One of the key limitations of the direct imaging of exoplanets at small angular separations are quasi-static speckles that originate from evolving non-common path aberrations (NCPA) to which the primary adaptive optics system is inherently blind. The main focus of this thesis is the development and…

Between the early thirteenth and early sixteenth centuries CE, the Sultanate of Cairo affected the balances of power elites across and beyond the regions of Egypt, Syria and the Eastern Mediterranean. Modern historiography has for a long time been determined by the idea of this sultanate as a highly…

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

Marokko en Nederland zijn nauw met elkaar verbonden. De aanwezigheid van een gemeenschap van Nederlanders met Marokkaanse wortels past binnen een gedeelde geschiedenis van vier eeuwen maatschappelijke en academische uitwisselingen. Als instelling die midden in de Marokkaanse maatschappij en het universitaire…

Join-in courses zijn MA-cursussen over middeleeuwse onderwerpen gegeven binnen vastgestelde MA-programma's van de zes deelnemende universiteiten van de Onderzoekschool. Op aanvraag zijn deze vakken toegankelijk voor studenten van andere (Nederlandse) universiteiten. De cursusbelasting en het aantal…

Onze deskundige coaches doen hun beste speechtips van de hand in deze korte video's. Leerlingen kunnen deze adviezen meteen inzetten in de Max Havelaar-lessenserie en docenten kunnen de tips gebruiken in hun eigen lessen over het gesproken woord.

De vluchtelingenstroom in Europa vraagt om effectieve maatregelen. Leidse onderzoekers toetsen of deze maatregelen legaal zijn en houden beleidsmakers een spiegel voor.

This dissertation is an experimental study of laser-generated, atmospheric pressure, transient toroidal helium plasmas.

Whilst government’s ability to design ‘context-specific’ regional innovation policy is generally assumed to depend on the region’s decision-making power, the aim of this study is to investigate how regional government matters. In order to open up the black box of policy design, the study develops a…

This thesis investigates opinion dynamics on random graphs through the lens of the voter model, a classical interacting particle system used to describe how consensus emerges in networks.

In this thesis we study bistable reaction-diffusion equations on lattice domains.

Enkele keren per jaar organiseert het Europa Instituut een ‘Meet the Author’ bijeenkomst. In het kader van deze nieuwe lezingenreeks komen externe academici naar Leiden om te spreken over een recente publicatie. ‘Meet the Author’ bijeenkomsten vangen aan met een gesprek tussen een lid van het Europa…

Developing new medicines is one of modern science's most significant hurdles, a process marked by high costs, long timelines, and frequent failures of promising candidates.

In most applications, electrocatalysts exhibit a large surface area to volume ratio, for example using nanoparticles.

If X is a locally compact Hausdorff space, then a representation of the complex C* algebra C_0(X) on a Hilbert space $H$ is given by a spectral measure that takes its values in the orthogonal projections on $H$.

Galaxy intrinsic alignments induce a major astrophysical contamination to weak gravitational lensing measurements and need to be modelled and mitigated when extracting cosmological information from such measurements.

Dit boek is de hoognodige herziening van ons begrip over publieke diplomatie. Het wil nieuwe manieren van denken stimuleren over wat wel een van de meest opmerkelijke recente ontwikkelingen genoemd kan worden in de diplomatieke praktijk. Een ontwikkeling die zowel mensen uit de praktijk als academici…

Constraint multi-objective optimization with a limited budget for function evaluations is challenging. This thesis tackles this problem by proposing new optimization algorithms. These algorithms are applied on holistic ship design problems. This helps naval architects balance objectives like cost, efficiency,…

The elementary excitations of magnets are called spin waves, and their corresponding quasi-particles are known as magnons. The rapidly growing field of Magnonics aims at using them as information carriers in a new generation of electronic devices, (almost) free of electric currents.

We find ourselves in an era of transition, not just towards a more computing- and data-driven society but also away from unsustainable fossil fuels as an energy source.

Metals surfaces form a group of effective catalysts for the reaction of small molecules such as hydrogen (H2).

Hot astrophysical plasma is ubiquitous in the Universe, from comets in our Solar system to the largest scale structures -- the cosmic web filaments. These hot plasmas, with the temperature of a few millions of degrees, are often observed in the X-ray wavelength range.

This thesis discusses the physical and chemical processes than influence the composition of forming planets.

Over several decades, a variety of computational methods for drug discovery have been proposed and applied in practice. With the accumulation of data and the development of machine learning methods, computational drug design methods have gradually shifted to a new paradigm, i.e. deep learning methods…
