    摘要： A highly efficient access control system and method employing XACML standard based policies and rules provides high performance resource access control of information systems of large enterprises. The system and method extracts plain rules from the XACML policies, transforms the plain rules into atomic rules, and compresses and indexes the atomic rules for fast lookup and retrieval. Access requests are decomposed into atomic requests which are compressed using the same value mapping as the rules. Index keys derived from compressed atomic request triplets are used to look up applicable rules which are used to evaluate requests for access to information system resources.

    摘要： The invention herein comprises amyloid beta-derived diffusible ligands (ADDLs), compositions comprising ADDLs, ADDL-surrogates, ADDL-binding molecules, and methods of using any of the foregoing compounds and compositions. ADDLs comprise amyloid β protein assembled into soluble, globular, non-fibrillar, oligomeric structures capable of activating specific cellular processes. The invention also comprises methods of generating ADDL-specific antibodies and methods of using ADDL-specific antibodies for assaying the formation, presence, receptor protein binding and cellular activity of ADDLs, as well as using such antibodies to detect compounds that block the formation or activity of ADDLs, and methods of identifying such compounds. The invention further provides methods of using ADDL-specific antibodies in modulating ADDL formation and/or activity, inter alia in the treatment of learning and/or memory disorders.
