On 11 October, the roundtable entitled ‘Academic Freedom – Theoretical Perspectives’ took place at Leiden University's Academy Building. This event was organised as part of the Vidi research project entitled 'The EU fundamental right to 'freedom of the art and sciences': exploring the limits on the…

A Spanish translation of Herman Paul’s 'Key Issues in Historical Theory' has appeared under the title 'La llamada del pasado: claves de la teoría de la historia'.

The work in this thesis demonstrates how to obtain an atomic-scale picture of a diverse set of complex surface structures observed using STM, under disparate conditions.

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.

Brownian motion is the random motion of (colloidal) particles due to collisions with the atoms and molecules of the solvents, which are moving due to temperature.

This thesis presents insights from our study of various correlated electron systems with a scanning tunneling microscope (STM). In ordinary metals, electron-electron interactions exist, but get substantially screened due to the sheer number of electrons.

Mechanical forces are known to play an important role in bacterial colonies. In this dissertation, we study the self-organization at various stages of growing bacterial colonies, and focus on the mechanical effects of cell growth.

We explored how to morphologically classify well-resolved jetted radio-loud active galactic nuclei (RLAGN) in the LOw Frequency Array (LOFAR) Two-metre Sky Survey (LoTSS) using machine learning.

Programs that aim to reduce symptoms of social anxiety in children generally include multiple components, such as exposure and cognitive restructuring. It is unknown if separate components yield positive intervention effects in children or whether a combination of components is required.

The Horizon 2020 project CoSTREAM aims to improve our understanding of the co-occurrence of stroke and Alzheimer’s disease. It has long been known that both diseases share underlying causes, but their exact interaction or link is not fully understood. CoSTREAM combines multiple factors to identify and…

In this thesis, deep learning is studied from a statistical perspective. Convergence rates for the worst case risk bounds of neural network estimators are obtained in the classification, density estimation and linear regression model.

One and half years ago, Lewis Borck exchanged the arid and hot Southwest of the USA for the Netherlands. While an expert in Ancestral Pueblo and Hohokam archaeology, he switched to the Caribbean as a researcher in the NEXUS 1492 project. “Theories and methods brought me in first.”

A semi-empirical version of the specific reaction parameter approach to density functional theory (SRP-DFT) has been remarkably successful at predicting dissociative chemisorption probability vs. incidence energy curves for reactions on metal surfaces. New quantum Monte Carlo (QMC) calculations on the…

Taal als sleutel tot het begrijpen van de mens.

Nobody is better qualified to tell you what it is like to work at Leiden University than the employees themselves. Watch the videos and meet your future colleagues. They will be happy to share their experiences with you.

A selection of recent publications from the Plant BioDynamics Laboratory.

This project is situated within the context of an innovation of the biology curriculum in Dutch secondary schools. The main purposes are (1) to clarify the relation between teachers’ practical knowledge and the decisions they make when planning and implementing their lessons and (2) to develop a professional…

Symposium

This subproject of 'From Homo Economicus to Political Animal' analyzes Greek economic thinking in late 5th- and 4th-century philosophical circles.

In the spirit of 'unity in diversity', our objective is to promote insight into and appreciation for the wonder that the same physical laws and mathematical concepts apply to the whole of nature, from the largest to the smallest energy and length scales. We strive for the application of abstract theoretical…
