Many designs exist for logic-based astable multivibrators, one of the simplest being an RC feedback loop around a single inverting Schmitt ... These uncertainties make it difficult to design the ...

This back-up circuit ensures that increased concentrations ... The end result is a positive feedback loop which drives the continuous accumulation of both SIRT1 and c-MYC in the cell.

Switching power supplies rely on feedback control loops to ensure ... which contributes to the slowness of the loop. Ideally, a positive loop gain at 1 or 2 kHz is desirable, and given the ...

This process forms a positive glutamate-NO-glutamate feedback loop. Their study, published in iScience, indicates that the ...
