Magnetorotational Instability in Liquid Metal Couette Flow
Despite the importance of the magnetorotational instability (MRI) as a fundamental mechanism for angular momentum transport in magnetized accretion disks, it has yet to be demonstrated in the laboratory.

A V‐Shaped In‐Pipe Robot to Travel Through Complex Winding Pathways in Three Dimensions
ABSTRACT This paper presents a V‐shaped gas pipeline inspection robot which achieves high roll rotation performance, out‐of‐plane double elbow travel performance, and inverted siphon adaptability at high speed without requiring complicated manual operation. The principle for traveling through the out‐of‐plane double elbow was theoretically demonstrated

Performance of Magnetic-Superconductor Non-Contact Harmonic Drive for Cryogenic Space Applications [PDF]
Harmonic drives are profusely used in aerospace mainly because of their compactness and large reduction ratio. However, their use in cryogenic environments is still a challenge. Lubrication and fatigue are non-trivial issues under these conditions.
