Gompertz mortality law and scaling behaviour of the Penna model
J. B. Coe, Y. Mao
The Penna model is a model of evolutionary ageing through mutation accumulation where traditionally time and the age of an organism are treated as discrete variables and an organis…
Population Dynamics in the Penna Model
J. B. Coe, Y. Mao
We build upon the recent steady-state Penna model solution, Phys.Rev.Lett. 89, 288103 (2002), to study the population dynamics within the Penna model. We show, that any perturbatio…
Analytical solution of a generalized Penna model
J. B. Coe, Y. Mao
In 1995 T.J.Penna introduced a simple model of biological aging. A modified Penna model has been demonstrated to exhibit behaviour of real-life systems including catastrophic senes…
Solvable senescence model with positive mutations
J. B. Coe, Y. Mao, M. E. Cates
We build upon our previous analytical results for the Penna model of senescence to include positive mutations. We investigate whether a small but non-zero positive mutation rate gi…
A solvable senescence model showing a mortality plateau
J. B. Coe, Y. Mao, M. E. Cates
We present some analytic results for the steady states of the Penna model of sen escence, generalised to allow genetically identical individuals to die at differ ent ages via an ar…
