Objective: Whether moxibustion therapy is effective for patients with lumbar disc herniation(LDH) is still unclear, but previous studies neglected the dose of moxibustion and usually adopted standardized 15-minute dose in the treatment of *** of moxibustion plays an important role in obtaining good ***, we report the protocol of a randomized controlled trial to confirm the efficacy of moxibustion for LDH and to clarify the relationship between the dose and efficacy of moxibustion for ***: Forty participants with LDH were randomized into four *** small moxibustion dose group(SM), moderate moxibustion dose group(MM) and large moxibustion dose group(LM) respectively received 15-minute, 30-minute, and 60-minute treatment of suspended moxibustion on Guanyuan(CV4).The acupuncture group(AC) received acupuncture treatment as the control *** and acupuncture were performed a total of five times(once per week), a total of 10 treatments in a 2-week treatment *** was evaluated by VAS pain intensity and Roland Morris Questionnaire(RMQ).Results: VAS and RMQ scores were improved in the four groups during the *** reduction in pain intensity(P<0.01) and RMQ(P<0.01) was shown in the LM *** treatment, the group that received large moxibustion dosereported less pain intensity compared to the acupuncture group or the groups that received 15-minute and 30-minute treatments of moxibustion, and the differences were statistically significant(P<0.05).Conclusion: The large moxibustion dose treatment may be more effective in the treatment of *** time of treatment was between 15 and 60 min, and efficacy of moxibustion on CV4 gradually improved with increasing of treatment time.

Perovskite solar cells(PSCs)with a positive-intrinsicnegative(p–i–n,commonly referred to as“inverted”)structure are becoming commercially attractive due to their superior power conversion efficiency(PCE)and better operational stability as compared to the“normal”structure device.^([1–5])Nonetheless,further improvements in the device performance of inverted PSCs are hampered by interface losses,particularly where the buried interfaces are responsible for perovskite crystallization and chargecarrier extraction.^([6–9])

Accurately picking P-and S-wave arrivals of microseismic(MS)signals in real-time directly influences the early warning of rock mass failure.A common contradiction between accuracy and computation exists in the current arrival picking ***,a real-time arrival picking method of MS signals is constructed based on a convolutional-recurrent neural network(CRNN).This method fully utilizes the advantages of convolutional layers and gated recurrent units(GRU)in extracting short-and long-term features,in order to create a precise and lightweight arrival picking ***,the synthetic signals with field noises are used to evaluate the hyperparameters of the CRNN model and obtain an optimal CRNN *** actual operation on various devices indicates that compared with the U-Net method,the CRNN method achieves faster arrival picking with less performance *** application of large underground caverns in the Yebatan hydropower station(YBT)project shows that compared with the short-term average/long-term average(STA/LTA),Akaike information criterion(AIC)and U-Net methods,the CRNN method has the highest accuracy within four sampling points,which is 87.44%for P-wave and 91.29%for S-wave,*** sum of mean absolute errors(MAESUM)of the CRNN method is 4.22 sampling points,which is lower than that of the other *** the four methods,the MS sources location calculated based on the CRNN method shows the best consistency with the actual failure,which occurs at the junction of the shaft and the second ***,the proposed method can pick up P-and S-arrival accurately and rapidly,providing a reference for rock failure analysis and evaluation in engineering applications.

Space/air communications have been envisioned as an essential part of the next-generation mobile communication networks for providing highquality global connectivity. However, the inherent broadcasting nature of wireless propagation environment and the broad coverage pose severe threats to the protection of private data. Emerging covert communications provides a promising solution to achieve robust communication security. Aiming at facilitating the practical implementation of covert communications in space/air networks, we present a tutorial overview of its potentials, scenarios, and key technologies. Specifically, first, the commonly used covertness constraint model, covert performance metrics, and potential application scenarios are briefly introduced. Then, several efficient methods that introduce uncertainty into the covert system are thoroughly summarized, followed by several critical enabling technologies, including joint resource allocation and deployment/trajectory design, multi-antenna and beamforming techniques, reconfigurable intelligent surface(RIS), and artificial intelligence algorithms. Finally, we highlight some open issues for future investigation.
