We present a fast explicit operator splitting method to solve numerically the molecular beam epitaxy model in the 1-D case.The equation is split into nonlinear and linear parts which are approximated
Mathematics is being successfully applied to a number of important topics in biology and medicine like biofluids,data analysis,drug design and discovery,epidemiology,evolution,genetics,image processin
There has been a growing interest in the study of issues related to risk management and financial regulation in the financial mathematics community.
This paper attempts to provide a decision-theoretic foundation for the measurement of economic tail risk,which is related to utility theory and statistical model uncertainty.
We present a risk measure designed for the global and intrinsic risk of multidimensional interconnected system(banks or CCP).It first provides the total amount of liquidity that has to be reserved for
In this work,we present the accurate error estimates for three stateof-art algorithms of long-range electrostatic interaction in inhomogeneous and correlated molecular systems.They are the Ewald summa
We propose a surface potential trap model that attributes an energy cost to the interfacial charge dissociation.By defining a chemical potential μ,a reformulated CCPB can be reduced to the form of the
An overview will be given for our recent work on continuum modeling of macromolecular system: Poisson-Boltzmann electrostatic simulation,and its current developments toward model improvements at highe
To better understand the mechanism of hydraulic fracturing,we establish a new numerical model considering hydro-mechanical coupling.The model simulates mechanical behavior of rock formations using the
Landslides,avalanches,and debris flows are dangerous natural hazards to human beings.Environment pollutions like subsurface wastewater flow problems degenerate our life and cause disease.
