Abstract: A statistical methodology is disclosed to provide time-to-event estimates for oilfield equipment. A method according to the present invention extracts unbiased information from equipment performance data and considers parameters interactions without recourse to data thinning.

Abstract: Protein identification in a complex sample begins by selecting a database having proteins likely to be in the sample. In-silico digestion is performed and a target peptide is selected from produced peptides. The masses of the Y- and B-ion fragments of the target peptide are determined. These masses are used to search previously obtained low- and high-energy AMRTs obtained from LC/MS analysis of the complex sample for masses on the list. Any mass observed in the data within a detection threshold are considered a hit. If enough hits accumulate in a given retention time, the target peptide is identified as being in the sample. The list of peptides identified in the complex sample can be used to identify the proteins present in the sample, track the chromatographic retention times of peptides between samples, and quantitate the peptides and proteins present in complex samples.

Abstract: A method and wireless multi-cell communication system for providing high speed downlink packet access (HSDPA) services. The system includes a radio network controller (RNC) in communication with a plurality of base stations. The RNC sends a control signal to at least one base station having a plurality of timeslots, e.g., in a time division duplex (TDD) system and/or frames including transmission timing intervals (TTIs), e.g., in a frequency division duplex (FDD) system assigned thereto for the establishment of HSDPA channels. The control signal indicates a maximum allowed HSDPA transmit power for each of the timeslots and/or TTIs. The base station sends a feedback signal to the RNC indicating the results of measurements of the power of the transmitted HSDPA timeslots and/or TTIs during a predetermined time period.

Abstract: A mixer in an RF demodulator includes a transconductance amplifier that converts an RF input voltage (Vin), applied to the base of a first bipolar transistor, to a first output current. The first output current contains third order intermodulation (IM3) products. An IM3 canceller is connected in parallel with the transconductance amplifier. The base of a second bipolar transistor in the IM3 canceller is coupled to the DC component of Vin, and the AC component of Vin is coupled to the emitter of the second bipolar transistor, such that the currents though the first bipolar transistor and the currents through the second bipolar transistor change oppositely. The collectors of the transistors are coupled together. The values of components in the IM3 canceller are set so that the current generated by the IM3 canceller substantially cancels IM3 distortion in the first current or other current generated in a demodulator of Vin.

A second support is supported on the first support, and is rotatable with a first direction being the axis. A third support is supported on the second support, and is movable in the axial direction of the cryostat as viewed from the second support. The cryostat is supported on the third support, and moves integrally with the third support.

Furthermore this content control signal provides resistance to a circumvention device. For example, the circumvention device is unable to remove sufficiently the content control signal, and content control is maintained.
