It is known that if a 2-universal hash function H is applied to elements of a block source (X1, . . . , XT ), where each item Xi has enough min-entropy conditioned on the previous items, then the output distribution (H,H(X1), . . . , H(XT )) will be “close” to the uniform distribution. We provide improved bounds on how much min-entropy per item is required for this to hold, both when we ask tha...

Peritoneal closure is a controversial issue among obstetricians and gynaecologists. This article reappraises the issue of peritoneal closure. We conducted a thorough literature search using Medline, Pubmed and Embase as well as a hand-search for all references quoted in the relevant papers. The routine non-closure of the peritoneum reduces operation time by an average of 6 min. Most studies sho...
