Let [n]={1,2,…,n}[n]=\{1,2,\ldots,n\} and Bn={A:A?[n]}\mathscr{B}_n=\{A: A\subseteq [n]\}. A family A?Bn\mathscr{A}\subseteq \mathscr{B}_n is a Sperner family if A?A\nsubseteq B and B\nsubseteq AB\nsubseteq A for distinct A,B\in\mathscr{A}A,B\in\math... see more

Subdivision schemes are famous for the generation of smooth curves and surfaces in CAGD (Computer Aided Geometric Design). The continuity is an important property of subdivision schemes. Subdivision schemes having high continuity are always required for g... see more

A class of distribution-free tests based on convex combination of two U-statistics is considered for testing independence against positive quadrant dependence. The class of tests proposed by Kochar and Gupta (1987) and Kendall’s test are members of the pr... see more

A new species of green paleosiphonoclad?l algae Kamaena gigantea from the Lower–lowermost Middle Mississippian sediments of the Donbas has been described. This species was distinguished from other representatives of the genus Kamaena Antropov by its extre... see more

Introduction; quizzes are needed to increase student motivation to learn and assess their understanding of the course material. Quizzes can take the form of conventional tests (paper-based tests) and can use information technology, for example, the "Kahoo... see more

In this paper, we define and investigate a subclass of univalent harmonic functions defined by Salagean integral operator with respect to symmetric points. We obtain coefficient conditions, extreme points, distortion bounds, convex combinations for this f... see more

This paper focuses on the problem of delay dependent stability/stabilization of interconnected systems with time-varying delays. The approach is based on a new Lyapunov-Krasovskii functional. A decentralized delay-dependent stability analysis is performed... see more
