AbstractThe elevation gradient has long been known to be vital in shaping the structure and function of terrestrial ecosystems, but little is known about the elevation-dependent pattern of net CO2 uptake, denoted by net ecosystem productivity (NEP). Here, by analyzing data from 203 eddy covariance sites across China, we report a negative linear elevation-dependent pattern of NEP, collectively shaped by varying hydrothermal factors, nutrient supply, and ecosystem types.

Simultaneous linewidth narrowing of a multi-wavelength laser array with an arbitrary wavelength spacing based on Rayleigh backscattering is experimentally demonstrated. Rayleigh backscattering from a single 30 m high numerical aperture fiber (HNAF) is employed to simultaneously narrow the linewidths of a DFB laser array consisting of four distributed feedback (DFB) semiconductor lasers with different wavelengths.

The China-U.S. relationship is undergoing a “thaw,” to use U.S. President Joe Biden’s term. The consecutive visits of U.S. Secretary of State Antony Blinken, Treasury Secretary Janet Yellen, Special Envoy for Climate John Kerry, and Commerce Secretary Gina Raimondo to China over the last few months are clear indicators.
