Performance-enhancing substancePerformance-enhancing substances, also known as performance-enhancing drugs (PEDs), are substances that are used to improve any form of activity performance in humans. A well-known example of cheating in sports involves doping in sport, where banned physical performance-enhancing drugs are used by athletes and bodybuilders. Athletic performance-enhancing substances are sometimes referred as ergogenic aids. Cognitive performance-enhancing drugs, commonly called nootropics, are sometimes used by students to improve academic performance.
Microscope à force atomiquethumb|350px|Le premier microscope à force atomique du monde, au musée de la Science de Londres. Le microscope à force atomique (AFM pour atomic force microscope) est un type de microscope à sonde locale permettant de visualiser la topographie de la surface d'un échantillon. Inventé en 1985, par Gerd Binnig, Calvin Quate et Christoph Gerber, ce type de microscopie repose essentiellement sur l'analyse d'un objet point par point au moyen d'un balayage via une sonde locale, assimilable à une pointe effilée.
Agent-based modelAn agent-based model (ABM) is a computational model for simulating the actions and interactions of autonomous agents (both individual or collective entities such as organizations or groups) in order to understand the behavior of a system and what governs its outcomes. It combines elements of game theory, complex systems, emergence, computational sociology, multi-agent systems, and evolutionary programming. Monte Carlo methods are used to understand the stochasticity of these models.
Solid modelingSolid modeling (or solid modelling) is a consistent set of principles for mathematical and computer modeling of three-dimensional shapes (solids). Solid modeling is distinguished within the broader related areas of geometric modeling and computer graphics, such as 3D modeling, by its emphasis on physical fidelity. Together, the principles of geometric and solid modeling form the foundation of 3D-computer-aided design and in general support the creation, exchange, visualization, animation, interrogation, and annotation of digital models of physical objects.
Publicité en ligneLa publicité en ligne (ou e-publicité) désigne toute action visant à promouvoir un produit, service (économie), une marque ou une organisation auprès d'un groupe d'internautes et/ou de mobinautes contre une rémunération. La publicité en ligne est souvent rémunérée selon le nombre de clics faits par les internautes sur la publicité.
Modélisation tridimensionnelleLa modélisation tridimensionnelle est l'étape en infographie tridimensionnelle qui consiste à créer, dans un logiciel de modélisation 3D, un objet en trois dimensions, par ajout, soustraction et modifications de ses constituants. La révolution consiste à faire tourner un profil 2D autour d'un axe 3D : on obtient ainsi un volume de révolution. C'est la technique majoritairement utilisée dans le jeu vidéo, et le cinéma d'animation. La modélisation polygonale induit une marge d'erreur de proportions et de dimensions le plus souvent invisible à l'œil nu.
Prescriptive analyticsPrescriptive analytics is a form of business analytics which suggests decision options for how to take advantage of a future opportunity or mitigate a future risk, and shows the implication of each decision option. It enables an enterprise to consider "the best course of action to take" in the light of information derived from descriptive and predictive analytics. Prescriptive analytics is the third and final phase of business analytics, which also includes descriptive and predictive analytics.
Marine microorganismsMarine microorganisms are defined by their habitat as microorganisms living in a marine environment, that is, in the saltwater of a sea or ocean or the brackish water of a coastal estuary. A microorganism (or microbe) is any microscopic living organism or virus, that is too small to see with the unaided human eye without magnification. Microorganisms are very diverse. They can be single-celled or multicellular and include bacteria, archaea, viruses and most protozoa, as well as some fungi, algae, and animals, such as rotifers and copepods.

On retrouve aussi sur (voire dans) la plante des microbes plus ou moins ubiquistes et opportunistes, éventuellement pathogènes provenant de l'air et du sol.
