  We have demonstrated the existence of a pyramid power and have revealed its characteristics by strictly scientific experiments using biosensors. We also revealed the existence of a Bio-Entanglement, an entangled relationship between biosensors. A parallel study of biosensors (edible cucumber slices) had also been conducted, and we found that the circadian rhythm of gas concentrations emitted from biosensors changes seasonally. The pyramid power and Bio-Entanglement did not change the number of cycles in the periodic approximation curve representing circadian rhythm. Therefore, in this paper we analyzed the influence of the pyramid power and Bio-Entanglement, 
  <em>i.e.</em>, their influence on the phase, amplitude, and correlation coefficient of the periodic approximation curve representing the circadian rhythm of emitted gas concentrations. The main results are as follows. 1) The pyramid power shifted the phase of the periodic approximation curve representing the circadian rhythm by 43 minutes. 2) The amplitude of the periodic approximation curve changed with the pyramid power and the Bio-Entanglement. The effect on the lower and upper sections of the biosensors stacked in two layers was different, with a tendency to increase the amplitude of the lower layer and decrease the amplitude of the upper layer. 3) The pyramid power and the Bio-Entanglement affected the correlation coefficient between gas concentration and the periodic approximation curve representing the circadian rhythm of gas concentration. The effect on the lower and upper layers of the biosensors was different, with a tendency for the lower layer correlation coefficient to be larger and the upper layer correlation coefficient to be smaller. Previously we demonstrated that the pyramid power and the Bio-Entanglement affect the ratio of gas concentration, 
  <em>i.e.</em>, psi index 
  <em>Ψ</em>. In this paper we demonstrate for the first time that the pyramid power and the Bio-Entanglement affect time, 
  <em>i.e.</em>, phase difference.

INTRODUCTION</title><p>Vegetables and fruits are known to have long-lasting biological reactions even after harvesting. And when the plants are subjected to some stimulation or injury after harvest, they may release various types of volatile components. Plants use these volatile components for communication with other plants, defense against foreign enemies, and immune actions [1 - 10].</p><p>As biosensors we have been using cucumber sections, Cucumis sativus, which release volatile components. By measuring and analyzing the concentrations of gas emitted from the biosensors, we have revealed unexplained phenomena that could not have previously been captured by regular electrical instruments [11 , 12].</p><p>Unexplained functions, a pyramid power which a pyramidal structure (PS) is said to have are of great scientific interest. Since October 2007, we have been conducting rigorous scientific experiments using the biosensors on a pyramid in which a test subject can enter and meditate in order to elucidate the unexplained power of the pyramidal structure, the pyramid power (<xref ref-type="fig" rid="fig1">Figure 1</xref>). In parallel, we are also studying the characteristics of the biosensors. We have demonstrated the existence of the pyramid power and have revealed its characteristics. Our studies also revealed the existence of a circadian rhythm in which the gas concentrations emitted from the biosensors varies with the seasons. As a result of our research to date, we have published 10 original papers demonstrating the pyramid effect [13 - 22], 3 original papers characterizing cucumbers used as the biosensors [23 - 25], 3 comprehensive reports [26 - 28], and 1 book [<xref ref-type="bibr" rid="scirp.122792-ref29">29</xref>]. Analysis of the pyramid effect on the biosensors revealed the existence of a phenomenon similar to quantum entanglement between cucumber sections due to pyramid power, which we named Bio-Entanglement [20 - 22].