Efficient Generation of Membrane and Solvent Tetrahedral Meshes for Ion Channel Finite Element Calculation
Zhen Chao, Sheng Gui, Benzhuo Lu +1
A finite element solution of an ion channel dielectric continuum model such as Poisson-Boltzmann equation (PBE) and a system of Poisson-Nernst-Planck equations (PNP) requires tetra…

Sparse Representation of Gaussian Molecular Surface
Sheng Gui, Minxin Chen, Benzhuo Lu
In this paper, we propose a model and algorithm for sparse representing Gaussian molecular surface. The original Gaussian molecular surface is approximated by a relatively small nu…
