| 1 | 12-Point Leveling Systems for Mobile Platforms and Emergency Plans显示文摘With high stability,strong bearing capacity and other characteristics,multi-point leveling systems have been widely used in various industries.The mobile platform here uses a 12-point leveling system,which is mainly composed of the mechanical transmission system of the supporting arm,a hydraulic drive system and an electrical control system.The leveling is realized through the proportional lifting of the arms in four quadrants.In order to ensure the smooth conduct of launch missions,emergency plans were made for the leveling system incase of failure of a single arm. | LIU Yu ZHANG Shuai HE Jianhua ZHU Miaoxin ZENG Yi ZHOU Li | 2023 | Aerospace China2023，24，3： | 0 |
| 2 | Worldwide 1-month case fatality of ischaemic stroke and the temporal trend显示文摘background The 1-month case fatality of ischaemic stroke is an essential epidemiological metric.Whereas the case fatality after ischaemic stroke and the temporal trend is uncertain.We aimed to estimate the 1-month case fatality of ischaemic stroke and its temporal trend,as well as its regional variation.Methods We searched PubMed and Embase to identify the studies for 1-month case fatality of ischaemic stroke.The population-based studies were included.Two investigators extracted the data and assessed the quality independently.One-month case fatality of ischaemic stroke was estimated using a random effects model.The temporal trend was evaluated using a mixed-effect meta-regression model.results A total of 59 articles with 77 time periods were included.The worldwide 1-month case fatality of ischaemic stroke was 13.5%(95%CI 12.3%to 14.7%).The case fatality was 10.8%(95%CI 8.3%to 13.5%)in Asia,14.2%(95%CI 12.6%to 15.9%)in Europe,14.0%(95%CI 11.2%to 17.1%)in South America and Caribbean,14.0%(95%CI 9.5%to 19.1%)in North America and 12.5%(95%CI 11.1%to 13.9%)in Australia and New Zealand.Overall,there was a non-significant decrease of 0.1%per year in case fatality.It decreased significantly in Europe(−0.2%annually,95%CI−0.4%to−0.01%)and North America(−0.2%annually,95%CI−0.4%to−0.04%),increased significantly in Australia and New Zealand(0.2%annually,95%CI 0.1%to 0.4%),while no evidence of change in other regions.Conclusion The 1-month case fatality of ischaemic stroke and its temporal trend were divergent across regions.Further studies are needed to address the reason of the regional difference,which will be helpful to guide the effort of reducing stroke burden. | Runhua Zhang Yu Wang Jiming Fang Miaoxin Yu Yongjun Wang Gaifen Liu | 2020 | Stroke & Vascular Neurology2020，5，4： | 0 |
