LifeMet: Report on the 2024–2025 meteorite recovery expedition in Dronning Maud Land, Antarctica for the study of microbe–meteorite interactions

Meteoritics &Planetary Science, EarlyView.
Abstract Since the discovery of nine meteorites near the Yamato mountains in 1969, Antarctica has been recognized as a superb location for meteorite recovery. While Antarctic recovery expeditions prioritize meteorite preservation for mineralogical and planetary studies, meteorites are not typically collected for biological applications.

An analytical fast field solver for surface permanent magnet co‐axial magnetic gears

IET Electric Power Applications
A mathematical model of co‐axial magnetic gears is given for the prediction of magnetic field distribution and the magnetic forces. The modelling approach is based on the separation of variables method (SVM), Sturm–Liouville problem, and spectral ...

Environmental DNA as a Detection and Quantitative Tool for Brown Bullhead Catfish (Ameiurus nebulosus): A Comparison With Conventional Netting

Environmental DNA, Volume 8, Issue 4, July‐August 2026.
Multiple environmental DNA (eDNA) methods were compared with each other and with fyke netting for detecting invasive brown bullhead catfish. eDNA sampling combined with catfish‐specific metabarcoding provides sensitive detection and effectively complements traditional netting for biosecurity.

A modified partitioned‐stator flux‐switching permanent magnet machine for enhancing torque‐density in electric vehicle powertrains

IET Electric Power Applications
This study proposes a modified partitioned‐stator flux‐switching permanent magnet (PS‐FSPM) machine and reduces the permanent magnet usage in conventional PS‐FSPM machines. To achieve this goal, the stators of the conventional PS‐FSPM with outer‐armature/

Time Distributed Classification of Alzheimer's Disease on MRI Scans

NMR in Biomedicine, Volume 39, Issue 7, July 2026.
Longitudinal MRI‐derived cortical thickness slopes improved AD/CN discrimination. A time‐distributed 3D ResNet‐101 + LSTM further captured spatiotemporal progression, reaching 96.7% accuracy and also improving MCI‐related classification. ABSTRACT The diagnosis of Alzheimer's disease (AD) has progressively depended on sophisticated neuroimaging methods ...

Optical Pulling Force on Gold Mie Particles via Germanium and Aluminum‐Based Structures

Advanced Photonics Research, Volume 7, Issue 6, June 2026.
This work demonstrates a novel approach to generate optical pulling force on gold Mie objects of two different shapes and studies the effects for different object sizes, incident angles, and the aluminum tetrahedra separation. Using rectangular germanium blocks combined with aluminum tetrahedra, optical pulling force (OPF) is achieved over a broad ...

A Reduction Method of Cogging Torque for Magnetic Gears

, 2023
Nowadays, magnetic gears (MGs) have become an alternative choice for mechanical gears because of their low maintenance, improved durability, indirect contact between inner and outer rotors, no lubrication, and high efficiency.
