This thesis presents the systematics, epidermal defense, and bioprospecting of wild orchids.

Astronomical observations of cold regions in the universe show a rich inventory of ices. Part of these ices may end up on planets like our own, but in that journey they will be exposed to considerable amounts of radiation.

We developed the bitterling as a unique, well-studied model organism in the area of the evolutionary ecology of brood parasitism. The bitterling-mussel relationship, interspecific mussel host preference, and mussel gill structure are studied in detail, to help understand the developmental adaptation…

Lysosomal storage disorders (LSDs) are a group of orphan diseases characterized by lysosomal dysfunction or impaired lysosomal catabolism and affect collectively about 1 in 5000 live births.

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

Op 13 januari 2022 verdedigde Pie Habimana het proefschrift 'Harmful Tax Competition in the East African Community'. Het promotieonderzoek is begeleid door prof.dr. H. Vording en prof.dr. S.C.W. Douma (UvA).

Statistical considerations guide the design and implementation of the experiments that scientists perform. For instance, in a clinical trial about a the efficacy of a treatment, its effect in a certain minimum amount of patients has to be observed in order to make confident assertions about the efficacy…

When observing star-forming galaxies, we are not only seeing stellar light, but we also see how this interacts with galactic gas and dust. This thesis contains studies of the stellar, nebular and dust properties of low mass star-forming galaxies.

Multicopper oxidase, laccase, can efficiently reduce oxygen to water and are mostly used in the enzymatic biofuel cells.

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-…

Beleef en ervaar de materiële aspecten van middeleeuwse manuscripten, geannoteerde boeken, prenten, tekeningen en fotoalbums tijdens een van de vele activiteiten.

Protein–protein complexes are formed via transient states called encounter complexes that greatly influence the formation of the stereospecific complex.

The idea of citizens and public professionals collaborating to provide public services has widely spread in several countries around the globe. Co-production is often presented as the go-to solution for challenges like a legitimacy crisis of both the government and the market, and financial concerns.…

The main focus of the thesis is the discovery and development of novel inhibitors of bacterial metallo-β-lactamases (MBLs).

An important part of the SCS specialisation is the internship period. Students will get the opportunity to get to know the field and to apply what they have learned during the courses.

Viral hemorrhagic fever (VHF) is a group of acute diseases caused by highly infectious viruses including Ebola, Lassa, Dengue viruses. Its high mortality rate poses high risk to public health, however, studies on VHF have been hampered due to the non-availability of proper models and incomplete knowledge…

The overarching goal of this thesis is to set the foundations, but also make the first essential steps towards establishing a comprehensive, mesoscopic, hydrodynamic theory of epithelial tissues. The stage is set by an exhaustive study of topological defects in passive p-atic liquid crystals, singularities…

In this thesis, a system pharmacology approach, integrating metabolomics, pharmacology and chemical biology, was applied to understand and modulate the endocannabinoid system across different model systems (cells, zebrafish, mice and humans).

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…

This thesis considers multi-prover commitment schemes whose security is based on restrictions on the communication between the provers.

There are many interpretations of quantum mechanics, and ultimately experiments are needed to verify or falsify these interpretations.

The recently introduced nature-originated deep eutectic solvents, so-called natural deep eutectic solvents (NADES) are considered as truly green solvents, which composed of natural ingredients found abundantly in organisms.

This thesis is dedicated to the exploration of the primordial dark ages: unknown physics during the earliest stages of the Universe’s expansion that have not yet been directly probed by observations. Cosmic inflation is a burst of exponential expansion of space after the “Big Bang”.

Why do black holes emit thermal radiation? And how does a closed quantum system thermalize?

In films kunnen de meest wonderlijke acties plaatsvinden. Maar zijn die acties in de 'echte' wereld ook mogelijk? En in hoeverre houden filmmakers ons voor de gek? Tijdens het Leiden International Film Festival komen film en wetenschap samen.

This thesis investigates the application of deep learning techniques in image analysis across various domains, focusing on four main themes: feature extraction, classification, segmentation, and integration, demonstrating the transformative potential of these technologies.

My PhD project studies how the temporally sequential Hox gene expression is regulated during head-tail patterning of the frog embryo.

Om de juiste klinische beslissingen te nemen of effectieve diagnostische testen en behandelingen te kunnen ontwikkelen, is het belangrijk om de onderliggende mechanismen van een aandoening of een bepaald gedrag te begrijpen.

Tussen 1683 en 1795 werd Suriname bestuurd door de Sociëteit van Suriname, een samenwerkingsverband tussen het stadsbestuur van Amsterdam, de West-Indische Compagnie en de familie Van Aerssen van Sommelsdyck. Terwijl de hoogtijdagen van de Gouden Eeuw al voorbij waren bloeide Suriname gedurende het…

Large parts of the research described in this Thesis aims at the development of oligopeptide-masked toxins and their in situ immunoproteasome-mediated activation.

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.
