Self-organized intracellular twisters
Sayantan Dutta, Reza Farhadifar, Wen Lu +7
Life in complex systems, such as cities and organisms, comes to a standstill when global coordination of mass, energy, and information flows is disrupted. Global coordination is no…
Spectrally accurate solutions to inhomogeneous elliptic PDE in smooth geometries using function intension
David B. Stein
We present a spectrally accurate embedded boundary method for solving linear, inhomogeneous, elliptic partial differential equations (PDE) in general smooth geometries, focusing in…
Thermodynamically consistent coarse-graining of polar active fluids
Scott Weady, David B. Stein, Michael J. Shelley
We introduce a closure model for coarse-grained kinetic theories of polar active fluids. Based on a quasi-equilibrium approximation of the particle distribution function, the model…
A fast Chebyshev method for the Bingham closure with application to active nematic suspensions
Scott Weady, Michael J. Shelley, David B. Stein
Continuum kinetic theories provide an important tool for the analysis and simulation of particle suspensions. When those particles are anisotropic, the addition of a particle orien…
Hyperuniformity and phase enrichment in vortex and rotor assemblies
Naomi Oppenheimer, David B. Stein, Matan Yah Ben Zion +1
Ensembles of particles rotating in a two-dimensional fluid can exhibit chaotic dynamics yet develop signatures of hidden order. Such "rotors" are found in the natural world spannin…
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…
