Problems of multiservice network modeling on the basis of hybrid methods – methods of graph theory and queue system are considered in the article. Model NGN-network is presented in the form of exponential Petri net. For calculation of probabilistic and time characteristics of network on the basis of Petri net analytical expression was received. On the basis of this expression calculation of tim...

The use of routine datasets in the evaluation of interventions in clinical trials is increasing. Action to Support Practices Implementing Research Evidence (ASPIRE) is an NIHR Programme aiming to develop and test ways to support general practices in implementing key NICE recommendations. Multifaceted intervention packages have been developed to target four key clinical practice recommendations,...

We h a v e measured the B hadron energy distribution in Z 0 decays using a new technique applied to a sample of inclusive B decays recorded in the SLD experiment at SLAC b e t w een 1996 and 1997. The upgraded CCD vertex detector is used to reconstruct B-decay v ertices with high eeciency and purity, and to provide precise measurements of the kinematic quantities used in this technique. For eac...

discrete chromatin complexes, although there is no eviThe nucleolus was one of the first subnuclear elements dence that it directly contacts DNA. How Sir2 arrives in observed by early microscopists, yet in the centuries the nucleolus and what the broader significance for that since its discovery, ideas about its significance have localization is are open questions that have now been ranged from...
