Abstract: The present application provides anti-CD137 constructs that bind to CD137 (e.g., anti-CD137 monoclonal antibodies and multispecific antibodies), nucleic acid molecules encoding an amino acid sequence of the anti-CD137 constructs, vectors comprising the nucleic acid molecules, host cells containing the vectors, methods of preparing the anti-CD137 constructs, pharmaceutical compositions containing the anti-CD137 constructs, and methods of using the anti-CD137 constructs or compositions.

Abstract: The present disclosure discloses a point cloud-based map calibration method and system, a robot and a cloud platform. The method is applied to a cloud platform communicatively connected to a designated robot, and includes: obtaining environmental acquisition information from the designated robot; performing three-dimensional point cloud reconstruction on the environmental acquisition information, performing obstacle recognition on a three-dimensional point cloud reconstruction result, and obtaining an obstacle recognition result including obstacle information and confidence information corresponding to the obstacle information; and when it is determined that the confidence information satisfies a first preset index, sending map calibration information corresponding to the obstacle information to the designated robot, so that the designated robot calibrates map information according to the map calibration information.

Abstract: The present invention is related a square packed tower for collection of flue gas CO2. The square packed tower comprises an initial absorbent distributor on the lower end of the flue gas outlet, a vertical plate packer on the lower end of the initial absorbent distributor and a radial diversion gas distributor at the bottom of the square packed tower for delivery of carbon dioxide contained in the flue gas. The radial diversion gas distributor comprises a gas inlet pipe, a butterfly base plate, a butterfly seal plate and numerous radial deflectors. The butterfly base plate is connected with outlet of the gas inlet pipe. The radial deflectors are in radial arrangement between the butterfly base plate and butterfly seal plate along the outlet of gas inlet pipe.

The butterfly base plate is connected with outlet of the gas inlet pipe. The radial deflectors are in radial arrangement between the butterfly base plate and butterfly seal plate along the outlet of gas inlet pipe. Such square packed tower has solved such problems as low mass transfer efficiency, uneven distribution of gas phase inside the tower and high investment.
