Subdyadic square functions and applications to weighted harmonic analysis [PDF]
, 2016 Through the study of novel variants of the classical Littlewood-Paley-Stein $g$-functions, we obtain pointwise estimates for broad classes of highly-singular Fourier multipliers on $\mathbb{R}^d$ satisfying regularity hypotheses adapted to fine ...

Survey on the Figà–Talamanca Herz algebra
Mathematics, 2019 This paper presents a self contained approach to the theory of convolution operators on locally compact groups (both commutative and non commutative) based on the use of the Figà−Talamanca Herz algebras.

Semispectral measures as convolutions and their moment operators
, 2008 The moment operators of a semispectral measure having the structure of the convolution of a positive measure and a semispectral measure are studied, with paying attention to the natural domains of these unbounded operators.

A note on certain convolution operators
, 2013 In this note we consider a certain class of convolution operators acting on the L_p spaces of the one dimensional torus. We prove that the identity minus such an operator is nicely invertible on the subspace of functions with mean zero.Comment: 10 ...

Hypercyclic algebras for D-multiples of convolution operators [PDF]
, 2018 It is shown in this short note the existence, for each nonzero member of the ideal of D-multiples of convolution operators acting on the space of entire functions, of a scalar multiple of it supporting a hypercyclic algebra.Plan Andaluz de Investigación (

An Approximation Method for Convolution Calderón-Zygmund Operators
Abstract and Applied Analysis, 2013 We present an approximation method for convolution Calderón-Zygmund operators. We give a uniform approximation accuracy of the operators on the endpoint Triebel-Lizorkin space F˙1 0;q ...

Collaborative Convolution Operators for Real-Time Coarse-to-Fine Tracking
IEEE Access, 2018 Discriminative correlation filter (DCF) has attracted enormous popularity among the tracking community. Standard DCF based trackers easily achieve real-time tracking speed but significantly suffer from the boundary effects.

Molecular Oncology, EarlyView.This study characterizes the responses of primary acute myeloid leukemia (AML) patient samples to the MCL‐1 inhibitor MIK665. The results revealed that monocytic differentiation is associated with MIK665 sensitivity. Conversely, elevated ABCB1 expression is a potential biomarker of resistance to the treatment, which can be overcome by the combination ...

Continuity of Operators Intertwining with Convolution Operators
Journal of Functional Analysis, 2002 The authors give an affirmative solution to the following problem of \textit{Laursen} and \textit{Neumann} [An Introduction to Local Spectral Theory, London Mathematical Society Monographs, New Series, Vol. 20, Oxford University Press (2000; Zbl 0957.47004)]: Suppose that \(\mu\) and \(\nu\) are bounded complex valued measures on a locally compact ...

Molecular Oncology, EarlyView.Nanosecond infrared laser (NIRL) low‐volume sampling combined with shotgun lipidomics uncovers distinct lipidome alterations in oropharyngeal squamous cell carcinoma (OPSCC) of the palatine tonsil. Several lipid species consistently differentiate tumor from healthy tissue, highlighting their potential as diagnostic markers.
