How to improve superlubricity performance of diketone at steel interface: Effects of oxygen gas
Friction, 2022 Achievement of steady and reliable super-low friction at the steel/steel contact interface, one of the most tribological systems applied for mechanical moving parts, is of importance for prolonging machine lifetime and reducing energy consumption.

The Physics Teacher, 1998 We discuss two basic properties of angular displacements, namely, the anticommutation of finite rotations, and the commutation of infinitesimal rotations, and show how commutation is achieved as the angular displacement gets smaller and smaller.

Nonlinear Dynamic Analysis of Rotor-Bearing-Pedestal Systems With Multiple Fit Clearances
IEEE Access, 2020 Dynamic analysis of a rotor-bearing-pedestal system with multiple bearing clearances is conducted in this study. Firstly, Jones-Harris method is used to deduce the equivalent nonlinear support stiffness of angular contact high-speed ball bearing with ...

Journal of High Energy Physics, 1999 We present a class of spacetime rotations that preserve a proportion of spacetime supersymmetry. We then give the rules for superposing these rotations with various branes to construct rotating brane solutions which preserve exotic fractions of supersymmetry.

(d-2)-Dimensional Edge States of Rotation Symmetry Protected Topological States. [PDF]
Physical Review Letters, 2017 We study fourfold rotation-invariant gapped topological systems with time-reversal symmetry in two and three dimensions (d=2, 3). We show that in both cases nontrivial topology is manifested by the presence of the (d-2)-dimensional edge states, existing ...

Atraumatic shoulder instability: patient characteristics, comorbidities, and disability
JSES International, 2021 Background: Atraumatic shoulder instability of the shoulder is well described, and numerous extrinsic factors have been identified as having a negative influence on long-term shoulder function, including age, sex, smoking, and workers' compensation ...

Rotations and rotation matrices [PDF]
Acta Crystallographica Section D Biological Crystallography, 2001 In molecular replacement, a model, described as a list of orthogonal coordinates, is to be moved into a new position and orientation. The orthogonal coordinate system also has to be related to the crystallographic system, which may not be orthogonal, and crystallographic symmetry must be considered, which applies to coordinates expressed as fractions ...
