Collective phototactic robotectonics

Kavli Affiliate: L. Mahadevan | First 5 Authors: Fabio Giardina, S Ganga Prasath, L Mahadevan, , | Summary: Cooperative task execution, a hallmark of eusociality, is enabled by local interactions between the agents and the environment through a dynamically evolving communication signal. Inspired by the collective behavior of social insects whose dynamics is modulated by […]

Predicting the structural colors of films of disordered photonic balls

Kavli Affiliate: Vinothan N. Manoharan | First 5 Authors: Anna B. Stephenson, Ming Xiao, Victoria Hwang, Liangliang Qu, Paul A. Odorisio | Summary: Photonic balls are spheres tens of micrometers in diameter containing assemblies of nanoparticles or nanopores with a spacing comparable to the wavelength of light. When these nanoscale features are disordered, but still […]

Learning to correct spectral methods for simulating turbulent flows

Kavli Affiliate: Michael P. Brenner | First 5 Authors: Gideon Dresdner, Dmitrii Kochkov, Peter Norgaard, Leonardo Zepeda-Núñez, Jamie A. Smith | Summary: Despite their ubiquity throughout science and engineering, only a handful of partial differential equations (PDEs) have analytical, or closed-form solutions. This motivates a vast amount of classical work on numerical simulation of PDEs […]

How Material Heterogeneity Creates Rough Fractures

Kavli Affiliate: Shmuel M. Rubinstein | First 5 Authors: Will Steinhardt, Shmuel M. Rubinstein, , , | Summary: Fractures are a critical process in how materials wear, weaken, and fail whose unpredictable behavior can have dire consequences. While the behavior of smooth cracks in ideal materials is well understood, it is assumed that for real, […]

Global Reduction in Ship-tracks from Sulfur Regulations for Shipping Fuel

Kavli Affiliate: Robert Wood | First 5 Authors: Tianle Yuan, Hua Song, Robert Wood, Chenxi Wang, Lazaros Oreopoulos | Summary: Ship-tracks are produced by ship-emitted aerosols interacting with marine low clouds. Here we apply deep learning models on satellite data to produce the first multi-year global climatology map of ship-tracks. We show that ship-tracks are […]

Pressure-induced Shape-shifting of Helical Bacteria

Kavli Affiliate: Ariel Amir | First 5 Authors: Cesar L. Pastrana, Luyi Qiu, Shahaf Armon, Ulrich Gerland, Ariel Amir | Summary: Many bacterial species are helical in form, including the widespread pathogen H. pylori. Motivated by recent experiments on H. pylori showing that cell wall synthesis is not uniform, we investigate the possible formation of […]
