报告题目:A THEORY ENCOMPASSING EXPERIMENTAL DESIGN AND DATA FITTING FOR HORMESIS AND ECOLOGICAL PARADOXES

时 间:11月8日下午3:00

地 点:齐云楼911

报告摘要:Hormesis, involving biphasic responses to increasing amounts of a stimulation, challenges decision-making in management of cancer, neurodegenerative diseases, nutrition and ecotoxicology. A model, based on the Ricker equation with three critical parameters, revealed hormetic biphasic dose and timing responses, either in a J-shape or an inverted U-shape, yielding a homeostatic change or a catastrophic shift and hormetic effects in many parameter regions. Such effects were enhanced by multiple low-level stimulations, thereby reducing threshold levels, maximum responses and inhibition, thus providing insights into hormetic effects and showing how to reduce risks involved in dosage decisions for medical treatments. For ecological applications, data fitting demonstrates the effectiveness of our framework to use experimental data to inform intervention strategies for species with discrete generations under multiple impulsive interventions.
