What factors can explain the dynamics of de facto statehood in Iraqi Kurdistan at internal, national and international levels? What has been the nature of the de facto statehood in Kurdistan since its inception?

In this thesis, the focus lies on studying glucocorticoid receptor dynamics in living cells with the aim of understanding how this transcription factor finds its DNA target sites to regulate transcription.

Here are some systems and infrastructures that are useful to students.

The aim of the research programme Systems Pharmacology lies in the development of personalised medicine strategies, and development of new systems-based approaches in translational and clinical pharmacology.

This is the first special issue of any organisation studies journal on food labour. Why is this a big deal? In this Introduction, we argue that the field should pay much more attention to the agri-food system and the work that goes into producing, distributing and consuming foodstuff. Food is such an…

The 9th Network Europe Conference in Edinburgh was held at June 2017 in Edinburgh and organized by the Europa Institut Zurich. The contributions of the conference are now published.

Immunologist Leender Trouw specialises in the complement system, which is part of the immune system. In some diseases drugs help activate or inhibit this system. This is best done ‘in the right place at the right time’ − the title of his inaugural lecture.

Can process-oriented dynamic testing be applied to everyday educational practice?

Dutch coalition parties VVD and CDA want to tighten asylum policy and have launched a plan to grant two types of statuses to refugees. They also intend to partially restrict the right to family reunification. However, this plan is facing strong opposition. With the proposal, the government can expect…

Every year, Leiden University welcomes some 27,000 students from 115 different countries. In educating these students, we are committed to ensuring that the quality of our tuition meets or exceeds the highest-possible standards.

Adenosine is an endogenous ligand which exerts its action by activating adenosine receptors (ARs), while its circulating levels are controlled via a variety of mechanism and proteins, amongst others the equilibrative nucleoside transporters (ENTs).

This research area is focused on the development and application of novel concepts and models in the emerging area of quantitative systems pharmacology (QSP).

Researchers at LIACS are working to devise the computers of tomorrow that will be the backbone of the Cloud and Edge computing paradigms as well as the Internet of Things. In this respect, we are involved in research and development of high performance computing systems, embedded & real-time computing…

According to the amyloid cascade hypothesis, accumulation of beta-amyloid (Aβ) peptides initiates the pathological cascade in Alzheimer's disease (AD).

In autoimmune diseases such as rheumatism and diabetes the immune system attacks autologous proteins. Leiden researchers are trying to discover how this comes about.

Mathematical models of software systems enable characterizations, abstractions, simulations, and analysis of complex software during its development.

The correctness of computational systems is of great importance to our society, since it becomes ever more reliant on the benefits of computing.

Making systems biology modelling a central pillar of research in biology

How do balanced lethal systems originate and persist in nature?

There is currently a problem with our ticket registration system. We are looking for a solution.

This book is about the workings of networks of the mobile in Africa, a continent usually associated with the ‘global shadows’ of the world.

Why does one person radicalize to involvement in terrorist violence within a group-based context, while another engages in this form of violence alone?

Every organisms in the tree of life faces the same challenge: the length of its DNA exceeds the volume of the cell it needs to fit in. Several strategies have evolved to solve this problem, one of them being the expression of proteins that bind and organize the DNA.

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…

Across many decision-making tasks, people and animals systematically repeat (or alternate) their choices - even when the choices they make are intrinsically uncorrelated. This phenomenon (also known as 'sequential effect' or 'choice hysteresis') has been known for at least a century, and may be a stable…

The master's specialisation Bioinformatics at Leiden University focuses on research, development and application of computational tools and approaches for expanding the use of biological, medical, behavioral and health data.

This thesis provides explicit expressions for the density functions of absolutely continuous invariant measures for general families of interval maps, that include random maps and infinite measure transformations, not necessarily number systems.

Interaction between Legal Systems acknowledges that law-making and law enforcement are increasingly taking place on various levels: in a global context, in EU context, on a national level and in a private law framework. These levels influence each other, sometimes directly, on the basis of a hierarchical…

This thesis studies operator-algebraic aspects of subproduct systems, a generalization of product systems of Hilbert spaces.

In condensed matter systems electron-electron interactions, negligible in everyday metals, can dramatically alter the electronic behavior of the system. Examples of such altered behavior include high-temperature superconductivity and modulation of the electron density.

The ambition of the Medical Systems Biophysics and Bioengineering group led by Alireza Mashaghi is to develop and use physics and engineering concepts and tools for pathophysiology, diagnostics and therapy.

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.
