A clear enhancement of the feedback effects is proven.
When the metamaterial resonance matches the QD absorption peak, we obtain a clear enhancement of generated photocurrent.
These results are corroborated by fluorescence spectroscopy measurements, which show that specific drug/GAG complex formation is accompanied by a clear enhancement of the fluorescence intensity.
Other parameters, like air changes per hour or the use of permeable coverings, present a clear enhancement of indoor environment conditions.
At 1000 1030 UT, a clear enhancement of the power spectral density (PSD) was observed at MGD, PTK, and MSR at a frequency range of 0.1 2 Hz.
This led to a clear enhancement of local tissue perfusion decreasing the ischemic area in a skin flap model in rats [205].
The treatment based on dissolution/precipitation in ionic liquids yields a clear enhancement in the conversion of cellulose and glucose formation with heterogeneous catalysts.
Post irradiation, during recovery, a clear enhancement in the content of the 2-Cys-Prx protein was observed.
There was a clear enhancement in the amount of bound VCP in cells infected with wild-type S. Typhimurium, whereas this increase was not evident when cells were infected with the ΔsptP null mutant.
There was a clear enhancement in the enantiomer selectivity of the biotransformation of the diol when vinyl butanoate is used as the acyl donor.
There is a clear enhancement in the nucleoplasmic accumulation of RPL27-GFP, when inhibition of the proteasome with MG132 is preceded by blocking rRNA transcription with actinomycin D. By contrast, both nucleolar and cytoplasmic RPL27-GFP levels showed little or no change when the cells were treated with actinomycin D before MG132 treatment.
