TL;DR: The Gouy phase shift experienced by a light wave when it passes through a focus can be regarded as a geometrical effect arising, via the uncertainty principle, from a modification of the volume of space available for the propagation of the photon.

TL;DR: In this paper, it was shown that the modulated Langmuir wave packets with low frequency modulations (or beats) observed in the Jovian foreshock can be used as direct evidence for the L-prime + S. The modulation depth of some wave packets suggests saturation by the decay.

TL;DR: In this article, the authors investigated the causes of variations in interplanetary type II radio bursts using an analytic model which predicts the emission generated by electron beams in the foreshock regions upstream of an inter-planetary shock wave and found that the bursty nature of typical type II observations can be accounted for by a shock propagating through an inhomogeneous solar wind.

TL;DR: A biophysical model of the key aspects ofmelatonin synthesis and excretion has been developed and is found to reproduce quantitatively the key dynamics of melatonin and aMT6s, including the timing of release and amplitude, as well as response to controlled lighting and shift work.
