How does the cluster bootstrap procedure in combination with various types of linear models perform in the analysis of longitudinal data, compared to other methods.

In this thesis, we show that we can use Shimura’s CM theory to explicitly compute the Hilbert class field of any primitive quartic CM field.

Latent variable modeling of students' solution strategies and performance

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

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…

This thesis proposes multiple paths towards the development of a performance practice in Computer Music.

Andrea Giolai defended his thesis on 3 May 2017.

The main objective of this thesis was to develop clinically relevant survival models for patients with high-grade soft tissue sarcoma of the extremities, in particular the development and validation of prediction models for use in clinical practice.

Three at the same time: a ligation strategy combining tetrazine–norbornene cycloaddition, Staudinger–Bertozzi ligation, and copper(I)-catalyzed click reaction was used to label the three catalytic activities of the proteasome simultaneously in a single experiment. The orthogonality of the three ligation…

The overall aim of the project is to investigate interests and their development over time in a daily life context, with particular attention for the transition from late secondary to post secondary education, and from late post secondary education to early career.

We will study how inoculation of former arable land with soil (including the microbiome, soil fauna and seeds/rhizomes of ground flora) from old forests along with planting targeted tree species mixtures will improve productivity and more rapidly restore forest-adapted communities and ulttimately result…

Social science research helps us understand human behaviour and social structures. These are determined by various factors, which makes the research complex and increases the likelihood of drawing the wrong conclusions. The choice of research method and analysis is therefore extremely important. It…

Which factors (human-dimension and carnivore related) shape human tolerance of large carnivore and large carnivore survival in multiple use forests?

How has interreligious encounter in Ogbómòsó created multiple religious belongings and identities among individuals and groups?

This thesis has three main parts. The first part gives an algorithm to compute Hilbert modular polynomials for ordinary abelian varieties with maximal real multiplication. Hilbert modular polynomials of a given level b give a way of finding all of the abelian varieties that are b-isogeneous to any given…

Leiden chemists discovered a new mechanism which might explain how multiple sclerosis shifts to a more severe form. Their findings contribute to unravelling the mysterious course of the disease. They have published their findings in the journal Biochemistry.

Computer scientists from Leiden University and the University of Münster describe a new theoretical starting point for approaching difficult optimization problems. They can take into account several criteria simultaneously, instead of just one at a time.

The Netherlands Organisation of Scientific Research has honored the application of Prof. Harry Fokkens for the research project entitled

On 18 June 2019, Peter Kempees defended his thesis 'Hard power and the European Convention on Human Rights'. The doctoral research was supervised by Prof. R.A. Lawson and Prof. H. Duffy.

Disk formation around stars is an important factor in determining whether one or multiple stars evolve. But the big picture of star formation is still far from complete, says PhD researcher Nadia Murillo.

During this semester, the University of Vienna offers the 19th lecture series on Gender Studies. On 21 November 2017, Christa Tobler, Professor of European Law at the Universities of Basel (Switzerland) and Leiden, gave a lecture on the subject of multiple discrimination, including also sex.

To an algebraic curve C over the complex numbers one can associate a non-negative integer g, the genus, as a measure of its complexity.

Cognitive decline (amongst other problems with attention, concentration, memory) is a common symptom in patients with a variety of brain disorders and has been related to healthy ageing as well. People suffering from cognitive deficits are often significantly hampered in their day-to-day functioning…
