Bérard Serge Haddad Interrupt Timed Automata : A Step Further Research Report LSV - 09 - 01 January 2009

In this work, we introduce the class of Interrupt Timed Automata (ITA), which are well suited to the description of multi-task systems with interruptions in a single processor environment. This model is a subclass of hybrid automata. While reachability is undecidable for hybrid automata we show that in ITA the reachability problem is decidable. More precisely we show that the untimed language o...

The goal of this article is to report one case of spontaneous bilateral lumbar Petit's ...

Profile of Christine Petit

Over the last 20 years, geneticist and neurobiologist Christine Petit has written the canticle of the cochlea from scratch, revealing the long-shrouded machinery of the auditory system molecule by molecule. Along the way, she has identified more than 20 genes responsible for hearing impairments, with each of these cochlear deficits accounting for the observed sensory impairment, a succinct stor...
