Tumor boundary instability induced by pressure feedback
Yu Feng, Yeyu Zhang, Kewei Zhou
We consider a Hele--Shaw-type tumor growth model obtained from the incompressible limit of a porous-medium equation. The limiting model preserves the patch structure of the tumor d…

LARC: Lazy Adaptive Reachability Certification of Robot Manipulator Trajectories
Yu Feng, Hao Wu, Yuzhe Wang +1
Discrete trajectory checks can miss collisions between sampled robot states. Reachability-based certification bounds motion between states, but uniform time partitions waste comput…
