Stimulated emission is a process during which an atomic system gives away energy to create coherent photon. It fundamental the operation of optical amplifier. Here we propose two mechanisms for amplifying AC spin currents in solid-state magnetic medium by stimulated pumping process. The first synchronous and consists phase-locked pulses that perturb precessing moment. second asynchronous driven...

Petrophysical evaluation of petroleum reservoirs is one of the most challenging tasks for hydrocarbon reserve determination. One critical petrophysical parameter is the water saturation which is normally calculated from Archie’s equation. Carbonate reservoirs, however, due to their complex mineralogy are not good candidates for Archie’s equation because Archie’s parameters are strongly dependen...

Abstract Overtopping flows in landslide dams erode and entrain materials on the dam surface resulting erosional features that undermine stability facilitate subsequent outburst flooding. A comprehensive understanding of evolution is therefore crucial for flood risk assessment hazard mitigation. In this research, we study mechanisms influence non‐uniform morphology breaches (i.e., non‐linear var...
