A generalization of T. Chan’s preconditioner
Linear Algebra and its Applications, 2005 The authors propose a new preconditioner for solving linear systems by the preconditioned conjugate gradient (PCG) method. The operation cost and convergence of the PCG method are discussed. Numerical examples are also provided.

An Efficient Parallel Three-Level Preconditioner for Linear Partial Differential Equations [PDF]
, 1998 The primary motivation of this research is to develop and investigate parallel preconditioners for linear elliptic partial differential equations. Three preconditioners are studied: block-Jacobi preconditioner (BJ), a two-level tangential preconditioner (

Advanced Science, EarlyView.Photobiomodulated microglia release engineered extracellular vesicles that deliver UFL1 to the injured spinal cord. UFL1 competitively binds p53 with MDM2, inhibiting p53 ubiquitination and stabilizing p53 signaling. This dual mechanism simultaneously promotes anti‐inflammatory microglial polarization and directs neural stem cell differentiation toward

An Element-by-Element Multilevel Block ILU Preconditioner Using GLAS [PDF]
, 2010 We investigate a new element-by-element multilevel block-ILU preconditioner that combines the advantages of element-by-element (EBE) and incomplete LU-factorization (ILU) preconditioners.

Mesoporous‐Shell Monolayer Plasmonic Architecture Enables Quantitative and Decision‐Guided SERS
Advanced Science, EarlyView.Mesoporous‐shell‐regulated molecular transport combined with monolayer hotspot determinism transforms surface‐enhanced Raman spectroscopy (SERS) from ultrasensitive detection into quantitative and decision‐guided molecular sensing. ABSTRACT Quantitative surface‐enhanced Raman spectroscopy (SERS) has long been impeded by stochastic hotspot formation ...

Advanced Science, EarlyView.Chronic stress drives autophagy‐mediated β2‐AR degradation, impairing antiviral immunity and promoting poxvirus lethality. Lycorine directly stabilizes β2‐AR to restore host defense, suppress excessive inflammation and improve survival. ABSTRACT Psychological stress is a pervasive yet poorly understood modulator of infectious disease outcomes. Here, we

Advanced Science, EarlyView.Amphiphilic sulfonated chitosan nanoparticles buffer endo/lysosomal acidity in microglia by limiting V‐ATPase membrane recruitment and restoring endosomal homeostasis. Following systemic administration, they accumulate in the ischemic hemisphere partly through association with infiltrating immune cells, suppress TLR3/IRF3 and TLR4/NF‐κB signaling ...

Monolayer MoS2 With Ultrahigh Piezoelectricity: From ALD Dose Control to Device Performance
Advanced Science, EarlyView.This study demonstrates that controlling precursor dosages in atomic layer deposition (ALD) serves to regulate ultrathin oxide quality, which in turn determines sulfurization behavior and MoS2 monolayer continuity. The resulting continuous, low‐defect monolayers enable improved piezoelectric performance and support a flexible slippage sensor, linking ...
