Abstract: The present disclosure provides methods and systems for detecting multiple different nucleotides in a sample. In particular, the disclosure provides for detection of multiple different nucleotides in a sample utilizing fewer detection moieties than the number of nucleotides being detected and/or fewer imaging events than the number of nucleotides being detected.

Abstract: Techniques for correlating changing hydraulic pressure differentials with interval control valve (ICV) movements are contemplated. In some aspects, the disclosed technology includes include methods for applying, by a surface controller, a series of differential pressure values to a hydraulic-open line, receiving, from a position sensor, a corresponding valve position for each of the differential pressure values, and calculating a lag time, a move speed and a response delay for each of the first series of differential pressure values. In some aspects, the method can further include steps for generating an ICV positioning model based at least in part on the lag time, the move speed, and the response delay calculated for each of the first series of differential pressure values. Systems and computer-readable media are also provided.

Abstract: A fuel injector includes an injector body, and a stack within the injector body, and having a nozzle supply passage therein. The stack includes a solenoid assembly having a solenoid housing piece with a fuel bore formed therein that includes a segment of the nozzle supply passage. The solenoid housing piece includes a solenoid housing material in a base state, and a solenoid housing material in a residual compressive stressed state, with the fuel bore being formed by the solenoid housing material in the residual compressive stressed state. Residual stresses may be imparted by ballizing, nitriding, carburizing, autofrettage, or still another technique.

Abstract: Methods and apparatus to recruit personnel are disclosed. A disclosed example recruiting system includes an electronic test administrator to present a test to a candidate and to record at least one of the candidate's answers to the test; and a recruiter interface to provide a recruiter with access to the at least one of the candidate's answers, to facilitate manual scoring of the at least one of the candidate's answers and to receive an assessment of the candidate's speaking voice.
