A Graph based architectural (re)configuration language
For several different reasons, such as changes in the business or technological environment, the configuration of a system may need to evolve during the execution. Support for such evolution can be conceived in terms of a language for specifying the dynamic reconfiguration of systems. In this paper, continuing our work on the development of a formal platform for architectural design, we present a high-level language to describe architectures and for operating changes over a configuration (i.e., an architecture instance), such as adding, removing or substituting components or interconnections. The language follows an imperative style and builds on a semantic domain established in previous work. Therein, we model architectures through categorical diagrams and dynamic reconfiguration through algebraic graph rewriting

Emploi de microsatellites pour l'analyse de la diversité génétique des races bovines françaises: premiers résultats
La caractĂ©risation des races bovines françaises a dĂ©butĂ© en utilisant comme principales sources de donnĂ©es des Ă©tudes morphologiques. Progressivement, grĂące Ă lâĂ©volution des techniques dâanalyse de la variabilitĂ© gĂ©nĂ©tique, dâautres critĂšres ont pu ĂȘtre pris en compte. Des donnĂ©es concernant le polymorphisme des groupes sanguins, de certaines protĂ©ines sĂ©riques et des protĂ©ines du lait ont permis de distinguer 4 sous ensembles de races bovines françaises. Cette Ă©tude va ĂȘtre approfondie par une analyse du polymorphisme au niveau de lâADN en utilisant de nouveaux marqueurs plus nombreux et plus polymorphes : les microsatellites. Cet article prĂ©sente la mise en place dâun projet dâĂ©tude du polymorphisme de 20 microsatellites dans 11 races bovines françaises choisies de façon Ă ce que les 4 sous-ensembles soient reprĂ©sentĂ©s. Les premiers rĂ©sultats obtenus sur 6 races (Brune des Alpes (BU), Charolaise (CH), MontbĂ©liarde (MO), Normande (NO), Parthenaise (PA) et Vosgienne (VO) ) avec six locus microsatellites (INRA013, INRA016, INRA035, INRA037, INRA040 et ETH131) sont dĂ©crits. Une rĂ©partition trĂšs diffĂ©rente des frĂ©quences allĂ©liques des microsatellites est observĂ©e dâune population Ă lâautre. Ces rĂ©sultats prĂ©liminaires montrent que les microsatellites peuvent ĂȘtre de bons outils pour ce programme dâanalyse phylogĂ©nique.French cattle breeds were first characterized according to data from morphological studies. Subsequently, technical advances allowed the use of other polymorphic biochemical characters such as blood groups, serum proteins or milk proteins. The different breeds could be classified into 4 subsets. At present, the development of molecular biology techniques has made it possible to analyse polymorphism at the DNA level using microsatellites which are numerous and highly polymorphic. This article presents a study on the polymorphism of 20 microsatellites in 11 French cattle breeds including representatives of the 4 subsets. The first results obtained with 6 cattle breeds (Brune des Alpes (BU), Charolaise (CH), Montb6liarde (MO), Normande (NO), Parthenaise (PA) and Vosgienne (VO)) using 6 microsatellite loci (INRA013, INRA016, INRA035, INRA037, INRA040 and ETH131) are described. Differences were observed in microsatellite allelic frequencies between the different breeds. These prelimary results show that microsatellites are promising tools for phylogenetic studies