</p><p>In a previous paper, we reported that the circadian rhythm of gas concentrations emitted from biosensors changes seasonally, i.e., the circadian cycle is 8 hours in winter, 6 hours in spring, 24 hours in summer, and a mixed cycle of 12 and 24 hours in autumn [<xref ref-type="bibr" rid="scirp.122792-ref25">25</xref>]. In the experiment, eight biosensors G<sub>E1</sub>, G<sub>E2</sub>, G<sub>E3</sub>, G<sub>E4</sub>, G<sub>C1</sub>, G<sub>C2</sub>, G<sub>C3</sub>, G<sub>C4</sub> were placed as shown in <xref ref-type="fig" rid="fig1">Figure 1</xref>(c). We found that all eight gas concentrations had different circadian rhythms at different seasons: G<sub>E1</sub> and G<sub>E2</sub> were affected by the pyramid power, G<sub>C1</sub> and G<sub>C2</sub> were affected by the Bio-Entanglement, and G<sub>E3</sub>, G<sub>E4</sub>, G<sub>C3</sub> and G<sub>C4</sub> of the control placed at the calibration control point, oscillated in the same way. Thus, at the time the paper was published [<xref ref-type="bibr" rid="scirp.122792-ref25">25</xref>], we had found that the pyramid power and the Bio-Entanglement had no effect on the number of cycles of the circadian rhythm of gas concentration.</p><p>The purpose of this paper is to analyze whether or not there are any effects on anything other than the number of cycles. Specifically, the phase and amplitude of the periodic approximation curve representing the circadian rhythm of the gas concentration emitted from the biosensors and the correlation coefficient between the gas concentration and its periodic approximation curve are studied in detail, and the influences of the pyramid power and the Bio-Entanglement on the phase, amplitude and correlation coefficient are analyzed.</p></sec><sec id="s2"><title>2. PREPARATION, INSTALLATION AND STORAGE OF THE BIOSENSORS, AND GAS CONCENTRATION MEASUREMENT OF THE BIOSENSORS</title><p>In one set of pyramid power detection experiments, eight uniform biosensors G<sub>E1</sub>, G<sub>E2</sub>, G<sub>E3</sub>, G<sub>E4</sub>, G<sub>C1</sub>, G<sub>C2</sub>, G<sub>C3</sub>, G<sub>C4</sub> were prepared from four commercial edible cucumbers (<xref ref-type="fig" rid="fig1">Figure 1</xref>(a) and <xref ref-type="fig" rid="fig1">Figure 1</xref>(b)). To prepare eight uniform biosensors, each Petri dish contains four cucumber sections, one from each of the four cucumbers. In pairs 1 to 4 shown in <xref ref-type="fig" rid="fig1">Figure 1</xref>(b), the surfaces of the cucumber sections for each pair are identical cut surfaces. However, only the direction of the cut surface is different. That is, G<sub>E1</sub>, G<sub>E2</sub>, G<sub>E3</sub>, and G<sub>E4</sub> are experimental samples and the direction of the cut surface is the same as the growth axis, while G<sub>C1</sub>, G<sub>C2</sub>, G<sub>C3</sub>, and G<sub>C4</sub> are control samples and the direction of the cut surface is opposite to the growth axis (<xref ref-type="fig" rid="fig1">Figure 1</xref>(a), lower panel). G<sub>E1</sub>, G<sub>E2</sub>, G<sub>E3</sub>, G<sub>E4</sub>, G<sub>C1</sub>, G<sub>C2</sub>, G<sub>C3</sub>, and G<sub>C4</sub> represent the Petri dishes of the eight biosensors, as well as the gas concentrations (ppm) released from the biosensors in each Petri dish.</p><p>The reason for using eight uniform biosensors in one set of experiments was to utilize the Simultaneous Calibration Technique (SCAT) devised at the International Research Institute (IRI) in experiments to detect healing and pyramid power effects [<xref ref-type="bibr" rid="scirp.122792-ref30">30</xref>]. SCAT is a sensing method that reveals spatial characteristics using biosensors, which are considered environmentally responsive, highly sensitive sensors. This method eliminates data bias due to individual differences in cucumbers and changes in environmental conditions. This made it possible to detect weak effects affecting the cucumber gas production reaction that would otherwise be buried as noise. And we have been able to detect human healing capacity [11 , 12] and pyramid power [13 - 29], which were difficult to detect by regular electrical instruments.