Small weight code words arising from the incidence of points and hyperplanes in PG (n,q) Ghent University Vrije Universiteit Brussel
Minimal codewords arising from the incidence of points and hyperplanes in projective spaces Ghent University
Comparative incidence rates of mild adverse effects to transcranial magnetic stimulation Ghent University
Objectives: Past research has largely neglected to investigate mild adverse effects (MAEs) to transcranial magnetic stimulation (TMS), including headache and nausea. Here we explored the relationship between MAEs, participant characteristics (age and gender) and protocol parameters, including mode of application, coil geometry, stimulated brain region, TMS frequency, TMS intensity, and active vs. sham stimulation. Methods: Data from 1270 ...

On epidemiology of fractures and variation with age and ethnicity Hasselt University
We recently demonstrated differences in fracture incidence by ethnicity in the UK population using the Clinical Practice Research Datalink (CPRD) [1]. In their letter, Harper et al. [2] draw attention to the differential age structure of the UK population by ethnicity, and suggest that the lower incidence of fractures in Asian adults over 50 years might reflect the lower proportion of very elderly individuals within this demographic compared ...
General Galois geometries Ghent University
This book is the second edition of the third and last volume of a treatise on projective spaces over a finite field, also known as Galois geometries. This volume completes the trilogy comprised of plane case (first volume) and three dimensions (second volume). This revised edition includes much updating and new material. It is a mostly self-contained study of classical varieties over a finite field, related incidence structures and particular ...
The isomorphism problem for linear representations and their graphs Vrije Universiteit Brussel
In this paper, we study the isomorphism problem for {\em linear representations}. A linear representation $T_n^*(\K)$ of a point set $\K$ is a point-line geometry, embedded in a projective space $\PG(n+1,q)$, where $\K$ is contained in a hyperplane. We put constraints on $\K$ which ensure that every automorphism of $T_n^*(\K)$ is induced by a collineation of the ambient projective space. This allows us to show that, under certain conditions, two ...
