摘要:
Wireless stations (and their associated operation) making up a static, multi-hop wireless network are simplified because topological modeling and routing/scheduling decisions are shifted from the stations to a controller external to the network. The controller may determine routing paths and schedules for each of the wireless stations in a network based on the topology of a given network along with other network characteristics. Thereafter, the so-determined paths and schedules are sent to the associated wireless stations. By simplifying the operation of a wireless station, the amount of energy required to be used by each station may be reduced thereby maximizing the lifetime of the network.

A fluorescent immunoassay employing the interior surface of a capillary tube is provided. Devices to permit immunoassays using one or more capillary tubes, an apparatus for use with the devices, and a process for screening for analyte in a sample using the devices and apparatus are also provided. Samples suspected of containing analyte are added to a disposable self-contained sample tray containing one or more sample wells, mixed with a reagent, drawn into one or more spaced-apart capillary tubes held within a disposable cartridge connected to an analytical apparatus, reacted with a binding member on the surface of the capillary tube, washed to stop the reaction, and dried by the apparatus. The capillary tube is then exposed to a signal generation device to create a fluorescence signal that is detected using a signal detector. The apparatus determines the presence of the analyte and optionally determines the amount of analyte present in the sample, and presents the results to the operator.

Methods and a device are provided for adhering cells in a specific and predetermined position. The device comprises a plate defining a surface and a plurality of cytophilic islands that adhere cells which are isolated by cytophobic regions to which cells do not adhere. The cytophobic regions can be wide enough such that less than 10 percent of the cells adhered to the cytophilic islands are allowed to form bridges across the cytophobic regions and contact each other. Further, the islands or the regions or both may be formed of a self-assembled monolayer (SAM). The methods are for forming a patterned surface for a population of cells and for selectively manipulating individual cells formed on the surface of the plate of the device. Furthermore, the device is used in immobilization of cells at a surface and for controlling shape of the cells.

Providing a search engine with system configuration information. The system configuration information pertains to a system having a web server that provides content. For example, the content may be web pages associated with a web site, and the system may include hardware and software used to provide the content of the web site to end users. More particularly, the system can include one or more computer systems, web server software, application server software, and application programs that facilitate providing content. A search engine requests system configuration information from the web server. In response to the request, the web server provides system configuration information to the search engine. The search engine can use the system configuration information to reference portions of the content in an index. The index can be used to respond to a search query that involves content served by the web server.
摘要:
Computer-readable media, computer systems, and computing methods are provided for discovering applications using phone-number information. Initially, an application uploaded to an application marketplace is targeted. Phone numbers associated with the targeted application are discovered by identifying attributes of the targeted application from metadata associated therewith in the application marketplace, and identifying the phone numbers that reach at least one business affiliated with the targeted application or are relevant to the identified attributes of the targeted application. The associated phone numbers are mapped to the targeted application and maintained within an application manifest. Upon detecting user-initiated call-based operation(s) at a client device, the phone number(s) involved in the call-based operation(s) are compared against the application manifest to determine relevant applications. The relevant applications are distributed to the client device for presentation within a phone-number context, such as placing an outgoing call, receiving an incoming call, or reviewing a call-history log.

Invention relates to a single step preparation of alkali metal quinolate of general formula 1 wherein M=Lithium, sodium or potassium; R=H, alkyl (C1-C6), alkoxy, aryl, aryloxy, amino, amido or halogen (Cl, F, Br, I) which is substituted or unsubstituted with direct reaction of metal with 8-hydroxyquinoline. Substituted 8-hydroxyquinoline optionally have at least one substituent selected from the group consisting of alkyl, alkoxy, aryl, aryloxy, amino, amido at 2, 5 or 7 position. Halogen substituted 8-hydroxyquinolates are also prepared from this method in the yield of 90-95% from polar solvents like acetonitrile. These complexes are useful as light emitting and electron injecting materials in organic electronic devices. Also the doping of these materials in electron transport materials improves their electron mobility.

The present invention relates to protecting against, treating, and detecting Fusobacteria infections. Compositions and methods derived from nucleic acid and protein sequences of a 40 kDa Adhesin protein are provided to protect against, treat, and detect Fusobacteria infections in a subject. In one aspect, vaccines capable of inducing an immune response to a 40 kDa Adhesin protein are used to protect against Fusobacteria infection. Also, nucleic acid molecules, proteins, immunogens, antibodies, and antisense molecules derived from the sequences of the 40 kDa Adhesin protein may be used to protect against, treat, and detect Fusobacteria infections in a subject.
