In order to achieve an effective approximation solution for solving discrete ill-conditioned problems, Golub, Hansen, and O’Leary used Tikhonov regularization and the total least squares (TRTLS) method, where the bidiagonal technique is considered

For large-scale problems, how to establish an algorithm with high accuracy and stability is particularly important. In this paper, the Householder bidiagonalization total least squares (HBITLS) algorithm and nonlinear iterative partial least squares

We are concerned with determining values of , for which there exist nodal solutions of the boundary value problem , where is a sign-changing function, with . The proof of our main results is based upon global bifurcation techniques.

Based on the theory of cone and operators, this paper concerned with the existence of unique positive solution for a class of nonlinear fractional boundary value problem with two parameters (one is called an eigenvalue parameter and another is a dist

We study the asymptotic behavior of solutions to the non-autonomous stochastic plate equation driven by additive noise defined on unbounded domains. We first prove the uniform estimates of solutions, and then establish the existence and upper semicon

This note complements and improves a norm inequality for accretive-dissipative matrices recently obtained by Kittaneh and Sakkijha. We provide two different extensions. Our proofs feature the effec...

Background: Intratympanic and intravenous gadolinium administration is used to visualise endolymphatic hydrops. Aims/objectives: The goal of this study was to compare the image quality between intratympanic (IT-method) and intravenous (IV-method) gad

PURPOSE The discrimination between neuromyelitis optica (NMO)- and multiple sclerosis (MS)-related acute optic neuritis (ON) after the first presentation is difficult in clinical practice. Through a comparison with diffusion-weighted imaging using re

PURPOSE In clinical practice, acute optic neuritis (ON) associated with the development of neuromyelitis optica (NMO) after the first attack is often indistinguishable from that associated with multiple sclerosis (MS). We aimed to determine the optim
