Geometric phases lead to a nontrivial interference result when an electron's different quantum mechanical paths choices encircle a magnetic coil in an Aharonov-Bohm experiment.

Which features characterize speakers’ voices, and how are these features determined by what a speaker is saying?

Fleur Visser was awarded a Veni grant by the Netherlands Organisation for Scientific Research (NWO). She is one of seventeen promising young Leiden scientists, who get the opportunity to develop their own ideas over a period of three years. Veni-funding is part of NWO's Talent Scheme, concerning…

This thesis explored the molecular pharmacological mechanisms of targeting CB2R via investigation of novel drug discovery concepts such as target binding kinetics, allosteric modulation and biased signaling.

On October 31st, Margarita Gulian succesfully defended her doctoral thesis and graduated. The Leiden University Centre for Linguistics congratulates Margarita on this great result.

Anthropogenic noise has been shown to affect marine animals in various ways, this may have fitness consequences at individual and population level. This thesis aims to increase insight into the quantification of sound-induced behavioural responses that are relevant to fitness, and into factors that…

An international research team consisting of Katharina Riebel as leading PI and two international collaborators were awarded a Human Frontier Science Program grant for their proposal ‘Seeing voices’: the role of multimodal cues in vocal learning.

This is an Erasmus+ International Credit Mobility project of Leiden University’s Faculty of Science with the Anton de Kom University in Suriname.

Evolutionary and ecological interactions affect species on genetic and phenotypic levels. This theme aims to understand these processes at multiple levels: from molecules to genomes to populations and to communities. Our research focuses on evolutionary responses to anthropogenic change, the role of…

This dissertation aims at discussing the nature and the linguistic factors assumed responsible for speech intelligibility problems of Sudanese learners of English.

If, as the works of John Cage suggest, there is “no such thing as silence,” then what are the markers that show us we are experiencing silence? - what are the performative cues during musical silence? - what are the auditory and visual bookends of silence in performance, i.e. what anticipates and…

This thesis investigates the connection between tonal realization and tone change (tone sandhi) in Wenzhou Chinese, and whether and how such a connection is conditioned by prosodic structure and focus marking.

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 Ph.D. thesis, we characterized two novel upstream regulators of JUB1, HB40, and HB22, in Arabidopsis thaliana. In Chapter 2, we described functions of HB40 in modulating growth and development via the regulation of JUB1 and GA inactivation genes GA2OXs.

Heart failure is a major health care problem with high mortality.

How can we understand the drum-set – and thus drummer – as technological? How have technological developments affected change in drum-set performance and drum-set construction? Are the relationships between new technologies and the drummer symbiotic, or one way? To what extent are instruments and (reactive)…

Intrigued by the way cells autonomously regulate their fate, we strive to understand and visualize cellular processes as the basis of Cell Signaling.

Speech Prosody 2024 includes several poster sessions, the description of which you can find below.

An overview of the research at the Cancer Dug Target Discovery group.

Across many decision-making tasks, people and animals systematically repeat (or alternate) their choices - even when the choices they make are intrinsically uncorrelated. This phenomenon (also known as 'sequential effect' or 'choice hysteresis') has been known for at least a century, and may be a stable…

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…

We investigate the processes underlying the patterns. We aim to explain biodiversity by investigating the distribution, function, development, and evolution of body forms, as well as physiological and behavioural variety among species. We collaborate with those specialized in describing, archiving,…

In his dissertation Gabriel Paiuk explores the variable ways in which what is heard is formed. To address this, he postulates a novel concept of sound image in a post-anthropocentric context in which both mind and material artefacts are instances across which the image occurs, rather than hosts on which…

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…

In this article, Vanessa Newby, assistant professor at the Institute of Security and Global Affairs, discusses credibility in peace operations. This article argues that credibility in peace operations must be built for both deterrence and cooperation purposes.

Bacterial chemosensory arrays are protein assemblies that are the key structural and functional component for motile bacteria to sense their internal or environmental chemical signals.

Smartphone behaviors are so common but how does the brain generate this behavior? The Cognition in the digital environment laboratory (CODELAB) investigated the brain activity surrounding smartphone interactions with the help of Artificial Intelligence. According to their research, the brain fluidly…

PURPOSE: In the present study we investigated the root-cause of an interference signal (100-200 nm) of sugar-containing solutions in dynamic light scattering (DLS) and nanoparticle tracking analysis (NTA) and its consequences for the analysis of particles in biopharmaceutical drug products.

We consider the propagation of electrical signals through nerve fibres.
