DOI: 10.1088/1361-665x/ac4db5
Abstract: The traveling waves of linear traveling wave type piezoelectric motors are not easy to stabilize due to its finite boundary structure. The traditional two-mode excitation method is a method which can excite two modes to… read more here.

DOI: 10.1103/physrevd.105.064046
Abstract: Gravitational-wave observations of black hole ringdowns are commonly used to characterize binary merger remnants and to test general relativity. These analyses assume linear black hole perturbation theory, in particular that the ringdown can be described… read more here.
