Sequential and parallel preconditioners for large-scale integral-equation problems [PDF]

, 2007
Date of Conference: 30-31 August 2007Conference Name: Computational Electromagnetics Workshop, IEEE 2007For efficient solutions of integral-equation methods via the multilevel fast multipole algorithm (MLFMA), effective preconditioners are required.

Biolipid Film‐Fused Electrochemiluminescence for Multipurpose In Situ Bioassays

Advanced Science, EarlyView.
An ECL‐emissive, membrane‐interactive scaffold was fabricated, and facilely fused with natural and non‐native phospholipids into multifactorial mimicries of cytomembranes and vesicles for in vitro representative membrane‐process probing. Such a biointerface‐based, state‐sensitive ECL paradigm not only pinpointed proximal phenomena, including channeling

The Tau method and a new preconditioner

Journal of Computational and Applied Mathematics, 2004
The authors present a formulation of the tau method that makes use of fact that the derivatives of the Chebyshev and Legendre polynomials are Gegenbauer polynomials of higher index. This allows them to find suitable preconditioners. Numerical results are included.

PIEZO1 is Required for Acute Myeloid Leukemia Progression and Leukemia Stem Cell Maintenance via HIF1A‐SLC7A11 Axis‐Mediated Ferroptosis Defense

Advanced Science, EarlyView.
This study identifies the mechanosensor PIEZO1 as a key factor in promoting acute myeloid leukemia progression and uncovers a ferroptosis defense system mediated by PIEZO1‐HIF1A‐SLC7A11 axis that is essential for leukemia stem cell maintenance. This ferroptotic defense system may represent a unique vulnerability for leukemia stem cells, providing a ...

Modified Preconditioned GAOR Methods for Systems of Linear Equations

Journal of Applied Mathematics, 2013
Three kinds of preconditioners are proposed to accelerate the generalized AOR (GAOR) method for the linear system from the generalized least squares problem. The convergence and comparison results are obtained.

Null-space preconditioners for saddle point problems [PDF]

, 2015
The null-space method is a technique that has been used for many years to reduce a saddle point system to a smaller, easier to solve, symmetric positive-definite system. This method can be understood as a block factorization of the system.
