A Machine Learning Approach to Robustly Determine Director Fields and Analyze Defects in Active Nematics

Autor: Li, Yunrui, Zarei, Zahra, Tran, Phu N., Wang, Yifei, Baskaran, Aparna, Fraden, Seth, Hagan, Michael F., Hong, Pengyu

Active nematics are dense systems of rodlike particles that consume energy to drive motion at the level of the individual particles. They exist in natural systems like biological tissues and artificial materials such as suspensions of self-propelled

From Disks to Channels: Dynamics of Active Nematics Confined to an Annulus

Autor: Joshi, Chaitanya, Zarei, Zahra, Norton, Michael M., Fraden, Seth, Baskaran, Aparna, Hagan, Michael F.

Confinement can be used to systematically tame turbulent dynamics occurring in active fluids. Although periodic channels are the simplest geometries to study confinement numerically, the corresponding experimental realizations require closed racetrac

Light-activated microtubule-based 2D active nematic

Autor: Zarei, Zahra, Berezney, John, Hensley, Alexander, Lemma, Linnea, Senbil, Nesrin, Dogic, Zvonimir, Fraden, Seth

We characterize two-dimensional (2D) microtubule-based active nematics driven by light-responsive kinesin motor clusters. We assess two constructs of optogenetic kinesin: opto-K401, a processive motor, and opto-K365, a non-processive motor. Measureme
