Equivalence and perspectivity in Baer rings
, 1984 For certain Baer ∗-rings A (including all von Neumann algebras), the lattice L(A) of idempotent-generated principal right ideals has the following property: for idempotents e, f in A, the ideals eA, fA are isomorphic as right A-modules if and only if ...

On (co)pure Baer injective modules
, 2021 For a given class of R-modules Q, a module M is called Q-copure Baer injective if any map from a Q-copure left ideal of R into M can be extended to a map from R into M.

Laser Acupuncture on the Management of Xerostomia in Sjögren's Disease: A Randomized Clinical Trial
Oral Diseases, EarlyView.ABSTRACT Objectives This study evaluated the efficacy of photobiomodulation (PBM) at acupuncture points for managing xerostomia in patients with Sjögren's Disease. Material and Methods In this randomized, double‐blind clinical trial, 50 patients were assigned to PBM group (n = 22) or sham‐PBM group (n = 28).

Rings Whose Certain Modules are Dual Self-CS-Baer
In this work, we characterize some rings in terms of dual self-CS-Baer modules (briefly, ds-CS-Baer modules). We prove that any ring $R$ is a left and right artinian serial ring with $J^2(R)=0$ iff $R\\oplus M$ is ds-CS-Baer for every right $R$-module $M$

Psychology and Psychotherapy: Theory, Research and Practice, EarlyView.Abstract Purpose Attachment insecurity has been theorised to be associated with the development and maintenance of negative symptoms. Previous reviews examining the relationship between attachment insecurity and negative symptoms of psychosis have produced conflicting findings.

Baer semirings and Baer ∗-semirings of cone-preserving maps
, 1997 The study of π(K), the semiring of matrices which leave invariant the proper cone K, is continued in this paper. The definitions of Baer rings and Baer ∗-rings are extended to semirings, at least in the case of π(K).

Angewandte Chemie, Volume 138, Issue 25, 15 June 2026.Methyl substitution positions on the nylon‐6 backbone markedly affect crystallizability, thermomechanical properties, and recyclability of the resulting atactic nylon‐6 variants. While γ‐methyl substitution gives an amorphous nylon, all other four methyl‐substitution positions (α, β, δ, and ε) afford, unexpectedly, crystalline nylons, showing tacticity‐

Physiological Entomology, EarlyView.Oviposition and care decrease the total haemocyte concentration. Oviposition and care affect haemocyte type proportions. Serratia marcescens challenge does not affect the immune cell parameters. Abstract Reproduction and immunity are essential biological processes that compete for resources and energy.

Characterizations of rings and modules by means of lattices
, 1965 PhDIn this thesis we study the relationship between the lattice of submodules and the algebraic structure of a module. The key remark in our study will be the fact that the homomorphisms between two independent submadules of a module can be ...

A note on commutative Baer rings III [PDF]
Journal of the Australian Mathematical Society, 1973 If R is a commutative semiprime ring with identity Kist [4], [5] has shown that R can be embedded into a commutative Baer ring B(R), and has given some properties of this embedding. More recently Mewborn [7] has given a construction which embeds R into a commutative Baer ring with the stronger property that every annihilator is generated by an ...
