Circadian Rhythms and Time-Dependent Biological Processes

In living systems, biological processes fluctuate over time due to the integration of internal and environmental factors. Among these, circadian (~24-hour) oscillations are particularly significant and widely studied in physiology. To analyze 24-hour patterns in time-series physiological data, the cosinor model is commonly used. However, many existing native applications for cosinor analysis are outdated, irregularly maintained, and often incompatible with modern operating systems.

To address this, we developed Cosinor.Online, a fully enthusiast-driven project designed for everyone, completely free of charge. The application runs in modern web browsers and is hosted on remote servers, ensuring 24/7 availability without the need for installation or software updates.
