Sparse Approximate Inverse Preconditioners
, 2023 AbstractConsider a preconditioner M based on an incomplete LU (or Cholesky) factorization of a matrix A. M−1, which represents an approximation of A−1, is applied by performing forward and back substitution steps; this can present a computational bottleneck.

Targeting Adipose Tissue Function Protects Against Heart Failure with Preserved Ejection Fraction
Advanced Science, EarlyView.This study explores the role adipose tissue (AT) phenotypes have in determining cardiovascular outcomes in an obesity‐related heart failure with preserved ejection fraction (HFpEF) model. Pharmacological induction of thermogenesis promoted resilience to HFpEF‐induced remodeling of AT and conferred cardioprotection. Surgical and genetic models confirmed

Advanced Science, EarlyView.A predictive model for 3D printability is developed by integrating rheological analysis, including the Large Amplitude Oscillatory Shear (LAOS) test, with machine learning. With prediction errors under 10%, the model shows that post‐extrusion recovery controls horizontal printability, while high‐strain‐rate nozzle flow dictates vertical printability ...

A New Hybrid Preconditioner for the Interior Point Method
Trends in Computational and Applied Mathematics, 2019 This study aims to improve the computation of the search direction in the primal-dual Interior Point Method through preconditioned iterative methods. It is about a hybrid approach that combines the Controlled Cholesky Factorization preconditioner and ...

A Microbiota‐ and IL‐15‐Dependent Innate‐Like B Cell Progenitor Expressing E4BP4
Advanced Science, EarlyView.This work identifies CD3.NKp46.CD19.NK1.1. NK‐B cells enriched in PDK1‐deficient yet present in wild‐type bone marrow. IL‐15 (via CD122) and TLR9‐microbiota signaling maintain their E4BP4 expression. These cells demonstrate innate immunity, preferentially differentiate into B cells, and unveil a novel microbiota‐ and IL‐15‐dependent regulatory pathway ...

Multipreconditioned GMRES for simulating stochastic automata networks
Open Mathematics, 2018 Stochastic Automata Networks (SANs) have a large amount of applications in modelling queueing systems and communication systems. To find the steady state probability distribution of the SANs, it often needs to solve linear systems which involve their ...
