Recovering the spatiotemporally dependent diffusion and advection coefficients in a pathway-based Keller--Segel model
Yu'an Li, Lingyun Qiu, Min Tang +3
We investigate an inverse coefficient problem for an augmented Keller--Segel model arising in the description of phototactic and chemotactic population dynamics. The spatiotemporal…

Sediment Concentration Estimation via Multiscale Inverse Problem and Stochastic Homogenization
Jiwei Li, Lingyun Qiu, Zhongjing Wang +2
We develop a multiscale framework for estimating sediment concentration in water flow from acoustic wave measurements. At the microscopic scale, the sediment distribution is modele…
