A validation methodology for size and shape measurement of nanoplastics by transmission electron microscopy
the uncertainty related to repeatability (within day) and uncertainty related to day-to-day variations (between day) obtained by ANOVA analysis. Adding the uncertainty related to calibration of the ...
Full Characterisation of Heroin Samples Using Infrared Spectroscopy and Multivariate Calibration
environment of user centra, could be a supplementary service in the context of harm reduction. Infrared spectroscopy hyphenated with multivariate calibration could be a valuable asset in this context, and ...
Complete genome reconstruction of the global and European regional dispersal history of the lumpy skin disease virus.
global publicly available genomes. We formally evaluate the past occurrence of recombination events as well as the temporal signal that is required for calibrating molecular clock models and subsequently ...

SCORE2-Diabetes: 10-year cardiovascular risk estimation in type 2 diabetes in Europe.
regions. External validation included 217 036 further individuals (38 602 CVD events), and showed good discrimination, and improvement over SCORE2 (C-index change from 0.009 to 0.031). Regional calibration ...
Using random-forest multiple imputation to address bias of self-reported anthropometric measures, hypertension and hypercholesterolemia in the Belgian health interview survey
Belgian health interview survey (BHIS) older than 18 years, of which 1184 participated in the 2018 Belgian health examination survey (BELHES), were included in the analysis. Regression calibration was ...
Towards a Better Quantification of Cyanotoxins in Fruits and Vegetables: Validation and Application of an UHPLC-MS/MS-Based Method on Belgian Products
The validation of a UHPLC- MS / MS method in the strawberry matrix is novel. Matrix effects are observed in all three matrices. Our methodology uses matrix-matched calibration curves to compensate for ...
Towards standardisation of automatic pollen and fungal spore monitoring: best practises and guidelines
monitoring, including a set of guidelines and recommendations. It covers issues relevant to developing an automatic monitoring network, from the instrument design and calibration through algorithm development ...
Relative response factors and multiple regression models in liquid chromatography to quantify low-dosed components using alternative standards-proof of concept: total Δ9-THC content in cannabis flowers using CBD as reference.
a one-point calibration or a calibration line, prepared using a reference standard of the compound(s) of interest. However, in some cases, adequate reference standards may be very expensive, rare to obtain, or ...
Dependence-Robust Confidence Intervals for Capture–Recapture Surveys
bounds on pairwise capture probabilities using two methods: test inversion bootstrap confidence intervals and profile likelihood confidence intervals. Simulation results demonstrate well-calibrated ...
