A hybrid computer simulation is used to study the effect of heterogeneous matrix density (pb) on the segregation and orientation of short-chain molecules, i.e., dimer, trimer, etc., a model for polymer dispersed liquid crystal (PDLC) in an external field. Size of molecular aggregates is found to...

Viral load is examined, as a function of primary viral growth factor (Pg) and mutation, through a computer simulation model for HIV immune response. Cell-mediated immune response is considered on a cubic lattice with four cell types: macrophage (M), helper (H), cytotoxic (C), and virus (V)....

A computer simulation model is used to study the density profile and flow of a miscible gaseous fluid mixture consisting of differing constituent masses (mA=mB/3) through an open matrix. The density profile is found to decay with the height ∝exp(−mA(B)h), consistent with the barometric...

Mobility of cell types in our HIV immune response model is subject to an intrinsic mobility and an explicit directed mobility, which is governed by Pmob. We investigate how restricting the explicit mobility, while maintaining the innate mobility of a viral-infected cell, affects the model's...

A fuzzy set of 10 interactions for macrophages, helper cells, cytotoxic cells, and virion is introduced to study their population dynamics in an immune response relevant to HIV. Viral mutation is considered and cellular automata are used for local interactions. In absence of mutation, after an...

A computer simulation model is used to study the flow of gas from a source through open porous media on a simple cubic lattice with a pressure bias. This model is used to represent marine sediments through which fluid flows. Isotropic and layered porous media are considered and the gas fluid is...

A Monte Carlo computer simulation model is presented to study the evolution of stock price and the distribution of price fluctuation. The resistance is described by an elastic energy Ee=e·x2 resulting from the price deviation x from an initial value and the momentum trading by the potential...
