Chapter 1,contains the numerical verification of the Birch and Swinnerton-Dyer conjecture for hundreds of Jacobians of hyperelliptic curves of genus 2, 3, 4 and 5.

Cardiovascular diseases are still a major concern for the global health.

This thesis focuses on important life history traits and their trade-offs using two hexapod models. Particularly, the trade-off between immune defense and embryonic developmental speed is a central theme of this study.

Fundamental understanding of molecular reactions on metal surfaces is important for improving heterogeneous catalysis.

Several techniques are explored for going beyond the born-oppenheimer static surface model for molecule-surface reactions.

This study aims to explore the use of a behavioral-design-based approach in simulating patient flow through EMTs. It provides a dynamic behavioral simulation model to assess the interactions between patients, staff members, and the related dynamic movements/interactions with the health care facility,…

Assistant Professor Vedran Dunjko and his team received a gift from Google to support their quantum research. The research focuses on whether quantum computers can provide new ways of understanding the mysteries of high-energy physics.

Cosmologists have many possible models for the Universe, of which only one can be true. A new flowchart will eliminate some of them when two specific Universe features are accurately measured. Publication in Physical Review D on 7 November.

Dave R. Stikkolorum, Michel R.V. Chaudron, Oswald de Bruin won the Best Paper Award of the Model Gamification Contest at the ACM/IEEE Models 2012 Conference for their paper: The Art Of Software Design, a Video Game for Learning Design Principles.

Agricultural foods naturally vary in their detailed internal structure. To facilitate early detection of health hazards due to contamination or disease, predict maturity and minimize wastage, it is critical to take into account the internal characteristics of each individual product, as these enable…

This project aims to answer the following questions: how did the landscape and geography of the local surroundings of Chalcis impact medieval to early modern productivity, habitation, mobility and interaction in a wider sense? And where are such changes and continuations still visible in the landsca…

The Maker Space in Huizinga 0.11f is a creative environment where students and researchers can access a professional 3D scanner, 3D printer, and a camera-based scanning system for high-quality text and image digitisation.

Tuberculosis (TB) is associated with 1.5 million deaths annually. There is a need exists to optimize both current as well as novel antibiotic combination treatment strategies to improve the effectiveness and safety of treatments against TB.

The financial system needs complexity theory to predict economic crises like the 2008 meltdown. An international team of scientists, including Leiden physicist Diego Garlaschelli, state this in a paper published in Science on February 19th.

Professor Carlo Beenakker has been awarded a FOM Projectruimte subsidy to build a theoretical model of a majorana gun, a very promising instrument for quantum computers.

What if you could watch a CT scan live, instead of analysing the images afterwards? If it is up to the Leiden mathematician Jan-Willem Buurlage, that will soon be a reality. He is developing methods to make the algorithms behind 3D scans faster. Quite a challenge: ‘Just like mathematicians, computers…

The ambition of the Metabolomics and Analytics Centre led by Thomas Hankemeier is to develop innovative analytical strategies for metabolomics-driven health monitoring and systems biology studies. Understanding the intricate balance between health, disease and adaptation to challenges relies on the…

SAILS likes to occasionally organise workshops about topics that relate to our programme. On this page you can find more information about previous workshops.

The ability to create objects and structures with our hands has been essential to human development. This ability is something modern society is at risk of losing. Leiden archaeologists gather knowledge about ancient processes of ‘making and creating’ over the centuries, knowledge that helps our current…

Since 2013, the National Natural History Museum of the Netherlands, Naturalis Biodiversity Center, is unearthing the largest bonebed of the horned dinosaur Triceratops discovered so far. In order to answer questions about sedimentology, taphonomy and palaeobiology, palaeontologists and geologists collaborated…

Do you recall all those drugs that were hastily proposed as potential treatments for COVID-19? In the event of a future pandemic, the goal is to offer an effective treatment more quickly and efficiently. To achieve this, a team led by Coen van Hasselt is developing a platform that can speed up the process…

Cardiovascular disease is the leading cause of death worldwide.

The main methodological aspects of the use of stepwise LCA estimators under different circumstances.

Experts from several disciplines have raised concerns about the use of seemingly precise models to guide policies in matters as complex as the current Covid-19 pandemic. 22 scholars wrote down five principles on how to responsibly use scientific models. This comment was published in Nature on 24 June…

The Faculty of Archaeology experiments with innovating their teaching methods, using 3D scans and visualisation technology to enable active learning. 'It makes archaeological material more accessible. Especially when it comes to fragile materials, it allows nearly anybody to analyse them.'

Researchers from the Leiden University Medical Center (LUMC) have developed an AI model that accurately predicts the risk of endometrial cancer recurrence.

Anthropologist Rodrigo Ochigame studies how AI is changing the practice of scientific research. From astrophysics to mathematics to climate science, they find that the adoption of new AI models is raising questions about what counts as reliable scientific evidence.

A full overview of all loans and debts between banks would help preventing a new financial collapse. But banks do not provide this information. An econophysics model by Diego Garlaschelli and collaborators reconstructs the most probable situation and finishes first place in two independent tests.

Archiving Medieval and Post-Medieval Archaeological Fieldwork Data from the Eastern Mediterranean (600-2000)

The precolonial inhabitants of the Caribbean islands communicated, travelled, and exchanged objects and ideas along an expansive inter-island network. New methods of computer modeling shed light on these networks. Emma Slayton is set to discuss her work on this topic at her Defense on the 12th of Se…

A new AI model will soon be able to predict the risk of infection in postoperative patients. This will allow healthcare providers to take preventive measures and detect complications at an earlier stage.

A new study in Nature Plants has explored the most important organising principles that control vegetation behaviour. The insights from this study can be used to improve predictions on climate change. Leiden scientists Peter van Bodegom and Nadia Soudzilovskaia participated in the study.
