A Hybrid Method for Complex Pythagorean Fuzzy Decision Making
Mathematical Problems in Engineering, Volume 2021, Issue 1, 2021., 2021 This article takes advantage of advancements in two different fields in order to produce a novel decision‐making framework. First, we contribute to the theory of aggregation operators, which are mappings that combine large amounts of data into more advantageous forms.

Generating Second Order (Co)homological Information within AT-Model Context [PDF]
, 2019 In this paper we design a new family of relations between (co)homology classes, working with coefficients in a field and starting from an AT-model (Algebraic Topological Model) AT(C) of a finite cell complex C These relations are induced by elementary

The largest component of faulty star graphs
Theoretical Computer Science, 2020 The minimum size of the largest component of a network with faults is a useful parameter to make a full evaluation of this network and it is helpful for estimating some other parameters in graph theory.

Journal of Neuroendocrinology, Volume 32, Issue 12, December 2020., 2020 Rodent studies suggest that consumption of a high‐fat high‐sugar diet impacts on the brain's dopaminergic system. Should the same hold for humans, a diet high in saturated fat and added sugar should impact on dopamine‐mediated cognition. Here we show that acute peripheral dopamine precursor depletion impacts differently on working memory performance in

Algebraic matroids with graph symmetry [PDF]
, 2013 This paper studies the properties of two kinds of matroids: (a) algebraic matroids and (b) finite and infinite matroids whose ground set have some canonical symmetry, for example row and column symmetry and transposition symmetry.

Are Elephants Bigger than Butterflies? Reasoning about Sizes of Objects
, 2016 Human vision greatly benefits from the information about sizes of objects. The role of size in several visual reasoning tasks has been thoroughly explored in human perception and cognition. However, the impact of the information about sizes of objects is

The visual boundary of hyperbolic free-by-cyclic groups
, 2018 Let $\phi$ be an atoroidal outer automorphism of the free group $F_n$. We study the Gromov boundary of the hyperbolic group $G_{\phi} = F_n \rtimes_{\phi} \mathbb{Z}$. We explicitly describe a family of embeddings of the complete bipartite graph $K_{3,3}$

2-Vertex Connectivity in Directed Graphs
, 2015 We complement our study of 2-connectivity in directed graphs, by considering the computation of the following 2-vertex-connectivity relations: We say that two vertices v and w are 2-vertex-connected if there are two internally vertex-disjoint paths from ...

Degree-3 Treewidth Sparsifiers [PDF]
, 2014 We study treewidth sparsifiers. Informally, given a graph $G$ of treewidth $k$, a treewidth sparsifier $H$ is a minor of $G$, whose treewidth is close to $k$, $|V(H)|$ is small, and the maximum vertex degree in $H$ is bounded.
