Ducted hydrokinetic turbines enhance energy-harvesting efficiency by better conditioning the flow to the blades, which may yield higher power output than conventional freestream turbines for the same reference area. In this work, we present a ducted

The Legacy Survey of Space and Time (LSST) at Vera C. Rubin Observatory is planned to begin in the Fall of 2025. The LSST survey cadence has been designed via a community-driven process regulated by the Survey Cadence Optimization Committee (SCOC), w

Conformal-in-the-Loop for Learning with Imbalanced Noisy Data

Autor: Graham-Knight, John Brandon, Fayyad, Jamil, Bayasi, Nourhan, Lasserre, Patricia, Najjaran, Homayoun

Class imbalance and label noise are pervasive in large-scale datasets, yet much of machine learning research assumes well-labeled, balanced data, which rarely reflects real world conditions. Existing approaches typically address either label noise or

The Hong-Ou-Mandel effect is really odd

Autor: Alsing, Paul M., Birrittella, Richard J., Gerry, Christopher C., Mimih, Jihane, Knight, Peter L.

When quantum state amplitudes interfere, surprising non-classical features emerge which emphasis the roles of indistinguishability and discreteness in quantum mechanics. A famous example in quantum optics is the Hong Ou Mandel interference effect,a m

Demonstration of Beyond Terabit/s/lambda Nonlinearity-free Transmission over the Hollow-core Fibre

Autor: Hong, Yang, Almonacil, Sylvain, Mardoyan, Haik, Carrero, Carina Castineiras, Osuna, Sergio, Gomez, Javier R., Knight, David R., Renaudier, Jeremie

We demonstrate nonlinearity-free transmission of Terabit/s/lambda PCS-64QAM signals through an HCF-based optical recirculating loop, which yields ~17.4% higher capacity than SMF-based loop under 23-dBm launch power (~13.5 dBm/channel) after 25 loops.
