In this work, we attempt to answer the question:

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.

One of the effects of climate change is the phenomenon of desertification, a process that occurs in semi-arid and arid areas and causes land degradation as well as vegetation loss. Due to the lack of resources, vegetation self-organizes to sustain itself by forming large-scale spatial patterns.

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

This PhD project develops and applies a GIS procedure to use legacy survey data in settlement pattern analysis. As part of the research by the LERC project (NWO, Leiden University, KNIR), legacy data produced by surveys in central and southern Italy are examined in a comparative framework to investigate…

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

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

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.

Patterned detectors are an existing technology that can be found in almost all color cameras.

In several Mediterranean regions archaeological sites have been mapped by fieldwalking surveys, producing large amounts of data. These legacy site-based survey data represent an important resource to study ancient settlement organization. Methodological procedures are necessary to cope with the limits…

Mycorrhizas are symbiotic associations between soil fungi and most plant species.

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.

Thanks to data science, we can chart and search enormous quantities of related information. This generates all kinds of new insights, for example in complex global financial structures or such societal problems as loneliness.

Patterns of paleomobility in the Caribbean were studied through an inter-disciplinary approach using a combination of archaeological, osteological, mortuary, and isotopic data.

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.

This part entails the analysis of an extensive sample of animal bone (c. 30,000 pieces) retrieved from well-defined archaeological contexts of the early period at Tell Sabi Abyad, c. 6800-6200 BC. It comprises aspects of taphonomy, ageing and osteometry, the reconstruction of the local spectrum of domestic…

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

On May 17th, Arthur Crucq succesfully defended his doctoral thesis and graduated. The Leiden University Centre for Linguistics congratulates Arthur on this great result.

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…

Vast, often populated, areas in dryland ecosystems face the dangers of desertification.

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…

We consider the propagation of electrical signals through nerve fibres.

This thesis describes how complex and real-world relevant analytical solutions can be found starting from a simple Nagumo problem posed on one or two-dimensional lattices.

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…

This thesis describes the use of the evolutionary approach in the study of language change, aiming to provide a better insight in the mechanisms that play a role in language change and to validate this approach in the field of language change.

Under what circumstances is politicization more likely to occur than others, and what impact does politicization have on government legitimacy and performance?

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.

My PhD project studies how the temporally sequential Hox gene expression is regulated during head-tail patterning of the frog embryo.

This thesis aims to demonstrate how the achromatic nature and design flexibility of liquid-crystal optics can be used to improve high-contrast imaging instruments to facilitate detailed exoplanet characterization.

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

On December 11th, Andreea Geambasu succesfully defended her doctoral thesis and graduated. The Leiden University Centre for Linguistics congratulates Andreea on this great result.

The manual analysis of remotely-sensed data is a widespread practice in local and regional scale archaeological research, as well as heritage management.

AI MAPS adopts a freedom and social well-being perspective and focuses on three themes to address key security challenges; Social disorder and public nuisances in neighbourhoods, High-impact crime, and Crowds and events.
