Unfolding potential

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

Veel kinderen leren niet op een niveau dat aansluit bij hun potentieel om te leren. Diagnostiek in de leerlingbeleiding zou daarom inzicht moeten geven in hoe een kind begeleid kan worden in het verder ontwikkelen van zijn of haar sterke kanten terwijl het tegelijkertijd handvatten biedt voor het ondersteunen…

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.

This dissertation consists of two parts, with the common theme "Exploration on and of Networks".

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 solar system was formed approximately 4.56 billion years ago. Despite the numerous theories that have been developed over the years, the formation and evolution of the solar system still remain unclear.

In this thesis, "culture" refers to the collection of subjective human traits, such as preferences an opinions, that a given, geographically bounded population has at a given moment in time.

An assessment approach that tailors to children’s instructional needs

Mechanical forces are known to play an important role in bacterial colonies. In this dissertation, we study the self-organization at various stages of growing bacterial colonies, and focus on the mechanical effects of cell growth.

Hoe beinvloed de structuur van één enkel gen de activiteit van genen die gevoelig zijn voor hormonen?

Het artikel 'Flexible updating of dynamic knowledge structures' met bijdrage van Franziska Richter van Cognitieve Psychologie is uitgebracht door Nature.

Light-Harvesting Complex II (LHCII) is responsible for light absorption and excitation energy transfer in plants and photosynthetic algae, while in high light it undergoes conformational changes by which it quenches excitations to prevent photodamage.

In the search for sustainable energy solutions, the idea of artificial photosynthesis has been proposed as an approach with which to use water and sunlight to produce hydrogen.

Developing methodes to understand the evolution of patches in natural ecosystems

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.

Scattering of light in the presence of nano-structured materials, i.e. with features in the order of the wavelength of the light or smaller, reveals details of how light interacts with matter at the nanoscale.

Making a dynamic substance stock model in order to conduct scenario analyses and make forecasts.

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

Plants and their pollinators form complex interaction networks. Within these networks, species differ widely in the number of species they interact with.

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).

A management strategy has been developed for field margins to reduce pesticide drift to non-target areas and to promote biodiversity on arable land. To this end, 3 and 6 m wide strips along the edges of winter wheat, sugar beet and potato crops have been left unsprayed with herbicides and insecticides…

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…

In previous studies at our laboratory it was demonstrated that drug exposure of HepG2 cells can lead to an altered TNFα-induced NF-κB oscillatory phenotype, concurrent with a synergistically increased sensitivity for TNFα-induced apoptosis.

Due to their central physiological roles in living organisms, retaining beta-glycosidases have been the subject of tremendous research efforts to examine their structure/function relation using numerous biophysical and biochemical approaches.

Van 2 t/m 6 juni 2014 heeft Prof. dr. Frank den Hollander 2 voordrachten verzorgd tijdens de workshop ‘Recent Models in Random Media’ op het Centre International de Rencontres Mathematiques in Marseille (CIRM), een instituut dat gedurende het hele jaar workshops voor wiskundigen organiseert.

Het onderzoek in dit proefschrift kijkt naar de rol van het locus ceuruleus - noradrenalinesysteem in verscheidene aspecten van menselijke cognitie, en de modulatie van de staat van het brein.

Bacteria often experience external challenges, such as changes in environmental conditions or attacks by bacteriophages.
