Abstract: An RoCE network congestion control method includes a first network device that sends a RoCE protocol packet to a second network device. The first network device receives an acknowledgment packet from the second network device that includes indication information and acknowledgment information in response to the RoCE protocol packet. The indication information indicates whether a network path between the first network device and the second network device is congested. The first network device performs congestion control based on the acknowledgment packet.

Abstract: The disclosure discloses a porcine epidemic diarrhea virus S protein and a subunit vaccine thereof as well as a method for preparing the subunit vaccine and application thereof. The vaccine contains 30˜220 ?g of a recombinant porcine epidemic diarrhea virus S protein and a pharmaceutically acceptable ISA 201 VG adjuvant. A method for preparing the subunit vaccine comprises the following steps: (1) cloning the recombinant porcine epidemic diarrhea virus S protein; (2) expressing and purifying the recombinant porcine epidemic diarrhea virus S protein; (3) preparing the recombinant porcine epidemic diarrhea virus S protein prepared in (2) into a water phase; (4) emulsifying the water phase and the ISA 201 VG adjuvant in a volume ratio of 46:54 to obtain a vaccine. The vaccine is high in safety, good in immunogenicity, stable in batches, low in production cost and strong in immunogenicity.

Abstract: A method for selectively dissolving the beta (?) phase of a titanium alloy out of the surface of the alloy, thereby leaving behind a nano-scale porous surface having enhanced bonding properties with either a biological tissue, such as bone, or an adhesive material, such as a polymer or ceramic by immersing the alloy in an ionic aqueous solution containing high levels of hydrogen peroxide and then exposing the alloy to an electrochemical voltage process resulting in the selective dissolution of the beta phase to form a nano-topographic metallic surface.
