The first evidence of asymmetric upward and downward persistence in the global sea surface temperature anomaly (SSTA) is revealed from the observations with the asymmetric detrended fluctuation analysis (A-DFA) method. Global distributions of the scaling exponents which quantify the degree of...

The implications of an electronic coupling model in high TC superconductors of YBCO are discussed in which the pairing mechanism is based upon the ionic bonding. Specifically,the bonding reaction Cu + O [rlhar2] Cu-- resonates at a frequency of I2πh̵; in the CuO planes, where I = 0.4 eV is the...
