So far, they have reached 20 percent, "which is already very remarkable," Utzat says, already comparable to the coherences reached by other materials, such as atom-like fluorescent defects in diamond, that are already established systems and have been worked on much longer.
As shown in Figures 7(a), 7(b), 7(f), and 7(g), in the original data, all human subjects present high coherences in both low frequency band and high frequency band, which indicates a universal conductance induced consistency on scalp.
In this article, an attempt is made to investigate the discrepancies in the amplitudes (coherences) and phase angles of the cross spectra between sea echoes and interference and ionospheric layer echoes.
Surprisingly, quantum coherences are observed in the energy transfer of photosynthetic complexes, even at room temperature.Does nature exploit quantum concepts?
Table 1 Initial values, coherences and rms fit for different solutions.
Some coherences between cortical sites were correlated to the sizes of different regions in the corpus callosum.
So, when scientists want to analyze a complex molecule's structure, they routinely look for high-frequency signals from spin coherences. Those signals provide important structural clues about complicated molecules, such as the proximity of certain atoms and whether they are bonded.
In the explanatory search for understanding there have been three main attitudes, namely, the search for truth, the search for operational coherences, and the search for mythical causes that stand beyond our domain of ordinary experiences.
When one is attentive to the latter side, one becomes an `Alexandrian' who sees typology as simply a subspecies of allegory; when one attends to the former side, one becomes an `Antiochene' who privileges a mode of reading (theoria) that seems to preserve more of the integrity of the text--its textual particularities and larger narrative coherences.
Therefore, the integration of a work of art results in an artificial coherence. Polanyi emphasizes that there are two kinds of coherences: natural coherences, which we meet in nature, and artificial ones, which are contrived by man.
The researchers have engineered small molecules that support long-lived quantum coherences. Coherences are the macroscopically observable behavior of quantum superpositions.
For defining the interaction of different brain regions, the synchronization of EEG oscillations is an important and effective indicator which can be estimated by EEG coherence [24].
