Assessing particle count in electron microscopy measurements of nanomaterials to support regulatory guidance
Upon combining the precision uncertainty related to particle numberwith uncertainties from other sources, such as sample preparation, calibration and trueness, wereach an optimal particle count above ...
Simultaneous quantification of Ibuprofen and Paracetamol in combined tablet formulations by UV–VIS spectrophotometry and chemometric modelling
Different sources of variability, not related with concentration differences between the samples, were incorporated into the calibration data in order to obtain stable models which wouldn’t be affected from ...
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 ...
