摘要:
A method for identifying a mechanism associated with a cellular response includes identifying molecules participating in the cellular response; accessing a database containing information characterizing molecular interactions; determining pathways connecting the identified molecules participating in the cellular response; and solving an optimization problem that includes determining a subset of the molecules and interactions having a minimum aggregate cost. The pathways include, nodes, each representing a molecule, and edges, each connecting a respective pair of nodes and representing an interaction between a respective pair of molecules represented by the respective pair of nodes. Nodes from a subset of nodes represent molecules identified as participating in the cellular response.
摘要:
To serve content through a content delivery network (CDN), the CDN must have some information about the identity, characteristics and state of its target objects. Such additional information is provided in the form of object metadata, which according to the invention can be located in the request string itself, in the response headers from the origin server, in a metadata configuration file distributed to CDN servers, or in a per-customer metadata configuration file. CDN content servers execute a request identification and parsing process to locate object metadata and to handle the request in accordance therewith. Where different types of metadata exist for a particular object, metadata in a configuration file is overridden by metadata in a response header or request string, with metadata in the request string taking precedence.

A method for operating a machine for identifying a mechanism associated with a cellular response includes identifying molecules participating in the cellular response, accessing a database containing information characterizing molecular interactions, determining pathways connecting the identified molecules participating in the response, and solving an optimization problem. The pathways comprise nodes, each representing a molecule, and edges, each connecting a pair of nodes and representing an interaction between a respective pair of molecules represented by the pair of nodes. The nodes includes a subset that represent molecules identified as participating in the cellular response. Solving an optimization problem comprises determining a subset of the molecules and interactions having a minimum aggregate cost, associating each participating node with a penalty value, associating each edge with a cost value, forming an objective function based on the penalty and cost values, and identifying the sub-network of nodes and edges that minimizes the objective function.

摘要:
Arbitrarily large document collections are processed by expanding a focus set having at least one initial metadocument into a plurality of subsequent metadocuments. The number of subsequent metadocuments is approximately equal to a predetermined maximum number. The subsequent metadocuments are then clustered into a predetermined number of new metadocuments, which are summarized and presented to a user. The focus set is redefined to include only user-selected new metadocuments.
