child, parent, teacher) ratings. We also used the Depression Self-Rating Scale and an Impact of Events Scale. We assessed caregiver mental health with both international and culturally-specific screening instruments (Self-Reported Questionnaire and Afghan Symptom Checklist). We implemented a checklist of traumatic events to examine the exposure to, and nature of, traumatic experiences. We analysed risk factors for mental health and reports of traumatic experiences.\ud
\ud
Findings:\ud
Trauma exposure and caregiver mental health were predictive across all child outcomes. Probable psychiatric ratings were associated with female gender (odds ratio [OR] 2·47, 95% CI 1·65–3·68), five or more traumatic events (2·58, 1·36–4·90), caregiver mental health (1·11, 1·08–1·14), and residence areas (0·29, 0·17–0·51 for Bamyan and 0·37, 0·23–0·57 for Mazar-e-Sharif vs Kabul). The same variables predicted symptoms of depression. Two thirds of children reported traumatic experiences. Symptoms of post-traumatic stress were associated with five or more traumatic events (3·07, 1·78–5·30), caregiver mental health (1·06, 1·02–1·09), and child age (1·19, 1·04–1·36). Children's most distressing traumatic experiences included accidents, medical treatment, domestic and community violence, and war-related events.\ud
\ud
Interpretation:\ud
Young Afghans experience violence that is persistent and not confined to acts of war. Our study emphasises the value of school-based initiatives to address child mental health, and the importance of understanding trauma in the context of everyday forms of suffering, violence, and adversity
The SNO solar neutrino data, neutrinoless double-beta decay and neutrino mass spectrum.

Assuming 3-nu mixing and massive Majorana neutrinos, we analyze the implications of the results of the solar neutrino experiments, including the latest SNO data, which favor the LMA MSW solution of the solar neutrino problem with tan(2) thetacircle dot < 1, for the predictions of the effective Majorana mass I (m) I in neutrinoless double beta-decay. Neutrino mass spectra with normal mass hierarchy, with inverted hierarchy and of quasi-degenerate type are considered. For cos 2thetacircle dotgreater than or similar to 0.26, which follows (at 99.73% C.L.) from the SNO analysis of the solar neutrino data, we find significant lower limits on I (m) I in the cases of quasi-degenerate and inverted hierarchy neutrino mass spectrum, \<m>\ greater than or similar to 0.035 eV and \<m>\ greater than or similar to 8.5 x 10(-3) eV, respectively. If the spectrum is hierarchical the upper limit holds \<m>\ greater than or similar to 8.2 x 10(-3) eV. Correspondingly, not only a measured value of \<m>\ not equal 0, but even an experimental upper limit on I (m) I of the order of few x 10(-2) eV can provide information on the type of the neutrino mass spectrum; it can provide also a significant upper limit on the mass of the lightest neutrino m(1)
The KeV Majoron as a dark matter particle

We consider a very weakly interacting KeV majoron as dark matter particle (DMP), which provides both the critical density ρcr=1.88×10−29h2 g/cm3 and the galactic scale Mgal ∼m3Pl/m2J∼1012M⊙(mJ/1KeV)−2 for galaxy formation. The majoron couples to leptons only through some new 'directly interacting particles', called DIPS, and this provides the required smallness of the coupling constants. If the masses of these DIPS are greater than the scale Vs characterizing the spontaneous violation of the global lepton symmetry they are absent at the corresponding phase transition (T∼Vs) and the majorons are produced during the phase transition, never being in thermal equilibrium during the history of the universe. In the alternative case mDIP<Vs the majorons can be for a short period in thermal equilibrium. This scenario is not forbidden by nucleosynthesis and gives a reasonable growth factor for the density fluctuations compatible with COBE. A possible signature is an X-ray line at Eγ=mJ2, produced by the decay J→γ+γ. A model is described which realizes the possibility of the KeV majoron as DMP and may also lead to observable rates for decays such as $\mu \ra e \gamma$ and $\mu \ra 3e$
Measurement of CP asymmetry in B-s(0) -> D-s(-/+) K-/+ decays

