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 […]

Context-Aware Abbreviation Expansion Using Large Language Models

Kavli Affiliate: Michael P. Brenner | First 5 Authors: Shanqing Cai, Subhashini Venugopalan, Katrin Tomanek, Ajit Narayanan, Meredith R. Morris | Summary: Motivated by the need for accelerating text entry in augmentative and alternative communication (AAC) for people with severe motor impairments, we propose a paradigm in which phrases are abbreviated aggressively as primarily word-initial […]

Safe Bayesian Optimization using Interior-Point Methods — Applied to Personalized Insulin Dose Guidance

Kavli Affiliate: Francis J. Doyle | First 5 Authors: Dinesh Krishnamoorthy, Francis J. Doyle III, , , | Summary: This paper considers the problem of Bayesian optimization for systems with safety-critical constraints, where both the objective function and the constraints are unknown, but can be observed by querying the system. In safety-critical applications, querying the […]

Energy transfer and vortex structures: Visualizing the incompressible turbulent energy cascade

Kavli Affiliate: Michael P. Brenner | First 5 Authors: Ryan McKeown, Alain Pumir, Shmuel M. Rubinstein, Michael P. Brenner, Rodolfo Ostilla-Mónico | Summary: The transfer of kinetic energy from large to small scales is a hallmark of turbulent flows. Yet, a precise mechanistic description of this transfer, which is expected to occur via an energy […]

How to grow a flat leaf

Kavli Affiliate: L. Mahadevan | First 5 Authors: Salem al-Mosleh, L. Mahadevan, , , | Summary: Growing a flat lamina such as a leaf is almost impossible without some feedback to stabilize long wavelength modes that are easy to trigger since they are energetically cheap. Here we combine the physics of thin elastic plates with […]

$Rheomergy$: Collective behavior mediated by active flow-based recruitment

Kavli Affiliate: L. Mahadevan | First 5 Authors: S Ganga Prasath, L Mahadevan, , , | Summary: The physics of signal propagation in a collection of organisms that communicate with each other both enables and limits how active excitations at the individual level reach, recruit and lead to collective patterning. Inspired by the patterns in […]

Universal catastrophe time distributions of dynamically unstable polymers

Kavli Affiliate: Ariel Amir | First 5 Authors: Paul B. Dieterle, Jenny Zheng, Ethan Garner, Ariel Amir, | Summary: Dynamic instability — the growth, catastrophe, and shrinkage of quasi-one-dimensional filaments — has been observed in multiple biopolymers. Scientists have long understood the catastrophic cessation of growth and subsequent depolymerization as arising from the interplay of […]
