in this paper, a certain new connectedness of l-fuzzy subsets inl-topological spaces is introduced and studied by means of preclosed sets. itpreserves some fundamental properties of connected set in general topology.especially the famous k. fan’s theorem holds.

in this paper, we introduce λκ−closed sets and study its properties in generalized topological spaces.

In 5G ultradense heterogeneous networks, wireless backhaul, as one of the important base station (BS) resources that affect user services, has attracted more and attention. However, a would access to BS which is nearest for based on conventional association scheme, constrains network performance improvement due limited backhaul capacity. this paper, using backhaul-aware semiclosed expressions m...

In this article, we have shown, for the add-point monad T, thepartial morphism category Set*is isomorphic to the Kleisli category SetT. Alsowe have proved that the category, SetT, of T-algebras is isomorphic to thecategory Set of pointed sets. Finally we have established commutative squaresinvolving these categories.

a necessary and sufficient condition in terms of lower cut sets are given for the insertion of a $gamma-$continuous function between two comparable real-valued functions.

This study investigated the mechanism, prevention measures, and control methods for earthquake disasters typically occurring in mines with thick hard rock strata. A mine stope large faults strata Hebei Province was taken as background object. Then, theoretical analysis numerical simulation were adopted conjunction field monitoring to explore how horizontal stress evolves hanging roofs of such m...
