Rotational frequency splitting of solar oscillations
Thomas L. Duvall,J. W. Harvey +1 more
TL;DR: In this article, the authors observed the sectoral oscillations of the sun to determine frequency differences produced by rotation and found that most of the solar volume rotates at a rate close to that of the surface, but also that the energy generating core may rotate more rapidly than the surface.

The robustness of seismic attenuation measurements using fixed- and variable-window time-frequency transforms
TL;DR: In this paper, the authors compare four time-frequency transforms and show that the choice of a fixed- or variable-window transform affects the robustness and accuracy of the resulting attenuation measurements.

Overlapped complex-modulated transmultiplexer filters with simplified design and superior stopbands
TL;DR: The high stopband attenuation and fast sidelobe fall-off rate make the proposed filters suitable candidates for high-speed data communication applications employing multicarrier modulation.

Reaction Product Imaging: The H + D2 Reaction
TL;DR: The differential cross section for the H + D2 → HD + D reaction has been measured using a technique called reaction product imaging, in which a photolytically produced beam of hydrogen atoms crossed a beam of cold deuterium molecules.

Proton magnetic resonance spectroscopy in the brain: report of AAPM MR Task Group #9.
TL;DR: Some fundamental issues covered in this paper are common to many forms of magnetic resonance spectroscopy and are written as an introduction for the reader toThese topics include shimming, eddy currents, spatial localization, solvent saturation, and post-processing methods.
