This thesis explores Breaking of Ensemble Equivalence (BEE) in random graph models by examining the spectral properties of adjacency matrices. The goal is to identify spectral characteristics that differentiate random graph ensembles, enhancing the understanding of complex network structures and beh…

Take a view on the slides of the presentation and read what the event of Climate Change & Health was about.

In populations with a seed-bank, individuals can temporarily become dormant and refrain from reproduction until they can become active again. The repository of all dormant individuals in the population is called the seed-bank. Seed-banks are observed in many taxa, including plants, bacteria and other…

Each year, the Leiden University Student Platform (LUS) presents the Leiden Education Prize.

On the occasion of prof Paul van der Heijden’s stepping down as Rector Magnificus and President of the Executive Board of Leiden University in 2013 the Chair bearing his name on Social Justice was established. It was a “farewell present” of the Leiden University to it’s Rector.

We strive to address the challenge of constructing a modeling language to write software which can take advantage of recent hardware developments (multicore, cloud) without compromising in its abstraction levels.

China wordt steeds assertiever in zijn relaties met andere landen, maar achter dit beeld gaat een opmerkelijk diverse maatschappij en politieke realiteit schuil die tal van aanknopingspunten biedt voor samenwerking en verdere integratie van China in de wereld. In China een gids voor de 21e eeuw past…

This thesis investigates opinion dynamics on random graphs through the lens of the voter model, a classical interacting particle system used to describe how consensus emerges in networks.

On 19 September 2023 Tabitha Speelman successfully defended a doctoral thesis and graduated.

Dementia is a progressive disease, diagnosed at a relatively late stage when intervention may not be effective. Aim of the research is to study scans of brain networks to help discover the early network changes related to dementia. Early diagnosis may benefit effectiveness of future treatment.

Dynamical systems describe the evolution of objects in a space over time and may be used to model physical phenomena. Due to this, much research is dedicated to understanding the mathematics of dynamical systems.

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

The development process of any software has become extremely important not just in the IT industry, but in almost every business or domain of research.

Constitutional and administrative law covers a broad area of law. It provides the rules with which issues in society can be solved by government authorities.

Examine and experience the material features and characteristic appearances of medieval manuscripts, annotated books, prints, drawings, photographic albums and much more, in various settings.

The conquest by Rome brought profound changes to large parts of Europe. Unprecedented infrastructural works were created, towns sprang up, a ribbon of fortresses was laid out along the frontiers.

Both play and politics have the potential to create worlds in which new rules apply, meanings are created, and possibilities emerge for collaboration, strategy and creative solutions. In this sense, play and politics have always been very much alike. But what happens to this kinship in a post-digital…

This thesis consists of two main parts. The first part (Chapters 2 and 3) deals with a class of Markov process called Quasi-Skipfree (QSF) processes.
