We consider maximal operators MBMB with respect to a basis BB. In the case when MBMB satisfies a reversed weak type inequality, we obtain a boundedness criterion for MBMB on an arbitrary quasi-Banach function space XX. B...

Abstract In the era of intelligent systems and data-driven technologies, making precise and reliable decisions under uncertainty has become increasingly vital. The primary aim of this study is to tackle decision making (...

Abstract The physical topology design (PTD) of optical networks is frequently accomplished by combining several solutions in an iterative way, especially if meta-heuristics are deployed for this purpose. Suitable operato...

In this paper, we investigate some properties of nonlinear integral operators of mixed type of integral equations with kernels depending on two variables. The results concerning the continuity and compactness of these op...

Weinvestigate some modal operators of necessity and possibility that form an adjoint pair in the context of meet-complemented lattices. We prove that they form an equational class and we study the modalities, i.e. the fi...

Abstract In this paper, we apply modified Bernstein operators B m ∗ ( f ) $B^{*}_{m}(f)$ to obtain the solution of Volterra integral equations of third type. We construct the numerical scheme, study the convergence ana...

In this work, we propose the rings of differential operators are simple and for this proposition we can generalize the results of Jones in 1995. In fact, this work is complement to the results of Mahmood in 2006.

The Federal Aviation Administration (FAA) has promulgated regulations to govern the commercial operation of small uncrewed aircraft systems (sUAS). Compliance with these regulations is essential for maintaining safety in...

The aim of this study is to examine the emotional effects of stimuli present in the work environment on employee behavior. The study utilized the stimulus-organism-response (SOR) model and included 182 operators from a d...

In this work we search for boundedness results for operators related to the semigroup generated by the degenerate Schrödinger operator Lu=−1ωdivA⋅∇u+Vu, where ω is a weight, A is a matrix depending on x and sati...

In this paper we give survey of hypercyclic composition operators. In pacticular,we represent new classes of hypercyclic composition operators on the spaces of analyticfunctions.

In this paper, left and right generalized Drazin invertible operators on Banach spaces are defined and characterized by means of the generalized Kato decomposition. Then, new binary relations associated with these operat...

Objectives: Rotating or night shifts elicit rapid changes in physiology which the body cannot quickly adapt. In addition, alterations in shift work influence social and familial aspects that ultimately impact the quality...

Abstract We reconsider in modern terms the old discovery by A. Kirillov and M. Noumi, who devised peculiar operators adding columns to Young diagrams enumerating the Schur, Jack and Macdonald polynomials. In this sense, ...

Commercial unmanned aircraft systems continue to increase in applications and diversity; however, mishaps and accidents erode safety, investment return, and efficiency. Most unmanned aircraft accidents are preceded by le...

Tunisia constitutes one of basic directions of tourist trips in Poland. However terrorist attack on the museum in Bardo, widely related in mass media, changed the image of Tunisia as the safe holiday destination. The ass...

Let μ be a nonnegative Borel measure on Rd satisfying that μ(Q) ⩽ l(Q)n for every cube Q ⊂ Rn, where l(Q) is the side length of the cube Q and 0 < n ⩽ d. We study the class of pairs of weights related to the boun...

We find necessary and sufficient conditions on a Banach space X in order for the vector-valued extensions of several operators associated to the Ornstein-Uhlenbeck semigroup to be of weak type (1,1) or strong type (p,p) ...

Scheduled air carrier aircraft operate at large and small commercial airports across the U.S. National Airspace System. These turbine-powered aircraft fly at high speeds during departure and approach, yet many commercial...

Abstract The gradient-flow formalism provides a framework for the direct determination of moments of parton distribution functions (PDFs) from lattice QCD calculations. Their conversion from the gradient-flow scheme to $...

The Handbook on Gender Equality, Equity, and Inclusion in Sports is an intellectual output of the Women in Sport: Gender Relations and Future Perspectives (Women-Up) project, co-funded by the European Union, This compreh...
