Nowadays, the understanding of Boolean automata networks dynamics takes an important place in various domains of computer science such as computability, complexity and discrete dynamical systems. Basing ourselves on these specific mathematical objects, in this paper, we make a step further in this understanding by focusing on their cycles, whose necessity in networks is known as the brick of th...

Labor costs are amongst the most important costs for companies in highly developed countries. While manufacturers move their production units en masse to low wage countries, service companies are often tied to their current locations. Unlike production, the service surplus value is often directly related to the place where the service is provided. Moreover, service companies generally require m...

In the course of investigations on the colonial morphology of different strains of mycobacteria,1 their susceptibility to recently isolated bacteriophages2 and physiological properties associated with pathogenicity, it was observed that several strains of BCG in the Olive View culture collection showed some differences from each other by the various technics employed. In order to determine if t...

NEMIA is part of the natural history of chronic lymphatic leukemia. The etiology of the anemia has been attributed to a decreased rate of red cell production’3 and to an increased rate of red cell destruction.49 Prior studies have been based on estimations of ( 1 ) the amount of erythrobbastic tissue found in smears of aspirated bone marrow and in sections of the marrow at autopsy; ( 2 ) the re...

This research work focuses on bringing performances in 3D dislocation dynamics simulation, to run efficiently on modern computers. First of all, we introduce some algorithmic technics, to reduce the complexity in order to target large scale simulations. Second of all, we focus on data structure to take into account both memory hierachie and algorithmic data access. On one side we build this ada...
