Wetland-to-Meadow Transition Alters Soil Microbial Networks and Stability in the Sanjiangyuan Region
Published 2025-05-01Get full textWetlands and meadows are two terrestrial ecosystems that are strikingly distinct in terms of hydrological conditions and biogeochemical characteristics. Wetlands generally feature saturated soils, high accumulation of organic matter, and hypoxic environments. They support unique microbial communitie...

Studying the Double Rayleigh Backscattering Noise Effect on Fiber-Optic Radio Frequency Transfer
Published 2021-01-01Get full textWe report the effect of the double Rayleigh backscattering (DRB) noise, in which the interference of the signal light with the double Rayleigh backscattered light, on the fiber-optic radio-frequency (RF) transfer system. Here, we theoretically analyze and experimentally demonstrate that the DRB nois...

An Optical Pulse Shaping Scheme for Simultaneous Photonic Filtering and Digitizing Systems
Published 2020-01-01Get full textThe equivalent filter response in the simultaneous photonic filtering and digitizing system is determined by the temporal precision and duration time of optical pulses. To achieve narrow-bandwidth filter response at high central frequency, a pulse shaping scheme based on the time-frequency mapping a...

High-Precision Ultralong Distance Time Transfer Using Single-Fiber Bidirectional-Transmission Unidirectional Optical Amplifiers
Published 2016-01-01Get full textThis paper demonstrates a fiber-optic time transfer over a 6000 km noncalibrated fiber link using proposed single-fiber bidirectional-transmission unidirectional optical amplifiers (SFBT-UOAs). The proposed SFBT-UOA employs a 2 × 2 optical switch to enable the time-division-mul...
