The main theme of this thesis is the theoretical study of Gaussian processes as a tool in Bayesian nonparametric statistics.

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.

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…

In this thesis, we explore a Hochschild homology and cohomology-like notion for logarithmic schemes.

Quantum computing is an emerging technology, which holds the potential to simulate complex quantum systems beyond the reach of classical numerical methods.Despite recent formidable advancements in quantum hardware, constructing a quantum computer capable of performing useful calculations remains challenging.In…

The main object of study in this thesis is an Arakelov inequalitywhich bounds the degree of an invertible subsheaf of the direct image ofthe pluricanonical relative sheaf of a semistable family of curves.

The largest structures in the Universe are clusters of galaxies. Each can contain hundreds to thousands of galaxies.

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

The Sun and all the stars in the night sky reside in the Milky Way galaxy. In the at-rest reference frame of the Galaxy, typical stars travel with velocities of about 100-200 kilometres per second.

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.

This thesis is about cosmological inflation and its relation to observations.

This thesis provides explicit expressions for the density functions of absolutely continuous invariant measures for general families of interval maps, that include random maps and infinite measure transformations, not necessarily number systems.

Given the accelerating appearance of antimicrobial resistance, there is an urgent need for more fundamental research into novel antibiotic strategies. The work in this thesis helps to address this global problem by developing new antibiotic compounds, inspired by the antibacterial mechanisms of the…

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

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 thesis describes the design, synthesis, and immunological evaluation of varying (neo)antigenic peptide conjugates containing either a TLR2 or a TLR7 agonist.

Bij de Onderzoeksgroep Geweld en Geweldpreventie (Violence and Violence Prevention) wordt onderzoek gedaan naar de complexiteit van hedendaags geweld, de uiteenlopende verschijningsvormen ervan en strategieën voor preventie.

The theoretical explanation of cosmic acceleration is nowadays one of the biggest puzzles in cosmology.

In this work, we attempt to answer the question:

Quantum hardware comes with a different computing paradigm and new ways to tackle applications. Much effort has to be put into understanding how to leverage this technology to give real-world advantages in areas of interest for industries such as combinatorial optimization or machine learning.

Time-series forecasting through modelling sequences of temporally dependent observations has many industrial and scientific applications. While machine learning models have been widely used to create time-series forecasting models, creating efficient and performant time-series forecasting models is…

The Standard Model (SM) of particle physics fails to explain several observed phenomena and is incomplete. In order to resolve this problem, one may extend the SM by adding new particles.

Sustainable energy from wind and solar is most readily available near the sea.

Real-life processes are characterized by dynamics involving time. Examples are walking, sleeping, disease progress in medical treatment, and events in a workflow.

This thesis involves three topics: benchmarking discrete optimization algorithms, empirical analyses of evolutionary computation, and automatic algorithm configuration.
