Comtesse puis duchesse d’Angoulême, Louise de Savoie (1476-1531) est l’une des personnalités les plus influentes de la première Modernité européenne. Elle n’est pas seulement la mère de deux enfants illustres, Marguerite, future reine de Navarre, et François, futur François Ier, elle est aussi la sœur de Philibert II le Beau, duc de Savoie. Une fois son fils monté sur le trône de France, Louise domine le Conseil et assure, à deux reprises, la régence du royaume. Son action concerne encore les arts et les lettres : amatrice d’objets d’art et bibliophile avertie, elle demande à Léonard de Vinci d’imaginer une ville et un palais neuf à Romorantin, participant de la sorte à la diffusion en France des idées et des formes venues d’Italie. Curieusement, alors que son influence fut considérable, Louise de Savoie n’a pas fait l’objet d’une monographie récente (un ouvrage collectif à son propos paraîtra toutefois en 2015). Son emblématique n’a plus été analysé depuis les travaux d’Anne-Marie Lecocq (1987), qui s’était essentiellement concentrée sur les signes présents dans les livres qu’elle commanda pour soutenir l’éducation de ses enfants. À l’occasion de cette communication – prolongeant ainsi une recherche entreprise avec Pierre-Gilles Girault – nous voudrions revenir sur le discours héraldique de Louise de Savoie, en explicitant l’une de ses devises favorites, la cordelière. Pour la mère de François Ier, la corde à plusieurs nœuds revêt plusieurs significations. D’abord, puisqu’elle se compose de nœuds de Savoie, un emblème largement diffusé au début du XVIe siècle, notamment sous l’influence de Philibert II le Beau et Marguerite d’Autriche, elle souligne l’appartenance de la dame à la maison de Savoie. Ensuite, et ce de façon inédite au sein de la maison de Savoie, la cordelière de Louise associe nœuds de Savoie et cordon franciscain, une référence que nous proposons d’expliquer non pas uniquement, comme on le fait traditionnellement, par les liens prétenduement étroits qui reliaient la mère de François Ier avec l’ordre des Franciscains. Pour Louise, il s’agit sans doute aussi de se situer dans la lignée d’Anne de Bretagne, à laquelle la cordelière est indéniablement liée. [less ▲]

Durant cette communication, à la suite des travaux d'Anne-Marie Lecocq (1987), nous sommes revenus sur le discours héraldique de la comtesse et duchesse d'Angoulême, Louise de Savoie, l'influente mère de François Ier. Nous avons présenté et explicité ses devises favorites, à savoir la cordelière, qui évoque autant le nœud de Savoie que la cordelière franciscaine, le vol, sans doute choisi puisque l’aile évoque le L de Louise par homophonie, le bouquet de lis ou le cygne « navré », mais aussi les écus et les monogrammes qui lui sont associés et qui ponctuent enluminures, tapisseries, bas-reliefs et éléments sculptés de l’architecture. Notre intention a été de montrer d’une part comment Louise de Savoie manifeste, par l’intermédiaire de ces signes emblématiques, son identité et son pouvoir, d’autre part comment elle construit, par leur biais, un patrimoine, mental, susceptible de renforcer son clan et ses héritiers.

Background: Automatic motor inhibition is an important and adaptive process through which an activated motor plan is suppressed if the movement is not intended to be executed. Neuronal networks are characterized by oscillatory activity. In the brain, a large variety of rhythms have been described that differ in their frequency, origin and reactivity to changes in task demands. Recent studies have demonstrated that active cortical networks are susceptible to weak sinusoidal perturbations of exogenous electric fields. Objective/Hypothesis: The aim of this study was to investigate the frequency-specific effect of transcranial alternate current stimulation (tACS) over the automatic control of movement in healthy volunteers. We hypothesized that applying two different tACS frequencies during a visuo-motor task would result in different behavioural effects and in diverse modulation of cortical excitability. Methods: In this study we used tACS to interact non-invasively with the ongoing task-related oscillatory activity. Stimulation was delivered at alpha (10 Hz) and beta (20 Hz) frequency over the supplementary motor area and the primary motor cortex (SMA-M1) connections, which are part of the BG-cortical motor loop, during the execution of the subliminal masked prime task. We measured the effects on task performance and on motor cortex corticospinal excitability by means of motor evoked potentials (MEPs) evoked by transcranial magnetic stimulation (TMS). Results: Results indicate a specific effect of 10 and 20-Hz tACS on functional inhibition in the SMA-M1 circuit. Behaviorally there is an interference in task-related automatic inhibition: 10 Hz tACS reduced the automatic inhibition. In contrast 20 Hz tACS increased the automatic inhibition. At a neurophysiological level there is a modulation in excitability of M1: 20 Hz tACS reduced MEP amplitudes, whereas there was no change after 10 Hz tACS. Conclusion(s): The current study provides novel evidence that automatic mechanisms of motor behaviour can be modulated by imposing synchronized electrical oscillatory activity upon motor cortical regions. Our study has important implications for cognitive neuroscience studies suggesting that the use tACS might offer the possibility to demonstrate a causal link between endogenous brain oscillations, specific exogenous alternate current frequencies and specific cognitive processes.

