The gravitational wave is a prediction of the general theory of relativity that can be detected by measuring the relative distance between two test masses (TM) along the geodesics. The TM is fixed by the cage and vent mechanism to avoid collision with the spacecraft cavity during launch. Once the drag-free spacecraft reaches its target orbit, the TM must be released by the grabbing positioning and release mechanism (GPRM) to the cage center of the inertial sensor in a limited amount of time. The capture of the TM by means of the electrostatic suspensions is crucial for the mission. However, the GPRM inevitably generates large release errors and the low electrostatic force makes the TM capture control a difficult task. Moreover, the experimental results of the LISA Pathfinder mission have shown that the TM release velocities were well higher than the ones expected. The previous robust sliding mode controller needs to be optimized.

Long-term cattle manure application significantly influences soil phosphorus (P) cycling and associated microbial communities in agricultural systems. However, the mechanisms by which P-transforming microbial communities and their ecological networks mediate P cycling and crop productivity under sustained organic amendment remain poorly understood.

The input of fresh carbon can either enhance or suppress the mineralization rate of native soil organic carbon (SOC), a process known as the priming effect. The priming effect plays a crucial role in terrestrial carbon cycling. Although previous studies have attempted to elucidate its mechanisms and responses to nitrogen (N) addition, existing findings remain inconsistent. 

Microbial necromass plays a crucial role in soil organic carbon (SOC) formation, yet the underlying abiotic and biotic factors remain poorly understood, particularly the trophic interactions between protists and fungi/bacteria that drive soil fungal and bacterial necromass accumulation. A groundbreaking 27-year field study reveals that how soil protists differentially control fungal and bacterial necromass accumulation—a key process governing SOC storage. These findings, published in Soil Ecology Letters, redefine our understanding of soil carbon dynamics.

Termites play a key ecological role in many tropical and subtropical ecosystems. By building and maintaining their nests and mounds, they substantially affect bioturbation levels, soil properties, and nutrient distribution.
