Aging and lévy distributions in sandpiles [PDF]

open access: yes, 1999
Aging in complex systems is studied via the sandpile model. Relaxation of avalanches in sandpiles is observed to depend on the time elapsed since the begining of the relaxation. Levy behavior is observed in the distribution of characteristic times. In this way, aging and self-organized criticality appear to be closely related.

Analysis of the standing age distribution and age-specific recruitment rate of the George River and Beverly barren-ground caribou populations

open access: yesRangifer, 1991
The primary advantage of the standing age distribution of a population is that it can be sampled. Analysis of the age frequencies for estimates of survival rates and determinations of population status by life table construction depend heavily on ...

Age-distribution dynamics and aging indexes [PDF]

open access: yesDemography, 1997
Abstract I analyze the dynamics of the age distribution as some vital rates change. When the fertility or mortality rate declines, the age distribution often manifests a dynamic stochastic-dominance relationship. I also propose some alternative indexes for measuring population aging.
