This book is the first comprehensive presentation of the archaeology of Syria from the end of the Paleolithic period to 300 BC.

The financial system needs complexity theory to predict economic crises like the 2008 meltdown. An international team of scientists, including Leiden physicist Diego Garlaschelli, state this in a paper published in Science on February 19th.

In this thesis, we extend the concept of null models as canonical ensembles of multi-graphs with given constraints and present new metrics able to characterize real-world layered systems based on their correlation patterns.

The building is far from finished, but the former ministry of Internal Affairs is looking more and more like the Academic building for the locations of the University of Leiden in the Hague that it has to become. This week I got a tour behind the scenes of the gigantic project, where I was able to see…

Manufacturers produce high-end technology mostly top-down with large machinery, but small particles are able to build structures by themselves from the bottom up. A major challenge is that these particles easily clump together. Leiden physicist Daniela Kraft has developed a method to use this phenomenon…

‘It has never been so easy to set up a Studium Generale series.’ With these words Tilman Grünewald thanked speaker Frank den Hollander, who kicked off the Studium Generale series on complex networks on Monday 20 February.

An international team of researchers including Leiden archaeologists has produced convincing evidence that 300,000 years ago pre-Neanderthal people had a high level of cognitive complexity. New insights into early human capabilities and behaviour.

For the first time, astronomers have detected the presence of complex organic molecules, the building blocks of life, in a protoplanetary disc surrounding a young star. The discovery reaffirms that the conditions that spawned the Earth and Sun are not unique in the Universe. The results are published…

The thesis wishes to examine the pathways of thought underlying the creative act of music making and the performance practice of complex music from the late twentieth and early twenty-first century.

The logic seems inescapable indeed. The bigger the population, the higher the probability it contains an Einstein. Hence, bigger populations are more likely to develop complex culture.

It's much easier to learn something if you're interested in it. But students' interests are often diverse and wide-ranging, says Sanne Akkerman, Professor of Educational Science. How do you cater for this in your teaching? Inaugural lecture 6 October.

Scientists often need to make sense of complex systems without knowing the important parameters or even without access to all the information. A collaboration of network theorists, including Diego Garlaschelli (IMT Lucca/Leiden), has now published a review article in the inaugural issue of Nature Reviews…

This thesis has three main parts. The first part gives an algorithm to compute Hilbert modular polynomials for ordinary abelian varieties with maximal real multiplication. Hilbert modular polynomials of a given level b give a way of finding all of the abelian varieties that are b-isogeneous to any given…

Dr. Josien de Klerk, Associate professor in Global Public Health at Leiden University College The Hague recently published some of her work on HIV/AIDS. In collaboration with a team of interdisciplinary researchers from the Amsterdam Institute for Global Health and Development she came to the conclusion…

The first successful Leiden Networks day took place on September 23, 2016. Six world-renowned speakers (see photo) in the field of complexity and network science provided their view on the field.

On Friday 23 September 2016 the Leiden Complex Networks Network day, the LCN2 day, will take place in Leiden.

From a ruinous building site to a lively university building: that is the drastic metamorphosis that the Wijnhaven complex is going through at this moment. The pictures below already show impressions of the end result.

Work started today on the Kolffpad student complex, with 289 flats for students from Leiden University. Stichtnig DUWO will own the building and the University owns the site at the Bio Science Park. The building should be complete by mid-2023.

Monday afternoon 11 January saw the first Public Leadership Challenge: a gathering of professionals, academics and students. The theme was a hotly debated topic: the refugee crisis. Among the participants looking for solutions to this complex issue were four students from the (International) Leiden…

How can we adapt the Dutch we use at the University so that everyone feels comfortable and included? This was the subject of debate during a panel discussion on 28 June at Leiden University.

NWO awarded a grant for novel research on Complex and Distributed Cyber-Physical Systems (CPS). The grant will fund a four-year research project in which they hope to devise a method to explore and find optimal designs for CPS. Todor Stefanov, Associate Professor at the Leiden Institute of Advanced…

Investigating the emergence of complex societies in Chalcolithic Cyprus.

William Pestle and Jason Laffoon recently published a new article entitled 'Quantitative paleodietary reconstruction with complex foodwebs: An isotopic case study from the Caribbean' in the Journal of Archaeological Science: Reports.

The Hague Journal of Diplomacy is calling for research papers. The deadline for submission is the first of June 2018. This will be used for a book and special issue of the The Hague Journal of Diplomacy

Abeer Abazeed, PhD-student at the Institute of Security and Global Affairs, will defend her thesis on Wednesday april 21st. Four questions about her PhD-research ‘Is it One Nile? Civic engagement and hydropolitics in the Eastern Nile Basin’.

Christian Lequesne introduces the upcoming special issue on Ministries of Foreign Affairs in this blog post.

What invertebrates live in the fields and edges? Do the populations change with landscape complexity?

To an algebraic curve C over the complex numbers one can associate a non-negative integer g, the genus, as a measure of its complexity.

This thesis is largely an experimental study on the formation of solid-state simple and complex organic molecules in the H2O-rich and CO-rich ice phases of dense interstellar clouds and dark cores.

NETWORKS, a new consortium of 11 researchers from the University of Amsterdam, Technical University Eindhoven, Leiden University and CWI aims to address the pressing challenges posed by large-scale networks using stochastics and algorithms.

Professor Frank den Hollander has been awarded a 10-year grant through the NWO Gravitation program, jointly with colleagues from the University of Amsterdam, the Center for Mathematics and Computer Science in Amsterdam, and the Technical University of Eindhoven.

On November 24, 2017, Esther Keymolen gave a presentation on Trust in the Networked Era, as part of the annual Philosophy of Technology Lab. This lab is organized by a.r.t.e.s. Graduate School for the Humanities Cologne and CFCU (Centro de Filosofia das Ciências da Universidade de Lisboa). The general…

Scientists at Leiden University (Netherlands), Stuttgart University (Germany) and Ural Federal University (Russia) have successfully put forward a novel, computed, reaction mechanism that was experimentally tested and show that formaldehyde is formed at much earlier stages in the birthplaces of stars…
