Real‐Time High‐Definition Hyperspectral Endoscopy via Spatial‐Temporal Low‐Frequency‐Stochastic Spectral Encoding

Advanced Science, Volume 13, Issue 16, 18 March 2026.
A real‐time, high‐definition hyperspectral endoscopy is enabled by developing a spatial‐temporal spectral encoding approach based on low‐frequency stochastic filters combined with an encoding‐guided attention network. It provides hyperspectral image of in vivo tissue with fine superficial features, enables visualization of rapid and subtle ...

Association of Abatacept With Lower Mortality Risk Compared to Rituximab in Rheumatoid Arthritis–Associated Interstitial Lung Disease: An Emulated Target Trial

Arthritis &Rheumatology, Volume 78, Issue 3, Page 592-602, March 2026.
Objective The optimal treatment strategy for rheumatoid arthritis–associated interstitial lung disease (RA‐ILD) remains uncertain, and direct comparative data between biologics are limited. This study aimed to evaluate the effectiveness and safety of abatacept compared with rituximab in patients with RA‐ILD.

An Automated Data Efficient Morphometric Approach to Define Global Lentic and Lotic Inland Waters

Water Resources Research, Volume 62, Issue 1, January 2026.
Abstract Defining lentic and lotic system types is critical for understanding hydrological, ecological, and biochemical processes. Traditional classification methods rely on non‐generalizable site‐specific parameters such as visual characteristics, historical inventory, and residence time.
