How can we explain that Caribbean small states have the most stable two-party systems in the world, while Pacific small states have either very weak parties or no parties at all? Matthew Louis Bishop (University of Sheffield, UK), Jack Corbett (University of Southampton, UK) and Wouter Veenendaal (Leiden…

Neurodegenerative diseases, including Parkinson’s disease (PD), are increasing in prevalence due to the aging population. Despite extensive study, these diseases are still not fully understood and the lack of personalised treatment options that can target the cause of the diseases, rather than the symptoms,…

Following their application to system biological models, control theory techniques have further potential to aid in the understanding and application of quantitative systems pharmacology models.

Systems with local constraints is a new finding in recent researches on complex systems. The heterogeneous spatial interactions and the temporal dependencies among those numerous units make it difficult to describe by traditional statistical physics.

In this thesis, mathematical modeling and simulation was applied as a tool to inform quantitative decision making in oncology drug discovery and development.

We have studied the impact of particle shape anisotropy, multivalent interactions and flexibility on systems of micron-sized colloidal particles.

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

Electoral Systems and Turnout: Evidence From a Regression Discontinuity Design. In this article, published on the website SAGE research methods, authors Jaroslaw Kantorowicz and Tobias M. Hlobil discuss how a Regression Discontinuity Design can be executed.

In the hunt for a vaccine against cervical cancer, fundamental knowledge about the immune system and organic chemistry have been brought together and have already resulted in a vaccine that is now being tested in clinical trials. Scientists are now working hard on an improved variant.

In this book liposomes are explored as delivery system for allergen-specific immunotherapy. Both cationic and anionic formulations are prepared with Bet v 1, one of the allergens in birch pollen.

We have developed a microfluidic platform for complex 3D organotypic cell cultures (so-called organ-on-a-chip systems) which are suited for integration in 96 or higher well plate format.

In autoimmune diseases such as rheumatism and diabetes the immune system attacks autologous proteins. Leiden researchers are trying to discover how this comes about.

What is the environmental impact of different waste collection systems across Europe? How can the collection be improved when considering collection, sorting, and treatment, as well as use options for secondary materials?

Pathways of toxicity

Cardiovascular diseases are among the most frequent causes of death in the world. The main underlying pathology of cardiovascular diseases is the development of atherosclerosis in the medium and large-sized arteries.

On 25 January 2018 Yannick van den Brink defended his doctoral thesis titled ‘Voorlopige hechtenis in het Nederlands jeugdstrafrecht’ (‘Pre-trial detention in the Dutch juvenile justice system’). The doctoral research is supervised by Professor Ton Liefaard and Professor Mariëlle Bruning.

The key characteristic of active matter is the motion of an emergent collection (such as a flock of birds), which is driven by the consumption of energy by its active components (i.e. individual birds).

Tax scandals, like the Panama Papers, the Paradise Papers, and the Pandora Papers, have made taxation a major topic of public debate. Learn more about this in the new minor Tax and Society: Building a Sustainable and Fair Tax System.

Does powerlessness and dependence lead to the legitimation of the social, political, and economic status quo and of those in authority?

The Collective Experience of Empathic Data Systems (CEEDs) consortium developed novel integrated technologies that support experiencing, analysing and understanding of very large datasets.

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.

The first objective is to create a catalogue raisonée, i.e. a structured database that will store the main attributes of each town in a standardized format database, which will be freely accessible when completed; the second objective is to exploit theories and methods that can help us to understand…

To what extent is the legislation and use of pre-trial detention of juveniles in the Netherlands in compliance with international children’s rights standards?

The Horizon 2020 project Sybil-AA (Systems Biology of Alcohol Addiction) focuses on modeling and validating disease state networks in human and animal brains for understanding pathophysiology, predicting outcomes and improving therapy in alcohol addiction. Alcohol addiction, the most severe form of…

Generations of Leiden students and academics have done archaeological research into the early medieval history of Oegstgeest. This makes this old settlement one of the best-documented sites from that era. In a new book, Leiden researchers take stock.

The overall objective of this project is to identify novel drug candidates that are capable of slowing down the progression of neurodegeneration in the subset of Parkinson’s disease (PD) patients with overt mitochondrial dysfunction. Multimodal phenotypic characterisation of cohorts of monogenic PD…

Intelligence of the crowd, or in other words, intelligence of a large, random collective, exists mostly in social media platforms such as twitter. The collective does not comprise (at least not necessarily) experts on crises, just regular people mostly. Nevertheless, there is valuable intelligence to…

On 17 December 2018, Dejian Kong defended his thesis 'Civil Liability for Damage caused by Global Navigation Satellite System'. The doctoral research was supervised by Prof. dr. P.M.J. Mendes de Leon.

On 11 November 2021, Mariana Gkliati defended the thesis 'Systemic Accountability of the European Border and Coast Guard'. The doctoral research was supervised by Prof. P. Rodrigues and Prof. L. Besselink (UvA).

Cardiovascular diseases are the primary cause of death in the world with atherosclerosis as primary underlying cause.

A tidal basin is an inland sea which is almost entirely enclosed by land and connected to the open sea by a tidal inlet. Through the tidal inlets interaction takes place between the tidal basin and the open sea.
