nonstretch nmo by constant nmo correction (cnmo)
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...
متن کاملnmo correction with nonstretch nmo method
the application of nmo (normal moveout) has been recognized as an effective method of generating quasi-zero-offset traces in traditional common-midpoint processing. artifacts of the nmo method relate to the nmo-stretch effects. conventional application of normal-moveout correction to a common-midpoint (cmp) reflection generates a stretch that increases with offset and decreases with zero-offset...
متن کاملFinding NMO
Neuromyelitis optica (NMO) is a severe inflammatory demyelinating disease with lesions found primarily in the spinal cord and optic nerve. Although originally classified as a subtype of multiple sclerosis (MS), the finding of autoantibodies against the astrocyte water channel aquaporin-4 (AQ4) has defined this as a specific autoimmune disorder. Important questions have arisen as to how AQ4 anti...
متن کاملCurrent concept of neuromyelitis optica (NMO) and NMO spectrum disorders.
Neuromyelitis optica (NMO) has been described as a disease clinically characterised by severe optic neuritis (ON) and transverse myelitis (TM). Other features of NMO include female preponderance, longitudinally extensive spinal cord lesions (>3 vertebral segments), and absence of oligoclonal IgG bands . In spite of these differences from multiple sclerosis (MS), the relationship between NMO and...
متن کاملAquaporin 4-specific T cells and NMO-IgG cause primary retinal damage in experimental NMO/SD
Neuromyelitis optica/spectrum disorder (NMO/SD) is a severe, inflammatory disease of the central nervous system (CNS). In the majority of patients, it is associated with the presence of pathogenic serum autoantibodies (the so-called NMO-IgGs) directed against the water channel aquaporin 4 (AQP4), and with the formation of large, astrocyte-destructive lesions in spinal cord and optic nerves. A l...