</p><p>In the experiment, G<sub>E1</sub> and G<sub>E2</sub> were placed at the PS apex in two layers. G<sub>C1</sub>, G<sub>C2</sub>, G<sub>E3</sub>, G<sub>E4</sub>, G<sub>C3</sub>, and G<sub>C4</sub> were placed at the calibration control point 8 m away from the PS apex in two layers (<xref ref-type="fig" rid="fig1">Figure 1</xref>(c)). The biosensors G<sub>E3</sub>, G<sub>E4</sub>, G<sub>C3</sub>, and G<sub>C4</sub> of pairs 3 and 4 were under the same environment from preparation to installation at the calibration control point and storage after installation. Therefore, the four biosensors were assumed to have the same biological response to produce the gas and could serve as controls. The biosensors were placed at the PS apex and the calibration control point simultaneously for 30 min, then the Petri dish lids were removed, and the dishes with the biosensors were placed in a sealed polypropylene container with a volume of 2.2 liters, and stored in a temperature-controlled (22 - 24 degrees Celsius) room with no direct sunlight for 24 h - 48 h. During storage, the gas concentration in the sealed container has been found to reach a maximum in about 12 hours and then remain in equilibrium [<xref ref-type="bibr" rid="scirp.122792-ref31">31</xref>]. Gas concentration was measured by aspirating 300 ml of gas in a sealed container using a gas detector (GV-100: GASTEC, Japan) and a gas detector tube (141 L: GASTEC).</p><p>It has been reported that there are 16 main gas components released from cucumber sections, and we understand that we are measuring the concentration of 2-hexanol among them [32 , 33]. The reason for this is that the gas detector tube 141 L is originally intended for ethyl acetate detection, but 2-hexanol is detectable. However, when identifying the absolute value of the 2-hexanol gas concentration, it was necessary to multiply the detector tube reading (ppm) by three from the conversion factor. The 16 mixtures of gases released from cucumbers include isomers of 2-hexanol and other compounds. Therefore, to obtain an accurate value for the gas concentration, the composition ratio of the 2-hexanol isomer and the conversion factor are needed, but these are not known at this time. However, the purpose of this paper is not to determine the absolute value of gas concentrations emitted from cucumber sections, but to determine the effects of the pyramid power and the Bio-Entanglement on the periodic approximation curve representing the circadian rhythm of gas concentrations. Therefore, we used the detector tube reading (ppm) as the gas concentration in our analysis.</p></sec><sec id="s3"><title>3. PERIODIC APPROXIMATION CURVE OF GAS CONCENTRATION</title><p>To clarify the circadian rhythm of gas concentration, we first obtained a periodic approximation curve of gas concentration that repeats the same phase every 24 hours. The correlation between gas concentration and the periodic approximation curve was then analyzed, and the correlation coefficient and its significance were examined to determine if a circadian rhythm existed in gas concentration.</p><p>We used Equation (1) as the periodic approximation curve.</p><p>y = a + b sin ( 2 π x N ) + c cos ( 2 π x N ) = a + b 2 + c 2 sin ( 2 π x N + φ ) ,       φ = arcsin ( c b 2 + c 2 ) (1)</p><p>Here, a, b, and c are constants, and π is the circumference ratio. The variable x represents the time, and it is a value corresponding to the time from 0:00 to 24:00 with a numerical value from 0 to 1. If the post-harvest cucumbers maintained a circadian rhythm, the gas concentrations released by the biological response were also assumed to follow a circadian rhythm that was in phase every 24 hours. N is the number of cycles per 24 hours and here we consider N to be an integer from 1 to 24. Equation (1) therefore represents the period approximation curve with one period of 24 hours for N = 1 and one period of 1 hour for N = 24. We determined the periodic approximation curves for each of the eight gas concentrations G<sub>E1</sub>, G<sub>E2</sub>, G<sub>E3</sub>, G<sub>E4</sub>, G<sub>C1</sub>, G<sub>C2</sub>, G<sub>C3</sub>, and G<sub>C4</sub> for N ranging from 1 to 24 and determined the constants a, b, and c. The correlation coefficient between the gas concentration and the periodic approximation curve was then calculated. If the correlation coefficient was significant, we considered the period of the periodic approximation curve to be the period of the circadian rhythm of the gas concentration.</p></sec><sec id="s4"><title>4. CIRCADIAN RHYTHM OF GAS CONCENTRATION</title><p>The data used in this paper to analyze the circadian rhythm of gas concentrations were the same data used in the six-paper series “Potential Power of the Pyramidal Structures I-VI” [17 - 22] and in the previously published paper [<xref ref-type="bibr" rid="scirp.122792-ref25">25</xref>].

