  2. Coalescent theory - Wikipedia

    en.wikipedia.org/wiki/Coalescent_theory

    Coalescent theory is a model of how alleles sampled from a population may have originated from a common ancestor. In the simplest case, coalescent theory assumes no recombination , no natural selection , and no gene flow or population structure , meaning that each variant is equally likely to have been passed from one generation to the next.

  3. Coalescence (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Coalescence_(chemistry)

    In chemistry, coalescence is a process in which two phase domains of the same composition come together and form a larger phase domain. In other words, the process by which two or more separate masses of miscible substances seem to "pull" each other together should they make the slightest contact.

    Coalescence (chemistry), the process by which two or more separate masses of miscible substances seem to "pull" each other together should they make the slightest contact; Coalescence (physics), the merging of two or more droplets, bubbles or particles into one; Coalescer, device which induces coalescence in a medium

  5. Clar's rule - Wikipedia

    en.wikipedia.org/wiki/Clar's_rule

    Clar's rule has also been supported by experimental results about the distribution of π-electrons in polycyclic aromatic hydrocarbons, [7] valence bond calculations, [8] and nucleus-independent chemical shift studies. [9] Clar's rule is widely applied in the fields of chemistry and materials science.

  6. Thermodynamic activity - Wikipedia

    en.wikipedia.org/wiki/Thermodynamic_activity

    The relative activity of a species i, denoted a i, is defined [4] [5] as: = where μ i is the (molar) chemical potential of the species i under the conditions of interest, μ o i is the (molar) chemical potential of that species under some defined set of standard conditions, R is the gas constant, T is the thermodynamic temperature and e is the exponential constant.

  7. Multispecies coalescent process - Wikipedia

    en.wikipedia.org/wiki/Multispecies_coalescent...

    Multispecies Coalescent Process is a stochastic process model that describes the genealogical relationships for a sample of DNA sequences taken from several species. [ 1 ] [ 2 ] It represents the application of coalescent theory to the case of multiple species.

  8. Eyring equation - Wikipedia

    en.wikipedia.org/wiki/Eyring_equation

    The Eyring equation (occasionally also known as Eyring–Polanyi equation) is an equation used in chemical kinetics to describe changes in the rate of a chemical reaction against temperature. It was developed almost simultaneously in 1935 by Henry Eyring , Meredith Gwynne Evans and Michael Polanyi .

  9. Coulson–Fischer theory - Wikipedia

    en.wikipedia.org/wiki/Coulson–Fischer_theory

    In theoretical chemistry and molecular physics, Coulson–Fischer theory provides a quantum mechanical description of the electronic structure of molecules. The 1949 seminal work of Coulson and Fischer [1] established a theory of molecular electronic structure which combines the strengths of the two rival theories which emerged soon after the advent of quantum chemistry - valence bond theory ...
