Abstract: A system and method for reconstructing pathways in large genetic networks from genetic perturbations comprises an analysis method and system that applies a recursive algorithm for determining the path between every gene pair in an arbitrarily large genetic network from large-scale gene perturbation data and reconstructs all direct and indirect regulatory gene interactions in the network. Graph theory mathematics is applied to genetic network reconstruction in the following manner: Genetic perturbation data is used to identify all genes accessible from a perturbed gene to generate an accessibility list for the gene. Graph theory mathematics is applied to the accessibility list and its graph to determine a condensation of the graph as defined by the condensation's accessibility list. Graph theory mathematics is applied to the accessibility list, such as through a recursive algorithm performed on a desktop computer, to obtain an adjacency list for the gene that characterizes a genetic network.

Abstract: A method is described for the selection and assignment of keyboard access mnemonics and accelerator key combinations as part of the application software development process. After determining application functions and categories that require assignment, mnemonics and accelerators are assigned using pre-established recommendations, assignment rules and/or user assignment. If the assignments are made automatically, each function is first evaluated on the basis of usage likelihood and then prioritized before assignment begins in order to maximize the number and quality of successful assignments. In the alternative, assignments can be made on a function-by-function basis.
