Learning noisy tissue dynamics across time scales

Ming Han, John Devany, Michel Fruchart +2

Tissue dynamics play a crucial role in biological processes ranging from inflammation to morphogenesis. However, these noisy multicellular dynamics are notoriously hard to predict.…

Learning via mechanosensitivity and activity in cytoskeletal networks

Deb S. Banerjee, Martin J. Falk, Margaret L Gardel +3

In this work we show how a network inspired by a coarse-grained description of actomyosin cytoskeleton can learn - in a contrastive learning framework - from environmental perturba…

Motor crosslinking augments elasticity in active nematics

Steven A. Redford, Jonathan Colen, Jordan L. Shivers +8

In active materials, uncoordinated internal stresses lead to emergent long-range flows. An understanding of how the behavior of active materials depends on mesoscopic (hydrodynamic…

Measuring response functions of active materials from data

Mehdi Molaei, Steven A. Redford, Wen-hung Chou +4

From flocks of birds to biomolecular assemblies, systems in which many individual components independently consume energy to perform mechanical work exhibit a wide array of strikin…

Catapulting of topological defects through elasticity bands in active nematics

Nitin Kumar, Rui Zhang, Steven A. Redford +2

Active materials are those in which individual, uncoordinated local stresses drive the material out of equilibrium on a global scale. Examples of such assemblies can be seen across…

Machine learning active-nematic hydrodynamics

Jonathan Colen, Ming Han, Rui Zhang +10

Hydrodynamic theories effectively describe many-body systems out of equilibrium in terms of a few macroscopic parameters. However, such hydrodynamic parameters are difficult to der…

Nucleation and shape dynamics of model nematic tactoids around adhesive colloids

Nicholas B. Ludwig, Kimberly Weirich, Eli Alster +4

Recent experiments have shown how nematically-ordered tactoid shaped actin droplets can be reorganized and divided by the action of myosin molecular motors. In this paper, we consi…
