• Sommario/riassunto: La recherche en endocrinologie a été un des points forts de la biologie française au cours des dernières décennies. Elle joue un rôle majeur sur le plan fondamental où, en dehors de son intérêt propre, elle sert de modèle à la compréhension des mécanismes généraux de signalisation. En outre, elle débouche sur certains des problèmes les plus préoccupants de santé publique, donnant lieu à de très importantes approches pharmacologiques et thérapeutiques. L'objet de ce rapport est d'évoquer les plus importants de ces problèmes, situés à l'interface des sciences médicales et des sciences de la société. du point de vue strictement médical, quatre questions se posent avec une acuité croissante : les relations entre hormones et cancers, le traitement substitutif de la ménopause, la contraception hormonale au long terme et l'influence de certaines hormones sur le développement de l'obésité et du diabète de type 2. Un autre sujet important concerne le vieillissement, conçu comme un ensemble complexe de facteurs biologiques, cognitifs, sociaux et finalement sociétaux. Un aspect, plus technique mais également de grande importance, concerne les perturbateurs hormonaux, des produits chimiques qui peuvent modifier de façon indésirable la production de certaines hormones. Un dernier aspect concerne l'utilisation des hormones hors de la médecine, notamment chez les animaux comestibles. L'ambition de ce rapport est de donner l'arrière-plan scientifique permettant de comprendre les mécanismes biologiques impliqués dans ce groupe de problèmes majeurs de santé publique. Les voies de recherches actuelles sont résumées, les voies futures sont indiquées et des recommandations sont présentées. Les principaux partenaires institutionnels intervenant dans chaque cas sont cités. Lorsqu'elles existent, les controverses scientifiques et quelquefois politico-médiatiques sont explicitées. L'ouvrage traite les questions suivantes: 1-Les cancers hormonodépendants: Les mécanismes de base, les cancers du sein, les cancers de la prostate. 2-Le traitement substitutif de la ménopause. 3-L'obésité, les diabète de type 2. 4-Les hormones et le vieillissement. 5-Les perturbateurs hormonaux 6-Les hormones en Zootechnie.

• Sommario/riassunto: Optimization plays an invaluable role in the exciting and rapidly developing field of computer vision, yet this importance is often overlooked in the literature. This practical and authoritative text/reference presents a broad introduction to the optimization methods used specifically in computer vision. In order to facilitate understanding, the presentation of the methods is supplemented by simple flow charts, followed by pseudocode implementations that reveal deeper insights into their mode of operation. These discussions are further supported by examples taken from important applications in computer vision. Topics and features: Provides a comprehensive overview of computer vision-related optimization Covers a range of techniques from classical iterative multidimensional optimization to cutting-edge topics of graph cuts and GPU-suited total variation-based optimization Describes in detail the optimization methods employed in computer vision applications Illuminates key concepts with clearly written and step-by-step explanations Presents detailed information on implementation, including pseudocode for most methods This easy-to-follow and applications-focused book is an essential resource for researchers and practitioners seeking guidance on implementing specific methods in computer vision. Marco Alexander Treiber is a ; software developer at ASM Assembly Systems, Munich, Germany, where he is Technical Lead in Image Processing for the Vision System of SiPlace placement machines, used in SMT assembly. Among his other publications is the successful Springer title An Introduction to Object Recognition.
