Potential impact fractions of body mass index reductions on the non-communicable disease burden in Belgium using G-computation

address. Self-reported BMI and diabetes were corrected based on information from the 2018 Belgian health examination survey and a random-forest multiple imputation process. A G-computation approach was used ...

COMBINATION OF CHEMOMETRICS AND MULTIDIMENSIONAL FINGERPRINTING FOR DETECTION OF REGULATED PLANTS IN PLANT FOOD SUPPLEMENTS

corrected for time shifts using correlation optimized warping and further pretreated using classical techniques like signal noise variate, autoscaling and derivatives), before being subjected to partial least ...

Spectroscopic approaches for conformity analysis of e-liquids

modelling. Next to baseline correction, classical preprocessing techniques like standard normal variate (SNV), derivatives and scaling were explored. In a first step, supervised modelling, using partial least ...
