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…

Leidse alumni komen op zeer diverse plekken terecht. De verhalen van onze alumni verzamelen we en publiceren we regelmatig in onze alumni nieuwsbrief en alumnimagazine Leidraad. Op deze pagina zijn al deze interviews terug te vinden. Ze brengen mooi in beeld hoe het Leidse alumni na hun afstuderen is…

In this dissertation non-parametric Bayesian methods are used in the application of robotic vision.

In this special edition of Information Polity there is a focus on the transparency challenges of using algorithms in government in decision-making procedures at the macro-, meso-, and micro-levels.

2020 is een jaar waarin we onszelf opnieuw moeten uitvinden, ook binnen de marketingafdeling van onze faculteit. Al jaren organiseren onze medewerkers kennismakingsactiviteiten zoals de Bachelor Open Dagen, Masterdagen en Proefstuderen. Vanaf maart moest alles anders.

Het Nederlands Studenten Orkest (NSO) verenigt ruim honderd van de beste student-musici van Nederland. Op 16 februari komt het orkest naar Leiden. Wij spraken met twee Leidse orkestleden en zij gaven direct een voorproefje van het concert.

Maandag jl. werden de Speckmann-prijzen uitgereikt voor het beste Bachelor leeronderzoeksverslag en de beste masterscriptie geschreven in het studiejaar 2011-2012.

Na vele jaren was het dan eindelijk zover. Het Leidse pleitteam (bestaande uit Anne van der Meeren, Heleen Kleinjans, Dries van de Voort, Sophie Vonk en Remco de Lijster en begeleiders Femke Binnendijk en Rogier Kegge) heeft de jaarlijkse pleitwedstrijd van de Vereniging voor Bestuursrecht (VAR) gew…

Tijdens haar werk voor de Europese Unie zag Sophie Vériter hoe jongeren in landen als Oekraïne en Moldavië werden blootgesteld aan Russische propaganda. Na het in kaart brengen van het EU-beleid rond desinformatie, pleit de promovendus er nu voor om de aanpak te herzien.

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.

Over the past years it has been discovered that the population of extra-solar planets is large and diverse.

The ideas underlying this thesis are that lipidomics may improve the diagnosis of liver metabolic diseases, and can provide further insights into the underlying pathophysiology of these diseases.

Quantum computing is an emerging technology, which holds the potential to simulate complex quantum systems beyond the reach of classical numerical methods.Despite recent formidable advancements in quantum hardware, constructing a quantum computer capable of performing useful calculations remains challenging.In…

The intracluster medium (ICM) is a hot, tenuous and X-ray emitting gas that pervades galaxy clusters.

This thesis focuses on amyloid proteins, a class of proteins that convert into amyloid fibrils.

In this thesis new methodologies are developed for the detection and systematic study of radio sources in the early universe. This allows us to gain a deeper understanding of the formation and evolution of galaxies, the activity of supermassive black holes, and the final phase transition of our universe:…

Almost all bacteria are enveloped by a cell wall that provides cellular protection.

Zowel met spel als politiek kunnen werelden worden geschapen waarin nieuwe regels gelden, betekenissen worden gecreëerd en mogelijkheden ontstaan voor samenwerking, strategie en creatieve oplossingen. In die zin hebben spel en politiek altijd veel gemeen gehad. Maar wat gebeurt er met deze verwantschap…

The Sun and all the stars in the night sky reside in the Milky Way galaxy. In the at-rest reference frame of the Galaxy, typical stars travel with velocities of about 100-200 kilometres per second.

In the traditional theory of linear elasticity, superposition dictates that the response of a material does not depend on the sequence of the applied mechanical actuations.

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…

Dissochaeta Blume (Melastomataceae, tribe Dissochaeteae) is well-known as a scrambling plant genus found in Southeast Asia, where it is an inhabitant of the tropical rainforests or evergreen forests.

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.

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

This thesis describes the implementation and on-sky demonstration of high-resolution integral-field spectroscopy for extreme adaptive optics systems that are used to find and characterize exoplanets.

This thesis explored the molecular pharmacological mechanisms of targeting CB2R via investigation of novel drug discovery concepts such as target binding kinetics, allosteric modulation and biased signaling.

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.

When a star is born in our Galaxy, it is quite likely that it has formed within a massive cluster, which hosts numerous high-mass stars bathing their lower mass neighbours in UV radiation.

This thesis advance our understanding and the application of molecular catalysts relevant to the reduction of oxygen as well as reduction of nitrite.

This thesis focused on the exploration of monolayer graphene as a membrane in direct methanol fuel cell (DMFC) applications, with improvements achieved through plasma exposure or damage- free chemical functionalization.

This thesis covers various applications of topology in condensed matter physics and quantum information.

The inverse electron demand Diels-Alder (IEDDA) pyridazine elimination emerged in 2013 as a new bioorthogonal reaction and constitutes a prime example of what is now known as dissociative bioorthogonal chemistry. The research described in this Thesis aims to develop synthetic strategies which enable…

This thesis is about cosmological inflation and its relation to observations.

In 2009-2010 ontstond in het westerse discours het idee van een meer ‘assertief’ China, een opvatting die China krachtig van de hand wijst. Niettemin is, vooral sinds Xi Jinping in 2012 aan de macht kwam, duidelijk dat China zijn lang gehanteerde buitenlandse beleidsdoctrine van ‘een lage profilering…
