Despite being the object of intense study, embryonic development has been difficult to model due to a number of reasons. First, complex tissues can be comprised of many cell types, of which we probably only know a subset.

In the thesis the dynamics of strategies is studied from two perspectives.In the first part of the thesis strategies are considered to be opinions present in a community.

Diverse types of exoplanets such as gas giants on close-in orbits (hot Jupiters) and young massive giants on wide orbits (super Jupiters), with no analogs in the Solar System, pose challenges but also opportunities to our understanding of planet formation and evolution.

Artin L-functions associated to continuous representations of the absolute Galois group G_K of a global field K capture a lot of information about G_K as well as arithmetic properties of K.

In this dissertation, matching, entropy, holes and expansions come together. The first chapter is an introduction to ergodic theory and dynamical systems.

We have conducted a full spectral line survey of the 3-13 micron region of two massive protostars, AFGL 2591 and AFGL 2136, for the first time at high spectral resolution.

Hieronder vind je de antwoorden op een aantal veelgestelde vragen over toelating tot de klinische specialisaties van de Master Psychologie.

Within this thesis the central stage is taken by the discovery and investigation of transglycosylation of sterols. First, investigation focuses on the development of a method to accurately detect and quantify glucosylated metabolites in biological materials.

In my thesis I study Majorana fermions from three different perspectives. The first one corresponds to non-interacting Majorana fermions that, however, pose non-trivial topological properties. The second one corresponds to strongly interacting Majoranas and the third to relic neutrinos. No one knows…

Congres/symposium

Op 19 januari 1935 werd de Stichting ‘Leids Papyrologisch Instituut’ opgericht. De drie oprichters – J.C. van Oven (1881-1963, hoogleraar Romeins recht), B.A. van Groningen (1894-1987, hoogleraar Grieks) en M. David (1898-1986, hoogleraar Rechtsgeschiedenis) – gaven toen al enkele jaren colleges Griekse…

This pioneering project will answer this question by examining migrants through the eyes of the courts between 1600 and 1900. It aims to reveal patterns of continuity and change in: 1. Treatment of migrants by criminal courts; 2. Violence and conflicts between migrants and native born.

A single self-assembled semiconductor quantum dot in a high-finesse optical microcavity - the subject of this thesis - is an interesting quantum-mechanical system for future quantum applications. For instance, this system allows trapping of an extra electron and thus can serve as a spin quantum memory,…

Description of Biotic ligand models: making an inventory of available models & assessment of the variability of the predicted HC5 using the BLMs in different Dutch water types (2005 - 2007)

This dissertation presents a new perspective on the life, work and character of the Dutch physical chemist Jacobus Henricus van ’t Hoff, first recipient of the Nobel Prize in Chemistry, and one of the most important and colourful scientists in Dutch history. The image of Van ’t Hoff that emerges from…

Announcement of a new publication by Janneke Verheijen, lecturer at the Institute of Cultural Anthropology and Development Sociology.

It researches (the possibilities for) the development of a set of principles and best practices for insolvency office holders by comparing multilateral treaties and soft law recommendations and national legislation within Europe.

D1.2 reports on the findings of an analysis of framework conditions relevant in the context of the data economy from a legal, a socio-economic and a technological perspective. The analysis is a key foundation for the creation of an initial, heuristic model of the European data economy. The deliverable…

In this work we describe three methods to improve the performance of Quantum Field Theory calculations.

This thesis has described novel synthetic methods to produce a variety of (glyco)peptides and their application in the study of various immunological processes.

The first direct detection of gravitational waves opened the possibility of mapping the Universe via this new and independent messenger.

In this thesis, time-lapse fluorescent microscopy plays a pivotal role in investigating functional materials within living cells as well as the migratory behaviour of neural progenitor cells.

This thesis describes how different colours of light affect various aspects of the growth and development of Arabidopsis and tomato plants⁠.

Freshwater biodiversity has been threatened by eutrophication due to excessive nutrients in the environment. Releasing the freshwater species from such pressures requires efforts from industry and manufacturers to avoid emissions to vulnerable and high-risk regions.

In this work the reconstruction of a tau neutrino signal in the KM3NeT detector is discussed.

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.

The main goal of this thesis is to achieve advanced control of binding properties in bis-pyrrolic and macrocyclic pyrrolic receptors by light.

In this thesis we study quantum transport phenomena on the nanometer scale, in two classes of materials: topological insulators with induced superconductivity and graphene superlattices.

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…
