Abstract: Antibodies (especially humanized antibodies) against the hepatitis B surface antigen (HBsAg), a nucleic acid molecule encoding same, a method for preparing same, and a pharmaceutical composition containing same. The anti-HBsAg antibodies have a higher binding affinity to HBsAg at a neutral pH than at an acidic pH, thereby significantly enhancing virus clearance efficiency and prolonging virus inhibition time. The antibodies and pharmaceutical composition may be used to prevent and/or treat HBV infections or diseases related to HBV infection (such as hepatitis B) for use in neutralizing the virulence of HBV in the body of a subject (such as a human) to reduce a serum level of HBV DNA and/or HBsAg in the body of the subject, or to activate a humoral immune response of a subject (such as a person infected with chronic HBV or a patient who has chronic hepatitis B) against HBV.

Abstract: The invention discloses a lithium metal negative electrode protection method improving lithium utilization efficiency, and relates to the field of lithium batteries. In a lithium battery, lithium metal is deposited on a current collector as a battery negative electrode, and a high molecular polymer is added as an additive to an ester electrolyte. In the present application, the high molecular polymer is prepared by a polymerization reaction of monomer A being acrylonitrile or derivatives thereof, monomer B being perfluoroalkyl ethyl methacrylate or derivatives thereof, and monomer C being alkyl alcohol diacrylate or derivatives thereof. Due to the negative charge on the surface of lithium metal, the —CN and —CF3 in the polymer are strong electron-withdrawing groups, which promote the preferential adsorption of electrolyte additives on the surface of lithium metal and reduce the contact of other components in the electrolyte with lithium metal.

Abstract: A new method for reconstructing a full spectrum from under-sampled magnetic resonance spectrum data by using a deep learning network. First, the exponential function is used to generate a time-domain signal of the magnetic resonance spectrum, and a zero-filling time-domain signal is obtained after the under-sampled operation is completed in the time domain. The zero-filling time-domain signal and the full spectrum corresponding to the full sampling are combined to form a training data set. Then, a data verification convolutional neural network model is established for magnetic resonance spectrum reconstruction, where the training data set is used to train neural network parameters to form a trained neural network. Finally, the under-sampled magnetic resonance time-domain signal is input to the trained data verification convolutional neural network, and the full magnetic resonance spectrum is reconstructed.
