Understanding the formation and evolution of planetary systems is one of the most fundamental challenges in astronomy. To directly image and study young exoplanets and the circumstellar disks they form from, dedicated high-contrast imaging instruments are built.

The main research question of this thesis was: Can nitrogen cycling on dairy farms on peat soil in the Dutch Green Heart area be improved by adapting management to the nitrogen supply from soil and by using other grassland species and crops without affecting milk production?

Explaining treatment response variability between and within patients can support treatment and dosing optimization, to improve treatment of individual patients.

Leiden University offers a unique range of summer courses where you can broaden or deepen your knowledge or share your expertise with fellow students. The choice of academic courses is very diverse, ranging from Law, Big Data, Languages and Linguistics to Maths and Natural Sciences, Biology, Biomedical…

From the 1920s on, popular music in Southeast Asia was a mass-audience phenomenon that drew new connections between indigenous musical styles and contemporary genres from elsewhere to create new, hybrid forms. This book presents a cultural history of modern Southeast Asia from the vantage point of popular…

Since its beginnings, Leiden University has been home to scholars with a broad and diverse expertise in the histories, languages, literatures and material cultures relevant to the study of Jews and Judaism from antiquity to modern times.

Early time-resolved experiments by Frauenfelder on the ensemble of the kinetic rebinding of CO to myoglobin molecules resulted in a stretched exponential relaxa-tion due to a very large spread of the reaction rates of individual molecules.

Electrons in a crystal lattice have properties that may differ from those of a free electron in vacuum.

In the thesis the dynamics of strategies is studied from two perspectives.In the first part of the thesis strategies are considered to be opinions present in a community.

Due to the almost complete disappearance of the archive of the Old Dutch West India Company (WIC, 1621-1674) not much is known about the ships and crews of this company. In this project we start the reconstruction of this basic information making use of new digital humanities techniques to extract this…

This thesis contains results on the arithmetic and geometry of del Pezzo surfaces of degree 1.In Chapter 1 we give the necessary background, assuming the reader is familiar with algebraic geometry.

This thesis describes a study from both a theoreticaL and an experimental point of view.

Polycyclic aromatic hydrocarbons (PAHs) are the most abundant class of organic compounds in space. The PAH field evolves from the constant interaction between experimentalists, theorists, modellers and observers. While laboratory research and quantum chemical calculations together set up the molecular…

Clinical development of drugs for central nervous system (CNS) disorders has been particularly challenging and still suffers from high attrition rates.

Sustainable energy from wind and solar is most readily available near the sea.

Optimization tasks in practice have multifaceted challenges as they are often black box, subject to multiple equality and inequality constraints and expensive to evaluate.

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-…

In this thesis we will explore the use of fuzzy systems theory for applications in bioinformatics.

The way organisms develop from the initial single-cellular state to a complex final assembly like the human body, and how the final body is maintained throughout life, is one of the greatest mysteries and it’s understanding one of the biggest scientific challenges.
