Enzymes are innately sensitive to changes in the amino acid sequence, which largely constrains their evolutionary potential, i.e., evolvability. This evolutionary burden can be alleviated in the presence of stabilizing mutations, which increase the buffering capacity of enzymes to tolerate mutations…

This thesis discusses several questions regarding the double ramification cycle as a Chow class on the moduli space of stable n-pointed genus g curves using tools from so-called logarithmic geometry.

Autophagy is a fundamental degradative process, maintaining cellular homeostasis and functions in host defense against intracellular pathogens, including mycobacteria and Salmonella.

Inflammatory skin diseases such as psoriasis and atopic dermatitis can severely impact both the physical and social aspect of a patient’s life. Aberrant inflammatory responses are thought to be a major causative factor in these disorders, but an abundance of different factors contribute to the development…

The studies presented in the work show the potential of the integrative use of biophysical data in defining the structural basis of protein interactions.

For each living organism health is ensured by correct functioning of its cells. Cells therefore have elaborate methods for regulation of their proteins.

This course explains the functions of each international court and tribunal in The Hague. On the basis of cases and interviews with judges and lawyers, this course explores the role of these courts and tribunals and their potential to contribute to global justice.

The aim of this thesis is to present novel techniques for proving cryptographic schemes secure against quantum adversaries. Most results are within the context of an idealized model called the ‘quantum random-oracle model’.

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…

Beneficial plant-associated microbiota, particularly those inhabiting the rhizosphere, contribute substantially to plant health through pathogen suppression, stimulation of plant defence responses, and enhanced nutrient acquisition.

Programma's die de symptomen van sociale angst bij kinderen willen verminderen, omvatten doorgaans meerdere onderdelen, zoals blootstelling en mentale herstructurering. Het is onbekend of afzonderlijke onderdelen positieve effecten opleveren bij kinderen of dat een combinatie van onderdelen nodig is…

Human vocal communication and music perception represent advanced cognitive skills, seemingly innate and universal. These faculties encompass a range of perceptual and cognitive abilities. Cross-species research sheds light on the origins of musicality by investigating whether these traits are shared…

Onderzoekers werken al eeuwen aan een atlas van het brein. Maar zelfs in 2017 zijn sommige hersenstructuren nog niet in kaart gebracht, met name in de hersenstam. In dit paper hebben we de test-hertest betrouwbaarheid gemeten van de enige MRI-scan die onderzoekers in staat stelt om de locus ceruleus,…
