Lumens as active balloons: a biological physics review
Sebastian Echeverría-Alar, Badri Narayanan Narasimhan, Stephanie I Fraley +1
Lumens are cavities enclosed by polarized cells that are essential for organ function, from nutrient transport in the gut to gas exchange in the lungs. Defects in lumen formation a…

Boundary-driven delayed-feedback control of spatiotemporal dynamics in excitable media
Sebastian Echeverria-Alar, Wouter-Jan Rappel
Scroll-wave instabilities in excitable domains are central to life-threatening arrhythmias, yet practical methods to stabilize these dynamics remain limited. Here, we investigate t…

Annihilation dynamics during spiral defect chaos revealed by particle models
Timothy J Tyree, Patrick Murphy, Wouter-Jan Rappel
Pair-annihilation events are ubiquitous in a variety of spatially extended systems and are often studied using computationally expensive simulations. Here we develop an approach in…
