The problem of computing the closed loop transfer function of a linear system represented by its block diagram or by its flow graph is of importance in CAD programs designed for the analysis of linear ...

The new direct feedback loop, however, in response to the same range of incoming signal strength, was found to recruit strong inhibition in brain cells (neurons) in EC layers 2 and 3, never ...

This closed-loop negative feedback operation makes it difficult to identify open-loop dynamic characteristics of the neural and peripheral arcs. Regarding sympathetic AP controls, we examined the ...

The dual control of adiposity and longevity emerges from a latent intestinal feedback loop which simultaneously augments fat loss and shields lifespan from the deleterious effects of continuous fat ...

Like the Wright Brothers more than a century ago, the most effective loops will still be spurred by human ingenuity.
