4. Nonlinear dynamic models of the electrocardiograms(V.V. Pipin, Irkutsk)

The averaging procedure and extracting the typical ECG cycle

1. Constuct the ECG embedding into 3D phase space using the first 3 Principal Components of the ECG timeseries.

• 2. Divide ECG on the separate cycles using the maxima of QRS

• 3. Filtering the non-typical ECG beats out of the time- series via Housdorff distance

• 4. Averaging along the reference trajectory and researching of the dynamical characteristics

Model the ECG via parametric amplifier with an instant and dynamic quenching

It is appear, the additive external perturbations with lower frequency (in comparison with the internal

frequency) are more feasible than the higher frequency perturbations

One is responsible for the excitation and maintaining the cardiac oscillations. Another governs the maintaining the cardiac oscillations. Another governs the dissipation effects. The numerical solution shows the dissipation effects. The numerical solution shows the existence of the several dynamical regimes, including the existence of the several dynamical regimes, including the periodical, quasi-periodical and chaotic oscillations.periodical, quasi-periodical and chaotic oscillations.

- Human reaction on space weather changes is determined by not only upper-level organs and systems (for example, by nervous system), but mainly is realized at the lower, cellular level.

- The maximum of correlation is observed between different organism’s characteristics and cosmic rays intensity.

Response of a human organism at the cellular level

Hypothesis: Bio-effectiveness of cosmo-geophysical factors is an atavistic manifestation of the Earth biosphere’s adaptation

to much stronger cosmic rays intensity level during the terrestrial life forming epoch

The main causes of the “astrobiological mythology” appearance

Insufficient length of analyzed data rows ( the true dynamic structure loss).

Insufficient number of subjects ( individual peculiarities suppress characteristics, typical for the whole population).

Shortcomings of the initial experiment planning (useful signal intensity ≤ noise amplitude).

Generalization of the results obtained in one place to the whole population ( mishmash of local and global factors).

Future directions of the investigationFuture directions of the investigation

1. Global-scale approach: Creation of a telecommunication system for the test of Russian people’s health level as well as development of a new prognosis of bio-effective impacts of environmental factors.

2. Development of new models of space weather impacts on formation, migration and adaptation of different ethnosesin dependence on a geographical latitude of habitation.

3. Development of new nonlinear models of space weather impacts on humans.

4. Looking for new indices of space weather bio-effectiveness. 5. Development of new models of the Sun biosphereco-

evolution.6. Verification of the contemporal theories of the life’s origin.7. Verification and development of the solar dynamo models.
