A parametric spectral model using acquisition specific, a priori information is combined with a wavelet-based, nonparametric characterization of baseline signals.
Preoperatively, a scanner and acquisition specific template created from 30 healthy control subjects, 15 patients with left and 15 patients with right hippocampal sclerosis was used for normalization.
where s0 is the baseline signal which is obtained without applying any gradients, b is an acquisition-specific constant known as b-value (which is a measurement of the strength of the diffusion weighting), w j are convex weights, and D j is a tensor matrix characterizing the diffusion pattern.
Images were realigned for movement correction, normalized to an acquisition-specific echo planar imaging template in Montreal Neurological Institute space, resampled to isotropic 3 × 3 × 3 mm voxels and smoothed with an 8 × 8 × 8 mm kernel.

Thus, CGTases most likely evolved from a common ancestor to diversify in product specificity by acquisition of specific mutations at the substrate binding sites.
Acquisition of specific groups of genes conferred specialized functions to specific strains, but their core genomes were identical.
As a defense mechanism, they offer an opportunity to generate virus-resistant strains or even to construct strains refractory to the acquisition of specific genes.
Conditional associative sensori-motor learning (i.e. the acquisition of specific arbitrary sensori-motor mappings) involves several processes that depend upon the integrity of the fronto-striatal system.
In multicellular organisms, signal transduction is essential to these processes, yet while our understanding of how signals regulate gene expression is relatively advanced, our understanding of how signals direct the acquisition of specific shapes and forms is less advanced.
