Subhaya's work is accepted in Biophysical Journal, congrats!  This work describes competing roles of persistent cell motility and long-range elastic interactions at a stiffness interface with a combination of simulations, elasticity theory and scaling analyses. We are very happy to see that reviewer 3 liked the paper enough to describe it as "Overall, this is very interesting and solid modeling work"!  We also thank our collaborators in this paper: Arvind Gopinath from UC Merced, and Xinpeng Xu and his student, Haiqin, from Guangdong Technion.
