Surface acoustic waves (SAWs) are mechanical waves that travel along the surface of a material and find many applications in modern technologies due to the ease of excitation on piezoelectric substrates via interdigital transducers (IDTs).

Hoe heeft migratie de Ierse en Italiaanse samenleving sinds 1945 beïnvloed?

Professor Dirk Vandewalle is een internationaal veelgevraagde en gerenommeerde Libië-expert. In deze lezing gaat hij in op twee essentiële vragen over de huidige situatie in Libië. Hoe komt het dat het Libische politieke systeem zo fragiel geworden is? En hoeveel hoop is er nog dat Libië als eenheid…

Hoe kiezen dieren hun partner? Het antwoord is simpel: alles draait om kwaliteit. Willen wij mensen nog wel eens iets aantrekken wat toevallig in de mode is, dieren doen niets zomaar. Achter een mooi verenkleed of een oor¬verdovend brullen zit maar één boodschap: ik ben in topconditie. De evolutionaire…

Viral hemorrhagic fever (VHF) is a group of acute diseases caused by highly infectious viruses including Ebola, Lassa, Dengue viruses. Its high mortality rate poses high risk to public health, however, studies on VHF have been hampered due to the non-availability of proper models and incomplete knowledge…

Anthropogenic noise has been shown to affect marine animals in various ways, this may have fitness consequences at individual and population level. This thesis aims to increase insight into the quantification of sound-induced behavioural responses that are relevant to fitness, and into factors that…

We study the interplay of topology and geometry with chirality for several passive and active systems, employing both analytical and numerical methods.

Lezing, This Time for Africa!

This thesis investigates the structural evolution and assembly of galaxies since the first few billions years after the big bang.

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…

Visualizing the internal structure is a crucial step in acquiring knowledge about the origin, state, and composition of cultural heritage artifacts. Among the most powerful techniques for exposing the interior of cultural heritage objects is computed tomography (CT), a technique that computationally…

Transplantation of labial salivary glands to the eyelids for patients with dry eye appears to give excellent results clinically.

In meta-analysis, heterogeneity often exists between studies. In such cases, it is essential to investigate the sources of heterogeneity and understand the relationship between effect size and study characteristics (i.e., moderators).

In this thesis, deep learning is studied from a statistical perspective. Convergence rates for the worst case risk bounds of neural network estimators are obtained in the classification, density estimation and linear regression model.

A remarkable population of short period transiting rocky exoplanets with equilibrium temperatures on the order of 2,000 K has recently been discovered.

We consider the propagation of electrical signals through nerve fibres.

Low-carbon (LE) technologies have a significant potential to reduce the total carbon emissions in China.

We investigate the buildup of galaxies from various vantage points. The first two chapters focus on the stellar content of galaxies, especially the distribution of stellar masses at birth and potential variations therein in various galactic environments.

Plants and their pollinators form complex interaction networks. Within these networks, species differ widely in the number of species they interact with.

When observing star-forming galaxies, we are not only seeing stellar light, but we also see how this interacts with galactic gas and dust. This thesis contains studies of the stellar, nebular and dust properties of low mass star-forming galaxies.

This thesis seeks to combine two different research topics; Multi-Objective Optimization and Complex Network Analysis.

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.

The investigation into the bidirectional communication between the gut and its host is a rapidly growing area of research, attracting considerable attention for its potential to provide crucial insights into health and disease.

The studies presented in the work show the potential of the integrative use of biophysical data in defining the structural basis of protein interactions.

We strive to address the challenge of constructing a modeling language to write software which can take advantage of recent hardware developments (multicore, cloud) without compromising in its abstraction levels.

Enzymes are innately sensitive to changes in the amino acid sequence, which largely constrains their evolutionary potential, i.e., evolvability. This evolutionary burden can be alleviated in the presence of stabilizing mutations, which increase the buffering capacity of enzymes to tolerate mutations…
