Les cétacés vus par le droit
No full textInternational audienceFrom mythical monsters to constitutional figures, from the pools of Marineland to the waters of the Far North, cetaceans traverse the world. But can they traverse the world of law?This collective volume, stemming from a conference held at Université Côte d'Azur, brings together legal scholars from a wide range of specializations around a question as singular as it is urgent: what place does the law afford to cetaceans? From the legendary imaginaries that surround them to their captivity in zoological parks, from hunting in the Baltic Sea to accidental bycatch in the Bay of Biscay, the contributions gathered here explore legal history, administrative law, international law, constitutional law, environmental law, civil law, comparative law, and beyond.Through these analyses, an unprecedented vision of the relationship between humans and these animals emerges, at the crossroads of species conservation and the social representations that shape our norms.A volume for all those who care about the future of law in the face of living beings.This work was supported by the French government through the France 2030 investment plan managed by the National Research Agency (ANR), as part of the Initiative of Excellence Université Côte d’Azur under reference number ANR- 15-IDEX-01
Fast generic method for force gradient evaluation and data averaging in force spectroscopy techniques
No full textForce spectroscopy enables the experimental study of intermolecular and surface forces from molecular biology to hard material science, by measuring the interaction force versus the distance between the surfaces, called the separation. However, analyzing large datasets remains challenging. Here, we introduce a robust and fast method leveraging separation histograms to evaluate force gradients and average force profiles in force spectroscopy data. In experiments with constant driving velocity, an affine relationship between the separation histogram and the force gradient is demonstrated, enabling the reconstruction of forceseparation profiles with even spatial resolution and reduced noise. Additionally, two efficient averaging schemes are proposed, based on the cumulative separation histogram of a dataset and outperforming a conventional interpolation method. The procedures are illustrated with data obtained at the interface between an ionic liquid and a solid substrate by Atomic Force Microscopy, but are generic to all kinds of force spectroscopy techniques and systems

High quality-factor terahertz phonon-polaritons in layered lead iodide
No full textInternational audienceWhile hyperbolic phonon-polaritons in van der Waals materials such as h-BN and α-MoO3 have driven major advances in mid-infrared (IR) nanophotonics, further progress at longer THz wavelengths has been hampered due to material limitations and experimental challenges. Here, we report the discovery of long-lived hyperbolic phonon-polaritons in the deep THz range in layered PbI2. Using room-temperature scattering-type scanning near-field optical microscopy, we achieved real-space imaging and broadband spectral analysis of PbI2 2D crystals transferred onto different substrates with high near-field amplitude contrast and good agreement with theoretical models. Our measurements revealed an experimental figure-of-merit related to the propagating efficiency of the polaritons above 15—on par with state-of-the-art mid-IR benchmarks—and extreme field confinement of 264 for a 144 nm-thick flake, which can exceed 300 in slightly thinner samples. These findings demonstrate that PbI2 combines strong anisotropy, low losses, and extreme mode confinement, making it a compelling candidate for deep-THz nanophotonic applications
Planar pulsating traveling wave solutions of non-cooperative Fisher--KPP systems in space-time periodic media
No full textInternational audienceNon-cooperative Fisher-KPP systems with space-time periodic coefficients are motivated for instance by models for structured populations evolving in periodic environments. This paper is concerned with entire solutions describing the invasion of open space by a persistent population at constant speed. These solutions are important in the understanding of long-time behaviors for the Cauchy problem. Adapting methods developed for scalar equations satisfying the comparison principle as well as methods developed for systems with homogeneous coefficients, we prove, in each spatial direction, the existence of a critical speed such that: there exists no almost planar generalized transition waves with a smaller speed; if the direction is rational, each rational speed not smaller than the critical speed is the speed of a planar pulsating traveling wave with time and transverse space periodicity; if the coefficients are homogeneous in space, each speed not smaller than the critical speed is the speed of a planar pulsating traveling wave with time periodicity

Validation du simulateur ICI de propagation d'épidémies à l'aide des données publiques recueillies pendant la première vague de la pandémie de COVID-19
No full textCe rapport a pour premier objectif de présenter le simulateur ICI de propagation d'épidémies fondé sur des jumeaux numériques de territoires géographiques,de populations synthétiques statistiquement conformes aux populations réelles, et à la simulation numérique des agendas horaires et des interactionssociales des individus, ainsi que des contaminations entre individus. Par méthode de Monte-Carlo ICI fournit des informations statistiques précises, différenciéespar zones géographiques et par catégories de population, sur les évolutions d'épidémies. Ces informations permettent de comparer quantitativement les impacts attendus de politiques sanitaires variées.Le second objectif est de dresser le bilan de nos tests sur la capacité d’ICI à reproduire quantitativement la dynamique épidémiologique et hospitalière observée lors de la première vague de Covid-19 à Paris, et d'analyser les capacités et les limites d'ICI pour des analyses contrefactuelles. Nos résultats montrent que d'ores et déjà ICI est un outil numérique opérationnel d'aide à la décision préalable aux interventions publiques contre les épidémies futures, prêt à être déployé sur des territoires multiples et pour des types variés d'épidémies
