  2. Mathematical model - Wikipedia

    en.wikipedia.org/wiki/Mathematical_model

    An inductive model arises from empirical findings and generalization from them. The floating model rests on neither theory nor observation, but is merely the invocation of expected structure. Application of mathematics in social sciences outside of economics has been criticized for unfounded models. [5]

  3. Living systems - Wikipedia

    en.wikipedia.org/wiki/Living_systems

    Below the level of living systems, he defines space and time, matter and energy, information and entropy, levels of organization, and physical and conceptual factors, and above living systems ecological, planetary and solar systems, galaxies, etc. [3] [4] [5] Miller's central thesis is that the multiple levels of living systems (cells, organs ...

  4. Mathematical and theoretical biology - Wikipedia

    en.wikipedia.org/wiki/Mathematical_and...

    The solution of the equations, by either analytical or numerical means, describes how the biological system behaves either over time or at equilibrium. There are many different types of equations and the type of behavior that can occur is dependent on both the model and the equations used. The model often makes assumptions about the system.

  5. Life - Wikipedia

    en.wikipedia.org/wiki/Life

    Life is a quality that distinguishes matter that has biological processes, such as signaling and self-sustaining processes, from matter that does not. It is defined descriptively by the capacity for homeostasis , organisation , metabolism , growth , adaptation , response to stimuli , and reproduction .

  6. Markov chain - Wikipedia

    en.wikipedia.org/wiki/Markov_chain

    Markov processes can also be used to generate superficially real-looking text given a sample document. Markov processes are used in a variety of recreational "parody generator" software (see dissociated press, Jeff Harrison, [110] Mark V. Shaney, [111] [112] and Academias Neutronium). Several open-source text generation libraries using Markov ...

  7. Stochastic process - Wikipedia

    en.wikipedia.org/wiki/Stochastic_process

    The term stochastic process first appeared in English in a 1934 paper by Joseph Doob. [60] For the term and a specific mathematical definition, Doob cited another 1934 paper, where the term stochastischer Prozeß was used in German by Aleksandr Khinchin, [63] [64] though the German term had been used earlier, for example, by Andrei Kolmogorov ...

  8. Birth–death process - Wikipedia

    en.wikipedia.org/wiki/Birth–death_process

    In queueing theory the birth–death process is the most fundamental example of a queueing model, the M/M/C/K/ /FIFO (in complete Kendall's notation) queue. This is a queue with Poisson arrivals , drawn from an infinite population, and C servers with exponentially distributed service times with K places in the queue.

  9. Bioenergetics - Wikipedia

    en.wikipedia.org/wiki/Bioenergetics

    Bioenergetics is a field in biochemistry and cell biology that concerns energy flow through living systems. [1] This is an active area of biological research that includes the study of the transformation of energy in living organisms and the study of thousands of different cellular processes such as cellular respiration and the many other metabolic and enzymatic processes that lead to ...