We report on measurements of the time-dependent CP violating observables in B-s(0) -> D-s(-/+) K--/+ decays using a dataset corresponding to 1.0 fb(-1) of pp collisions recorded with the LHCb detector. We find the CP violating observables C-f = 0.53 +/- 0.25 +/- 0.04, A(f)(Delta Gamma) = 0.37 +/- 0.42 +/- 0.20, A((f) over bar)(Delta Gamma) = 0.20 +/- 0.41 +/- 0.20, S-f = -1.09 +/- 0.33 +/- 0.08, S-(f) over bar = -0.36 +/- 0.34 +/- 0.08, where the uncertainties are statistical and systematic, respectively. Using these observables together with a recent measurement of the B-s(0) mixing phase -2 beta(s) leads to the first extraction of the CKM angle gamma from B-s(0) -> D-s(-/+) K--/+ decays, finding gamma = (115(-43)(+28))degrees modulo 180 degrees at 68% CL, where the error contains both statistical and systematic uncertainties
Response monitoring with [(18)F]FLT PET and diffusion-weighted MRI after cytotoxic 5-FU treatment in an experimental rat model for colorectal liver metastases

PURPOSE: The aim of the study was to investigate the potential of diffusion-weighted magnetic resonance imaging (DW-MRI) and 3'-dexoy-3'-[(18)F]fluorothymidine ([(18)F]FLT) positron emission tomography (PET) as early biomarkers of treatment response of 5-fluorouracil (5-FU) in a syngeneic rat model of colorectal cancer liver metastases. PROCEDURES: Wag/Rij rats with intrahepatic syngeneic CC531 tumors were treated with 5-FU (15, 30, or 60 mg/kg in weekly intervals). Before treatment and at days 1, 3, 7, and 14 after treatment rats underwent DW-MRI and [(18)F]FLT PET. Tumors were analyzed immunohistochemically for Ki67, TK1, and ENT1 expression. RESULTS: 5-FU inhibited the growth of CC531 tumors in a dose-dependent manner. Immunohistochemical analysis did not show significant changes in Ki67, TK1, and ENT1 expression. However, [(18)F]FLT SUVmean and SUVmax were significantly increased at days 4 and 7 after treatment with 5-FU (60 mg/kg) and returned to baseline at day 14 (SUVmax at days -1, 4, 7, and 14 was 1.1 ± 0.1, 2.3 ± 0.5, 2.3 ± 0.6, and 1.5 ± 0.4, respectively). No changes in [(18)F]FLT uptake were observed in the nontreated animals. Furthermore, the apparent diffusion coefficient (ADCmean) did not change in 5-FU-treated rats compared to untreated rats. CONCLUSION: This study suggests that 5-FU treatment induces a flare in [(18)F]FLT uptake of responsive CC531 tumors in the liver, while the ADCmean did not change significantly. Future studies in larger groups are warranted to further investigate whether [(18)F]FLT PET can discriminate between disease progression and treatment response
Search for the Standard Model Higgs boson in the decay channel H→ZZ(*)→4ℓ with the ATLAS detector

A search for the Standard Model Higgs boson in the decay channel H→ZZ(*)→ℓ[superscript +]ℓ[superscript −]ℓ′[superscript +]ℓ′[superscript −], where ℓ=e,μ is presented. Proton–proton collision data at √s = 7 TeV recorded with the ATLAS detector and corresponding to an average integrated luminosity of 2.1 fb[superscript −1] are compared to the Standard Model expectations. Upper limits on the production cross section of a Standard Model Higgs boson with a mass between 110 and 600 GeV600 GeV are derived. The observed (expected) 95% confidence level upper limit on the production cross section for a Higgs boson with a mass of 194 GeV, the region with the best expected sensitivity for this search, is 0.99 (1.01) times the Standard Model prediction. The Standard Model Higgs boson is excluded at 95% confidence level in the mass ranges 191–197, 199–200 and 214–224 GeV.European Organization for Nuclear ResearchUnited States.

