Spatiotemporal model of cellular mechanotransduction via Rho and YAP
Javor K. Novev, Mathias L. Heltberg, Mogens H. Jensen +1
How cells sense and respond to mechanical stimuli remains an open question. Recent advances have identified the translocation of Yes-associated protein (YAP) between nucleus and cy…
Memory effects, arches and polar defect ordering at the cross-over from wet to dry active nematics
Mehrana Raeisian Nejad, Amin Doostmohammadi, Julia Mary Yeomans
We use analytic arguments and numerical solutions of the continuum, active nematohydrodynamic equations to study how friction alters the behaviour of active nematics. Concentrating…
Bacteria solve the problem of crowding by moving slowly
Oliver J. Meacock, Amin Doostmohammadi, Kevin R. Foster +2
In systems as diverse as migrating mammals to road traffic, crowding acts to inhibit efficient collective movement. Bacteria, however, are observed to move in very dense groups con…
Flow states and transitions of an active nematic in a three dimensional channel
Santhan Chandragiri, Amin Doostmohammadi, Julia M. Yeomans +1
We use active nematohydrodynamics to study the flow of an active fluid in a 3D microchannel, finding a transition between active turbulence and regimes where there is a net flow al…
Binding self-propelled topological defects in active turbulence
Kristian Thijssen, Amin Doostmohammadi
We report on the emergence of stable self-propelled bound defects in monolayers of active nematics, which form virtual full-integer topological defects in the form of vortices and…
Active Inter-cellular Forces in Collective Cell Motility
Guanming Zhang, Romain Mueller, Amin Doostmohammadi +1
The collective behaviour of confluent cell sheets is strongly influenced both by polar forces, arising through cytoskeletal propulsion and by active inter-cellular forces, which ar…
Polar jets of swimming bacteria condensed by a patterned liquid crystal
Taras Turiv, Runa Koizumi, Kristian Thijssen +8
Active matter exhibits remarkable collective behavior in which flows, continuously generated by active particles, are intertwined with the orientational order of these particles. T…
Active matter in a viscoelastic environment
Emmanuel Lance Christopher VI M. Plan, Julia Yeomans, Amin Doostmohammadi
Active matter systems such as eukaryotic cells and bacteria continuously transform chemical energy to motion. Hence living systems exert active stresses on the complex environments…
