We use electrical detection, in combination with microwave transmission, to investigate both resonant and nonresonant magnon-photon coupling at room temperature. Spin pumping in a dynamically coupled magnon-photon system is found to be distinctly different from previous experiments. Characteristic coupling features such as modes anticrossing, linewidth(More)
Using electrical detection of a strongly coupled spin-photon system comprised of a microwave cavity mode and two magnetic samples, we demonstrate the long distance manipulation of spin currents. This distant control is not limited by the spin diffusion length, instead depending on the interplay between the local and global properties of the coupled system,(More)
OBJECTIVE To explore a feasible approach to increase case finding of tuberculosis (TB) through intensive referral and tracing of TB suspects and patients. METHODS A quasi-experimental study was conducted in three Chinese cities. A strategic referral and tracing system was developed for the local situation in Hunan, China. Data from a 1-year monitoring of(More)
We develop a method for universally resolving the important issue of separating spin pumping from spin rectification signals in bilayer spintronics devices. This method is based on the characteristic distinction of spin pumping and spin rectification, as revealed in their different angular and field symmetries. It applies generally for analyzing charge(More)
A systematic study of the electrodynamic coupling between the ferromagnetic resonance (FMR) and the cavity mode of a microwave cavity is presented. The nature of the FMR and cavity modes, described by their resonance position and line width, is measured and compared with a classical model based on the Landau-Lifshitz-Gilbert equation and an RLC circuit,(More)
OBJECTIVE To evaluate the utility of sputum induction in the large-scale tuberculosis control program. METHODS Prospective study on sputum induction for improving the diagnostic yield of pulmonary tuberculosis, and estimation of the direct costs for sputum induction. RESULTS Of 1,648 tuberculosis suspects with poor or absent sputum production, induced(More)
