Generalization of Snell's Law for the propagation of acoustic waves in elliptically anisotropic media

open access: yesAIMS Mathematics
In seismic data processing, both in inversion (Inverse Processing) and modeling (Direct Processing), it is essential to consider anisotropy to unravel the geological structure of the subsoil. Besides, in most cases, the macroscopic model of anisotropy in

The Division Ring Over Conjugate Product

open access: yesIEEE Access, 2019
In this paper, we investigate the rational fractions in the framework of conjugate product and establish a division ring. Some conjugate properties on the proposed division ring are obtained, and the similarity and consimilarity properties are ...

MoDL: Model-Based Deep Learning Architecture for Inverse Problems [PDF]

open access: yesIEEE Transactions on Medical Imaging, 2017
We introduce a model-based image reconstruction framework with a convolution neural network (CNN)-based regularization prior. The proposed formulation provides a systematic approach for deriving deep architectures for inverse problems with the arbitrary ...

Spin Model for Inverse Melting and Inverse Glass Transition

open access: yes, 2004
A spin model that displays inverse melting and inverse glass transition is presented and analyzed. Strong degeneracy of the interacting states of an individual spin leads to entropic preference of the "ferromagnetic" phase, while lower energy associated ...

Alternative proofs of some formulas for two tridiagonal determinants

open access: yesActa Universitatis Sapientiae: Mathematica, 2018
In the paper, the authors provide five alternative proofs of two formulas for a tridiagonal determinant, supply a detailed proof of the inverse of the corresponding tridiagonal matrix, and provide a proof for a formula of another tridiagonal determinant.

Elasticities and the Inverse Hyperbolic Sine Transformation

open access: yesOxford Bulletin of Economics and Statistics, 2020
Applied econometricians frequently apply the inverse hyperbolic sine (or arcsinh) transformation to a variable because it approximates the natural logarithm of that variable and allows retaining zero‐valued observations.

Interesting Explicit Expressions of Determinants and Inverse Matrices for Foeplitz and Loeplitz Matrices

open access: yesMathematics, 2019
Foeplitz and Loeplitz matrices are Toeplitz matrices with entries being Fibonacci and Lucas numbers, respectively. In this paper, explicit expressions of determinants and inverse matrices of Foeplitz and Loeplitz matrices are studied.
