In this thesis integral points on affine del Pezzo surfaces are studied.

Het is moeilijk om de waarde en het belang van mensenrechten te ontkennen, en toch wordt hun toepassing in de context van klimaatverandering steeds meer betwist. Terwijl sommigen beweren dat het moeilijk is om de schending van mensenrechten door klimaatveranderingsprocessen vast te stellen, beweren…

The use of increasingly large and diverse datasets to guide urban climate action has implications for how, and by whom, local governments are held accountable.

Inspired by natural photosynthesis, perovskite-based photoelectrochemical (PEC) systems are being developed for artificial photosynthesis, aiming to enhance solar-to-hydrogen conversion for green energy.

This thesis consists of three chapters. Each chapter is on a different subject. However, all three chapters address issues that arise in counting arithmetically interesting objects.

In this thesis, we explore a Hochschild homology and cohomology-like notion for logarithmic schemes.

The aim of this thesis is to explore the use of Bioorthogonal Antigens to study the cross-presentation pathway.

We show that Kirchhoff ’s law of conservation holds for non-commutative graph flows if and only if the graph is planar. We generalize the theory of (Euclidean) lattices to infinite dimension and consider the ring of algebraic integers as such a lattice.

The first steps are made in personalised cancer vaccination strategies, which aim to induce a more specific immune response with fewer side effects. The activation of cytotoxic T cells is crucial for an effective immune response.

Glucocorticoids are potent anti-inflammatory drugs widely used clinically to treat various inflammatory and immune conditions. However, two main clinical problems limit their use. GCs trigger severe side effects and they induce acquired glucocorticoid resistance, especially during chronic systemic treatment…

Modeling and analysis of cyber-physical systems are still challenging. One reason is that cyber-physical systems involve many different parts (cyber or physical), of different nature (discrete or continuous), and in constant interaction via sensing and actuating.
