Linear Combinations of Composition Operators on the Bloch Spaces [PDF]

Canadian Journal of Mathematics, 2011
Abstract We characterize the compactness of linear combinations of analytic composition operators on the Bloch space. We also study their boundedness and compactness on the little Bloch space.

Function‐driven design of a surrogate interleukin‐2 receptor ligand

FEBS Letters, EarlyView.
Interleukin (IL)‐2 signaling can be achieved and precisely fine‐tuned through the affinity, distance, and orientation of the heterodimeric receptors with their ligands. We designed a biased IL‐2 surrogate ligand that selectively promotes effector T and natural killer cell activation and differentiation. Interleukin (IL) receptors play a pivotal role in

On saturation of one linear method for summing Fourier series given by a function set

Researches in Mathematics
The paper considers the issues of saturation in the spaces $C$ and $L_p$, $p\in [1;\infty )$ of the biharmonic Poisson operator, in particular, the order and class of saturation are found.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
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.

Adjoints of Semigroups of Linear Operators in Banach Spaces

Journal of Mathematical Analysis and Applications, 1993
The authors prove the complex generalization of the well-known Phillips theorem on the adjoint semigroups for a recently studied new class of semigroups [\textit{I. Miyadera} and \textit{N. Tanaka}, J. Math. Anal. Appl. 143, No. 2, 358-378 (1989; Zbl 0697.47039)], precisely semigroups \(\{T(t): T\geq 0\}\) on a Banach space \(X\) satisfying two ...

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

FEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Cebyšev’s type inequalities for positive linear maps of selfadjoint operators in Hilbert spaces [PDF]

Mathematica Moravica, 2017
Some inequalities for positive linear maps of continuous synchronous (asynchronous) functions of selfadjoint linear operators in Hilbert spaces, under suitable assumptions for the involved operators, are given.

C0-semigroups of linear operators on some ultrametric Banach spaces

International Journal of Mathematics and Mathematical Sciences, 2006
C0-semigroups of linear operators play a crucial role in the solvability of evolution equations in the classical context. This paper is concerned with a brief conceptualization of C0-semigroups on (ultrametric) free Banach spaces E.

Potential therapeutic targeting of BKCa channels in glioblastoma treatment

Molecular Oncology, EarlyView.
This review summarizes current insights into the role of BKCa and mitoBKCa channels in glioblastoma biology, their potential classification as oncochannels, and the emerging pharmacological strategies targeting these channels, emphasizing the translational challenges in developing BKCa‐directed therapies for glioblastoma treatment.