Measurements of prompt charm production cross-sections in $pp$ collisions at $\sqrt{s} = 13\,\mathrm{TeV}$

Production cross-sections of prompt charm mesons are measured with the first data from $pp$ collisions at the LHC at a centre-of-mass energy of $13\,\mathrm{TeV}$. The data sample corresponds to an integrated luminosity of $4.98 \pm 0.19\,\mathrm{pb}^{-1}$ collected by the LHCb experiment. The production cross-sections of $D^{0}$, $D^{+}$, $D_{s}^{+}$, and $D^{*+}$ mesons are measured in bins of charm meson transverse momentum, $p_{\mathrm{T}}$, and rapidity, $y$, and cover the range $0 p_{\mathrm{T}} 15\,\mathrm{GeV}/c$ and $2.0 y 4.5$. The inclusive cross-sections for the four mesons, including charge conjugation, within the range of $1 p_{\mathrm{T}} 8\,\mathrm{GeV}/c$ are found to be \begin{equation*} \sigma(pp \to D^{0} X) = 2470 \pm \phantom{1}3 \pm 130\,\mu\mathrm{b} \end{equation*} \begin{equation*} \sigma(pp \to D^{+} X) = 1000 \pm \phantom{1}3 \pm 110\,\mu\mathrm{b} \end{equation*} \begin{equation*} \sigma(pp \to D_{s}^{+} X) = 460 \pm 13 \pm 100\,\mu\mathrm{b} \end{equation*} \begin{equation*} \sigma(pp \to D^{*+} X) = 880 \pm \phantom{1}5 \pm 140\,\mu\mathrm{b} \end{equation*} where the uncertainties are due to statistical and systematic uncertainties, respectively
Measurement of the W boson helicity fractions in the decays of top quark pairs to lepton + jets final states produced in pp collisions at $\sqrt{s}$ = 8 TeV

The W boson helicity fractions from top quark decays in $t\overline{t}$ events are measured using data from proton–proton collisions at a centre-of-mass energy of 8TeV. The data were collected in 2012 with the CMS detector at the LHC, corresponding to an integrated luminosity of 19.8fb$^{−1}$. Events are reconstructed with either one muon or one electron, along with four jets in the final state, with two of the jets being identified as originating from b quarks. The measured helicity fractions from both channels are combined, yielding $F_{0}=0.681±0.012(stat)±0.023(syst)$ , $F_{L}=0.323±0.008(stat)±0.014(syst)$, and $F_{R}=−0.004±0.005(stat)±0.014(syst)$ for the longitudinal, left-, and right-handed components of the helicity, respectively. These measurements of the W boson helicity fractions are the most accurate to date and they agree with the predictions from the standard model
Associations of objectively measured moderate-to-vigorous-intensity physical activity and sedentary time with all-cause mortality in a population of adults at high risk of type 2 diabetes mellitus.

Supplementary data to this article can be found online at http://dx.doi.org/10.1016/j.pmedr.2017.01.013.The relationships of physical activity and sedentary time with all-cause mortality in those at high risk of type 2 diabetes mellitus (T2DM) are unexplored. To address this gap in knowledge, we examined the associations of objectively measured moderate-to-vigorous-intensity physical activity (MVPA) and sedentary time with all-cause mortality in a population of adults at high risk of T2DM. In 2010-2011, 712 adults (Leicestershire, U.K.), identified as being at high risk of T2DM, consented to be followed up for mortality. MVPA and sedentary time were assessed by accelerometer; those with valid data (≥ 10 hours of wear-time/day with ≥ 4 days of data) were included. Cox proportional hazards regression models, adjusted for potential confounders, were used to investigate the independent associations of MVPA and sedentary time with all-cause mortality. 683 participants (250 females (36.6%)) were included and during a mean follow-up period of 5.7 years, 26 deaths were registered. Every 10% increase in MVPA time/day was associated with a 5% lower risk of all-cause mortality [Hazard Ratio (HR): 0.95 (95% Confidence Interval (95% CI): 0.91, 0.98); p = 0.004]; indicating that for the average adult in this cohort undertaking approximately 27.5 minutes of MVPA/day, this benefit would be associated with only 2.75 additional minutes of MVPA/day. Conversely, sedentary time showed no association with all-cause mortality [HR (every 10-minute increase in sedentary time/day): 0.99 (95% CI: 0.95, 1.03); p = 0.589]. These data support the importance of MVPA in adults at high risk of T2DM. The association between sedentary time and mortality in this population needs further investigation.This research was supported by the National Institute for Health Research (NIHR) Diet, Lifestyle & Physical Activity Biomedical Research Unit (BRU) based at University Hospitals of Leicester and Loughborough University, the National Institute for Health Research Collaboration for Leadership in Applied Health Research and Care – East Midlands (NIHR CLAHRC – EM) and the Leicester Clinical Trials Unit.Peer-reviewedPublisher Versio
Evaluating City Logistics Measure in E-Commerce with Multiagent Systems

