  living system
  Definition : Living systems are open self-organizing life forms that interact with their environment. These systems are maintained by flows of information, energy and matter.
  Some scientists have proposed in the last few decades that a general living systems theory is required to explain the nature of life.
  Such a general theory, arising out of the ecological and biological sciences, attempts to map general principles for how all living systems work.
  Instead of examining (...)

• organ functions
  4 February 2018

  Organ functions
  Definition : Function of an organ in organ systems.
  Organ systems
  The notion of system (or apparatus) relies upon the concept of vital or organic function / organ functions : organ systems are a set of organs with a definite function.
  The enumeration of the principal functions - and consequently of the systems - remained almost the same since Antiquity, but the classification of them has been very various, e.g., compare Aristotle, Bichat, Cuvier.
  The notion of (...)

• signaling theory
  27 January 2018

  |WKP|
  Definition: Within evolutionary biology, signalling theory is a body of theoretical work examining communication between individuals, both within species and across species. The central question is when organisms with conflicting interests, such as in sexual selection, should be expected to provide honest signals (no presumption being made of conscious intention) rather than cheating. Mathematical models describe how signalling can contribute to an evolutionarily stable strategy. (...)

• noise
  27 January 2018

  Signals
  The formal study of the information content of signals is the field of information theory.
  The information in a signal is usually accompanied by noise.
  The term noise usually means an undesirable random disturbance, but is often extended to include unwanted signals conflicting with the desired signal (such as crosstalk). The prevention of noise is covered in part under the heading of signal integrity. The separation of desired signals from a background is the field of signal (...)

• signal

  WKP
  Definition : A signal as referred to in communication systems , signal processing , and electrical engineering is a function that "conveys information about the behavior or attributes of some phenomenon ".
  In the physical world, any quantity exhibiting variation in time or variation in space (such as an image) is potentially a signal that might provide information on the status of a physical system, or convey a message between observers, among other possibilities. It can be defined (...)

• parameters

  parameter WKP
  Definition: A parameter (from the Ancient Greek παρά, para: "beside", "subsidiary"; and μέτρον, metron: "measure"), generally, is any characteristic that can help in defining or classifying a particular system (meaning an event, project, object, situation, etc.). That is, a parameter is an element of a system that is useful, or critical, when identifying the system, or when evaluating its performance, status, condition, etc.
  In computing, a parameter is defined as "a reference or (...)
