the application of traditional nmo-correction techniques in the processing of seismic data may result in severe distortion. this distortion is observed as a decrease in frequency content (nmo stretch). this may be seen as the source of problems in the processing with stretch. in this paper, cnmo method is applied which doesn't have the `stretching effects' of conventional nmo correcti...

It is proposed that the apparent positive acceleration of the cosmological scale factor is due to the vacuum energy of an incomplete chiral phase transition in a hidden SU(2) sector. Constraints from primordial nucleosynthesis imply that the present metastable phase is in a substantially supercooled state. It is argued that massless chiral condensates can substantially enhance the possibility o...
