We present an implementation of the Yennie-Frautschi-Suura (YFS) scheme for all-orders resummation logarithms from emission soft real and virtual photons in processes that are critical future lepton colliders. They include, particular, e^-e^+\to f\bar{f} e−<...

Triple gauge boson hadroproduction, in particular the production of three W-bosons at the LHC, is considered at next-to leading order accuracy in QCD. The NLO matrix elements are combined with parton showers. Multijet merging is invoked such that NLO matrix elements with one additional jet are also included. The studies here incorporate both the signal and all relevant backgrounds for VH produc...

Measurements are reported of differential cross sections for the production of a W boson, which decays into a muon and a neutrino, in association with jets, as a function of several variables, including the transverse momenta (pT) and pseudorapidities of the four leading jets, the scalar sum of jet transverse momenta (HT), and the difference in azimuthal angle between the directions of each jet...

An online survey of institutional repository (IR) managers identified copyright clearance trends in staffing and workflows. The majority of respondents followed a mediated deposit model, and reported that library personnel, instead of authors, engaged in copyright clearance activities for IRs. The most common “information gaps” pertained to the breadth of information in copyright directories li...

We present the cross sections for production of up to four jets at the Large Hadron Collider, at next-to-leading order in the QCD coupling. We use the BLACKHAT library in conjunction with SHERPA and a recently developed algorithm for assembling primitive amplitudes into color-dressed amplitudes. We adopt the cuts used by ATLAS in their study of multijet events in pp collisions at √s=7 TeV. We i...

original article   introduction: human errors are of the most important issues due to the technological advances in various work settings. in medical professions, including nursing, investigation of human errors would help to find out approaches for the identification and reduction of these errors. hence, the present study aimed to identify and assess nurses' errors in emergency ward of an educ...
