Unification of sparse Bayesian learning algorithms for electromagnetic brain imaging with the majorization minimization framework

NeuroImage, 2021
Methods for electro- or magnetoencephalography (EEG/MEG) based brain source imaging (BSI) using sparse Bayesian learning (SBL) have been demonstrated to achieve excellent performance in situations with low numbers of distinct active sources, such as ...

Inverse Scattering and the Geroch Group

, 2013
We study the integrability of gravity-matter systems in D=2 spatial dimensions with matter related to a symmetric space G/K using the well-known linear systems of Belinski-Zakharov (BZ) and Breitenlohner-Maison (BM).

Weak group inverse

Open Mathematics, 2018
In this paper, we introduce the weak group inverse (called as the WG inverse in the present paper) for square complex matrices of an arbitrary index, and give some of its characterizations and properties.

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

AIMS 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

Trace inequalities for positive semidefinite matrices

Discussiones Mathematicae - General Algebra and Applications, 2017
Certain trace inequalities for positive definite matrices are generalized for positive semidefinite matrices using the notion of the group generalized inverse.

Further characterizations of the weak group inverse of matrices and the weak group matrix

AIMS Mathematics, 2021
This paper is devoted to consider some new characteristics and properties of the weak group inverse and the weak group matrix. First, we characterize the weak group inverse of a square matrix based on its range space and null space.

Data-driven structural transition detection using vibration monitoring and LSTM networks

AIMS Mathematics
Structural health monitoring (SHM) is essential for ensuring the safety and durability of civil infrastructure. Traditional SHM approaches, based on manual inspections or threshold-based analyses, often fail to detect early or subtle structural changes ...
