Consequences of Departure from Normality on the Properties of Calibration Estimators [PDF]
, 2005 This paper considers the classical and inverse calibration estimators and discusses the consequences of departure from normality of errors on their bias and mean squared error properties when the errors in calibration process are ...

Calibrated EWMA estimators for time-scaled surveys with diverse applications
HeliyonRecently, several memory-type mean estimators (including ratio, product, and logarithmic) have been developed. These estimators rely on exponentially weighted moving average (EWMA), which incorporate both historical and present sample data.

Estimation of Calibration Uncertainties in the Detector-Based Photometric Calibrations
Acta Physica Polonica A, 2008 Uncertainty evaluations in the photometric calibrations and established uncertainty budgets at National Metrology Institute of Turkey (TUBITAK-UME) are presented. Uncertainty analyses are cover calibrations of the luminous intensity, the luminous flux and the luminance properties of the optical light source. The combined uncertainty in each photometric

FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

FEBS Open Bio, EarlyView.Erythropoietin administration suppresses hepatic soluble epoxide hydrolase (sEH) expression, leading to increased CYP‐derived epoxides. This is associated with a shift in hepatic macrophage polarization characterized by reduced M1 markers and increased M2 markers, along with reduced hepatic inflammation, suppressed hepatic lipogenesis, and attenuated ...

Optimal calibration in immunoassay and inference on the coefficient of variation [PDF]
, 2008 This thesis examines and develops statistical methods for design and analysis with applications in immunoassay and other analytical techniques. In immunoassay, concentrations of components in clinical samples are measured using antibodies.

FEBS Open Bio, EarlyView.This study investigated a novel WST‐8‐based assay for evaluating d‐Amino acid oxidase (DAO) inhibitors. We confirmed its effectiveness using known inhibitors and found that uremic toxins possess relatively weak inhibitory activity compared to existing drugs.

Scheffé-type Confidence Region for the Calibration Line
Austrian Journal of Statistics, 2016 Analyzed is the comparative calibration problem in the case when linear relationship is assumed between two considered measuring devices. The method deriving the approximate confidence region for the unknown parameters of the calibration line based on ...
