Even though more than 4000 extra-solar planets are known today, only a small fraction of these has been captured in an image. To better understand the planet formation mechanisms in solar-like environments we started the Young Suns Exoplanet Survey (YSES).

OB associations are loose groups of young, massive stars. They constitute the last stage of the massive starformation process, and the context in which new stars are formed.

In this dissertation (titled: Exploring the Synergies between Transfer in Reinforcement Learning and Procedural Content Generation) we explore how the two research fields named in the title, namely Transfer in Reinforcement Learning (TRL) and Procedural Content Generation (PCG) can synergize togethe…

All crested and marbled newts (the genus Triturus) suffer from an unusual genetic abnormality, called a balanced lethal system, that kills exactly half of their offspring. How can a trait so disadvantageous have survived millions of years of natural selection?

In this thesis, we address two problems concerning the tautological rings of the moduli space of curves.

In this Yearbook you will find some fascinating examples of what was done in 2021, not only by ourselves, but also by our international colleagues.

GLOBOX is a spatially differentiated multimedia fate, exposure and effect model. It is used for the calculation of spatially differentiated LCA characterisation factors on a global scale.

Europese burgers worden geconfronteerd met uitdagingen op het gebied van globalisering, migratie, technologische ontwikkelingen en klimaatverandering. Deze uitdagingen vergen het uiterste van onderlinge internationale en intergenerationele solidariteit, wat rechtstreeks betrekking heeft op de grondslagen…

During the summer, we organize a summer school for researchers who want to learn about communicating science to diverse audiences. The summer school is aimed at researchers in any career stage who are new to science communication. The Summer School is open for all disciplines in science, including social…

De eerste index om de veiligheid, duurzaamheid en circulariteit van producten te meten, waarmee ze het EU-kader (SSbD) operationaliseren.

This thesis takes steps toward understanding the interaction between gas-phase and solid-state molecules in star- and planet-forming regions.

The main topic of this PhD thesis is the Arakelov ray class group of a number field, an algebraic object that contains both the ideal class group structure and the unit group structure.

Over the past two centuries, socioeconomic development has improved material living standards but has also intensified environmental pressures, including climate change and biodiversity loss.

In this thesis chemical and physical processes in the ice mantles on interstellar dust grains are studied.

This thesis comprises the development of reproducible synthesis procedures for two-dimensional materials (composed of boron, nitrogen and carbon) on different metallic surfaces.

Stellar feedback is a crucial ingredient in the evolution of galaxies.

Dit artikel biedt een systematisch literatuuronderzoek van de belangrijkste principes, normen en strategieën van Security by Design en Privacy by Design.

Hoe worden nachtruimtes verbeeld, geproduceerd, ervaren en verteld door migrantengemeenschappen in Europa? Dit onderzoeksproject onderzoekt deze vraag in acht Europese steden: Aarhus, Amsterdam, Berlijn, Cork, Galway, Lissabon, Londen en Rotterdam.

The majority (80%) of e-waste generated globally are recycled informally in developing countries.

In 2009-2010 ontstond in het westerse discours het idee van een meer ‘assertief’ China, een opvatting die China krachtig van de hand wijst. Niettemin is, vooral sinds Xi Jinping in 2012 aan de macht kwam, duidelijk dat China zijn lang gehanteerde buitenlandse beleidsdoctrine van ‘een lage profilering…

Atoms and molecules are the basic units of matter. If we keep dividing a bar of gold or a glass of water into smaller parts, at the end we are left with a single gold atom or a water molecule.

This thesis introduces a relational interaction model and a practical tool for describing, visualising and generating interactive dialogues.

Drug development is a time- and resource-consuming process that starts with the discovery and validation of a (protein) target that contributes to pathogenesis or disease progression.

To address the fundamental questions of how life on Earth emerged and how common life may be in the Universe, it is crucial to know the chemical composition of the planet-forming material.

The focus throughout this thesis will be on gathering fundamental studies of the detailed structure and composition of the electrode/electrolyte interface effect on the rate and mechanism of key electrocatalytic reactions.

Fungal food spoilage often starts with a contamination with spores. Experimental data strongly indicate the existence of subpopulations of spores with different levels of resistance to preservation methods.

Innovation plays an essential role in firms' competitiveness and long-term success. It varies from different types, ranging from run-of-the-mill innovation that brings incremental changes to existing technologies to radical innovation that breaks from existing trajectories.

Hot astrophysical plasma is ubiquitous in the Universe, from comets in our Solar system to the largest scale structures -- the cosmic web filaments. These hot plasmas, with the temperature of a few millions of degrees, are often observed in the X-ray wavelength range.

In the early universe, the dynamics of the Higgs field can give rise to many interesting phenomena.

Why do sexual violence policies still fail to systematically address men and masculinities, when the need for cultural change among men has been central in public debates since #MeToo?

The dissertation offers new tools and insights to computation and modelling of topological phases, with an emphasis on the aperiodic setting.

The focus of this thesis is how stars like our Sun and planets like Jupiter, Saturn, and Earth are formed.

Material circularity and energy efficiency are highly relevant and intertwined issues for the transition towards a carbon-neutral and circular built environment. In the Netherlands, the building sector has been rendered a priority towards a circular and low-carbon society.
