A New Vestibular Stimulation Mode for Motion Sickness With Emphatic Analysis of Pica

open access: yesFrontiers in Behavioral Neuroscience, 2022
Motion sickness (MS) was frequently introduced for rodents in research work through passive motion that disturbed vestibular signals in the presence of visual and aleatory, proprioceptive inputs.

Rotation invariant ultradistributions [PDF]

open access: yes, 2017
We prove that an ultradistribution is rotation invariant if and only if it coincides with its spherical mean. For it, we study the problem of spherical representations of ultradistributions on $\mathbb{R}^{n}$. Our results apply to both the quasianalytic

Rotational aerophones

open access: yesThe Journal of the Acoustical Society of America, 2002
Free rotational aerophones such as the bullroarer, which consists of a wooden slat whirled around on the end of a string, and which emits a loud pulsating roar, have been used in many ancient and traditional societies for ceremonial purposes. This article presents an experimental and theoretical investigation of this instrument.

Mechanical Faraday effect for orbital angular momentum-carrying beams [PDF]

open access: yes, 2014
When linearly polarised light is transmitted through a spinning window, the plane of polarisation is rotated. This rotation arises through a phase change that is applied to the circularly polarised states corresponding to the spin angular momentum (SAM).

Health Monitoring on the Spacecraft Bearings in High-Speed Rotating Systems by Using the Clustering Fusion of Normal Acoustic Parameters

open access: yesApplied Sciences, 2019
The rolling bearings in moment wheel assemblies (MWAs) or control moment gyros (CMGs) are not only the core components in spacecrafts but also prone to failure.
