An important limitation of NMES is the limited spatial recruitment of muscle fibres [ 20].
As a result, it is likely that the dissection of haplogroups C and D into subhaplogroups of younger age and more limited geographic and ethnic distributions might reveal previously unidentified spatial frequency patterns, which in turn could be correlated to prehistoric and historical migratory events.
Thus, due to the multiple illumination beam superposition at the sample, each raw image Y k contains multiplexed regions of spatial frequency content that are individually diffraction-limited and have identical frequency support, but are shifted over different regions of the sample spectrum.
Methods that have been previously adopted such as EEG, single neuron recording, local field potentials, and functional magnetic resonance imaging (fMRI) have either limited spatial or temporal resolution or are unable to provide frequency-specific information or to yield dynamic spatiotemporal profiles of cognitive processing.
First, because the wavefront error is sampled with a limited number of lenslets, there could potentially be undetected high spatial frequency features in the wavefront.
However, due to the limited spectral bandwidth of the light source, only a limited range of the spatial frequencies from the scattering object are captured, as visualized through the windowing function in Fig. 2(i).
According to this view, perception is based on a population of units, each tuned to a limited range of values for a stimulus property (e.g., orientation, direction of motion, spatial frequency).
Thus, spatial frequency variations above 3.12 cycles/cm are not meaningful due to the limited resolution of the FEM model.
The spatial frequency is the reciprocal of the period.
In contrast to well-sorted conglomerates, formations are usually thick and of limited spatial distribution.
As an example, spatial frequency components having a period of 1 μm would have a spatial frequency of 1,000 lines per millimetre.
