A preconditioned AOR iterative scheme for systems of linear equations with L-matrics
Open Mathematics, 2019 In this paper we investigate theoretically and numerically the new preconditioned method to accelerate over-relaxation (AOR) and succesive over-relaxation (SOR) schemes, which are used to the large sparse linear systems.

A Polynomial Preconditioner for the CMRH Algorithm [PDF]
, 2011 National Natural Science Foundation of China [10961010]Many large and sparse linear systems can be solved efficiently by restarted GMRES and CMRH methods Sadok 1999. The CMRH (m) method is less expensive and requires slightly less storage than GMRES (m).

Advanced Functional Materials, EarlyView.Cell therapies typically rely on cold‐chain logistics and cryopreservation, limiting access and compromising cell quality. Here, a dual‐chamber device separates an oxygen‐supplying chamber from a hyaluronic acid cargo chamber, sustaining oxygen delivery for over 70 h and enabling ambient‐temperature shipment.

A hybrid interface preconditioner for monolithic fluid–structure interaction solvers
Advanced Modeling and Simulation in Engineering Sciences, 2020 We propose a hybrid interface preconditioner for the monolithic solution of surface-coupled problems. Powerful preconditioning techniques are crucial when it comes to solving large monolithic systems of linear equations efficiently, especially when ...

Design and analysis of Toeplitz preconditioners [PDF]
IEEE Transactions on Signal Processing, 1992 The preconditioned conjugate gradient method (PCG) for solving symmetric positive definite Toeplitz systems \(Ax=b\) can be derived by iteratively minimizing the quadratic form \(x^ TAx/2-b^ Tx\) with the conjugate gradient method and preconditioning. Since the convergence rate of the conjugate gradient method depends on the spectrum of the matrix \(A\)

Advanced Materials, EarlyView.Asymmetric lamellar templating at the perovskite/C60 interface is achieved using a laterally polarized indole spacer. Surface anchoring and Ind–Ind assembly form a π‐rich lamellar interphase that supports uniform C60 contact formation, suppresses recombination, preserves electron extraction, and enables certified high‐efficiency cells and modules with ...

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 ...

Transient Cytoskeletal Anisotropy Encodes Short‐Term Mechanical Memory in Glioblastoma Cells
Advanced Materials, EarlyView.The same mechanical deformation can produce distinct cytoskeletal states depending on loading history. Experiments and constitutive modeling reveal that transient actin–vimentin anisotropy stores mechanical information and governs short‐term mechanical memory in glioblastoma cells.
