On the number of matchings of a tree
The author obtains explicit expressions for the average number of \(k\)-matchings and the average number of maximal matchings of size \(k\) in rooted ordered trees, labelled trees, and \(s\)-ary trees with \(n\) vertices; and he derives asymptotic expressions for the average total number of maximum matchings in rooted ordered trees, labelled trees, and

Fractional matching preclusion for generalized augmented cubes [PDF]
The \emph{matching preclusion number} of a graph is the minimum number of edges whose deletion results in a graph that has neither perfect matchings nor almost perfect matchings.

Estimating the number of principal components via Split-Half Eigenvector Matching (SHEM)
Estimating the number of principal components to retain for dimension reduction is a critical step in many applications of principal component analysis. Common methods may not be optimal, however.

ABSTRACT Background Loneliness is associated with adverse physical and mental health outcomes and remains understudied in children and adolescents undergoing cancer therapy. Pediatric oncology patients may be at increased risk due to medical isolation and disruption of social networks.

Clique descriptor of affine invariant regions for robust wide baseline image matching [PDF]
Assuming that the image distortion between corresponding regions of a stereo pair of images with wide baseline can be approximated as an affine transformation if the regions are reasonably small, recent image matching algorithms have focused on affine ...

ABSTRACT Background Children with sickle cell anemia (SCA) in low‐income settings are at risk of severe malnutrition, but optimal nutritional management has not been established. We evaluated an intensified ready‐to‐use therapeutic food (RUTF) regimen in children with persistent severe malnutrition after initial treatment and assessed whether early ...

ABSTRACT Rates of cancer among adolescents and young adults (AYA), age 15–39 years, are increasing. Consequently, radiation oncologists are treating more AYAs who have diagnoses spanning both pediatric and adult practices. Compared to pediatric and older adult patients, AYAs face a unique set of challenges.
