In this paper a performance analysis of the CRMA medium access protocol is presented The CRMA Cyclic Reservation Multiple Access scheme is proposed as an access mechanism for high speed LANs and MANs An approximate computational method is derived to obtain the distribution functions of performance measures of interest like the medium access delay and the packet transfer time The analysis is don...

Beta-1,2-linked mannosides (beta-Mans) are believed to contribute to Candida albicans virulence. The presence of beta-Mans has been chemically established for two molecules (phosphopeptidomannan [PPM] and phospholipomannan) that are noncovalently linked to the cell wall, where they correspond to specific epitopes. However, a large number of cell wall mannoproteins (CWMPs) also express beta-Man ...

The widely held layman’s perception of nature as a collection of animals operating against a static green background of plants is a serious misunderstanding of the complexity and dynamics of the plant biodiversity. Plants fulfill all functions that superficially only seem reserved for animals including movement, communication, and defense. For the latter purposes, plants have developed intricat...

This study follows 66 young French men and women over a 6-year period. Various aspects of their transition to adult life (education, jobs, starting to live as a couple, etc.) were monitored during the three waves of survey. A detailed study of the subjects’ networks was performed during each wave. The networks change considerably between one wave and the next. The personal network appears to be...

The demand and growth for published research in the field of multiple sclerosis (MS) has increased exponentially over the last few years. The primary aim of the Multiple Sclerosis Journal (MSJ) has always been to reflect the excellent work of the ever-expanding and diverse clinical and research field of MS, and this role will now be shared by MSJ’s companion journal MSJ Experimental, Translatio...

In this article we present an approach for tackling three important aspects of text normalization: sentence boundary disambiguation, disambiguation of capitalized words in positions where capitalization is expected, and identification of abbreviations. As opposed to the two dominant techniques of computing statistics or writing specialized grammars, our document-centered approach works by consi...
