Motivated by ongoing new physics searches in the top-quark sector at Large Hadron Collider we report on calculation of NLO QCD corrections to Standard Model $pp\to t\bar{t}Z+X$ process tetra-lepton decay channel. This is based matrix elements for $e^+ \nu_e\, \mu^-\bar{\nu}_\mu\, b\bar{b} \,\tau^+\tau^-$ final state and includes all resonant non-resonant Feynman diagrams, interferences off-shel...

New stellar models which track the production and destruction of He (and D) have been evolved for a range of stellar masses (0:65 M=M 100), metallicities (0:01 Z=Z 1) and initial (main sequence) He mass fractions (10 5 X3;MS 10 ). Armed with the He yields from these stellar models we have followed the evolution of D and He using a variety of chemical evolution models with and without infall of ...

This article presents the results of a survey carried out on leading periodicals in the areas of Ergonomics, Physiotherapy and Occupational Therapy, the aim of which was to identify scientific publications on the inclusion at work of people with disabilities. The survey of articles published on this topic in the following journals was conducted in December 2010: Applied Ergonomics, Ergonomics, ...

We have calculated the next-to-leading order cross section for the inclusive production of charm quarks as a function of the transverse momentum pT and the rapidity in two approaches using massive or massless charm quarks. For the singleresolved cross section we have derived the massless limit from the massive theory. We find that this limit differs from the genuine massless version with MS fac...

The aim of the study is to evaluate different production systems in pig farming including economic, animal welfare and environmental aspects with computer simulation. The computer model considers a vertically integrated system with farrowing, weaning, fattening and slaughtering stage as well as the transportation of pigs between theses stages. Housing systems were distinguished in individual an...

Most existing theoretical models of photodynamic therapy (PDT) assume a uniform initial distribution of the photosensitive molecule, Protoporphyrin IX (PpIX). This is an adequate assumption when the prodrug is systematically administered; however for topical PDT this is no longer a valid assumption. Topical application and subsequent diffusion of the prodrug results in an inhomogeneous distribu...

Top quark-antiquark (tt̄) pairs will be produced copiously at the Tevatron collider and in huge numbers at the LHC. This will make possible detailed investigations of the properties and interactions of this quark flavor. The analysis and interpretation of future data requires precise predictions of the hadronic production of tt̄ pairs and of their subsequent decays. In this talk the reactions pp̄,...

A computer-implemented neurofunctional model of speech production is introduced, which is capable of articulating vowels, VC-, and CV-syllables (C = voiced plosives; V = vowels). It will be shown in this paper that this production model is capable of simulating basic effects of auditory and audio-visual speech perception like (i) categorical perception of consonants and vowels and (ii) the McGu...

A 3D biomechanical finite element model of the face is presented. Muscles are represented by piecewise uniaxial tension cable elements linking the insertion points. Such insertion points are specific entities differing from nodes of the finite element mesh, which makes possible to change either the mesh or the muscle implementation totally independently of each other. Lip/teeth and upper lip/lo...
