Plus jamais seul

Virchow ne meurt jamais

Les exostoses représentent la forme la plus fréquente des tumeurs osseuses bénignes, elles peuvent être uniques ou multiples se formant au niveau des métaphyses des os longs avec une prédilection pour le fémur et l'humérus. Elles sont le plus souvent asymptomatiques mais peuvent parfois être révélées par une complication osseuse ou à l'occasion de la compression de tissus mous de voisinage. Les...

Transcatheter aortic valve replacement failure: déjà vu ou jamais vu?

T he past half decade has seen transcatheter aortic valve replacement (TAVR) emerge as the standard of care for inoperable and high-risk patients with severe aortic stenosis: randomized data have demonstrated reduced mortality with TAVR compared with medical therapy or surgery in these respective situations. Accordingly, recent research efforts have reorientated from establishing the short-term...

The Soliton-Stripe Pattern in the Seul-Andelman Membrane ∗†

The Seul-Andelman membrane is a system of two coupled fields: The composition φ of one of the two (A and B) constitutive molecules, and the height profile h of the flexible membrane. The free energy of the system consists of two parts. The first part is the usual GinzburgLandau free energy of φ; the second part is attributed to the bending of the membrane and the coupling of φ to h. The couplin...

Un ordonnancement dynamique de tâches stochastiques sur un seul processeur

We show that a particular dynamic priority given to jobs in a multitasks operating system of computers is a deteriorating jobs or a delaying jobs scheduling. Under some assumptions we also show that it is an index rule. To do this, we present the tool of bandit processes to solve stochastic scheduling problems on a single machine. Résumé. Nous montrons qu’une priorité dynamique particulière all...