In this paper, we analyzed the circadian rhythm of the gas concentration of each of the eight biosensors, always recognizing the differences between how the pyramid power affected biosensors G<sub>E1</sub> and G<sub>E2</sub>, the Bio-Entanglement affected biosensors G<sub>C1</sub> and G<sub>C2</sub>, and the control biosensors G<sub>E3</sub>, G<sub>E4</sub>, G<sub>C3</sub>, and G<sub>C4</sub>, as well as between the two stacked lower and upper layers of biosensors in the experiment.</p><table-wrap id="table1" ><label><xref ref-type="table" rid="table1">Table 1</xref></label><caption><title> Classification of the four seasons and their duration, as well as the number of data for each season</title></caption><table><tbody><thead><tr><th align="center" valign="middle" >Classification</th><th align="center" valign="middle" >Season</th><th align="center" valign="middle"  colspan="2"  >Period</th><th align="center" valign="middle" >Number of data</th></tr></thead><tr><td align="center" valign="middle" >WTR</td><td align="center" valign="middle" >winter</td><td align="center" valign="middle" >from the winter solstice to the day before the spring equinox</td><td align="center" valign="middle" >from 12/22 to 3/20</td><td align="center" valign="middle" >84</td></tr><tr><td align="center" valign="middle" >SPR</td><td align="center" valign="middle" >spring</td><td align="center" valign="middle" >from the spring equinox to the day before the summer solstice</td><td align="center" valign="middle" >from 3/21 to 6/20</td><td align="center" valign="middle" >108</td></tr><tr><td align="center" valign="middle" >SMR</td><td align="center" valign="middle" >summer</td><td align="center" valign="middle" >from the summer solstice to the day before the autumn equinox</td><td align="center" valign="middle" >from 6/21 to 9/22</td><td align="center" valign="middle" >144</td></tr><tr><td align="center" valign="middle" >AUT</td><td align="center" valign="middle" >autumn</td><td align="center" valign="middle" >from the autumn equinox to the day before the winter solstice</td><td align="center" valign="middle" >from 9/23 to 12/21</td><td align="center" valign="middle" >132</td></tr></tbody></table></table-wrap><p><xref ref-type="fig" rid="fig2">Figure 2</xref> shows the correlation coefficients between the eight gas concentrations G<sub>E1</sub>, G<sub>E2</sub>, G<sub>E3</sub>, G<sub>E4</sub>, G<sub>C1</sub>, G<sub>C2</sub>, G<sub>C3</sub>, G<sub>C4</sub> and the periodic approximation curve.

Here, the denominators e1, e3, c1, and c3 are the amplitudes of the gas concentrations of the biosensors in the lower layer, and the numerators e2, e4, c2, and c4 are the amplitudes of the gas concentrations of the biosensors in the upper layer. The results showed a difference between the lower and upper layers with respect to the amplitude of the circadian rhythm. The ratio between controls, e4/e3 (black squares) and c4/c3 (gray squares), always had a ratio value greater than 1, indicating that the amplitude of the upper layer was greater than that of the lower layer. The value of the ratio was particularly large in SPR. From this we understood that in the control, the gas release activity was greater in the upper G<sub>E4</sub>, G<sub>C4</sub> than in the lower G<sub>E3</sub>, G<sub>C3</sub>. Possible reasons for this are that during the experiment, the upper layer was exposed to more lighting than the lower layer, and the temperature might be higher in the upper layer than in the lower layer. Furthermore, we considered why the ratio was greater in the SPR. The reason is that the biological response to gas release was more active in the SPR than in other seasons. On the other hand, the ratio of the amplitudes of the biosensors G<sub>E1</sub> and G<sub>E2</sub> affected by the pyramid power, e2/e1 (red squares), had values less than 1 from WTR to SMR, and the activity of gas emission in the upper layer G<sub>E2</sub> appeared to be suppressed compared to that in the lower layer G<sub>E1</sub>. The ratio c2/c1 (blue squares) of the amplitudes of the biosensors G<sub>C1</sub> and G<sub>C2</sub> affected by the Bio-Entanglement changed qualitatively the same as e2/e1 affected by the pyramid power.

For the pyramid power effect, the ratio e1/e3 between the lower layers was always larger than 1 in value. It was especially large in SPR. The ratio e2/e4 between the upper layers had a value less than 1 from WTR to SMR and a value greater than 1 in AUT. For the Bio-Entanglement effect, the ratio c1/c3 between the lower layers was qualitatively almost equal to the effect of the pyramid power. The ratio of c2/c4 between the upper layers was also qualitatively equal to the effect of the pyramid power, with values less than 1 from WTR to SMR.

