Abstract: A method for transmitting video over a network is disclosed. The method may be implemented by a processor and a non-transitory computer-readable storage medium storing instructions. The method may comprise: receiving, from a video data source, video data; generating a set of images from the video data based on a conversion rule that corresponds to a predetermined playback video quality; and transmitting, over a network to a client device, the set of images for rendering and displaying on a browser installed on the client device.

Abstract: The present invention belongs to the field of drug crystals, relates to crystals of thiadiazole derivative DPP-IV inhibitors, and in particular relates to A and B type crystals of the compound as shown in formula 7. The crystals of the present invention have excellent stability. For example, under high temperature, high humidity or light test conditions, the material contents associated with the crystal of the compound of formula 7 do not change significantly. In addition, the crystal of the present invention also has a very good powder flowability and satisfies the requirements of drug preparation and production.

Abstract: The present invention relates to porcine reproductive and respiratory syndrome virus (PRRSV) vaccines in a field of veterinary biological products, and more particularly to a PRRSV SX-105 strain having a deposit number of CGMCC No. 9906, and a use thereof in preparing PRRSV live vaccines. PRRSV SX-1 original strains are strongly pathogenic to swine. A PRRSV SX-105 attenuated strain shows safety and good immunogenicity on the swine. The PRRSV live vaccines, prepared from the PRRSV SX-105 strain, are safe and reliable, and able to generate strong immunity after immunization. The PRRSV live vaccines significantly decrease morbidity and mortality in inoculated swine groups, and have immunization effects reaching and slightly better than conventional commercial vaccines on the market, showing advantages to compete with the same kind of products around the world. The PRRSV live vaccines are capable of effectively preventing PRRS epidemic and transmission, and has broad application prospects.
