This thesis focuses on important life history traits and their trade-offs using two hexapod models. Particularly, the trade-off between immune defense and embryonic developmental speed is a central theme of this study.

The applications of studying the early development of insects range from agriculture to material science.

Complex Organic Molecules (COMs) have been detected in objects across different stages of stellar evolution.

This thesis is comprised of three chapters covering the theme of studying semistable varieties by looking at their dual combinatorial objects.

In this thesis we explore machine and deep learning approaches that address keychallenges in high dimensional problem areas and also in improving accuracy in wellknown problems. In high dimensional contexts, we have focused on computational fluid dynamics (CFD) simulations.

This dissertation consists of two parts, each of which considers a different research area related to random interval maps. In the first part we are interested in random interval maps that are critically intermittent.

The European Council and the European Commission have a similar role in agenda setting. Both place issues on the EU agenda. However, these institutions have distinct designs. They have different political attributes (the European Council has considerably more political authority) and information-processing…

Materials with strongly correlated electrons show some of the most mysterious and exotic phases of quantum matter, such as unconventional superconductivity, quantum criticality and strange metal phase.

The research presented in this thesis explores the chemotherapeutic potential of metal-based compounds as chemotherapy agents, with an initial focus on the synthesis and DNA interaction studies of platinum and palladium compounds utilizing the [Pt(bapbpy)]2+ scaffold. The study identifies intercalation…

What physics controls the properties of quantum matter, such as how electrons flow inside high-temperature superconductors? This question has captivated the physics community and industry for decades, in part due to the great technological potential such materials have, but also because they have resisted…

The sequence-dependence of biomolecular interactions involving nucleic acids and proteins is essential for numerous processes inside the cell. Insights into the underlying molecular mechanisms have been obtained using various biochemical and biophysical methods on two different levels — bulk and sin…

In this thesis, I focused on studying the above- and belowground interactions of J. vulgaris from a plant-soil feedback (hereafter, PSF) perspective. I investigated the temporal variation of negative PSF and examined the effects of root-associated bacteria on plant performance and aboveground herbiv…

This thesis studies the geometry of representation varieties and character stacks. These are spaces parametrizing the representations of a finitely generated group, typically the fundamental group of a compact manifold, into an algebraic group G.

Jorrit Rijpma, universitair hoofddocent EU recht aan het Europa Instituut, heeft een Jean Monnet Chair gekregen van de Europese Commissie.

This study’s main aim is to test whether children’s learning behaviour explains why they do not benefit from a literate environment.

Het Research Lab for the Study of Heritage Languages of the Netherlands (HERLING) is een platform voor onderzoek naar erfgoedtalen die in Nederland worden gesproken, met een focus op Turks, Bahasa Indonesia, Spaans, Papiamento, Berbers, Arabisch en Duits. HERLING wil een brug slaan tussen wetenschappelijk…

The objective of this study is to better understand the distribution of microplastics in the environment. More specifically, we will quantify the abundance and distribution of microplastics on beaches.

Op donderdag 15 december is Elisavet Alexiadou gepromoveerd op haar proefschrift: ‘The Right to Health. A Human Rights Perspective with a Case Study on Greece'. Promotor was hoogleraar gezondheidsrecht Aart Hendriks.

This study tests whether behavioural problems at a young age are related to early reading and mathematics development.

What holds people together and what makes them willing to fit within larger political structures? Our project examines this question in the practices of dynastic rulership in Eurasia ca. 1300-1800.

In this thesis, the discovery and optimization is described of chemical tools to study the N-acylethanolamine (NAE) biosynthetic pathway.

In recent decades, climate change has led to more frequent and severe drought events, causing serious consequences such as increased forest mortality and significant crop yield losses. Understanding how drought affects plants, especially economically important herbaceous species, is crucial for predicting…
