Gaussian Process Regression (GPR)—The model response is calculated as a probability distribution function over the definition space. The GPR basis defines the exact form of a prior mean function. The kernel functions determine the input correlations in the output calculation as a function of distan...
and even lower, but also to unveil their localization in the time series from all birds. The successive branching of the period from these oscillatory rhythms exhibits a fractal pattern. Figure4depicts the amplitude of seven peaks
In the current study, we investigated the amplitude of low frequency fluctuations (ALFF) at rest and during a rumination induction. Specifically, we explored the differences of cortical blood oxygenation using fNIRS in subjects with Major Depressive Disorder (MDD) and healthy controls (HC). Ruminatio...
Dalrymple8 presented a finite amplitude wave in a constant shear flow using a numerical perturbation procedure, which led to a change in wavelength propagating over a vertically varying linear shear current; still, he mentioned the necessity of laboratory experiments to verify his results. Teles and...
However, the skill of even the latest models falls far short of the limit of potential predictability9,10,11. More importantly, the models fail to predict the observed event-to-event variability in evolution and amplitude of ENSO as highlighted by the failure of almost all models in predicting...
they have problems in a general definition of norm (in abstract algebra, a non-zero element a of a ring R is called a zero divisor if there exists a non-zero x such that ; for general properties of zero divisors see28). This was considered an obstacle for the use of these extended ...
The perception threshold of RVS following reduction of amplitude depth was assessed for each frequency individually using a staircase method (0.2 increments/decrements) for the definition of perceptual threshold. A repeated measures ANOVA with frequency (12, 14, 16, 18, 32, 34, 36, 38 Hz) as...
polynomial regressions of the characteristic curves offandg. This result allows us to obtain the system modeling and simulation based on the amplitude and phase Fourier spectrum obtained from the Fast Fourier Transform (FFT) of the sampledynversion ofy(t). It is shown that this technique has a...
Speckle, amplitude fluctuations in optical coherence tomography (OCT) images, contains information on sub-resolution structural properties of the imaged sample. Speckle statistics could therefore be utilized in the characterization of biological tissues.
TMG parameters definition. Full size image Dm (mm) is a parameter that reflects the maximal radial displacement of the muscle belly as a consequence of muscle contraction and depends on the flexibility and tone of the muscular tissue. Therefore, Dm values increase when the explosive force is dev...
