It was established that it bears a discrete nature and that in it may be contained eight frequencies of a nonreinforced shell. It was shown, how elastic and geometric characteristics of the stringer, as well as its disposition, on the shell, affect the magnitude of eight frequencies of a ...
An extended nonlinear recharge oscillator model shows skilful and explainable El Niño–Southern Oscillation forecasts at lead times up to 16–18 months, better than global climate models and comparable to the most skilful artificial intelligence forecasts. ...
However, these oscillations also tend to be continuous in nature although low in amplitude. The four lowest frequency oscillations have periods of approximately 55, 36, 27, and 22 min. The 55-min period corresponds to the first longitudinal mode of oscillation, and the 36-min period, to the...
The hole-spin coherence was found to be limited by a 1/f0.5 charge noise at high frequencies (104−106 Hz), with a strong dependence on the magnetic-field orientation that could be faithfully accounted for by the spin-electric susceptibilities. A largely enhanced spin coherence was ...
The window aims the minimization of leakage, an error expressed by the spreading of the true spectrum components along other neighbouring frequencies and motivated by the finite nature of the time segments [3]. Since the window reduces the contribution of the data at the beginning and end of ea...

(mDFPS) of lower than 50% is consequently a major public health issue, especially taking into consideration the global target geared towards achieving an mDFPS of at least 75% by year 2030 for all countries. In view of this, together with recognising the feasible contextual nature of wellness...
On-line comprehension of natural speech requires segmenting the acoustic stream into discrete linguistic elements. This process is argued to rely on theta-gamma oscillation coupling, which can parse syllables and encode them in decipherable neural activi
