Shaoma Zhijing granule for children with tic disorders: A rapid health technology assessment

Objective:To rapidly assess the effectiveness,safety,economy,and applicability of Shaoma Zhijing granule(SZG)for the treatment of children with tic disorders(TD),and provide currently available best evidence for decision-makers of health policies.Methods:We conducted a rapid health technology assessment(RHTA)to explore the value of SZG.A systematic literature search in eight literature databases and on three clinical trial registration platforms was performed.The literature was screened according to eligibility criteria.The screening process and data extraction were conducted by two reviewers,and the quality of the literature was also assessed.The results were summarized,analyzed,and presented in tables or figures.Results:A total of five randomized controlled trials(RCTs)were included in this study,of which one was published in English(in the Journal of Child Psychology and Psychiatry)and four in Chinese journals.The overall risk of bias for the five RCTs was evaluated as“some concerns.”SZG monotherapy or in combi-nation with tiapride was better than tiapride alone in improving traditional Chinese medicine(TCM)syndromes and tic symptoms,with a daily cost of¥67.50e107.22.Adverse events were mainly related to the digestive,respiratory,and neurological systems,but all were mild.Conclusion:Overall,the current RHTA of published,peer-reviewed literature has located a small body of evidence evaluating the use of SZG for the treatment of TD in children.SZG has effects on improving TCM syndromes and tic symptoms;the daily cost is¥67.50e107.22;and all adverse events are mild.High-quality studies with long-term follow-up should be conducted,so as to provide local evidence and consistently guide and improve scientific decision-making.

A review of intelligent ore sorting technology and equipment development

Under the background of increasingly scarce ore worldwide and increasingly fierce market competition,developing the mining industry could be strongly restricted.Intelligent ore sorting equipment not only improves ore use and enhances the economic benefits of enterprises but also increases the ore grade and lessens the grinding cost and tailings production.However,long-term research on intelligent ore sorting equipment found that the factors affecting sorting efficiency mainly include ore information identification technology,equipment sorting actuator,and information processing algorithm.The high precision,strong anti-interference capability,and high speed of these factors guarantee the separation efficiency of intelligent ore sorting equipment.Color ore sorter,X-ray ore transmission sorter,dual-energy X-ray transmission ore sorter,X-ray fluorescence ore sorter,and near-infrared ore sorter have been successfully developed in accordance with the different characteristics of minerals while ensuring the accuracy of equipment sorting and improving the equipment sorting efficiency.With the continuous improvement of mine automation level,the application of online element rapid analysis technology with high speed,high precision,and strong anti-interference capability in intelligent ore sorting equipment will become an inevitable trend of equipment development in the future.Laser-induced breakdown spectroscopy,transientγneutron activation analysis,online Fourier transform infrared spectroscopy,and nuclear magnetic resonance techniques will promote the development of ore sorting equipment.In addition,the improvement and joint application of additional high-speed and high-precision operation algorithms(such as peak area,principal component analysis,artificial neural network,partial least squares,and Monte Carlo library least squares methods)are an essential part of the development of intelligent ore sorting equipment in the future.

大型运载火箭重量特性快速测量技术研究

In order to further adapt to the task requirements for rapid testing and high-density launches,the LM-5 series of rocket boosters have adopted an automated acquisition and measurement process for key parameters such as the weight and centroid of the launch vehicle.A fully automatic rapid measurement technology for the weight characteristics of the rocket,consisting of a measurement system,a control system,an execution system,and a data processing system,has been developed and incorporated.This does not just achieve the adjustment of the overall assembly attitude of the rocket body and the measurement of the center of mass,but also greatly reduces the workload in the traditional measurement operations such as for assembly erection and rail transfer.Thus improving the general convenience,while greatly improving the reliability and measurement accuracy of product installation,which further promotes the popularization of an intelligent measurement technology application.

Simulation and experimental research of digital valve control servo system based on CMAC-PID control method

Digital valve control servo system is studied in this paper. In order to solve the system problems of poor control precision and slow response time,a CMAC-PID( cerebellar model articulation controller-PID) compound control method is proposed. This compound controller consists of two components: one is a traditional PID for the feedback control to guarantee stability of the system; the other is the CMAC control algorithm to form a feed-forward control for achieving high control precision and short response time of the controlled plant. Then the CMAC-PID compound control method is used in the digital valve control servo system to improve its control performance. Through simulation and experiment,the proposed CMAC-PID compound control method is superior to the traditional PID control for enhancing stability and robustness,and thus this compound control can be used as a new control strategy for the digital valve control servo system.

Effect of Molding Material Temperature on Workpiece in FDM

Fused deposition molding is an advanced kind of rapid prototyping technology. On the accuracy of the forming process, the research on the temperature of the molding material is based on the analysis of the forming parameters. The influence of the tenlperature of the molding material on the specimen is reasonably described by the actual forming part and the finite element analysis model. The experimental results show that the temperatur（ of the molding material is less affected by the temperature of the molding material in a certain range. This will lay the theoretical foundation for the formation of the molding technology in the future
