Adaptive Prototype‐Based Few‐Shot Segmentation for Debris Flow Early Warning

Journal of Flood Risk Management, Volume 19, Issue 4, December 2026.
From single‐parameter monitoring to a cross‐modal few‐shot visual paradigm for debris flow early warning. Conventional rainfall‐gauge and mud‐level monitoring is data‐sparse, delayed in response, and spatially limited. The proposed framework instead fuses a support set, a query image, and a textual target category through ResNet‐50 and CLIP encoders ...

Carbon‐Based Adsorbents for CO2 Capture: Mechanism‐Guided Material Design and Data‐Driven Optimization

Carbon Neutralization, Volume 5, Issue 6, November 2026.
The main purpose of this review is to summarize recent progress in the broad family of carbon‐based materials and their derivatives for CO2 capture. Rather than focusing on a single precursor or modification route, it examines pristine carbon adsorbents, functionalized carbon derivatives, and carbon‐based composites within a unified framework.

The Staggered SAR concept: Imaging a wide continuous swath with high resolution [PDF]

, 2013
Staggered SAR is an innovative synthetic aperture radar (SAR) concept, based on the continuous variation of the pulse repetition interval (PRI). This concept allows high-resolution imaging of a wide continuous swath without the need for a long antenna ...
