In condensed matter systems electron-electron interactions, negligible in everyday metals, can dramatically alter the electronic behavior of the system. Examples of such altered behavior include high-temperature superconductivity and modulation of the electron density.

How do balanced lethal systems originate and persist in nature?

Apart from humans, animals play a pivotal role in travel literature.

What are the humanities? As the cluster of disciplines historically grouped together as “humanities” has grown and diversified to include media studies and digital studies alongside philosophy, art history and musicology to name a few, the need to clearly define the field is pertinent.

Thermodynamics is one of the founding scientific pillars that has helped us better understand heat engines, biology, ecosystems, and even black holes. While it fundamentally describes large systems by examining the bulk behavior of their constituents, it is anchored in the statistical equivalence of…

The research groups within the biological, soft and complex systems research area study the physics of a broad range of biological and soft materials. This spans both experimental and theoretical research.

In this thesis, we have studied the potential of the zebrafish larval model in studying the ECS, as a complementary model to the existing rodent models.

This book explores the boundaries of the category of gender and their theoretical significance within the framework of Canonical Typology.

The ambition of the Medical Systems Biophysics and Bioengineering group led by Alireza Mashaghi is to develop and use physics and engineering concepts and tools for pathophysiology, diagnostics and therapy.

We study the physics of a broad range of biological and soft materials

Grammatical gender is famously the most puzzling of the grammatical categories. We have a solid typology of gender systems, yet exciting and unexpected patterns keep turning up which defy easy classification and straightforward analysis. Some of these question, stretch or threaten to cross the outer…

At Leiden University we believe it is important that you receive the right kind of support in your choice of study and while you study. This is why we use what we call the ‘Leiden study system’ to help you make a success of your study from start to finish.

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…

Discovery and development of Central Nervous System (CNS) drugs is hampered by high attrition rates.

In art history, performance is categorized as performance art and defined as live-act. However, performance is no longer conceived of by artists as live-act only.

Research into research improves the academic system. CWTS studies and evaluates the academic system in various ways. One way is to provide information on the productivity and impact of academics by documenting how many publications they or their universities produce and how often these publications…

To increase clinical success rate of drugs, a better understanding of drug action mechanism and disease dynamics is required. Metabolomics, which studies small molecules involved in biochemical processes in organisms, has shown to be a useful tool for this better understanding.

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…

Following their application to system biological models, control theory techniques have further potential to aid in the understanding and application of quantitative systems pharmacology models.

How can we explain that Caribbean small states have the most stable two-party systems in the world, while Pacific small states have either very weak parties or no parties at all?

Neurodegenerative diseases, including Parkinson’s disease (PD), are increasing in prevalence due to the aging population. Despite extensive study, these diseases are still not fully understood and the lack of personalised treatment options that can target the cause of the diseases, rather than the symptoms,…
