The hypothesis presented in this paper is based on the similarity of the human evolution to that of simple discrete nonlinear fractional (with power-law memory) systems.

We propose a probabilistic completeness whose samples are the values of deterministic completeness. When the difference between 1 and the mean of probabilistic co

Differences in the shape of mortality curves reflect changes in the rates and causes of mortality and are related to both endogenous and exogenous factors. Shape variations of mortality curves over time as well as across regions may help to decipher

Empirical time series data for births and deaths exhibits strong evidence of seasonality patterns at both national and subnational levels. In this paper, we evaluate the forecasting performance of a
