Title: A system and method for creating, executing and maintaining cross-enterprise processes
Inventor: NIBBELINK MITCHELL W
IPC: G06Q10/00
Filed: 1998-01-23
Abstract: A system and method for creating, executing, and maintaining shared, automated business processes across distributed organizations comprises capabilities that enable interoperation among heterogeneous information systems. The system includes a plurality of independent communicating subsystems called sites that have a server with common means of representing and executing shared public process definitions and private process definitions. Process execution comprises coordinated inter-site message exchanges that are coupled with controlled sequences of actions that are local to each of the sites. The public process definition or module captures interactions among the independent sites. Interactions include communication events in which one site sends a message of a known type to another site. Each definition specifies a set of valid sequences of communication events among the participating sites.  Associated with any public process definition is a set of lower level or private process definitions or modules. The private process definition specifies a set of possible local actions that can be executed at the site when that particular public process node is executed. In the preferred embodiment, the private process definition is defined in terms of constructs such as operating parameters and software application interactions.

Title: Method and apparatus for accessing multidimensional data
Inventor: NOURI KOOROSH M
IPC: G06F17/24
Filed: 1999-10-21
Abstract: Retrieving multidimensional data from a data source and displaying the data in a familiar and pre-existing user interface automatically propagates user-created formulas thereby eliminating the need for users to re-enter formulas. A data representation of the multidimensional data is sent to a query processor which creates row and column structures. These structures are manipulated based on a user action, such as zoom-in, and a multidimensional data output tree showing a hierarchy of the multidimensional data. Also created is a blueprint containing instructions on insertions and deletions to be carried out by the program associated with the pre-existing user interface, such as a spreadsheet program. Once the blueprint is interpreted by the program, typically through a data representation manipulator or common spreadsheet layer, the user interface is configured to accommodate the returned multidimensional data. Once the user interface is populated with the data, the program, such as the spreadsheet program, adjusts the user-created formula cell designations to reflect the new configuration.

Les composés préférés selon l'invention sont des esters. L'invention concerne également des procédés permettant d'utiliser ces nouveaux composés aux fins d'inhiber les réponses intracellulaires, à médiation céramide, à des stimuli in vivo (en particulier le TN-.alpha.). Ces procédés sont susceptibles d'être utilisés pour réduire des réponses inflammatoires (par exemple, après une angioplastie), limiter la fibrose (par exemple, du foie lors d'une cirrhose), inhiber la sénescence cellulaire, l'apoptose cellulaire et la suppression de la réponse immunitaire de la peau induite par U.V. L'invention a également trait à des composés présentant une solubilité dans l'eau accrue.
