The concurrence of major oscillation processes and the maximum power of the 3 7 year band fluctuation defined a period of intense hydrological activity from approximately 1998 2002.
This occurs because the X-band fluctuations underlie two-way propagation conditions while the S-band fluctuations are essentially the product of a one-way propagation experiment.
The wide channel band experiences fluctuations across the different frequencies, causing diversity in the frequency domain.
A novel feature of the present study is the presence of high levels of broad band freestream fluctuations.
In this frequency range, the spectral ratios tend to have smaller fall-off rates than in the lower frequency band, but fluctuations of the ratios are too large to be examined for frequency dependence of Q.
A cross-correlation analysis between S- and X-band amplitude fluctuations shows that the fluctuation signature at S-band appears to be shifted to earlier times with respect to the X-band recording.
The electric resting state network (eRSN) analysis will follow a multi-step procedure comprising i) pre-processing of EEG signals, ii) extracting band amplitude fluctuation envelopes at the frequency band of interest, and iii) evaluating their network characteristics within two modes of activity.
An absence of change in the Stokes-like shift due to reduction of TD density revealed that the effective band-gap fluctuation in InGaN QWs was not due to a phase separation initiated by TDs (60, 61).
The observational data analyzed in the present work are S-band frequency fluctuation measurements recorded during the solar conjunctions at different phases of solar activity cycle #23, specifically: periods near solar maximum (three conjunctions), near solar minimum (three conjunctions) and during the ascending phase (one conjunction).
We focus here on the spontaneous neuronal dynamics in the infra-slow frequency band, infra-slow fluctuations (ISFs), and explore their electrophysiological substrates and behavioral correlates.
For salinity a different strategy was applied where a moving average procedure was carried out, as the data did not suffer from spikes and exhibited almost a constant band of noisy fluctuations.
