Existence and Uniqueness of the Positive Solution to a Predator-prey Model with Stochastic Perturbation
Itos formula Brownian motion existence and uniqueness
2012/9/24
In this paper, a predator-prey model is estab lished with the modified Holling-type II schemes with stochastic perturbation. We mainly use Lyapun ov function and comparison theorem to show that there ...
Stochastic approach and fluctuation theorem for ion transport
Stochastic approach fluctuation theorem ion transport
2011/1/5
We present a stochastic approach for ion transport at the mesoscopic level. The description takes into account the self-consistent electric field generated by the fixed and mobile charges as well as t...
This work faces the problem of the origin of the logarithmic character of the Gompertzian growth. We show that the macroscopic, deterministic Gompertz equation describes the evolution from the initial...
Deterministic and stochastic aspects of VEGF-A production and the cooperative behavior of tumoral cell colony
Deterministic stochastic aspects VEGF-A production
2011/1/5
A model is proposed to study the process of hypoxia-induced angiogenesis in cancer cells. The model accounts for the role played by the vascular endothelial growth factor (VEGF)-A in regulating the ox...
Rare events and stochastic tunneling in a two-locus system with recombination
Rare events stochastic tunneling two-locus system
2011/1/5
We study the evolution of a population in a two-locus genotype space, in which the negative effects of two single mutations are overcompensated in a high fitness double mutant. We discuss how the inte...
Stochastic Continuous Time Neurite Branching Models with Tree and Segment Dependent Rates
Stochastic Continuous Time Neurite Branching Models Tree Segment Dependent Rates
2010/11/15
In this paper we introduce a continuous time stochastic neurite branching model closely related to the discrete time stochastic BES-model. The discrete time BES-model is underlying current attempts t...
