Learning a programming language is challenging. Even one of the first –but crucial– concepts to learn, variables, is hard to grasp. Variables can represent different roles and functions within a code and need to be named appropriately to support code comprehension and debugging.

Our recent excavations have focused on the more recent New Kingdom/Late Period (ca. 1500-332 BCE) material.

Medewerkers en studenten van Leiden University College (LUC) werken in Den Haag samen met maatschappelijke partners via onderzoek, onderwijs, stages en vrijwilligerswerk, waardoor er sterke banden ontstaan die ook na het afstuderen blijven bestaan.

Symposium

In de 19e eeuw werden Oudengelse gedichten geclaimd als cultureel erfgoed door verschillende niet-Engelssprekende naties, waaronder Scandinaviërs, Duitsers en Nederlanders. Deze concurrerende nationalistische, culturele toe-eigeningen gebeurden tegen de achtergrond van een groeiende interesse in de…

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. Brieven waren een snelle, efficiënte manier om inzichten, gegevens en ontdekkingen te delen. Correspondentie…

Het P.J. Cosijn Research Fellowship is een initiatief om veelbelovende Research MA-studenten van de Universiteit Leiden met interesse in Angelsaksische studies de kans te geven onderzoek te doen naar Oudengelse taal- en letterkunde. De Cosijn Fellowships zijn onderdeel van het door ERC gefinancierde…

Enzymes are innately sensitive to changes in the amino acid sequence, which largely constrains their evolutionary potential, i.e., evolvability. This evolutionary burden can be alleviated in the presence of stabilizing mutations, which increase the buffering capacity of enzymes to tolerate mutations…

Multiple stars, that is two or more stars composing a gravitationally bound system, are common in the universe.

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

Outflows are crucially important for the gas budget and evolution of luminous star-forming galaxies and AGNs, with observed mass outflow rates of the same order as the star formation rate. Greater star formation and black hole growth lead to more intense feedback and outflows, resulting in self-regulated…

Parkinson's disease is the second most common neurodegenerative disease in the world. One of its symptoms is the loss of dopaminergic neurons in the substantia nigra pars compacta.

In this dissertation iron-based homogeneous catalysts were synthesized, characterized and investigated for water oxidation activity.

Utilizing the polymeric platform of polypept(o)ides, this thesis describes synthesis and investigation of novel triblock copolymers to obtain carrier systems with multiple compartments for efficient siRNA delivery. Although the individual microstructure of nanoparticles differs depending on the polymeric…

The increasing competition in the automotive industry requires the tailored, swift development of technologically sophisticated vehicles. Therefore, the computationally expensive state-of-the-art simulation technologies are combined with optimization algorithms. An example of a real-world optimization…

All life on earth contains DNA, which is used to store biological information. Organisms compact their DNA in order for it to fit inside their cell(s).

Three major cosmology-focused missions are planned for the next decade: the Euclid space telescope, the Vera C. Rubin Observatory in Chile, and the Nancy Grace Roman Space Telescope.

The overarching goal of this thesis is to set the foundations, but also make the first essential steps towards establishing a comprehensive, mesoscopic, hydrodynamic theory of epithelial tissues. The stage is set by an exhaustive study of topological defects in passive p-atic liquid crystals, singularities…
