Abstract The sawtooth-patterned glacial-interglacial cycles in the Earth’s atmospheric temperature are a well-known, though poorly understood phenomenon. Pinpointing relevant mechanisms behind these will not only provide insights into past climate dynamics, but also help predict possible future responses of Earth system to changing CO $$_2$$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/Math...

The circadian system of Neurospora crassa includes a molecular feedback loop that is entrainable by light. A recent study has shown that a second, elusive oscillator interacts with the feedback loop to drive output rhythms.

Flow theory suggests three flow conditions lead to flow: optimal challenges, clear goals, and immediate feedback. Previous research has only confirmed the link between challenges with controlled experiments. Inspired by Miller’s test-operate-test-exit (TOTE) units Csikszentmihalyi’s theory, we introduce a feedback loop of model cognitive processes that in computer-based tasks. This illustrates ...
