Multiple prediction through inversion (MPI) is an effective method for seismic multiple attenuation. The research in this thesis aims to make the MPI method more practical for both free-surface and internal multiple attenuation. For free-surface multiple attenuation, the MPI sch…

In the archetypal bacterial transcription, the multi-subunit core RNA polymerase (RNAP) is specifically bound to the promoter through the sigma factor (σ), forming a closed complex where DNA remains double-stranded. The promoter DNA is initially spontaneously melted by the σ fac…
