The Oxygen Reduction Pathway for Spinel Metal Oxides in Alkaline Media: An Experimentally Supported Ab Initio Study

Posted by dbos Cornell

Kavli Affiliate: Hector D. Abruna | First 5 Authors: Colin R. Bundschu, Mahdi Ahmadi, Juan F. Méndez-Valderrama, Yao Yang, Héctor D. Abruña | Summary: Precious-metal-free spinel oxide electrocatalysts are promising candidates for catalyzing the oxygen reduction reaction (ORR) in alkaline fuel cells. In this theory-driven study, we use joint density-functional theory in tandem with supporting […]

Contrast Everything: A Hierarchical Contrastive Framework for Medical Time-Series

Posted by dbos Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Yihe Wang, Yu Han, Haishuai Wang, Xiang Zhang, | Summary: Contrastive representation learning is crucial in medical time series analysis as it alleviates dependency on labor-intensive, domain-specific, and scarce expert annotations. However, existing contrastive learning methods primarily focus on one single data level, which fails to fully […]

Low energy electrodynamics and a hidden Fermi liquid in the heavy-fermion CeCoIn$_5$

Posted by dbos Cornell

Kavli Affiliate: Darrell G. Schlom | First 5 Authors: L. Y. Shi, Zhenisbek Tagay, Jiahao Liang, Khoan Duong, Yi Wu | Summary: We present time-domain THz spectroscopy of thin films of the heavy-fermion superconductor CeCoIn$_5$. The complex optical conductivity is analyzed through a Drude model and extended Drude model analysis. Below the $approx$ 40 K […]
