Lévy Walks and Path Chaos in the Dispersal of Elongated Structures Moving across Cellular Vortical Flows
Shi-Yuan Hu, Jun-Jun Chu, Michael J. Shelley +1
In cellular vortical flows, namely arrays of counter-rotating vortices, short but flexible filaments can show simple random walks through their stretch-coil interactions with flow…
Comparison of explicit and mean-field models of cytoskeletal filaments with crosslinking motors
Adam R. Lamson, Jeffrey M. Moore, Fang Fang +3
In cells, cytoskeletal filament networks are responsible for cell movement, growth, and division. Filaments in the cytoskeleton are driven and organized by crosslinking molecular m…
A design framework for actively crosslinked filament networks
Sebastian Fürthauer, Daniel J Needleman, Michael J. Shelley
Living matter moves, deforms, and organizes itself. In cells this is made possible by networks of polymer filaments and crosslinking molecules that connect filaments to each other…
Swirling Instability of the Microtubule Cytoskeleton
David B. Stein, Gabriele De Canio, Eric Lauga +2
In the cellular phenomena of cytoplasmic streaming, molecular motors carrying cargo along a network of microtubules entrain the surrounding fluid. The piconewton forces produced by…
Metallic Microswimmers Driven up the Wall by Gravity
Quentin Brosseau, Florencio Balboa Usabiaga, Enkeleida Lushi +5
As a natural and functional behavior, various microorganisms exhibit gravitaxis by orienting and swimming upwards against gravity. Swimming autophoretic nanomotors described herein…
A stable and accurate scheme for solving the Stefan problem coupled with natural convection using the Immersed Boundary Smooth Extension method
Jinzi Mac Huang, Michael J. Shelley, David B. Stein
The dissolution of solids has created spectacular geomorphologies ranging from centimeter-scale cave scallops to the kilometer-scale "stone forests" of China and Madagascar. Mathem…
