Intuitionistic Fuzzy TOPSIS‐Based Ranking Alternatives of Machining Performance of Ultrasonic‐Assisted Turning in Fabricated Magnesium Alloys for Sustainability

open access: yesJournal of Engineering, Volume 2026, Issue 1, 2026.
This study is aimed at optimizing the machining performance of magnesium alloys in ultrasonic‐assisted turning (UAT) by enhancing surface quality, tool life, and overall efficiency while minimizing tool wear and energy consumption. Magnesium alloys were fabricated using a bottom‐pouring stir casting technique with commercial pure magnesium (99.9 ...

Shear Wave Optical Coherence Elastography and Structural Analysis of the Postnatal Mouse Cornea through Development

open access: yesJournal of Biophotonics, Volume 18, Issue 12, December 2025.
This paper investigates the geometrical and biomechanical properties of neonatal eyes at the early stages of development. We found that the corneal thickness is uncoupled from elastic wave speed and that the content and organization of the cornea primarily influence its mechanical properties.

Sulfur‐bearing serpentine in carbonaceous chondrites

open access: yesMeteoritics &Planetary Science, Volume 60, Issue 12, Page 2864-2890, December 2025.
Abstract A correlative multi‐technique approach, including electron microscopy and X‐ray synchrotron work, has been used to obtain both structural and compositional information of a sulfur‐bearing serpentine identified in several carbonaceous chondrites (Winchcombe CM2, Aguas Zarcas CM2, Ivuna CI, and Orgueil CI), and in Ryugu samples returned by the ...

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

open access: yesAdvanced 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.

Anomaly Detection Method for Hybrid Workpieces Using Dynamic Time Warping

open access: yesAdvanced 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.
