In this PhD-thesis several new and existing data science application are described that are particularly focused on applications for tax administrations.

Humans perceive the real world through their sensory organs: vision, taste, hearing, smell, and touch. In terms of information, we consider these different modesalso referred to as different channels of information or modals.

Ice, the solid state of water, plays an important role on our planet as well as the entire universe.Despite the fact that an individual water molecule has a very simple structure, its chemical bonding in the solid phase can be surprisingly complex.

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

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…

Het doel van het RAISE Onderzoek is om te onderzoeken hoe veerkrachtige mensen omgaan met stress. We kijken specifiek naar hoe belangrijke biologische systemen, zoals de HPA-as en het immuunsysteem, samenwerken met de hersenen en de sociale omgeving om veerkrachtig functioneren na moeilijkheden in de…

Sound is everywhere in the marine environment and hearing is therefore a very important for stimuli for fish. They use sound for orientation and communication, during migration, aggregation and spawning, but also for detection of prey and predators.

Geometric phases lead to a nontrivial interference result when an electron's different quantum mechanical paths choices encircle a magnetic coil in an Aharonov-Bohm experiment.

This work describes the use of click-to-release chemistry to get spatiotemporal control over immunocytokine activity. Until now, immunocytokines (cytokines coupled to a tumor-targeting-moiety) remained active throughout the body, being able to bind their respective receptors, causing mild to severe…

Despite the history of studies on methanol formation from CO2, the dominant elementary reaction steps that constitute the chemical mechanism for this catalyzed process are not determined.

The parabolic Anderson model (PAM), which is the Cauchy problem for the heat equation with random potential. The PAM is a mathematical model that describes how mass (i.e. matter or energy) flows in a medium in the presence of a field of sources and sinks.

Building a Deep Cross-media Transfer Network to extract visual relations that relieve the problem of insufficient training data for visual tasks.

In some condensed matter systems, such as the surface of a 3D topological insulator, the electrons are effectively massless and we must necessarily use the massless Dirac equation to describe them.

Een nieuwe manier om het licht van verre planeten te analyseren zou ons bewijs kunnen leveren van buitenaardse planten, schrijft astronomie-auteur Colin Stuart in de New Scientist. In zijn artikel beschrijft hij het werk van de groep van de Leidse astronoom Rob van Holstein. Dit team detecteerde afgelopen…

Planeten in andere zonnestelsels bevatten waardevolle informatie over het ontstaan van planeten en leven. Promovenda Yapeng Zhang heeft hun atmosferen bestudeerd door te kijken naar hun kleinste onderdelen: isotopen. Met haar onderzoek hoopt ze te ontdekken wat ons eigen zonnestelsel uniek maakt.

Tijdens het bestuderen van zestien jaar aan meetgegevens van jonge sterren ontdekte de Leidse masterstudent Sam de Regt dat twee van die sterren nog gehuld waren in geboortewolken. Nog niet eerder bracht iemand deze twee sterren zo scherp in beeld. Hij publiceert zijn opschoonmethode en de nieuwe afbeeldingen…

The function of TLRs in innate immunity has aroused worldwide attention soon after its discovery. Because of the broad functions of TLR2 in innate immunity, the drive for the development of TLR2-targeted vaccines or therapeutic treatments has accelerated in the last decades.

The key purpose of this project is to study tautological relations on the level of closed differential forms or even integral cochains (i.e. we don't take classes in cohomology).

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.

This dissertation presents the results of the importance of creativity for ICT-students of Dutch universities of applied sciences (in Dutch: hogescholen), and the functioning of training courses that aim to promote creative abilities is highlighted.

We have studied shape with a particular focus on the zebrafish model system. The shape is an essential appearance of the phenotype of a biological specimen and it can be used to read out a current state or response or to study gene expression.

In the Schouwburgstraat, LUGO is currently redesigning the back-garden in order to increase biodiversity and make it a more beautiful space. Throughout October 2023 until March 2024, we will be making changes to the garden with our team of volunteers.

Early time-resolved experiments by Frauenfelder on the ensemble of the kinetic rebinding of CO to myoglobin molecules resulted in a stretched exponential relaxa-tion due to a very large spread of the reaction rates of individual molecules.

Whilst government’s ability to design ‘context-specific’ regional innovation policy is generally assumed to depend on the region’s decision-making power, the aim of this study is to investigate how regional government matters. In order to open up the black box of policy design, the study develops a…

OB associations are loose groups of young, massive stars. They constitute the last stage of the massive starformation process, and the context in which new stars are formed.

The intradermal administration route is attractive for vaccine delivery, because of the highly populated antigen-presenting cells in the skin. However, the skin’s main physical barrier, the stratum corneum, prevents vaccines from entering the skin.

The research presented in this thesis makes use of small molecules (as H2 , D2 and O2 ) on well-defined single crystal surfaces (flat Pt(111), flat Cu(211) and curved Pt(111)) to elucidate the role of surface structure and degrees of freedom in the reactant in specific surface reactions.

A management strategy has been developed for field margins to reduce pesticide drift to non-target areas and to promote biodiversity on arable land. To this end, 3 and 6 m wide strips along the edges of winter wheat, sugar beet and potato crops have been left unsprayed with herbicides and insecticides…
