A phase-to-intensity strategy of angular velocity measurement based on photonic orbital angular momentum [PDF]
Nanophotonics, 2021 Recently, orbital angular momentum (OAM) has been adopted to measure the shape of static objects and the translation motion of moving objects in optical remote sensing. Most of these studies rely on measuring the intensity variation of OAM beams. However,

Angular velocity integration in a fly heading circuit. [PDF]
Elife, 2017 Many animals maintain an internal representation of their heading as they move through their surroundings. Such a compass representation was recently discovered in a neural population in the Drosophila melanogaster central complex, a brain region implicated in spatial navigation.

Stance and Swing Detection Based on the Angular Velocity of Lower Limb Segments During Walking. [PDF]
Front Neurorobot, 2019 Lower limb exoskeletons require the correct support magnitude and timing to achieve user assistance. This study evaluated whether the sign of the angular velocity of lower limb segments can be used to determine the timing of the stance and the swing ...

Optimal Rotational Angular Velocity Determination Method Based on Compound Rotary Semi-Strapdown Inertial Navigation System [PDF]
Sensors, 2022 Single-axis rotation modulation (SRM) still accumulates errors in the roll axis direction, which leads to the navigation accuracy not meeting the requirements of guided missiles. Compound rotation modulation (CRM) superimposes one-dimensional rotation on

Electromagnetic radiation at extreme angular velocity
Journal of High Energy Physics, 2023 We consider a system rotating at extremely high angular velocity, so that its matter is found mostly at the light-cylinder. We posit that it can be described by quantum fields confined to the two-dimensional cylindrical surface rotating about its ...

Trunk angular velocity: A convenient, valid and responsive substitute for force plate-based measures of dynamic postural stability. [PDF]
PLoS ONEObjectiveDeficits in dynamic postural stability are associated with increased risk of lower limb injuries. Objective dynamic postural stability assessments typically require force plates, which are not commonly available in the clinic.