Echinoids are common members of Antarctic zoobenthos, and different groups can show important trophic diversity. As part of the ANT-XXIX/3 cruise of RV Polarstern, trophic plasticity of sea urchins was studied in three neighbouring regions (Drake Passage, Bransfield Strait and Weddell Sea) featuring several depth-related habitats offering different trophic environments to benthic consumers. Three families with contrasting feeding habits (Cidaridae, Echinidae and Schizasteridae) were studied. Gut content examination and stable isotopes ratios of C and N suggest that each of the studied families showed a different response to variation in environmental and food conditions. Schizasteridae trophic plasticity was low, and these sea urchins were bulk sediment feeders relying on sediment-associated organic matter in all regions and/or depth-related habitats. Cidaridae consumed the most animal-derived material. Their diet varied according to the considered area, as sea urchins from Bransfield Strait relied mostly on living and/or dead animal material, while specimens from Weddell Sea fed on a mixture of dead animal material and other detritus. Echinidae also showed important trophic plasticity. They fed on various detrital items in Bransfield Strait, and selectivity of ingested material varied across depth-related habitats. In Weddell Sea, stable isotopes revealed that they mostly relied on highly 13C-enriched food items, presumably microbially-reworked benthic detritus. The differences in adaptive strategies could lead to family-specific responses of Antarctic echinoids to environmental and food-related changes. [less ▲]

Video games have become more and more complex over the past decades. Today, players wander in visually and option- rich environments, and each choice they make, at any given time, can have a combinatorial number of consequences. However, modern artificial intelligence is still usually hard-coded, and as the game environments become increasingly complex, this hard-coding becomes exponentially difficult. Recent research works started to let video game autonomous agents learn instead of being taught, which makes them more intelligent. This contribution falls under this very perspective, as it aims to develop a framework for the generic design of autonomous agents for large-scale video games. We consider a class of games for which expert knowledge is available to define a state quality function that gives how close an agent is from its objective. The decision making policy is based on a confidence measurement on the growth of the state quality function, computed by a supervised learning classification model. Additionally, no stratagems aiming to reduce the action space are used. As a proof of concept, we tested this simple approach on the collectible card game Hearthstone and obtained encouraging results. [less ▲]

Adding mucus to in vitro fermentation models of the large intestine showed that some genera, namely lactobacilli, are dependent on host-microbiota interactions and that they rely on mucosa layers to increase their activity. This study investigates whether this dependence on mucus is substrate-dependent and to which extend other genera are impacted by the presence of mucus. Inulin and cellulose were fermented in vitro by a fecal inoculum from pig in the presence or not of mucin-beads in order to compare fermentation patterns and bacterial communities. Mucins increased final gas production with inulin and shifted short-chain fatty acids molar ratios (P<0.001). QPCR analyses revealed that Lactobacillus spp. and Bifidobacterium spp. decreased with mucins, but Bacteroides spp. increased when inulin was fermented. A more in-depth community analysis indicated that the mucins increased Proteobacteria (0.55 vs. 0.25 %, P=0.013), Verrucomicrobia (5.25 vs. 0.03 %, P=0.032), Ruminococcaceae, Bacteroidaceae, and Akkermansia spp.. Proteobacteria (5.67 vs. 0.55 %, P<0.001) and Lachnospiraceae (33 vs. 10.4 %) were promoted in the mucuscompared to the broth, while Ruminococcaceae decreased. The introduction of mucins affected many microbial genera and fermentation patterns, but from PCA results, the impact of mucus was independent from the fermentation substrate. [less ▲]

In order to favor electronic conductivity in sodium iron fluorophosphate electrodes for lithium- or sodium-ion batteries, composites of Na2FePO4F with multi-walled carbon nanotubes (CNTs) were prepared by pilot-scale spray drying. Addition of multi-walled CNTs in the solution results in an excellent dispersion of the CNTs within the volume of Na2FePO4F and not only at the surface of the particles. Following a heat treatment at 600°C in argon in order to reach crystallization, X-ray diffraction and ex situ Mössbauer spectroscopy revealed the presence of significant amounts of Fe(III) and maghemite (γ-Fe2O3) in the powder. However, Na2FePO4F/CNTs composites exhibit good electrochemical performance when cycling against lithium, with a discharge capacity of 104mAhg-1 at C/10 rate and 90mAhg-1 at 1C rate. Therefore, operando 57Fe transmission Mössbauer spectroscopy analyses were carried out in order to investigate the evolution of the iron oxidation state during cycling. During the first discharge, all the Fe(III) is reduced to Fe(II), explaining the good electrochemical performance. [less ▲]

This chapter presents the modalities of a system of benchmarking that has been designed with the aim of measuring legal protection against statelessness as provided by citizenship laws and comparing these across countries and regions. The benchmarks focus on seven groups of persons who are at risk of remaining/becoming stateless, including otherwise stateless children born in a country and persons who are at risk of being deprived of citizenship. This chapter discusses not just how and why these benchmarks have been developed but also what lessons can be drawn from their application in Europe and the Americas. [less ▲]
