Complex symmetry of weighted composition operators on the Fock space [PDF]

, 2015
With the techniques of weighted composition operators, we introduce a new concept of general weighted composition conjugations on the Fock space F2(C) and completely solve the following problems: the description of weighted composition operators which ...

Solid Pseudopapillary Neoplasm of the Pancreas in Children and Adolescents: Expert Recommendations

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Solid pseudopapillary neoplasm of the pancreas (SPN) is a rare low‐grade malignant exocrine pancreatic tumor, mostly discovered during the second decade of life in females, with a very good prognosis, provided microscopically complete surgical excision is achieved.

Continuous Frames Under the Weighted Composition Operators on the Weighted Bergman Space

Axioms
We investigate the behavior of continuous frames in the weighted Bergman space Aα2 over the unit disc under the action of weighted composition operators. Motivated by developments in the discrete frame setting, we provide a comprehensive characterization

Differences of Composition Operators Followed by Differentiation between Weighted Banach Spaces of Holomorphic Functions

Abstract and Applied Analysis, 2013
We characterize the boundedness and compactness of differences of the composition operators followed by differentiation between weighted Banach spaces of holomorphic functions in the unit disk.

Ovarian Sex Cord Stromal Tumors in Children and Adolescents—The European Standard Clinical Practice Recommendations

Pediatric Blood &Cancer, EarlyView.
ABSTRACT As part of the European Cooperative Study Group for Paediatric Rare Tumours initiative, we developed standard clinical practice guidelines for ovarian sex cord stromal tumors, based on comprehensive national and international cohort analyses, literature review, and a final expert consensus conference.

Composition operators acting on weighted Dirichlet spaces [PDF]

, 2016
We study composition operators acting on weighted Dirichlet spaces. We obtain estimates for the essential norm, describe the membership in Schatten-Von Neumann ideals and characterize the composition operators with closed ...

Therapeutic Apheresis in Nigeria: A Multi‐Center Summary of Abstracts From the Inaugural Nigerian Society for Apheresis Scientific Meeting

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Therapeutic apheresis (TA) is an established treatment modality for hematologic, neurologic, and immunologic disorders, yet access remains severely limited in sub‐Saharan Africa. Donor apheresis, including platelet apheresis collection from healthy donors, represents an important complementary modality supporting blood product ...

WEIGHTED COMPOSITION OPERATORS AND DYNAMICAL SYSTEMS

Tamkang Journal of Mathematics, 1998
Let $X$ be a completely regular Hausdorff space, $E$ a Hausdorff locally convex topo­logical vector space, and $V$ a system of weights on $X$. Denote by $CV_b(X, E)$ ($CV_o(X, E)$) the weighted space of all continuous functions $f : X \to E$ such that $vf (X)$ is bounded in $E$ (respectively, $vf$ vanishes at infinity on $X$) for ...

Weighted composition operators and differences of composition operators between weighted Bergman spaces on the ball

Filomat, 2022
In this paper, we estimate essential norms of weighted composition operators and differences of two composition operators on the weighted Bergman spaces in the unit ball.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
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.
