Human Eye Visualization With an Attention Mechanism: Enhancing Flower Detection and Classification With Visual Attention and Photometric Principles Inspired by Human Vision

Engineering Reports, Volume 8, Issue 3, March 2026.
The graphical abstract illustrates a flower classification model relying on the human visual system. The model captures images, simulates visual attention and photometric perception, extracts features of shape and color, and classifies flowers by using an optimized neural network that enhances recognition accuracy by mimicking the human eye's focusing ...

A Novel Non-Stationary Clutter Suppression Approach for Space-Based Early Warning Radar Using an Interpulse Multi-Frequency Mode

Remote Sensing
The non-stationary clutter of space-based early warning radar (SBEWR) is more serious than that of airborne early warning radar. This phenomenon is primarily attributed to the Earth’s rotation and range ambiguity.

Radar Maxima: Calibrated Area‐Based Probabilistic Forecasts for Heavy Precipitation

Meteorological Applications, Volume 33, Issue 2, March/April 2026.
Radar Maxima is a calibrated area‐based probabilistic forecast product for heavy precipitation. Radar precipitation within 40 km neighbourhoods is aggregated to statistically upscale ICON‐D2‐EPS. The product is designed to overcome inherent limitations of point‐based forecasts, which often yield low probabilities for extreme events. ABSTRACT We present,
