  • Publication number: 20110305909
    Abstract: Processes are described herein for preparing medical devices and other articles having a low-fouling surface on a substrate comprising a polymeric surface. The polymeric surface material may possess a range of polymeric backbones and substituents while providing the articles with a highly efficient, biocompatible, and non-fouling surface. The processes involve treating the substrate to reduce the concentration of chemical species on the surface of or in the substrate without altering the bulk physical properties of the device or article, and thereafter forming a grafted polymer layer on the treated substrate surface.

  • Publication number: 20110270533
    Abstract: Nucleic acid sequence mapping/assembly methods are disclosed. The methods initially map only a contiguous portion of each read to a reference sequence and then extends the mapping of the read at both ends of the mapped contiguous portion until the entire read is mapped (aligned). In various embodiments, a mapping score can be calculated for the read alignment using a scoring function, score (i, j)=M+mx, where M can be the number of matches in the extended alignment, x can be the number of mismatches in the alignment, and m can be a negative penalty for each mismatch. The mapping score can be utilized to rank or choose the best alignment for each read.

  • Patent number: 8010514
    Abstract: An improved system and method for flexible object placement and soft-state indexing of objects in a distributed object store is provided. A distributed object store may be provided by a large number of system nodes operably coupled to a network. A system node provided may include an access module for communicating with a client, an index module for building an index of a replicated data object, a data module for storing a data object on a computer readable medium, and a membership and routing module for detecting the configuration of operable nodes in the distributed system. Upon failure of an index node, the failure may be detected at other nodes, including those nodes that store the replicas of the object. These nodes may then send new index rebuilding requests to a different node that may rebuild the index for servicing any access request to the object.

  • Publication number: 20110178788
    Abstract: Predicate checking in conjunction with distributed systems can enable an investigating user to check predicates in the context of instance states and/or distributed states of a distributed system. In an example embodiment, a method entails accepting distributed system simulation data and performing a simulation of a distributed system using the distributed system simulation data to create distributed system simulated states. At least a portion of the distributed system simulated states are exposed. The exposed portion of the distributed system simulated states is retrieved and stored as exposed states for the distributed system. The exposed states for the distributed system are compared to predicate states for the distributed system. If an inconsistency is detected between the exposed states and the predicate states based on the comparing, at least one alarm is issued.

  • Patent number: 7962571
    Abstract: A method and system for retrieving data from devices in a way that seeks to preserve privacy and ensure the integrity of the retrieved data is provided. A retrieval system is implemented on a network of devices that communicate with each other via a secure communications link. Each device is directly connected to one or more “friend” devices that it trusts. The retrieval system operates by forwarding a request for data from one friend device to another friend device. Each friend device may optionally add data to the request until all the requested data is added. The request with the retrieved data is returned to the device that initiated the request.
