The main aim of this project is to reveal and unravel the invisible histories of the UN, transcending the dominant Western perspective to recover the historical agency of Global South actors. The research will investigate how the UN has both facilitated and limited their role in shaping global order…

In het voorjaarssemester biedt het NIMAR universitaire en hbo-studenten twee engelstalige tracks van 30 EC. Bij beide tracks ligt de focus op het bevorderen van taal- en linguïstische vaardigheden, maar de tracks bieden ook een diepgaande kennismaking met de Marokkaanse cultuur en samenleving.

The aims of the project are to: further clarify 'inhibition by safety'; explore and describe all possible sagety factors, with a special focus on the primary human safety source: social connectedness; reviewing prolonged stress responses without stressors.

This thesis describes the synthesis, analysis of various tetrazine bearing compounds and use in bioorthogonal chemistry.

Corruption, integrity (or a lack thereof…) and public values are near omnipresent elements in public administration and politics of all times. Cases of corrupt public officials and politicians continuously emerge. Strangely enough, however, it often remains unknown what actually occurred, how something…

African oral literatures, new media and technologies: challenges for research and documentation

The research presented in this thesis concerns one of the most important questions in software engineering of our time: how can we make sure that software is free from memory safety bugs?

Het LIACS organiseert verschillende lezingenseries, zoals het LCN2 Seminars en de SAILS Lunch Time-seminars.

Protoplanetary disks are the gas and dust environments where planetary systems form around young stars. Using observations from the Atacama Large Millimeter/submillimeter Array (ALMA) this thesis analyses the gaseous molecular reservoir, using multiple tracers to resolve the 3D structure of protoplanetary…

Denk je schaamte om en maak het je kracht.

Heterogeneous catalyzed processes are highly significant to the chemical industry. Dissociative chemisorption (DC) of molecules on surfaces is always considered as a step with a high degree of rate control for heterogeneous catalysis.

Programma's die de symptomen van sociale angst bij kinderen willen verminderen, omvatten doorgaans meerdere onderdelen, zoals blootstelling en mentale herstructurering. Het is onbekend of afzonderlijke onderdelen positieve effecten opleveren bij kinderen of dat een combinatie van onderdelen nodig is…

This thesis focused on the exploration of monolayer graphene as a membrane in direct methanol fuel cell (DMFC) applications, with improvements achieved through plasma exposure or damage- free chemical functionalization.

The work in this thesis has been focused on two subjects. The first is the assembly of alginate oligosaccharides and the generation of building blocks for the enzymatic synthesis of alginate, and the second is the total synthesis of large fragments of the zwitterionic SP1 polysaccharide.

Galaxies form and evolve through close interaction with their surroundings. As a result, the heavy elements ('metals') that are synthesized in stars, are found both inside and outside galaxies.

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

We showed that constitutive and inducible chemical and morphological defenses against Western flower thrips differ between tomato and chrysanthemum plants.

Errors are everywhere, and mechanical failures are especially common: buckled grain silos and cracked support columns are, justly, seen as an issue to be avoided.

This dissertation contains four works during my PhD. Different biomaterials have been designed based on coiled-coil peptides. These biomaterials have a range of applications, inclusing drug delivery, cell sorting to cell-cell fusion.

Nature uses a special class of histone proteins, histone variants, to modulate the properties of chromatin at defined genomic locations.

Self-assembly offers a promising route to create complex structures and materials using simple building blocks. Through, colloidal self-assembly, we can understand the governing principles of the self-assembly process and unlock its potential in diverse applications in materials science, photonics and…

Radio jets are important to the evoultion of galaxies. However, it is still not fully understood how a radio jet can be triggered.

In this thesis, we developed new ways to use a technique called electroextraction (EE) to extract charged molecules from one liquid into another using an electric field.

Carbohydrates, alongside proteins and nucleic acids, constitute a crucial and versatile family of biomolecules present in all life forms. They manifest as monosaccharides, oligosaccharides, and polysaccharides, covalently bonded to proteins and fats. Carbohydrates are integral to plant and arthropod…

The research group Science Communication and Society aims to understand how science communication works to improve the interaction between science and society. Central themes are ‘Bridging the gap between experts and the general public’ and ‘Evaluating Science Communication’.

This thesis describes the implementation and on-sky demonstration of high-resolution integral-field spectroscopy for extreme adaptive optics systems that are used to find and characterize exoplanets.

In this thesis, we aim to shed light on the diverse and often opposing roles of integrin α3β1 in cancer.

This thesis tackles the urgent challenge of antimicrobial resistance (AMR) through the design of novel antibacterial agents.

As part of the NWO-funded research project ‘The Multilingual Dynamics of the Literary Culture of Medieval Flanders, c. 1200- c. 1500’, we invite proposals for 20 minute papers addressing any aspect of medieval literature and literary culture. We welcome proposals from scholars at all career stages—and…

Een academische studie of carrière is een flinke uitdaging als je doof bent. Al helemaal in Afrika, waar in veel landen geen eens middelbare dovenscholen zijn. Een team Leidse wetenschappers organiseert in Ghana de eerste summer school voor én door dove academici op het Afrikaanse continent. We spraken…

This thesis advances automata learning, a key area in computer science, with applications in software verification, biological analysis, and autonomous technologies. It explores three main themes: first, it introduces a passive learning algorithm for generating compact probabilistic models from positive…

My PhD research is devoted to studies of the conjectural cluster-algebraic symmetry in the theory of topological string, which is the simplest, however already non-trivial sector in the theory of string.

Het fragmentarische is overal: we komen fragmenten tegen op sociale media (TikTok, Twitter), in persoonlijke herinneringen uit onze kindertijd en in tradities uit ons cultureel erfgoed.

Het Research Lab for the Study of Heritage Languages of the Netherlands (HERLING) is een platform voor onderzoek naar erfgoedtalen die in Nederland worden gesproken, met een focus op Turks, Bahasa Indonesia, Spaans, Papiamento, Berbers, Arabisch en Duits. HERLING wil een brug slaan tussen wetenschappelijk…
