Topological defects on solutions of the non-relativistic equation for extended double ring-shaped potential
《Communications in Theoretical Physics》2024年第8期29-43,共15页Badredine Boudjedaa Faizuddin Ahmed 
In this study, we focus into the non-relativistic wave equation described by the Schrodinger equation, specifically considering angular-dependent potentials within the context of a topological defect background genera...

Source-independent wave-equation based microseismic source location using traveltime inversion
《Earthquake Science》2018年第2期100-109,共10页Songqin Nong Chao Huang Liangguo Dong 
A new source location method using wave-equation based traveltime inversion is proposed to locate microseismic events accurately. With a sourceindependent strategy, microseismic events can be located independently reg...
