Summary: This paper investigates the reduction of electromagnetic noise in five-phase squirrel cage induction motors. By utilizing slot-number phase diagram and electromagnetic force-vibration-acoustic analytical model, the influence of pole-slot schemes on magnetic noise is analyzed. The feasibility of electromagnetic noise prediction is verified through finite element simulation and experiments. The study provides a pole-slot numbers matching rule for noise reduction design of five-phase motors in different power ranges.

Summary: The study shows that the CRB for a target's relaxation frequency response is independent of the amplitudes of other relaxations but is affected by the proximity of relaxation frequencies. Additionally, the RMSE per relaxation frequency changes with the number of relaxation frequencies present in the target's response.

Summary: In this study, Bertotti loss separation was used for the first time to accurately calculate the changes of complex permeability in Mu-metal shields due to hysteresis loss at different frequencies and magnetic field intensities, with consideration of the induced eddy current effect on magnetic field intensity. The high agreement between calculation and experimental results proved the accuracy of the proposed method, which can be applied in the design and optimization of low-noise magnetic shields to improve the sensitivity of atomic devices.

Summary: The study proposes a magnetic induction through-the-earth positioning scheme that achieves high-precision and long-distance three-dimensional underground positioning. By utilizing the directional characteristics of the magnetic field vector distributed by the transmitter coil, two positioning methods are designed to determine the horizontal and vertical positions of the transmitter; meanwhile, a noise reduction method using frequency-point amplitude acquisition is employed to reduce the impact of noise on positioning accuracy.

Summary: This article investigates the helical motion coupling effect of the two-degree-of-freedom split-stator induction machine (2DoFSSIM) and analyzes the influence of stator-slot and pole-pair combinations on three motion characteristics. The resistant torque and force production mechanism based on the proposed motion coupling model are revealed. It is concluded that the output torque, force, and helical motion coupling effect are determined by the magnetic loading and pole-pair number of the motion parts. However, there is a tradeoff in choosing the pole-pair number to balance output performances and helical motion coupling effect.

Summary: As spin-based quantum processors grow in size and complexity, maintaining high fidelities and minimizing crosstalk are crucial for successful quantum algorithms and error-correction protocols. This study makes significant progress in understanding and overcoming the detrimental effects of microwave qubit driving on qubit frequency shifts. Operating the device at 200 mK effectively suppresses adverse heating effects without compromising qubit coherence or fidelity benchmarks. Furthermore, systematic non-Markovian crosstalk is greatly reduced.

Summary: This paper investigates wave propagation and network dynamics of an improved Hindmarsh-Rose neuron model with magnetic induction. The dynamical properties of the model are analyzed using eigenvalues, Lyapunov exponents, and bifurcation plots, and a comparison is made between exponential and quadratic flux models. In network dynamics, external disturbances such as noise and flux excitation are considered, and it is found that low noise variance effectively suppresses spiral waves in wave propagation phenomena.

Summary: In this article, a general analytical model is proposed to evaluate the influence of armature reaction force on the linear Hall sensor signals at the slot openings of a double-layer fractional-slot concentrated-winding surface-mounted permanent magnet synchronous machine. Based on the analysis using the proposed model, it is demonstrated that the armature reaction force is almost zero at certain specific positions in FSCW-SPMSM, providing a reference for the placement of linear Hall sensors and theoretically improving the accuracy of position calculation.

Summary: The Proper Orthogonal Decomposition (POD) method is commonly used in structural dynamics to extract natural frequencies and damping ratios from experimental vibrational responses. While natural system mode shapes cannot be directly extracted from POD results, good agreement was found between POD-based results and those obtained from traditional methods. In noisy conditions, the accuracy of modal characteristics corresponding to primary natural modes is preserved.

Summary: Currently, additive manufacturing of metallic materials using expensive tools with limited control and modification options is a common practice. To address this issue and make metal parts printing more accessible and suitable for academic research, a mixture of thermoplastic polymer and metal powder is proposed. By utilizing a granular feedstock in the form of pellets and the Fused Granular Fabrication 3D printing technology, a cost-effective solution is implemented by modifying a mid-range printer and adding a compact granulates extruder.
