Epidemic Management and Control Through Risk-Dependent Individual Contact Interventions

Kavli Affiliate: Chiara Daraio | First 5 Authors: Tapio Schneider, Oliver R. A. Dunbar, Jinlong Wu, Lucas Böttcher, Dmitry Burov | Summary: Testing, contact tracing, and isolation (TTI) is an epidemic management and control approach that is difficult to implement at scale. Here we demonstrate a scalable improvement to TTI that uses data assimilation (DA) […]

Quantum Criticality Using a Superconducting Quantum Processor

Kavli Affiliate: Joel E. Moore | First 5 Authors: Maxime Dupont, Joel E. Moore, , , | Summary: Quantum criticality emerges from the collective behavior of many interacting quantum particles, often at the transition between different phases of matter. It is one of the cornerstones of condensed matter physics, which we access on noisy intermediate-scale […]

Signatures of visuospatial information foraging during learning of complex environments

Kavli Affiliate: Daphna Shohamy | Authors: David L Barack, Akram Bakkour, Daphna Shohamy and C Daniel Salzman | Summary: Abstract In the real world, making sequences of decisions to achieve goals often depends upon the ability to learn aspects of the environment that are not directly perceptible. Learning these so-called latent features requires seeking information […]

Anomalous elasticity of cellular tissue vertex model

Kavli Affiliate: Mark J. Bowick | First 5 Authors: Arthur Hernandez, Michael F. Staddon, Mark J. Bowick, M. Cristina Marchetti, Michael Moshe | Summary: Vertex Models, as used to describe cellular tissue, have an energy controlled by deviations of each cell area and perimeter from target values. The constrained nonlinear relation between area and perimeter […]

Geometric rigidity and anomalous elasticity of cellular tissue vertex model

Kavli Affiliate: Mark J. Bowick | First 5 Authors: Arthur Hernandez, Michael F. Staddon, Mark J. Bowick, M. Cristina Marchetti, Michael Moshe | Summary: Vertex Models, as used to describe cellular tissue, have an energy controlled by deviations from both a target area and a target perimeter. The constrained nonlinear relation between area and perimeter, […]

Formation and evolution of young massive clusters in galaxy mergers: the SMUGGLE view

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Hui Li, Mark Vogelsberger, Greg L. Bryan, Federico Marinacci, Laura V. Sales | Summary: Galaxy mergers are known to host abundant young massive cluster (YMC) populations, whose formation mechanism is still not well-understood. Here, we present a high-resolution galaxy merger simulation with explicit star formation and stellar […]
