This paper considers gossiping among mobile agents in graphs: agents move on the graph and have to disseminate their initial information to every other agent. We focus on self-stabilizing solutions for the gossip problem, where agents may start from arbitrary locations in arbitrary states. Self-stabilization requires (some of the) participating agents to keep moving forever, hinting at maximizi...

One of the more interesting advances in transportation over the past decade is the introduction of intelligent transportation systems. Of particular interest is the flurry of activity directed at developing advanced traveler information systems (ATISs), especially systems that provide in-vehicle navigation assistance to drivers. These systems are designed to “acquire, analyze, communicate, and ...

Le papillome inversé est une tumeur bénigne naso-sinusienne rare, marquée par une forte agressivité locale, un taux élevé de récidive après chirurgie et un risque imprévisible d'association à un carcinome épidermoïde. Il s'agit d'une étude rétrospective de 22 cas de papillome inversé, colligés entre janvier 2000 et décembre 2012 au service d'oto-rhino-laryngologie et chirurgie cervico-faciale d...

We propose a bio-inspired feedforward spiking network modeling two brain areas dedicated to motion (V1 and MT), and we show how the spiking output can be exploited in a computer vision application: action recognition. In order to analyze spike trains, we consider two characteristics of the neural code: mean firing rate of each neuron and synchrony between neurons. Interestingly, we show that th...

In this study we used dendrochronology to reconstruct the history of eastern spruce budworm (Choristoneura fumiferana (Clem.)) outbreaks over the last 450 years in the Bas-Saint-Laurent region of southeastern Quebec. In total, 260 tree cores were sampled from 204 beams in seven historic buildings and 12 trees in a virgin forest stand. Eight previously documented outbreaks (1975–1992, 1947–1958,...
