Investigating the integrate and fire model as the limit of a random discharge model: a stochastic analysis perspective

Jian-Guo Liu, Ziheng Wang, Yantong Xie +2

In the mean field integrate-and-fire model, the dynamics of a typical neuron within a large network is modeled as a diffusion-jump stochastic process whose jump takes place once th…

A unified structure preserving scheme for a multi-species model with a gradient flow structure and nonlocal interactions via singular kernels

Yong Zhang, Yu Zhao, Zhennan Zhou

In this paper, we consider a nonlinear and nonlocal parabolic model for multi-species ionic fluids and introduce a semi-implicit finite volume scheme, which is second order accurat…

Multi-level Monte Carlo path integral molecular dynamics for thermal average calculation in the nonadiabatic regime

Xiaoyu Lei, Zhennan Zhou

With the path integral approach, the thermal average in a multi-electronic-state quantum systems can be approximated by the ring polymer representation on an extended configuration…

Field model for complex ionic fluids: analytical properties and numerical investigation

Jian-Guo Liu, Jinhuan Wang, Yu Zhao +1

In this paper, we consider the field model for complex ionic fluids with an energy variational structure, and analyze the well-posedness to this model with regularized kernels. Fur…

A structure preserving numerical scheme for Fokker-Planck equations of neuron networks: numerical analysis and exploration

Jingwei Hu, Jian-Guo Liu, Yantong Xie +1

In this work, we are concerned with the Fokker-Planck equations associated with the Nonlinear Noisy Leaky Integrate-and-Fire model for neuron networks. Due to the jump mechanism at…

Towards understanding the boundary propagation speeds in tumor growth models

Jian-Guo Liu, Min Tang, Li Wang +1

At the continuous level, we consider two types of tumor growth models: the cell density model, which is based on the fluid mechanical construction, is more favorable for scientific…
