The Complete Quotient Ring of Images of Semilocal Prüfer Domains
, 1977 It is well known that the complete quotient ring of a Noetherian ring coincides with its classical quotient ring, as shown in Akiba [1]. But in general, the structure of the complete quotient ring of a given ring is largely unknown.

On the rings whose injective right modules are max-projective
Recently, right almost-QF (respectively, max-QF) rings that is the rings whose injective right modules are R-projective (respectively, max-projective) were studied by the first two authors. In this paper, our aim is to give some further characterizations

Residual Chemical Shift Anisotropies in the Structure Determination of Small Molecules
Magnetic Resonance in Chemistry, Volume 64, Issue 3, Page 286-311, March 2026.Plasma neutrophil elastase(ELANE) was markedly elevated in patients with alcohol use disorder, indicating a dysregulated protease‐antiprotease inflammatory balance characterised by decreased SERPINA3. ELANE showed excellent diagnostic specificity(AUC = 0.8683), supporting its potential utility as a neuroinflammatory biomarker for AUD.

Generalization of a theorem of Artin-Pfister to arbitrary semilocal rings, and related topics
Journal of Algebra, 1975 (*) with t = (tj in) running through all multi-indices with coordinates 0 or 1 and with coefficients c{ which are sums of squares. In the special case r = 1, ax = 1, this is Artin's well known theorem that totally positive elements are sums of squares [l,Satz 1], and in fact Pfister deduces his theorem from Artin's theorem.

Confined Chemistry in Space: Zeolite‐Supported Fe13 Nanoclusters Modulate CS Reactivity
Small Structures, Volume 7, Issue 3, March 2026.The study explores how an Fe13 cluster confined in chabazite reshapes the reaction of CS and H2 under astrochemical conditions. Confinement promotes C–S bond cleavage over hydrogenation, directing chemistry toward CH4 and H2S formation. Additional CS enables CS2 and C2 species. Microkinetic analysis identifies protoplanetary environments where zeolites

Low Parsons–Zobel slope of metal–solution interfaces: A theoretical comparison of three causes
AIChE Journal, Volume 72, Issue 2, February 2026.Abstract Rational design of electrochemical energy conversion and storage devices hinges on a fundamental understanding of the electrical double layer (EDL) at the electrode–electrolyte interface. The classical Gouy–Chapman–Stern model of EDL predicts a unity Parsons–Zobel (PZ) slope, which is derived from the relation between inverse measured ...

Journal of Computational Chemistry, Volume 47, Issue 3, 30 January 2026.A new local hybrid functional, LH25nP, is reported, that uses a neural‐network local mixing function for the position‐dependence of exact‐exchange admixture trained with a human‐designed strong‐correlation factor. It thereby escapes the usual zero‐sum game between delocalization and static‐correlation errors.

Torsion classes of extended Dynkin quivers over commutative rings
Bulletin of the London Mathematical Society, Volume 58, Issue 1, January 2026.Abstract For a Noetherian R$R$‐algebra Λ$\Lambda$, there is a canonical inclusion torsΛ→∏p∈SpecRtors(κ(p)Λ)$\mathop {\mathsf {tors}}\Lambda \rightarrow \prod _{\mathfrak {p}\in \operatorname{Spec}R}\mathop {\mathsf {tors}}(\kappa (\mathfrak {p})\Lambda)$, and each element in the image satisfies a certain compatibility condition.

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.

Chemistry–Methods, Volume 5, Issue 12, November 2025.Expanded porphyrins, with their flexible structures and rich redox chemistry, offer a powerful platform to explore how aromaticity shapes molecular properties. This review introduces a multidimensional framework to quantify Hückel and Möbius aromaticity and examines its impact on the spectroscopic behavior across redox‐ and topology‐controlled expanded
