Monitoring Near‐Surface Changes Using Anthropogenic Seismic Vibrations

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract The abundance of anthropogenic seismic noise provides a valuable resource for monitoring dynamic subsurface property changes. We utilize railway and wind turbine‐induced vibrations recorded by a geophone array to estimate surface wave attenuation and velocity in the underlying glacial deposits of Illinois.

EOF‐Based Bias Correction of Near‐Surface Wind Speed Over China Reveals Stronger Future Trends and Variability

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract As near‐surface wind speed (NSWS) largely controls wind power generation, robust projection is vital to wind energy planning and broader sustainability goals. However, the predictive skill of climate models for NSWS remains uncertain. Analysis of Coupled Model Intercomparison Project Phase 6 simulations shows that the models reproduce the mean

Water‐Borne Erosion of Reinforced Polymer Composites: Application to Shallow Offshore Marine Environment

Polymer Composites, Volume 47, Issue 5, Page 4102-4126, 10 March 2026.
Comparison of experimental and model‐predicted erosion rates for carbon fibre‐reinforced polymer (CFRP) and glass fibre‐reinforced polymer (GFRP) under low‐velocity (2 m/s) and at varying angles and sand concentrations (0.0, 0.05, 0.4 g/L). The results demonstrate good agreement between experimental data and model predictions across different erosive ...

Engineering Deformation and Failure in Diamond Triply Periodic Minimal Surface Lattices via 3D Wall‐Thickness Grading

Advanced Engineering Materials, Volume 28, Issue 5, 4 March 2026.
The work demonstrates that strategic wall‐thickness grading in diamond triply periodic minimal surface lattices enables precise tuning of deformation and failure behavior under compression. Different gradation patterns guide how and where the structure collapses, improving energy absorption or promoting controlled brittle failure.
