On the Rings Whose Injective Modules Are Max-Projective
, 2023 In this thesis, for some classes of rings including, local, semilocal right semihereditary and right Noetherian right nonsingular, we obtain some conditions that equivalent to being right max-QF. For example, for a semilocal right semihereditary ring, we

Fragme∩t: An Open‐Source Framework for Multiscale Quantum Chemistry Based on Fragmentation
WIREs Computational Molecular Science, Volume 15, Issue 6, November/December 2025.This review introduces a new open‐source Python framework for rapid validation and prototyping of fragment‐based quantum chemistry methods, designed to be easy to deploy and modify by non‐experts. It is based on a foundation of the generalized many‐body expansion, which can encompass numerous fragmentation methods, combined with energy screening that ...

Dualizing Complexes over Noncommutative Local Rings
, 2001 We prove an existence theorem for dualizing complexes over noncommutative noetherian complete semilocal algebras, which generalizes Van den Bergh's existence theorem in the graded case. Using the dualizing complex, noncommutative versions of Bass theorem

Rationalising Exciton Interactions in Aggregates Based on the Transition Density
Chemistry – A European Journal, Volume 31, Issue 52, September 16, 2025.Exciton coupling in organic chromophores is revisited through the lens of the transition density. The presented formalism gives insight into the strength and sign of the coupling based on the relative arrangement of the lobes of the transition density explaining oscillations between H‐ and J‐aggregate behavior observed when two molecules are displaced ...

Homological Dimension of Skew Group Rings and Crossed Products
, 1994 In this paper we study the homological dimension of skew group rings and crossed products. A sufficient condition for R ∗ G, a crossed product, to have finite right global dimension is given, in terms of crossed products over simple Artinian factors of R

High Thermoelectric Performance in Low‐Cost Cu8SiSxSe6‐x Argyrodite
Advanced Functional Materials, Volume 35, Issue 34, August 22, 2025.This study discovers the great potential of Cu8SiSxSe6‐x argyrodites as new, low‐cost, Te‐free thermoelectric materials. The proposed defect scheme suppresses the phase transition, enhances the weighted mobility and optimizes the grain boundary contacts.

On sums of squares in local rings
, 2001 . Let A be a semilocal ring. We compare the set of positive semidefinite (psd) elements of A and the set of sums of squares in A. For psd f ∈ A, whether f is a sum of squares or not depends only on the behavior of f in an infinitesimal neighborhood of ...

Advanced Electronic Materials, Volume 11, Issue 9, June 2025.This paper provides a comprehensive review of the existing literature related to the fundamentals of gallium oxide (Ga2O3), growth methods, substrates, and particularly a focused examination of Ga2O3‐based heterojunctions. Particular attention has also been given to the state‐of‐the‐art Ga2O3‐based heterojunctions for photodetectors. The key challenges

Unitary groups with excellent S and entire E(u, L)
, 1982 Unitary groups of Hermitian forms with a hyperbolic rank at least one over local rings have been studied by D. G. James (J. Algebra 52 (1978), 354–363).

Structure of hyperbolic polynomial automorphisms of C2${\mathbb {C}^2}$ with disconnected Julia sets
Proceedings of the London Mathematical Society, Volume 130, Issue 6, June 2025.Abstract For a hyperbolic polynomial automorphism of C2$\mathbb {C}^2$ with a disconnected Julia set, and under a mild dissipativity condition, we give a topological description of the components of the Julia set. Namely, there are finitely many “quasi‐solenoids” that govern the asymptotic behavior of the orbits of all nontrivial components.
