This study aims to examine how South Korea (hereafter, Korea) and Japan, two neighboring countries in Northeast Asia, have been responding to and mitigating the spread of COVID-19.

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.

How are contemporary art practices from Southeast Asia negotiating notions of art and tradition?

This doctoral thesis comprises four studies on the content and structure of physics teachers’ belief systems about teaching and learning physics in secondary education in the Netherlands.

A framework for prospective/ex-ante life cycle assessment (LCA) and ecological risk assessment (ERA) of emerging technologies is developed and applied to a case study of III-V/silicon photovoltaic panels.

Light-Harvesting Complex II (LHCII) is responsible for light absorption and excitation energy transfer in plants and photosynthetic algae, while in high light it undergoes conformational changes by which it quenches excitations to prevent photodamage.

Including modelling as part of software development appears to have various benefits.

On the largest scale, the Universe resembles a cosmic spiderweb. Most galaxies coexist in small groups within the threads of this web. At the nodes of the threads are enormous groups of galaxies forming the largest structures in the universe still held together by gravity: clusters of galaxies.

This project aims to investigate the underlying (neurocognitive) linguistic processes of ellipsis resolution, particularly gapping.

Tin electrodeposition applications have rapidly evolved in the past 25 years.

On the 16th of June Patrtick Harrison successfully defended a doctoral thesis and graduated.

The starting hypothesis of the project is that secrecy is not always inimical to democratic governance as conventional wisdom has it.

What are 'defects' and mechanical properties of mosaics of different shapes of tiles?

On October 9th, Peter Alexander Kerkhof succesfully defended his doctoral thesis and graduated. The Leiden University Centre for Linguistics congratulates Peter Alexander on this great result.

Smart algorithms and powerful processors are just as essential for astronomy as big telescopes. Astronomers at Leiden University therefore constantly operate at the interface between astronomy and data science.

In Migration and Membership Regimes editors Ulbe Bosma, Gijs Kessler and Leo Lucassen bring together ten essays in an analytical framework which looks beyond the Transatlantic migration of the nineteenth and twentieth centuries in a deliberate attempt to incorporate the experience of earlier periods…

We are developing the conceptual framework, which is new to this taxonomic group, and evaluate the current state of the art with respect to all critical parameters and transfer functions for a fully developed Population Consequences of Acoustic Disturbance (PCAD) model.

This study by artist Jonas Staal explores the development of propaganda art from the 20th to the 21st century.

The Mycenaean civilization of ancient Greek times offers enormous potential for useful information: from innovative construction methods to ways of handling crisis situations as a society. Archaeologist Ann Brysbaert and her team analyse Mycenaean construction processes in the ERC Consolidator project…

A functional study of chert artefacts from preceramic sites in Colombia (2002)

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

Cryogenic electron microscopy (cryo-EM) is a powerful technique used to visualize the inside of cells and to study specific protein complexes. Within this thesis, I describe the use of various cryo-EM techniques to gain insight into the structural changes of the human pathogen, Vibrio cholerae, as it…

Materials balances have been used in the recent past for the analysis of substance oriented environmental problems and the formulation of measures for environmental policy. In this study an integrated tool, based on the materials balance principle, has been developed for the analysis of both environmental…

Current status and future prospects

This work represents the final results of several years of research within the Maya region. It deals with the relations between architecture and urbanism with landscape and astronomy.

Galaxies form and live inside dark matter haloes. As a consequence, they are exposed to the tidal fields generated by the surrounding matter distribution: this imprints a preferential direction to the galaxy shapes, which leads to a coherent alignment on physically close galaxies, called intrinsic a…
