In my research, we developed a method to distinguish knots. A knot is a mathematical depiction of the everyday knot that occurs in ropes and cords.

This thesis focuses on protoplanetary disks: flattened structures of gas and dust around young stars in which planets are expected to form and grow.

Als we een tekst lezen denken we te weten wie hem geschreven heeft, maar in de vroegmoderne periode was de productie van manuscripten vaak een gezamenlijke of 'gesocialiseerde' onderneming met secretarissen en schrijvers die fysiek schreven wat de auteur dicteerde.

The research presented in this thesis concerns one of the most important questions in software engineering of our time: how can we make sure that software is free from memory safety bugs?

This thesis describes the functional analysis of the Arabidopsis AHL15 gene.

Metal complexes and 2D materials like graphene were combined to produce structures that can function as sensors.

Natural resources often stretch across borders that separate modern nation states. This can create conflict and limit opportunities for regulated consumption of their goods and services, but also provide opportunities for joint multinational efforts that exceed single country capabilities.

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.…

BlaC is the β-lactamase of Mycobacterium tuberculosis. We show that it can recover from inhibition by clavulanic acid and that phosphate helps it do so.

Muziekinstrumenten zijn meerdere dingen: het zijn objecten, maar ook communicatiemiddelen; ze zijn technologisch en ook diep verbonden met belichaming via de speler; en ze laten bepaalde culturele sporen na (Ricoeur 1975/1984). Dit onderzoeksproject onderzoekt hoe literaire teksten van de 19e eeuw tot…

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…

Over the last decades, aviation safety has improved strongly. As a downside, airline pilots do not have as many opportunities to develop through experience the competencies that they need in critical situations.

Stars like the sun are born in large molecular clouds existing from gas and dust. During the formation process, the chemical composition of the material can be altered drastically by the changing physical conditions.

The complexity of an intelligence problem determines to a great extent the certainty that can be provided by intelligence and security services.

This thesis contains results on the arithmetic and geometry of del Pezzo surfaces of degree 1.In Chapter 1 we give the necessary background, assuming the reader is familiar with algebraic geometry.

Alle ogen waren gericht op China tijdens het congres van de Chinese Communistische Partij. Een goede gelegenheid voor president Xi Jinping om zich wereldwijd te profileren. Op NU.nl legt hoogleraar Frank Pieke uit hoe hij dit deed.

This thesis is is made of three parts. The first part describes a generalization of the Chabauty's method, that can be used to determine the rational points of a curve such that s+g>r+1, where g is the genusof the curve, r is the rank of the Mordell-Weil group of the jacobian of the curve and s is…

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

In this thesis, we have used numerical approaches to study the effects of translational symmetry breaking on strange metallic systems as realised by the holographic duality⁠.

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

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”.

In astronomy, the interpration of observations and measurements plays a crucial role: we rely purely and fundamentally on the information that reaches us as observers. And 80% of all matter in the universe is undetectable directly.

The ability to count is a property not often attributed to materials, despite the abundance of memory in materials. Regardless of how a material stores information, it is often difficult to retrieve exactly ‘what’ a material remembers.

Galaxies are environments where gas coalesces, cools, and is converted into stars. However, it remains unclear the exact mechanisms through which galaxies acquire, redistribute and lose their gas.

This thesis discusses the physical and chemical processes than influence the composition of forming planets.

The increasing resistance of pathogenic bacteria to antibiotics necessitates the discovery of new medicines.

Biological cells, the basic building blocks of all life forms, are surrounded by a lipid membrane. More than half of the membrane is occupied by membrane proteins, which can regulate the cell functionality through specific arrangements.

Multiple stars, that is two or more stars composing a gravitationally bound system, are common in the universe.

β-Lactamases are enzymes that can break down β-lactam substrates, such as antibiotics, preventing the use of these antibiotics for the treatment of various infectious diseases. However, some compounds, β-lactamase inhibitors, can block these enzymes allowing for possible treatments using a combination…

Plants, are sessile organisms, have developed strategies to adapt to changes in their environment, in part by altering their growth and development.
