A new method, called ElEx (elastic extinction), is proposed for the estimation of extinction coefficient lidar profiles using only the information provided by the elastic and polarization channels of a lidar system.The method is applicable to lidar measurements both during daytime and nighttime under well-defined aerosol mixtures.ElEx uses the part

20 million tons of well-facilitated grain storage granary (WFGSG) will be finished in the 14th Five-year Plan period.Based on the experience of compiling the technical points and regulations, this paper proposed the specific requirements of WFGSG, including excellent building performance, advanced loading and unloading processes, green technology o

Titanium and Titanium alloys are widely used as biomedical implants in oral and maxillofacial surgery, due to superior mechanical properties and biocompatibility.In specific clinical populations such as the elderly, diabetics and patients with metabolic diseases, the failure rate of medical metal implants is increased significantly, putting them at
