Kitai's Criterion for composition operators
We present a general and natural framework to study the dynamics of composition operators on spaces of measurable functions, in which we then reconsider the characterizations for hypercyclic and mixing composition operators obtained by Bayart, Darji and Pires.

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.

This article presents a characterization of non-singular measurable transformation, denoted as TT, mapping from Ω\Omega to itself, along with bicomplex-valued BC{\mathbb{BC}}-measurable function uu defined on Ω\Omega , which induces a weighted ...

We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Classification of Multioperations of Rank 2 by E-precomplete Sets
In this paper multioperations defined on a two-element set and their closure operator based on composition operator and the equality predicate branching operator is considered. The composition operator is based on union of sets.

A Schwarz Lemma and Composition Operators [PDF]
Let \(D\) be a domain in a complex Banach space \(E\) and let \(\triangle\) be the open unit disc in the complex plane. The authors first prove that \(\log((2 + d_D)/(2- d_D))\) coincides with the Carathéodory pseudo-distance \(C_D\) on \(D\), where the pseudo-distance \(d_D\) is defined by \(d_D(z,w):= \sup\{| f(z)-f(w)| : f : D \to \triangle ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Diversity and complexity in neural organoids
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.
