  • Publication number: 20240398960
    Abstract: A method for preparing an antibody-drug conjugate. The antibody-drug conjugate is formed by means of site-directed conjugation on the basis of an N-glycosylation site of an Fc region of an antibody. The method comprises: (1) providing a donor containing an oxazoline oligosaccharide, an antibody containing a GlcNAc motif, and an immobilized endoglycosidase having a glycoside transfer activity; and (2) covalently linking the activated donor containing the oxazoline oligosaccharide to the antibody containing the GlcNAc motif by means of the catalytic action of the endoglycosidase; therefore, one-step conjugation is realized. The present invention also relates to an endoglycosidase fusion protein, which comprises a covalently linked endoglycosidase, a Halo tag, and/or a His tag.

  • Patent number: 12154251
    Abstract: An image processing method includes segmenting, by a cloud server and based on a zoom ratio of a high-definition image in a high-definition image library, a low-definition image of a small zoom ratio from a terminal to obtain a plurality of image blocks. For each image block, performing, by the cloud server, retrieval and matching in the high-definition image library to obtain one or more high-definition reference images, and then performing, by the cloud server, image quality improvement using an image enhancement network that is based on the high-definition reference images to obtain a plurality of high-definition image blocks. Finally, stitching, by the cloud server, the high-definition image blocks into a super-definition image with higher resolution and higher definition, and returning, by the cloud server, the super-definition image to the terminal.

  • Publication number: 20240381382
    Abstract: Aspects relate to techniques for efficient sidelink resource reservation based on the congestion on a sidelink. A wireless communication device may transmit control information indicating a number of resources reserved for an initial transmission and at least one retransmission of a packet. In some examples, the number of resources included in the control information can be either three resources or two resources based on the congestion. For example, the number of resources included in the control information can be three resources in response to a congestion value representing the congestion on the sidelink being less than a threshold. In addition, the number of resources included in the control information can be two resources in response to the congestion value being greater than or equal to the threshold.
