In this Ph.D. thesis, we characterized two novel upstream regulators of JUB1, HB40, and HB22, in Arabidopsis thaliana. In Chapter 2, we described functions of HB40 in modulating growth and development via the regulation of JUB1 and GA inactivation genes GA2OXs.

The group structure of Jihadist networks changes rapidly, which makes it difficult to monitor them. This is the finding of research by criminologist Jasper de Bie. PhD defence 14 April.

To address the relevance of Christianity to the ideological negotiations with the officially established authority, this research will be conducted by asking how the history enthusiasts negotiate the Christianity-related ideology through reconstructing the Christian past and reproducing religious histories…

The modern-day Caribbean is a stunningly diverse but also intricately interconnected geo-cultural region, resulting partly from the islands’ shared colonial histories and an increasingly globalizing economy.

The most commonly used method for the taxonomic identification of tree trunks is wood anatomy. The number of experts in this area is decreasing, and education to become an wood anatomists takes many years. With the help of technology computer scientists of the Leiden Institute of Advanced Computer Science…

‘It has never been so easy to set up a Studium Generale series.’ With these words Tilman Grünewald thanked speaker Frank den Hollander, who kicked off the Studium Generale series on complex networks on Monday 20 February.

In 2018 NETWORKS organised a very succesful masterclass on networks and their applications for secondary school students with the title 'NETWORKS goes to school'. This week, NETWORKS published the collection of contributions with an extensive introduction. The aim of both the masterclass and this…
