De la clinique du transsexualisme à la clinique du VIH : la catégorisation des sexualités transmasculines au prisme des expériences vécues
No full textInternational audienceLa clinique du transsexualisme a catégorisé les personnes transmasculines (PTM) comme hétérosexuelles. Cette vision a été adoptée dans le cadre de la lutte contre le VIH, influençant la manière de considérer les PTM en matière de prévention. Dans ce contexte, notre article interroge comment ces catégorisations ont affecté les parcours sexuels des PTM, leur accueil dans les services de prévention du VIH, et comment les mobilisations en santé communautaire ont œuvré à combler les lacunes induites. À partir d’une analyse thématique de 13 entretiens et de la littérature communautaire en santé, nous montrons, à rebours de la conception médicale dominante, l’existence d’une pluralité des parcours. Premièrement, pour les individus ayant vécu une hétérosexualité pré-transition, leur orientation sexuelle complique la reconnaissance de soi comme étant trans et nécessite un travail de traduction des représentations médicales de la sexualité. Deuxièmement, nous mettons en évidence la persistance d’une conception cisnormative, voire d’un effacement des PTM dans la clinique du VIH qui est à l’origine de discriminations, d’un sentiment d’illégitimité dans l’accès à la prévention et d’un éloignement des PTM de celle-ci. Enfin, nous montrons que les communautés trans créent des outils de prévention alternatifs qui prennent en compte la diversité des anatomies et de leurs pratiques, mais qu’une forme de « maximisation de la protection » y est présentée et n’est pas considérée comme applicable à leurs pratiques concrètes par une partie de la communauté transmasculine
From Mechanics to Electronics: Influence of ALD Interlayers on the Multiaxial Electro‐Mechanical Behavior of Metal–Oxide Bilayers
No full textInternational audienceThe applicability of metal-polymer thin films in flexible electronics and space applications is fundamentally limited by the trade-off between mechanical and functional performance. This study shows how atomic layer deposited (ALD) amorphous AlO x H y interlayers (0-25 nm) directly control the electro-mechanical functionality of sputter-deposited aluminum films on polyimide substrates. Using uni-and equi-biaxial tensile testing with in situ XRD and electrical resistance measurements, it is demonstrated that interlayer thickness determines both deformation mechanisms and electrical strain limits. Adding an ALD layer between the polymer substrate and the metal thin film significantly improves the deformability of the system. While a single ALD cycle enhances ductility, surprisingly a 1 nm AlO x H y interlayer causes early electrical failure. Optimal performance-improved ductility, delayed cracking, and maintained electrical conductivity under large deformation-is achieved at 5-10 nm interlayer thickness. Beyond this range, embrittlement causes early electrical failure through oxide-initiated cracking. The work establishes quantitative design rules linking the nanoscale interface structure to macroscale electro-mechanical performance, enabling flexible electronics with tailored mechanical properties and enhanced electrical functionality. These findings provide a direct pathway from fundamental interface engineering to high-performance flexible devices operating under multi-axial deformation.</div
Atomic Layer-Deposited Interlayers for Robust Metal–Polymer Interfaces
No full textInternational audienceThe development of materials for flexible electronics and space applications critically depends on the mechanical integrity of metal thin films deposited on polymer substrates. However, film cracking and interfacial delamination at the metal–polymer interface limit the performance significantly. In this work, we demonstrate enhanced adhesion and electromechanical properties of magnetron-sputtered aluminum films on polyimide substrates through the introduction of an amorphous AlOxHy interlayer deposited via atomic layer deposition (ALD). Employing in situ X-ray diffraction and electrical resistance measurements during uniaxial and equi-biaxial tensile testing, we reveal that our integrated ALD–PVD approach yields an up-to-3-fold increase in both the crack onset and electronic failure strains and doubles the adhesion energy of the system. The AlOxHy interlayer alters interface-driven deformation mechanisms from absorbing to blocking dislocations at the interface. The strengthened metal–polymer interface, in turn, improves electromechanical stability at expanded strain ranges, resulting in shorter and more angled cracks in the metal film. This enhanced strain tolerance opens up alternative pathways for the development of flexible thin film devices that can conform to complex curved surfaces and withstand deformation while maintaining their functional properties

Formal models are magic
No full textInternational audienceIn this work, we investigate a variant of the Four Glasses Puzzle (FGP) through the lens of formal verification.Although the puzzle appears to be unsolvable at first glance, formal verification enables the discovery of a correct solution. We demonstrate how the model can be constructed and reduced through progressive abstractions, ultimately yielding a concise and comprehensible model that captures all possible puzzle configurations. This last model is easy to understand, even for non-specialists. Finally, by analysing the strategic capabilities of the player, we present a solution to the puzzle