CONSIDERATION</title><p>We analyzed the effects of the pyramid power and the Bio-Entanglement on the amplitude of the periodic approximation curve representing the circadian rhythm of gas concentration in Section 5.2, and in Section 5.3 we analyzed the effects of the pyramid power and the Bio-Entanglement on the correlation coefficient between gas concentration and its circadian rhythm. The results showed that the amplitude and correlation coefficients were affected by the pyramid power and the Bio-Entanglement, and that the two effects were qualitatively equal. Therefore, we compared <xref ref-type="fig" rid="fig7">Figure 7</xref>, which shows the amplitude ratio, with <xref ref-type="fig" rid="fig9">Figure 9</xref>, which shows the ratio of correlation coefficients, and found that they agreed with very high accuracy (<xref ref-type="fig" rid="fig1">Figure 1</xref>0). In <xref ref-type="fig" rid="fig1">Figure 1</xref>0(a) and <xref ref-type="fig" rid="fig1">Figure 1</xref>0(b), the correlation between the amplitude ratios and</p><p>correlation coefficient ratios was calculated, yielding correlation coefficients of 0.954 and 0.946 with p-values of p = 6.8 &#215; 10<sup>−11</sup> and 2.9 &#215; 10<sup>−10</sup>. We discuss the fact that we have seen such agreement despite the seemingly different concepts of amplitude and correlation coefficient. Assuming that the variation of the eight gas concentration data G<sub>E1</sub>, G<sub>E2</sub>, G<sub>E3</sub>, G<sub>E4</sub>, G<sub>C1</sub>, G<sub>C2</sub>, G<sub>C3</sub>, and G<sub>C4</sub> are almost the same, the following can be expected. Comparing the case where the amplitude of the periodic approximation curve is small and the case where the amplitude is large, the correlation coefficient between the data and the periodic approximation curve will be larger when the amplitude is large, and the correlation coefficient between the data and the periodic approximation curve will be smaller when the amplitude is small. Therefore, the amplitude ratio and correlation coefficient ratio are considered to be proportional. <xref ref-type="fig" rid="fig1">Figure 1</xref>1 shows the actual variation in gas concentration data. The vertical axis is the normalized gas concentration (ppm), subtracting the average from each gas concentration.

The conclusions we reached are summarized in 1) - 3) below.</p><p>1) The pyramid power and the Bio-Entanglement affected the phase of the periodic approximation curve representing the circadian rhythm of gas concentration (<xref ref-type="fig" rid="fig5">Figure 5</xref> and <xref ref-type="fig" rid="fig6">Figure 6</xref>).</p><p>At the PS apex, the phase of the circadian rhythm of the gas concentrations G<sub>E1</sub> (lower layer) and G<sub>E2</sub> (upper layer) was shifted 12.5 min to the left of the phase of G<sub>E2</sub> relative to that of G<sub>E1</sub>, due to the pyramid power. At the calibration control point, the phase of the circadian rhythm of the gas concentrations G<sub>C1</sub> (lower layer) and G<sub>C2</sub> (upper layer) was shifted 13.5 min to the left of the phase of G<sub>C2</sub> relative to that of G<sub>C1</sub>, due to the Bio-Entanglement. For G<sub>E2</sub> (upper layer) and G<sub>E4</sub> (upper layer) at the PS apex and the calibration control point, the phase of G<sub>E2</sub> was shifted 43 min to the left from G<sub>E4</sub> by the pyramid power.</p><p>2) The pyramid power and the Bio-Entanglement affected the amplitude of the periodic approximation curve representing the circadian rhythm of gas concentration (<xref ref-type="fig" rid="fig7">Figure 7</xref>).</p><p>For the amplitude of the circadian rhythm, we identified differential effects on the lower and upper layers. In the control, (lower layer amplitude e3, c3) &lt; (upper layer amplitude e4, c4), and in the case of the pyramid power and the Bio-Entanglement influence, the trend was opposite to the control, with a tendency for (lower layer amplitude e1, c1) &gt; (upper layer amplitude e2, c2).