The results of the investigations by citizens are used in an innovative research project that investigates the potential of machine learning and automated detection in archaeology.

This dissertation explores how we can make anomaly detection—identifying unusual or faulty behavior in complex systems—more trustworthy and effective, with a focus on smart manufacturing.

Structural variants (SVs) are the hidden architecture of the human genome, and are critical for us to understand diseases, evolution, and so on.

Single-molecule spectroscopy has become a powerful method for using organic fluorescent molecules in numerous applications.

In the era of big data, extracting insights from complex datasets is a key challenge. This thesis demonstrates the superiority of graph-based methods over traditional clustering (e.g., k-means, DBSCAN) and outlier detection for analyzing high-dimensional and noisy data.

Our group explores the larger domain of quantum measurement. In particular we investigate two themes that are closely connected: The detection of specially prepared quantum states of light and understanding and characterizing quantum photon detectors.

On the 10th of November, Martin Kroon successfully defended a doctoral thesis. The Leiden University Centre for Linguistics congratulates Martin on this achievement!

Miles Kellerman, Assistant Professor at Leiden University, argues in a new article that governments should consider empowering financial crime bounty hunters by creating Licensed Detection Agents to address structural failures in current systems for detecting financial crime.

On 8 January 2020, Jelmer Brouwer defended his thesis 'Detection, detention, deportation'. The doctoral research was supervised by Prof. J.P. van der Leun and Prof. M.A.H. van der Woude.

Detecting nanoscopic objects plays an important role in nanoscience in particular, in the rapidly growing field of nanobiology. The forebear to modern super-resolution microscopy for single molecule investigation, is fluorescence microscopy.

In this thesis, we describe the latest advances in SQUID-detected Magnetic Resonance Force Microscopy (MRFM).

In this project we develop algorithms to automatically detect a particular type of archaeological sites in satellite images of the Alps.

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.

Deepfakes are videos that have been manipulated to replace one person’s likeness with that of another. They can be difficult to distinguish from authentic videos. In our study, we found that people who score high on conspiracy thinking and people who use social media more are better at distinguishing…

Generally the data from remote sensing surveys - the scanning of the earth by satellite or aircraft in order to obtain information about it - is screened manually in archaeology. However, constant monitoring of the earth's surface causes a huge influx of data of high complexity and high quality. To…

So far it has been impossible to compare large sets of syntactic constructions in large sets of languages systematically and automatically. The online availability of parallel text corpora and software tools to align, enrich, search and analyse them has the potential to make automatic massive systematic…

LUCL PhD researcher Marijn van Putten has received a Veni grant by the science funding agency NWO.

Cardiovascular diseases (CVDs) are the leading global cause of mortality. Endothelial dysfunction, an early reversible stage of CVD development, is marked by decreased nitric oxide production linked to Ca2+ influx in endothelial cells.

Homicide engenders broad moral concerns in society, and its aftermath can be understood as a barometer for criminal justice policy. Of all homicides committed, however, only some lead to arrest, to prosecution and ultimately to conviction in court.

The major and ultimate aim of metabolomics is to obtain an answer to a specific biological or clinical question.

Ariane Briegel wants to use bacteria to detect cancer at an early stage. Together with postdoc Alise Muok, she is developing a method to quickly and cheaply test the urine of patients for the presence of suspicious molecules. They receive a grant of approximately 150,000 euros from the Dutch Cancer…

Leiden and Jülich researchers discovered an elegant and simple approach to improve the sensitivity of graphene biosensors. These so-called ‘next generation graphene electronic biochemical sensor devices’ are able to detect very low amounts of HIV DNA thanks to their very low electronic noise.

How did we come into existence? Are we alone? These questions have driven humans for centuries.

How should the Quran be read? The manuscript of this holy book makes different interpretations possible. Researcher Marijn van Putten has been awarded an ERC Consolidator Grant of two million euros to explore centuries-old recitations.

Can a robot rekindle the waning interest in Buddhism in Japan? University lecturer Peter van der Putten researches the philosophical and social questions related to artificial intelligence. He also investigates whether computers and robots can take over creativity, emotions and other human characteristics.…

It's pretty hard to spot a single 5 nanometer particle. Leiden physicists pulled it off by turning a 120 nm gold rod into a detector.

With the emergence of social media platforms such as Twitter, Facebook and Instagram, it’s easier than ever to share information. Including disinformation. During his PhD computer scientist Xueqin Chen developed a new way to recognise fake news and predict how messages spread within online social networks…

A team of scientists, including Leiden Astronomer Alice Booth, has discovered silicon monosulfide molecules in the dust disk around a young star. Such molecules indicate planet formation. The team made the discovery using the ALMA telescopes. This method provides an alternative when direct observation…

NWO honoured Leiden psychologist Jeffrey Durieux with a Research Talent Grant for early dementia detection by identifying differences in resting-state networks.

Over the past decades within the European Union (EU), economic proliferation and globalisation have resulted in an increase in transboundary waste transportation. Although waste trading can often have positive economic and environmental impacts by repurposing natural resources within industrial sectors,…

For his PhD project, computer scientist Manolis Fragkiadakis is developing a tool that can compare videos of sign language corpora. This would make it possible to detect differences between sign languages and prevent translation errors. Ultimately, the tool could be used to compare sign languages from…

Optical detection of a single electron using a single molecule has never been done. Leiden physicist Michel Orrit and his team have now identified a molecule that is sensitive enough to detect an electron at a distance of hundreds of nanometers. The results are published as a cover article in ChemPh…
