The total quantum statistical entropy of Reissner-Nordstrom (RN) black holes is evaluated. The spacetime of the black holes is divided into three regions-region
A Gunn active layer is used as an X electron probe to detect the X tunnelling current in the GaAs-AlAs heterostructure, from which a new heterostructure interva
The nearly single phase (R0.4Pr0.6)0.5Ca0.5Ba2Cu3O7-δ compounds (R = La, Pr, Nd, Sm, Eu, Gd and Y) with Tc about 100 K were prepared under high pressure and hi
We consider the quantization of LC (inductance-capacitance) circuit at a finite temperature T as any practical circuits always produce Joule heat except for sup
