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.

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…

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.

A modern ship design process is subject to a wide variety of constraints such as safety constraints, regulations, and physical constraints.

Empirical Legal Studies in Leiden focust op het bouwen van een interdisciplinaire gemeenschap van rechtsgeleerden en sociale wetenschappers die samen juridische vraagstukken onderzoeken op het snijpunt van recht en gedrag, waarbij diverse soorten methoden worden gebruikt.

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…
