Complete stagnation of gmres

Linear Algebra and its Applications, 2003
In their introduction, the authors state, ``We study an oddity: the class of problems for which the generalized minimal residual (GMRES) algorithm, when started with the initial guess \(x^{(0)}=0\) and using exact arithmetic, computes \(m\) iterates \(x^{(1)}=\cdots=x^{(m)}=0\) without making any progress at all.

Research progress on the metabolic transformation of Shenling Baizhu San under the influence of the gut microbiota

Advanced Chinese Medicine, EarlyView.
Abstract The gut microbiota plays a pivotal role in maintaining host metabolic homeostasis and overall physiological functions. Shenling Baizhu San (SLBZS), a time‐honored classical prescription for tonifying Qi, strengthening the spleen, removing dampness, and arresting diarrhea, has shown broad clinical efficacy in digestive disorders.

Long‐Term Temporal Profile of Motor Recovery After Intracerebral Hemorrhage

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Limited data is available to describe the temporal profile of long‐term recovery over 1 year after the stroke in patients with spontaneous intracerebral hemorrhage (ICH). Methods A registered multicentral cohort was conducted to consecutively include non‐herniated supratentorial ICH patients from November 2013 to January 2023 ...

A Simulative Approach for the Prediction of Mesoscale Residual Stress Fields in Solution‐Strengthened Ferritic Ductile Iron

Advanced Engineering Materials, EarlyView.
This study presents a 3D representative volume element‐based simulation approach to predict mesoscopic residual stress and strain fields in silicon solid solution‐strengthened ductile cast iron. By modeling phase transformation kinetics with an enhanced Johnson–Mehl–Avrami–Kolmogorov model, the effects of varying cooling rates on residual stresses are ...
