Amplitude, phase, and period variations of the quasi 2‐day wave in the mesosphere and lower thermosphere over London, Canada (43°N, 81°W), during 1993 and 1994
TL;DR: In this article, the authors investigate the period, amplitude, phase, and vertical wavelength for the quasi 2-day wave in the mesosphere and lower thermosphere, using the University of Western Ontario 2 MHz radar near London, Canada, and in addition, they look at possible coupling with atmospheric tides.

A novel technique for markerless, self-sorted 4D-CBCT: feasibility study.
TL;DR: A novel technique employing the basics of Fourier transform theory was investigated for markerless extraction of respiratory phase directly from projection data and demonstrated to be feasible in achieving markerless, self-sorted 4D-CBCT reconstruction.

Phase Derivatives and Simulation of Strong Ground Motions
TL;DR: In this article, the authors proposed an extension of the standard stochastic method to produce nonstationary frequency content, as pro-duced by ground motions containing surface waves.
