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 consists of two parts, each of which considers a different research area related to random interval maps. In the first part we are interested in random interval maps that are critically intermittent.

The thesis mainly contributes to the characterization of Majorana fermions as they appear in the Condensed Matter context.

The main topic of this PhD thesis is the Arakelov ray class group of a number field, an algebraic object that contains both the ideal class group structure and the unit group structure.

The aim of this thesis is to present novel techniques for proving cryptographic schemes secure against quantum adversaries. Most results are within the context of an idealized model called the ‘quantum random-oracle model’.

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.

The transition period in which men become fathers might provide an important window of opportunity for parenting interventions that may produce long-term positive effects on paternal care and, consequently, child development. Existing prenatal programs traditionally focus on maternal and infant health…

Mathematician Oliver Nagy still vividly remembers the first time he learned about a random walk. ‘The lecturer told us to imagine a company of drunken students who wander in the streets. At each intersection, they would spin one of them around and all would go in the direction where he or she came to…

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…

Programs that aim to reduce symptoms of social anxiety in children generally include multiple components, such as exposure and cognitive restructuring. It is unknown if separate components yield positive intervention effects in children or whether a combination of components is required.

We found that, next to the effectiveness of the intervention, it’s also very likely that the intervention is cost-effective compared to attention only.

This dissertation consists of two parts, with the common theme

Plants and their pollinators form complex interaction networks. Within these networks, species differ widely in the number of species they interact with.

Principles of Environmental Sciences provides a comprehensive picture of the principles, concepts and methods that are applicable to problems originating from the interaction between the living and non-living environment and mankind. Both the analysis of such problems and the way solutions to environmental…

The project’s overall goal is to improve Indonesia’s environmental legal framework and its implementation by strengthening the regulatory capacity of the government, and by enhancing the capacity of CSOs and scholars to hold the government accountable for its regulatory performance.

How to reconstruct the middle parts (videlicet haute-contres, tailles and quintes) from French orchestral pieces, which survived only in their reduced forms (featuring primarely dessus and continuo), according to historical examples?

From 2 to 6 June 2014, Prof. dr. Frank den Hollander has provided 2 lectures during the workshop ‘Recent Models in Random Media’ at the Centre International de Rencontres Mathematique in Marseille (CIRM). This center facilitates workshops for mathematicians throughout the year.

Environmental Humanities is one of the LUCAS research themes, bringing together members of the three LUCAS clusters.

This research programme aims to increase the scientific understanding of how current and emerging anthropogenic threats affect biodiversity and ecosystem services to facilitate strategic management of natural resources. To this end, we address urgent challenges in relation to the mechanisms involved…

PhD candidates carry out a programme of independent research and additional (limited) course work, culminating in production of a PhD thesis in typically 4 years.

Leiden University is aware of its role in society and wants to create a green, healthy and inclusive campus and have a positive impact on the field of climate and circularity.

This systematic review of 68 English-language articles explores the roles of customary authorities in environmental governance in sub-Saharan Africa

In the absence of stringent and coordinated international action, States might seek alternatives to promote environmental protection unilaterally.

Natural resources are becoming increasingly scarce. If we want to maintain our current standard of living, we will need inventive solutions. The researchers at the Institute of Environmental Sciences (CML) share their thoughts on how to achieve a fully circular economy in which as little use as possible…

Research in the POD-group addresses all features of random phenomena – modelling, structuring, analysis, control, optimisation – and covers both fundamental and applied aspects.

This project aims to explore the environmental impact of early Roman expansion (4th/3rd century BC) through a program of dating and ecological sampling of traces of field systems (centuriations).

The state of our environment is a global concern. Despite an increasing awareness, setting internationally binding and ambitious commitments has proven to be a very difficult process. Can unilateral trade measures form an alternative and contribute to global environmental protection?

Scattering of light in the presence of nano-structured materials, i.e. with features in the order of the wavelength of the light or smaller, reveals details of how light interacts with matter at the nanoscale.

What is the best way to combine the environmental and economic data and how can we create an operational system to do so, thereby supporting the delivery of data to the Data centres on Products and Resources?

On 24 April, Feby Kartikasari defended the thesis 'Mining and environmental protection in Indonesia: regulatory pitfalls'. The doctoral research was supervised by Adriaan Bedner and Bernardo Ribeiro de Almeida.

To limit the effects of climate change, global average temperature since pre-industrial measurements are to be kept well below 2 °C preferably even at 1.5 °C.

The majority (80%) of e-waste generated globally are recycled informally in developing countries.

They were called 'annoying brats', the group of campaigning scientists who in 1978 founded what is now an internationally acclaimed ecological research institute. Their stories and those of the current staff of the Institute of Environmental Sciences are described in the book 'Forty years of Leiden…
