This thesis investigates how galaxies form and what diversifies the evolutionary histories of galaxies.

Artin L-functions associated to continuous representations of the absolute Galois group G_K of a global field K capture a lot of information about G_K as well as arithmetic properties of K.

Hot astrophysical plasma is ubiquitous in the Universe, from comets in our Solar system to the largest scale structures -- the cosmic web filaments. These hot plasmas, with the temperature of a few millions of degrees, are often observed in the X-ray wavelength range.

A large diversity of exoplanetary systems has been found, but it is still unclear what drives this diversity.

Heart failure is a major health care problem with high mortality.

The study of orchid flowers, fruits, and inflorescences is crucial due to the remarkable diversity of orchid species and their unique adaptations to pollinators and seed dispersers. However, our understanding of the evolution and development of these organs within the orchid family remains limited.

Large carnivores and humans, along with their livestock, have co-existed for thousands of years. However, human population growth and an increase in economic activities are modifying the landscape for large carnivores and their prey.

A P300-based Brain Computer Interface character speller, also known as P300 speller, has been an important communication pathway, under extensive research, for people who lose motor ability, such as patients with Amyotrophic Lateral Sclerosis or spinal-cord injury because a P300 speller allows human-beings…

The applications of studying the early development of insects range from agriculture to material science.

The glycosylation reaction is a pivotal reaction in creating new and complex oligosaccharides.

Developing robust algorithms and theory for establishing cause-effect relationships from observational data that scale up to large data sets

I have studied the hot, diffuse gas around and between galaxies. Specifically, I have used the EAGLE numerical simulations of galaxy formation to predict the properties of this gas, and I have used those properties to predict specific observables: soft X-ray absorption and emission lines.

My PhD thesis investigates the ecological significance of resistance against drought-induced air bubble formation inside the water conduits of plants (embolism), and the plasticity and functional aspects of stem anatomical traits in woody and herbaceous species.

Op 11 november 2021 verdedigde Evelien Campfens het proefschrift 'Cross-border Claims to Cultural Objects'. Het promotieonderzoek is begeleid door prof.dr. N.J. Schrijver en prof.dr. W.J. Veraart (VU Amsterdam).

For centuries astronomers studied the Universe by collecting light. Nowadays, we are living in times of great technological advancements, which allow us to explore our Universe in a new way - though gravitational wave radiation.

Women Writing Mexico (WWM) is a network of women and men concerned with the human rights crisis in Mexico and more specifically, with the impact of structural forms of poverty, everyday violence, and discrimination based on gender, race, social class, and ethnicity, that particularly have an impact…

Fungal food spoilage often starts with a contamination with spores. Experimental data strongly indicate the existence of subpopulations of spores with different levels of resistance to preservation methods.

Wetland plants are distinguished from plants of other terrestrial ecosystems by their adaptations to specific habitat stresses, including waterlogged and flooding and the subsequent abundance of phytotoxic compounds.

Cryogenic electron microscopy (cryo-EM) is a powerful technique used to visualize the inside of cells and to study specific protein complexes. Within this thesis, I describe the use of various cryo-EM techniques to gain insight into the structural changes of the human pathogen, Vibrio cholerae, as it…

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.

Protein–protein complexes are formed via transient states called encounter complexes that greatly influence the formation of the stereospecific complex.
