Understanding others’ emotional behavior is essential for navigating daily social life. But how is such an understanding achieved? The eye-tracking study by Yung-Ting Tsou and colleagues shows that children with hearing loss adopt a unique visual strategy that makes uses of explicit visual information…

In this thesis, we focus on novel proteins/mechanisms that regulate integrin-adhesion mediated mechano-transduction.

Unconstrained day-to-day activities are difficult to quantify and how the corresponding movements shape the brain remain unclear. Here, we recorded all touchscreen smartphone interactions at a sub-second precision and show that the unconstrained day-to-day behavior captured on the phone reflects in…

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

HomininSpace is an agent based modelling and simulation system in which fluctuating carrying capacity is the key attractor for hominin dispersal. A parameterized and spatially explicit reconstructed palaeo-environment models available energy in the form of secondary biomass using reconstructed climate…

The dissociative chemisorption of methane on metal surfaces is of fundamental and practical interest, being a rate-limiting step in the steam reforming process. The reaction is best modeled with quantum dynamics calculations, but these are currently not guaranteed to produce accurate results because…

Discovery and development of Central Nervous System (CNS) drugs is hampered by high attrition rates.

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…

Vinasse is a major by-product generated by the sugarcane biofuel industry. It is a source of microbes, nutrients and organic matter and often it is recycled as fertilizer.

Inflammatory skin diseases such as psoriasis and atopic dermatitis can severely impact both the physical and social aspect of a patient’s life. Aberrant inflammatory responses are thought to be a major causative factor in these disorders, but an abundance of different factors contribute to the development…

How are carbohydrates processed by the immune system? Can carbohydrates be used to trigger T-cells against other conjugated antigens? Can they be used as adjuvants?

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

Uncovering task solving processes in dynamic testing

The main question of this research project concerns the extent to which light verbs in West Germanic languages participate in processes of language change.

A network combining 9 academic research groups and 4 collaborating industrial companies will train the next generation of PhD students and post-doctoral researchers, in developing and applying novel experimental and theoretical methods in the NMR spectroscopy of systems containing paramagnetic metals.…

Big data promises to transform public decision-making for the better by making it more responsive to actual needs and policy effects. However, much recent work on big data in public decision-making assumes a rational view of decision-making, which has been much criticized in the public administration…

In the week of July 1st - 5th there will be a summer school on "Data science for dynamical systems" at the Lorentz Center in Leiden.

On the 23rd of March, Alessandro del Tomba successfully defended a doctoral thesis and graduated. The Leiden University Centre for Linguistics congratulates Alessandro on this achievement!

The experimental approach of science applied to artistic research

This project investigates the transposition of natural historical material, knowledge and vision, between different media (collection, scientific drawing, academic texts, the visual arts and/or literature) – a transmission that happens in the borderline between the traditional, emblematic worldview…

PhD defence

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.

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…

The European Council and the European Commission have a similar role in agenda setting. Both place issues on the EU agenda. However, these institutions have distinct designs. They have different political attributes (the European Council has considerably more political authority) and information-processing…

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,…

Mathematics forms the basis of many innovations in technology, the service industry and science, such as data analysis and coding, artificial intelligence, weather or climate change modelling or understanding molecular processes. The researchers from the Mathematical Institute (MI) are constantly developing…

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.

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.
