Analele Stiintifice ale Universitatii Ovidius Constanta: Seria MatematicaIn this article, we study relationships between closure operators and hoops. We investigate the properties of closure operators and hoop-homomorphism on hoops. We show that the image of a closure operator on a hoop is isomorphic to a quotient hoop.

Counterexamples related to unbounded paranormal operators
Examples and Counterexamples, 2021 In this paper, we give an example of a densely defined non-closable paranormal operator. Then, we give another example of a densely defined closable paranormal operator whose closure fails to be paranormal.

Liver organoids: modelling complexity in homeostasis and disease
FEBS Letters, EarlyView.Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses

The δ-Sharp Operator in Ideal Topological Spaces and Its Induced Topology
Journal of MathematicsIn the framework of ideal topological spaces, this paper introduces a new operator called the δ-sharp operator. We examine its fundamental properties and compare its behavior with both the classical sharp operator and the δ∗-operator.

Emerging experimental and computational methods for studying redox‐regulated structural transitions
FEBS Letters, EarlyView.Redox reactions can reshape proteins and alter how they behave in cells, with important consequences for health and disease. This review explores emerging experimental and computational approaches for discovering these redox‐sensitive protein switches, revealing their structural effects, and predicting their behavior, opening new opportunities to ...

Synergistic perspectives—How single‐molecule biophysics complement biochemical understanding
FEBS Letters, EarlyView.In this review, we discuss how ensemble biochemistry and single‐molecule approaches are complementary, outline commonly used single‐molecule techniques, and illustrate their relevance through two representative case studies: chromatin organization by SMC complexes and pathway choice during DNA double‐strand break repair.

Journal of Mathematical Analysis and Applications, 2001 For a set \(X\) and a complete residuated lattice \(L\), the author introduces and investigates graduated closure operators \(L^X\to L^X\), closure systems \(\subseteq L^X\) and systems of ``almost closed fuzzy sets'' \(L^X\to L\) in \(X\). He shows that they characterize each other and studies the relationship to fuzzy Galois connections.

Axiomatic systems of Alexandrov spaces
Journal of Hebei University of Science and Technology, 2017 In order to study internel axiomatic systems and ordered features of Alexandrov spaces, with the help of some existed results in topology and locale theory, by restricting the related structures into Alexandrov setting, some equivalent descriptions are ...

FEBS Letters, EarlyView.Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...
