Matkowski-Type Functional Contractions under Locally Transitive Binary Relations and Applications to Singular Fractional Differential Equations

open access: yesFractal and Fractional
This article presents a few fixed-point results under Matkowski-type functional contractive mapping using locally J-transitive binary relations. Our results strengthen, enhance, and consolidate numerous existent fixed-point results.

Aggregating Fuzzy Binary Relations and Fuzzy Filters

open access: yesDiscussiones Mathematicae - General Algebra and Applications, 2018
The main goal of this paper is to investigate the aggregation of diverse families of binary fuzzy relations, fuzzy filters, and fuzzy lattices. Some links between these families and their images via an aggregation are explored.

Postoptimal analysis of one lexicographic combinatorial problem with non-linear criteria [PDF]

open access: yesComputer Science Journal of Moldova, 2009
In this article we consider a multicriteria combinatorial problem with ordered MINMIN criteria. We obtain necessary and sufficient conditions of that type of stability to the initial data perturbations for which all lexicographic optima of the original ...

Interpretation of RNA Universe and Coding Potential Using IntRNA

open access: yesAdvanced Science, EarlyView.
This study constructs a multi‐channel deep learning framework IntRNA to interpret RNA universe and coding potential. IntRNA consistently performed the best among existing methods in various benchmarks. Moreover, IntRNA’s interpretability is also validated by real‐world analysis, which found some features indicating long‐distance contact between ...

On the Structure of Acyclic Binary Relations

open access: yes, 2018
We investigate the structure of acyclic binary relations from different points of view. On the one hand, given a nonempty set we study real-valued bivariate maps that satisfy suitable functional equations, in a way that their associated binary relation is acyclic. On the other hand, we consider acyclic directed graphs as well as their representation by
