On 29 June May 2022 Yujing Tan successfully defended a doctoral thesis and graduated.

This thesis is divided into two parts. In Part I we study metastability properties of queue-based random-access protocols for wireless networks. The network is modeledas a bipartite graph whose edges represent interference constraints. In Part II we study spectra of inhomogeneous Erdős-Rényi random…

This dissertation presents four separate chapters, all striving towards the same goal: to understand dynamic phenomena occurring in dynamic networks and to explore the emergence of equilibrium in a broad sense.

Central Limit Theorem associated to a particular case of ergodic total automorphisms. Finally, Chapter 6 proves that the isoperiodic foliation is connected for a meromorphic differential with three poles on a torus.

This dissertation concerns the role of analogy in Kant’s “Critique of the Teleological Power of Judgment”, especially the role of analogy for the formation of the concept of a natural end (Naturzweck). A ‘natural end’ is a ‘regulative concept’ of the reflective power of judgment, that is, a heuristic…

Assesses the importance of Merleau-Ponty to current and ongoing concerns in contemporary philosophy.

The International Financial Law programme of Leiden University looks at financial law from multiple perspectives to illustrate the links between law, economics and ethics.

The parabolic Anderson model (PAM), which is the Cauchy problem for the heat equation with random potential. The PAM is a mathematical model that describes how mass (i.e. matter or energy) flows in a medium in the presence of a field of sources and sinks.

This research team is concerned with the measurement and modelling of behaviour, cognition, and unobserved traits (e.g., latent variables, missing data). Central aims include the distillation of a complex set of features into lower-dimensional representations (e.g., factor analysis, IRT), determining…

How do we address the pressing challenges posed by large-scale networks?

The focus of this thesis is on the technical methods which help promote the movement towards Trustworthy AI, specifically within the Inspectorate of the Netherlands.

Perfect for use at advanced undergraduate and graduate level, this is the first text to offer students a unified narrative regarding the place of the body in Western thinking. The book investigates the ways in which the fact of human embodiment makes the notion of ambiguity central to all major areas…

Transport inspectorates are looking for novel methods to identify dangerous behavior, ultimately to reduce risks associated to the movements of people and goods. We explore a data-driven approach to arrive at smart inspections of vehicles.

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.

Porosity between Politics and the Economy addresses the relationships between politics and the economy in deeply original ways. It is a book motivated by a sense of urgency aroused by both the failure of modern capitalism and the environmental crisis.

In this 3-volume set of primary sources, Lionel Laborie and Ariel Hessayon bring together a wide range of vital sources for the study of prophecy in the early modern world. This meticulously edited collection includes rare material and fascinating manuscripts published in English for the first time.

Rising geopolitical tensions are causing states and national elites to innovate their use of the past for present-day political ends. This is certainly true for the People’s Republic of China, which celebrated its 75th anniversary in 2024 amid mounting superpower rivalry, ideological tensions with the…

The Department of Company Law and Financial Law conducts research in areas including the law of legal entities and corporations, the law of financial obligations and liability, corporate governance, sustainability, national and EU financial supervision, mergers and acquisitions, insolvency law, and…

Throughout the history of computer science, a major challenge has been how to assert that software is free of bugs and works as intended. Software bugs can lead to serious negative impacts on any software system. Throughout the main body of the thesis, we implemented a series of studies on exploring…

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…

Organisms often need to adapt more efficiently and devise new strategies for surviving difficult ecological circumstances.

Freshwater and brackish water ecosystems are arguably the most vulnerable ecosystems on earth, due to concentrated human developments in and around them. The Pontocaspian (PC) region located at the border of Europe and Asia contains a variety of brackish water ecosystems and unique inhabitants, known…

Gibbs measures, as used in Statistical Mechanics, have a definition that is remarkably similar to the definition ofg-measures, used in dynamical systems.

This dissertation is organised into three parts, each addressing a distinct research area related to Gibbs measures.

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

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…

Stochastic resetting is simple enough to be approached analytically, yet modifies stochastic processes in a non-trivial way.
