Abstract: A cloud infrastructure performs governance and security control for datacenters on a cloud platform. The system specifies one or more session policies for the plurality of datacenters. A session policy associated with a datacenter specifies a set of access conditions for accessing the entities of the datacenter, and may be generated based at least on the network information in the declarative specification for the datacenter, and network artifacts from provisioning the network resources for the datacenter. Responsive to receiving a request to access an entity of a datacenter from a user, the system obtains credentials for the user and attaches the session policies. Responsive to determining that the credentials are used to access the datacenter from a set of access conditions that match the set of access conditions in the attached session policy, the cloud platform grants access.

Abstract: The present disclosure provides a combination of antisense RNA sequences and use thereof in the production of tilapia with degenerated sexual organs, belonging to the technical field of molecular biology and reproductive biology, the combination of antisense RNA sequences includes antisense RNA of steroidogenic factors SF1-1 and SF1-2; the nucleotide sequences of Anti-SF1-1-I, Anti-SF1-1-II, Anti-SF1-2-I and Anti-SF1-2-II are set forth in SEQ ID NO:1-SEQ ID NO:4 respectively. The method of the present disclosure introduces antisense RNA fragments into the eggs through the fertilization hole to realize effective and accurate targeted intervention for regulating the gene expression, and the method has the advantages of simple operation, minimal egg damage, high success rate, stable phenotype after breeding, and excellent application prospects.
