Radical preservation and the finitistic dimension
Bulletin of the London Mathematical Society, Volume 58, Issue 1, January 2026.Abstract We introduce the notion of radical preservation and prove that a radical‐preserving homomorphism of left artinian rings of finite projective dimension with superfluous kernel reflects the finiteness of the little finitistic, big finitistic, and global dimension.

The structure of finite meadows [PDF]
, 2009 A meadow is a commutative ring with a total inverse operator satisfying 0^{-1}=0. We show that the class of finite meadows is the closure of the class of Galois fields under finite products.

Concepts in Magnetic Resonance Part A, Volume 2026, Issue 1, 2026.Resting‐state functional MRI (rsfMRI) analysis relies on complex mathematical operations whose properties and pitfalls are often poorly understood, leading to interpretational errors and suboptimal processing choices. This work presents novel mathematical insights for rsfMRI analysis through three key contributions: (1) a unified geometric framework ...

Strong Resolving Graphs of U‐Clean Graphs of Finite Commutative Rings
Journal of Mathematics, Volume 2026, Issue 1, 2026.Let R be a finite commutative ring with identity 1. The U‐clean graph U‐Cl(R) of a ring R is a simple undirected graph with vertices are of the form (e, u), where e is a nonzero idempotent and u is a unit of R, and two distinct vertices (e, u), (f, v) of U‐Cl(R) are adjacent if and only if e = f = 1 or uv = 1.

A Spatial Lag Design Model Only in Treatments Using Perpendicular Projection Operators
Modelling and Simulation in Engineering, Volume 2026, Issue 1, 2026.Spatial modeling literature typically presents models that incorporate spatial lags within classical spatial regression frameworks. This research proposes a design model that integrates both treatment and block effects, selectively incorporating the spatial lag only in the submatrix associated with treatments.

On idempotent convexities and idempotent barycenter maps
Topology and its ApplicationsWe consider an isomorphism between the idempotent convexity based on the maximum and the addition operations and the idempotent measure convexity on the maximum and the multiplication operations. We use this isomorphism to investigate topological properties of the barycenter map related to the maximum and the multiplication operations.
