Abstract: A method for detecting an object in an image includes: obtaining an image to be detected; generating a plurality of feature maps based on the image to be detected by a plurality of feature extracting networks in a neural network model trained for object detection, in which the plurality of feature extracting networks are connected sequentially, and input data of a latter feature extracting network in the plurality of feature extracting networks is based on output data and input data of a previous feature extracting network; and generating an object detection result based on the plurality of feature maps by an object detecting network in the neural network model.

Abstract: Disclosed are antibodies to anti-hepatitis B surface antigen (HBsAg) (especially humanized antibodies), nucleic acid molecules encoding same, methods for preparing same, and pharmaceutical compositions containing same. The antibodies have higher affinity for HBsAg at neutral pH than at acidic pH, thereby significantly enhancing the virus clearance efficiency and prolonging the virus inhibition time. The antibodies and the pharmaceutical compositions can be used for preventing and/or treating HBV infections or diseases related to HBV infections (e.g., hepatitis B), for neutralizing the virulence of HBV in a subject (e.g., a human), for reducing the serum level of HBV DNA and/or HBsAg in the body of the subject, or for activating the humoral immune response of the subject (e.g., a chronic HBV infected or chronic hepatitis B patient) against HBV.

Abstract: A heat pump system may be selectively operated in a defrost mode or cycle. The system includes an energy recovery module that receives and conditions air in a regeneration air channel. A pre-processing module is positioned downstream of the energy recovery module. The pre-processing module receives and heats air from the energy recovery module. A regeneration air heat exchanger is positioned downstream of the pre-processing module. The regeneration air heat exchanger receives and conditions air from the pre-processing module. The pre-processing module heats the air from the energy recovery module to increase an efficiency of the regeneration air heat exchanger. During the defrost mode, a loop of regeneration air may be recirculated between the supply air channel and the regeneration air channel in order to defrost the regeneration air heat exchanger.
