On the basis of the characteristic aspects of a picture, certain computers can tell us what the picture is showing. They can learn this in the same way that young children are able to learn to recognize images. Further improving these techniques opens the way to a whole range of new applications. Biology…

The availability of indicators based on social media has opened the possibility to track the online interactions between social media users and scholarly entities.

Disciplinary History and Epistemology

Making systems biology modelling a central pillar of research in biology

The archaeology domain produces large amounts of texts, too much to effectively read or manually search through for research. To alleviate this problem, we created a search system (called AGNES), which combines full text search with entity and geographical search.

This thesis explores the theoretical and observational properties of distant massive galaxies that harbour active black holes in their centres and shine brightly at radio wavelengths.

My work is motivated by the necessity to extend Standard Model of Particle Physics in order to explain three observed phenomena that this great theory fails to accommodate

Parassign is a program to assign protein nuclei solely on the basis of pseudocontact shifts (PCS). The PCS from several paramagnetic tags are required, in order to produce several restraints per nucleus.

This study assesses nationwide, disaggregated trends in homicide rates over a 25-year period. Using a unique, detailed dataset, spanning a quarter of a century of homicide data allowed Aarten & Liems to assess type-specific homicide trends and the relationship between gender and age within these tre…

And its application in deciphering hominin diets in palaeolithic eurasia

Natural history collections provide invaluable sources for researchers with different disciplinary backgrounds, aspiring to study the geographical distribution of flora and fauna across the globe as well as other evolutionary processes.

In this thesis, I study the formation of large-scale structure and the physics of particle acceleration at large scales (~Mpc).

The programme group Research Methods and Statistics offers methodological support in many projects in the field of education and child studies.

On 22 November 2018, Els De Busser spoke at a panel during the conference

High resolution altitude data created by airborne LiDAR allow the investigation of large areas and often inaccessible tracts of land and has the potential to reveal undiscovered archaeological heritage.

The Horizon 2020 project CoSTREAM aims to improve our understanding of the co-occurrence of stroke and Alzheimer’s disease. It has long been known that both diseases share underlying causes, but their exact interaction or link is not fully understood. CoSTREAM combines multiple factors to identify and…

The Next444 project focuses on the future of interdisciplinary research at Leiden University.

In this article Fisher, Klein & Codjo introduce the FOCUSdate Project and they show how the sentiment data provide unique abilities to analyze Russia's and Iran's reactions to US policies and events and NGO human rights campaigns.

The current project aims to revive the idea that sound inventories are structured according to a small set of universal principles by applying insights from current phonological theory and by making use of modern database technologies and data assessing methodologies.

The Archaeology of Consumption in the Eastern Mediterranean (ca. 500-1500)

The HOPES study is one of the largest investigations of this kind to date! By studying existing brain scans and data collected form over 4,000 14-25 year olds, the project team hopes to identify specific changes in the brain that make young people vulnerable to suicidal thoughts and behaviours.

This book is about the archaeology of indigenous peoples who thrived across the Caribbean, the Guianas, and the Lower Amazon basin just before the European invasion, and who also remained central to the early history of conquest and colonization.

This study presents an agent-based simulation model exploring the patterns of presence and absence of Late Pleistocene Neanderthals in western Europe.

In recent years, the use of primary data in terrorism research has increased. In order to maximise the benefits of this trend, we want to encourage terrorism scholars to implement open science practices more systematically. This article therefore presents different avenues towards open and reproducible…

What did it mean to be enslaved in in the Indian Ocean world in the 18th and 19th centuries? Over the last decades, historians have mined French, British, Portuguese and Dutch records for quantitative data on the European slave trade. This project focuses on the experience of being a slave and seeks…

The programme group Research Methods and Statistics develops and teaches the large majority of methodological courses in all phases of the program Education and Child Studies.

In 2018, the number of mobile phone users will reach about 4.9 billion. Assuming an average of 5 photos taken per day using the built-in cameras would result in about 9 trillion photos annually.
