Analyse (mathématiques)L'analyse (du grec , délier, examiner en détail, résoudre) a pour point de départ la formulation rigoureuse du calcul infinitésimal. C'est la branche des mathématiques qui traite explicitement de la notion de limite, que ce soit la limite d'une suite ou la limite d'une fonction. Elle inclut également des notions comme la continuité, la dérivation et l'intégration. Ces notions sont étudiées dans le contexte des nombres réels ou des nombres complexes.
Prior artPrior art (also known as state of the art or background art) is a concept in patent law used to determine the patentability of an invention, in particular whether an invention meets the novelty and the inventive step or non-obviousness criteria for patentability. In most systems of patent law, prior art is generally defined as anything that is made available, or disclosed, to the public that might be relevant to a patent's claim before the effective filing date of a patent application for an invention.
T-tubuleT-tubules (transverse tubules) are extensions of the cell membrane that penetrate into the center of skeletal and cardiac muscle cells. With membranes that contain large concentrations of ion channels, transporters, and pumps, T-tubules permit rapid transmission of the action potential into the cell, and also play an important role in regulating cellular calcium concentration. Through these mechanisms, T-tubules allow heart muscle cells to contract more forcefully by synchronising calcium release from the sarcoplasmic reticulum throughout the cell.
