A Derivative Hilbert operator acting from Bergman spaces to Hardy spaces

AIMS Mathematics, 2023
Let $ \mu $ be a positive Borel measure on the interval $ [0, 1) $. The Hankel matrix $ \mathcal{H}_{\mu} = (\mu_{n, k})_{n, k\geq 0} $ with entries $ \mu_{n, k} = \mu_{n+k} $, where $ \mu_{n} = \int_{[0, 1)}t^nd\mu(t) $, formally induces the operator as

Fourier representations in Bergman spaces

Journal of Mathematical Analysis and Applications, 2019
We consider a class of domains, generalizing the upper half-plane, and admitting rotational, translational and scaling symmetries, analogous to the half-plane. We prove Paley-Wiener type representations of functions in Bergman spaces of such domains with respect to each of these three groups of symmetries.

Radical Uncertainty and New Sector Emergence: An Action Theory of Co‐Creative Stakeholders

Strategic Change, EarlyView.
ABSTRACT For much of the past century, entrepreneurship scholars have sought to understand and assess the nature, role, and impact of uncertainty. While the sum total of this work has contributed valuable insights, radical uncertainty—characterized by dynamic conditions in which outcomes are unknowable at the time action must be taken—remains weakly ...

Commuting Toeplitz operators and H-Toeplitz operators on Bergman space

AIMS Mathematics
In this paper, we consider the H-Toeplitz and Toeplitz operators acting on the Bergman space. First, we describe the characterizations of commutativity of two H-Toeplitz operators with certain harmonic symbols.

Weighted Iterated Radial Composition Operators between Some Spaces of Holomorphic Functions on the Unit Ball

Abstract and Applied Analysis, 2010
The boundedness and compactness of weighted iterated radial composition operators from the mixed-norm space to the weighted-type space and the little weighted-type space on the unit ball are characterized here.

Effect of calcium chloride injection and freezing prior to wet aging on the meat quality of cull cows

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND In Brazil, the slaughter of female cattle, particularly older animals, has increased substantially. However, meat from this category presents limitations in terms of quality, mainly because of its toughness resulting from a high concentration of cross‐links between collagen fibers.

Direct Ambient Mass Spectrometry for Food, Beverage, and Agricultural Sample Analysis and Research

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Ambient and direct mass spectrometry (MS) methods are becoming increasingly used for the rapid analysis of food, beverage and agricultural samples. Novel ionization approaches combined with targeted, or untargeted workflows provide analytical outcomes within a greatly reduced time period compared to traditional separation science coupled with ...

Strategic Design of Public Food Procurement to Leverage Positive Food Systems Outcomes: A Framework of Actions

Sustainable Development, EarlyView.
ABSTRACT There is substantial potential for the procurement of food by public institutions to contribute to Sustainable Development across multiple environmental, social, and economic outcomes. In this study we used theories of policy instrumentation and learning to analyse global guidance for designing public food procurement instruments to leverage ...

Commuting Separately Quasihomogeneous Small Hankel Operators on Pluriharmonic Bergman Space

Journal of Function Spaces, 2018
We study (semi)commutativity of small Hankel operators with separately quasihomogeneous symbols on the pluriharmonic Bergman space of the unit ball. Some product problems are also concerned.

Pitardia resurrected: A new member of subtribe Menthinae (Lamiaceae)

TAXON, EarlyView.
Abstract Despite tremendous progress towards clarifying phylogenetic relationships within the mint family (Lamiaceae), uncertainty remains regarding relationships among some major clades as well as the proper placement of some genera. While researching the genus Nepeta, a species from northeastern Morocco, N.
