Summary: This article presents a bandwidth-enhanced magnetoelectric (BWE-ME) antenna made of a Mo/AlN/FeGa sandwich stack. By combining high-overtone bulk acoustic resonators (HBARs) and film bulk acoustic resonators (FBARs) in parallel, the antenna achieves a broader bandwidth. Simulation results show that the magnetic flux density bandwidth generated by the multi-resonant mode interaction is 18 MHz, which matches the measured results.

Summary: Magnetoelectric (ME) antennas utilize the direct or converse ME effects at acoustic resonance to receive or transmit electromagnetic (EM) signals, making ultra-compact antennas feasible. This study presents a miniaturized ME antenna working at very low frequency (VLF) band, achieved by bonding a piezoelectric wafer and magnetostrictive foils together. The near-field coupling between the ME antenna and magnetic rod coil has been measured to verify the reciprocity. The proposed entire circuit simulation models agree well with the experimental results, explaining the maximum power gap and frequency offset phenomenon. Additionally, both practical and simulation results confirm that near-field coupling depends on mutual inductance rather than EM radiation. The introduction of L-section impedance matching networks improves the original power transmission coefficient. The ME antenna is lightweight, wide-band, and easy to match compared with a conventional coil.

The effect of heat treatment on the stress-strain properties and microstructure of reinforcing bars is experimentally investigated, and a procedure for heat-treating standard reinforcing bars is established. By combining the experimental data with an analytical model for HRWs, the behavior of the proposed HRW, including energy dissipation and re-centering capability, is studied.

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.
