Drug-induced liver injury (DILI) is one of the main reasons for drug attrition during pre-clinical and clinical phases of drug development as well as for drug withdrawal post-marketing.

More than 5,000 exoplanets have been found over the past couple of decades. These exoplanets show a tremendous diversity, ranging from scorching hot Jupiters, common super-Earths, to widely separated super-Jupiters on the planet/brown dwarf boundary.

In this dissertation several settings in the Online Learning framework are studied. The first chapter serves as an introduction to the relevant settings in Online Learning and in the subsequent chapters new results and insights are given for both full-information and bandit information settings.

Wetland plants are distinguished from plants of other terrestrial ecosystems by their adaptations to specific habitat stresses, including waterlogged and flooding and the subsequent abundance of phytotoxic compounds.

In light of climate change, it is crucial to determine whether plant species can adapt to future climates to avoid extinction. Plants adapt to various conditions by altering their functional traits, such as leaf size or photosynthetic rate. Some traits appear linked and vary together between species,…

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.

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.

This thesis describes the implementation and on-sky demonstration of high-resolution integral-field spectroscopy for extreme adaptive optics systems that are used to find and characterize exoplanets.

One of the key limitations of the direct imaging of exoplanets at small angular separations are quasi-static speckles that originate from evolving non-common path aberrations (NCPA) to which the primary adaptive optics system is inherently blind. The main focus of this thesis is the development and…

Aan de hand van drie onderzoekslijnen wordt de verbinding tussen zorg en bestuur gemaakt. Binnen deze drie onderzoekslijnen wordt een multi-level benadering gehanteerd. Dat betekent dat we ons richten op vraagstukken op het niveau van het gezondheidszorgstelsel, het niveau van organisaties en netwerken…

Invasive lobular carcinoma (ILC) is the second most common type of breast cancer.

The research of the Applied Mathematics cluster is concerned with such diverse topics as dynamical systems, representation theory, differential equations and pattern recognition.

In recent decades, climate change has led to more frequent and severe drought events, causing serious consequences such as increased forest mortality and significant crop yield losses. Understanding how drought affects plants, especially economically important herbaceous species, is crucial for predicting…

In deep reinforcement learning, searching and learning techniques are two important components. They can be used independently and in combination to deal with different problems in AI, and have achieved impressive results in game playing and robotics. These results have inspired research into artificial…

We have examined sequences from the ligand-binding domain of the nicotinic acetyl choline receptor (nAChR) in 148 vertebrate species. We are in interested in this receptor because the α-neurotoxins of many venomous snakes binds to this receptor in its location at the neuromuscular junction in all ve…

Bij het Leiden Leadership Programme zijn experts op het gebied van leiderschap werkzaam. Zij rusten masterstudenten van de Universiteit Leiden, de TU Delft en de Erasmus Universiteit Rotterdam toe met de nodige kennis, inzichten en vaardigheden op het gebied van leiderschap om zo hun maatschappelijke…

Het onderzoeksproject van Prof.Dr. Arjen Doelman ‘Adaptive Semi-Strong Ecosystem Dynamics’ is geselecteerd voor financiering als een van de 7 onderzoeksprojecten binnen het programma Mathematics of Planet Earth (MPE) van NWO.

Astronomen willen het heelal begrijpen, van de Oerknal tot nu, en hoe dit verder zal gaan. In Leiden concentreren ze zich daarbij op twee vragen: 'Hoe ontstaan sterren en planeten? en 'Hoe ontstonden in het jonge heelal sterrenstelsels en zwarte gaten?' Een nieuwe generatie telescopen – net klaar of…

Paul Brakefield, hoogleraar evolutiebiologie van het Instituut Biologie Leiden (IBL), heeft een ERC Advanced Grant ontvangen voor zijn onderzoek. Hij krijgt 2,5 miljoen euro om in een periode van vijf jaar zijn onderzoeksprogramma verder uit te bouwen.

Athletes always strive for the top. How can data scientists assist them in improving their performance? During the seminar Data Science and Sports, the possibilities and challenges of collaboration between these two worlds were discussed.

Wetlands provide many ecosystem goods and services which include fish production. The sustainability of small-scale fisheries (SSF) has received considerable attention in recent years because fish is one of the major sources of animal protein to a considerable fraction of the global population which…
