Abstract: The present invention relates to an isolated anti-CD16A single-domain antibody, and a monospecific antibody molecule or a multispecific antibody molecule comprising the anti-CD16A single-domain antibody as a moiety. The present invention also relates to a nucleic acid encoding the anti-CD16A single-domain antibody, the monospecific antibody molecule, or the multispecific antibody molecules, a host cell comprising the nucleic acid, and a method for preparing the anti-CD16A single-domain antibody, the monospecific antibody molecule, or the multispecific antibody molecule. Furthermore, the present invention relates to use of the anti-CD16A single-domain antibody, the monospecific antibody molecule, or the multispecific antibody molecule for the treatment and/or prevention or diagnosis of acute and chronic infectious diseases (e.g., bacterial or viral infections) or a tumor.

Abstract: The present disclosure provides an application of fish swim bladder-derived heparin-like mucopolysaccharide in the preparation of angiogenesis inhibitors, belonging to the technical field of medication. In the present disclosure, the structural unit of the fish swim bladder-derived heparin-like mucopolysaccharide is ?-?GlcUA-[1?3]-GalNAc-4S. The fish swim bladder-derived heparin-like mucopolysaccharide has strong inhibition on angiogenesis. As shown from the results of examples in the present disclosure, the inhibitory rate of 400 mg/L fish swim bladder-derived heparin-like mucopolysaccharide on the growth of human umbilical vein endothelial cells can be up to 90.3%; and the inhibitory rate of 1 mg/mL fish swim bladder-derived heparin-like mucopolysaccharide on the angiogenesis of chick embryo chorioallantoic membrane is 77.15%.

Abstract: Embodiments of this disclosure provides a heartbeat information sending method and apparatus, a heartbeat information processing method and apparatus, and a node. One example method includes: determining at least one heartbeat receiving node in which at least two follower data blocks corresponding to at least two leader data blocks in a heartbeat sending node are located; and when the at least one heartbeat receiving node is a single heartbeat receiving node, sending heartbeat information of the heartbeat sending node to the single heartbeat receiving node, where the heartbeat information of the heartbeat sending node is obtained after respective heartbeat information of the at least two leader data blocks are combined.

Abstract: Various embodiments provide a storage cluster configuration change method, an apparatus, a computer system, and the like. In a storage cluster that uses a consensus replication protocol, when half of storage nodes become faulty, if it is determined that at least one storage node exists in the storage cluster after the fault, and a latest log index number of the storage node is greater than or equal to an index number of a committed log provided by the storage cluster for a client, an arbitration module sends a forced cluster configuration change instruction to a fault-free storage node. The forced cluster configuration change instruction is used to instruct the fault-free storage node to change local cluster configuration information.

Abstract: A configuration and quotation processing method and system, a configuration and quotation device, and a configuration conversion device are provided. The method includes: acquiring a sales bill of material (SBOM) configuration rule of a product; calculating a configuration bill of material (BOM) of the product according to the SBOM configuration rule, a product price, and received quotation configuration parameters; filtering the configuration BOM according to a preset output content and structure rule to generate an SBOM of the product; and converting the SBOM into a base bill of material (BBOM) according to an SBOM to BBOM (S2B) conversion rule. As such, a client-oriented SBOM can be automatically generated, thereby ensuring the accuracy of the SBOM, and improving the work efficiency.

Abstract: A Session Initiation Protocol (SIP) authentication method, sends a request message without authentication information to a server end from a client to request for access; sends back a response message, which contains authentication exchange information and DH authentication response information of the server end when the server end receives the request message; authenticates the received response message by the client and sending a request message, which contains authentication information of the client, to the server end after the authentication is passed; authenticates a user according to the received request message by the server end, and sends back a response message which contains the authentication information of the server end; authenticates the legality of the server end by the user according to the received response message, which contains the authentication information of the server end.
