ECL: Class-Enhancement Contrastive Learning for Long-tailed Skin Lesion Classification

Kavli Affiliate: Ke Wang | First 5 Authors: Yilan Zhang, Jianqi Chen, Ke Wang, Fengying Xie, | Summary: Skin image datasets often suffer from imbalanced data distribution, exacerbating the difficulty of computer-aided skin disease diagnosis. Some recent works exploit supervised contrastive learning (SCL) for this long-tailed challenge. Despite achieving significant performance, these SCL-based methods focus […]

JWST reveals excess cool water near the snowline in compact disks, consistent with pebble drift

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Andrea Banzatti, Klaus M. Pontoppidan, John Carr, Evan Jellison, Ilaria Pascucci | Summary: Previous analyses of mid-infrared water spectra from young protoplanetary disks observed with the Spitzer-IRS found an anti-correlation between water luminosity and the millimeter dust disk radius observed with ALMA. This trend was suggested […]

The Radial Distribution and Excitation of H2 around Young Stars in the HST-ULLYSES Survey

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Kevin France, Nicole Arulanantham, Erin Maloney, P. Wilson Cauley, P. Abraham | Summary: The spatial distribution and evolution of gas in the inner 10 au of protoplanetary disks form the basis for estimating the initial conditions of planet formation. Among the most important constraints derived from […]

Photometric observations of flares on AD Leo from GWAC-F30 and TESS

Kavli Affiliate: Jing Wang | First 5 Authors: Jian-Ying Bai, Jing Wang, Hua-Li Li, Li-Ping Xin, Guang-Wei Li | Summary: We observed active M dwarf star AD Leo for 146 hr in photometry by GWAC-F30 and also analyzed 528-hr photometric data of the star from TESS. A total of 9 and 70 flares are detected […]
