We investigated dissolved organic matter (DOM) metabolism by employing plug-flow biofilm reactors and ultra– high resolution mass spectrometry of DOM isolated by C 18 extraction in two forested stream ecosystems, a low DOM tropical stream sampled at baseflow and a higher DOM temperate stream sampled during a storm. On passage through the bioreactors, DOM… (More)
This short review summarizes recent and projected advances in Fourier transform ion cyclotron resonance mass spectrometry instrumentation and applications, ranging from petroleomics to proteomics. More details are available from the cited primary literature and topical reviews.
The ARK (ArchivalResource Key)naming scheme is designed to facilitate the high-quality and persistent identification of information objects. A founding principle of the ARK is that persistence is purely a matter of service and is neither inherent in an object nor conferred on it by a particular naming syntax. The best that an identifier can do is to lead… (More)
is widely regarded as the founding figure of the field known as "ubiquitous computing." First enunciating his ideas in 1988, he envisaged a world with large numbers of wireless computing devices per person, with the devices spanning wide ranges of size and capability. In his vision, ubiquitous computing is inspired by "social scientists, philosophers, and… (More)
