Cooperative effect of local active stresses on the macroscopic contractility of elastic fiber networks
Abhinav Kumar, David A. Quint, Kinjal Dasbiswas
The collective action of actively contractile units embedded in elastic biopolymer networks plays a crucial role in regulating the network's macroscopic mechanical response. Here,…
Range and strength of mechanical interactions of force dipoles in elastic fiber networks
Abhinav Kumar, David A. Quint, Kinjal Dasbiswas
Mechanical forces generated by myosin II molecular motors drive diverse cellular processes, most notably shape change, division and locomotion. These forces may be transmitted over…
Geometric effects induce anomalous size-dependent active transport in structured environments
Pooja Chopra, David Quint, Ajay Gopinathan +1
Variations of transport efficiency in structured environments between distinct individuals in actively self-propelled systems is both hard to study and poorly understood. Here, we…
Shape selection of surface-bound helical filaments: biopolymers on curved membranes
D. A. Quint, A. Gopinathan, G. M. Grason
Motivated to understand the behavior of biological filaments interacting with membranes of various types, we study a theoretical model for the shape and thermodynamics of intrinsic…
Rigid cluster decomposition reveals criticality in frictional jamming
Silke Henkes, David A. Quint, Y. Fily +1
We study the nature of the frictional jamming transition within the framework of rigidity percolation theory. Slowly sheared frictional packings are decomposed into rigid clusters…
Conformational Collapse of Surface-Bound Helical Filaments
David A. Quint, Ajay Gopinathan, Gregory M. Grason
Chiral polymers are ubiquitous in nature and in the cellular context they are often found in association with membranes. Here we show that surface bound polymers with an intrinsic…
Redundancy and cooperativity in the mechanics of compositely crosslinked filamentous networks
Moumita Das, D. A. Quint, J. M. Schwarz
The actin cytoskeleton in living cells has many types of crosslinkers. The mechanical interplay between these different crosslinker types is an open issue in cytoskeletal mechanics…
