Développement durable de l'aquaculture : coordination des acteurs et action publique.

Dans un contexte marqué par la multiplication, l'intensification des conflits d'usage naissant de l'occupation économique de biens environnementaux et l'objectif de développement durable qui se manifeste notamment dans les plans de développement à l'échelon régional, ce texte aborde la question du développement de l'aquaculture en Corse. Il s'agit plus particulièrement de mettre en relation le cadre de l'action publique et l'initiative privée, tout en tenant compte de la dimension écologique du problème posé, ce qui requiert d'emblée la mise en place d'une réflexion de nature pluridisciplinaire en vue de proposer un système d'aide à la décision pour un acteur public. L'approche développée s'articule autour de la production d'une carte d'aptitude du littoral à l'implantation de nouvelles fermes qui vise à repérer les sites potentiels retenus tant pour leur capacité à favoriser une production de qualité que pour leur faible potentiel polémologène. Incorporant d'emblée les principales dimensions de la problématique soulevée (biologique, juridique, sociale et économique), le texte insiste également sur les enjeux liés au processus d'appropriation d'un outil par les acteurs et la manière dont la règle modèle la coordination entre agents publics et privés qui l'ont implicitement retenu comme référent de la mise en œuvre d'un plan de développement durable de la filière aquacole.aquaculture, conflits d'usage, aménagement du territoire, Corse

The Role of Hedgehog Signaling During Hemipene Development in Anolis sagrei

This project\u27s goal was to identify the role of Hedgehog signaling during hemipene development in the lizards Anolis sagrei. Hemepenes are the paired genitalia of squamates, lizards and snakes. When compared to mammals, there little known about the details of lizard genital development. Based on prior observations in mammals, we hypothesized that Sonic hedgehog (Shh) contributes to the development of hemipenes. We knocked down Hedgehog signaling during hemipene patterning to assess the function of Shh during hemipene development. Preliminary data demonstrate that Shh is critical for hemipene patterning in lizards

Restauração de dentes endodonciados: revisão narrativa sobre as opções reabilitadoras

A restauração dos dentes endodonciados representa um grande desafio para os médicos dentistas pois estes dentes apresentam alterações estruturais e biomecânicas com consequente diminuição da sua resistência. A ponderação entre a resistência do dente e a retenção da restauração é importante na decisão clínica da melhor forma de reabilitá-lo. A existência do efeito de ferrule é um factor essencial e preditor de bom prognóstico a longo prazo. Será importante a avaliação de cada situação do ponto de vista periodontal, endodôntico e prostodôntico. A evolução das técnicas adesivas, potencia a diminuição do uso de coroas de recobrimento total retidas através de espigões, e o aumento das reabilitações endocrown, com uma ancoragem intracamara pulpar. Nas situações de coroas clínicas curtas, ou com desgastes com perda de dimensão vertical, ou casos de anatomia radicular atípica, as endocrowns parecem ser a opção ideal. Os estudos publicados sobre o seu desempenho clínico a longo prazo são ainda insuficientes para comprovar a sua eficácia. Este trabalho visa a realização de uma revisão narrativa da informação científica capaz de suportar a evidência clínica das vária sopções de reabilitação de dentes endodonciados. Para tal foi efectuada uma pesquisa na PubMed, B-On com as palavras chave descritas abaixo, e com restrição temporal (2000-21) e linguística (Inglês, francês e português).The restoration of endodontically treated teeth represents a great challenge for dentists because they present structural and biomechanical changes with consequent decrease in their resistance. The balance between tooth resistance and restoration is important in deciding on the best way to rehabilitate it. The existence of the ferrule effect is an essential factor of good long-term prognosis. It will be important to evaluate each situation from the periodontic, endodontic, and prosthodontic point of view. The evolution of adhesive techniques potentiates the decrease in the use of total covering crowns retained through posts, and the increase of endocrown rehabilitations, with an anchorage in the internal portion of the pulp chamber. In situations of short clinical crowns, with loss of vertical size, or cases of atypical root anatomy, the endocrowns seem to be the ideal option. However, published studies on its long-term clinical performance are, insufficient to prove its effectiveness. This work aims to conduct a narrative review of scientific information capable of supporting the clinical evidence of various rehabilitation options of endodontically treated teeth. For that purpose, a search was carried out in PubMed, B-On with the keywords described below, and with temporal (2000-21) and linguistic restriction (English, French and Portuguese)

Prosody for Intuitive Robotic Interface Design: It's Not What You Said, It's How You Said It

In this paper, we investigate the use of 'prosody' (the musical elements of speech) as a communicative signal for intuitive human-robot interaction interfaces. Our approach, rooted in Research through Design (RtD), examines the application of prosody in directing a quadruped robot navigation. We involved ten team members in an experiment to command a robot through an obstacle course using natural interaction. A human operator, serving as the robot's sensory and processing proxy, translated human communication into a basic set of navigation commands, effectively simulating an intuitive interface. During our analysis of interaction videos, when lexical and visual cues proved insufficient for accurate command interpretation, we turned to non-verbal auditory cues. Qualitative evidence suggests that participants intuitively relied on prosody to control robot navigation. We highlight specific distinct prosodic constructs that emerged from this preliminary exploration and discuss their pragmatic functions. This work contributes a discussion on the broader potential of prosody as a multifunctional communicative signal for designing future intuitive robotic interfaces, enabling lifelong learning and personalization in human-robot interaction.Comment: This paper was accepted at the Lifelong Learning and Personalization in Long-Term Human-Robot Interaction (LEAP-HRI) workshop at ACM/IEEE International Conference on Human Robot Interaction (HRI) 202

The capabilities of the software prototype are illustrated in application to the shielding of the X-ray detectors of the eROSITA telescope on the upcoming Spectrum-X-Gamma space mission.Comment: To be published in the Proceedings of the CHEP (Computing in High Energy Physics) 2009 conferenc

Learning Agile Soccer Skills for a Bipedal Robot with Deep Reinforcement Learning

We investigate whether Deep Reinforcement Learning (Deep RL) is able to synthesize sophisticated and safe movement skills for a low-cost, miniature humanoid robot that can be composed into complex behavioral strategies in dynamic environments. We used Deep RL to train a humanoid robot with 20 actuated joints to play a simplified one-versus-one (1v1) soccer game. We first trained individual skills in isolation and then composed those skills end-to-end in a self-play setting. The resulting policy exhibits robust and dynamic movement skills such as rapid fall recovery, walking, turning, kicking and more; and transitions between them in a smooth, stable, and efficient manner - well beyond what is intuitively expected from the robot. The agents also developed a basic strategic understanding of the game, and learned, for instance, to anticipate ball movements and to block opponent shots. The full range of behaviors emerged from a small set of simple rewards. Our agents were trained in simulation and transferred to real robots zero-shot. We found that a combination of sufficiently high-frequency control, targeted dynamics randomization, and perturbations during training in simulation enabled good-quality transfer, despite significant unmodeled effects and variations across robot instances. Although the robots are inherently fragile, minor hardware modifications together with basic regularization of the behavior during training led the robots to learn safe and effective movements while still performing in a dynamic and agile way. Indeed, even though the agents were optimized for scoring, in experiments they walked 156% faster, took 63% less time to get up, and kicked 24% faster than a scripted baseline, while efficiently combining the skills to achieve the longer term objectives. Examples of the emergent behaviors and full 1v1 matches are available on the supplementary website.Comment: Project website: https://sites.google.com/view/op3-socce
