New dynamic Hilbert-type inequalities in two independent variables involving Fenchel–Legendre transform

open access: yesAdvances in Difference Equations, 2021
In this paper, we establish some dynamic Hilbert-type inequalities in two independent variables on time scales by using the Fenchel–Legendre transform. We also apply our inequalities to discrete and continuous calculus to obtain some new inequalities as ...

Some Refinements of the Numerical Radius Inequalities via Young Inequality [PDF]

open access: yesKragujevac Journal of Mathematics, 2021
In this paper, we get an improvement of the Hölder-McCarthy operator inequality in the case when r ≥ 1 and refine generalized inequalities involving powers of the numerical radius for sums and products of Hilbert space operators.

Fractional order PDα-type ILC for linear continuous time-delay switched system with disturbance measurement and uncertainties noise [PDF]

open access: yesJournal of Hyperstructures
This study investigates the efficacy of a novel PDα-type fractional-order iterative learning control (FOILC) approach for a class of fractional-order linear continuous-time delaying switched systems.

Noncommutative Uncertainty Principles [PDF]

open access: yes, 2014
The classical uncertainty principles deal with functions on abelian groups. In this paper, we discuss the uncertainty principles for finite index subfactors which include the cases for finite groups and finite dimensional Kac algebras.

Gender inequality and sex differences in physical fighting, physical activity, and injury among adolescents across 36 countries [PDF]

open access: yes, 2019
Purpose: Sex differences in adolescent health are widely documented, but social explanations for these sex differences are scarce. This study examines whether societal gender inequality (i.e., men’s and women’s unequal share in political participation ...

Conceptualising quality early childhood education: Learning from young children in Brazil and South Africa through creative and play‐based methods

open access: yesBritish Educational Research Journal, EarlyView., 2023
Abstract Early childhood has increasingly been acknowledged as a vital time for all children. Inclusive and quality education is part of the United Nations Sustainable Development Goals, with the further specification that all children have access to quality pre‐primary education.

On further refinements for Young inequalities

open access: yesOpen Mathematics, 2018
In this paper sharp results on operator Young’s inequality are obtained. We first obtain sharp multiplicative refinements and reverses for the operator Young’s inequality.
