Frank den Hollander has received the Humboldt Research Award of €60,000. He was nominated by two German colleagues with whom he is working together for an extensive period of time. ‘The award was a complete surprise to me.'

Sewer pipes are an essential infrastructure in modern society and their proper operation is important for public health. To keep sewer pipes operational as much as possible, periodical inspections for defects are performed.

What should the EU do to support Ukraine, Belarus and Moldova? How can the European Union adapt its policies towards these countries in a very difficult and challenging geopolitical context? Ten years after its inception, the European Neighbourhood Policy (ENP) has fallen short of accomplishing its…

The invention of neural networks marks a critical milestone in the pursuit of true artificial intelligence. Despite their impressive performance on various tasks, these networks face limitations in learning efficiently as they are often trained from scratch.

Microbiome composition of the spermosphere and the rhizosphere of wild and modern bean accessions grown in an agricultural and a native soil from Colombia was characterized by metagenomics and cultivation-dependent approaches.

In the research project ‘Furthering public leadership’ the Leiden Leadership Centre collaborates with several public organisations in order to obtain academic insights on public leadership and to develop leadership in practice. This allows for evidence-based development of public leadership and direct…

Americans more often donate funds to a presidential candidate if the campaign is backed by financiers from different, recognised social groups. This is the conclusion of Leiden researcher Vincent Traag in an article in Plos One published on 14 April.

Stochastic resetting is simple enough to be approached analytically, yet modifies stochastic processes in a non-trivial way.

Tom Breukel analysed some 250 stone axes from the Caribbean and reconstructed their biographies. This increases our knowledge of production and trade in the period around the arrival of Columbus. PhD defence on 18 April.

What socio-cultural transformations did indigenous communities in the Lesser Antilles undergo from the late precolonial to the early colonial period in response to Amerindian­ European-African cultural encounters? How did Amerindian populations realign themselves in response to the colonisation…

How can we promote more durable solutions to protracted refugee situations and which roles can connectivity and mobility of displaced people play to improve protection and resilience?

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.

The increasing resistance of pathogenic bacteria to antibiotics necessitates the discovery of new medicines.

To meet the rising demand for minerals driven by the global shift to clean energy technologies, ensuring responsible and resilient supply chains is critical. Minerals like cobalt, lithium, and nickel for batteries, neodymium and zinc for wind turbines, and indium for solar panels are essential.

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.
