In this dissertation, we study partition-based models that can be used both for interpretable predictive modeling and for understanding data via interpretable patterns.

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 divided into two parts. In Part I we study metastability properties of queue-based random-access protocols for wireless networks. The network is modeledas a bipartite graph whose edges represent interference constraints. In Part II we study spectra of inhomogeneous Erdős-Rényi random…

In dit proefschrift wordt gekeken naar de produktie en consumptie van het reality-tv-programma ‘Nieuwe Wijze Oom’. Deze show, uitgezonden op het entertainmentkanaal van de provincie Shanghai, draait om mediation in conflicten tussen burgers. ‘Nieuwe Wijze Oom’ is geliefd bij het publiek én bij de autoriteiten.…

How does the management of Elephant Marsh Fishery in Malawi relate to wider contexts of policies, theories and regions? And how can the current management system be adapted to achieve long-term sustainability of the fishery?

A complex community of microbes develops in the infant gut shortly after birth. We call this community the infant gut microbiota. The microbiota influences the health of the infant, which makes the composition and function of the infant gut microbiota an important topic to study.

Lipid signaling is an essential biological event/process in a plethora of pathophysiological conditions. The underlying idea of this thesis is that many of the roles and the complex interplay of the individual signaling lipids in inflammatory processes and related conditions in health and disease is…

Mechanical metamaterials are carefully engineered materials whose properties are controlled by their structure, not by their composition, which allows using metamaterials to study and control physical effects in detail⁠.

What invertebrates are available to feed nestlings in an agricultural landscape of varied complexity?

In this thesis we study products of linear error correcting codes.

Vitamin A or retinol is essential in embryonic development, the visual cycle and the immune system.

This dissertation is a collection of four research articles devoted to the study of Kummer theory for commutative algebraic groups.

The thesis is about the study of shell evolution of the Hydrocenidae of the genus Georissa. This thesis started with a general overview on the evolutionary process of animals due to ecological changes.

Arithmetic geometry concerns the number-theoretic properties of geometric objects defined by polynomials. Mathematicians are interested in the rational solutions to these geometric objects.

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

The largest genus within the Phyllanthaceae family is a group called Phyllanthus L. Recent studies have shown, that Phyllanthus is paraphyletic with the genera Glochidion, Breynia and Synostemon nested within it.

Big celebration upcoming weekend: MIRD's 20th anniversary is on the cards. Four alumni from different periods tell what this unique two-year master's in International Relations and Diplomacy has brought them.

What is movements and corridors of the Bornean pygmy elephant in Sebuku forest? What is the nature of human-elephant conflict in Nunukan District in time and space? What are the diets of the Bornean elephants related to crop raiding?

Comparing the global warming potential (GWP) of the service provided by an iRex Digital Reader to the same service provided by an office printer using a scanning LCA.

This thesis focuses on the study of transient and variable radio sources in the universe.

In this thesis we use Josephson and noise scanning tunneling microscopy for the study of conventional, unconventional (iron-based) and disordered superconductors. On the one hand, Josephson scanning tunneling microscopy allows us to directly visualize the superfluid density with high spatial resolut…

This thesis has described novel synthetic methods to produce a variety of (glyco)peptides and their application in the study of various immunological processes.

This thesis contributes to studying primordial cosmology theories and their detectability in future observations.

In this thesis we study quantum transport phenomena on the nanometer scale, in two classes of materials: topological insulators with induced superconductivity and graphene superlattices.

The aim of this thesis is to explore the use of Bioorthogonal Antigens to study the cross-presentation pathway.
