It is this relationship between field strength and frequency implemented onto the hydrogen atoms within the tissue that allows the use of nuclear magnetic resonance for imaging.
Experimental results obtained with a low-pass filter with tunable cutoff frequency implemented in a 0.35 μm CMOS process to verify the effectiveness of the design procedure have shown close agreement with the theory.
Application of LFS (600 pulses) at a range of frequencies revealed that the successful induction of FF in vivo is tightly dependent on the LFS frequency implemented (Fig. 2).
We conducted a Principal Coordinate Analysis (using NTSYS) based on NST indices, and an AMOVA of haplotype frequencies, implemented in Arlequin, to assess the proportion of genetic variance found at the region (North America vs. Europe), population and individual levels.
We obtained Wright's F-statistics, F IT, F ST, and F IS [ 34] from the analysis of variance of allele frequencies, implemented in the software FSTAT 2.9.3.2 [ 35].
Finally, factorial correspondence analysis (FCA) based on allele frequencies implemented in GENETIX was used to illustrate the two-dimensional spatial representation of genetic differentiation among populations over multiple years.
The χ2 tests for deviation of amino acid frequencies implemented in TREE-PUZZLE, version 4.02 [ 23], were applied to the datasets and sequences that failed the test were excluded from further phylogenetic analysis since the currently available phylogenetic methods cannot deal with strong amino acid compositional heterogeneity in the data [ 24].
The first model included, in addition to the school-aggregated student background variables, the school-aggregated students' perceptions of the frequency of implementing one specific instructional mode.
The association between the frequency of implementing an instructional mode and the average achievement score of schools in each group of countries can be visualized by plotting a line on a graph between the predicted schools' mean score in mathematics or science at two distal frequencies of implementing the instructional mode.
The system uses AOM frequency shifters implementing a multiple delay element with P delays in the reference arm, each traversed by a deflected beam at a different angle and with a different frequency shift as imprinted by the AOMs.
