Leveraging the next generation of spaceborne Earth observations for fuel monitoring and wildland fire management

Remote Sensing in Ecology and Conservation, Volume 11, Issue 2, Page 133-155, April 2025.
This paper presents an interdisciplinary perspective of the next generation of spaceborne remote sensors applied to wildland fire management. We highlight the potential improvements in fuel characterization at large scale arising from the use of new spaceborne instruments with near‐global, freely‐available data.

Relationship Between Plant Diversity and Soil Environment in Karst Urban Remnant Mountains: A Comparative Analysis of Two Types

Ecology and Evolution, Volume 15, Issue 3, March 2025.
The transformation of karst urban remnant mountains into mountain parks had not only simplified the composition of plant species and reduced biodiversity, but also changed the characteristics of soil environmental factors and their distribution pattern with plant diversity, thus reshaping their mutual relationship.

Improved SAR Aircraft Detection Algorithm Based on Visual State Space Models

IET Computer Vision, Volume 19, Issue 1, January/December 2025.
This paper aims to effectively alleviate the issues of false detections and missed detections in SAR aircraft detection tasks, thereby significantly improving detection accuracy. We innovatively propose a novel SSM‐based detection algorithm, MSAD. Leveraging the advantages of linear computational complexity with SSM, this method can maintain efficient ...

Military Aircraft Recognition Method Based on Attention Mechanism in Remote Sensing Images

IET Image Processing, Volume 19, Issue 1, January/December 2025.
First, the TripletAttention attention module is used in the neck network, which captures cross‐ dimensional interactions and utilises a three‐branch structure to calculate attention weights. This further enhances the network's ability to preserve details and restore colours in the process of image fusion.
