A. Similar peaks in physiologic and physical spectra and cross-spectral coherence at other frequencies. Only a small circatrigintan difference is found between the time structure of Kp and a very premature boy's physiology (Figure 12/III). Spectra such as those of heart rate shown during the first 4 months of life and around 2 years of age, in parallel with the spectra of Kp, were computed. When the circatrigintan period of Kp is equated to 100%, the deviations in period of different physiologic variables of this boy are only of the order of 2%.

Cross-spectral coherence with Bz (the vertical component of the IMF induction vector) is found at a trial period of about 5 days (P=0.049) for this boy's systolic blood pressure and at a trial period near, yet different from, 3.5 days (P=0.008) for his diastolic blood pressure. Cross-spectral coherence between Kp and the blood pressure and heart rate of a clinically healthy cardiologist (YW) at high risk of developing cardiovascular disease is found at a trial period of 27.7 days (P<0.05) with a secondary peak at about 4 days (P<0.10). In the case of a woman (VLG) who spent over 3 months in isolation without time cues, cross-spectral coherence at a trial period of about 3.5 days is found between the disturbance of cosmic ray intensity (gauged by the standard deviation) and the micturition intervals and water excretion (P<0.01).

B. Cross-spectral coherence between the daily incidence of myocardial infarctions and Kp occurs at periods near, yet different from 7.0 and 3.5 days. This result suggests, as one of many possibilities, the influence of a variable sector structure of the IMF, consisting, e.g., of 3 spans of ~7.6 days and one of ~3.7 days during which the IMF is alternatively oriented toward or away from the sun. A strong coherence of myocardial infarctions with Bz and Kp is found at nearly identical periods. The adaptation of evolving life to such a sector structure may have contributed to the current endogenicity of the now primarily societally rather than sectorially synchronized circaseptan system, that prominently characterizes the incidence of emergencies (Figure 12/V, left).

C. Desynchronization (or rather free-run) of societally synchronized biologic rhythms from Kp and Bz. Morbidity/mortality statistics are 7-day synchronized, yet the phases of the near 168-hour component of the geomagnetic Kp index and of Bz are wobbly and drifting. That magnetic disturbance is at best an influencer is supported by the systolic blood pressure of a clinically healthy woman (Figure 12/V, right), which "free-runs" from a 164.4-hour component showing some stability for Bz.

D. Perturbations related to southward Bz turns. Southward turns of Bz have been associated with auroras and magnetic storms. A biologically relevant southward Bz turn was defined as a change between the daily average of Bz of >=1 nanoTesla (nT) to one of <=-1.5 nT. Once such an event is identified, the daily incidence of myocardial infarctions is recorded for these two days as well as for the two days preceding the day when Bz is >=1.0 nT (days -1 and -2) and the days following the day when Bz is <=-1.5 nT (days +1 and +2). The daily incidence of myocardial infarctions for these six days has been averaged over all events identified during this 3-year span. After a southward Bz turn, there is an increase in myocardial infarctions (P=0.027), Figure 12/II. During such an event, there is an increase in heart rate of a man (FH) who monitored this variable and blood pressure around the clock 6-10 years after a cardiac bypass operation. There may also be biologically effective events in the IMF that precede a southward Bz turn, since the blood pressure of FH is elevated before a southward Bz turn (P<0.05), Figure 12/II.

E. "Remove and replace" experiments. The circaseptan component of heart rate of a man (RBS) is less prominent during a span identified in Walsh spectra as lacking circaseptan features in solar activity.
