Markov chain Monte Carlo sampling propagators, including numerical integrators for stochastic dynamics, are central to the calculation of thermodynamic quantities and determination of structure for molecular systems. Efficiency is paramount, and to a grea... see more

This paper considers a stochastic susceptible exposed infectious recovered (SEIR) epidemic model with varying population size and vaccination. We aim to study the global dynamics of the reduced nonlinear stochastic proportional differential system. We fir... see more

We investigate the stochastic dynamics of a prey-predator type ecosystem with time delay and the discrete random environmental fluctuations. In this model, the delay effect is represented by a time delay parameter and the effect of the environmental rando... see more

As an important restrictive factor of ecological construction on the Loess Plateau, the study of soil moisture dynamics is essential, especially under the impact of climate change on hydrological processes. In this study, the applicability of the Laio soi... see more

As water demand is exponentially increasing and supplies are scarce, integrated urban water management is an important task in all cities and regions. It is a multi-objective problem, because of the many objectives and criteria that should be analyzed. Th... see more

This work considers dynamics of non-equilibrium long wave fluctuations in systems of particles interacting with multiplying and capturing media, generated by external stochastic field. General dynamic equations for long wave fluctuations are obtained usin... see more

This paper takes a system dynamic approach to study homogeneous texts where the dynamics of the lexical richness of such texts over time are of the focal concern. It is hypothesized that the progress of the lexical complexity is driven by how far away thi... see more

Drug resistance to single therapeutic treatment in HIV infected individuals has promoted research into combined treatments. In this paper we propose a stochastic model undercombined therapeutic treatment by extending the model of HIV pathogenesis under tr... see more

We provide an Effective Potential Formulation for non-coupled (i.e. independent) Stochastic Partial Differential Equations with additive noise using the Hojman et al. method for writing the associated Lagrangean function. We show that this Potential is ab... see more
