To promote the germination of rice panicles during the regeneration season, it is necessary to ensure a stubble height of 300?450 mm when mechanically harvesting the first-season rice. However, due to variations in the depth of the paddy soil and fluctua...

A pressure sensor, located for four months in the middle of a 1275 m-long taut deep-ocean mooring in 2380 m water depth above a seamount with sub-surface top-buoys and seafloor anchor-weight, demonstrates narrow-band spectral peaks of deterministic well-...
