Heterogeneous catalysis is one of the fundamental processes of modern life, being common in industrial refinery and hydrogen vehicles, all the way to the living cell. The dissociation of H2 on Cu(111) is an important benchmark system for studying heterogeneous catalysis, with a large and varied amount…

In the first part of this thesis we study the geometry of folding patterns.

Human language is constantly evolving with its linguistic structure being shaped by language users at both individual and population levels. Focusing on the interplay between processes of language acquisition and communicative need in shaping human languages, this thesis introduces a novel computational…

This dissertation advances automated negotiation by developing agents that can learn and adapt across diverse negotiation settings through three increasingly sophisticated approaches: automated algorithm configuration, portfolio-based strategy selection, and end-to-end reinforcement learning with graph…

In this thesis we study the moduli space of genus g curves, and the differential forms that occur naturally on this moduli space.

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.

The thesis introduces three methods for high-dimensional prediction problems in the biomedical field. The methods make use of empirical and variational Bayes in the estimation.

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

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.

This thesis is dedicated to the exploration of the primordial dark ages: unknown physics during the earliest stages of the Universe’s expansion that have not yet been directly probed by observations. Cosmic inflation is a burst of exponential expansion of space after the “Big Bang”.

Urbanisation is steadily increasing with estimates expecting that 68% of the global population will live in cities by 2050. To accommodate the rural to urban transition, large quantities of land are transformed from natural to urban lands.

We show that Kirchhoff ’s law of conservation holds for non-commutative graph flows if and only if the graph is planar. We generalize the theory of (Euclidean) lattices to infinite dimension and consider the ring of algebraic integers as such a lattice.

Make more fluid: In condensed matter systems, electrons can acquire unusual properties from their interaction with the atomic lattice.

Evolution acts via mutations in amino acid sequences. Substitution of essential amino acids leads to a nonfunctional protein. l.

This Thesis shows discoveries in non-linear astrochemical kinetics as well as a deeper analysis of dark clouds chemistry.

We have examined sequences from the ligand-binding domain of the nicotinic acetyl choline receptor (nAChR) in 148 vertebrate species. We are in interested in this receptor because the α-neurotoxins of many venomous snakes binds to this receptor in its location at the neuromuscular junction in all ve…

The research in this dissertation aims to optimise blood donation processes in the framework of the Dutch national blood bank Sanquin. The primary health risk for blood donors is iron deficiency, which is evaluated based on donors' hemoglobin and ferritin levels.

In deep reinforcement learning, searching and learning techniques are two important components. They can be used independently and in combination to deal with different problems in AI, and have achieved impressive results in game playing and robotics. These results have inspired research into artificial…

Chinese materia medica (CMM), comprising a diverse array of natural substances from plants, animals, and minerals, has been integral to Traditional Chinese Medicine (TCM) throughout history. This study investigates the dynamic evolution of CMM, noting shifts in species for improved therapeutic effects…

There is an increasing amount of attention on EU and its Member States contributions to implementation of two landmark agreements: the Paris Climate Agreement and the UN Agenda 2030 with Sustainable Development Goals (SDGs). Absent from the current literature is an analysis of the political effect of…

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

My PhD research is devoted to studies of the conjectural cluster-algebraic symmetry in the theory of topological string, which is the simplest, however already non-trivial sector in the theory of string.

This thesis studies operator-algebraic aspects of subproduct systems, a generalization of product systems of Hilbert spaces.

We use DNA strands to stabilize few-atom silver clusters, which show unique optical and chemical properties. This thesis involves the study of these constructs for various applications.

This thesis concerns the relation bettween the good reduction of Shimura varieties and the associated loop groups.

In this thesis, two potential therapeutic targets for diabetic nephropathy were dentified and investigated. First, we show that glomerular clusterin is upregulated in diabetic nephropathy and demonstrated that recombinant clusterin protein can protect the podocytes against oxidative stress in vitro.…

We prove a p-adic version of the work by Gross and Zagier on the differences between singular moduli by proving a set of conjectures by Giampietro and Darmon, who investigated the factorisation of a rational invariant associated to a pair of CM-points on a genus zero Shimura curve, obtained as the ratio…

In this thesis new methodologies are developed for the detection and systematic study of radio sources in the early universe. This allows us to gain a deeper understanding of the formation and evolution of galaxies, the activity of supermassive black holes, and the final phase transition of our universe:…

Gold nanoparticles show surprisingly strong interactions with light in the visible range, which can be divided into scattering, absorption, and photoluminescence.

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…

Almost all bacteria are enveloped by a cell wall that provides cellular protection.

In this Thesis, novel charge induction mechanisms of ionic liquids are treated, tested and experimented on complex oxides, in particular cuprates.
