This thesis focuses on the study of transient and variable radio sources in the universe.

We show that Kirchhoff ’s law of conservation holds for non-commutative graph flows if and only if the graph is planar. We generalize the theory of (Euclidean) lattices to infinite dimension and consider the ring of algebraic integers as such a lattice.

The formation of stars and planets happens over multiple scales, which can interact. In particular, planet formation happens in the dense, complex environment of star forming regions.

Make more fluid: In condensed matter systems, electrons can acquire unusual properties from their interaction with the atomic lattice.

In unconventional high temperature superconductors, supercurrent vortices are known to spoil the Landau levels. In this thesis the emergence of Landau levels is studied in different types of superconductors: Weyl superconductors, and the Fu-Kane heterostructure.

Evolution acts via mutations in amino acid sequences. Substitution of essential amino acids leads to a nonfunctional protein. l.

This thesis examines silicon pore optics (SPO), a technology that exploits silicon wafers from the semiconductor industry to create extremely high quality X-ray optics, by studying its manufacturing process, applications, and prospects.

The outbreaks of AIDS and COVID-19 showed clearly how infectious viruses can influence people’s lives. Investigating the changes in the host metabolism may provide a paradigm shift to consider immune-metabolic interactions as therapeutic targets.

Extending our current arsenal of antibiotics is key to staying ahead in the arms race between humans and resistant bacteria.

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…

This thesis consists of three chapters. Each chapter is on a different subject. However, all three chapters address issues that arise in counting arithmetically interesting objects.

This thesis is an experimental study of the UV irradiation of the interstellar ice analogues, relevant for the different stages of the star and planet formation sequence.

This thesis consists of two subjects, that are both a consequence of radiation pressure.

This Thesis shows discoveries in non-linear astrochemical kinetics as well as a deeper analysis of dark clouds chemistry.

With the rise of multi-drug resistant bacterial pathogens, the possibility of a post-antibiotic world is quickly becoming reality.

Prof. dr. Bernhard Hommel heeft een Advanced Grant ontvangen van de European Research Council (ERC). Met deze beurs van 2,5 miljoen euro gaat de cognitief psycholoog vijf jaar lang onderzoek doen naar 'metacontrole'; de manier waarop wij bepalen hoe groot de invloed van onze doelen is op ons daadwerkelijke…

Drie Leidse wetenschappers ontvangen een ERC Advanced Grant. Daarmee doen zij de komende vijf jaar onderzoek naar exoplaneten, de vrije wil en deeltjesfysica.

Sinds 2009 behaalden 91 kandidaten hun doctoraat in Creative en Performing Arts. Op deze pagina een overzicht van ACPA's alumni.

The "Cognitive Turn" and the Middle Ages - There is an increasing interest in the cognitive sciences and how knowledge from this area influences literary studies, history, art history, and studies in material culture. This meeting seeks to discuss the possibilities, but also the limitations of incorporating…

The NWO-funded Vidi project “American foreign policy and liberalism” challenges the idea that the United States has created and sustained a “liberal international order” since World War II. It instead explores the ways in which illiberal ideologies – such as those underpinning racial hierarchy at home…

Aangezien jeuk en pijn zeer belastend kunnen zijn, vooral wanneer mensen chronisch aan (een van) deze symptomen lijden, is het belangrijk te weten door welke factoren deze gewaarwordingen worden beïnvloed. Het wordt steeds duidelijker dat psychologische factoren een belangrijke rol spelen bij het ervaren…

A recent study on reintroduced tigers in Panna Tiger Reserve in India reveals that risks from tigers increased more because of human behaviour and people's livestock husbandry practices.

Het belangrijkste doel van dit onderzoek is om de steden van het Romeinse Nabije Oosten in de keizertijd in kaart te brengen, met een focus op locatie, stadsgrootte en stedelijke kenmerken, om de vorm van het stedelijke systeem en de niveaus van integratie te bestuderen.

Because thin systems can deform along the thickness with relative ease, the interplay between surface mechanics and geometry plays a fundamental role in sculpting their three-dimensional shape.

There is a need for alternative methods to replace, reduce and refine (3R) animal experimentation. Combining experimental data from high-throughput in vitro studies with in silico modeling is a promising approach to unravel the effect of chemicals on living cells and to gain a better understanding of…

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…

Automated Machine Learning (AutoML) is widely used to automatically build a suitable practical Machine Learning (ML) model for an arbitrary real-world problem, reducing the effort of practitioners in the ML development cycle for real-world applications. Optimization is a key part of a typical AutoML…

In the traditional theory of linear elasticity, superposition dictates that the response of a material does not depend on the sequence of the applied mechanical actuations.

The Sun and all the stars in the night sky reside in the Milky Way galaxy. In the at-rest reference frame of the Galaxy, typical stars travel with velocities of about 100-200 kilometres per second.
