The AT-Hook Nuclear Localized 15 (AHL15) gene belongs to a plant-specific gene family of DNA-binding proteins. Overexpression of AHL15 in Arabidopsis thaliana delays developmental phase transitions whereas its loss of function causes a slight acceleration.

This thesis investigates the application of deep learning techniques in image analysis across various domains, focusing on four main themes: feature extraction, classification, segmentation, and integration, demonstrating the transformative potential of these technologies.

Na een zeer succesvolle eerste editie kondigen we met genoegen de tweede Leiden eLaw Summer School aan over ‘Regulating AI in the EU Digital Market’. Deze vindt plaats van 23 tot en met 27 juni 2025, zowel fysiek in Leiden als online.

Simone van der Hof heeft op 3 en 4 februari 2020 aan het Käte Hamburger Kolleg 'Recht und Kultur' van de Universiteit Bonn deelgenomen aan het 2-daagse symposium Digital Transformation In Law & Society: Comparatve Perspecties On Family And New Media.

The largest structures in the Universe are clusters of galaxies. Each can contain hundreds to thousands of galaxies.

In de masterspecialisatie Visual Ethnography leer je de kneepjes van het vak om etnografisch onderzoek met audiovisuele methodes te doen.

There is an urgent need for more physiologically relevant cell culture methods to guide compound selection in pre-clinical stages of the drug development pipeline.

Over the past two centuries, socioeconomic development has improved material living standards but has also intensified environmental pressures, including climate change and biodiversity loss.

Hoogleraar Yra van Dijk heeft een subsidie toegekend gekregen van NWO voor internationaal onderzoek. De subsidie Internationalisering in de geesteswetenschappen is bedoeld om samenwerking tussen Nederlandse en buitenlandse onderzoeksgroepen op het terrein van de geesteswetenschappen te bevorderen.

This thesis comprises the development of reproducible synthesis procedures for two-dimensional materials (composed of boron, nitrogen and carbon) on different metallic surfaces.

Stellar feedback is a crucial ingredient in the evolution of galaxies.

Morshed Mannan presenteerde onder andere zijn artikel dat deel uitmaakt van zijn proefschrift met de titel ‘Everything Old is New Again: Evaluating the Legal and Governance Structures of Emergent Protocol Cooperatives’.

Heterogeneous catalyzed processes are highly significant to the chemical industry. Dissociative chemisorption (DC) of molecules on surfaces is always considered as a step with a high degree of rate control for heterogeneous catalysis.

This thesis describes the Multi-site All-Sky CAmeRA (MASCARA), which consists of two small robotic telescope designed to detect exoplanets around the brightest stars in the sky.

Hoe worden nachtruimtes verbeeld, geproduceerd, ervaren en verteld door migrantengemeenschappen in Europa? Dit onderzoeksproject onderzoekt deze vraag in acht Europese steden: Aarhus, Amsterdam, Berlijn, Cork, Galway, Lissabon, Londen en Rotterdam.

The thesis introduces three methods for high-dimensional prediction problems in the biomedical field. The methods make use of empirical and variational Bayes in the estimation.

The upscaling of Life Cycle Assessment (LCA) data is recognized as one of the main challenges in the ex-ante LCA of emerging technologies. This challenge arises since industrial-scale system specifications for these technologies are unknown and industrial data is lacking.

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…

We present an extensive study of methods for exactly solving stochastic constraint (optimisation) problems (SCPs) in network analysis. These problems are prevalent in science, governance and industry.

Circumstellar discs are the reservoirs of gas and dust that surround young stars and have the potential to become planetary systems.

Metals surfaces form a group of effective catalysts for the reaction of small molecules such as hydrogen (H2).

OB associations are loose groups of young, massive stars. They constitute the last stage of the massive starformation process, and the context in which new stars are formed.

Tot nog toe was van de Indische schrijfster Dé-Lilah, pseudoniem van Lucy van Renesse-Johnston, slechts één foto bekend. Onlangs vonden onderzoekers Rick Honings, Nick Tomberge en Olf Praamstra – verbonden aan het Leiden University Centre for the Arts in Society (LUCAS) – in de Leidse Digital Collections…

This thesis develops a method for direction dependent calibration of the ionosphere in radio interferometric data.

Over several decades, a variety of computational methods for drug discovery have been proposed and applied in practice. With the accumulation of data and the development of machine learning methods, computational drug design methods have gradually shifted to a new paradigm, i.e. deep learning methods…

In this thesis, bioorthogonal chemistry is combined with correlative light-electron microscopy to selectively label and study pathogenic intracellular bacteria within the host immune cell.

De Universiteit Leiden stimuleert studenten om hun antropologische kennis te verdiepen en na hun bacheloropleiding door te gaan met een masteropleiding.

From the 1920s on, popular music in Southeast Asia was a mass-audience phenomenon that drew new connections between indigenous musical styles and contemporary genres from elsewhere to create new, hybrid forms. This book presents a cultural history of modern Southeast Asia from the vantage point of popular…

JUSTREMIT en het Institute of Security and Global Affairs van de Universiteit Leiden organiseren op 12 en 13 oktober een conferentie over Global Regulatory Regimes and Remittances. Academici, mensen die werken binnen de regelgevingssector en vertegenwoordigers van internationale financiële instellingen…

n this thesis we study curves. In the first half, we study moduli spaces of curves and Gromov-Witten invariants, certain kinds of curves counts. We employ logarithmic geometry for this.
