The plant hormone auxin plays a central role in the growth and development of plants. Auxin acts in a concentration dependent manner and polar cell-to-cell transport of this hormone determines its distribution in the tissues of plants. This polar auxin transport is mediated by several families of auxin…

The research group Science Communication and Society aims to understand how science communication works to improve the interaction between science and society. Central themes are ‘Bridging the gap between experts and the general public’ and ‘Evaluating Science Communication’.

Reactions and reaction times in cognitive tasks.

Nowadays, it is well known that hydrogen and helium (and small traces of lithium and beryllium) were created shortly after the Big Bang, while the heavier elements are created in the cores of stars at different evolutionary stages. When these stars explode as supernovae, they expel metals synthesised…

Anthropogenic noise negatively affects wildlife in a wide range of taxonomic groups.

Experience, Narrative, and Criticism in Ancient Greece pursues a new approach to ancient Greek narrative beyond the taxonomies of structuralist narratologies.

Classical statistical methods, such as p-values, are difficult for researchers to apply correctly. They for example do not allow drawing conclusions from a study early, or for extending a study with extra research groups that want to make their data available later.

In this thesis, we extend the concept of null models as canonical ensembles of multi-graphs with given constraints and present new metrics able to characterize real-world layered systems based on their correlation patterns.

The work described in this dissertation contributes to a better mechanistic understanding of nanoparticles in vivo. To achieve that goal, we used the zebrafish as a highly predictive pre-screening model of nanoparticles.

In this opinion article published in World Development, the authors present five research and policy priorities. While it is clear that ‘pluriversal’ designs need to guide the way forward (Kothari et al 2019), defining a set of key pillars can provide direction and purpose across this pluriversality.…

This dissertation focuses on questions about the purposes of education and what it means to be educated. These questions are relevant across time, as the answers to these questions are always to some extent related to contemporary society.

Proteases degrade matrix molecules in the atherosclerotic plaque, thereby reducing atherosclerotic plaque stability. Mast cells, that contain proteases such as tryptase and chymase, have been identified at the site of rupture in specimens of human coronary arteries and their number in the plaque was…

Our current research focusses on the exploration of the Universe using the neutrino. This neutral, almost massless and only weakly interacting particle can open a window to the distant Universe and also dense regions from which photons cannot escape.

Technological advances have an impact on our daily lives. They have also been employed by governments to manage border security, especially at controversial border crossings. Fences, heat sensors, heat cameras, drones and other hi-tech equipment that are currently being tested collectively produce a…

On Tuesday 14 January 2025 Milan Ismangil successfully defended a doctoral thesis and graduated.

SDN (Software-Defined Networking) represents a revolutionary approach to network architecture that enables the dynamic and flexible management of network resources through software-based control. This dissertation introduces the idea of SDN and its southbound protocol OpenFlow, then presents the formal…

Four years of protracted negotiations and bitter warfare passed between the declaration of Indonesian independence on 17 August, 1945, and the official transfer of sovereignty on 27 December, 1949.

Bacterial chemosensory arrays are protein assemblies that are the key structural and functional component for motile bacteria to sense their internal or environmental chemical signals.

What is the current relevance of the ethics of counterterrorism and what is the added value of ethics support within the practice of counterterrorism?

Science and education can really flourish in an environment where everyone can be themselves and where there is room for different perspectives that bring people together from different ethnicities, genders, sexual orientations, health, religion, age and socio-economic background.
