Nonlocal modeling of opinion alignment and environmental feedback: Spatial aggregation and non-consensus patterns
Rui Wang, Yunfeng Xiong, Zhengru Zhang +1
The formation of public opinion in modern information environments is shaped by the interplay between social conformity and information exposure. While social interactions promote…
Efficient structure-preserving scheme for chemotaxis PDE system with singular sensitivity in crime and epidemic modeling
Rui Wang, Yunfeng Xiong, Zhengru Zhang
The chemotaxis PDE system with singular sensitivity was originally proposed by Short et al. (Math. Mod. Meth. Appl. Sci., 2008) as the continuum limit of a biased random walk model…
An efficient stochastic particle method for high-dimensional nonlinear PDEs
Zhengyang Lei, Sihong Shao, Yunfeng Xiong
Numerical resolution of high-dimensional nonlinear PDEs remains a huge challenge due to the curse of dimensionality. Starting from the weak formulation of the Lawson-Euler scheme,…
Compressing the memory variables in constant-Q viscoelastic wave propagation via an improved sum-of-exponentials approximation
Xu Guo, Shidong Jiang, Yunfeng Xiong +1
Earth introduces strong attenuation and dispersion to propagating waves. The time-fractional wave equation with very small fractional exponent, based on Kjartansson's constant-Q th…
Distributed local spline simulator for wave propagation
Xu Guo, Yaomeng Li, Yunfeng Xiong
Numerical simulation of wave propagation in elastic media faces the challenges arising from increasing demand of high resolution in modern 3-D imaging applications, which requires…
Performance evaluations on the parallel CHAracteristic-Spectral-Mixed (CHASM) scheme
Yunfeng Xiong, Yong Zhang, Sihong Shao
Performance evaluations on the deterministic algorithms for 6-D problems are rarely found in literatures except some recent advances in the Vlasov and Boltzmann community [Dimarco…
A short-memory operator splitting scheme for constant-Q viscoelastic wave equation
Yunfeng Xiong, Xu Guo
We propose a short-memory operator splitting scheme for solving the constant-Q wave equation, where the fractional stress-strain relation contains multiple Caputo fractional deriva…
SPADE: Sequential-clustering Particle Annihilation via Discrepancy Estimation
Sihong Shao, Yunfeng Xiong
For an empirical signed measure , particle annihilation (PA) removes particles from both $\{x_i\}_{i=…
