Left and Right Operator Rings of a Γ Ring in Terms of Rough Fuzzy Ideals
Axioms, 2023 The relationship between Rough Set (RS) and algebraic systems has been long studied by mathematicians. RS is a growing research area that encourages studies into both real-world applications and the theory itself.

On tensor stable operator ideals.
Michigan Mathematical Journal, 1989 An operator ideal \({\mathfrak A}\) is tensor stable with respect to a tensor norm \(\alpha\), provided that for all operators S,T belonging to \({\mathfrak A}\) also \(S{\tilde \oplus}_{\alpha}T\) belongs to \({\mathfrak A}\). The authors show that any non-proper Banach-operator ideal with \(\sup_{n}A(id_{\ell^ n_{\infty}})=\infty\), A being the ideal

Condensation of the singularities in the theory of operator ideals
Journal of Numerical Analysis and Approximation Theory, 2004 In the present paper there are given some applications of the principle of condensation of the singularities of families of nonnegative functions established by W. W. Breckner in 1984. They reveal Baire category information on certain subsets of a normed

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?
FEBS Letters, EarlyView.This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Interior Operators Generated by Ideals in Complete Domains
Mathematics, 2021 This article presents some properties of a special class of interior operators generated by ideals. The mathematical framework is given by complete domains, namely complete posets in which the set of minimal elements is a basis.

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Dominated Ideals and Baire Ideals in Complete Domains
MathematicsWe consider an operator Gi,I generated by a given interior operator i and an ideal I. Among the properties of the operator Gi,I, two properties denoted by Pi and Qi are remarkable.

Uniform Convergence and Spectra of Operators in a Class of Fréchet Spaces
Abstract and Applied Analysis, 2014 Well-known Banach space results (e.g., due to J. Koliha and Y. Katznelson/L. Tzafriri), which relate conditions on the spectrum of a bounded operator T to the operator norm convergence of certain sequences of operators generated by T, are extended to ...

Mechanisms of IgE‐mediated food allergy and the role of allergen‐specific B cells
FEBS Letters, EarlyView.Food allergy arises when allergen‐specific B cells preferentially produce immunoglobulin E (IgE) antibodies against harmless foods. This article explains the mechanisms driving IgE‐mediated reactions, highlights the central role of these B cells, and discusses how natural tolerance (NT) and oral immunotherapy (OIT) can reshape allergic immune responses.
