The intracluster medium (ICM) is a hot, tenuous and X-ray emitting gas that pervades galaxy clusters.

Patterned detectors are an existing technology that can be found in almost all color cameras.

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…

The work presented in this thesis is based on ALMA surveys of protoplanetary disks in three star-forming regions: Lupus, OMC-2, and NGC 2024.

For optimization problems, it is often unclear how to choose the most appropriate optimization algorithm. As such, rigorous benchmarking practices are critical to ensure we can gain as much insight into the strengths and weaknesses of these types of algorithms.

Prematurely born neonates require, amongst others, pharmaceutical therapy. Dosing guidelines for these therapies are often based on data from term born neonates or older infants, while these are not necessarily similar to prematurely born neonates.

Over the past years it has been discovered that the population of extra-solar planets is large and diverse.

This thesis explores how electron paramagnetic resonance (EPR) spectroscopy can be used to investigate key biochemical processes.

The investigations described in this thesis lay out strategies aimed at advancing antibiotic research and development. The examples presented revolve around two main approaches: understanding drug-target interactions and target identification.

What physics controls the properties of quantum matter, such as how electrons flow inside high-temperature superconductors? This question has captivated the physics community and industry for decades, in part due to the great technological potential such materials have, but also because they have resisted…

IoT technology poses serval opportunities to supply chains. This thesis employs grey correlation and forecasting models, system dynamics, agent-based modeling, and ex-ante LCA to investigate and quantify the opportunities and risks of IoT-enabled sustainable supply chain operations from both industrial…

In this course, you will explore the organs involved in our food digestion and discover the common causes of abdominal and pelvic pain. The latest graphics and animations will give you new insights and understandings of this part of the body.

De gebouwen van de Faculteit Geesteswetenschappen in de binnenstad van Leiden worden één voor één aangepakt. Na de gerenoveerde gebouwen P.J. Veth, Arsenaal en Herta Mohr, wordt nu gewerkt aan het ontwerp voor het gebouw Aleida Nijland (voorheen Matthias de Vrieshof / Cluster Noord).

Effective policy-making requires understanding what truly causes a problem. Only then can policymakers develop targeted interventions that achieve desired outcomes.

De Universiteit Leiden bouwt aan haar toekomst in Leiden. Daarom investeert de universiteit de komende jaren ruim 100 miljoen euro in de vernieuwing van de gebouwen van de Faculteit Geesteswetenschappen, aan de Witte Singel en de Doelenzijde. Met deze nieuwe Humanities Campus, nauw verbonden met…

In this thesis, we consider various (electro)chemical phenomena at surfaces and nanoparticles and their underlying atomistic processes, which we studied using first-principles methods such as density functional theory.

De Universiteit Leiden werkt aan een groene, circulaire campus, met een forse energiereductie in 2050 als doel, zoals uitgewerkt in de in 2022 verschenen Routekaart energietransitie gebouwen.

Nanoparticles can be used as delivery systems for both small molecules and macromolecules such as proteins, peptides or oligonucleotides. This thesis focuses on the use of liposomes, nanometric vesicles formed by a lipid bilayer enclosing an aqueous core. Liposomes are highly versatile delivery syst…

In this thesis, the role of mast cells in atherosclerosis and novel therapeutic strategies to inhibit atherosclerosis progression are discussed. The first part of the thesis specifically focuses on the relation between mast cells and advanced human atherosclerotic plaque characteristics.

Classical statistical methods, such as p-values, are difficult for researchers to apply correctly. They for example do not allow drawing conclusions from a study early, or for extending a study with extra research groups that want to make their data available later.

Artificial intelligence algorithms govern in subtle, yet fundamental ways, the way we live and are transforming our societies. The promise of efficient, low‐cost or ‘neutral’ solutions harnessing the potential of big data has led public bodies to adopt algorithmic systems in the provision of public…

Irene Khan, expert op het gebied van mensenrechten, werpt een aantal vragen op: Wat kan men verstaan onder een ‘Culture of Justice’? Wie bepaalt wat 'Justice' is? Hoe realistisch is de bevordering van ‘Rule of Law’ en ‘Justice’ in landen waar sprake is van ernstige conflictsituaties en armoede?

A single self-assembled semiconductor quantum dot in a high-finesse optical microcavity - the subject of this thesis - is an interesting quantum-mechanical system for future quantum applications. For instance, this system allows trapping of an extra electron and thus can serve as a spin quantum memory,…

Het Leiden Bio Science Park (LBSP) is het grootste innovatiedistrict van Nederland op het gebied van Life Sciences & Health. De clustering van hoogwaardig onderwijs, onderzoek, zorg en bedrijfsleven trekt studenten, wetenschappers en ondernemers vanuit de hele wereld naar kennisstad Leiden.

Den Haag is, naast Leiden, de tweede moederstad van de Universiteit Leiden.

Plants and soils from natural ecosystems harbor great diversity of soil microorganisms, which could potentially contribute to the sustainability of horticulture. The knowledge about using wild plant species and soil from natural ecosystem to improve the crop health will advance the application of ecological…

The thesis explores how interstellar chemistry evolves as a function of time and changing physical architectures during the formation of stars.

The subject of this thesis, ‘Approach to Markov Operators on Spaces of Measures by Means of Equicontinuity’, combines an analytical and probabilistic approach to Markov operators.

The aim of this thesis was to study phage infection in Streptomyces, focused on cell wall-deficient cells. Bacteriophages (or phages in short) attach to the cell wall of bacteria after which they replicate and lyse the host cell.

The origin and evolution of galaxies are closely tied to the cyclic feedback processes between stars and the interstellar medium (ISM).
