Exact lattice bosonization of finite N matrix quantum mechanics and c = 1

Journal of High Energy Physics
We describe a new exact lattice bosonization of matrix quantum mechanics (equivalently of non-relativistic fermions) that is valid for arbitrary rank N of the matrix.

Matrix Pencil Optimal Iterative Algorithms and Restarted Versions for Linear Matrix Equation and Pseudoinverse

Mathematics
We derive a double-optimal iterative algorithm (DOIA) in an m-degree matrix pencil Krylov subspace to solve a rectangular linear matrix equation. Expressing the iterative solution in a matrix pencil and using two optimization techniques, we determine the

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

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.

A Columnwise Update Algorithm for Sparse Stochastic Matrix Factorization

, 2022
Nonnegative matrix factorization arises widely in machine learning and data analysis. In this paper, for a given factorization of rank r, we consider the sparse stochastic matrix factorization (SSMF) of decomposing a prescribed m-by-n stochastic matrix V

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

Molecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

Matrix-M adjuvant triggers inflammasome activation and enables antigen cross-presentation through induction of lysosomal membrane permeabilization

npj Vaccines
Matrix-M® adjuvant, containing saponins, delivers a potent adjuvant effect and good safety profile. Given that Matrix-M is composed of Matrix-A and Matrix-C particles, comprising different saponin fractions, understanding their distinct roles can provide

Matrix models as non-local hidden variables theories [PDF]

, 2001
It is shown that the matrix models which give non-perturbative definitions of string and M theory may be interpreted as non-local hidden variables theories in which the quantum observables are the eigenvalues of the matrices while their entries are the ...

On regular splittings of an M-matrix

Linear Algebra and its Applications, 1989
Some results on regular splittings of M-matrices are proved. The study is motivated by a recent work of \textit{H. Schneider} [ibid. 58, 407-424 (1984; Zbl 0561.65020)]. It is shown, first, that if A is a nonsingular M-matrix and \(A=M-N\) is a regular splitting then this splitting is a graph compatible one, and if A is just an M-matrix but \(A=M-N ...

A stable test to check if a matrix is a nonsingular $M$-matrix [PDF]

Mathematics of Computation, 2004
A real matrix with non-positive off-diagonal elements is called a \(Z\)-matrix. Non-singular \(M\)-matrices form a subclass of \(Z\)-matrices. In this paper, a test to check the non-singularity of an \(M\)-matrix is presented such that the related growth factor is bounded above by \(n-1\). In the worst case, the proposed test adds \(O(n^2)\) elementary

COMP–PMEPA1 axis promotes epithelial‐to‐mesenchymal transition in breast cancer cells

Molecular Oncology, EarlyView.
This study reveals that cartilage oligomeric matrix protein (COMP) promotes epithelial‐to‐mesenchymal transition (EMT) in breast cancer. We identify PMEPA1 (protein TMEPAI) as a novel COMP‐binding partner that mediates EMT via binding to the TSP domains of COMP, establishing the COMP–PMEPA1 axis as a key EMT driver in breast cancer.
