This thesis describes how complex and real-world relevant analytical solutions can be found starting from a simple Nagumo problem posed on one or two-dimensional lattices.

In this thesis we study bistable reaction-diffusion equations on lattice domains.

This dissertation studies the Asymptotics of Bayesian nonparametric inference for Gaussian linear models.

In this thesis, we study travelling waves in stochastic reaction-diffusion equations. We extend techniques from the deterministic theory for travelling waves to apply to the stochastic version, which allows us to compute the stochastic wave speed and shape, and draw conclusions on the stability of the…

Why do black holes emit thermal radiation? And how does a closed quantum system thermalize?

One of the effects of climate change is the phenomenon of desertification, a process that occurs in semi-arid and arid areas and causes land degradation as well as vegetation loss. Due to the lack of resources, vegetation self-organizes to sustain itself by forming large-scale spatial patterns.

Immunotherapies for cancer are an emerging class of therapeutic strategies which aim to treat cancer via augmentation of the immune system.

Epithelial-mesenchymal plasticity (EMP) and tumor cell migration play an important role in cancer progression, and an improved understanding of the mechanisms underlying these concepts is essential for developing new targeted approaches.

We consider the propagation of electrical signals through nerve fibres.

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.

The research of the Applied Mathematics cluster is concerned with such diverse topics as dynamical systems, representation theory, differential equations and pattern recognition.

This PhD thesis concerns the topic of arithmetic geometry. We address three different questions and each of the questions in some way is about counting how big some set is or can be.

Inverse problems are problems where we want to estimate the values of certain parameters of a system given observations of the system. Such problems occur in several areas of science and engineering. Inverse problems are often ill-posed, which means that the observations of the system do not uniquely…

The Copenhagen interpretation of quantum mechanics states that a measurement collapses a wavefunction onto an eigenstate of the corresponding measurement operator.

Twee radiotelescopen hebben een aantal opmerkelijke groepen mensen bijeengebracht in het Amerikaanse Green Bank. In het bezoekerscentrum van de Oude Sterrewacht is een nieuwe fototentoonstelling geopend over een afgelegen gemeenschap in Green Bank, West Virginia. Wegens de coronacrisis is de Sterrewacht…

Het natuurkunde-instituut LION heeft een schilderij gekocht van natuurkundige Gregory Horndeski, die in 1974 een veelgeprezen artikel over de zwaartekracht schreef. Pas na 35 jaar, toen Horndeski allang kunstenaar was, werd het een hit onder kosmologen.
