Réduire la distance psychologique au changement climatique : un levier pour l'adaptation, un frein pour l'atténuation ?
No full textInternational audienceL'émergence récente de groupes scientifiques régionaux sur le climat (e.g., GIEC Normand) fait évoluer les discours climatiques, désormais davantage focalisés sur ses conséquences locales et concrètes. En psychologie, cette stratégie fait écho à l'idée communément admise selon laquelle réduire la distance psychologique au changement climatique favoriserait son atténuation tout comme son adaptation (e.g., van Der Linden et al., 2015). Or, cette stratégie est désormais réévaluée, certains soulignant des effets limités voire contre-productifs de la proximisation du changement climatique (van Valkengoed et al., 2023). En distinguant l'atténuation globale du changement climatique de son adaptation plus locale, la présente étude vise à approfondir cette critique en examinant si proximiser le changement climatique pourrait favoriser des actions d'adaptation au détriment d'actions d'atténuation, moins ancrées localement mais nécessaires pour en limiter l'ampleur.Dans une étude pré-enregistrée (https://osf.io/j6q8v/?view_only=18fb7e230a964bb38060b01c24d87a60) en ligne, 205 Normand·e·s (66.1% femmes, Mage = 31.3, SDage = 17.7) étaient assigné·e·s à une des trois conditions expérimentales (proximale : communication sur les impacts immédiats du changement climatique dans leur département ; distale : impacts différés dans un territoire ultramarin ; contrôle : sans manipulation). En tant que membres d'un conseil municipal fictif, ils·elles étaient ensuite chargé·e·s de distribuer des ressources entre cinq actions d'atténuation, cinq actions d'adaptation et dix actions sans lien avec le climat. Les résultats indiquent que les participant·e·s en conditions proximale et distale attribuent plus de ressources aux actions climatiques que ceux·celles du groupe contrôle, qu'il s'agisse d'atténuation ou d'adaptation. Cependant, aucune différence n'était observée entre les conditions proximale et distale concernant le soutien aux actions d'atténuation versus d'adaptation. Des analyses exploratoires révèlent toutefois un effet modérateur de l'orientation politique, les participant·e·s conservateur·rice·s soutenant davantage les actions d'atténuation en condition proximale et d'adaptation en condition distale. Ces résultats seront discutés en référence aux dynamiques intergroupes au cœur des enjeux climatiques

Benchmark of Diffusion and Flow Matching Models for Unconditional Protein Structure Design
No full textInternational audienceWith the widespread application of deep neural networks, generative models, especially diffusion models and flow matching models, for protein design have experienced explosive growth. However, there remains a lack of comprehensive evaluation frameworks to systematically assess the performance of these models. This study addresses this gap by focusing on the task of designing unconditional protein structures, benchmarking seven state-of-the-art (SOTA) models in four distinct dimensions: structural validity, diversity, novelty, and computational efficiency. This work provides standardized metrics and baseline benchmarks to guide future research and innovation in protein design

