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

Polycyclic aromatic hydrocarbons (PAHs) are the most abundant class of organic compounds in space. The PAH field evolves from the constant interaction between experimentalists, theorists, modellers and observers. While laboratory research and quantum chemical calculations together set up the molecular…

Quantum computing is an emerging technology, which holds the potential to simulate complex quantum systems beyond the reach of classical numerical methods.Despite recent formidable advancements in quantum hardware, constructing a quantum computer capable of performing useful calculations remains challenging.In…

Mycoheterotrophy is a particular mode of life in which plants obtain carbohydrates from their associated fungal partners, instead of by using photosynthesis.

Self-assembly is an abundant process in nature and is vital to many processes in living organisms.

Clinical development of drugs for central nervous system (CNS) disorders has been particularly challenging and still suffers from high attrition rates.

Sustainable energy from wind and solar is most readily available near the sea.

Optimization tasks in practice have multifaceted challenges as they are often black box, subject to multiple equality and inequality constraints and expensive to evaluate.

The radio sky harbours both galactic and extragalactic sources of arcminute- to degree-scale emission of various physical origins. To discover extragalactic diffuse emission in the Cosmic Web beyond galaxy clusters, one must image low–surface brightness structures amidst a sea of brighter compact fore-…

In this thesis we will explore the use of fuzzy systems theory for applications in bioinformatics.

The way organisms develop from the initial single-cellular state to a complex final assembly like the human body, and how the final body is maintained throughout life, is one of the greatest mysteries and it’s understanding one of the biggest scientific challenges.

Electron microscopy has become an extremely important techniquein a wide variety of elds.

The high velocity tail of the total velocity distribution of stars provides essential insight into fundamental properties of the Galaxy.

A dense region of a gaseous and dusty cloud collapses to form a protostar surrounded by a disk and an envelope. This thesis uses both observations and models to study physical and chemical conditions of these protostellar systems which are likely where planets start to form.

Lysosomal acid glucosylceramidase (GBA1) is a lysosomal enzyme that degrades glucolipids with its main substrate being glucosylceramide (GlcCer). Defects in the GBA1 gene lead to glycosphingolipidosis Gaucher disease (GD), in which the hydrolysis of GlcCer is impaired and therefore, it accumulates in…

De scriptie is een belangrijke mijlpaal voor masterstudenten die afstuderen in de Politicologie. Daarmee laten zij zien dat zij in staat zijn om zelfstandig onderzoek te doen en maatschappelijke vraagstukken grondig en objectief kunnen analyseren. Daar komt veel bij kijken: uren in de collegebanken,…

We willen allemaal een wereld waarin individuen veilig zijn, conflicten vreedzaam worden beslecht en rekening wordt gehouden met toekomstige generaties. Juristen van de Universiteit Leiden onderzoeken in hoeverre het internationaal publiekrecht voorziet in de behoeftes van een geglobaliseerde samenleving.…

The research in this dissertation aims to optimise blood donation processes in the framework of the Dutch national blood bank Sanquin. The primary health risk for blood donors is iron deficiency, which is evaluated based on donors' hemoglobin and ferritin levels.

This thesis describes how complex and real-world relevant analytical solutions can be found starting from a simple Nagumo problem posed on one or two-dimensional lattices.

The work described in this Thesis is focused on the assembly of oligosaccharide fragments derived from a fungal polysaccharide, galactosaminogalactan (GAG) and fragments of the exopolysaccharide Pel, generated by Pseudomonas aeruginosa.

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 thesis describes the antimicrobial discovery strategy developed in our group, the den Hertog Group at the Hubrecht Institute. It includes a cultivation-based screening approach for novel antimicrobial agents from the source of fungi, and a bacterial time-lapse imaging approach for antimicrobial…

We investigate how radiation pressure can be used to influence the mechanical motion of a micro-mirror suspended from springs.

In this thesis we study quantum transport phenomena on the nanometer scale, in two classes of materials: topological insulators with induced superconductivity and graphene superlattices.

Freshwater biodiversity has been threatened by eutrophication due to excessive nutrients in the environment. Releasing the freshwater species from such pressures requires efforts from industry and manufacturers to avoid emissions to vulnerable and high-risk regions.

This multidisciplinary minor provides students with knowledge on how and why humans became the way they are. The minor focuses on the evolution of the species Homo sapiens from other hominin lineages and animal ancestors, and on the various factors shaping this process. Not only is human evolution of…

Bedreigde talen kunnen voortleven als ze goed worden geleerd aan nieuwe sprekers, zoals mensen met een migratieachtergrond. Dit stelt bijzonder hoogleraar Felix Ameka in zijn oratie op 30 september. Nederlanders kunnen daaraan bijdragen door zich minder ‘beleefd’ op te stellen richting mensen van wie…
