Abstract: Computer implemented methods, systems, and computer program products include program code executing on a processor(s) that obtain a query comprising a JOIN statement that references two or more tables in the one or more remote databases. The program code determines, for each table of the two or more tables, whether executing the JOIN statement utilizes system resources above a pre-defined allotment. Based on determining, for at least one table the program code generates a filter for the at least one table based on an intersection between predicates in the query. The program code applies the filer to the at least one table to fetch results for the query and exclude unrelated data from the fetching.

Each mapped store procedure includes a subset of queries that are applicable to a corresponding datasource from the set of queries in the procedure. These mapped store procedures are forwarded to the corresponding datasource for storage on the corresponding datasource. In response to a running of the procedure, execution of the mapped store procedure is commenced on each of the corresponding datasources on which they are stored.

The approach identifies a first set of parameters associated with the statements of the SQL set. The approach creates a merged SQL statement based on one or more matching parameters of SQL statements in the SQL set. The approach binds a second set of parameters associated with the merged SQL statement to the merged SQL statement. The approach generates a SQL statement based on the merged SQL statement. The approach generates a remote SQL statement based on the SQL statement. The approach executes a commit statement on the remote SQL statement.

Abstract: CD47+ disease cells such as cancer cells are treated using a combination of CD47 blocking agent and poly-(ADP-ribose) polymerase (PARP) inhibitor. The CD47 blocking agent can be SIRP?Fc and the PARP inhibitor niraparib. The anti-cancer effect of niraparib is enhanced in the presence of SIRP?Fc. Specific combinations include SIRP?Fc forms that comprise an Fc that is either IgG1 or preferably IgG4 isotype. These combinations are useful particularly to treat solid tumours and blood cancers including lymphomas, leukemias and myelomas.

Abstract: Methods, systems, and devices for techniques for logical-to-physical information compression are described. In some cases, a memory system may compress a logical-to-physical (L2P) mapping to expand the quantity of physical addresses mapped by the L2P mapping. For example, if a set of consecutive entries of an uncompressed L2P mapping includes consecutive physical addresses, the memory system may compress the consecutive entries into a single entry which includes a starting physical address of the consecutive physical addresses. Additionally, the memory system may include an indication of a starting logical address corresponding to the starting physical address in the compressed entry. To identify a physical address within the compressed entry, the memory system may determine an offset between a logical address corresponding to the physical address and the starting physical address using the indication, and may apply the offset to the starting physical address to determine the physical address.
