Many physiological behaviours of cells are repeated periodically in time, such as hormone secretion, second messenger signalling, cell-division cycles and circadian rhythms. Oscillatory behaviour is a ...

The epidermal growth factor receptor (EGFR)/ERBB family has evolved from a primordial, simple pathway of a single ligand receptor pair to a complex signalling network. Studies in invertebrates and in ...

The most important design parameters in dc/dc power conversion design are the calculations and methodologies involved in feedback loop compensation. When these parameters are not properly calculated, ...

When sea ice melts, it can lead to faster warming because water absorbs more heat than ice does. That’s one of more than 25 climate feedback loops found in a recent study from Oregon State University.

Spoiler alert: There isn’t one. Closing the feedback loop is notoriously challenging. To correct and adapt our programming, we need to understand what doesn’t work, who it doesn’t work for, and what ...
