Aging is a multifactorial phenomenon that involves the different levels of biological organization, leading to the old age frailty and dysfunction, which eventually culminates in pathologies and death.

Seed priming is a pregerminative technique for improving seed germination and vigor, it involves imbibition of seeds in water under controlled conditions to initiate early events of germination followed by drying the seed back to its initial moisture content, in order to have a control on germination. Beaucarnea gracilis (Nolinaceae)...
In this work we developed the theory to characterize the structure of optimal sequential tests for experiments, introducing a random horizon, unlike an infinity horizon as in the classical theory. We analyzed the optimal sequential tests found with random horizon in terms of probability ratio and when a particular case...
