Essential norm of Cesàro operators on L p and Cesàro spaces
, 2017 In this paper, we consider the Cesàro-mean operator Γ acting on some Banach spaces of measurable functions on (0, 1), as well as its discrete version on some sequences spaces. We compute the essential norm of this operator on L p ([0, 1]), for p ∈ (1, +∞]

Generalized Stević–Sharma operators on weighted Dirichlet spaces
Demonstratio MathematicaIn this paper, we investigate the order boundedness of the generalized Stević–Sharma operators between weighted Dirichlet spaces. We also characterize the boundedness, essential norm and compactness of this class of operators acting from weighted ...

Essential norm of substitution operators on L p spaces
Indian Journal of Pure and Applied Mathematics, 2012 Let \((X,\Sigma, \mu)\) be a \(\sigma\)-finite measure space. Suppose that \(\varphi:X \to X\) is a non-singular transformation, that is, \(\mu\circ \varphi^{-1} \ll \mu\), and let \(u\) be a \(\Sigma\)-measurable function on \(X\). By the Radon-Nikodým theorem, for every \(f\in L^1\) there exists a \(\mu\)-unique function \(\tilde{f}_{\varphi}^{u}\in ...

The microbiome in human skin aging
FEBS Letters, EarlyView.Age‐related skin changes encompass the well‐known visible phenotypic alterations, together with microbiome dysbiosis and a series of molecular aging hallmarks. These hallmarks characterize not only a fully stablished aged phenotype but also the skin aging process itself.

CTS and normativity: the essentials of preemptive counter-terrorism interventions [PDF]
Critical Studies on Terrorism, 2019 This article critically assesses calls for ‘normativity’ in counter-radicalisation and counter-extremism, and suggests that aligning with hegemonic narratives about securing the ‘pre-crime’ space is problematic in a context of emancipation. Utilising interviews with a number of Prevent officials (including Channel ‘de-radicalisation’ mentors), the ...

Essential Norm Of Generalized Integration Operator On Fock Space
, 2022 In the past two decades, different properties of the integral operator have been studied in several functional spaces. In particular, on Fock spaces boundedness and compactness of the operator were studied by (Constantin, 2012 and Mengestie, 2013 ...

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry
FEBS Letters, EarlyView.EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...

Synergistic perspectives—How single‐molecule biophysics complement biochemical understanding
FEBS Letters, EarlyView.In this review, we discuss how ensemble biochemistry and single‐molecule approaches are complementary, outline commonly used single‐molecule techniques, and illustrate their relevance through two representative case studies: chromatin organization by SMC complexes and pathway choice during DNA double‐strand break repair.

FEBS Letters, EarlyView.Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...
