The reliability of Turkish translation of quick exposure check (QEC) for risk assessment of work related musculoskeletal disorders

Work Related Musculo-Skeletal Disorders (WRMSDs) are a common health problem and one of the major causes of disability. Exposure to risk factors of musculoskeletal disorders and the change in exposure can be measured by observational assessment techniques. One of the techniques is QEC ( Quick Exposure Check), which was developed by Li and Buckle in 1998. We designed this study to translate QEC to Turkish and investigation of QEC's reliability among cleaners. The study was conducted among 20 cleaners who were randomly chosen from 200 subjects working at Istanbul University, Istanbul Medical Faculty Hospital. Test-retest reliability of QEC was investigated by intraclass correlation coefficient ( ICC) and Bland Altman method. The reliability coefficients of QEC items were found between 0.589 and 1. Among those QEC items, wrist hand position, back position, using vehicle, work period, were found statistically the most reliable between measurements. The items' reliability of QEC was generally fair to good. For this reason, we suggest that, QEC would be helpful for evaluation of WRMSD risk assessment to those who work in the field of work health and safety in the industry of Turkey

Combined search for anomalous pseudoscalar HVV couplings in VH production and H to VV decay

A search for anomalous pseudoscalar couplings of the Higgs boson H to electroweak vector bosons V (= W or Z) in a sample of proton-proton collision events corresponding to an integrated luminosity of 18.9 fb$^{-1}$ at a center-of-mass energy of 8 TeV is presented. Events consistent with the topology of associated VH production, where the Higgs boson decays to a pair of bottom quarks and the vector boson decays leptonically, are analyzed. The consistency of data with a potential pseudoscalar contribution to the HVV interaction, expressed by the effective pseudoscalar cross section fractions $f_{a_3}$, is assessed by means of profile likelihood scans. Results are given for the VH channels alone and for a combined analysis of the VH and previously published H $\rightarrow$ VV channels. Assuming the standard model ratio of the coupling strengths of the Higgs boson to top and bottom quarks, $f_{a_3}^{\mathrm{ZZ}}>0.0034$ is excluded at 95% confidence level in the combination

Measurements of ttˉt\bar t spin correlations and top quark polarization using dilepton final states in pp collisions at s\sqrt s = 8 TeV

Measurements of the top quark-antiquark (tt¯) spin correlations and the top quark polarization are presented for tt¯ pairs produced in pp collisions at s=8 TeV. The data correspond to an integrated luminosity of 19.5 fb−1 collected with the CMS detector at the LHC. The measurements are performed using events with two oppositely charged leptons (electrons or muons) and two or more jets, where at least one of the jets is identified as originating from a bottom quark. The spin correlations and polarization are measured from the angular distributions of the two selected leptons, both inclusively and differentially, with respect to the invariant mass, rapidity, and transverse momentum of the tt¯ system. The measurements are unfolded to the parton level and found to be in agreement with predictions of the standard model. A search for new physics in the form of anomalous top quark chromo moments is performed. No evidence of new physics is observed, and exclusion limits on the real part of the chromo-magnetic dipole moment and the imaginary part of the chromo-electric dipole moment are evaluated

Event generator tunes obtained from underlying event and multiparton scattering measurements

New sets of parameters ('tunes') for the underlying-event (UE) modeling of the PYTHIA8, PYTHIA6 and HERWIG++ Monte Carlo event generators are constructed using different parton distribution functions. Combined fits to CMS UE data at sqrt(s) = 7 TeV and to UE data from the CDF experiment at lower sqrt(s), are used to study the UE models and constrain their parameters, providing thereby improved predictions for proton-proton collisions at 13 TeV. In addition, it is investigated whether the values of the parameters obtained from fits to UE observables are consistent with the values determined from fitting observables sensitive to double-parton scattering processes. Finally, comparisons of the UE tunes to 'minimum bias' (MB) events, multijet, and Drell-Yan (q q-bar to Z / gamma* to lepton-antilepton + jets) observables at 7 and 8 TeV are presented, as well as predictions of MB and UE observables at 13 TeV
