This thesis concerns the relation bettween the good reduction of Shimura varieties and the associated loop groups.

Errors are everywhere, and mechanical failures are especially common: buckled grain silos and cracked support columns are, justly, seen as an issue to be avoided.

N-acylethanolamines (NAEs), including N-arachidonoylethanolamine (anandamide, AEA), N-palmitoylethanolamine (PEA) and N-oleoylethanolamine (OEA), are signaling lipids that play an important role in different physiological process.

This book explores the spiritual potential of faith, mysticism and transcendence in answer to the dangers of a mythologised state and the sacro-sanctification of (liberal) democracy and its rule of law.

Carbonaceous asteroids preserve a record of early solar system processes, where minerals and organic molecules, like polycyclic aromatic hydrocarbons (PAHs), offer clues to planetary evolution and prebiotic chemistry.

A New Technology-Based Firm (NTBF) is a significant enabler of job creation and a driver of the economy through stimulating innovation.

Throughout the history of computer science, a major challenge has been how to assert that software is free of bugs and works as intended. Software bugs can lead to serious negative impacts on any software system. Throughout the main body of the thesis, we implemented a series of studies on exploring…

The development of new environmentally sound technologies is seen as a key route towards achieving sustainability.

Pharmaceutical companies, governments and the general public have become increasingly aware that animal models used in drug testing lack vital aspects to serve as an accurate representation of human biology. As models of the human body should become more physiologically relevant, animal models no longer…

Including modelling as part of software development appears to have various benefits.

This thesis is devoted to an in-depth examination of the various effects of disorder in the cuprate high-temperature superconductors.

Regeneration is the ability of an organism to restore damaged or lost tissue with a functional replacement, and without scarring. Many lizards can regenerate their tails.

For centuries astronomers studied the Universe by collecting light. Nowadays, we are living in times of great technological advancements, which allow us to explore our Universe in a new way - though gravitational wave radiation.

Cancer is considered the silent pandemic of the 21st century and the second leading cause of death worldwide.

This thesis describes the development and validation of new high-contrast imaging techniques, with the ultimate goal of enabling the next generation of instruments for ELT-class telescopes to directly image Earth-like extra-solar planets orbiting around nearby stars.

The soil-dwelling, filamentous bacteria of the genus Streptomyces are renowned for their production of useful secondary metabolites including antibiotics. The work described in this thesis provides new insights on the role and regulation of antibiotic production and resistance in these bacteria.

Dissolution processes – next to aggregation processes - play an important role for fate prediction and environmental risk assessment of metal-based nanoparticles (MNPs). It is challenging to predict the kinetics of the dissolution process of MNPs in complex systems such as we can find in in vivo and…

Globally and regionally, biodiversity is declining and there are shifts in species’ occurrences and functional traits.

In today's volatile market environments, companies must be able to continuously innovate. In this context, innovation does not only refer to the development of new products or business models but often also affects the entire organization, which has to transform its structures, processes, and ways of…

In-use stocks of products can be considered as intermediaries between human needs and the physical world.

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…

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”.

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.

What holds people together and what makes them willing to fit within larger political structures? Our project examines this question in the practices of dynastic rulership in Eurasia ca. 1300-1800.

Deze eenjarige Nederlandstalige masterspecialisatie onderzoekt Nederland en zijn mondiale en koloniale context, vanaf de middeleeuwen tot nu.

In Duitsland, Amerika en zelfs in Vietnam: overal ter wereld werd de Leidse ontdekking gedeeld van de geboorte van twee planeten. Astronoom Sebastiaan Haffert wist met zijn team voor het eerst meerdere planeten in wording vast te leggen en publiceerde zijn bevindingen in Nature Astronomy. Een unieke…

Drie onderzoekers van de Faculteit der Wiskunde en Natuurwetenschappen ontvangen een TOP-subsidie Exacte Wetenschappen. Dat maakte NWO op 22 november bekend.

Wetenschappers hebben een neutrino ontdekt met de hoogste energie ooit gemeten. Leidse natuurkundigen Maarten de Jong en Dorothea Samtleben werkten mee aan dit project, waarover afgelopen week te lezen was in alle kranten en op alle online media.

De Leidse hersenonderzoeker Elseline Hoekzema bewees dat de hersenen van moeders ingrijpend veranderen tijdens de zwangerschap. Daarover vertelt ze bij de NTR in De Kennis van Nu.

This pioneering project will answer this question by examining migrants through the eyes of the courts between 1600 and 1900. It aims to reveal patterns of continuity and change in: 1. Treatment of migrants by criminal courts; 2. Violence and conflicts between migrants and native born.

Sterrenkundigen gebruiken een nieuwe supercomputer om de enorme hoeveelheden data van de LOFAR telescoop te verwerken. Naar verwachting zullen de data nieuwe inzichten bieden in het ontstaan van melkwegclusters en quasars.

The basic program comprises a total of twelve courses organized by the Research School, that have been purpose-developed for training and support of PhD students and Research MA students who specialize in Medieval Studies (history, art history, and literary history, in particular).
