Stochastic host-parasite interaction models

Journal of Mathematical Biology, 2000
We contribute to the discussion of causes and effects of aggregation (overdispersion) of macroparasite counts, focussing particularly upon the effects of clumped infections and parasite-induced host mortality. The simple nonlinear stochastic model for the evolution of the parasite load of a single host, investigated in Isham (1995), is extended to ...

Reasoning about Interactive Systems with Stochastic Models

2001
Several techniques for specification exist to capture certain aspects of user behaviour, with the goal of reasoning about the usability of the system and other human-factors related issues. One such approach is to encode a set of assumptions about user behaviour in a user model.

Stochastic resonance in interacting systems

Physica A: Statistical Mechanics and its Applications, 1998
Abstract We analyze the phenomenon of stochastic resonance in a system of interacting particles, each one subject to a double-well potential and an external oscillating field. In this system there exists a symmetry breaking giving rise to a dynamic phase transition between one state in which the particles oscillate between the wells and another in ...

Stochastic population models with interacting species.

Journal of mathematical biology, 2001
A stochastic model concerning the evolution of a multi-species population is presented assuming species competition for a habitat. The model takes into account colonization, death and replacement for all individuals. Two cases are treated: (i) colonizations follow the hierarchic rule by which species of lower rank are always outcompeted by those of ...

Stochastic theory of ecological interactions

Ecological Modelling, 1982
Abstract It is possible, using the distribution of random numbers of random variables, to derive bimodal vertical distributions of phytoplankton biomass similar to those observed in nature. On the basis of the distribution of pseudorandom events, equations for the probability of individual mortality from one of several reasons, and for the capture of

Stochastic Specificity in Neural Interaction

1993
We present in this communication results from a dynamical model of two interacting stochastic neurons, simple enough to provide the understanding of basic mechanisms by which the stochastic nature of units enhances information processing capabilities. The active role played by noise or randomness in stochastic integrating and firing units is analyzed ...
