For the first two, more heavily contaminated segments, the agency plans to dredge or "stabilize" the sediment in some areas by mixing it with concrete or a similar material and then capping it with layers of clay, sand and gravel.
Therefore, we visually inspected all data for segments the containing artifacts from head movement or environmental noise and discarded contaminated segments.
Muscle artefacts were separated from a contaminated segment of background activity using BSS-CCA [7].
Movement artefacts were corrected by an established procedure (Koch et al. 2006; Wartenburger et al. 2007), which allows marking of artefacts and then padding the contaminated data segments by linear interpolation.
After removing the time segments contaminated by instrumental or artificial noise and excluding the unreliable phase velocity data, the final time segments used in Fig. 5 are 380, 377, 179 and 99 for the S-, M-, L- and X-arrays, respectively.
EEG segments contaminated by amplifier clipping, bursts of electromyographic activity, or peak-to-peak deflection exceeding ± 100 μV were excluded from the average calculation.
Recording segments contaminated by signal saturation or loss of fixation were discarded and repeated.
EEG segments contaminated by physical (eye blinks, eye movement, head movement, sucking, or excessive muscle activity) and electronic artifacts were rejected by visual assessment.
While magnetocardiogram (MCG) artifacts were corrected by using the cardiac remover (part of the Whole Head System software, version 1.2.5; 4D Neuroimaging), time segments contaminated by EOG artifacts were excluded from further analysis.
The insert DNA segment free of contaminating vector sequences can be used as a hybridization probe and for insertion into a new vector since suitable cohesive termini are generated from the retained poly dA) and poly dT) tails by an appropriate exonuclease.
The EEG segment contaminated by amplifier clipping, bursts of electromyographic activity, or peak-to-peak deflection exceeding ±100 μV were excluded from averaging.
