Throughout the history of computer science, a major challenge has been how to assert that software is free of bugs and works as intended. Software bugs can lead to serious negative impacts on any software system. Throughout the main body of the thesis, we implemented a series of studies on exploring…

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.

Stars like the sun are born in large molecular clouds existing from gas and dust. During the formation process, the chemical composition of the material can be altered drastically by the changing physical conditions.

Hydrocarbonylation of alkenes with carboxylic acids in synthesis of carboxylic acid anhydrides is relatively less explored. We herein present a study and optimization of a palladium-catalyzed hydrocarbonylation reaction of alkenes using carboxylic acids as the nucleophile, by which acid anhydrides can…

The marine shipping industry is one of the strongest emitters of nitrogen oxides (NOx), a pollutant detrimental to ecology and human health. Over the last 20 years, the pollution produced by power plants, the industry sector, and cars has been decreasing.

The class-imbalance problem is a challenging classification task and is frequently encountered in real-world applications. Various techniques have been developed to improve the imbalanced classification performance theoretically and practically.

Almost three years after receiving her honorary doctorate, Dr Graça Machel returned to Leiden University. Over the course of two days she spoke with students, researchers, and other interested persons, about human rights – particularly those of women and children – in a world in which these are continually…

Carbohydrates are present on the surface of bacteria making them suitable antigen candidates for vaccine development. This thesis deals with the synthesis of two carbohydrate-based components; the capsular polisaccharide of S. aureus type 5 and teichoic acids from staphilococci and enterococci speci…

Innovation plays an essential role in firms' competitiveness and long-term success. It varies from different types, ranging from run-of-the-mill innovation that brings incremental changes to existing technologies to radical innovation that breaks from existing trajectories.

Ruzies, opstootjes en grote politieke debatten: de Russische literatuur zit er vol mee. In de nieuwe podcast ‘Schandaal en Controverse in de Russische literatuur’ gaat universitair hoofddocent Otto Boele samen met filmmaker en journalist Kay Mastenbroek in op de meest spraakmakende Russische boeken…

The aim of this thesis is to expedite and ensure the systematic accuracy of clearance scaling from adults to paediatric patients, with a special focus on drugs undergoing hepatic metabolism.

Classical statistical methods, such as p-values, are difficult for researchers to apply correctly. They for example do not allow drawing conclusions from a study early, or for extending a study with extra research groups that want to make their data available later.

Glycoconjugate vaccines are composed of microbial poly- or oligosaccharides covalently linked to a carrier protein.

In veel landen in Centraal- en Oost-Europa brak er eind jaren 1980 een periode van meer openheid aan. Wat deed dit met het toekomstperspectief van inwoners? En kunnen we iets leren uit deze periode voor onze huidige tijd? Universitair docent Dorine Schellens duikt de literatuur in om dit uit te zoek…

This thesis focuses on two processes involved in fighting infections: metabolism and immune cell motility and navigation.

In this thesis, we consider various (electro)chemical phenomena at surfaces and nanoparticles and their underlying atomistic processes, which we studied using first-principles methods such as density functional theory.

In this thesis, we have studied cell images from two types of cells, including pollen grains and the immune cells, neutrophils. These images are captured using a bright field microscope and a confocal microscope.

Large areas of space are filled by molecular clouds that consist of gas and dust grains that are the remnants of dead stars. When these clouds start collapsing, the decreasing temperature and increasing density cause gas particles to start accreting onto dust grain surfaces.

Om de klimaatcrisis het hoofd te bieden, kan een bepaalde nederigheid van de mens ten aanzien van de natuur van groot belang zijn. Tegelijkertijd kan nederigheid ook politieke overheersing in de hand werken. Hoe kunnen mensen zich op een bescheidener manier tot de natuur verhouden zonder hun vrijheid…

Dit artikel levert een bijdrage aan een groeiend aantal onderzoeken naar radicalisering. Het richt zich specifiek op het onderscheid tussen individuen die radicalisering en daardoor betrokken raken bij terroristisch geweld en individuen die radicaliseren maar niet betrokken raken bij geweld.
