Background: During lactation, metabolic changes in the bone in different areas of the body may affect the amount of bone mineral density.The aim of this study was to determine the relationship between breastfeeding and bone mineral density in women. Materials and Methods:  In this study, articles were searched at Cochran, Medline (via PubMed), Scopus, and Web of Science databases until June 201...

let $mathfrak{f}$ be a formation and $g$ a finite group. a subgroup $h$ of $g$ is said to be weakly $mathfrak{f}_{s}$-quasinormal in $g$ if $g$ has an $s$-quasinormal subgroup $t$ such that $ht$ is $s$-quasinormal in $g$ and $(hcap t)h_{g}/h_{g}leq z_{mathfrak{f}}(g/h_{g})$, where $z_{mathfrak{f}}(g/h_{g})$ denotes the $mathfrak{f}$-hypercenter of $g/h_{g}$. in this paper, we study the structur...

I am surprised by the published conclusions of Hung et al 1 in a recent issue of CHEST (August 2013). The authors’ stated meth ods are not adequate to support their conclusion that hyperimmune IV immunoglobulin (H-IVIG) ben efi ts mortality if given within 5 days to patients with severe 2009 infl uenza A(H1N1) infection. The primary outcome analysis of 34 patients presented in Table 1 of the st...

This paper summarizes the subgroup discovery method SUBARP. The discussion is to provide an intuitive understanding of the ideas underlying the method, and mathematical details are omitted.

Subgroup discovery is a popular form of supervised rule learning, applicable to descriptive and predictive tasks. In this work we study two natural extensions of classical subgroup discovery to distributed settings. In the first variant the goal is to efficiently identify global subgroups, i.e. the rules an analysis would yield after collecting all the data at a single central database. In cont...

In this paper we propose cryptosystems based on subgroup distortion in hyperbolic groups. We also include concrete examples of hyperbolic groups as possible platforms.
