How do we experience electronic music? How does electronic music operate on perceptual, cognitive and affective levels? What are the common concepts activated in the listener’s mind when listening to electronic music? Why and how are these concepts activated?

From The Cognitive Continuum of Electronic Music:

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.

Science

This thesis describes a study from both a theoreticaL and an experimental point of view.

The aim of this facility is to accelerate biomedical research by providing access to advanced light and electron microscopy and by sharing expertise about sample preparation, imaging modalities, data storage and image analysis.

Atoms and molecules are the basic units of matter. If we keep dividing a bar of gold or a glass of water into smaller parts, at the end we are left with a single gold atom or a water molecule.

The principal aim of this research is to explore the confrontation between voice and electronics. These are often seen as being radically different from one another and many characteristics seem to be in opposition between them. However, they also have characteristics in common and they can influence…

This thesis revolves around the electronic spectroscopy of molecules in the laboratory and the search for the carriers of the diffuse interstellar bands (DIBs).

In this thesis the combinatorial use of bioorthogonal labelling and Electron Microscopy (EM)-based imaging techniques is explored to enable observations of specific molecular targets in their ultrastructural context within the cell.

The dissertation describes TEM experiments on heterogeneous catalysts.

New and reemerging infectious diseases call for innovative and efficient control strategies of which fast vaccine design and development represent an important element.

My research focusses on site-specific compositional and performance practices of music for organ and electronics and their musical-spatial values.

How do dissociative states affect the ability to suppress emotional distraction (in the context of a working memory task) in patients with Borderline Personality Disorder?

Milan Allan has received the Bryan R. Coles Prize at the International Conference on Strongly Correlated Electron Systems (SCES) in Prague.

In this dissertation, the synthesis and characterization of a series of iron complexes based on different ligand platforms are described.

Plant exudates appeared long time ago in the history line of life in the early Devonian. They are typical saps produced by specialized cells.

For the first time, physicists have visualized the ‘melting’ of electrons inside a special class of insulators. It allows electrons to move freely and turns the insulator into a metal and possibly later into a superconductor. Publication in Nature Physics.

Vocal learning is a trait shared by songbirds and humans. It is also a trait that is restricted by the brain rather than by a species' vocal apparatus. In this dissertation, functional MRI is employed in both species in order to explore potential common neural mechanisms underlying the ability to develop…

Huub de Groot is professor in Biophysical Organic Chemistry. With his team he works in the field of photosynthesis and artificial photosynthesis. The molecular basis for photosynthesis is formed by protein complexes and organelles that contain chlorophyll molecules. The antenna systems herein capture…

Science Magazine has published three back-to-back papers on an important discovery in solid state physics. Leiden physicist Jan Zaanen wrote a Perspective article on the subject in the same issue of 4 March.

The use of a new type of detector has generated a strong improvement in the resolution of electron microscopes. The 'low-energy electron microscope' (LEEM) can now be used for research on the thinnest possible materials. The tests with the detector represent the first result of the ESCHER project.
