Slowdown of Dune Migration in East Asia's Inland Deserts: A 35‐Year Response to Wind Stilling

Geophysical Research Letters, Volume 52, Issue 16, 28 August 2025.
Abstract Global terrestrial stilling, the recent decrease in near‐surface wind speeds, has significant environmental impacts, including reduced dust storms and vegetation recovery in East Asia's drylands. However, direct evidence of stilling effects on sand dunes is limited due to the lack of long‐term observational data.

Using Machine Learning to Improve Control for Confounding in the Dynamic Weighted Ordinary Least Squares Estimator of Optimal Adaptive Treatment Strategies

Biometrical Journal, Volume 67, Issue 4, August 2025.
ABSTRACT Estimating optimal adaptive treatment strategies (ATSs) can be done in several ways, including dynamic weighted ordinary least squares (dWOLS). This approach is doubly robust as it requires modeling both the treatment and the response, but only one of those models needs to be correctly specified to obtain a consistent estimator. For estimating

Detecting and Mapping Invasive Species Across Riparian Corridors via Object Detection Approaches in UAV Imagery: An Example of Impatiens glandulifera

Ecology and Evolution, Volume 15, Issue 8, August 2025.
Riparian zones in the United Kingdom are diverse but prone to anthropogenic changes and invasive species like impatiens glandulifera. This study introduces a method to identify and map these flowers using a computer vision framework and UAV imagery, wrapped into an executable program called the semi‐automatic thresholding tool (SATT). Validation showed

Research and Experimental Verification of the Dynamic Pose Analysis Method of Advanced Hydraulic Support in a Fully Mechanized Mining Face

Energy Science &Engineering, Volume 13, Issue 8, Page 3919-3934, August 2025.
The advanced hydraulic support is modeled as a closed‐loop 10‐degree‐of‐freedom robotic arm. Based on the improved D–H parameter method, forward kinematic analysis is performed under left and right column driving conditions, and a follower model is constructed considering mechanical constraints.
