More than half of the patients treated for cancer receive external Beam Radiation Therapy (EBRT) during the course of their disease. EBRT is typically characterized by highly standardized protocols and relies on the precise daily delivery of high energy X-rays combined with volumetric imaging tools. In order to further improve cancer care in Belgium, the UZ Leuven and the Cliniques Universitaires Saint-Luc have recently built in partnership ...
There is a growing trend in the space industry to use small-scale (< 50kg) spacecraft. These satellites are much cheaper to build and launch than traditional spacecraft (> 500kg) but thanks to the miniaturisation of electronic and mechanical components they can be used for high-quality missions. The downside of these spacecraft is that their reduced launch volume can not directly accommodate a large optical system and the reduced light ...
Fibreoptic networks are the driving system behind increasing data-rates. Optical communication has promising prospects, is continuously evolving and is the choice for integration in future infrastructures. However, such networks are costly to implement due to the laser and photodetector components that are needed to convert the optical and electrical signals to each other. These external components are currently developed through less common ...
Lately there have been impressive improvements in the fields of Machine Intellegence and AI. The problem with these recent models is that they are not able to adapt or evolve. This is problematic when the model has to learn a new category or label, a new action or behavior or something else. The only way a static model can adapt and learn something new is by retraining on all previous data and the new data combined. This means that all ...
Chronic Rhinosinusitis (CRS) represents a very frequent disease with an enormous impact on quality of life and work loss in our society. So far, its pathophysiology remains rather unclear and nothing is known about the role of immunoglobulin A (IgA), a protective antibody that seems to be dysfunctional in these patients. To study the role of IgA and its polymeric Ig receptor (pIgR) in vivo, we will test 3 models of different CRS phenotypes ...
Bij gemetastaseerd melanoom blijft, ondanks de recente doorbraken in gerichte therapie en Immune Checkpoint Blockade (ICB), het 5-jaars overlevingspercentage rond de 54%. Dit is in ieder geval gedeeltelijk te wijten aan de hoge plasticiteit van melanoomcellen en hun vermogen om snel te schakelen tussen verschillende geneesmiddeltolerante rangen bij blootstelling aan therapie, waardoor ze aan deze dreiging kunnen ontsnappen. ...
Many electricity generation systems are undergoing drastic changes, through rapidly increasing shares of intermittent renewable energy sources (RES) like wind and solar photovoltaics. Models are often used to address the corresponding challenges (technical, economic, policy), by analyzing system operation and planning. In this PhD, we aim to strengthen the link between generation and grid planning. During the optimization of the grid design, ...
Analysis of ions using reversed-phase liquid chromatography is not straightforward. Certainly for the analysis of elements such as sodium, potassium, calcium, magnesium,… other techniques have been applied, like atomic spectroscopic methods, and to a lesser extent capillary electrophoresis. However, these have several drawbacks and ion chromatography coupled with conductivity detection became the method of choice. The detection signal is ...
