Guillaume Postel (1510-1581) : écrits et influence

International audienceDans cet ouvrage collectif, Paul-Victor Desarbres, Emilie Le Borgne, Tristan Vigliano et Frank Lestringant proposent aux lecteurs de découvrir pour certains ou de redécouvrir pour d’autres, Guillaume Postel, figure à la fois marginale et omniprésente au XVIe siècle. L’objectif de cette entreprise est de réévaluer ce personnage et sa pensée sous un nouveau jour, à travers plusieurs facettes de ses écrits : la concorde et la restitutio, l’étude des langues orientales, la figure du lecteur royal en mathématiques ou du prophète

Traveling the Country: Transportation Challenges and Mobility Management

International audienceTerritorial fragmentation, abrupt mountain reliefs, insular nature, outermost regions, limited land management capacity, and major shortages in crucial infrastructure: There is a longer list of obstacles to movement in post-war Greece. These elements constitute a basis for a bleak scenario further evidenced by a high number of road accidents, acute traffic congestion, and degraded travel conditions. However, it is often ignored that, as compensation, Greece has been able to set up a highly functional bus network, operate and develop effective airport facilities across the country, and maintain active ferry connections with a great many islands, thus securing access to remote places.The country developed around a mobility model centered almost exclusively on the automotive sector. The efficiency of this “automobile pact” system and its ability to serve a strong demand now hardly needs to be demonstrated. However, the post-1974 crisis years generated side effects, especially impacting urban mobility and inter-city connections. Saturation and crumbling infrastructure are required to rethink the whole system, achieve faster transport, and reach environmental sustainability goals.The analysis will focus on the many advances registered these last years in improving mobility, especially through the angle of regional and international passenger traffic. Surprisingly, there seems to be a global slowdown in internal mobility while external travels show positive momentum

RATIONALITY OF EXTENDED UNIPOTENT CHARACTERS

We determine the rationality properties of unipotent characters of finite reductive groups arising as fixed points of disconnected reductive groups under a Frobenius map

Large mercury release from the Greenland Ice Sheet invalidated

International audienceThe major input of mercury (Hg) to the Arctic is normally ascribed to long-range transport of anthropogenic Hg emissions. Recently, alarming concentrations of Hg in meltwater from the Greenland Ice Sheet (GrIS) were reported with bedrock as the proposed source. Reported Hg concentrations were 100 to 1000 times higher than in known freshwater systems of Greenland, calling for independent validation of the extraordinary concentrations and conclusions. Here, we present measurements of Hg at 21 glacial outlets in West Greenland showing that extreme Hg concentrations cannot be reproduced. In contrast, we find that meltwater from below the GrIS is very low in Hg, has minor implications for the global Hg budget, and pose only a very limited risk for local communities and the natural environment of Greenland

La position des études de stabilité dans le cycle de vie des médicaments à l'international

Le médicament, fondé sur la qualité, la sécurité et l'efficacité, est régi par des normes strictes tout au long de son cycle de vie, de la recherche à la distribution. L'AMM, standardisée avec le CTD, est une étape cruciale. Les études de stabilité, intégrées au module 3 du CTD, sont essentielles pour garantir la conformité du médicament aux différentes zones climatiques définies par l'OMS. Exporter des médicaments dans des zones climatiques différentes représente un défi logistique et financier, nécessitant une adaptation des études de stabilité. Ces études, avant ou après l'AMM, assurent une évolution sûre des produits en spécifiant une date et une condition de conservation, garantissant la sécurité des patients. En outre, les études de stabilité peuvent varier en fonction des formes pharmaceutiques et des conditions climatiques, mais suivent un plan chronologique strict dicté par ICH. Elles sont indispensables pour les médicaments princeps et génériques, qu'ils soient destinés à la France ou à d'autres territoires du globe, garantissant ainsi la sécurité des patients

On the thermodynamic limit of two-times measurement entropy production

We provide a justification, via the thermodynamic limit, of the modular formula for entropy production in two-times measurement proposed in [Benoist, Bruneau, Jakšić, Panati and Pillet: arxiv:2310.10582]. We consider the cases of open quantum systems in which all thermal reservoirs are either (discrete) quantum spin systems or free Fermi gases

Mixed responses of ant communities to the eradication of black rats and iceplants on a small Mediterranean island

International audienceEradication of invasive alien species (IAS) is often proposed to restore invaded ecosystems, with information on subsequent ecosystem recovery key to conservation policies. Although ants perform major ecological functions in the ecosystem, their response to IAS eradication has received relatively little monitoring. This study investigated ant response to iceplant (Carpobrotus spp.) and black rat (Rattus rattus) eradications on the small Mediterranean island of Bagaud (Var, France). Ant communities were monitored over a ten-year period, including two years before eradications, at six diferent sites: two invaded by iceplants, two under high rat pressure, and two native vegetation sites without intervention. We found inter-annual variations in ant communities but no before-after eradication trend at both native vegetation and rat eradication sites. However, there was a clear increase in ant species richness and abundance score after the iceplant eradication. A core of common Mediterranean species, including Pheidole pallidula, Messor bouvieri, and Plagiolepis pygmaea, increased their foraging activity after the removal. As xerophilous and thermophilous species they would beneft from the return of native vegetation with possibly warmer and dryer microclimatic conditions, but also from habitat and resource diversifcation. The trend was even stronger on the denser and thicker iceplant eradication patch. Our results emphasize the relevance of implementing ant monitoring to evaluate the efectiveness of such restoration and conservation strategies
