Prognostic Factors for Free Flap Failure in Head and Neck Reconstruction
No full textInternational audienceBackground The failure rate of free flaps varies from 0.8% to 10.6% in the literature in head and neck reconstruction. The primary objective was to identify prognostic factors for free flap failure. Methods We prospectively included all consecutive free flaps performed between August 2021 and January 2024, and used a multivariate Cox proportional hazard model. Results We included 307 free flaps, performed on 274 patients. Age, cardiovascular risk, radiotherapy history, type of flap, type of arterial anastomosis, and ischemia duration were not statistically linked to the risk of flap failure. In multivariate analysis, a venous anastomosis to the anterior jugular vein or to the superior thyroid vein were associated with an increased risk of flap failure, such as per‐ or postoperative revision of the anastomoses. Conclusions The choice of venous anastomosis, appear to have a greater influence on the success or failure of a microvascularized transfer than patient characteristics

Intelligent Task Offloading in Vehicular Networks: A Deep Reinforcement Learning Perspective
No full textInternational audienceThe proliferation of connected vehicles and the Internet of Things (IoT) has made access to high-quality services increasingly viable. However, the growing number of vehicular applications poses challenges for embedded systems that need to perform tasks efficiently despite network fluctuations. To solve this problem, we have developed a Vehicular Edge Computing (VEC) system with a task offloading algorithm adapted to the Internet of Vehicles (IoV). Our solution uses a four-stage Stackelberg game and a reinforcement learning model. The approach consists of analyzing the vehicle state in real time to determine computational requirements and cost functions, implementing communication methods and cost functions, and using multi-agent reinforcement learning to design an experience-based offloading strategy. Through simulations, our algorithm demonstrates a balanced optimization of time, expense, work vehicle utility and service vehicle utility, while improving the probability of task success under various constraints
La notion de vérité à l’épreuve de l’intelligence artificielle
No full textInternational audienceCan we apply traditional notions of truth and error to the artificial production of statements? Drawing on a tripartition proposed by Umberto Eco, the article questions the contemporary relevance of the criteria of truth used to evaluate human statements. It highlights that artificial statements are neither true nor false in the same way as those produced by humans, which challenges our conception of language. The article identifies the specificity and limitations of automatic language generation, focusing on machines' inability to anchor themselves in reality through perception. It concludes by outlining the potential of mechanical enunciation and introduces "humility"—an attitude, contrasted with the common concept of explainability—that we might adopt toward artificial intelligences.Pouvons-nous appliquer les notions traditionnelles de vérité et d’erreur à la production artificielle d’énoncés? A partir d’une tripartition proposée par Umberto Eco, l’article s’interroge sur la pertinence contemporaine des critères de vérité utilisés pour évaluer les énoncés humains. Il s’agit de remarquer que les énoncés artificiels ne sont pas vrais ou faux comme ceux produits par les humains, ce qui remet en question notre conception du langage. L’article identifie la spécificité et les limites de la génération automatique de langage dans l’incapacité des machines de s’ancrer au réel par le biais de la perception. Il conclut en indiquant les potentialités de l’énonciation mécanique et nomme “humilité,” l’attitude, opposée au concept courant d’explicabilité, que l’on pourrait adopter vis-à-vis des intelligences artificielles
Metropolitan governance as organised anarchy: The case of the Paris region
No full textInternational audienceThe governance of metropolitan areas is, of course, fragmented, messy, and contentious. It involves a multiplicity of individual and collective actors, layered policies, overlapping jurisdictions, bricolage, and gridlock. However, some collective action takes place, some projects are built, and some policies are implemented. This article is part of a body of critical urban governance research that seeks to unpack the non-linear, conflictual, incomplete, and more or less democratic nature of the modes of governance in large metropolitan areas. It builds upon the analysis of policymaking in the Paris region to address this non-linear nature of metropolitan governance. Moving beyond coordination complexity or ungovernability, that mode of governance can be characterised in terms of “organised anarchy”. This is a social territorial world made of loosely coupled organisations, ill-defined or contradictory policy goals, power relations, and sometimes opaque policy processes. We identify four forms of collective action within the organised anarchy that characterises Paris metropolitan governance
