Optimal control of interacting active particles on complex landscapes

Kavli Affiliate: L. Mahadevan | First 5 Authors: Sumit Sinha, Vishaal Krishnan, L Mahadevan, , | Summary: Active many-body systems composed of many interacting degrees of freedom often operate out of equilibrium, giving rise to non-trivial emergent behaviors which can be functional in both evolved and engineered contexts. This naturally suggests the question of control […]

Gene expression in growing cells: A biophysical primer

Kavli Affiliate: Ariel Amir | First 5 Authors: Ido Golding, Ariel Amir, , , | Summary: Cell growth and gene expression, essential elements of all living systems, have long been the focus of biophysical interrogation. Advances in single-cell methods have invigorated theoretical studies into these processes. However, until recently, there was little dialog between the […]

Neural General Circulation Models

Kavli Affiliate: Michael P. Brenner | First 5 Authors: Dmitrii Kochkov, Janni Yuval, Ian Langmore, Peter Norgaard, Jamie Smith | Summary: General circulation models (GCMs) are the foundation of weather and climate prediction. GCMs are physics-based simulators which combine a numerical solver for large-scale dynamics with tuned representations for small-scale processes such as cloud formation. […]

Emergent collective motion of self-propelled condensate droplets

Kavli Affiliate: Joanna Aizenberg | First 5 Authors: Marcus Lin, Philseok Kim, Sankara Arunachalam, Rifan Hardian, Solomon Adera | Summary: Recently, there is much interest in droplet condensation on soft or liquid/liquid-like substrates. Droplets can deform soft and liquid interfaces resulting in a wealth of phenomena not observed on hard, solid surfaces (e.g., increased nucleation, […]

The Temporal Structure of Language Processing in the Human Brain Corresponds to The Layered Hierarchy of Deep Language Models

Kavli Affiliate: Michael Brenner | First 5 Authors: Ariel Goldstein, Eric Ham, Mariano Schain, Samuel Nastase, Zaid Zada | Summary: Deep Language Models (DLMs) provide a novel computational paradigm for understanding the mechanisms of natural language processing in the human brain. Unlike traditional psycholinguistic models, DLMs use layered sequences of continuous numerical vectors to represent […]

Entanglement transition in rod packings

Kavli Affiliate: L. Mahadevan | First 5 Authors: Yeonsu Jung, Thomas Plumb-Reyes, Hao-Yu Greg Lin, L. Mahadevan, | Summary: Random packings of stiff rods are self-supporting mechanical structures stabilized by their geometrical and topological complexity. To understand why, we deploy X-ray computerized tomography to unveil the structure of the packing. This allows us to define […]
