A validation methodology for size and shape measurement of nanoplastics by transmission electron microscopy
TEM grid. For each material, 15 different TEM specimens are prepared and imaged on 5 different days (3 per day). For each specimen, 10 images are recorded systematically and randomly over the grid ...
Estimating the Uncertainty in Airborne Birch Pollen Modelling
temperature of birch catkins. For each input dataset, 100 randomly sampled data layers were prepared for running SILAM 100 times. For the maps, in each 1° by 1° block containing 100 grid cells (0.1° x 0.1° ...
Assessing uncertainty in airborne birch pollen modelling
season (1° × 1° map), and the ripening temperature of birch catkins—sets of 100 randomly sampled data layers were prepared for running SILAM 100 times. For each set of model input, 100 spatio-temporal maps ...
Please don't throw me in the briar patch! Empirical evidence on the role of instructional cues on eco-label usage in fish consumption decisions
ambiguous, with uncertainties regarding induced consumption shifts stemming from both deliberate information processing and less deliberate associations. This article presents findings from a randomized ...
Novel prediction models for genotoxicity based on biomarker genes in human HepaRG™ cells.
were used, but as unsupervised machine learning did not clearly distinguish between groups, the performance of two supervised machine learning algorithms, i.e., support vector machine (SVM) and random ...
Daily heart rate characteristics, allergy symptom severity and mood in adults with allergic rhinitis
hours/day). Associations between heart rate characteristics and allergy symptom severity or mood (lag 0-2) were estimated using linear mixed effects regressions, adjusted for potential confounders with a random ...
Quality control and correction method for air temperature data from a citizen science weather station network in Leuven, Belgium
intra-station (station-specific) temperature biases by means of a random forest approach. The QC method is evaluated using data from four WH2600 stations installed next to official weather stations belonging to ...

Publication Type: Scientific poster, presentation or proceeding Authors: Ingrid Pelgrims; Brecht Devleesschauwer; Stefanie Vandevijvere; E. De Clercq; Vanessa Gorasso; Van der Heyden, Johan Source: (2022) Health Topics: Santé et environnement Health and ...
Variability in the association between long-term exposure to ambient air pollution and mortality by exposure assessment method and covariate adjustment: A census-based country-wide cohort study
model using hybrid LUR exposure were 1.023 (95% CI 1.011-1.035). After including random effects HR s were 1.044 (95% CI 1.033-1.057) [NUTS-1] and 1.076 (95% CI 1.060-1.092) [NUTS-3]. Conclusion Long-term ...
Association between temperature and natural mortality in Belgium: Effect modification by individual characteristics and residential environment
pooled using a random-effect meta-analysis to describe the global association. Cold and heat effects were assessed by comparing the mortality risks corresponding to the 2.5th and 97.5th percentiles of the ...