</p><p>The effects of the pyramid power and the Bio-Entanglement were clarified from the amplitude ratio between the lower and lower layers and the amplitude ratio between the upper and upper layers. The amplitudes were (PS lower e1) &gt; (control lower e3) between the lower layers, and (PS upper e2) &lt; (control upper e4) between the upper layers, with the lower and upper layers having different results depending on the pyramid power. In addition, due to the Bio-Entanglement, the amplitude was almost given as (c1) &gt; (c3) between the lower layers, and almost given as (c2) &lt; (c4) between the upper layers, with the lower and upper layers having different results similar to the pyramid power. From this we concluded that the pyramid power and the Bio-Entanglement for the amplitude of the circadian rhythm of gas concentration were qualitatively the same and proportional in magnitude.</p><p>3) The pyramid power and the Bio-Entanglement affected the correlation coefficient between gas concentration and the periodic approximation curve representing the circadian rhythm of gas concentration (<xref ref-type="fig" rid="fig8">Figure 8</xref> and <xref ref-type="fig" rid="fig9">Figure 9</xref>).</p><p>For the correlation coefficient of the circadian rhythm, we identified differential effects on the lower and upper layers. In the control, (lower layer correlation coefficient g<sub>E3</sub>, g<sub>C3</sub>) &lt; (upper layer correlation coefficient g<sub>E4</sub>, g<sub>C4</sub>), and in the case of the pyramid power and the Bio-Entanglement influence, the trend was opposite to the control, with a tendency for (lower layer correlation coefficient g<sub>E1</sub>, g<sub>C1</sub>) &gt; (upper layer correlation coefficient g<sub>E2</sub>, g<sub>C2</sub>).</p><p>The effects of the pyramid power and the Bio-Entanglement were clarified from the correlation coefficient ratio between the lower and lower layers and the correlation coefficient ratio between the upper and upper layers. The correlation coefficient was (PS lower g<sub>E1</sub>) &gt; (control lower g<sub>E3</sub>) between the lower layers, and (PS upper g<sub>E2</sub>) &lt; (control upper g<sub>E4</sub>) between the upper layers, with the lower and upper layers having different results depending on the pyramid power. In addition, due to the Bio-Entanglement, the correlation coefficient was almost given by (g<sub>C1</sub>) &gt; (g<sub>C3</sub>) between the lower layers, and almost given by (g<sub>C2</sub>) &lt; (g<sub>C4</sub>) between the upper layers, with the lower and upper layers having different results similar to the pyramid power. Then we found that compared to the control, the pyramid power and the Bio-Entanglement reversed the magnitude of the correlation coefficient between the lower and upper layers. From this we understood that the effects of the pyramid power and the Bio-Entanglement on the correlation coefficient between gas concentration and its circadian rhythm were qualitatively the same.</p><p>At the time we published our previous paper [<xref ref-type="bibr" rid="scirp.122792-ref25">25</xref>], we understood that the pyramid power and the Bio-Entanglement had no effect on the number of cycles of the circadian rhythm of gas concentration. We have, however, identified effects on the phase, amplitude, and correlation coefficient of the periodic approximation curve representing the circadian rhythm. As more experimental data become available, for example, more yellow areas in <xref ref-type="table" rid="table3">Table 3</xref>, we believe it will be possible to find new characteristics related to the pyramid power and the Bio-Entanglement.</p><p>We previously demonstrated that the pyramid power and the Bio-Entanglement affected the gas concentration ratio. In contrast, in this paper we demonstrated for the first time that the pyramid power and the Bio-Entanglement affected time (phase difference). We expect that our research results will be widely accepted in the future and will become the foundation for a new research field in science, with a wide range of applications.</p></sec><sec id="s8"><title>ACKNOWLEDGEMENTS</title><p>This research was funded by Science Peace Culture Foundation (SPC-F), (Chairman of the Board of Directors: Dr. Mikio Yamamoto).</p></sec><sec id="s9"><title>CONFLICTS OF INTEREST</title><p>The authors declare no conflicts of interest regarding the publication of this paper.</p></sec><sec id="s10"><title>REFERENCES</title></sec></body><back><ref-list><title>References</title><ref id="scirp.122792-ref1"><label>1</label><mixed-citation publication-type="other" xlink:type="simple">Goodspeed, D., Liu, J.D., Chehab, E.W., Sheng, Z., Francisco, M., Kliebenstein, D.J. and Braam, J.
