A stochastic model for internal HIV dynamics

A stochastic model for early HIV-1 population dynamics.

A simple stochastic mathematical model is developed and investigated for early human immunodeficiency virus type-1 (HIV-1) population dynamics. The model, which is a multi-dimensional diffusion process, includes activated uninfected CD4(+)T cells, latently and actively infected CD4(+)T cells and free virions occurring in plasma. Stochastic effects are assumed to arise in the process of infectio...

Term Structure Dynamics in a Model with Stochastic Internal Habit

The expectations hypothesis is violated in the U.S. nominal term structure of interest rates. This so-called ”expectations puzzle” can be captured by some descriptive models of the term structure with time-varying risk premium. This paper provides an economic explanation for the success of these reduced-form specifications of pricing kernels. Specifically, we show that a consumption-based asset...

Proposing A stochastic model for spread of corona virus dynamics in Nigeria

The emergence of corona virus (COVID-19) has create a great public concern as the outbreak is still ongoing and government are taking actions such as holiday extension, travel restriction, temporary closure of public work place, borders, schools, quarantine/isolation, social distancing and so on. To mitigate the spread, we proposed and analyzed a stochastic model for the continue spread of coro...

A Stochastic Optimization Model for Groundwater Management

A Stochastic Model for Water Resources Management

Irrigation water management is crucial for agricultural production and livelihood security in many regions and countries throughout the world. Over the past decades, controversial and conflictladen water-allocation issues among competing municipal, industrial and agricultural interests have raised increasing concerns. Particularly, growing population, varying natural conditions and shrinking wa...
