Abstract: A computer-implemented method, system, and/or computer program product optimizes an order of execution of column join operations. A first partitioning of the first data column splits the first data column into first subsets of rows. A second partitioning of the second data column splits the second data column into a second subsets of rows. Cardinalities of sub-tables derived by a respective joining of the subsets of rows of the first and second data columns are estimated, based on the first and second value frequency information. An order of execution of multiple join operations is then optimized based on the estimated cardinalities of the sub-tables.

Abstract: An approach is provided for securing communication between a server computer and a client computer. A first string is sent to the client in response to a request to permit an application being executed by the client computer to access a first function. A second string that includes a parameter of a second function is received. The second string is a result of a conversion of the first string to a command and an execution of the command by the client. The second string is converted into a call to the second function. Using the call, the server executes the second function. Based on a result of the execution of the second function and without requiring an implementation of native code, the server determines whether to (i) permit the application to access the first function or (ii) prevent the application from accessing the first function.

Abstract: An administrator may wish to limit the number of tuples that may be spawned as a result of a first tuple entering an operator graph. A first stream operator may receive a first tuple in order to perform an operation on the first tuple to generate a second tuple. The first stream operator may determine whether it is permitted to generate the second tuple by comparing the first tuple's tuple spawn counts to a tuple creation policy. If the first stream operator is permitted to generate the second tuple, the first stream operator may perform the operation on the first tuple and generate the second tuple.

Abstract: Hybrid pre-patterns were prepared for directed self-assembly of a given block copolymer capable of forming a lamellar domain pattern. The hybrid pre-patterns have top surfaces comprising independent elevated surfaces interspersed with adjacent recessed surfaces. The elevated surfaces are neutral wetting to the domains formed by self-assembly. Material below the elevated surfaces has greater etch-resistance than material below the recessed surfaces in a given etch process. Following other dimensional constraints of the hybrid pre-pattern described herein, a layer of the given block copolymer was formed on the hybrid pre-pattern. Self-assembly of the layer produced a lamellar domain pattern comprising self-aligned, unidirectional, perpendicularly oriented lamellae over the elevated surfaces, and parallel and/or perpendicularly oriented lamellae over recessed surfaces. The domain patterns displayed long range order along the major axis of the pre-pattern.
