The phrase "a positive feedback of" is not correct in standard written English.
The correct expression is "positive feedback on" or "positive feedback about."
Example: "The team received positive feedback on their recent project presentation."
Alternatives: "favorable response to" or "constructive comments regarding."
In order to prevent this deterioration, a stiffness control achieved by a positive feedback of the displacement signal of the rubber spring is proposed and the effectiveness of the stiffness control is confirmed by simulations and experiments.
Results show a positive feedback of children and teachers about the use of tactile digital devices, and a significant improvement of the performances of the multi-criteria architecture compared to the previous analyser.
The increase in renal angiotensinogen mRNA level observed in HFv rats was markedly attenuated in enalapril treated HF rats (P < 0.001), suggesting a positive feedback of angiotensin II on renal angiotensinogen synthesis.
These BMPs also regulate the expression of BMP2 and BMPR2 genes, suggesting the possibility of a positive feedback of stimulation of BMP-2 signaling pathway.
Alternatively, these GmGT-2B-upregulated genes may reflect a positive feedback of the ABA response due to the reduction of ABA sensitivity.
In this study we report on a positive feedback of IL-23 production, but negative feedback mechanisms may exist as well.
Both HPV16 E2 and E6 act as RNA-binding proteins and suppress splicing of the HPV16 E6 intron, suggesting the presence of a positive feedback loop of E6 production.
PI 4,5 P2 concentrations were high in ruffles but increased after ruffle closure, suggestive of a positive feedback amplification of PI4P5K in cups.
Moreover, nitric oxide increased endogenous levels of GRHL3, suggesting a positive feedback loop of nitric oxide on GRHL3.
These data are in agreement with the known regulation of Lef1 by a positive feedback loop of Wnt signaling [ 42, 43].
We propose the scenario in which miR-155 targets PKIα to prevent the inhibition of PKA, thereby maintaining a positive feedback loop of its own expression.
