Detection of respiratory frequency rhythm in human alpha phase shifts: topographic distributions in wake and drowsy states by Aleksandar Kalauzi, Zoran Matić, Edin Suljovrujić, Tijana Bojić

“…Since our approach allows for a more precise calculation of CF phase shifts (CFPS) than any individual Fourier component, by using a 2-s moving Fourier window, we validated the new method and studied, for the first time, temporal waveforms CFPS(t) and their oscillatory content through FFT (CFPS(t)).ResultsAlthough not appearing equally in all channel pairs and every subject, a clear peak in the respiratory frequency region, 0.21–0.26 Hz, was observed (max at 0.22 Hz). …”

Conceptual foundations of a REFRAME-based approach to discriminate across total knee implant designs based on the positions of functional centres of rotation by Adrian Sauer, Ariana Ortigas-Vásquez, Christoph Thorwaechter, Peter E. Müller, Henning Windhagen, Allan Maas, Thomas M. Grupp, William R. Taylor, Matthias Woiczinski

“…The kinematic signals of these five configurations were compared to determine whether key differences between implants could be detected leveraging two methodological approaches: (1) statistical parametric mapping to directly compare waveforms and (2) simple paired t-tests to compare the three-dimensional coordinates of the functional centres of rotation determined using a previously published REference FRame Alignment Method (REFRAME). …”
