The thesis is part of a bigger project, the HEPGAME (High Energy Physics Game). The main objective for HEPGAME is the utilization of AI solutions, particularly by using MCTS for simplification of HEP calculations.

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…

What are the global relationships between environmental conditions and abundance of distinct types of mycorrhizal fungi in soil and plant roots?

The goal of the project is the development of stream mining techniques for complex patterns such as graphs. We will try to extend the existing state-of-the-art techniques into two, orthogonal directions: on the one hand, the mining of more complex patterns in streams, such as sequential patterns and…

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.

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 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…

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.

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

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

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

In this thesis, we study travelling waves in stochastic reaction-diffusion equations. We extend techniques from the deterministic theory for travelling waves to apply to the stochastic version, which allows us to compute the stochastic wave speed and shape, and draw conclusions on the stability of the…

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

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

What happens to electrical waves that have to cross gaps in insulation material around nerves in the human body

Research aims: Identification of key genes involved in programming the cellular architecture of A. niger & Genetic engineering of A. niger in order to improve its secretory capacities and rheological behavior under industrial fermentation conditions.

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.

This PhD research project seeks to study the local politics in Mainland China (specifically focus on South Fujian ) by comparing with that of Taiwan——What is the specific ecology of local politics in the two regions during different eras and its role played in the political system as a whole?

Knowledge and culture subproject 3: "Visual arts and geometry" of Leiden University Centre for Linguistics

The Computer Systems, Imagery & media (CSI) research programme performs research on methods and techniques for the design, implementation and application of advanced computer systems, in particular parallel, distributed and embedded computer systems.

This PhD-research is conducted to test the hypothesis that Gutenberg and consorts developed a standardised and even unitised system for the production of textura type, and that this system was extrapolated for the production of roman type in Renaissance Italy.

The modern-day Caribbean is a stunningly diverse but also intricately interconnected geo-cultural region, resulting partly from the islands’ shared colonial histories and an increasingly globalizing economy.

PhD student Sung-Shik Jongmans of Leiden University and Centrum Wiskunde & Informatica investigated a new programming method to simplify this. On 3 March 2016, he graduated with the exceptional predicate 'cum laude' on his dissertation 'Automata-Theoretic Protocol Programming'. His results are interesting…

Tropical butterflies adapt to their environment to improve their chances of survival. The changes are triggered by hormone signals that transmit information about temperature to the butterflies' tissues. Biologist Ana Rita Mateus shows how a complex combination of environment, physiology and genetics…

The Sixteenth International Conference on Parallel Problem Solving from Nature (PPSN XVI) will be held in Leiden, The Netherlands on September 5-9, 2020. Leiden University and the Leiden Institute of Advanced Computer Science (LIACS) are proud to host the 30th anniversary of PPSN.

We have studied shape with a particular focus on the zebrafish model system. The shape is an essential appearance of the phenotype of a biological specimen and it can be used to read out a current state or response or to study gene expression.

In the first part of this thesis we study the geometry of folding patterns.

This dissertation provides a grammatical description of Ghomara Berber, a Berber language spoken in North-West Morocco by about 10.000 people. The grammar consists of a description of the phonology, the morphology and the syntax. In the appendices a number of texts and a wordlist are included. The data…

What does site patterning reveal about the social landscape dynamics across the historical divide?

PhD candidate Manon Wintgens is using an algorithm to trawl through thousands of international tax treaties. She hopes to detect a system in the dizzying interplay between countries, businesses and documents. It is a unique research project.

In this volume, Ray Jackendoff and Jenny Audring embark on a major reconceptualization of linguistic theory as seen through the lens of morphology. Their approach, Relational Morphology, extends the Parallel Architecture developed by Jackendoff in Foundations of Language (2002), Simpler Syntax (2005),…
