In de 19e eeuw eigenden verschillende Europese landen zich Oudengelse gedichten toe als hun erfgoed. Dit onderzoek laat zien hoe die internationale belangstelling de basis legde voor de Oudengelse studies.

In een tijdperk vóór GoogleDocs en LinkedIn vertrouwden 19e-eeuwse wetenschappers op het schrijven van brieven voor samenwerking, peer-feedback en het opbouwen en onderhouden van academische netwerken.

Security is key to survival for any living organism: life is full of perils and threats, both physically, environmentally, and societally. Security challenges such as terrorism, natural disasters, and cybercrime rank among the most pressing issues of our time, affecting the security and safety of millions…

The bacterial cell wall is a nearly universal structure that offers protection and gives the cell its shape. However, environmental stressors, such as cell wall-targeting antibiotics and hyperosmotic conditions, can induce bacteria to shift to a wall-deficient state. It is unknown whether the lack of…

To study how planetary systems come into existence we study much younger systems still in formation.

This work describes the use of click-to-release chemistry to get spatiotemporal control over immunocytokine activity. Until now, immunocytokines (cytokines coupled to a tumor-targeting-moiety) remained active throughout the body, being able to bind their respective receptors, causing mild to severe…

This dissertation explores how Large Language Models (LLMs) can effectively and responsibly contribute to complex decision-making processes. By combining AI and human intelligence, Hybrid Intelligence (HI) emerges, allowing the strengths of both humans and machines to be utilized.

This thesis is about augmented reality (AR). AR is commonly considered a technology that integrates virtual images into a user’s view of the real world.

While ecosystems have concrete benefits for human society, these benefits are typically overlooked in decision-making.

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

Healthy aging is one of the prime goals in today's society and atherosclerosis is among the greatest causes of morbidity in elderly. Cardiovascular disease patients receiving treatment are often of advanced aged and have an aged immune system, which limits translating experimental findings to the pa…

In this work, I explore the creation of new methods that optimize simulations of the gravitational N-body problem. Specifically, I take advantage of the recent popularity of Machine Learning methods to find tools that can suit this problem.

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…

Hydrogen fuel cells are expected to be pivotal in the energetic transition towards renewable energy sources such as solar and wind power. However, their industrial scalability is severely hindered by the high cost and degradation rate of platinum catalysts, one of their key components. Addressing this…

The research aims to explore the evolutionary adaptability of enzymes and the impact of temperature on protein evolution pathways, using M. tuberculosis β-lactamase BlaC as the object of study. Enzymes inherently embody a delicate balance between activity and stability, and the acquisition of new enzymatic…

This thesis studies the geometry of representation varieties and character stacks. These are spaces parametrizing the representations of a finitely generated group, typically the fundamental group of a compact manifold, into an algebraic group G.

We consider the propagation of electrical signals through nerve fibres.

A tidal basin is an inland sea which is almost entirely enclosed by land and connected to the open sea by a tidal inlet. Through the tidal inlets interaction takes place between the tidal basin and the open sea.

The Copenhagen interpretation of quantum mechanics states that a measurement collapses a wavefunction onto an eigenstate of the corresponding measurement operator.

The field of exoplanet research is rapidly advancing through the development of new technology, observing techniques, and post-processing methods.

Assessing the risks of engineered nanomaterials (ENMs) solely on the basis of experimental assays is time-consuming, resource intensive, and constrained by ethical considerations (such as the principles of the 3Rs of animal testing). The adoption of computational toxicology in this field is a high p…

In dit project gebruiken we sociale netwerkanalyse om het gedrag van gebruikers op online fora en bijbehorende marktplaatsen in de tijd te analyseren.

Science is typically a patchwork of research contributions without much coordination. Especially in clinical trials, the follow-up studies that we do fail to be the most promising.

Het doel van het RAISE Onderzoek is om te onderzoeken hoe veerkrachtige mensen omgaan met stress. We kijken specifiek naar hoe belangrijke biologische systemen, zoals de HPA-as en het immuunsysteem, samenwerken met de hersenen en de sociale omgeving om veerkrachtig functioneren na moeilijkheden in de…

With the advent of multicore processors and data centers, computer hardware has become increasingly parallel, allowing one to run multiple pieces of software at the same time on different machines. Coordination of these pieces is best expressed in a coordination language as an explicit interaction protocol…

A key step in the synthesis of oligosaccharides and glycoconjugates is the formation of the glycosidic bond.

In multi/many-core System-on-Chips (SoCs), the performance is almost linearly scaling with the number of processing elements.

Elk jaar reikt het Leids Universitair Studentenplatform (LUS) de Leidse Onderwijsprijs uit.

Natuurkundestudent Barry van der Meer heeft woensdag de VWN/NWO studentenbeurs in ontvangst genomen. Deze beurs dekt de registratiekosten voor de World Conference of Science Journalists 2009, die van 30 juni t/m 2 juli in Londen gehouden zal worden.

The experiences of ethnic ‘Other’ females have – until recently – been widely overlooked in the study of sport. There continues to be a need to produce critical scholarship about ethnic 'Other' girls and women in sport and physical culture, in order to represent their complex, multifarious and dynamic…

De master History van de Universiteit Leiden heeft een sterk internationaal karakter en focust op Europese- en niet-Europese geschiedenis vanuit een globale context.

Hoe hebben de purana's, als oude verhalen en anonieme teksten, bijgedragen aan de religieuze en politieke cultuur van het Sanskriet-wereldrijk? En hoe hebben verschillende mensen en groepen bijgedragen aan de verspreiding en ontwikkeling van deze teksten door de tijd en over verschillende regio's he…

Er wordt vaak geclaimed—in zowel academische als populaire publicaties—dat blindegeleidehonden een moderne uitvinding zijn. Maar hulphonden bestonden ook tijdens de Middeleeuwen, zoals dit project aantoont.

Door de opkomst van nieuwe methodes en technologieën, zoals verbeterde DNA-analyse en big data, is het archeologisch onderzoek de afgelopen decennia ingrijpend veranderd. De onderzoekers van het departement Archaeological Sciences van de Faculteit Archeologie gebruiken de nieuwe wetenschappelijke kennis…

In 2005 groeven archeologen van de gemeente Leiden een 2700 jaar oude boomstamkano op. Deze boomstamkano wordt nu door wetenschappers van Material Culture Studies nagebouwd met behulp van replica's van ijzertijd-werktuigen. De wetenschappers willen zo onder meer beter inzicht krijgen in het bouwproc…
