There has been much research into freeness properties of finitely generated matrix semigroups under various constraints, mainly related to the dimensions of the generator matrices and the semiring over which the matrices are defined. A recent paper has also investigated freeness properties of matrices within a bounded language of matrices, which are of the form M1M2 · · ·Mk ⊆ Fn×n for some semi...

BACKGROUND Splitting a liver for utilization in adult/pediatric recipients has been shown to decrease mortality on the wait list without increasing the overall risk of long-term graft failure compared to a whole graft. However, splitting a single donor organ for two adult recipients, full-right-full-left split liver transplantation (FRFLSLT), to overcome organ shortage is still considered contr...

The chronic shortage of deceased kidney donors has led to increased utilization of donation after cardiac death (DCD) kidneys, the majority of which are procured in a controlled setting. The objective of this study is to evaluate transplantation outcomes from uncontrolled DCD (uDCD) donors and evaluate their utility as a source of donor kidneys. From January 1995 to December 2004, 75,865 kidney...

A common strategy used to dismiss arguments against donor conception is that there is no proof donor-conceived persons are harmed in any important way. Their claims of harm are dismissed as anecdotal and "not scientific," and studies carried out on young donor-conceived children, who declare themselves perfectly happy with their parents and families are tendered as evidence that no harm is caus...

Introduction: Donor milk is a new emerging phenomenon in Iran and its banks are currently operating at a limited level. Nurses’ knowledge and attitudes toward this issue play a very important role in the adoption of human donor milk by families. The aim of this study was to determine the knowledge and attitude of nurses working in neonatal intensive care units   regarding the use of human donor...

In this note we prove only the important special case (1.1), omitting the parts of the argument required for other cases. In addition, we present an alternate proof, dating from 2002, of the lower bound implicit in (1.1). This proof avoids the use of results about uniform order statistics required in [3], and instead utilizes the cycle lemma from combinatorics. Although shorter and technically ...

This paper presents some central findings of an exploratory qualitative study of New Zealand families with children conceived by donor insemination (DI). Drawing on social anthropological and sociological theorising about kinship and contemporary Western families, the paper explores the ways in which parents and their kin actively construct parent-child relationships and kin connections through...
