A method for fractional Volterra integro-differential equations by Laguerre polynomials [PDF]

open access: goldAdvances in Difference Equations, 2018
The main purpose of this study is to present an approximation method based on the Laguerre polynomials for fractional linear Volterra integro-differential equations. This method transforms the integro-differential equation to a system of linear algebraic

Rician Likelihood Loss for Quantitative MRI With Self-Supervised Deep Learning. [PDF]

open access: yesNMR Biomed
We introduce a numerically accurate and stable negative log Rician (NLR) likelihood loss for quantitative MR imaging with self‐supervised deep learning. Self‐supervised neural networks trained with the NLR loss have reduced bias in intra‐voxel incoherent motion diffusion coefficient at low signal‐to‐noise ratio (SNR) compared to the traditional mean ...

Some relations on Humbert matrix polynomials [PDF]

open access: yesMathematica Bohemica, 2016
The Humbert matrix polynomials were first studied by Khammash and Shehata (2012). Our goal is to derive some of their basic relations involving the Humbert matrix polynomials and then study several generating matrix functions, hypergeometric matrix ...
