Area of Science:

  • Mathematical Biology
  • Signal Processing
  • Physiological Monitoring

Background:

  • Biological systems generate complex event streams.
  • Traditional analysis methods may not fully capture dynamic physiological rhythms.
  • Understanding these rhythms is crucial for diagnostics and therapeutics.

Purpose of the Study:

  • To present an original mathematical approach for Fourier analysis of biological event streams.
  • To demonstrate the isolation and display of phase and amplitude dynamics of biological rhythms.
  • To provide a foundation for modeling biological systems and monitoring drug influences.

Main Methods:

  • Developed a novel mathematical framework for Fourier (spectrum) analysis.
  • Applied the method to analyze event streams characterizing biological systems.

    • Successfully isolated and displayed the dynamics of diapasons (frequency bands) in biological data.
    • Illustrated the method with examples like Traube-Hering and Mayer waves during functional testing.
    • Demonstrated the potential for detailed characterization of physiological rhythms.

    Conclusions:

    • The proposed Fourier analysis approach offers a powerful tool for studying biological system dynamics.
    • This method facilitates the construction of structural-functional numerical models of biological systems.
    • It serves as a basis for monitoring and measuring the effects of pharmacological interventions.
