Direct Inversion Method of Brittleness Parameters Based on Reweighted Lp-Norm
Applied Sciences, 2022 Brittleness is an important factor that indicates shale properties, as well as fracturability, and it can be well-represented using the elasticity parameter Eρ. Seismic inversion allows direct access to the Eρ ofbrittleness parameters.

On the Extension of Inverse Scattering Method [PDF]
Progress of Theoretical Physics, 1974 Summary: The inverse scattering method is extended into \(n\times n\) matrix form so as to include wider classes of nonlinear differential equations. As a mathematical foundation for the extension, the inverse scattering problem for the \(n\times n\) Schrodinger equation is discussed and the Gelfand-Levitan-Marcenko equation for the system is derived ...

Water Temperature Observation by Coastal Acoustic Tomography in Artificial Upwelling Area
Sensors, 2019 Artificial upwelling is a geoengineering method to repair and improve marine ecosystems, and its operation requires long-term and continuous temperature field observation. However, existing methods are rarely seen to accomplish such observation.

Stability of Methods for Matrix Inversion [PDF]
IMA Journal of Numerical Analysis, 1992 The numerical stability of several matrix inversion methods is analyzed. For triangular matrices it is shown that the unblocked methods satisfy pleasing bounds on the left and right residuals. However for one of the block methods it is necessary to convert a matrix multiplication into the solution of a multiple right-hand side triangular system in ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT A lethal round‐cell malignancy with an MN1::ZNF341 fusion has recently been reported in three infants. Here, we describe four further tumors, three in newborns (including monozygotic twins), and one in an adolescent. Detailed clinical, radiological, and histopathological data differentiate these tumors from their main mimics, neuroblastoma and
