Scientists find a 'dangerous feedback loop' in sudden sea ice melt Over the past few years, researchers have discovered dramatic and "unexpected" shifts in the Southern Ocean, with saltiness ...

What can the systems theory distinction between positive and negative feedback tell us about how recovery succeeds?

Blood glucose levels of vitamin D-calcium deficiency rats decreased significantly (p < 0.05) by 39.87 mg/dL. Vitamin D3 encapsulated liprotide improves vitamin D and calcium in the blood more ...

We wanted to know if giving women calcium as a supplement before pregnancy or during early pregnancy would help pregnant women avoid pre-eclampsia, high blood pressure, and other serious health ...

Researchers at the University Medical Center Göttingen (UMG) have shown how a minimal change in a single ion channel increases the sensitivity of sensory cells in the inner ear. Even soft sounds ...

For each, we describe the relevant feedback mechanisms, examples, and policy implications. Decision makers that understand and harness these dynamics will be at an advantage in accelerating clean ...

In this brief, an output feedback continuous twisting algorithm is applied to solve the problem of glucose regulation in critically ill patients affected with type 1 diabetes mellitus. The proposed ...
