Abstract: A method includes obtaining historical network performance data of each of data transmission objects, calculating, based on the historical network performance data, group network performance data of each of object groups, performing weighted calculation on the group network performance data of the object groups to obtain comprehensive network performance data of the data transmission objects, inputting the comprehensive network performance data and the group network performance data into a trained RL model to obtain a data transmission quality index of each object group, for each object group, determining a data transmission parameter of the object group based on the data transmission quality index and the group network performance data of the object group, and determining, in response to receiving a data transmission request transmitted by a target data transmission object, a target data transmission parameter based on a target object group to which the target data transmission object belongs.

Abstract: The present application provides a multispecific antibody and preparation method and use thereof. The multispecific antibody comprises: a) a Fab fragment specifically binding to a first antigen, wherein the Fab fragment consists of a light chain and CH1 and a variable region of a heavy chain; b) a first peptide linker with the N-terminal end fused to the heavy chain; c) a second peptide linker with the N-terminal end fused to the light chain, wherein only one disulfide bond can be formed between the first and the second peptide linkers, and each of the first and the second peptide linkers is independently selected from the group consisting of a peptide linker comprising any of the sequences as set forth in SEQ ID NO.1-2, wherein X represents any amino acid other than Cys, or is absent.

The antibody can be readily produced by recombinant expression and can simultaneously target two different antigens or different epitopes of the same antigen, or multiple epitopes of more different antigens.

Abstract: A data request processing method, performed by a front-end server, includes receiving, through a first communication connection, a data request transmitted by a client; obtaining, based on the data request, an address of a back-end server to be scheduled, and creating a second communication connection to the back-end server based on the address; and migrating the data request to the back-end server through the second communication connection to cause the back-end server to create an analog communication connection to the client and transmit to the client, through the analog communication connection, a first data packet for responding to the data request.

Abstract: A sound box assembly for a display apparatus, includes: a housing defining a chamber therein, and a connecting part connected to the housing, and being configured to be connected with the display apparatus; and a loudspeaker arranged in the chamber of the housing, a sound-image center being disposed at a center position of the display apparatus when the loudspeaker playing sound. The loudspeaker includes a squawker arranged at a middle portion of the housing, a woofer and a tweeter. One of the woofer and the tweeter is arranged above the squawker and the other one of the woofer and the tweeter is arranged below the squawker.
