Artin L-functions associated to continuous representations of the absolute Galois group G_K of a global field K capture a lot of information about G_K as well as arithmetic properties of K.

Can SMILE, our multi-component intervention, which combines cognitive-behavioural therapy for insomnia, mindfulness, stress, and lifestyle components, improve sleep quality? Can it also improve mood and quality of life and prevent depression and anxiety in the long term?

This section features online articles by or about the team members of the Food Citizens? project.

Corporeality, intimately bound to the notion of space, to the diffuse border that connects, entangles, and fuses an inside and an outside, is understood in this book as a space which puts the individual at stake as a war machine that, in its fight for a form of life, redefines political territories.

An interdisciplinary cultural analysis of how the Hindustani double migration informs contemporary processes of identification and problematises the juxtaposition of tradition and modernity.

This thesis examines the complexity of legislative decisions within the EU, with a specific focus on the Council of the EU.

Heterogeneous catalysis is one of the fundamental processes of modern life, being common in industrial refinery and hydrogen vehicles, all the way to the living cell. The dissociation of H2 on Cu(111) is an important benchmark system for studying heterogeneous catalysis, with a large and varied amount…

In the spirit of 'unity in diversity', our objective is to promote insight into and appreciation for the wonder that the same physical laws and mathematical concepts apply to the whole of nature, from the largest to the smallest energy and length scales. We strive for the application of abstract theoretical…

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

Bringing the theoretical world of mathematics and computer science to more applied research areas. That is what Daan Pelt, assistant professor at the Leiden Institute of Advanced Computer Science (LIACS) is trying to achieve with the methods he is developing as a solution to challenges in image proc…

A look into the political history of collecting and the collections of Andean mummies in Western European museums from 1830-1930 through archaeology and paleoimaging.

How effective is eye movement desensitization and reprocessing therapy in targeting epilepsy-related anxiety?

Primary Objective: The primary aim of the proposed RCT is to evaluate whether LF-TLP in blended form as an indicated prevention for anxiety complaints is more (cost-) effective than TAU according to the NHG guideline Anxiety. We hypothesize that in comparison to TAU, LF-TLP will result in a significantly…
