An Extended Krylov Subspace Method for Decoding Edge‐Based Compressed Images by Homogeneous Diffusion

open access: yesNumerical Linear Algebra with Applications, Volume 33, Issue 1, February 2026.
ABSTRACT The heat equation is often used to inpaint dropped data in inpainting‐based lossy compression schemes. We propose an alternative way to numerically solve the heat equation by an extended Krylov subspace method. The method is very efficient with respect to the computation of the solution of the heat equation at large times.

Virulence Regulation and Lifestyle Transitions: The Role of c‐di‐GMP and Two‐Component Systems in Erwinia amylovora and Their Evolutionary Context Within Enterobacterales

open access: yesMolecular Plant Pathology, Volume 27, Issue 2, February 2026.
Erwinia amylovora infects apple blossoms by activating the T3SS, then spreads systemically via amylovoran‐mediated biofilms. Transitions between motile and sessile states are regulated by key two‐component systems and c‐di‐GMP. This review summarises infection biology, virulence factors, regulatory networks and evolutionary insights underlying fire ...

Flow of Elastoviscous Nanofluid Through an Elongating Surface With Dissipative Heat: A Confluent Hypergeometric Solution

open access: yesAsia-Pacific Journal of Chemical Engineering, Volume 21, Issue 1, January/February 2026.
ABSTRACT Thermal energy transport likely through polymer extrusion, cooling of metallic plates, and chemical processing equipment relating to the flow of viscoelastic nanofluid has a greater role in engineering because of its elastic characteristics.

A matter arising: When should inflammatory and autoimmune rheumatic diseases be considered ‘early’?

open access: yesEuropean Journal of Clinical Investigation, Volume 56, Issue 1, January 2026.
Timely recognition of inflammatory and autoimmune rheumatic diseases (IARDs) is important to optimize the early diagnosis with tailored interventions and possible prevention of irreversible organ damage. This narrative review provides an update by summarizing the advances in identifying the early stages of rheumatoid arthritis, systemic sclerosis and ...

CGMN and CARP-CG on clusters of multi-core CPUs [PDF]

open access: yes, 2015
In 1979, Bj\"orck and Elfving published some remarkably robust CG-accelerated row projection methods. More recently, Gordon and Gordon proposed a parallel variant called CARP-CG (Component-Averaged Row Projections). We adopt their idea for the inter-node

A unified thermo‐chemo‐mechanical model for passive, active, and interfacial oxidation of silicon carbide

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 1, January 2026.
Abstract Silicon carbide (SiC) is a promising material for hypersonic thermal protection systems, but its complex oxidation behavior—marked by transitions between passive, active, and interfacial bubbling regimes—can lead to catastrophic failure. Existing SiC models typically focus exclusively on either passive or active oxidation.

An approach to the numerical studies of partial differential equations (PDEs) [PDF]

open access: yes, 2012
In todays’ engineering practices, numerical methods are integral to the development of solutions for the myriad of engineering problems. The key role that numerical methods play is to come up with approximate solutions to complicated engineering problems

Module structure of Weyl algebras

open access: yesJournal of the London Mathematical Society, Volume 113, Issue 1, January 2026.
Abstract The seminal paper (Stafford, J. Lond. Math. Soc. (2) 18 (1978), no. 3, 429–442) was a major step forward in our understanding of Weyl algebras. Beginning with Serre's Theorem on free summands of projective modules and Bass' Stable Range Theorem in commutative algebra, we attempt to trace the origins of this work and explain how it led to ...

Online learning to accelerate nonlinear PDE solvers: applied to multiphase porous media flow [PDF]

open access: yes
We propose a novel type of nonlinear solver acceleration for systems of nonlinear partial differential equations (PDEs) that is based on online/adaptive learning. It is applied in the context of multiphase flow in porous media.
