How do balanced lethal systems originate and persist in nature?

For optimization problems, it is often unclear how to choose the most appropriate optimization algorithm. As such, rigorous benchmarking practices are critical to ensure we can gain as much insight into the strengths and weaknesses of these types of algorithms.

The thesis addresses the long-term dynamical evolution of hierarchical multiple systems.

This minor focuses on how our thoughts, emotions and behaviour are influenced by other people, and how we influence other people.

Prof. Ton Liefaard and dr. Stephanie Rap (together with Apollonia Bolscher LL.M.) are involved in developing a training Toolkit and Manual for the project Improving Juvenile Justice Systems in Europe: Training for Professionals (JUST/2013/FRC/AG).

The master's specialisation Bioinformatics at Leiden University focuses on research, development and application of computational tools and approaches for expanding the use of biological, medical, behavioral and health data.

Schemas are knowledge structures that allow us to make efficient judgments about the world without the cost of memorizing every detail of previous experiences. It has long been known that schemas can enhance long-term memory for related information.

In the early universe, the dynamics of the Higgs field can give rise to many interesting phenomena.

When a star gets too close to a supermassive black hole, it is torn apart by strong tidal forces in a tidal disruption event (TDE).

Bacteria often experience external challenges, such as changes in environmental conditions or attacks by bacteriophages.

Scientists often need to make sense of complex systems without knowing the important parameters or even without access to all the information. A collaboration of network theorists, including Diego Garlaschelli (IMT Lucca/Leiden), has now published a review article in the inaugural issue of Nature Reviews…

In this thesis, time-lapse fluorescent microscopy plays a pivotal role in investigating functional materials within living cells as well as the migratory behaviour of neural progenitor cells.

About 15 km to the south of the ancient city of Petra, archaeologists from the University of Leiden have discovered an impressive network of ancient water conservation measures and irrigated field systems.

The experimental approach of science applied to artistic research

Hybrid zones occur where two species meet and produce offspring (hybrids). Typically, hybrids show a considerable reduction in fitness. In this thesis two hybrid zones are treated.

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.

Epithelial-mesenchymal plasticity (EMP) and tumor cell migration play an important role in cancer progression, and an improved understanding of the mechanisms underlying these concepts is essential for developing new targeted approaches.

What are the functions of the endocannabinoid system?

In this thesis, a system pharmacology approach, integrating metabolomics, pharmacology and chemical biology, was applied to understand and modulate the endocannabinoid system across different model systems (cells, zebrafish, mice and humans).

PhD defence

This research focuses on the (Quantum) Dynamics (QD) of the reactive scattering of H2 from metal surfaces.

During post-embryonic development into adults, animals face an environment that fluctuates constantly. For example, in nutrient availability, temperature, and osmolarity (e.g., salt concentration).

In this article, Lianne Visser contributed to the understanding of why collaborative governance is a challenging response to wicked problems.

It has been a long-standing mystery how complex biological structures emerge from such seemingly uncoordinated building blocks as cells and tissues, in the presence of only minimal environmental guidance.

Synthetic hydrogels that mimic the natural extracellular matrix in the biophysical and biochemical cues it provides to cells are in high demand, however the cell phenotypes as they are observed in vivo in numerous cases have yet to be attained.

On 24 September 2020, Bernardo Ribeiro de Almeida defended his thesis 'Building land tenure systems: the political, legal, and institutional struggles of Timor-Leste'. The doctoral research was supervised by Prof. A.W. Bedner. Co-supervisor was Dr. C.I.M. Jacobs.

Grasseni's contribution to this special feature on food cultures, food systems, and agriculture in Europe builds upon her ongoing project Food citizens? Collective food procurement in European cities: solidarity and diversity, skills and scale.
