Students Impression About Using Mobile Phones in Classroom
(
Kassel University Press GmbH
, 2020 , Article)
Mobile phones are widely used by university students and there is a controversial topic whether students should be able to use them freely during lectures. A survey was distributed seeking student opinions on using mobile ...
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.
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 ...
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 ...
Turning point in COVID-19 severity and fatality during the pandemic: a national cohort study in Qatar
(
BMJ Publishing Group
, 2023 , Article)
Objective To assess the evolution of COVID-19 severity and fatality in a unique setting that consistently applied, throughout the pandemic, rigorous and standardised criteria for defining severe COVID-19 outcomes.
Methods ...
Robust stabilization of LTI negative imaginary systems using the nearest negative imaginary controller
(
John Wiley and Sons Inc
, 2023 , Article)
This paper considers the problem of robust stabilization of linear time-invariant systems with respect to unmodelled dynamics and structure uncertainties. To that end, a methodology to find the nearest negative imaginary ...
On the boundedness of a class of rough maximal operators on product spaces
(2011 , Article)
In this paper, we study the Lp boundedness of a class of maximal operators T (γ) {Ωj} and a related class of rough singular integrals on product spaces. We obtain appropriate Lp estimates for such maximal operators and ...
History of primary-series and booster vaccination and protection against Omicron reinfection
(
American Association for the Advancement of Science
, 2023 , Article)
Laboratory evidence suggests a possibility of immune imprinting for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. We investigated the differences in the incidence of SARS-CoV-2 reinfection in a ...
