  • Jactitation

    Jactitation or jactitation of marriage is an archaic cause of action in English and in Irish law. Where one person falsely asserts that he or she is married to another, the wronged party could obtain an order restraining further repetitions of the falsehood. The action was abolished in England in 1986 and in Ireland in 1995.

  • Jactitation (medicine)

    In medicine, jactitation (sometimes jactation) is a restless tossing in bed, seen in severe fevers and certain mental disorders; or more generally a tossing to and fro or jerking and twitching of the body. It derives ultimately from the Latin jactitare, to toss about.

  • Activation function

    Activation function

    In artificial neural networks, the activation function of a node defines the output of that node given an input or set of inputs. A standard computer chip circuit can be seen as a digital network of activation functions that can be "ON" (1) or "OFF" (0), depending on input. This is similar to the behavior of the linear perceptron in neural networks. However, only nonlinear activation functions allow such networks to compute nontrivial problems using only a small number of nodes. In artificial neural networks, this function is also called the transfer function.

  • Neutron activation

    Neutron activation is the process in which neutron radiation induces radioactivity in materials, and occurs when atomic nuclei capture free neutrons, becoming heavier and entering excited states. The excited nucleus often decays immediately by emitting gamma rays, or particles such as beta particles, alpha particles, fission products, and neutrons (in nuclear fission ). Thus, the process of neutron capture, even after any intermediate decay, often results in the formation of an unstable activation product. Such radioactive nuclei can exhibit half-lives ranging from small fractions of a second to many years.

  • Activation

    Activation in (bio-)chemical sciences generally refers to the process whereby something is prepared or excited for a subsequent reaction.

  • Behavioral activation

    Behavioral activation (BA) is a third generation behavior therapy for treating depression. It is one of many functional analytic psychotherapies which are based on a Skinnerian psychological model of behavior change, generally referred to as applied behavior analysis. This area is also a part of what is called clinical behavior analysis (CBA) (see behavior therapy ) and makes up one of the most effective practices in the professional practice of behavior analysis.
