Weighted Differentiation Composition Operator from Logarithmic Bloch Spaces to Zygmund-Type Spaces

Abstract and Applied Analysis, 2014
Let H(𝔻) denote the space of all holomorphic functions on the unit disk 𝔻 of ℂ, u∈H(𝔻) and let  n be a positive integer, φ a holomorphic self-map of 𝔻, and μ a weight.

Interpreting the effects of DNA polymerase variants at the structural level

Molecular Oncology, EarlyView.
Using MAVISp and molecular dynamics simulations, we analyzed over 60 000 missense variants in POLE and POLD1 from ClinVar, COSMIC, cBioPortal, and saturation mutagenesis. Identified mechanistic indicators, including stability, binding, and long‐range, enable structural interpretation, providing ACMG‐like evidence for possible reclassification of VUS ...

On the stability index for weighted composition operators

Journal of Approximation Theory, 2010
An operator \(S:C(X)\to C(Y)\) is said to be a weighted composition operator (denoted \(S\in \mathbf {WCM}(X,Y)\)) if there exists \(a\in C(Y)\) and a map \(h:Y\to X\), continuous on \(\{y\in Y: a(y)\not=0\}\), such that \((Sf)(y)= a(y) f(h(y))\) for every \(f\in C(X)\) and \(y\in Y\). For \(\varepsilon\geq0\), the linear operator \(T:C(X)\to C(Y)\) is

Developmental programmes drive cellular plasticity, disease progression and therapy resistance in lung adenocarcinoma

Molecular Oncology, EarlyView.
This study shows that lung adenocarcinomas exploit developmental branching morphogenesis to acquire a therapy resistant basal‐like tumour cell state. This process was found to be regulated by combined TP53 loss‐of‐function and type‐I interferon signalling, identifying a novel axis for biomarker and therapeutic target discovery.

Order-Bounded Difference in Weighted Composition Operators Between Fock Spaces

Mathematics
There are two aims in this paper. The first aim is to characterize the order-bounded weighted composition operators between Fock spaces, and the second is to further characterize the order-bounded difference in weighted composition operators between Fock

On Convexity of Composition and Multiplication Operators on Weighted Hardy Spaces

Abstract and Applied Analysis, 2009
A bounded linear operator T on a Hilbert space ℋ, satisfying ‖T2h‖2+‖h‖2≥2‖Th‖2 for every h∈ℋ, is called a convex operator. In this paper, we give necessary and sufficient conditions under which a convex composition operator on a large class of weighted ...

Spectra of Weighted Composition Operators with Quadratic Symbols

Concrete Operators, 2022
Previously, spectra of certain weighted composition operators W ѱ, φ on H2 were determined under one of two hypotheses: either φ converges under iteration to the Denjoy-Wolff point uniformly on all of 𝔻 rather than simply on compact subsets, or φ is ...

Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization

Molecular Oncology, EarlyView.
In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.
