Abstract: A system receives ETL specification for processing stream data, including a transform operation represented using a database query specification. The system generates a dataflow graph of a sequence of database queries by decomposing the database query into a first database query that generates an intermediate results table, and a second database query that receives as input the intermediate results table and outputs data used for performing the transform operation. The system executes the sequence of database queries for performing the transform operation on stream data received from the source. When receiving an incremental data set, the system determines an output change set based on the received incremental data set by traversing an execution plan and processing each operator in the execution plan, and computing a change set of a particular operator from the change sets output by the one or more other operators based on the incremental data set.

Abstract: Recombinant human type III collagen for promoting angiogenesis, and a preparation method and an application method thereof are provided, which relate to the field of genetic engineering technologies. The amino acid of the recombinant human type III collagen is as shown in SEQ ID NO: 1. The method replaces nine different sites of a full-length natural type III collagen with a GFOGER sequence from type I collagen specifically binding to integrin sites, thereby enhancing promote angiogenic function without changing a total length of natural full-length amino acids. Meanwhile, the method replaces four natural integrin sites with lower adhesion rates, thus the recombinant type III collagen have higher adhesion, to further promote angiogenesis. Through this modification method, the angiogenesis rate will be increased by more than 37%, and the molecular weight of protein translated by the recombinant human type III collagen is moderate, making it easy to prepare.
