TL;DR: In this article, the evolution of the Langmuir and ion-acoustic wave spectra is investigated numerically in time, position, and wave number space, and spontaneous emission is considered.

TL;DR: A simple model is constructed for the electric fields in the collapsing wave packets found in 3D simulations of driven and damped isotropic strong Langmuir turbulence, accounting for the distribution of wave-packet shapes observed in the simulations, particularly the predominance of oblate wave packets.

TL;DR: In this article, the first test of whether stochastic growth theory (SGT) can explain the detailed characteristics of Langmuir-like waves in Earth's foreshock was presented.

TL;DR: A new approach, based on a Markov transition matrix, is proposed to explain frequent sleep and wake transitions during sleep, and shows that the statistics of sleep can be constructed via a single Markov process and that durations of all states have modified exponential distributions, in contrast to recent reports of a scale-free form for the wake stage and an exponential form for

TL;DR: There can be widely differing proportionalities between BOLD and peak activity, and this is the likely reason for the low level of correspondence seen experimentally between ERP sources and BOLD measurements and that non-BOLD measurements, such as ERPs, can be used to correct for this effect to obtain improved activity estimates.
