Rotation and pseudo-rotation [PDF]

open access: yesGeneral Relativity and Gravitation, 2005
Eigenvectors of stress-energy tensor (the source in Einstein's equations) form privileged bases in description of the corresponding space-times. When one or more of these vector fields are rotating (the property well determined in differential geometry), one says that the space-time executes this rotation.

Rotating rotated branes [PDF]

open access: yesJournal 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.

Atraumatic shoulder instability: patient characteristics, comorbidities, and disability

open access: yesJSES 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]

open access: yesActa 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 ...

Rotation and differential rotation of active Kepler stars [PDF]

open access: yes, 2013
We present rotation periods for thousands of active stars in the Kepler field derived from Q3 data. In most cases a second period close to the rotation period was detected, which we interpreted as surface differential rotation (DR).

Modeling and Experimental Study on the Micro-Vibration Transmission of a Control Moment Gyro

open access: yesIEEE Access, 2019
A control moment gyro (CMG) is the main source of vibration disturbance in the spacecraft. This paper presents a vibration mathematical model with 18 degrees of freedom by Lagrange energy method, for solving the problem that the transmission mechanism ...
