In the brain, it is thought that this current is responsible for attenuating back-propagating action potentials and excitatory post-synaptic potentials [ 3].
Interestingly, when pretreated with U0126, cell migration was attenuated back to basal levels in cells treated with HGF and expressing either control siRNA or ERK5 siRNA.
A Faraday's isolator (Newport) is placed at the laser output to attenuate back reflection of the pulse into the laser cavity due to fiber coupling.
This is not easy, and rarely 100% effective, but you can attenuate the backing tracks enough so that in context, the vocals sound like they're isolated.
While the n-back task increases working-memory effort parametrically, the decrease and increase of DMN activation seems to be attenuated from 1-back to 2-back.
In addition measurements in this band are somewhat ambiguous with respect to frequency because signal power above 100 Hz is not fully attenuated but aliased back into this band.
However, a single systemic administration of TNF antagonists in a clinical trial failed to attenuate leg and back pain associated with IVD herniation at three months or one year [ 36, 37].
A recent study by Victoria et al. (2010) searched for back-mutation of attenuating mutations in lots of eight live-attenuated virus vaccines strains, including OPV, using deep sequencing, and found none.
The reference arm contained absorptive neutral density (ND) filter in its focal plane to provide a weak reflection from its first surface while attenuating the reflection from the back surface.
However, many live-attenuated vaccines exhibit reversion to virulence through back-mutation of attenuating mutations, compensatory mutations elsewhere in the genome, recombination or reassortment, or changes in quasispecies diversity.
As the ultrashallow reflections may be contaminated with high-amplitude coherent noise in many aspects, first break muting and surgical muting were performed on each file as detailed as possible, and f k filtering was applied mainly for the purpose of attenuating the aliasing energy and back-scattered noise.