Charging of Ligand-Protected Gold Nanoparticles in Electrospray Ionization: Probing Ligand Bond Strength by Charge Detection Mass Spectrometry
No full textInternational audienceThe ionization of large, megadalton (MDa) and gigadalton (GDa), nanoparticles leading to their mass spectrometric analysis has been an interesting challenge in the past decades. In this work, the charging behavior of 20 nm sized gold nanoparticles (AuNPs) protected with 11-mercaptoundecyl-N,N,N-trimethylammonium bromide (MUTAB) ligands of ∼50 MDa was studied by using Charge Detection Mass Spectrometry (CDMS) interfaced with electrospray ionization. The findings indicate that these nanoparticles can achieve a charging state higher than the Rayleigh limit for a 20 nm solvent droplet. However, citrate-protected 60 nm sized AuNPs of ∼1.3 GDa charge only ∼0.45 times the Rayleigh limit, under identical electrospray conditions. The higher efficiency of charging in Au–MUTAB nanoparticles may be correlated to the higher ligand binding energy of the gold–sulfur interface compared to the gold–citrate interface. This work showcases the impact of ligand selection on the electrostatic behavior, stability, and charging of nanoparticles in electrospray ionization mass spectrometric applications
Fragmentación, adaptación y experiencia migrante en Desierto Sonoro (2019) de Valeria Luiselli
No full textNúm. 31, julio - diciembre2025, e568.International audienceValeria Luiselli is characterised by a compact oeuvre in which the neo-fantastical and the absurd cohabitate within intimate and experiential constructions. It is also an erudite oeuvre, where texts are at once novels and essays, and one that feeds on itself as well as on an expansive tradition. This work will analyse the construction of Mexican writer Valeria Luiselli's novel Desierto Sonoro as an exercise in marrying fiction and nonfiction, given the novel's continued entanglement with the essay that precedes it, Los niños perdidos, also by Luiselli. We will analyse the imprints of the multiple adaptations, mostly at the level of tropes and archetypal figures, to be found in this novel, as well as the main writerly principles that underwrite the transformation of archival documents into a work of fiction. The chosen textual framework does not imply the exclusion of ideological or political concerns. Rather, this work will aim to demonstrate how the political not only fully belongs to, but is crystallised in the subjective and the sentimental.Valeria Luiselli se caracteriza por una obra compacta en la que cohabitan lo neofantástico y lo absurdo, así como la construcción íntima y experiencial. Se trata también de una obra erudita (novela y ensayo) que se nutre de sí misma y de una tradición ancha y vasta. Este trabajo analiza la construcción novelesca de Desierto Sonoro de la escritora mexicana Valeria Luiselli en tanto ejercicio de fusión entre ficción y dicción, puesto que la novela mantiene una relación intrínseca con el ensayo que la precede, Los niños perdidos, de la misma autora. Se analizarán las huellas, en esta novela, de las múltiples adaptaciones, esencialmente a nivel de tropos y figuras, así como los principales mecanismos escriturales que marcan el proceso de transformación del archivo documental en obra de ficción. La óptica textualista privilegiada no implicará descartarlo ideológico o político. Al contrario, se buscará demostrar la manera en que lo político tiene entera cabida o se cristaliza a través de lo subjetivo y lo sentimental

Multiscale Mapping of the Salt Marshes Using Sentinel-2, Dove and UAV Imagery in the Bay of Mont-Saint-Michel
No full textThe salt marshes, lying at the land-sea temperate interface, furnish a plethora of ecosystems services such as biodiversity niche support, ocean-climate change regulation, ornithology recreo-tourism or plant gathering by hand. They undergo significant worldwide losses due to their conversion into crop fields and to their spatial compression between the rising sea-level and the armoring shoreline. Their monitoring however requires to use a suite of remote sensing sensors to embrace the regional scale while capturing the plant details. This research innovatively adopts a multiscale approach using a cascading spaceborne and airborne process, from the 10-m Sentinel-2, through the 3-m Dove, to the 0.03-m unmanned airborne vehicle (UAV) imageries. The high to very high temporal resolution of the Sentinel-2 and Dove enabled to cover twenties and tens of km2 over five and four years, respectively, in the form of normalized difference vegetation index (NDVI) classes, associated with microphytobenthos, low, medium and high salt marsh vegetation, including the opportunistic Elyma genus. The NDVI was then modelled at the UAV scale (a few km2) using a three-layered NN prediction, providing the final near-infrared (NIR), and the intermediate red, green and blue reflectance imageries, calibrated/validated/tested with the Dove reflectance imageries (R2NIR=0.98, R2red=0.88, R2green=0.84, and R2blue=0.90). The 100fold increase in pixel size allowed to detect the decimeter-scale objects of the tidal flats and salt marshes, to enlarge the NDVI class ranges, and hold great promise to model other spectral bands at the UAV scale for further deeply enhancing the salt marsh mapping
Steady state large deviations for one-dimensional, symmetric exclusion processes in weak contact with reservoirs
No full textInternational audienceConsider the symmetric exclusion process evolving on an interval and weakly interacting at the end-points with reservoirs. Denote by its dynamical large deviations functional and by the associated quasi-potential, defined as V(\gamma) = \inf_{T>0} \inf_u I_{[0,T]} (u), where the infimum is carried over all trajectories such that , , and is the stationary density profile. We derive the partial differential equation which describes the evolution of the optimal trajectory, and deduce from this result the formula obtained by Derrida, Hirschberg and Sadhu \cite{DHS2021} for the quasi-potential through the representation of the steady state as a product of matrices
