How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

We analyse and mutually compare time series of covid-19 -related data and mobility data across Belgium's 43 arrondissements (NUTS 3). In this way, we reach three conclusions. First, we could detect a decrease in mobility during high-incidence stages of the pandemic. This is expressed as a sizeable change in the average amount of time spent outside...
In this work we extend our previously developed compartmental SEIQRD model for SARS-CoV-2 in Belgium. The model is geographically stratified into eleven provinces and a telecommunication dataset provided by Belgium's biggest operator is used to incorporate interprovincial mobility. We introduce variants, seasonality, and vaccines in our model, as t...
Given that social interactions drive the spread of infectious diseases amongst humans, one anticipates that human mobility in Belgium affected the spread of COVID-19 during both 2020 "waves". Measures against this spread in turn influenced mobility patterns. In this study, we analyse and mutually compare time series of COVID-19-related data and mob...
In this report, we bring our epidemiological models in line with the additional measures taken between November 22nd, 2021, and January 28th, 2022, and reassess their impact on the fourth Belgian COVID-19 wave. A larger reduction of leisure contacts results in a faster decrease of COVID-19 hospitalizations and a lower overall burden of disease for...
In this report, we use two epidemiological models to explore the relative effects of three non-pharmaceutical interventions between November 17th, 2021, and December 24th, 2021 on the COVID-19 related hospitalizations during the fall and winter of 2021 in Belgium. Although the healthcare system will most likely not be overwhelmed by the fourth CO...
We present a compartmental extended SEIQRD metapopulation model for SARS-CoV-2 spread in Belgium. We demonstrate the robustness of the calibration procedure by calibrating the model using incrementally larger datasets and dissect the model results by computing the effective reproduction number at home, in workplaces, in schools, and during leisure...
The ability to directly detect gravitational waves has enabled us to empirically probe the nature of ultra-compact relativistic objects. Several alternatives to the black holes of classical general relativity have been proposed which do not have a horizon, in which case a newly formed object (e.g. as a result of binary merger) may emit echoes: burs...
