Mechanical forces are known to play an important role in bacterial colonies. In this dissertation, we study the self-organization at various stages of growing bacterial colonies, and focus on the mechanical effects of cell growth.

In this thesis, we study systems of electrons in which strong correlations give rise to emergent exotic physics.

In this article, Honorata Mazepus, assistant professor at the Institute of Security and Global Affairs, and Dimiter Toshkov, associate professor at the Institute of Public Administration, discuss whether the winner–loser gap extends beyond the political domain to subjective health and well-being as…

The physical origin of the dozens of stellar-mass binaries, the mergers of which have been detected by the LIGO-Virgo-KAGRA collaboration via gravitational waves, is still unknown.

How can complexity science advance intelligence transformation?

The project Multimedia Research and Documentation of African Oral Genres: Connecting Diasporas and Local Audiences (Director: D.Merolla) focuses on multimedia as technology that allows scholars to share documentation and scientific knowledge with the cultural owners of the collected oral genres.

This article aims to provide a coherent foundation for empirical studies of interpersonal discussion on risk.

Mission statement

Novel entities may pose risks to humans and the environment. The small particle size and relatively large surface area of micro- and nanoparticles (MNPs) make them capable of adsorbing other novel entities, leading to the formation of aggregated contamination.

On the 4th of September, Elisabeth J. Kerr successfully defended a doctoral thesis. Leiden University Centre for Linguistics congratulates Elisabeth on this achievement!

In this article, Meier & Nadler suggest that while non-citizen enfranchisement boosts participation across all citizens, citizens with immigration backgrounds are more reactive to the NCV rights in terms of higher turnout. In this way, the paper adds a critical nuance to individual-based explanations…

Leiden Observatory provides a dynamic, international environment for work and study. Established in 1633, the institute has a very rich tradition. The famous Old Leiden Observatory is the oldest operating university observatory in the world. At Leiden Observatory we carry out world class research and…

How have the armed forces of the United Kingdom, the Netherlands and Belgium adapted to the OMLT task in Afghanistan, and what institutional changes have materialised as a consequence of this adaptation?

The first results of the “Policing European Metropolises project” (PEMP) that associate Professor Elke Devroe and Professor P. Ponsaers launched in April 2013 are now published. Having been the referent for The Netherlands and Belgium in the Urbis project (Leonardo programme), the project focuses on…

How do we experience electronic music? How does electronic music operate on perceptual, cognitive and affective levels? What are the common concepts activated in the listener’s mind when listening to electronic music? Why and how are these concepts activated?

On the 5th of September, Zhen Li successfully defended a doctoral thesis. Leiden University Centre for Linguistics congratulates Zhen on this achievement!

In astronomy, the interpration of observations and measurements plays a crucial role: we rely purely and fundamentally on the information that reaches us as observers. And 80% of all matter in the universe is undetectable directly.

Irna Hofman defended her thesis on 10 January 2019.

How does the cluster bootstrap procedure in combination with various types of linear models perform in the analysis of longitudinal data, compared to other methods.

In this thesis I highlight the applications of Oxford Nanopore Technologies (ONT) sequencing. This technique is a relatively new approach in the sequencing field, where nanopores are embedded in a membrane, DNA molecules are pulled through nanopores and an electrical current serving as the sequencing…

Marc Koper’s research focuses on electrocatalysis and electrochemical surface science for sustainable energy and chemistry. Reactions of interest are the redox reactions of the oxygen/hydrogen cycle (water oxidation, hydrogen evolution), the carbon cycle (reduction of carbon dioxide, oxidation of small…

This paper aims to understand the most common underlying problems causing strategic surprise in the context of the European Union.

Geometric phases lead to a nontrivial interference result when an electron's different quantum mechanical paths choices encircle a magnetic coil in an Aharonov-Bohm experiment.

My work focuses on a class of astronomical objects called protoplanetary disks.

How and to what extent does AI affect citizen representation in public service delivery and state-citizen interactions?

This dissertation explores Aristotle’s use of teleology as a principle of explanation, especially as it is used in the natural treatises.

Natural resources often stretch across borders that separate modern nation states. This can create conflict and limit opportunities for regulated consumption of their goods and services, but also provide opportunities for joint multinational efforts that exceed single country capabilities.
