A new eigenvalue bound for the Hadamard product of an M-matrix and an inverse M-matrix

The Electronic Journal of Linear Algebra, 2012
If A and B are nn nonsingular M-matrices, a new lower bound for the minimum eigenvalue (AB 1 ) for the Hadamard product of A and B 1 is derived. This bound improves the result of (R. Huang. Some inequalities for the Hadamard product and the Fan product of matrices. Linear Algebra Appl., 428:1551-1559, 2008.).

Safety and efficacy of malaria vaccine candidate R21/Matrix-M in African children: a multicentre, double-blind, randomised, phase 3 trial [PDF]

Background Recently, we found that a new malaria vaccine, R21/Matrix-M, had over 75% efficacy against clinical malaria with seasonal administration in a phase 2b trial in Burkina Faso.

Confinement/deconfinement transition in the D0-brane matrix model — A signature of M-theory?

Journal of High Energy Physics, 2022
We study the confinement/deconfinement transition in the D0-brane matrix model (often called the BFSS matrix model) and its one-parameter deformation (the BMN matrix model) numerically by lattice Monte Carlo simulations.

ON $M$-MATRIX AND INVERSE $M$-MATRIX COMPLETION PROBLEMS

Far East Journal of Mathematical Sciences (FJMS)
Matrix completion problems play a crucial role in situations where only partial information about a matrix is known, but the complete matrix must satisfy specific structural and spectral properties. These problems aim to determine how to complete such incomplete matrices while preserving desired characteristics.

Estimates for the minimum eigenvalue of an M-matrix

Journal of Physics: Conference Series, 2023
Abstract New sharper lower bounds for the minimal eigenvalues of symmetric M-matrices and nonsymmetric M-matrices are proposed by constructing two increasing sequences. By contrasting the proposed instances with the related findings, two instances are offered to demonstrate the effectiveness of the technique.

A Graph Classification Method Based on Support Vector Machines and Locality-Sensitive Hashing

IEEE Access
Graphs classification is a relevant problem that arises in many disciplines. Using graphs directly instead of vectorization allows exploiting the intrinsic representations of the data.

Several new inequalities for the minimum eigenvalue of M-matrices

Journal of Inequalities and Applications, 2016
Several convergent sequences of the lower bounds for the minimum eigenvalue of M-matrices are given. It is proved that these sequences are monotone increasing and improve some existing results.

Comparative Drug Response Profiling in Neuroblastoma Cell Lines and Patient‐Derived Tumor Organoids

Pediatric Blood &Cancer, EarlyView.
ABSTRACT High‐risk neuroblastoma remains a leading cause of pediatric cancer mortality, and improved preclinical models are needed to guide therapeutic developments. We screened seven high‐risk neuroblastoma cell lines and three patient‐derived tumor organoids with 528 compounds alongside bone marrow controls, and compared them with external datasets ...

ON CONDITIONS FOR MATRICES T SUCH THAT T-I AND I-T^(-1) ARE INVERSE H-MATRICES*

Barekeng
In this article, we study an analogue of a classical result for M-matrices: if T - I is an invertible M-matrix, then both T and I - T-1 are also invertible M-matrices. We extend this implication to a broader class—inverse H-matrices.
