MambaShadowDet: A High-Speed and High-Accuracy Moving Target Shadow Detection Network for Video SAR

open access: yesRemote Sensing
Existing convolution neural network (CNN)-based video synthetic aperture radar (SAR) moving target shadow detectors are difficult to model long-range dependencies, while transformer-based ones often suffer from greater complexity. To handle these issues,

Remote sensing and geospatial analysis for the study of plant community regeneration in human‐modified landscapes

open access: yesEcosphere, Volume 17, Issue 3, March 2026.
Abstract Natural regeneration is essential for maintaining functionally diverse and resilient plant communities in human‐modified landscapes. To design and implement successful conservation and restoration initiatives in these landscapes, research on the environmental and anthropogenic drivers of natural regeneration must be scaled up beyond ...

Prioritized Real‐Time UAV‐Based Vessel Detection for Efficient Maritime Search

open access: yesJournal of Field Robotics, Volume 43, Issue 2, Page 561-577, March 2026.
ABSTRACT Real‐time vessel detection in maritime environments is crucial for diverse applications requiring speed and accuracy. Static camera views often introduce blind spots, compromising detection efficiency. This paper proposes a novel, real‐time UAV‐based system that uses a dynamic camera control strategy to address this limitation.

Supershear Transitions and Bilateral Asymmetric Rupture of the 2025 Sagaing (Myanmar) Earthquake Revealed by Geodetic and Seismic Observations

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract The Sagaing Fault (SF) accommodates major plate motion in Myanmar, yet large earthquakes along it have rarely been captured by modern geodetic and seismic observations. The 2025 Sagaing earthquake generated an exceptionally long rupture (∼535 km), offering a rare opportunity to investigate rupture dynamics along continental transform fault. We
