Formica lugubris apparaît comme une espèce hautement polycalique dans le Jura suisse et forme des super-colonies. La super-colonie étudiée comprend environ 1200 nids répartis sur 70 hectares. L'étude détaillée de 12 hectares permet de définir 4 types de nids:les nids principaux, secondaires, saisonniers etcommençants, ainsi que trois sortes de voies de communication:les routes de liaisons permanentes visibles sur le terrain, les pistes de liaisons non-permanentes non marquées sur le terrain etles chemins d'approvisionnement permanents marqués dans le terrain. L'auteur présente la phénologie deF. lugubris qui est fortement influencée par le climat de cette région avec une période moyenne d'activité de 150 jours. D'autre part, les premières données sur le régime alimentaire (analyse des proies récoltées par les fourmis) diffèrent considérablement des données connues pour les autres espèces du groupe rufa, notamment par le nombre élevé de pucerons, d'où l'idée d'une régulation des populations de pucerons par les fourmis. Enfin l'auteur aborde le problème de la faible densité de l'avifaune en relation avec les fourmis. Il semble que le climat et les ressources alimentaires conduisent les fourmis àune nouvelle stratégie écologique qui s'exprimerait par la création de super-colonies. Formica lugubris appears as a highly polycalic species in the Swiss Jura and creates super-colonies. The super-colony studied possesses about 1200 nests on about 70 hectares. The detailed study of 12 hectares allows the discrimination of 4 types of nests:the main nests, the secondary nests, the seasonal nests andthe starting nests, as well as 3 types of ant tracks:the constant connection routes visible on the soil, thenon-constant connection tracks not marked on the soil andthe constant foraging routes marked on the soil. The author presents the phenology ofF. lugubris who is strongly influenced by the climate of the region with a mean activity period of about 150 days. On the other hand, the first results about diet (analysis of the preys collected by the ants) differ considerably from the wellknown data for the others species of the rufa group, especially by the high number of aphids, which may be inferred the notion of a regulation of aphids population by the ants. Finally the author approaches the problem of the low density of avifauna in relation to the ants. It seems that climate and food resources lead the ants toa new ecological strategy which would express itself by the creation of super-colonies.

Super- and co-infection with HIV-1 are generally associated with accelerated disease progression. We report on the outcome of super-infection in two HIV-1 infected individuals previously known as elite controllers. Both presented an acute retroviral syndrome following super-infection and showed an immuno-virological progression thereafter. Host genotyping failed to reveal any of the currently recognized protective factors associated with slow disease progression. This report indicates that elite controllers should be informed of the risk of super-infection, and illustrates the complexity of mounting broad anti-HIV immunity.

Although fetal anatomy can be adequately viewed in new multi-slice MR images, many critical limitations remain for quantitative data analysis. To this end, several research groups have recently developed advanced image processing methods, often denoted by super-resolution (SR) techniques, to reconstruct from a set of clinical low-resolution (LR) images, a high-resolution (HR) motion-free volume. It is usually modeled as an inverse problem where the regularization term plays a central role in the reconstruction quality. Literature has been quite attracted by Total Variation energies because of their ability in edge preserving but only standard explicit steepest gradient techniques have been applied for optimization. In a preliminary work, it has been shown that novel fast convex optimization techniques could be successfully applied to design an efficient Total Variation optimization algorithm for the super-resolution problem. In this work, two major contributions are presented. Firstly, we will briefly review the Bayesian and Variational dual formulations of current state-of-the-art methods dedicated to fetal MRI reconstruction. Secondly, we present an extensive quantitative evaluation of our SR algorithm previously introduced on both simulated fetal and real clinical data (with both normal and pathological subjects). Specifically, we study the robustness of regularization terms in front of residual registration errors and we also present a novel strategy for automatically select the weight of the regularization as regards the data fidelity term. Our results show that our TV implementation is highly robust in front of motion artifacts and that it offers the best trade-off between speed and accuracy for fetal MRI recovery as in comparison with state-of-the art methods.
