We consider the nonlinear Dirac equation (NLD) with time dependent ex-ternal electro-magnetic potentials, involving a dimensionless parameter ε∈(0,1] which is
The authors employ the high-density resistivity method to image the subsurface structure of a moun-tain in Erdaojiang District, Tonghua City, Jilin Province, Ch
Complexity measures for multisequences over finite fields,such as the joint linear complexity and the k-error joint linear complexity,play an important role in
Because of various complicated factors in seismic data collection, the random noise of seismic data is too difficult to avoid. This random noise reduces the qua
By determining the distribution and extent of geological structures surrounding the Mingyan Tunnel, Xicheng Town, Helong City, Jilin Province, we can evaluate t
