Unsupervised machine/deep learning mapping (clustering) for single/multi-source remote sensing data University of Antwerp
In recent years, there has been an explosive growth in remotely sensed (RS) data usage in geoscience and Earth observation applications. The recent technical advancements allow users to acquire various types of rich information. A quintessential example of RS data is hyperspectral imagery. A hyperspectral image (HSI) provides rich spectral data over a wide range of the electromagnetic spectrum. Such information enables users to identify, track ...
Specialization in stuttering and cluttering : a European perspective Ghent University
Explaining clusterings of process instances KU Leuven
This paper presents a technique that aims to increase human understanding of trace clustering solutions. The clustering techniques under scrutiny stem from the process mining domain, where the clustering of process instances is deemed a useful technique to analyse process data with a large variety of behaviour. Until now, the most often used method to inspect clustering solutions in this domain is visual inspection of the clustering results. ...
MultiClust special issue on discovering, summarizing and using multiple clusterings University of Antwerp
Trial and terror : countering violent extremism and promoting disengagement in Belgium Ghent University
Efforts to promote disengagement from violent extremism have become a key ingredient in many counter-terrorism policies around the world. Deradicalisation and disengagement initiatives can also vary considerably from country to country. The following article contributes to the growing literature on countering violent extremism (CVE) by delineating the Belgian CVE landscape. Drawing on 50 semi-structured interviews with frontline practitioners ...
Suppressing hydrogen blistering in a magnesium-rich healable laser powder bed fusion aluminum alloy analyzed by in-situ high resolution techniques University of Antwerp
Hydrogen blistering, i.e. precipitation of supersaturated hydrogen at elevated temperatures, increases porosity during heat treatments in 4xxx series Al alloys manufactured by laser powder bed fusion (LPBF), as demonstrated by 3D X-ray nano-imaging in AlSi12. This paper proposes the design of a healable Al alloy to suppress hydrogen blistering and improve the damage management. The strategy consists of solute atoms diffusing towards nano-voids ...
System Xc- inhibition blocks bone marrow-multiple myeloma exosomal crosstalk, thereby countering bortezomib resistance Vrije Universiteit Brussel
Multiple myeloma (MM) cells derive proliferative signals from the bone marrow (BM) microenvironment via exosomal crosstalk. Therapeutic strategies targeting this crosstalk are still lacking. Bortezomib resistance in MM cells is linked to elevated expression of xCT (the subunit of system Xc-). Extracellular glutamate released by system Xc- can bind to glutamate metabotropic receptor (GRM) 3, thereby upregulating Rab27-dependent vesicular ...
