From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

open access: yesJournal of Field Robotics, Volume 43, Issue 7, Page 4475-4514, October 2026.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

A Novel Non‐Torque Dynamic Load Decoupling Method for Large Wind Turbine Nacelle Test Bench

open access: yesWind Energy, Volume 29, Issue 10, October 2026.
ABSTRACT Accurate reproduction of non‐torque dynamic loads is a key challenge for full‐scale wind turbine nacelle test benches, where the nacelle‐level drivetrain is validated under controlled multi‐degree‐of‐freedom mechanical loading. This study focuses on the shaft‐conjugate load application unit (LAU) adopted in the 25‐MW‐class full‐scale wind ...

A Multi‐Analytical Approach for the Compositional Characterization and Chronological Discrimination of Benin (Nigeria) Metal Sculptures

open access: yesArchaeometry, Volume 68, Issue 5, Page 1022-1036, October 2026.
ABSTRACT This study presents a multi‐analytical archaeometric approach for the compositional characterization and chronological discrimination of Benin metal sculptures in relation to the 1897 Punitive Expedition. The methodology integrates elemental composition (XRF and ICP), stable lead isotope ratios (MC‐ICP‐MS) for alloy system characterization ...

Management of Massive Post‐Tracheostomy Subcutaneous Emphysema With an Adjustable‐Length, Wire‐Reinforced Tracheostomy Tube: A Case Report

open access: yesClinical Case Reports, Volume 14, Issue 9, September 2026.
ABSTRACT Massive subcutaneous emphysema with pneumomediastinum is a rare but potentially life‐threatening complication following tracheostomy, for which standardized management strategies are lacking. We report the case of a 67‐year‐old man who developed progressive cervicofacial and thoracic subcutaneous emphysema on postoperative Day 9 after an ...
