This thesis seeks to combine two different research topics; Multi-Objective Optimization and Complex Network Analysis.

For many system in statistical physics the microcanonical and canonical ensemble are equivalent in the thermodynamic limit, but not for all.

In this thesis, we show that we can use Shimura’s CM theory to explicitly compute the Hilbert class field of any primitive quartic CM field.

Protein–protein complexes are formed via transient states called encounter complexes that greatly influence the formation of the stereospecific complex.

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.

What invertebrates are available to feed nestlings in an agricultural landscape of varied complexity?

The goal of the project is the development of stream mining techniques for complex patterns such as graphs. We will try to extend the existing state-of-the-art techniques into two, orthogonal directions: on the one hand, the mining of more complex patterns in streams, such as sequential patterns and…

This thesis is comprised of three chapters covering the theme of studying semistable varieties by looking at their dual combinatorial objects.

Essays in Archaeology and Assyriology Dedicated to Diederik J.W. Meijer in Honour of his 65th Birthday

In photoactivated chemotherapy (PACT), a biologically active compound is caged by a light-cleavable protecting group.

The research groups within the biological, soft and complex systems research area study the physics of a broad range of biological and soft materials. This spans both experimental and theoretical research.

The Leiden Complex Networks Network (LCN2) aims at bringing together scientists from different disciplines, based on a common interest in both theoretical models and empirical analyses of networks and graphs.

This thesis describes the genetic and prokaryotic diversity of giant barrel sponges.

Unravelling networks of human mobility and exchange of goods and ideas from a pre-colonial, pan-Caribbean perspective

We study the physics of a broad range of biological and soft materials

The complexity of an intelligence problem determines to a great extent the certainty that can be provided by intelligence and security services.

In this thesis, the researcher developed a nanosystem based on the metallophilic Interaction between cyclometalated complexes.

Issues such as climate change, the depletion of natural resources or social inequality are too complex to be addressed from a single scientific discipline or by a single country. Leiden University has the expertise to bring the resolution of these enormous problems a small step closer.

Stars like the sun are born in large molecular clouds existing from gas and dust. During the formation process, the chemical composition of the material can be altered drastically by the changing physical conditions.

The community & communication workgroup serves as an umbrella that – in addition to its own activities – works with all three workgroups on the community and communication related aspects of their activities

From surface science towards industrial practice using high-pressure scanning tunneling microscopy.

In vitro disease models play a fundamental role in drug research. They enable the systemic identification and validation of disease mechanisms and the discovery of possible drug targets. However, more than often, drug candidates that are identified in vitro fail in the later clinical stages of drug…

This project develops methods for ensuring the anonymity of individuals in social network data.

What tools can be applied to measure the output, outcome and impact of science communication efficiently and effectively?

The aim of this project is to determine in which cases uncertainty statements resulting from a Bayesian statistical analysis can be trusted.

Light-Harvesting Complex II (LHCII) is responsible for light absorption and excitation energy transfer in plants and photosynthetic algae, while in high light it undergoes conformational changes by which it quenches excitations to prevent photodamage.

As a virtually inexhaustible source, solar energy plays a major role in future global energy scenarios.

In this dissertation, the synthesis and characterization of a series of iron complexes based on different ligand platforms are described.

I will give a general introduction to the field of molecular electronics, its history, methods and challenges. I will also introduce the subject of my investigation and provide a brief outlook to the remainder of our thesis.

Complex systems can be characterized as systems in which multiple components interact with each other, often in non-linear ways. The main goal of this research will be to investigate if and how the international tax system can be defined and modelled as a complex system. Approaching the international…

The Gulf is a major global destination for migrant workers, with a majority of these workers coming from South Asia. In this book, a team of international contributors examine the often-overlooked complex governance of this migration corridor. Going beyond state-centric analysis, the contributors present…
