Composite body armor made of brittle ceramic and tough laminate can protect human body from penetration while reducing weight.However, there is a lack of a simple and comprehensive method for assessing ballistic impact response and blunt injury.In this study, the three-dimensional Digital Image Correlation technique was used to investigate the back
Exits are essential to the efficiency of building evacuation due to its irreplaceable function, and the layout of multiple exits has always been the key concern for architectural design.To accurately evaluate the evacuation efficiency of different multiexit layouts and optimize the design rules, a dynamic exit decision model integrating here an exi
Abstract Background Amyotrophic lateral sclerosis is a fatal neuromuscular disorder characterized by progressive death of the upper and lower motor neurons in the central nervous system.Patients with this disease die mostly as a result of respiratory failure; however, owing to prolonged survival through assisted ventilation, cardiovascular causes a
In recent years, more and more studies have shown that early pathogenic bacterial infection in invertebrates can enhance immunity and significantly reduce mortality when reinfected with the same pathogen.There are mechanisms to explain this phenomenon, but they are relatively few.In addition, dose-dependent primary infection is also associated with
