Contrary to our hypothesis, there was no evidence in the current sample that vocabulary skill mediated the relationship between speech perception and PA. Each individual path was adequately powered at the current sample size. Conclusions The overall model provided evidence for a continued relationship between speech perception, measured by perceptual acuity of the sound in error, and PA in school-aged children with residual speech errors. Thus, measures of speech perception remain relevant to the assessment of school-aged children and adolescents in this population.

Scholars have examined overall effectiveness of specialty probation programs, probation officers' roles as street-level bureaucrats, and the impact of the mental health caseload probation officer and probationer relationship on successful completion. Less attention, however, has been placed on examining how the officers supervising these specialty caseloads perceive their roles as mental health probation officers and how they use discretion in their caseload management. The current study examines the narratives of 24 specialty mental health caseload probation officers and supervisors to understand how discretion is used on a problem-solving caseload and how discretionary decision-making may impact probationer outcomes.We present a new design for a pulsed supersonic-beam source, inspired by the Even-Lavie valve, which is about four times more energy efficient than its predecessor and can run at more than double the repetition rate without experiencing resonances. Its characteristics make it a better candidate as a source for cryogenic-related experiments as well as spectroscopy with rapidly pulsed lasers. The new design is also simpler to build and is more robust, making it accessible to a larger portion of the scientific community.Energy Dispersive Inelastic X-ray Scattering (EDIXS) is a reliable technique for the discrimination and characterization of local chemical environments. By means of this methodology, the speciation of samples has been attained in a variety of samples and experimental conditions, such as total reflection, grazing incidence, and confocal setups. Until now, due to the requirement of a monochromatic and intense exciting beam, this tool had been applied using exclusively synchrotron radiation sources. We present, for the first time, results of test measurements using EDIXS for chemical characterization implemented in a conventional x-ray tube based laboratory. The results show good discrimination between different iron compounds under study, suggesting the real possibility of rutinary chemical state characterizations of samples by means of EDIXS using a conventional x-ray tube.The parameters of a stereo camera directly determine the accuracy of a stereo vision positioning system. In this paper, the relationship between camera parameter error and positioning error is established by using the geometric analysis method with a clear physical meaning. The error models of the relative position error and camera resolution error of the stereo camera are established. The relative position error of the stereo camera is represented by the rotation and translation of the coordinate system, and the positioning error is derived from image coordinates through the pinhole camera model. For the camera resolution error, the two pixels of the stereo camera are projected into an octahedral uncertain region in space. We use geometric methods to derive the maximum size of the octahedron in the three-axis direction. The maximum size in the three-axis direction is used to evaluate the impact of camera resolution errors. The depth of field and angle of view are used to represent the measured area. The effects of resolution error and camera parameters on the measurement error of each axis are analyzed. Finally, a large number of simulations verified our conclusion. By comparing the effects of the magnitude of the error, we can conclude that the baseline and pixel size of the camera have a greater impact on the positioning accuracy.Optical emission spectroscopy is widely used in semiconductor and display manufacturing for plasma process monitoring. However, because of the contamination of the viewport, quantitative analysis is extremely difficult; therefore, qualitative analysis is used to detect species in the process. To extend plasma monitoring in advanced precise processes, the contamination problem of the viewport must be solved. We propose a new spectrum monitoring apparatus with a roll-to-roll transparent film window for optical diagnostics of a plasma system. By moving a transparent film in front of the viewport, contamination in the emission light path becomes negligible. However, the speed of the film should be optimized to reduce the maintenance period and to minimize measurement errors. We calculated the maximum thickness of SiO2, Si3N4, ITO, and the Ar/CHF3 plasma contaminant to suppress the electron temperature error measured by the line-intensity-ratio within 2% at 2 eV. The thickness of the Si3N4, ITO, and Ar/CHF3 plasma contaminant should be thinner than 12.5 nm, 7.5 nm, and 100 nm, respectively.The breakthrough MEMS-Fabry-Perot interferometry spectral analyzer (C15712) offers engineers and scientists a compact, inexpensive and versatile module to expand the range of applications in near infrared spectroscopy.We have characterized and mapped the electrical cross talk (ECT) of a frequency division multiplexing (FDM) system with a transition edge sensor (TES) bolometer array, which is intended for space applications. By adding a small modulation at 120 Hz to the AC bias voltage of one bolometer and measuring the cross talk response in the current noise spectra of the others simultaneously, we have for the first time mapped the ECT level of 61 pixels with a nominal frequency spacing of 32 kHz in a 61 × 61 matrix and a carrier frequency ranging from 1 MHz to 4 MHz. We find that about 94% of the pixels show an ECT level of less than 0.4%. Only the adjacent pixels reach this level, and the ECT for the rest of the pixels is less than 0.1%. We also observe higher ECT levels, up to 10%, between some of the pixels, which have bundled long, parallel coplanar wires connecting TES bolometers to inductor-capacitor filters. BAY-293 In this case, the high mutual inductances dominate. To mitigate this source of ECT, the coplanar wires should be replaced by microstrip wires in the array.
