An Eyeball‐Movement‐Inspired Multi‐DOF Miniature Piezoelectric Actuator with Strong Load‐Driving Capability

Advanced Intelligent Systems, Volume 7, Issue 10, October 2025.
Inspired by the eye movements of humans, a multi‐degree‐of‐freedom (multi‐DOF) miniature piezoelectric actuator with a square‐circular ring structure is proposed. The actuator demonstrates a well‐balanced performance in miniaturization, operational efficiency, actuation precision, and load‐driving capability.

U-NET-based deep learning for automated detection of lathe checks in homogeneous wood veneers

European Journal of Wood and Wood Products
Abstract Automated detection of lathe checks in wood veneers presents significant challenges due to their variability and the natural properties of wood. This study explores the use of two convolutional neural networks (U-Net architecture) to enhance the precision and efficiency of lathe checks detection in poplar veneers.

Anomaly Detection Method for Hybrid Workpieces Using Dynamic Time Warping

Advanced Engineering Materials, Volume 27, Issue 16, August 2025.
Monitoring of hybrid workpieces: when machining hybrid workpieces, unavoidable axial deviations of the material transition zone cause temporal shifts in the process force signals. A new anomaly detection method based on dynamic time warping is proposed to detect material defects.

Label‐Free 3D Photoacoustic Imaging of Tumor Organoids for Volumetric Drug Screening

Advanced Science, Volume 12, Issue 31, August 21, 2025.
A label‐free organoid photoacoustic imaging (LFOPI) system is developed for precise volumetric drug screening evaluation. As a proof of concept, LFOPI's performance in chemotherapy and immunotherapy drug screening assays are further evaluated. The LFOPI offers unique non‐invasive, label‐free capabilities for tumor organoids, and contributes to the ...

Online measurement of veneer lathe checks

, 2015
The present work deals with online lathe checks measurement. It is one of the most critical defects of veneer (leading to handling difficulties, excess of glue consumption, poor veneer surface quality, etc.). It could be characterized by lathe checks depth or frequency but these indicators require tedious measurements of the veneers.

An isothermal workflow for low‐cost and PCR‐free field‐based community metabarcoding

Methods in Ecology and Evolution, Volume 16, Issue 7, Page 1413-1424, July 2025.
Abstract DNA metabarcoding has revolutionized our ability to monitor ecosystems. However, the method is still rarely used in developing countries where resources are limited and fieldwork is challenging. To overcome this limitation, we designed a comprehensive workflow allowing rapid community metabarcoding with minimum, self‐manufacturable equipment ...
