Studievoorlichting

Computational thinking, programming, and algorithms form the basic of many of the things that are shaping our world, the way we work, interact, organize ourselves, and even spend our free time with social networks, streaming media, and games. And this transformation is far from being complete, it is…

This thesis deals with the use of sound in interactions in the context of participatory systems and data sonification. We investigate an interactive environment where participants perceive information of the data through sound elements.

Sinds september zijn er zeker elf mensen opgepakt in verband met, of veroordeeld wegens bedreiging van demissionair premier Rutte. Dit past binnen de trend dat het aantal geregistreerde bedreigingen tegen politici de laatste jaren is gestegen. Jelle van Buuren, universitair docent bij ISGA, stelt in…

VALUE (Videogames and Archaeology at Leiden UnivErsity) publiceert een nummer over het snijvlak tussen archeologie, erfgoed en videospellen. In dit nummer komen wetenschappers en game designers samen om te laten zien hoe deze beroepsgroepen samen kunnen werken.

Een aantal gemeenten die nepaccounts gebruiken om op onlineplatforms en sociale media informatie in te winnen over hun burgers, zegt niet te willen stoppen met die omstreden praktijk. Dat schrijft de Volkskrant op basis van een inventarisatie.

The extensive use of electronic communication channels and other devices has opened new possibilities for collecting data on human behavior. This information is sometimes openly accessible, but largely part of administrative registration systems that are not open to the broader public. The data provides…

Endocannabinoids are lipid messengers that modulate various physiological functions by activating the cannabinoid CB1 and CB2 receptors. While the metabolism of endocannabinoids and their action at the CB receptors is fairly well studied, the molecular mechanisms governing their release and transport…

This thesis mainly focuses on cross-modal retrieval and single-modal image retrieval via deep learning methods, i.e. by using deep convolutional neural networks.

Protoplanetary disks are the gas and dust environments where planetary systems form around young stars. Using observations from the Atacama Large Millimeter/submillimeter Array (ALMA) this thesis analyses the gaseous molecular reservoir, using multiple tracers to resolve the 3D structure of protoplanetary…

This thesis provides explicit expressions for the density functions of absolutely continuous invariant measures for general families of interval maps, that include random maps and infinite measure transformations, not necessarily number systems.

Explaining treatment response variability between and within patients can support treatment and dosing optimization, to improve treatment of individual patients.

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.

Despite being the second largest transmembrane protein family after GPCRs, the SLC superfamily has only gained significant attention in early drug development over the past decade.

In this thesis, we aim to shed light on the diverse and often opposing roles of integrin α3β1 in cancer.
