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.

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…

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.

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,…

Throughout the year, the organisation 'Voedsel Anders' organizes an events series that showcase various local food initiatives in Dutch cities.

Nanomaterials can pass much further along the food chain than was previously thought. The particles can change shape and size in each organism, enabling them to pass on to the next one in the chain. Researchers from the Institute of Environmental Sciences discovered this accidentally when using a novel…

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.

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.

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

This minor critically examines the complexities of food sustainability through ecological, socio-economic, political, and cultural systems.

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

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).

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.
