On certain estimates for marcinkiewicz integrals and extrapolation
(
Universidad de Barcelona
, 2009 , Article)
We obtain Lp estimates for parametric Marcinkiewicz integrals associated to polynomial mappings and with rough kernels on the unit sphere as well as on the radial direction. These estimates will allow us to use an extrapolation ...
Boundedness of rough integral operators on triebel-lizorkin spaces
(
Universitat Autonoma de Barcelona, Seccio de Matematiques
, 2012 , Article)
We prove the boundedness of several classes of rough integral operators on Triebel-Lizorkin spaces. Our results represent improvements as well as natural extensions of many previously known results.

Towards a ‘democratic knowledge’ turn? Knowledge production in the age of the Arab Spring
(
Taylor & Francis
, 2015 , Article)
This contribution (and the special issue as a whole) marks a modest attempt to initiate an investigation into what is called here ‘democratic knowledge’. This is done with special reference to the Arab Maghrib (in this ...
Insights into the interaction between mineral formation and heavy metals immobilization, mediated by Virgibacillus exopolymeric substances
(
Elsevier
, 2024 , Article)
Heavy metal pollution poses significant risks to both the environment and human health due to their toxicity, long residence times, and their ability to bioaccumulate and bio magnify across the food chain. To address this ...
An efficient image encryption scheme based on fractal Tromino and Chebyshev polynomial
(
Springer International Publishing
, 2021 , Article)
The security of digital content during transmission and storage through insecure communication links and databases is a challenging issue in today's world. In this article, an encryption scheme based on fractal Tromino and ...
A Class of Koszul Algebra and Some Homological Invariants through Circulant Matrices and Cycles
(
Hindawi Limited
, 2022 , Article)
Recent advances in graph theory, linear algebra, and commutative algebra render us to tackle problems in one bough of mathematics with assistance and guidance from others. We will elaborate foremost and conceptually ...
Polycircular domains, numerical conformal mappings, and moduli of quadrilaterals
(
Springer Nature
, 2022 , Article)
We study numerical conformal mappings of planar Jordan domains with boundaries consisting of finitely many circular arcs, also called polycircular domains, and compute the moduli of quadrilaterals for these domains. ...
Ion-impact-induced interatomic Coulombic decay in neon and argon dimers
(
American Physical Society
, 2013 , Article)
We investigate the contribution of interatomic Coulombic decay induced by ion impact in neon and argon dimers (Ne2 and Ar2) to the production of low-energy electrons. Our experiments cover a broad range of perturbation ...
Finding the Nearest Negative Imaginary System with Application to Near-Optimal Controller Design
(
Institute of Electrical and Electronics Engineers Inc.
, 2023 , Conference Paper)
In this paper, we consider the problem of robust stabilization of linear time-invariant systems with respect to unmodeled dynamics and structure uncertainties. To that end, we first present a methodology to find the nearest ...
