In organisation schemes, musical artists are commonly identified with a unique ‘genre’ label attached, even when they have affinity to multiple genres. To uncover this hidden cultural awareness about multi-genre affinity, we present a new model based on the analysis of the way in which a community of users organise artists and genres in playlists. Our work is based on a novel dataset that we ha...

As the molecular top-down causality emerging through comparative genomics is combined with the bottom-up dynamic chemical networks of biochemistry, the molecular symbiotic relationships driving growth of the tree of life becomes strikingly apparent. These symbioses can be mutualistic or parasitic across many levels, but most foundational is the complex and intricate mutualism of nucleic acids a...

The first commercial excimer laser was introduced 40 years ago by Lambda Physik (now Coherent; Santa Clara, CA). Interestingly, its developers— Bernd Steyer and Dirk Basting—were both chemists whose main goal was to develop a light source for photochemistry and dye laser pumping. As soon as excimer lasers entered the market, Lambda Physik began to investigate other possible uses for a powerful ...

Maintaining metadata quality is a a nontrivial challenge considering that the catalogue size rules out the possibility for manual curation and that the number of content providers and different delivery formats is large.
