Kavli Affiliate: Daniel J. Needleman | First 5 Authors: Sebastian Fürthauer, Daniel J Needleman, Michael J. Shelley, , | Summary: 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 and that act as motors to do mechanical […]
Kavli Affiliate: Katia Bertoldi | First 5 Authors: Gabriele Librandi, Eleonora Tubaldi, Katia Bertoldi, , | Summary: Nonreciprocity can be passively achieved by harnessing material nonlinearities. In particular, networks of nonlinear bistable elements with asymmetric energy landscapes have recently been shown to support unidirectional transition waves. However, in these systems energy can be transferred only […]
Kavli Affiliate: Vinothan N. Manoharan | First 5 Authors: Victoria Hwang, Anna B. Stephenson, Solomon Barkley, Soeren Brandt, Ming Xiao | Summary: Disordered nanostructures with correlations on the scale of visible wavelengths can show angle-independent structural colors. These materials could replace dyes in some applications because the color is tunable and resists photobleaching. However, designing […]

Kavli Affiliate: Katia Bertoldi | First 5 Authors: Lishuai Jin, Antonio Elia Forte, Bolei Deng, Ahmad Rafsanjani, Katia Bertoldi | Summary: Kirigami, the Japanese art of paper cutting, has recently enabled the design of stretchable mechanical metamaterials that can be easily realized by embedding arrays of periodic cuts into an elastic sheet. Here, we exploit […]
Kavli Affiliate: Michael Brenner | First 5 Authors: Arunachalam Narayanaswamy, Subhashini Venugopalan, Dale R. Webster, Lily Peng, Greg Corrado | Summary: Model explanation techniques play a critical role in understanding the source of a model’s performance and making its decisions transparent. Here we investigate if explanation techniques can also be used as a mechanism for […]

Kavli Affiliate: Shmuel M. Rubinstein | First 5 Authors: Sam Dillavou, Yohai Bar Sinai, Michael P Brenner, Shmuel M Rubinstein, | Summary: Classically, the quantity of contact area $A_R$ between two bodies is considered a proxy for the force of friction. However, bond density across the interface – quality of contact – is also relevant, […]
Kavli Affiliate: David A. Weitz | First 5 Authors: Andrea Montessori, Marco Lauricella, Sauro Succi, Elad Stolovicki, David A. Weitz | Summary: Three-dimensional, time-dependent direct simulations of step emulsification micro-devices highlight two essential mechanisms for droplet formation: first, the onset of an adverse pressure gradient driving a back-flow of the continuous phase from the external […]
Kavli Affiliate: Daniel Needleman | First 5 Authors: Brian D. Leahy, Won-Dong Jang, Helen Y. Yang, Robbert Struyven, Donglai Wei | Summary: A major challenge in clinical In-Vitro Fertilization (IVF) is selecting the highest quality embryo to transfer to the patient in the hopes of achieving a pregnancy. Time-lapse microscopy provides clinicians with a wealth […]
