Numerical approximation of the field of values of the inverse of a large matrix [PDF]

, 2013
We consider the approximation of the field of values of the inverse of a large sparse matrix, without explicitly computing the inverse or using its action (i.e., accurately solving a linear system with this matrix).

Inverse M-matrix, a new characterization [PDF]

, 2020
In this article we present a new characterization of inverse M-matrices, inverse row diagonally dominant M-matrices and inverse row and column diagonally dominant M-matrices, based on the positivity of certain inner products.CONICYT, project BASAL ...

Operator Newton Method for Large-Scale Coupled Riccati Equations Arising from Jump Systems

Axioms
Consider a class of coupled discrete-time Riccati equations arising from jump systems. To compute their solutions when systems reach a steady state, we propose an operator Newton method and correspondingly establish its quadratic convergence under ...

Measuring Blood Plasma Glutamine Levels Using a Nanopore‐Based Sensor

Advanced Healthcare Materials, EarlyView.
Glutamine (GLN) is a biomarker useful for predicting toxic ammonia accumulation. Here, we used a biosensor based on the Cytolysin A (ClyA) nanopore coupled with the GLN‐specific protein substrate‐binding domain 2 (SBD2) to demonstrate real‐time measurement of GLN in blood plasma, highlighting the potential for future point‐of‐care applications ...

Solution to the General Inner-Outer and Spectral Factorization Problems [PDF]

, 1998
In this paper we solve two open problems in linear system theory: the computation of the spectral and inner-outer factorizations of a rational matrix G in the most general setting.

Antifolding activity of hsp60 couples protein import into the mitochondrial matrix with export to the intermembrane space [PDF]

, 1992
Cytochrome b2 reaches the intermembrane space of mitochondria by transport into the matrix followed by export across the inner membrane. While in the matrix, the protein interacts with hsp60, which arrests its folding prior to export.

Bandgap characteristics of four component periodic pile barriers in passive vibration isolation

Scientific Reports
Based on the local resonance theory, the vibration isolation performance of four-component periodic pile barriers consisting of a matrix, an outer pipe, an inner pipe, and a pile core was investigated using the finite element method (FEM).

Optimal Combination of the Splitting–Linearizing Method to SSOR and SAOR for Solving the System of Nonlinear Equations

Mathematics
The symmetric successive overrelaxation (SSOR) and symmetric accelerated overrelaxation (SAOR) are conventional iterative methods for solving linear equations. In this paper, novel approaches are presented by combining a splitting–linearizing method with

Topically Delivered Treg‐Attracting Microparticle‐Hydrogel Composites Recruit Regulatory T Cells and Limit Cardiac Injury After Severe Ischemia

Advanced Healthcare Materials, EarlyView.
CCL22‐releasing PLGA microparticles (MP) suspended in topically applied hydrogels (HEART) establish a sustained chemokine gradient at the injured myocardium. HEART recruits CCR4+ regulatory T cells, reduces infarct size and graft fibrosis, and improves cardiac function.
