摘要:
Optoelectronic devices, materials, and associated methods having increased operating performance are provided. In one aspect, for example, an optoelectronic device can include a semiconductor material, a first doped region in the semiconductor material, a second doped region in the semiconductor material forming a junction with the first doped region, and a laser processed region associated with the junction. The laser processed region is positioned to interact with electromagnetic radiation. Additionally, at least a portion of a region of laser damage from the laser processed region has been removed such that the optoelectronic device has an open circuit voltage of from about 500 mV to about 800 mV.

In processing a query on multidimensional data in a multidimensional schema, a multidimensional database server performs various processes to limit the amount of data that is extracted from the database and presented to a relational database server in response to the request. A subset of data is identified to extract from the multidimensional data, based on the query. In various embodiments, cell-filtering, measure-filtering, and column-filtering criteria identified from the query are used to filter the subset of data, in order to return a minimized set of multidimensional data values from the subset of data. Therefore, computational resources are conserved with respect to further processing by the relational database server in response to the query.

In one aspect, the present invention provides a silicon photodetector having a surface layer that is doped with sulfur inclusions with an average concentration in a range of about 0.5 atom percent to about 1.5 atom percent. The surface layer forms a diode junction with an underlying portion of the substrate. A plurality of electrical contacts allow application of a reverse bias voltage to the junction in order to facilitate generation of an electrical signal, e.g., a photocurrent, in response to irradiation of the surface layer. The photodetector exhibits a responsivity greater than about 1 A/W for incident wavelengths in a range of about 250 nm to about 1050 nm, and a responsivity greater than about 0.1 A/W for longer wavelengths, e.g., up to about 3.5 microns.
摘要:
A method, apparatus, system, and signal-bearing medium that, in an embodiment, provide status and commands for manipulating contained-messages. A received e-mail message may contain the contained-messages, e.g., forwarded or replied-to messages, either embedded in the received e-mail message or as an attachment. The status may relate to not only the contained-message, but also may relate to another version of the contained-message that was previously received separately from the e-mail message that contains the contained-message. Commands may be directed to the received e-mail and its contained-messages, the contained-messages, and the version of the contained-messages that were separately received.
摘要:
Multiple writers can make permanent changes to data objects, while the performance is improved and data consistency is ensured. A database management system comprises a database containing a plurality of objects, and, possibly, a plurality of analytic workspaces, each analytic workspace containing at least some of the plurality of objects in the database, wherein changes made to a an object in a database private view are not written to a corresponding object in the database unless write access on the object has been given to the database private view, and wherein the database management system is operable to give write access on each of the plurality of objects in the database to database private views individually.
摘要:
A polyalkylene glycol based lubricant composition that contains specified rust inhibitors and antioxidants has lowered operating temperature and is particularly suitable for use in worm drive gearboxes. The rust inhibitors consist of an N-acylo arcosine and an imidizole while the antioxidant consists of an alkylated diphenyl amine and a hindered phenol.
