Food security is challenged by a growing global population and by climate change. Drought and soil salinity are considered the most important ones that inhibit crop yield and distribution. Worryingly, climate change is predicted to increase not only their frequency and severity, but also their co-occurrence,…

The thesis is about the study of shell evolution of the Hydrocenidae of the genus Georissa. This thesis started with a general overview on the evolutionary process of animals due to ecological changes.

This thesis mainly focuses on multimodal understanding and Visual Question Answering (VQA) via deep learning methods. For technical contributions, this thesis first focuses on improving multimodal fusion schemes via multi-stage vision-language interactions.

In photoactivated chemotherapy (PACT), a biologically active compound is caged by a light-cleavable protecting group.

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.

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 dissertation aims to advance understanding of amoeboid single cell migration under the influence of changing physicochemical environmental properties. The particular focus is on the relatively unknown influence of differing physical properties in the extracellular environment, such as the migratory…

De Leiden Slavery Studies Association (LSSA) is toegewijd aan het bevorderen van een beter begrip van slavernij en post-slavernij in elke periode en elk geografisch gebied.

The inverse electron demand Diels-Alder (IEDDA) pyridazine elimination emerged in 2013 as a new bioorthogonal reaction and constitutes a prime example of what is now known as dissociative bioorthogonal chemistry. The research described in this Thesis aims to develop synthetic strategies which enable…

Met sensoren op de zeebodem speuren Leidse natuurkundigen naar Neutrino’s om inzicht te krijgen in de werking van deeltjesversnellers. Dat doen zij binnen twee internationale samenwerkingsverbanden; Antares en KM3NeT. Begin mei zijn de eerste sensoren succesvol geïnstalleerd. Dat blijkt uit het licht…
