Systems with local constraints is a new finding in recent researches on complex systems. The heterogeneous spatial interactions and the temporal dependencies among those numerous units make it difficult to describe by traditional statistical physics.

On the 23rd of March, Alessandro del Tomba successfully defended a doctoral thesis and graduated. The Leiden University Centre for Linguistics congratulates Alessandro on this achievement!

The experimental approach of science applied to artistic research

This thesis studies theoretical surface chemistry within the field of heterogeneous catalysis.

In the hunt for a vaccine against cervical cancer, fundamental knowledge about the immune system and organic chemistry have been brought together and have already resulted in a vaccine that is now being tested in clinical trials. Scientists are now working hard on an improved variant.

Complex systems can be characterized as systems in which multiple components interact with each other, often in non-linear ways. The main goal of this research will be to investigate if and how the international tax system can be defined and modelled as a complex system. Approaching the international…

We have studied the impact of particle shape anisotropy, multivalent interactions and flexibility on systems of micron-sized colloidal particles.

In this thesis we will explore the use of fuzzy systems theory for applications in bioinformatics.

Electoral Systems and Turnout: Evidence From a Regression Discontinuity Design. In this article, published on the website SAGE research methods, authors Jaroslaw Kantorowicz and Tobias M. Hlobil discuss how a Regression Discontinuity Design can be executed.

In autoimmune diseases such as rheumatism and diabetes the immune system attacks autologous proteins. Leiden researchers are trying to discover how this comes about.

On 29 January 2019, Robbert van Eijk defended his thesis 'Web Privacy Measurement in Real-Time Bidding Systems, A Graph- Based Approach to RTB system classification'. The doctoral research was supervised by Prof. dr. H.J. van den Herik.

Knowledge and culture subproject 2:

This dissertation is organised into three parts, each addressing a distinct research area related to Gibbs measures.

This thesis tackles the difficulty of predicting the liver’s clinical response to novel therapies, a challenge arising from interspecies differences and limitations of existing in vitro models.

Pathways of toxicity

We have developed a microfluidic platform for complex 3D organotypic cell cultures (so-called organ-on-a-chip systems) which are suited for integration in 96 or higher well plate format.

This interdisciplinary research project explores several adaptive machine learning methods which can give insight into the interaction between human and machine. The ultimate goal is open and natural communication between humans and AI that should result in mutual trust, cooperation and coordination…

Leids onderzoek naar bestraffing komt tot stand uit verschillende disciplines. Het onderzoeksproject kent een juridische, criminologische, sociaalwetenschappelijke en filosofische invalshoek.

Does powerlessness and dependence lead to the legitimation of the social, political, and economic status quo and of those in authority?

Cardiovascular diseases are among the most frequent causes of death in the world. The main underlying pathology of cardiovascular diseases is the development of atherosclerosis in the medium and large-sized arteries.

The key characteristic of active matter is the motion of an emergent collection (such as a flock of birds), which is driven by the consumption of energy by its active components (i.e. individual birds).

A tidal basin is an inland sea which is almost entirely enclosed by land and connected to the open sea by a tidal inlet. Through the tidal inlets interaction takes place between the tidal basin and the open sea.

We are aiming to develop novel technologies to allow better sample preparation or coupling of analytical methods to (i) analyse ultra small samples, (ii) to analyse more metabolites in a quantitative manner and/or (iii) increase the sample throughput.

Can small molecule drugs restore the immune system’s ability to fight tuberculosis by boosting autophagy?

The Collective Experience of Empathic Data Systems (CEEDs) consortium developed novel integrated technologies that support experiencing, analysing and understanding of very large datasets.

In this book liposomes are explored as delivery system for allergen-specific immunotherapy. Both cationic and anionic formulations are prepared with Bet v 1, one of the allergens in birch pollen.

Food waste is a defining inefficiency of the modern food system, with profound implications for resource use, climate change, and circular economy transitions. This dissertation examines food waste through two complementary lenses: the prevention of avoidable food waste and the valorization of unavoidable…

The first objective is to create a catalogue raisonée, i.e. a structured database that will store the main attributes of each town in a standardized format database, which will be freely accessible when completed; the second objective is to exploit theories and methods that can help us to understand…

On 25 January 2018 Yannick van den Brink defended his doctoral thesis titled ‘Voorlopige hechtenis in het Nederlands jeugdstrafrecht’ (‘Pre-trial detention in the Dutch juvenile justice system’). The doctoral research is supervised by Professor Ton Liefaard and Professor Mariëlle Bruning.

We are developing biology-driven platforms to measure metabolites based on liquid chromatography-mass spectrometry (LC-MS), gas chromatography-MS (GC-MS), and capillary electrophoresis-MS (CE-MS).

Exploring the integration of AI and quantum computing, this study adapts Knowledge Representation and Reasoning (KRR) to enhance quantum circuit simulation and optimization.

Inflammatory skin diseases such as psoriasis and atopic dermatitis can severely impact both the physical and social aspect of a patient’s life. Aberrant inflammatory responses are thought to be a major causative factor in these disorders, but an abundance of different factors contribute to the development…

To what extent is the legislation and use of pre-trial detention of juveniles in the Netherlands in compliance with international children’s rights standards?

On 17 December 2018, Dejian Kong defended his thesis 'Civil Liability for Damage caused by Global Navigation Satellite System'. The doctoral research was supervised by Prof. dr. P.M.J. Mendes de Leon.

Generations of Leiden students and academics have done archaeological research into the early medieval history of Oegstgeest. This makes this old settlement one of the best-documented sites from that era. In a new book, Leiden researchers take stock.

This thesis focuses on two processes involved in fighting infections: metabolism and immune cell motility and navigation.

Detecting and combatting crime is becoming increasingly complex. Security is high on the national and international agenda. The master’s programme Crime and Criminal Justice in Leiden provides the skills to face these challenges.

Cardiovascular diseases are the primary cause of death in the world with atherosclerosis as primary underlying cause.
