Abstract: Disclosed are a new AXL-targeting monoclonal antibody and antibody-drug conjugate. Also disclosed is a method for preparing said antibody and antibody-drug conjugate. The AXL antibody of the present invention can bind with purified human AXL protein and multiple AXL on tumor cell surface with high effectiveness and high specificity. Said humanized antibody also has high affinity and low immunogenicity. Said AXL antibody-drug conjugate has markable performance against tumors having high AXL expression.

Abstract: The recognition system for security check and control method thereof. The recognition system for security check is integrated with a reinforcement learning algorithm and an attention region proposal network. The recognition system for security check comprises the following modules: an object feature extraction module (1); a dangerous item region segmentation module (2); a preliminary classification module (3); a preliminary classification result determination module (4); and a fine-grained recognition module (5). In the invention, optimization of a dangerous item region segmentation module and provision of a fine-grained recognition module greatly improve accuracy and efficiency of security check, shorten the duration of security check, alleviate congestion, save labor, and reduce pressure on security check personnel.
