[1] At various altitudes in the plasmasphere, sounder pulses from the Radio Plasma Imager (RPI) instrument on the IMAGE satellite can couple strongly to protons, a process revealed in echo time delay versus frequency forms that arrive at multiples of the local proton cyclotron period tp. Lower-altitude (<4000 km) versions of two of these proton cyclotron (PC) forms were previously observed in t...

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 funadmental aspects of RF heating theory is reviewed and a summary of recent experimental results are given. All frequency regimes are covered, from very low frequency magnetic pumping to electron cyclotron resonance heating.

Organic molecular FETs provide an experimental framework for studying the band-filling dependent properties of two-dimensional metals. Here, we propose experiments to investigate the band-filling dependent cyclotron resonance, and the effect of van Hove singularities.

A new strategy is described for the determination of amino acid sequences of unknown peptides. Different from the well-known but often inefficient de novo sequencing approach, the new method is based on a two-step process. In the first step the amino acid composition of an unknown peptide is determined on the basis of accurate mass values of the peptide precursor ion and a small number of accur...
