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 […]
Kavli Affiliate: Ariel Amir | First 5 Authors: Yipei Guo, Ariel Amir, , , | Summary: Homeostasis of protein concentrations in cells is crucial for their proper functioning, and this requires concentrations (at their steady-state levels) to be stable to fluctuations. Since gene expression is regulated by proteins such as transcription factors (TFs), the full […]
Kavli Affiliate: Shmuel M. Rubinstein | First 5 Authors: Jovana Andrejevic, Lisa M. Lee, Shmuel M. Rubinstein, Chris H. Rycroft, | Summary: As a confined thin sheet crumples, it spontaneously segments into flat facets delimited by a network of ridges. Despite the apparent disorder of this process, statistical properties of crumpled sheets exhibit striking reproducibility. […]
Kavli Affiliate: Robert J. Wood | First 5 Authors: Kaushik Jayaram, Jennifer Shum, Samantha Castellanos, E. Farrell Helbling, Robert J. Wood | Summary: Here we present HAMR-Jr, a SI{22.5}{millimeter}, SI{320}{milligram} quadrupedal microrobot. With eight independently actuated degrees of freedom, HAMR-Jr is, to our knowledge, the most mechanically dexterous legged robot at its scale and is […]
