Approximation operators based on preconcepts
Open Mathematics, 2020 Using the notion of preconcept, we generalize Pawlakâs approximation operators from a one-dimensional space to a two-dimensional space in a formal context.

The đ_{đ}-approximation property and unitarisability
Proceedings of the American Mathematical Society, 2022 We define a strengthening of the HaagerupâKraus approximation property by means of the subalgebras of HerzâSchur multipliers M d ( G ) M_d(G) ( d ⼠2 d\geq 2 ) introduced by Pisier.

FEBS Letters, EarlyView.The Ile181Asn variant of human UDPâxylose synthase (hUXS1), associated with a shortâstature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181AsnâhUXS1 retains catalytic activity similar to the wildâtype but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Topological structures of fuzzy neutrosophic rough sets [PDF]
Neutrosophic Sets and Systems, 2015 In this paper, we examine the fuzzy neutrosophic relation having a special property that can be equivalently characterised by the essential properties of the lower and upper fuzzy neutrosophic rough approximation operators. Further, we prove that the set

Finite approximation properties of Câ-modules
Illinois Journal of Mathematics, 2022 We study the notions of nuclearity and exactness for module maps on $C^{*}$-algebras which are $C^*$-module over another $C^*$-algebra with compatible actions and examine finite approximation properties of such $C^*$-modules. We prove module versions of the results of Kirchberg and Choi-Effros.

Homogeneous approximation property for continuous shearlet transforms in higher dimensions
Journal of Inequalities and Applications, 2016 This paper is concerned with the generalization of the homogeneous approximation property (HAP) for a continuous shearlet transform to higher dimensions. First, we give a pointwise convergence result on the inverse shearlet transform in higher dimensions.

Approximation properties and approximate identities of $A_{p}(G)$ [PDF]
Transactions of the American Mathematical Society, 2008 A Banach space is said to have the approximation property, if every compact operator is a limit of finite rank operators. The first systematic study of variants of the approximation property was initiated by \textit{A. Grothendieck} [Mem. Am. Math. Soc. 16 (1955; Zbl 0064.35501)].

Modeling hepatic fibrosis in TP53 knockout iPSCâderived human liver organoids
Molecular Oncology, EarlyView.This study developed iPSCâderived human liver organoids with TP53 gene knockout to model human liver fibrosis. These organoids showed elevated myofibroblast activation, early disease markers, and advanced fibrotic hallmarks. The use of profibrotic differentiation medium further amplified the fibrotic signature seen in the organoids.
