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.

Our world is shrinking, or at least our electronic devices are. From PCs to mobile phones: everything is smaller and thinner. The smaller the chip, the better it can conduct electricity and pass on information.

In deep reinforcement learning, searching and learning techniques are two important components. They can be used independently and in combination to deal with different problems in AI, and have achieved impressive results in game playing and robotics. These results have inspired research into artificial…

What are the advantages of speaking a second language? Why do some people find it easier to learn a second language than others? Does a dialect count as a first language? On 20 May, Leiden University is organising an English-speaking public symposium on bilingualism: Twee Talen - één BeTalen.

LUMC researchers are looking for factors that point to illness at an early stage.

Is there extra-terrestrial life out there? It now looks as though we can sketch out an answer to this enduring question. Leiden Observatory is helping to build new instruments to find the most promising exoplanets.

Leiden physicist Carlo Beenakker has received an honorary doctorate from the Bogoliubov Institute for theoretical physics in Kiev.

The main focus of this thesis is the behaviour of two-dimensional materials, namely (anti)-ferromagnetic materials in the first two chapters, which show topological phases, and energetic square ice in the third and fourth chapter.

Self-assembly offers a promising route to create complex structures and materials using simple building blocks. Through, colloidal self-assembly, we can understand the governing principles of the self-assembly process and unlock its potential in diverse applications in materials science, photonics and…

In order to test theoretical expectations concerning individual decision-makers' search in response to negative performance, Joris van der Voet conceptually disentangles problem-defining and solution-generation as two distinct search objectives.

Apps that can precisely identify shards, coins or heel bones: archaeology has embraced artificial intelligence. Alex Brandsen is working on a search engine that scans vast quantities of text from an archaeological viewpoint.

National and international actors have attempted to provide accountability for the events at Srebrenica in July 1995. This research project aims to draw lessons learned from those multiple efforts in assessing whether securing a measure of ‘justice’ for the victims has been successful and how national…

This book investigates how the rulers of the Habsburg world empire developed and implemented a central maritime policy for the Netherlands and appointed an admiral of the sea or admiral-general for that purpose.

Op welke manieren kan inclusieve communicatie ervoor zorgen dat mensen zich welkom voelen? Hierover ging het D&I-symposium van Universiteit Leiden.

Minister Wiersma heeft circa vijftien informatieverzoeken, over de hoeveelheid vee en de locaties van stallen van veehouders stilgelegd. Universitair hoofddocent Staats- en bestuursrecht, Annemarie Drahmann, stelt in het NRC dat de wet verplicht dat dergelijke milieugegevens openbaar moeten worden g…

Het Hof van Justitie van de EU maakt duidelijk dat de doorlooptijd bij asielaanvragen in Nederland te traag verloopt. Mark Klaassen, universitair docent migratierecht, zegt in Dagblad Trouw dat personeelstekorten en/of achterstallig onderhoud bij de IND geen reden kunnen zijn voor het verlengen van…

In this thesis, we examine various systems through the lens of several numerical methods.

Ambient sound is a standard term used by sound practitioners to denote the site-specific background sound component that provides a characteristic atmosphere and spatial information in a sound work.

With the rise of multi-drug resistant bacterial pathogens, the possibility of a post-antibiotic world is quickly becoming reality.

Describing almost 1400 maps of Africa in three months. It’s no small task that student assistants Artemis Mantheakis and Beatriz Veiga have been working on within the joint ASCL-UBL Africa Maps Project. The project’s aim is to describe and catalogue a 20th-century map collection of the library of the…

PhD defence

Since the 16th century, religious concerns have motivated the study of Old English and its speakers. In the 19th century, scholars turned to the study of Old English literature in particular to find traces of pre-Christian, ‘Germanic’ religion, as discussed in Eric G. Stanley’s seminal work The Search…

Het demissionair kabinet zet een koerswijziging in ten opzichte van eerdere ‘stille diplomatie’ strategie. Deze koers bevat o.a. een inreisverbod voor twee extremistische ministers Smotrich en Ben-Guyir. Wim Voermans, hoogleraar Staatsrecht, zegt in de Volkskrant’ dat het kabinet hiermee een belangrijk…
