Het boek gaat in op de vraag: Hoe en waarom raken mensen betrokken bij het Europese 'homegrown jihadisme'?

The long-held desire - to link structure directly to function and to explain molecular mechanisms based on basic chemical or physical principles - is finally coming closer, satisfying not only our scientific curiosity but also offering new solutions to the many challenges in the field of health, energy…

In de media horen we veel verontrustend nieuws uit Afrika over vluchtelingen, aanslagen, ebola, hongersnood en corruptie. Maar Afrika is veel meer dan dat: het is een continent in transitie waar de ontwikkelingen in hoge snelheid elkaar opvolgen. Leidse Afrikanisten van verschillende wetenschappelijke…

De minor Creative Strategies for a Society in Change (CSSC) legt een verbinding tussen het verkrijgen van inzicht in creatieve maakprocessen en het verkennen van maatschappelijke problematieken die kenmerkend zijn voor onze tijd.

Surface acoustic waves (SAWs) are mechanical waves that travel along the surface of a material and find many applications in modern technologies due to the ease of excitation on piezoelectric substrates via interdigital transducers (IDTs).

Leidse wetenschappers en studenten bloggen en podcasten over onderzoek en onderwijs.

De staatsgreep in Niger krijgt veel media-aandacht. Hoogleraar Mirjam de Bruijn duidt de situatie in verschillende media.

On the largest scale, the Universe resembles a cosmic spiderweb. Most galaxies coexist in small groups within the threads of this web. At the nodes of the threads are enormous groups of galaxies forming the largest structures in the universe still held together by gravity: clusters of galaxies.

In this dissertation, we work towards an experiment in which we aim to bring a micrometer sized magnet at the tip of a soft cantilever into a superposition.

The stratum corneum is the outermost skin layer and consists of dead cells embedded in a lipid matrix.

This thesis pioneers diatom molecular identification and quantification through genome-scale methods, with four key aims: (i) reviewing DNA/RNA sequencing methods in aquatic biomonitoring to highlight their strengths and limitations;

n this PhD thesis, the recombination of different atomic lattices in stacked 2D materials such as twisted bilayer graphene is studied. Using the different possibilities of Low-Energy Electron Microscopy (LEEM), the domain forming between the two atomic layers with small differences is studied.

Humans can see the world through the eyes of other humans and imagine what they know, want, and intend. This competence is known as Theory of Mind.

In het oosten van Afrika dreigt een grote hongersnood, onder meer doordat de graanexport uit Oekraïne door de oorlog stopt. Bij ‘Met het oog op morgen’ legt hoogleraar Mirjam de Bruijn uit waarom de Russen toch niet algemeen worden gehaat in Afrika.

In this thesis, classes of strongly interacting quantum field theories, have been studied.

A novel mathematical model describes spatial-temporal drug distribution within one or more brain units, which are cubic representations of a piece of brain tissue with brain capillaries at the edges.

Kantorowicz onderzoekt hoe genderstereotypen de perceptie van leiderschapscompetentie beïnvloeden bij verschillende soorten crises.

This study seeks to analyse how job stress could be the result of performing administrative tasks

Vaak wordt gezegd dat een crisis iemands ware aard naar boven brengt. Het coronavirus stelt het multilaterale systeem op de proef. Politicoloog Gisela Hirschmann (Universiteit Leiden) maakt zich zorgen over de toekomst van internationale samenwerking.

In dit artikel onderzoeken Wout Broekema, Wouter Jong en Sara Perlstein het ontwerp en de beoordeling van crisisonderzoeken vanuit een leerperspectief.

De auteurs presenteren een benadering voor het achterhalen van de voorkeuren van de bevolking voor gebruik in de optionele wegingstap in de Levenscyclusanalyse (LCA).

Dit onderzoek presenteert een vijfstappenplan voor de ontwikkeling van een effectieve gedragsgerichte cyberveiligheidsstrategie.

In the current global context, there is a pressing need to address sustainable energy supplies to safeguard our Planet and its ecosystems. The choices made by human society have a significant impact on genetic evolution and climate.

Atherosclerosis is the most important underlying process that drives cardiovascular disease, and is characterized by an accumulation of cholesterol which triggers an inflammatory response in the vessel wall.

Pharmaceutical companies, governments and the general public have become increasingly aware that animal models used in drug testing lack vital aspects to serve as an accurate representation of human biology. As models of the human body should become more physiologically relevant, animal models no longer…

Supply risks are not new. But the aggravation of power conflicts on the international stage coupled with global shifts towards energy transition and digitalization has triggered the next supply risk research era.

In this thesis, we used genetically engineered mouse models and a variety of cell-culture based assays to identify genes and pathways that are involved in the development and treatment of invasive lobular carcinoma (ILC).

Het Instituut voor Geschiedenis feliciteert Mirjam de Bruijn met het verkrijgen van een VICI-subsidie voor het onderzoek 'Connecting in Times of Duress: Understanding Communication and Conflict in Middle Africa’s Mobile Margins.'

Understanding how galaxies form, interact, and evolve comes largely from comparing theory predictions with observational data. Numerical simulations of galaxies provide the most accurate approach to testing the theory, as they follow the non-linear evolution of gas and dark matter in great detail and…

Early time-resolved experiments by Frauenfelder on the ensemble of the kinetic rebinding of CO to myoglobin molecules resulted in a stretched exponential relaxa-tion due to a very large spread of the reaction rates of individual molecules.

Barrier function is the natural role of the skin. The lipid matrix present in the outermost layer of the skin, the stratum corneum is important for this function.

Arithmetic geometry concerns the number-theoretic properties of geometric objects defined by polynomials. Mathematicians are interested in the rational solutions to these geometric objects.

Neurodegenerative diseases pose a large medical and societal challenge. The etiology of these diseases is still poorly understood, which makes drug discovery for these diseases difficult.
