The theoretical explanation of cosmic acceleration is nowadays one of the biggest puzzles in cosmology.

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.

In times of hardships or crisis, local people know how to deal with it using their resourcefulness. Although efforts are sometimes made by the government to help them, they are fully aware that community support is at least equally important.

In dit project worden reisverslagen over Nederlands-Indië bestudeerd die zijn geschreven tussen 1800 en het einde van de Tweede Wereldoorlog. Door zowel Nederlandse reisteksten als inheemse reisteksten in het Javaans en Maleis te analyseren, wordt een nieuw, tweestemmig perspectief op (de geschiedschrijving…

This thesis describes a study from both a theoreticaL and an experimental point of view.

In the first part, we introduce a new condition, called toric-additivity, on a family of abelian varieties degenerating to a semi-abelian scheme over a normal crossing divisor.

The sequence-dependence of biomolecular interactions involving nucleic acids and proteins is essential for numerous processes inside the cell. Insights into the underlying molecular mechanisms have been obtained using various biochemical and biophysical methods on two different levels — bulk and sin…

The lipid membrane is a basic structural component of all living cells. Embedded in this nanometer-thin barrier, membrane proteins shape the membrane and at the same time respond to the shape of the membrane.

Tracing the evolution of the molecular gas content in galaxies is critical for a complete understanding of galaxy formation and evolution, as it provides the direct fuel for star formation. Studies of high-redshift (z>1) molecular gas reservoirs, most commonly traced by carbon monoxide (CO), have seen…

In this thesis we study the landscape of gravitational models which modify GR by introducing an additional scalar degree of freedom (d.o.f.) to source Cosmic Acceleration.

The aim of the research presented in this thesis was to develop new methods forchallenging systems in liquid-state NMR using paramagnetic effects generated by thetwo-armed probe CLaNP-5.

Metals surfaces form a group of effective catalysts for the reaction of small molecules such as hydrogen (H2).

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…

The overarching clinical aim of this thesis was to improve pharmacological pain management by characterizing the pharmacodynamics of analgesics. This promotion has been awarded the predicate cum laude.

In surface science there is great effort to move from studying simple, flat model surfaces in vacuum to investigating more complex model catalysts in gas environments (in situ). This thesis gives three examples of such studies using microscopy and spectroscopy.

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.

Artificial intelligence algorithms govern in subtle, yet fundamental ways, the way we live and are transforming our societies. The promise of efficient, low‐cost or ‘neutral’ solutions harnessing the potential of big data has led public bodies to adopt algorithmic systems in the provision of public…

Aan de opleidingen van het Centre for Professional Learning op het gebied van Terrorisme, Recht en Veiligheid zijn verschillende (research) fellows verbonden. De fellows geven advies over de inhoud van het curriculum en de verbinding tussen wetenschap en praktijk.

Mechanical metamaterials are man-made materials which derive their unusual properties from their structure rather than their composition.

Het LUC Fonds maakt deel uit van het Leids Universiteits Fonds (LUF). Het Fonds wordt beheerd door het administratieve personeel van LUC en staat onder toezicht van een Bestedingscommissie, die bestaat uit medewerkers en alumni.
