Between certain electron states the electric dipole transition rate may be zero due to one or more selection rules, particularly the angular momentum selection rule.
22.
Models the transition rate from the compartment of susceptible individuals to the compartment of infectious individuals, so that it is called the force of infection.
23.
Models of DNA evolution were first proposed in 1969 by Jukes and Cantor, assuming equal transition rates as well as equal equilibrium frequencies for all bases.
24.
The transition rate decreases by a factor of about 1000 from one multipole to the next one, so the lowest multipole transitions are most likely to occur.
25.
Additionally the transition rate from hermaphroditism to dioecy was approximately twice the reverse rate suggesting greater diversification among hermphrodites and demonstrating the recurrent evolution of dioecy in mosses.
26.
More generally the transition rates are given in form of a finite measure c _ \ Lambda ( \ eta, d \ xi ) on S ^ \ Lambda.
27.
A feedback fluid queue is a model where the model parameters ( transition rate matrix and drift vector ) are allowed to some extent to depend on the buffer content.
28.
Completion and transition rates to tertiary education are highly correlated with family incomes; there are 3 times more students at the university level from families in upper two income quintiles.
29.
Further investigation, and theoretical work using elementary quantum mechanics and transition rate / transition probability calculations, showed that the effect was a radiationless effect more than an internal conversion effect.
30.
Kolmogorov's criterion states that the necessary and sufficient condition for a process to be reversible is that the product of transition rates around a closed loop must be the same in both directions.
