摘要:
An open hole is drilled with coiled tubing that has an electric line. At the conclusion of drilling the drilling bottom hole assembly is removed and a liner running tool is connected between the coiled tubing and the liner. The electric line remains in the coiled tubing but spacers can be added to keep the lower end of the electric line away from the running tool. A wiper plug has a passage therethrough and a movable stinger that can hold open a pair of flapper valves. The liner is released from the running tool and cement is delivered through the stinger with a bit of excess that is above the running tool. The lifting of the stinger with the coiled tubing closes the flappers and allows circulation out of excess cement. Setting down on the coiled tubing allows a seal to re-engage in the deployment sleeve, allowing pressure to be placed against the wiper plug, such that it can be launched to displace the remaining cement within the liner into the annulus around the liner.

The present invention is a method for seaming a polyimide material. The method involves forming an interface between multiple the polyimide materials. Next, heat is applied to the interface to soften the polyimide material. The temperature of the heat source is below the melting point of the polyimide material. Finally, pressure is applied to the interface to create a seam between the polyimide materials.

A method and system are provided in a wireless communications system comprising a plurality of nodes (users) working cooperatively. The system provides cooperative diversity by allowing nodes to actively share their antennas and other resources to obtain spatial diversity. The nodes receive the same message (information data) from a common source. Each node enhances the reliability of the message with a modern forward error correction (FEC) code, converts the FEC encoded message into an ensemble of symbols, divides the ensemble of symbols into packets, modulates, dithers and transmits the packets to a receiving node. The dithering process is performed by varying the signal amplitude, phase, frequency and/or symbol timing of the modulated packets. A unique dither pattern is assigned to each node. The receiving node captures a composite signal comprising the transmitted packets of all or most of the transmitting nodes in the cooperative communications system. Because the transmitted packets are dithered independently in phase and/or amplitude, spatial diversity is transformed into temporal diversity.

Systems and methods for selecting a ranker for statistical natural language processing are provided. One disclosed system includes a computer program configured to be executed on a computing device, the computer program comprising a data store including reference performance data for a plurality of candidate rankers, the reference performance data being calculated based on a processing of test data by each of the plurality of candidate rankers. The system may further include a ranker selector configured to receive a statistical natural language processing task and a performance target, and determine a selected ranker from the plurality of candidate rankers based on the statistical natural language processing task, the performance target, and the reference performance data.

The present invention relates to a refined and detailed molecular model of the α2⊕1 integrin I-domain, especially the MIDAS and to the use of such a model for designing novel integrin modulators, especially α2β1 integrin modulators. The present invention further relates to novel α2β1 I-domain modulators, which are of therapeutic potential. The present invention further relates to specific families of small molecule modulators interacting with collagen receptors, tetracyclic polyketides and sulfonamides. The present invention further relates to the use of such modulators for the manufacture of medicaments for thrombosis, inflammation and/or cancer
摘要:
A multi-state spin based memory cell uses a pair of ferromagnetic layers. A first ferromagnetic layer can be set to any known state k from a set of n different states by adjusting a magnetic orientation of such layer. The relationship of the first ferromagnetic layer and a second magnetic layer can thus correspond to a value of a data item in a non-volatile multi-bit memory cell.

The portable cooler is a portable refrigeration system for selectively and adjustably cooling a removable container, such as a beer keg, for example. The portable cooler includes a housing that defines an open interior region for removably receiving the keg. A door is pivotally mounted to the housing, providing the user with selective access to the open interior region. A refrigeration device is mounted within the housing, adjacent the container, and may be powered by an external power supply or by rechargeable batteries, also received within the housing. Wheels are pivotally mounted to a lower end of the housing, and a handle is mounted to an upper end of the housing, allowing the user to selectively transport the housing and keg.

A conference server enables collaborative communications among a variety of client processes of varying configurations all operatively coupled over a computer network to each other and to the server. The server receives audio streams from participating client processes in a conference, selects which audio streams are active, and broadcasts one or more of the active audio streams to the client processes participating in the conference depending on the clients receiving capabilities and the conference parameters. The client processes receiving multiple active audio streams perform mixing locally at the client node. Without having to perform mixing at the server, resources are saved and the number of simultaneous participating client processes to the conference may be increased accordingly. The server is further capable of simultaneously accommodating multipoint clients and non-multipoint H.323 clients, as well as operating in multiway and “push to talk” modes.
