UNLABELLED Both the standardized uptake value ratio (SUVR) and the Logan plot result in biased distribution volume ratios (DVRs) in ligand-receptor dynamic PET studies. The objective of this study was to use a recently developed relative equilibrium-based graphical (RE) plot method to improve and simplify the 2 commonly used methods for quantification of (11)C-Pittsburgh compound B ((11)C-PiB) ...

The capability of the dimensions measurement by ten appraisers of ten samples for Charpy Vnotch pendulum impact test was evaluated by Youden plot, analysis of measurement uncertainties, Measurement Systems Analysis (MSA), %P/T, Z-score, Mandel’s statistics and ttest. The group of “better” appraisers given by Youden plot was validated by majority of other methods.

spectral data from E. coli, S. aureus and P. aeruginosa infected C57BL/6 wild-type mice, showing the separation between samples along the type of infection (Fig.1A) and scores plot of the metabolite concentrations found in TLR4 deficient mice with LPS treatment and E. coli infection (Fig.1B). Two components encapsulate 82 % (A) and 90 % (B) of the interclass variation. Fig.2: The coefficient pl...

1. Time domain summary statistics and frequency domain parameters can be used to measure heart rate variability. More recently, qualitative methods including the Poincaré plot have been used to evaluate heart rate variability. The aim of this study was to validate a novel method of quantitative analysis of the Poincaré plot using conventional statistical techniques. 2. Beat-to-beat heart rate v...

Studying on spatial and temporal variation in soil organic carbon (SOC) is of great importance because of global environmental concerns. Tillage-induced soil erosion is one of the major processes affecting the redistribution of SOC in fields. However, few direct measurements have been made to investigate the dynamic process of SOC under intensive tillage in the field. Our objective was to test ...
