Abstract: In one embodiment, a method for storing a snapshot of data in a database includes creating a root indirection set for the snapshot of data and maintaining a deleted pattern in the database. The deleted pattern is not removed from a pattern set for a node in a table of the database when the pattern is deleted in the database. The method includes providing access to the snapshot of data using the created root indirection set, the created root indirection set accessing the deleted pattern.

Abstract: A paperless coupon redemption system, consisting of manufacturers or distributors loading coupons into a database for use by consumers. Consumers being able to access an internet interface to view, find and select coupons, and redeem them at the point of sale with an issued PVC card containing a unique reference number. The point of sale terminals are equipped with a hardware or software module which facilities the interaction between the POS machines and coupon database. The hardware and software modules work by collecting the UPC codes of products to be purchased, and transmitting these to a server along with the customer reference number. The server returns the UPC codes of applicable coupons, which are then transmitted into the POS system.

Abstract: A database is created from a set of data by identifying the patterns in the data set, storing the patterns in a memory device, and generating a representation of the database structure using pointers to the stored patterns. The use of pointers to store the patterns can greatly reduce the amount of memory or other space required to store the data set by replacing duplicate patterns with additional pointers, which are normally considerably smaller in size. In addition, the use of pointers may allow for more rapid searching, sorting, and other operations on the database. The representation of the database may use pointers in a tree structure to identify nodes and reduce searching and other operations. A tree structure representation of a table may use a pointer to a pattern for the base leaf node (e.g., nodes that do not branch) while using pointer pairs to represent branching nodes.

Abstract: Quiescence is induced in cells using indole compounds. Expression continues from extra-chromosomal vectors within the cells during quiescence, while chromosomal expression is suppressed. The cells may be used as factories for the production of large amounts of polypeptides of interest, particularly polypeptides which normally have an adverse effect on cell viability or growth. Expression from an extra-chromosomal vector of interest may be monitored, in view of the reduced background expression from the chromosome. Vector copy number may be amplified. Cell cycles may be synchronized.

Abstract: Disclosed are methods for generating mycolic acid bacterial biosensors for particular analytes (especially industrial pollutants) by the use of innovative methods for isolating DNA encoding an inducible promoter which is induced in response to the specific analyte (and/or associated operon proteins), the methods generally comprising the steps of: (a) culturing a source of mycolic acid bacteria in a selective medium containing said specific analyte and being selective for oligotriphic bacteria; (b) identifying mycolic acid bacteria capable of subsisting on said medium, especially those which do not display catabolic repression; (c) extracting DNA from said mycolic acid bacteria; (d) incorporating said DNA into vectors, such as various shuttle vectors; (e) cloning said vector into a suitable host cell (which may be E.

Abstract: The invention features a bacterial cell containing an extra-chromosomal vector that includes an inducible rcd gene, wherein the cell, when placed in broth culture, enters quiescence on expression of the rod gene.
