This thesis is divided into two parts. In Part I we study metastability properties of queue-based random-access protocols for wireless networks. The network is modeledas a bipartite graph whose edges represent interference constraints. In Part II we study spectra of inhomogeneous Erdős-Rényi random…

The thesis mainly contributes to the characterization of Majorana fermions as they appear in the Condensed Matter context.

In the thesis the dynamics of strategies is studied from two perspectives.In the first part of the thesis strategies are considered to be opinions present in a community.

In this thesis, dynamic testing principles were applied to examine young children's potential for learning. Our studies focused on the role of cognitive flexibility, to further increase our understanding of the cognitive processes involved in children's ability to learn from instruction and feedback,…

An assessment approach that tailors to children’s instructional needs

Can dynamic testing provide us with insight in children’s potential for learning?

BlaC is the β-lactamase of Mycobacterium tuberculosis. We show that it can recover from inhibition by clavulanic acid and that phosphate helps it do so.

The research of our group is centered around dynamical systems, functional analysis and their interplay.

If gifted children are experts in using strategies, why do they experience problems with learning? Why do they underachieve?

Dynamic nuclear polarization with paramagnetic agents can enhance nuclear magnetic resonance signals by orders of magnitude. The mechanism of enhancement depends a.o. on the magnetic resonance properties of the agents used. Electron spin relaxation times at NMR relevant magnetic field/microwave frequencies,…

The genomic DNA of every organism is organized and compacted in order to fit inside the cell. This is achieved by the joint action of numerous architectural proteins that aid in folding the genome. Genome folding is tightly interconnected with transcription, with genes in certain regions being silenced,…

Chemical reactions go hand-in-hand with an energy exchange with the environment in which they take place. Surfaces offer a variety of energy dissipation channels, constituted by the nuclear and electronic degrees of freedom of the atoms at the interface. Aiming at an improved future harvesting of energy,…

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

This research group is interested in the physics of living cells, especially their cytoskeleton dynamics under defined external stimuli.

Developing methodes to understand the evolution of patches in natural ecosystems

Schemas are knowledge structures that allow us to make efficient judgments about the world without the cost of memorizing every detail of previous experiences. It has long been known that schemas can enhance long-term memory for related information.

When a star gets too close to a supermassive black hole, it is torn apart by strong tidal forces in a tidal disruption event (TDE).

Throughout all domains of life, from bacteria and archaea to eukaryotes, genomes adopt well-organized three-dimensional structures that can change in space and time to accommodate preferred transcriptional programs for environmental adaptation, the maintenance of cellular identity and differentiation…

This volume is themed around the interdependent relationship between humans and the environment, an important topic in the work of Corrie Bakels

Hybrid zones occur where two species meet and produce offspring (hybrids). Typically, hybrids show a considerable reduction in fitness. In this thesis two hybrid zones are treated.

This functional genomics project aims at understanding the biology of the underlying mycelium differentiation and autolysis processes in much more detail.

The dissociation of CH4 into CH3 + H on a metal surface is the rate determining step in processes which produce hydrogen, such as steam reforming and catalytic partial oxidation. Ultimately, we want to study the dissociation of methane on Ni(111) and Pt(111) quantum mechanically while taking into account…

The earth has more than 7 billion inhabitants, all of whom leave behind traces of pollution. However, not all forms of pollution have the same harmful effect. Leiden scientists help determine where we should put our priorities.
