Persistence-Driven Void Formation in Dense Active-Passive Mixtures
Giulia Janzen, Liesbeth M. C. Janssen, Nuno A. M. Araújo +2
It is well established that dilute active dopants can melt an arrested amorphous solid by enhancing cage breaking and accelerating structural relaxation. Yet it remains unclear whe…
Emergent Dynamics of Active Systems on Curved Environments
Euan D. Mackay, Giulia Janzen, D. A. Matoz Fernandez +1
Curvature plays a central role in the proper function of many biological processes. With active matter being a standard framework for understanding many aspects of the physics of l…
Machine learning short-ranged many-body interactions in colloidal systems using descriptors based on Voronoi cells
Rinske M. Alkemade, Rastko Sknepnek, Frank Smallenburg +1
Machine learning (ML) strategies are opening the door to faster computer simulations, allowing us to simulate more realistic colloidal systems. Since the interactions in colloidal…
Correlated cell movements drive epithelial finger formation
Sander C. Kammeraat, Yann-Edwin Keta, Paul Appleton +5
Epithelia form protective barriers in multicellular organisms. To maintain homeostasis, they must be able to regenerate and heal damaged areas. This occurs through collective cell…
Active Filaments on Curved Surfaces: From Single Filaments to Dilute Suspensions
Giulia Janzen, Euan D. Mackay, Rastko Sknepnek +1
Curvature plays a central organizational role in active polymer dynamics. Using large-scale Langevin-dynamics simulations, we study active semiflexible filaments confined to smooth…
Cell-level modelling of homeostasis in confined epithelial monolayers
KVS Chaithanya, Jan Rozman, Andrej Košmrlj +1
Tissue homeostasis, the biological process of maintaining a steady state in tissue via control of cell proliferation, death, and metabolic function, is essential for the developmen…
