Summary: Guided-wave-based structural health monitoring (SHM) technology is crucial for real-time inspection of high-temperature structures. The fundamental shear horizontal (SH0) wave is considered ideal for SHM systems due to its non-dispersive properties. However, the availability of SH0 wave transducers for high-temperature SHM is limited by material constraints.

Summary: In this study, a real-time capacitive sensing scheme based on electromechanical amplitude modulation is developed to detect the scanning angle and phase of a uniaxial electrostatic comb-drive micromirror for close loop control. Experimental results show that using a carrier signal with 2.5 Vpp and 1 MHz, the measurement accuracy of the scanning angle of the micromirror reaches 0.15 degrees and the time delay can be controlled within 0.47 microseconds. The proposed capacitive sensing scheme can effectively measure the angular position and phase of electrostatic comb-drive MEMS mirrors simultaneously without the need of adding any external components.

Summary: This paper proposes a PESSD device for vehicle monitoring, which combines PEH and EMH as self-powered and self-sensing modules for wireless transmission of self-sensing signals. The influence of the rectangular magnet in PEH, the coil, and the cylindrical magnet in EMH on the output performance of the prototype is studied. Under the optimal parameter conditions of prototype assembly, the maximum output voltage of PEH is 60.62 Vpp, and the maximum output voltage of EMH is 3.81 Vpp. The ability of simultaneous self-power supply and self-sensing was verified by installing eight prototype arrays into the deceleration belt and testing on the actual road.

Summary: This study investigated the development of Prochloraz resistance in Fusarium fujikuroi and analyzed the fitness of different resistant strains. The majority of the F. fujikuroi strains collected from Heilongjiang Province showed resistance to Prochloraz, with a resistance frequency of 92.1%. The resistant strains demonstrated higher disease severity and there was no cross-resistance between Prochloraz and other tested fungicides. These results indicate that Prochloraz resistance in F. fujikuroi is severe and could potentially lead to yield loss.

Summary: This study investigates a distributed six-degree-of-freedom (6-DOF) cooperative control for multiple spacecraft formation considering parametric uncertainties, external disturbances, and time-varying communication delays. Unit dual quaternions are used to describe the kinematics and dynamics models of the 6-DOF relative motion of the spacecraft. A distributed coordinated controller based on dual quaternions with time-varying communication delays is proposed. An adaptive coordinated control law is developed to compensate for parametric uncertainties and external disturbances. Numerical simulations show the effectiveness of the proposed method in cooperative control of attitude and orbit for the multi-spacecraft formation.
