Electromagnetic Gyroscopic Motion [PDF]
Journal of Applied Mathematics, 2012 A problem of the gyroscopic motions around a fixed point, under the action of a gyrostatic moment vector, in presence of electromagnetic field and Newtonian one, is considered. The small parameter technique is used to investigate the periodic solutions for the derived equations of such motion problem. A geometric interpretation of motion will be given

Microresonator Brillouin Gyroscope [PDF]
Nonlinear Optics, 2015 Using counter-propagating Brillouin lasers in a high-Q chip-based resonator, rotation measurement with a sensitivity of 15 degree/hour/ Hz is demonstrated. This is close to navigation grade performance and surpasses prior micro-optical systems by 40X.

The Frenet Serret Description of Gyroscopic Precession [PDF]
, 1993 The phenomenon of gyroscopic precession is studied within the framework of Frenet-Serret formalism adapted to quasi-Killing trajectories. Its relation to the congruence vorticity is highlighted with particular reference to the irrotational congruence ...

Eigenmode operation of piezoelectric resonant gyroscopes
Microsystems & Nanoengineering, 2020 The theory of eigenmode operation of Coriolis vibratory gyroscopes and its implementation on a thin-film piezoelectric gyroscope is presented. It is shown analytically that the modal alignment of resonant gyroscopes can be achieved by applying a rotation

Adeno‐associated virus serotype 2 capsid variants for improved liver‐directed gene therapy
Hepatology, EarlyView., 2022 Abstract Background and Aims Current liver‐directed gene therapies look for adeno‐associated virus (AAV) vectors with improved efficacy. With this background, capsid engineering is explored. Whereas shuffled capsid library screenings have resulted in potent liver targeting variants with one first vector in human clinical trials, modifying natural ...
