Neuroplasticity and MRI: A perfect match [PDF]

open access: yesNeuroImage, 2016
Numerous studies have illustrated the benefits of physical workout and cognitive exercise on brain function and structure and, more importantly, on decelerating cognitive decline in old age and promoting functional rehabilitation following injury. Despite these behavioral observations, the exact mechanisms underlying these neuroplastic phenomena remain

Erdős matching conjecture for almost perfect matchings

open access: yesDiscrete Mathematics, 2023
In 1965 Erdős asked, what is the largest size of a family of $k$-element subsets of an $n$-element set that does not have a matching of size $s+1$? In this note, we improve upon a recent result of Frankl and resolve this problem for $s>101k^{3}$ and $(s+1)k\le n<(s+1)(k+\frac{1}{100k})$.

哈林图的偶匹配可扩性(Bipartite matching-extendability of Halin graphs)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2009
Let G be a connected graph containing a perfect matching. G is said to be bipartite matching extendable if every matching M of G whose induced subgraph is a bipartite matching extends to a perfect matching of G. The main result is as follows: Halin graph

Two short proofs of the Perfect Forest Theorem

open access: yesTheory and Applications of Graphs, 2017
A perfect forest is a spanning forest of a connected graph $G$, all of whose components are induced subgraphs of $G$ and such that all vertices have odd degree in the forest.

A note on pm-compact bipartite graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2014
A graph is called perfect matching compact (briefly, PM-compact), if its perfect matching graph is complete. Matching-covered PM-compact bipartite graphs have been characterized. In this paper, we show that any PM-compact bipartite graph G with δ (G) ≥ 2

Exploration of CPCD number for power graph

open access: yesمجلة بغداد للعلوم, 2023
Recently, complementary perfect corona domination in graphs was introduced. A dominating set S of a graph G is said to be a complementary perfect corona dominating set (CPCD – set) if each vertex in  is either a pendent vertex or a support vertex and ...

On the number of perfect matchings in random polygonal chains

open access: yesOpen Mathematics, 2023
Let GG be a graph. A perfect matching of GG is a regular spanning subgraph of degree one. Enumeration of perfect matchings of a (molecule) graph is interest in chemistry, physics, and mathematics.

Conditional Strong Matching Preclusion of the Alternating Group Graph

open access: yesTheory and Applications of Graphs, 2019
The strong matching preclusion number of a graph is the minimum number of vertices and edges whose deletion results in a graph that has neither perfect matchings nor almost-perfect matchings.
