Growing, Buckling, and Swirling: motility from polymerization
Naveen Kumar D, Michael J. Shelley, Brato Chakrabarti
Locomotion in low-Reynolds-number environments is achieved through a remarkable diversity of strategies, from flagellar rotation and ciliary beating to large-scale body deformation…
Condensation dynamics of sticky and anchored flexible biopolymers
Adam R. Lamson, Mohammadhossein Firouznia, Michael J. Shelley
Cells regulate gene expression in part by forming DNA-protein condensates in the nucleus. While existing theories describe the equilibrium size and stability of such condensates, t…
Collective multicellular patterns arising from cadherin-linked cytoskeletal domains
XinXin Du, Ido Lavi, Michael J. Shelley
In multicellular systems, adhesion complexes, such as those composed of E-cadherin and associated catenins, mechanically couple neighboring cells by directly linking their actin-ba…
The physical consequences of sperm gigantism
Jasmin Imran Alsous, Brato Chakrabarti, Bryce Palmer +1
The male fruit fly produces ~1.8 mm long sperm, thousands of which can be stored until mating in a ~200 micron sac, the seminal vesicle. While the evolutionary pressures driving su…
Correlations, mean-field limits, and transition to the concentrated regime in motile particle suspensions
Bryce Palmer, Scott Weady, Michael O'Brien +2
Suspensions of swimming particles exhibit complex collective behaviors driven by hydrodynamic interactions, showing persistent large-scale flows and long-range correlations. While…
