Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis
FEBS Letters, EarlyView.Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

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.

FEBS Letters, EarlyView.Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

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.

Path-induced closure operators on graphs for defining digital Jordan surfaces
Open Mathematics, 2019 Given a simple graph with the vertex set X, we discuss a closure operator on X induced by a set of paths with identical lengths in the graph. We introduce a certain set of paths of the same length in the 2-adjacency graph on the digital line ℤ and ...

Modelling stem cell differentiation related processes—A practical overview for biologists
FEBS Letters, EarlyView.Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

CLOSURE #8: Kieler e-Journal für Comicforschung [PDF]
, 2021 Was verbindet zwei Panels, die nebeneinander stehen? Die Antwort auf diese Frage lautet zumeist ›eine Erzählung.‹ So verlangt zum Beispiel Scott McCloud, ›einige der Geheimnisse zu lüften, die die unsichtbare Kunst des Comic-Erzählens umgeben‹ (74).

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.
