This thesis describes the use of the evolutionary approach in the study of language change, aiming to provide a better insight in the mechanisms that play a role in language change and to validate this approach in the field of language change.

BACKGROUND: Explant human skin equivalents (Ex-HSEs) can be generated by placing a 4mm skin biopsy onto a dermal equivalent. The keratinocytes migrate from the biopsy onto the dermal equivalent, differentiate and form the epidermis of 1(st) generation Ex-HSEs. This is especially suitable for the expansion…

This article describes that although the use of the concept of energy justice is new, normative interpretations have long been part of energy policy.

Refugees’ effect on domestic terrorism is conditioned by host-country social perception (attitude about living next-door to foreigners) and economic competition. These hypotheses are tested cross-nationally from 1995-2014 leveraging data from the World Values Survey.

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

Sprayable plant-based adhesives for crop protection against thrips Some plants, such as sundew and tomato, protect themselves with sticky hairs that repel or even trap arthropod herbivores.

Quantum computing represents a fundamentally new computational paradigm, capable of addressing problems that are intractable for classical computers.

Mei-Wen Chen defended her thesis on 29 June 2016

Late Antiquity is characterized by migration movements, political unrest and religious strife. The way we assess these religious conflicts is often coloured by a post-Reformation understanding of ‘religion’. In my research, I show that late ancient authors understood religion in a way that differs much…

Now online in Molecular Microbiology our studies on the motility of Sulfolobus acidocaldarius and its unique swimming organelle, the archaellum.

Optical cavities are useful tools to enhance the interaction between light and matter, which is important to make good quantum emitters. However, it turns out that the cavities themselves (without any quantum emitters) are already interesting objects to study.

Here I propose to study the relationship between autonomic pupil-synchronisation and trust, at the behavioural and neural level, and examine a targeted set of possible contextual moderators.

This project, executed by Marieke Hendriksen MA MRes, aims at an analysis of how the early modern anatomical collections of Leiden University were rooted in ideals of perfection in different fields of knowledge and expertise.

The discovery of new medicines is a tedious and lengthy process. On average, over 10,000 molecules need to be studied for one to become a drug and reach the patient. Part of that process are the very costly clinical trials in humans, and candidate drugs often fail due to side effects or lack of efficacy.…
