Research into research improves the academic system. CWTS studies and evaluates the academic system in various ways. One way is to provide information on the productivity and impact of academics by documenting how many publications they or their universities produce and how often these publications…

Systems pharmacology aims to apply techniques from systems biology to pharmacological models.

High-throughput holistic preclinical screens are increasingly used in drug discovery, to assess both drug efficacy and drug safety.

The experimental approach of science applied to artistic research

The arrival of Columbus to the Caribbean in 1492 marked a milestone in world history. In both the European and the indigenous world, a set of economic, political and hierarchical networks and relations were defined, structured and changed. These changes affected the indigenous population at different…

Osteoarchaeologist Rachel Schats investigates traces of illnesses and disorders in human skeletons. Her search for malaria in the Low Countries' middle ages is central in an article in the Dutch version of National Geographic Magazine of February 2020.

On 29 January 2019, Robbert van Eijk defended his thesis 'Web Privacy Measurement in Real-Time Bidding Systems, A Graph- Based Approach to RTB system classification'. The doctoral research was supervised by Prof. dr. H.J. van den Herik.

Leiden PhD candidate and vet Luc Janssens discovered that a dog found at the start of the last century in a grave dating back 14,000 years had been sick for a long time and had been cared for. He and Thijs van Kolfschoten were interviewed by National Geographic about this discovery.

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…

In this project, M. Riep studies the complexity of historical events related to the Arab conquest of the region along the upper course of the Syr Darya in Central Asia and especially of the micro oases of Shash and Ferghana. This project focusses on mobility, action and dynamics and will place the Arab…

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

Pathways of toxicity

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.

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).

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…

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.

INFORM (Introduction of the data protection reform to the judicial system) is a project granted by the Directorate-General Justice and Consumers of the European Commission.

The major aim is to unravel the central mechanisms of how peoples’ expectancies affect physical symptoms, immune and endocrine responses, and related health outcomes, through the use of pioneering multidisciplinary methods in experimental studies in healthy and clinical populations.

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…
