DOI: 10.1063/1.4989716

Abstract: The Trapped-Gyro-Landau-Fluid (TGLF) transport model is a physically realistic and comprehensive theory based on a local quasilinear transport model fitted to linear and nonlinear GYRO gyrokinetic simulations [Staebler et al., Phys. Plasmas 14, 55909 (2007)].… read more here.

DOI: 10.1080/09500340.2018.1514472

Abstract: ABSTRACT Fibre optic gyros (FOGs) are widely used in the rotation inertial navigation system (RINS). However, FOGs are sensitive to surrounding environments, and thus the drifts of FOGs would vary during the rotation of the… read more here.

DOI: 10.1364/oe.26.008645

Abstract: To improve long-term stability, we present a single-polarization resonator optic gyro based on a hollow-core photonic-crystal fiber (HCPCF), utilizing a micro-optical polarizing coupler formed by pairs of collimators and a series of polarization-dependent devices. We… read more here.
