abstract：:Prevention against the weapons of bioterrorists is limited by the multiplicity of agents that could be used. Against smallpox, stocks of the classical vaccine must be prepared, but this vaccine is dangerous and we must look for a new and safer vaccine. A vaccine against anthrax is probably possible relatively soon. On...

abstract：:Plectroctena minor workers have long mandibles that can snap and deliver a sharp blow to intruders or prey, stunning or killing them. Encounters between homocolonial P. minor workers separated for 24 h or 15 days never resulted in snapping, while this behaviour was always noted during encounters between heterocolonial...

abstract：:With an expectation of life at birth of 27 years in the middle of the 18th century, 21% of males reached their 60th birthday with a remaining expectation of life of 12 years. Under the conditions of mortality of 1950, in France, 70 percent could celebrate their 60th birthday, and they had still 15 years (only) to live...

abstract：:We propose to start the analysis of complex systems by systematically identifying the feedback circuits that govern their dynamics. These circuits can be identified without any ambiguity by examining the Jacobian matrix of the system. They provide precious information regarding the number and nature of steady states. ...

abstract：:Sleep disorders have a high prevalence: around 20% of insomniacs, 10% hypersomnolent including 2 to 4% of sleep disordered breathing in the general adult population. The low availability of sleep centres implies the research of alternative recording techniques in the natural setting of the patient. The objective was t...

abstract：:Surgical resection of hepatic tumours is not always possible, since it depends on different factors, among which their location inside the liver functional segments. Alternative techniques consist in local use of chemical or physical agents to destroy the tumour. Radio frequency and cryosurgical ablations are examples...

This fundamental relationship between bone structure and growth dynamics, first assumed by Amprino many decades ago, was quantified in preliminary studies, but never statistically tested. Moreover, the precise typological characters of bone tissue linked to g...

abstract：:Using protein loci and DNA markers, we show by a multilocus genetic analysis that certain populations of the two sympatric mouse species Mus musculus domesticus and Mus spretus show clear signs of partial introgression. Given the sterility of F1 males and the known partial genetic incompatibilities between the genomes...

The nu...
