A large diversity of exoplanetary systems has been found, but it is still unclear what drives this diversity.

DNA carries various forms of information. Out of these forms of information the most well-known is classical genetic information.

By training with virtual opponents known as computer generated forces (CGFs), trainee fighter pilots can build the experience necessary for air combat operations, at a fraction of the cost of training with real aircraft.

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

This thesis is about augmented reality (AR). AR is commonly considered a technology that integrates virtual images into a user’s view of the real world.

This thesis manuscript explores the use of video games as tools for conceptual exploration and academic research.

Plant diversity is essential for us and our planet as it sustains the stability of our ecosystems, provides vital materials and food to us and supports many ecosystem services.

This thesis is a collection of theoretical works aiming at adjusting quantum algorithms to the hardware of quantum computers.

The specialisation Science Communication and Society (SCS) concerns science communication in a broad sense. The program focuses on the link between science and society and covers knowledge and skills in the field of science communication.

Pulsars were first discovered in 1967 and since then the population has grown and expanded over several wavelengths.

The function of TLRs in innate immunity has aroused worldwide attention soon after its discovery. Because of the broad functions of TLR2 in innate immunity, the drive for the development of TLR2-targeted vaccines or therapeutic treatments has accelerated in the last decades.

This thesis focuses on the social dimensions of crane and wetland conservation in rural landscapes in Kenya, Uganda and Zimbabwe.

This thesis studied in depth the energy use and CO2 emissions of the industrial sector in China.

In this thesis it is posed that the central object of preference discovery is a co-creative process in which the Other can be represented by a machine. It explores efficient methods to enhance introverted intuition using extraverted intuition's communication lines.

De onderzoeksgroep Governance of Crises bestudeert fenomenen, dynamieken en actoren die te maken hebben met crisisgovernance. Het Crisis Research Center (CRC) van de Universiteit Leiden maakt deel uit van deze onderzoeksgroep.

Op 17 november 2021 verdedigde Cyril-Igor Grigorieff het proefschrift 'The Regime for International Air Carrier Liability'. Het promotieonderzoek is begeleid door prof.dr. P. Mendes de Leon en prof.dr. V. Correia (University Paris Saclay).

This thesis is comprised of three chapters covering the theme of studying semistable varieties by looking at their dual combinatorial objects.

In a typical glycosylation reaction, a donor is activated to form a (variety of) electrophilic species which can react with a nucleophilic acceptor, following a reaction mechanism having both SN1 and SN2 character.

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?

Protein–protein complexes are formed via transient states called encounter complexes that greatly influence the formation of the stereospecific complex.

The four possible segments A, T, C and G that link together to form DNA molecules, and with their ordering encode genetic information, are not only different in name, but also in their physical and chemical properties.

The chemical and structural heterogeneity of toxoid vaccines makes their analysis challenging. However, detailed insights on a molecular level can be obtained by mass spectrometry.

Artful Mathematics: The Heritage of M. C. Escher

The genetic information of all living organisms is contained in their DNA. Cells modify the degree of DNA compaction by epigenetics, which largely determines what genes are read out and which genes are transcriptionally silent.

In this thesis we study the landscape of gravitational models which modify GR by introducing an additional scalar degree of freedom (d.o.f.) to source Cosmic Acceleration.

We explored how to morphologically classify well-resolved jetted radio-loud active galactic nuclei (RLAGN) in the LOw Frequency Array (LOFAR) Two-metre Sky Survey (LoTSS) using machine learning.

Spectroscopic studies on fluorescent single molecules in organic condensed matter does not only provide information about the molecule itself, but also its near environment. By suppression of phonon-induced broadening of spectral lines through cooling to low temperatures, small changes in the spectral…

This thesis presents insights from our study of various correlated electron systems with a scanning tunneling microscope (STM). In ordinary metals, electron-electron interactions exist, but get substantially screened due to the sheer number of electrons.

Technologies that help to enhance our educational environments can be found everywhere.

Humans and songbirds learn their vocalizations early in life by exposure to the vocalizations of adult conspecifics. Often, better learning outcomes are achieved with live, social, tutors than with audio-only exposure to vocalizations.

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…

This dissertation advances automated negotiation by developing agents that can learn and adapt across diverse negotiation settings through three increasingly sophisticated approaches: automated algorithm configuration, portfolio-based strategy selection, and end-to-end reinforcement learning with graph…

Plastics have become an integral part of modern society due to their versatility and durability.

Empirical Legal Studies in Leiden focuste op het bouwen van een interdisciplinaire gemeenschap van rechtsgeleerden en sociale wetenschappers die samen juridische vraagstukken onderzochten op het snijpunt van recht en gedrag, waarbij diverse soorten methoden werden gebruikt.
