Tumeur de Frantz: deux nouveaux cas

A travers cet article, nous détaillons les caractéristiques clinico-pathologiques et discutons l'histogenèse de la tumeur de Frantz. Deux patients opérés pour tumeur de Frantz. Ils ont eu un traitement chirurgical seul. L'étude morphologique était couplée à un examen immuno-histochimique (IHC) utilisant les anticorps anti CD10, antivimentine, anti-énolase neuronale spécifique (NSE), anti-synapt...

NEW HORIZONS New horizons in osteoarthritis

Osteoarthritis (OA) is the most common type of arthritis worldwide and rapidly increasing with ageing populations. It is a major source of pain and disability for individuals and economic burden for health economies. Modern imaging, in particular magnetic resonance imaging (MRI), has helped us to understand that OA is a dynamic remodelling process involving all the structures within the joint. ...

Quelques résultats nouveaux sur les méthodes de projection

We revisit fractional step projection methods for solving the Navier–Stokes equations. We study a variant of pressure-correction methods and introduce a new class of velocitycorrection methods. We prove stability and O(δt) convergence in the L norm of the velocity for both variants. We also prove O(δt) convergence in the H norm of the velocity and the L norm of the pressure. We show that the ne...

Mesurer la proximité entre corpus par de nouveaux méta-descripteurs

Given the number of existing classification algorithms, finding the most appropriate for classifying a new corpus is a difficult task. Meta-classification appears today very useful to help to determine, by using past experiences, what should be the most suitable algorithm compared to our corpus. The underlying idea is that "if an algorithm was particularly suitable for a corpus, it should have ...
