Fault-Tolerant Collaborative Control of Four-Wheel-Drive Electric Vehicle for One or More In-Wheel Motors’ Faults by Han Feng, Yukun Tao, Jianbo Feng, Yule Zhang, Hongtao Xue, Tiansi Wang, Xing Xu, Peng Chen

“…In the layer of motion tracking, a vehicle model with two-degree-of-freedom is employed to predict the control reference values of the longitudinal force and additional yaw moment required; four types of sensors, such as wheel speed, acceleration, gyroscope, and steering wheel angle, are used to calculate the actual values. At the torque distribution layer, SSOD and MSCD distribution schemes are designed to cope with two operating conditions, namely sufficient and insufficient output capacity after local hub motor failure, respectively, focusing on the objective function, constraints, and control variables of the MSCD control strategy. …”

Analysis of the Integrated Signal Design for Near-Space Communication, Navigation, and TT&C Based on K/Ka Frequency Bands by Lvyang Ye, Shaojun Cao, Zhifei Gu, Deng Pan, Binhu Chen, Xuqian Wu, Kun Shen, Yangdong Yan

“…The results show that when the K/Ka signal is transmitted in the NS, the path loss changes significantly with the elevation angle. The bottom layer loss at an elevation angle of 90° is between 143.5 and 150.5 dB, and the top layer loss is between 157.5 and 164.4 dB; the maximum attenuation of the bottom layer and the top layer at an elevation angle of 0° is close to 180 dB and 187 dB, respectively. …”

Comparative efficacy of conservative interventions for adolescent idiopathic scoliosis: a systematic review and network meta-analysis of randomized controlled trials by Jun Ren, Shoujian Wang, Miaoxiu Li, Xin Zhou, Ya Wen, Zonglin Wen, Jiannan Lin, Lingjun Kong, Min Fang

“…Although brace alone (MD: 1.53, 95% CI: 1.09 to 2.14, high certainty) could be the intermediate effective intervention in preventing scoliosis progression, moderate to high certainty evidence showed that brace alone and PSSE alone probably have little or no difference in improving Cobb angle, function, mental health, self-image, angle of trunk rotation (ATR), or satisfaction of patients with AIS compared to minimal interventions. …”
