Morphological instability and roughening of growing 3D bacterial colonies

A Martínez-Calvo, T Bhattacharjee… - Proceedings of the …, 2022 - National Acad Sciences
How do growing bacterial colonies get their shapes? While colony morphogenesis is well
studied in two dimensions, many bacteria grow as large colonies in three-dimensional (3D) …

Shape effects in the fluctuations of random isochrones on a square lattice

I Álvarez Domenech, J Rodríguez-Laguna, R Cuerno… - Physical Review E, 2024 - APS
We consider the isochrone curves in first-passage percolation on a 2D square lattice, ie, the
boundary of the set of points which can be reached in less than a given time from a certain …

Dynamics of bacterial deposition in evaporating drops

A Agrawal, S Sinha, R Mukherjee, D Mampallil - Physics of Fluids, 2020 - pubs.aip.org
Evaporation of drops almost always deposits their suspended particles at the drop edge.
The dynamics of this process and the resulting patterns depend upon various parameters …

Instability and fingering of interfaces in growing tissue
