We classify initial-value problems for extended KdV-Burgers equations via generalized conditional symmetries. These equations can be reduced to Cauchy problems
We report on the photovoltaic properties of La0.7Sr0.3MnO3/ZnO heterojunction fabricated by pulsed laser deposition methods.Nanosecond photovoltaic pulses are o
Thermal diffusion of dopants is investigated in the process of generating the graded-index profile of plastic optical fibres. Because the diffusion coefficient
We present the calculation of total cross sections for positron scattering by Rb at intermediate energies by using the coupled-channel optical method, in which
High-quality type-Ⅱa gem diamond crystals are successfully synthesized in a Ni70Mn25Co5-C system by temperature gradient method (TGM) at about 5.5 GPa and 1560
