Abstract The gravitational-wave detectors outputs from the LIGO and Virgo collaborations have been a source of scientific results prime importance in various domains such as astrophysics, cosmology or fundamental physics. With upgrades their improved sensitivities, new challenges are set for these instruments calibration. A calibration method based on local variations Newtonian gravitational fi...

In June 2005, a pilot program was implemented in Canadian laboratories to monitor the performance of the Abbott human immunodeficiency virus types 1 and 2 (HIV-1/2) gO enzyme immunoassay (EIA). Two different external quality control (QC) reagents and a "real-time" software analysis program were evaluated. In November 2005, higher-than-expected calibrator rate values in these kits were first rep...

Accurate laboratory tests for the diagnosis of active human herpesvirus 8 (HHV-8) infection are becoming essential to study the pathogenesis of HHV-8-associated tumors and for the clinical management of HHV-8-infected individuals. We have developed a highly sensitive, calibrated quantitative real-time PCR assay for the measurement of cell-free HHV-8 DNA in body fluids, based on the addition of ...

Using knowledge of the low-frequency radio sky and the simulated observational capabilities of the Long Wavelength Array (LWA) we present a feasible method for the LWA to probe the overall structure of the ionosphere above the LWA. Such measurements could serve as the initial step in calibrating the ionospheric phases that distort astronomical images, thereby allowing the LWA to reach its full ...

Abstract This article displayed the method of partial discharge (PD) measurement in high-voltage insulator and calibrating effective element (capacitor) to enhance PD signal. The cavity shapes were plate–plate, cylindrical spherical inside solid insulator. proposed system enables from detecting reverse main discharge, respectively, through rise tail time pulses. that took place was bounded with...

In this paper, we address the problem of speaker verification in conditions unseen or unknown during development. A standard method for consists extracting embeddings with a deep neural network and processing them through backend composed probabilistic linear discriminant analysis (PLDA) global logistic regression score calibration. This is known to result systems that work poorly on different ...

The Submillimetre Common User Bolometer Array 2 (SCUBA-2) is the James Clerk Maxwell Telescope's continuum imager, operating simultaneously at 450 and 850~$\mu$m. SCUBA-2 was commissioned in 2009--2011 since that time, regular observations of point-like standard sources have been performed whenever instrument use. Expanding calibrator observation sample by an order magnitude compared to previou...
