... processivity. Materials and methods All mathematical analysis and numerical fitting were per- formed using the software package Mathematica 7.0 (Wol- fram Research, Inc. Champaign, IL, USA). The substrate ... supports the cur- rent explanation of the double exponential slowdown. In the last section, we show two examples of how the analysis of the kinetic parameters may el...

... creates a reasonable alignment of the labelled data from which multigram counts can be obtained. The labelled data is a small list of transliteration pairs. Therefore we use the unlabelled data ... Russian/English data. In future work, we plan to adapt our approach to language pairs where one language is alphabetic and the other language is non-alphabetic such as En- glish/Jap...

Up to now there are few data available on the fate of an allergen after ... The radioactivity decreased with time and at 48 h the radioactivity detected in lung was approximately of the same intensity as that of the kidney cortex. Sepa...
