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

In onze eerdere meta-analyse (Swart et al., 2019) toonden we aan dat door het geven van feedback gericht op tekstbegrip meer van teksten geleerd wordt. Tot dusver werden de verschillen in de effecten van feedback verklaard door verschillen in timing van feedback en de hoeveelheid informatie in de feedback.…

Until the 1990s, the only known planets were those in our Solar System. Three decades later, several thousand exoplanets have been discovered orbiting stars other than the Sun, and substantial efforts have been made to explore these strange new worlds through spectroscopic analyses of their atmosphe…

Constraint multi-objective optimization with a limited budget for function evaluations is challenging. This thesis tackles this problem by proposing new optimization algorithms. These algorithms are applied on holistic ship design problems. This helps naval architects balance objectives like cost, efficiency,…

In de onderzoekslijn Geneesmiddelenonderzoek werken we voornamelijk met knaagdieren. Knaagdieren, zoals muizen, worden veel gebruikt als proefdier. Deze kleine zoogdieren zijn makkelijk te houden en planten zich snel voort.

We find ourselves in an era of transition, not just towards a more computing- and data-driven society but also away from unsustainable fossil fuels as an energy source.

The investigation into the bidirectional communication between the gut and its host is a rapidly growing area of research, attracting considerable attention for its potential to provide crucial insights into health and disease.

Humans and songbirds learn their vocalizations early in life by exposure to the vocalizations of adult conspecifics. Often, better learning outcomes are achieved with live, social, tutors than with audio-only exposure to vocalizations.

Dissolving microneedles are a subgroup of microneedle types that completely dissolve within the skin. During this dissolving process the vaccine, stored in the needle matrix, is released into the skin.

In this thesis, I targeted the orchid genus Lepanthes, one of the six genera of angiosperms that surpasses 1,000 species in the Neotropics, as a study model to investigate the evolutionary processes that promoted species diversifications.

In the early universe, the dynamics of the Higgs field can give rise to many interesting phenomena.

This thesis investigates a pharmacological challenge model induced by Toll-like receptor 7 (TLR7) activation, focusing on skin inflammation and its implications for early drug development.

The type-IV secretion system (T4SS) is a machinery able to transfer DNA and proteins between bacteria and in certain cases also to eukaryotic cells.

The focus throughout this thesis will be on gathering fundamental studies of the detailed structure and composition of the electrode/electrolyte interface effect on the rate and mechanism of key electrocatalytic reactions.

In some condensed matter systems, such as the surface of a 3D topological insulator, the electrons are effectively massless and we must necessarily use the massless Dirac equation to describe them.

Acidobacteria is a widely distributed phylum but their functional roles in ecosystem processes are still largely elusive.

The demand for neodymium-iron-boron (NdFeB) magnets is rapidly growing, while the neodymium supply chain is under pressure. Recycling can alleviate these issues. This thesis investigates the potential for deploying novel magnet recycling technologies and their environmental consequences.

Reducing greenhouse gas emissions is one of the most pressing challenges that humanity faces in the coming decades.

In today's volatile market environments, companies must be able to continuously innovate. In this context, innovation does not only refer to the development of new products or business models but often also affects the entire organization, which has to transform its structures, processes, and ways of…

This thesis applies data mining in commercial settings in the telecommunications industry.

This thesis seeks to combine two different research topics; Multi-Objective Optimization and Complex Network Analysis.

This thesis is concerned with the constitution of chiral responsive matrix assemblies that may undergo light-driven conformational changes and self-select vibrations to develop vibronic states for driving semi-classical coherent transfer with nearly 100% yield in a lossless NCAP process.

This thesis describes the role of pollution, specifically neonicotinoid insecticides, as an actor of the ongoing biodiversity decline.

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

Advanced sensing techniques require graphene with high quality and well-controlled surface chemistry.

This thesis systematically analyzes the physical-chemistry of lipid-graphene interactions with the major objective of reconciliating the variety of results reported in the literature.

Doordat markten in toenemende mate zijn geïnternationaliseerd, zijn (sub-)nationale toezichthouders ook steeds vaker internationaal actief. Binnen vormen van internationale netwerksamenwerking wisselen deze toezichthouders onderling informatie uit en onderhandelen ze over internationale standaarden…

In this thesis, I study the formation of large-scale structure and the physics of particle acceleration at large scales (~Mpc).
