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.

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

Carbohydrates, or sugars, are the most diverse and most abundant biomolecules known. However, the isolation of carbohydrate samples in sufficient amounts and purity is often impractical or even impossible, so the chemical synthesis of glycosides becomes relevant. The glycosylation reaction, in which…

Gibbs measures, as used in Statistical Mechanics, have a definition that is remarkably similar to the definition ofg-measures, used in dynamical systems.

In this thesis, rational points on K3 surfaces are studied. In the first part of Chapter 1 the Brauer group and the the Brauer-Manin obstruction are introduced.

Explore "Surgical anatomy of the leg in relation to nerve injuries" at Boerhaave Nascholing. Read more here.

In this course, you will explore the organs involved in our food digestion and discover the common causes of abdominal and pelvic pain. The latest graphics and animations will give you new insights and understandings of this part of the body.

Kidney transplantation is a major advance of modern medicine. This course will give you state of the art updates about what used to be an experimental, risky, and very limited treatment option more than 50 years ago and is now routinely performed in many countries worldwide.

This course uses the lives, ideals and achievements of Theodore, Franklin, and Eleanor Roosevelt to create the idea of a Rooseveltian century. It is an invitation to think critically and historically, and it wants to give you a glimpse of what it means to be a historian at work.

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.

Statistical distributions in LCA and converting between different representations of these distributions.

In this thesis we examine certain phenomena in symplectic topology which are related to the theory of isolated singularities.

This thesis combines field and laboratory studies to address some of the most pressing questions in the field of microplastic research.

This thesis mainly focuses on cross-modal retrieval and single-modal image retrieval via deep learning methods, i.e. by using deep convolutional neural networks.

In this thesis chemical and physical processes in the ice mantles on interstellar dust grains are studied.

This thesis mainly focuses on multimodal understanding and Visual Question Answering (VQA) via deep learning methods. For technical contributions, this thesis first focuses on improving multimodal fusion schemes via multi-stage vision-language interactions.

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…

Op 23 juni 2020 verdedigde Santy Kouwagam haar proefschrift 'How lawyers win land conflicts for corporations: Legal Strategy and its influence on the Rule of Law in Indonesia'. Het promotieonderzoek is begeleid door promotoren prof.dr. A.W. Bedner en prof.dr. C.E. von Benda-Beckmann.

This dissertation is part of a broader research project that revolves around unraveling the evolution of balanced lethal systems.

Leiden University offers a unique range of summer courses where you can broaden or deepen your knowledge or share your expertise with fellow students. The choice of academic courses is very diverse, ranging from Law, Big Data, Languages and Linguistics to Maths and Natural Sciences, Biology, Biomedical…

This PhD thesis concerns the topic of arithmetic geometry. We address three different questions and each of the questions in some way is about counting how big some set is or can be.

This thesis describes the design and development of subunit‐selective inhibitors of particular catalytically active subunits of human constitutive proteasomes and immunoproteasomes.

Bacterial chemosensory arrays are protein assemblies that are the key structural and functional component for motile bacteria to sense their internal or environmental chemical signals.

In dit project worden reisverslagen over Nederlands-Indië bestudeerd die zijn geschreven tussen 1800 en het einde van de Tweede Wereldoorlog. Door zowel Nederlandse reisteksten als inheemse reisteksten in het Javaans en Maleis te analyseren, wordt een nieuw, tweestemmig perspectief op (de geschiedschrijving…

In times of hardships or crisis, local people know how to deal with it using their resourcefulness. Although efforts are sometimes made by the government to help them, they are fully aware that community support is at least equally important.

SDN (Software-Defined Networking) represents a revolutionary approach to network architecture that enables the dynamic and flexible management of network resources through software-based control. This dissertation introduces the idea of SDN and its southbound protocol OpenFlow, then presents the formal…

Tracing the evolution of the molecular gas content in galaxies is critical for a complete understanding of galaxy formation and evolution, as it provides the direct fuel for star formation. Studies of high-redshift (z>1) molecular gas reservoirs, most commonly traced by carbon monoxide (CO), have seen…

This thesis describes a study from both a theoreticaL and an experimental point of view.

In the first part, we introduce a new condition, called toric-additivity, on a family of abelian varieties degenerating to a semi-abelian scheme over a normal crossing divisor.

We explored the Universe using weak gravitational lensing, a phenomenon that occurs when light from distant galaxies is bent by the gravitational fields of closer cosmic objects, much like how a lens distorts light.
