Despite their high level of attenuation in monkeys, the chimeras induced a moderate-to-high titer of neutralizing antibodies and prevented viremia in monkeys challenged with WN.
In the proposed structure a novel harmonic suppressed Wilkinson power divider used in DPA, which results in harmonic suppression with high level of attenuation.
Moreover, when compared with a commercial live vaccine strain, SC-54, the two mutants showed a higher level of attenuation in mice and ΔphoP also in pigs.
However, the processing efficiency and throughput with a single beam can be insufficient because of the high level of attenuation needed for the output to meet the required 'thermal-free' parameters.
The high level of attenuation of Kim53ΔnlpD motivated us to evaluate the potential of this defined mutant to serve as a vaccine.
The high level of attenuation of this vector is illustrated by its failure to spread in immunodeficient mice, its dramatically reduced ability to replicate in a variety of human cells in tissue culture, and its inability to produce infectious virus in human beings [22].
The main drawback of optical imaging techniques are the high level of attenuation of signal with depth and the background signal due to autofluorescence, calling for new fluorophores to improve in vivo imaging [ 4, 9].
The cancellation of local volume velocity by using small acoustic sources placed on or close to the vibrating surface is also considered and is shown to achieve even higher levels of attenuation in the radiated sound power than for tiles which cover the entire surface.
Previous educational attainment is measured at a time-point prior to initiation of these substances; high levels of attenuation within this covariate model would indicate a problem with reverse causation.
The effective atomic number provides a higher level of discrimination than attenuation in HU because it depicts the material make-up of each pixel [4, 5].
