Domain Adaptation for Measurements of Strong Gravitational Lenses

Posted by dbos November 28, 2023December 11, 2023Chicago

Kavli Affiliate: Brian Nord | First 5 Authors: [#item_custom_name[1]], [#item_custom_name[2]], [#item_custom_name[3]], [#item_custom_name[4]], [#item_custom_name[5]] | Summary: Upcoming surveys are predicted to discover galaxy-scale strong lenses on the order of $10^5$, making deep learning methods necessary in lensing data analysis. Currently, there is insufficient real lensing data to train deep learning algorithms, but the alternative of training […]

Predicting the Age of Astronomical Transients from Real-Time Multivariate Time Series

Posted by dbos November 28, 2023MIT

Kavli Affiliate: Michael Fausnaugh | First 5 Authors: Hali Huang, Daniel Muthukrishna, Prajna Nair, Zimi Zhang, Michael Fausnaugh | Summary: Astronomical transients, such as supernovae and other rare stellar explosions, have been instrumental in some of the most significant discoveries in astronomy. New astronomical sky surveys will soon record unprecedented numbers of transients as sparsely […]

Optimal control of interacting active particles on complex landscapes

Posted by dbos November 28, 2023December 11, 2023Harvard

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 […]

A Geometric Tension Dynamics Model of Epithelial Convergent Extension

Posted by klaurent November 28, 2023UCSB

Kavli Affiliate: Boris I. Shraiman | Summary:Convergent extension of epithelial tissue is a key motif of animal morphogenesis. On a coarse scale, cell motion resembles laminar fluid flow; yet in contrast to a fluid, epithelial cells adhere to each other and maintain the tissue layer under actively generated internal tension. To resolve this apparent paradox, […]