AbstractThis paper presents a multi-agent systems (MAS) model to evaluate City Logistics measure for an urban road network in an e-commerce delivery system environment. Most notable contribution of this evaluation methodology is the combination of vehicle routing and scheduling problem with time window (VRPTW), auction theory and reinforcement learning in a multi-agent framework. This approach seeks to represent the behaviour of each stakeholder involved in the delivery of goods between producers and customers. The preliminary results of the model shows that Government-driven City Logistics measures such as freight vehicle road pricing has the potential of reducing truck emission when the administrator learns and price the road links
Association between hypertension and variation in the α- and β-adducin genes in a white population

Association between hypertension and variation in the α- and β-adducin genes in a white population.BackgroundThe substitution of tryptophan for glycine at amino acid 460 (Gly460Trp polymorphism) of the α-subunit of the heterodimeric cytoskeleton protein adducin increases renal sodium reabsorption and may be involved in the pathophysiology of essential hypertension. In the present study, we investigated in multivariate analyses whether the risk of hypertension was associated with the C1797T polymorphism of the β-adducin gene.MethodsA total of 1848 subjects randomly selected from a white population were genotyped. Study nurses measured blood pressure at the participants' homes.ResultsThe frequencies of the α-adducin Trp and β-adducin T alleles were 0.23 and 0.11, respectively. In men (N = 904), the β-adducin T allele was not associated with hypertension [adjusted relative risk (RR) vs. CC homozygotes 0.94, P = 0.77], but T allele carriers had lower plasma renin activity (PRA) and 24-hour urinary aldosterone excretion (P < 0.04). In all women (N = 944), β-adducin T allele carriers had a higher risk of hypertension than CC homozygotes (RR 1.81, CI 1.18–2.77, P = 0.007), but similar PRA and 24-hour urinary aldosterone excretion (P> 0.29). In 345 post-menopausal women and 190 users of oral contraceptives, the RRs of hypertension were 2.47 (CI 1.34–4.64, P = 0.003) and 2.56 (CI 0.83–7.86, P = 0.10), respectively. For systolic pressure in women, there was a significant interaction (P = 0.02) between the α- and β-adducin polymorphisms. Only in female carriers of the mutated α-adducin Trp allele was the systolic pressure significantly higher in β-adducin T allele carriers compared with CC homozygotes (+3.8mm Hg, P = 0.02). Furthermore, in the presence of the mutated α-adducin Trp allele, the RRs associated with the β-adducin T allele were 2.35 (P = 0.01) in all women, 2.92 (P = 0.03) in post-menopausal subjects, and 3.79 (P = 0.09) in users of oral contraceptives.ConclusionsThe 1797T allele of the β-adducin gene is associated with increased risk of hypertension in post-menopausal women and in users of oral contraceptives, particularly in the presence of the mutated α-adducin Trp allele. We hypothesize that inhibition of the renin-aldosterone system in men and absence of such a compensatory mechanism in women may explain, at least to some extent, the sexual dimorphism of the blood pressure phenotype in relation to the C1797T β-adducin polymorphism
Performance Improvement of Data Mining in Weka through GPU Acceleration

AbstractData mining tools may be computationally demanding, so there is an increasing interest on parallel computing strategies to improve their performance. The popularization of Graphics Processing Units (GPUs) increased the computing power of current desktop computers, but desktop-based data mining tools do not usually take full advantage of these architectures. This paper exploits an approach to improve the performance of Weka, a popular data mining tool, through parallelization on GPU-accelerated machines. From the profiling of Weka object-oriented code, we chose to parallelize a matrix multiplication method using state-of-the-art tools. The implementation was merged into Weka so that we could analyze the impact of parallel execution on its performance. The results show a significant speedup on the target parallel architectures, compared to the original, sequential Weka code
