Abstract Modulation of scattering in random lasers (RLs) by magnetic fields has attracted much attention due to its rich physical insights.We fabricate magnetic gain polymer optical fiber to generate RLs.From macroscopic experimental phenomena, with the increase of the magnetic field strength, the magnetic transverse photocurrent exists in disorder

Increasing plant density seems to improve the productivity of maize crops, and the understanding of how the metabolism of non-structural carbohydrates is affected in plants under high crop density is critical.Thus, with the objective of further clarifying this issue, maize plants were subjected to densities from 30,000 to 90,000 plants ha−1,

While performing underwater observation and detection, the underwater acoustic glider needs to finish the current profile glide Timing Chains to float to the surface for information exchange and thus fails to realize real-time data information return.In this paper, a detection and communication system for underwater acoustic gliders was proposed.Th
