摘要: An information interaction system and method for heterogeneous detection and recognition devices for a low-altitude unmanned aerial vehicle (UAV) are provided, where each edge data unit is connected to a uniquely corresponding low-altitude UAV detection and sensing device and an access and distribution unit. The access and distribution unit is connected to a storage service unit and at least one scheduling and calculation unit. Each scheduling and calculation unit is connected to a comprehensive calculation and display unit. The comprehensive calculation and display unit is connected to the storage service unit. The storage service unit sends historical data to the comprehensive calculation and display unit after being authorized. The method is applied to the information interaction system for heterogeneous detection and recognition devices for a low-altitude UAV. A problem of data collaborative application of different low-altitude UAV detection devices is resolved.

摘要: The present invention discloses a ω-transaminase mutant obtained through DNA synthetic shuffling combined mutation. The ω-transaminase mutant is obtained through point mutation of a wild type ω-transaminase from Aspergillus terrus. The amino acid sequence of the wild type ω-transaminase is shown in SEQ ID NO: 1. The mutation site of the ω-transaminase mutant is any one of: (1) F115L-H210N-M150C-M280C; (2) F115L-H210N; (3) F115L-H210N-E253A-I295V; (4) I77L-F115L-E133A-H210N-N245D; (5) I77L-Q97E-F115L-L118T-E253A-G292D; (6) I77L-E133A-N245D-G292D; and (7) H210N-N245D-E253A-G292D. According to the present invention, forward mutations obtained in the previous stage are randomly combined through a DNA synthetic shuffling combined mutation method. It is verified through experiments that this method can effectively improve the probability of forward mutation and increase experimental efficiency and feasibility, and is capable of obtaining mutant enzymes with thermodynamic stability remarkably superior to that of wild enzymes via screening.

摘要: Disclosed is a method of preparing a carbon quantum dot from soybean dregs by hydrothermal synthesis, including: mixing the soybean dregs with water, and subjecting the reaction mixture under heating at 100-500° C. in an autoclave for reaction; cooling the reaction mixture when the reaction is completed, and removing insoluble substances from the reaction mixture; and dialyzing the reaction mixture, and lyophilizing the dialyzed product to produce the carbon quantum dot. The invention further provides the carbon quantum dot prepared by the above method and a use thereof in the detection of Fe3+ and Hg2+ in water, where the lowest detection limit can reach 30 nmol/L and the detection range is 0.1-50 μmol/L.
