Step - by - Step Evolution with State - Dependent Mutations ∗
This paper considers the application of Ellison’s (2000) “RadiusModified Coradius” Theorem to models of evolution with state-dependent mutations. A reformulated theorem is presented, with a crucial role played by the most probable evolutionary paths between states. The form of such paths is liable to change outside of the uniform mutations case, with concomitant effects on both long-run selecti...
متن کاملA stochastic gene evolution model with time dependent mutations.
We develop here a new class of gene evolution models in which the nucleotide mutations are time dependent. These models allow to study nonlinear gene evolution by accelerating or decelerating the mutation rates at different evolutionary times. They generalize the previous ones which are based on constant mutation rates. The stochastic model developed in this class determines at some time t the ...
متن کاملState Dependent Multi channel Queuing System with Ordered Entry
In the present study, we analyze the multi-channel service system with ordered entryfrom finite-source and finite-storage at each channel. The arrival and service rates are assumedto be state dependent. The steady state probabilities of the system are obtained by usingChapmann-Kolmogorov equations. Some other performance indices viz. utilization of servers,expected number of units in the system...
متن کاملNonlinear second order evolution equations with state-dependent delays
We consider second order quasilinear parabolic equations where also the main part contains functional dependence and state-dependent delay on the unknown function. Existence and some qualitative properties of the solutions are shown.
متن کاملPolarization-state evolution in recirculating loops with polarization-dependent loss.
We analyze the evolution of the polarization state of a signal in a recirculating loop with polarization-dependent loss. We show that the polarization-state evolution in experiments is in qualitative agreement with our analysis, and we discuss the relationship between the polarization-state evolution and the Q factor.
