Mechanics of heterogeneous fiber networks
Kyu Hwan Choi, Sattvic Ray, Reef Sweeney +2
Internally generated active stresses drive soft materials into architectures inaccessible to thermal self-assembly. We use a microtubule-based active fluid to assemble and irrevers…

Active assembly and non-reciprocal dynamics of elastic membranes
John Berezney, Sattvic Ray, Itamar Kolvin +6
Equilibrium self-assembly and conventional materials processing techniques fall far short of mimicking dynamic self-actuating processes that are commonplace throughout biology. To…

Deep-learning Optical Flow Outperforms PIV in Obtaining Velocity Fields from Active Nematics
Phu N. Tran, Sattvic Ray, Linnea Lemma +6
Deep learning-based optical flow (DLOF) extracts features in adjacent video frames with deep convolutional neural networks. It uses those features to estimate the inter-frame motio…
