20110054590VASCULAR PROSTHESIS WITH STRESS RELIEF SLOTS - A vascular prosthesis comprises generally tubular body placeable in contracted and expanded states and has an axial length and a circumferential dimension in the expanded state. The body includes a series of circumferential elements having first lengths. First and second connectors have connector lengths and join alternating ends of adjacent circumferential elements. The first length plus the connector lengths joined thereto equal a total circumferential length. Each connector length is between 2.5% and 25% of the total circumferential length. Adjacent circumferential elements and connectors extending therefrom are separated by a stress relief slot having a relief slot length of more than 50% and less than 95% of the total circumferential length. The stress relief slots have narrow width portions over a majority of the relief slot lengths, the narrow width portions having lateral dimensions of no greater than about 3 mm.03-03-2011
20110218608Vascular Prosthesis Delivery System and Method - A vascular prosthesis delivery system comprises a radially self expandable vascular prosthesis and a delivery sheath with a lumen with a smaller diameter storage region and a larger diameter delivery region. A prosthesis is housed within the storage region and is movable into the delivery region for delivery at a target site within a patient. The delivery force required to move the prosthesis from the delivery region into the patient can be less than the force required to move the prosthesis from the storage region into the delivery region. In some examples, the storage region defines a tapered lumen expanding in diameter in a distal direction. In some examples, the storage and delivery regions are generally coextensive and define a tapered lumen expanding in diameter in a distal direction. A method stores a vascular prosthesis in the storage region and delivers it to a target site from the delivery region.09-08-2011

20090037117Differential Dissociation and Melting Curve Peak Detection - Systems and methods are provided for processing a melting or dissociation curve of a DNA or other sample, for example, during PCR processing. In some embodiments, detection of the melting point and melting curve behavior can be enhanced by taking a derivative of the curve, and detecting peaks in the differential dissociation curve. In some embodiments, the derivative operation can comprise the use of edge-processing, or other detection algorithms. In some embodiments, the dissociation analysis can comprise removing low-frequency (or pedestal) components of the differential dissociation curve. In some embodiments, the differential dissociation curve can exhibit a smoothed or more regular appearance than the raw detected data.02-05-2009
20090204353Methods for the Analysis of Dissociation Melt Curve Data - Methods are provided that operate on raw dissociation data and dissociation curves to generate calibrations of the detected data and to further improve analysis of the data. The data can be taken from each support region of a multi-region platform, for example, from each well of a multi-well plate. Each support region can be loaded with portions of the same sample. In some embodiments, a dissociation curve correction can be calibrated for the sample, prior to a run of an experiment using such sample. In some embodiments, a method is provided for generating a melting transition region of dissociation curves that show the melting characteristics of the sample. In some embodiments, dye temperature dependence correction can be performed on the dissociation curve data to further improve analysis. In some embodiments, a feature vector can be derived from the melt data, and the feature vector can be used to further improve genotyping analysis of the dissociation curves.08-13-2009
20110105345Methods for the Analysis of High Resolution Melt Curve Data - The present application provides for various embodiments of methods for the analysis of high resolution melt (HRM) curve data; where statistical assay variations in melt curve data may result from system noise in an analysis system. Such system noise may arise from various sources, such as the thermal non-uniformity of a thermocycler block in a thermal cycler apparatus, a detection system, etc. Additionally, various methods for the analysis of HRM curve data may provide an identification of a sample without the need for a user inputted information.05-05-2011

20120059744Attention Economy For Attention To Messages, Tasks and Resources - A centrally tracked artificial currency is provided within the context of an enterprise. This currency serves as a unit of account, medium of exchange, and store of value in a corporate “attention economy.” Users (typically coworkers) in the enterprise are allotted a base number of currency units, which they can earn, exchange, and spend in a variety of ways to signal importance and “purchase” attention of others, or priority for other organization resources. In one aspect, senders of messages can specify an amount of currency to be associated with the message, so that recipients can see the specified amount before deciding whether to read the message. Once such a system is in use, it facilitates exchange of value based on user-created transactions regarding behavior, communication, resources, incentives, and priorities.03-08-2012

20110299414PRESERVING QUALITY OF SERVICE ACROSS TRILL NETWORKS - Systems and techniques for processing and/or forwarding packets are described. An ingress switch can use a QoS mapping mechanism to map a first set of Quality of Service (QoS) bits in a packet received from a customer to a second set of QoS bits for use in a Transparent Interconnection of Lots of Links (TRILL) packet which encapsulates the packet. The first set of QoS bits can be different from the second set of QoS bits. The TRILL packet can be processed and/or forwarded in the network based on the second set of QoS bits. At the egress switch, the TRILL packet can be decapsulated and the original packet with the original QoS bits (or QoS bits that are different from the original QoS bits) can be forwarded to the customer's network. In this manner, some embodiments of the present invention can preserve the QoS bits across a TRILL network.12-08-2011
20110299533INTERNAL VIRTUAL NETWORK IDENTIFIER AND INTERNAL POLICY IDENTIFIER - Systems and techniques for processing and forwarding packets are described. Some embodiments provide a system (e.g., a switch) which determines an internal virtual network identifier and/or an internal policy identifier for a packet based on a port on which the packet was received and/or one or more fields in the packet. The system can then process and forward the packet based on the internal virtual network identifier and/or internal policy identifier. In some embodiments, the system encapsulates the packet in a TRILL (Transparent Interconnection of Lots of Links) packet by adding a TRILL header to the packet. In some embodiments, the scope of an internal virtual network identifier and/or an internal policy identifier may not extend beyond a switch or a module within a switch.12-08-2011
20110299536METHOD AND SYSTEM FOR LINK AGGREGATION ACROSS MULTIPLE SWITCHES - One embodiment of the present invention provides a switch. The switch includes a forwarding mechanism and a control mechanism. During operation, the forwarding mechanism forwards frames based on their Ethernet headers. The control mechanism operates the switch in conjunction with a separate physical switch as a single logical switch and assigns a virtual switch identifier to the logical switch, wherein the virtual switch identifier is associated with a link aggregation group.12-08-2011
