The Copenhagen interpretation of quantum mechanics states that a measurement collapses a wavefunction onto an eigenstate of the corresponding measurement operator.

In this research group, headed by Prof. Erik Danen, the aim is to unravel cellular signaling mechanisms in normal and diseased cells, with a long-standing interest in cell adhesion signaling. In complex multicellular organisms such as ourselves, a division of labor emerges where different tissues and…

To be able to measure small forces or small deviations from Boltzmann, the external vibrations at the resonance frequency must be very low. To achieve this, we have developed a very soft vibration isolation system and combine it with several other measures to reduce vibrations in our dilution refrigerators.…

If you replace the standard hydrogen atoms in ice with a heavier variant, something odd happens. The volume occupied by the molecules increases by 0.1 per cent. Leiden chemist Jörg Meyer and his colleagues have created a theoretical model that describes this behaviour. Their research appeared on the…

Somatic symptoms, such as pain, itch, and fatigue have been shown to have a bidirectional relationship with mental symptoms. Although acute somatic symptoms serve some adaptive properties, chronic symptoms can instead lead to interference in daily activities and lower quality of life.

Plant Sciences' contribution to the Development & Disease research theme is to unravel the processes that allow plants to adapt to changing abiotic and biotic environmental conditions or stresses, with the aim to contribute to the sustainable production of food, flowers and bio-based products using…

The aim of the research programme is to provide insight into the cognitive processes and brain mechanisms that underlie reading, arithmetic and learning in general.

In this article, Lydie Cabane, Assistant Professor at the Institute of Security and Global Affairs, and Martin Lodge address the question of how to manage banking crises, a question that has gained prominence since the banking crisis of 2007-2009. This article sets out the rationale for regulating for…

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.

Which immune mechanisms are involved in host defense against Staphylococcal infection?

How does the photoregulation mechanism work in detail?

What is the mechanism of action preceding a physiological effects induced by metallic nanoparticles?

Why is Crossnational and Cross-cultural agents such as Henrich Carloff and Willem Leyel important when studying Early Modern expansion?

The CIGR comprises research groups from the Institute of Biology Leiden (IBL), the Leiden Institute of Chemistry (LIC), the Leiden Academic Centre for Drug Research (LACDR) and the Leiden Institue of Physics (LION).

In this thesis we have discussed several parameters that affect the electrochemical conversion of enviromentaly harmful molecules such as nitrates and carbon dioxide to more valuable and less deleterious compounds, in order to cast light onto the mechanism of the reaction to achieve an efficient and…

As an alternative to the diving board shaped force sensor, we are now developing a magnetically levitated small superconducting particle – or ‘Lead Zeppelin'' – as our mechanical resonator. We explore routes towards detection of gravity between small objects.

In this thesis, we aimed to better understand the underlying mechanisms involved in TNBC progression and metastasis formation and discover new targets to reduce breast cancer related deaths.

Solar energy harnessed by plants and algae has great potential to be converted into biofuels for future generations.

This research focuses on a historical/social analysis of a selected corpus of novels from modern Turkish literature which have the common theme of migration from Anatolian towns and villages to Istanbul, and the immigrants’ struggle in this city against various exclusion mechanisms.

This dissertation is an experimental study of laser-generated, atmospheric pressure, transient toroidal helium plasmas.

Given the accelerating appearance of antimicrobial resistance, there is an urgent need for more fundamental research into novel antibiotic strategies. The work in this thesis helps to address this global problem by developing new antibiotic compounds, inspired by the antibacterial mechanisms of the…
