COVID-19 cases, deaths may follow weekly pattern

MIT, Boston University, and Harvard Medical School researchers have identified weekly oscillations in the numbers of new daily COVID-19 cases and deaths in several countries that are more pronounced than fluctuations seen ...

Researchers use new method to investigate neural oscillations

Neural oscillations—also known as brainwaves—are important carriers of information in the brain. Researchers are increasingly coming to view them less as sustained oscillations and more as transient bursts. Until now, ...

Oscillation

Oscillation is the repetitive variation, typically in time, of some measure about a central value (often a point of equilibrium) or between two or more different states. Familiar examples include a swinging pendulum and AC power. The term vibration is sometimes used more narrowly to mean a mechanical oscillation but sometimes is used to be synonymous with "oscillation". Oscillations occur not only in physical systems but also in biological systems and in human society.
