This is an opportunity to recall the long history of this phenomenon in the traditions of different civilizations, to evaluate Chinese efforts, 30-40 years ago, to use this phenomenon for earthquake prediction, and to judge its state of acceptance in modem science. An effort is made to introduce this phenomenon as a research field of modem bionics. The timing is favorable since, increasingly, infrared thermal anomalies, monitored from satellite, suggesting litho-atmospheric processes, are found to precede earthquakes. They were unexpected by seismologists and are here suggested to essentially reflect the energy conversion patterns responsible for the signals monitored by animals. The aim is to learn from animals in the long term how natural disasters can better be anticipated, and how simple technical warning systems can be developed. Some challenges are analyzed. One is interpretation of the nature of energy release prior to the main earthquake disaster resulting in ＂macro-anomaly＂ precursors, another is better to understand the effect on animal senses. The role of non-linear cooperative phenomena including tsunamitype waves is emphasized.展开更多
Low-spin signature inversion has been systematically observed throughout the chart of nuclides in the πg9/2(■) vg9/2, πh11/2(■)vh11/2, πh11/2(■)vh13/2, and πh9/2(■) vi13/2, configurations. Considering the high...Low-spin signature inversion has been systematically observed throughout the chart of nuclides in the πg9/2(■) vg9/2, πh11/2(■)vh11/2, πh11/2(■)vh13/2, and πh9/2(■) vi13/2, configurations. Considering the high-j nature of these configurations, we have tried to find the similar signature inversion phenomenon in the πi13/2 (■) vi13/2, bands展开更多
