This phase-preference precisely matches the ability of CA1 place cells to fire with highest frequency on the trough of theta in the range 180 270° (O∼Keefe & Recce, 1993; Mehta et al., 2002).
The strong coupling occurs at the trough frequencies where the membrane interacts actively with the cavity and the exterior field.
Longitudinal changes in diurnal variations of F2-layer critical frequencies, of the trough's parameters, and probabilities of ionospheric disturbances of different kinds are discussed.
Results show that the natural frequencies of the trough solar collector are closely spaced, and the inherent dynamic characteristics measured under various pitch angle coincide with the results of the finite element simulations.
To maintain oscillation frequency stable, IPSC troughs should be negatively correlated to the input, i.e. larger negative currents for stronger external excitation.
In contrast to Beeler and Lockner (2003), who reported that diurnal tides cannot trigger earthquakes based on data from laboratory experiments, tremors were found to show tidal sensitivities at such high frequencies in the Nankai Trough (Yabe et al. 2014), which can indirectly trigger earthquakes.
Pharmacokinetic evaluation of both synovial fluid and serum in this study suggested that adequate IL-1 inhibition should have been achieved with the dose and frequency of AMG 108 administered (trough concentrations exceeded the IC90 value for IL-1β-induced IL-6 inhibition at trough levels in both serum and synovial fluid).
Red dots indicate the epicenters of low-frequency earthquakes along the Nankai Trough from January 2006 to December 2010.
Low-frequency tremors along the Nankai Trough are distributed in a belt-like zone at depths of about 30 km on the plate interface, and a distinct gap occurs in the Kii Channel (Obara 2009).
Hirose et al. (2010) discussed slow earthquakes including ETS events, long-term SSEs, and shallow very-low-frequency earthquakes in the Nankai Trough and highlighted the importance of monitoring slow earthquakes as proxies for the stress modulation process.
A recurring problem with early phonograph designs was that mechanical resonances in the pickup and sound transmission mechanism caused excessively large peaks and troughs in the frequency response, resulting in poor sound quality.
