A butterfly catastrophe model of motivation in organization: Academic performance.

SJ Guastello - Journal of Applied Psychology, 1987 - psycnet.apa.org
This monograph advances and tests a model proposing that changes in performance levels,
rates of absenteeism, and turnover are best described by a nonlinear interactive process …

Periodic solutions and chaos in a non-linear model for the delayed cellular immune response

AA Canabarro, IM Gléria, ML Lyra - Physica A: Statistical Mechanics and its …, 2004 - Elsevier
We model the cellular immune response using a set of non-linear delayed differential
equations. We observe that the stationary solution becomes unstable above a critical …

Mathematical models of humoral immune response

SJ Merrill - Modeling and differential equations in biology, 2017 - taylorfrancis.com
This chapter provides a survey of several mathematical models of the humoral immune
response. They are predominantly models of the population levels and interaction of various …

A threshold model simulating humoral immune response to replicating antigens

HI Freedman, JA Gatica - Mathematical Biosciences, 1977 - Elsevier
A threshold model is proposed for humoral immune response to replicating antigen. The
model incorporates two trigger functions, the first of which causes lymphocyte growth, and …
