| 2 | Trends in point-of-care ultrasound protocols in the emergency department and intensive care unit:a review显示文摘Together with the development of the focused assessment with sonography for trauma protocol for ultrasound in trauma patients,point-of-care ultrasound is widely used in the field of emergency and critical care medicine.Researchers have established several classic operating protocols for different diseases,such as acute respiratory failure,shock,and cardiac arrest,in the emergency department and intensive care unit.With further development in the portability and popularity of ultrasonic equipment,it is expected to be used as a new type of technology for physical examination,including inspection,palpation,percussion,auscultation,and insonation,which will improve the clinical medicine practice in the future. | Xinhui Fan Yuan Bian Guoying Wang Weikang Liu Luyao Gao Yuhui Pan Shengchuan Cao Qiuhuan Yuan Shujian Wei Feng Xu Yuguo Chen | 2023 | Emergency and Critical Care Medicine2023，3，2： | 0 |
| 3 | System dynamics in structural strength and vibration fatigue life assessment of the swing bar for high‐speed maglev train显示文摘High‐speed maglev trains are subjected to severe dynamic loads,thus posing a failure hazard.It is necessary to account for the vehicle dynamics to improve the structural strength and fatigue life assessment approach under harsh routes and super high‐speed grades.As the most critical load‐carrying part between the vehicle body and levitation frames,the swing bar was taken as an example to demonstrate the significance of vehicle dynamics to integrate classical structural strength and fatigue life with the service conditions.A multiphysics‐coupled dynamic model of an alpha improvement scheme for an electromagnetic suspension maglev train capable of 600 km/h was established to investigate the complex dynamic loads and fatigue spectra.Using this model,the structural strength and fatigue life of the wrought swing bars were investigated.Results show only a slight effect on the structural strength and fatigue life of swing bars by the super high‐speed grades.The nonaxial bending moments caused by the uncompensated relative displacement between the vehicle body and bolsters are identified as the decisive factors.The minimum safety factor of the structural strength for wrought swing bars is 1.33,while the minimum fatigue life is 34 years.Both match the design requirements but are not conservative enough.Therefore,further verification and optimization are recommended to improve the design of swing bars. | Feng Guo Feifei Hu Shengchuan Wu Feng He Jianxin Liu Xingwen Wu | 2022 | International Journal of Mechanical System Dynamics2022，2，2： | 0 |
