MUCH has been written in recent years about the cause and origin of Pink Disease (Erythrodema Polyneuritica). It is only within the last twenty years that the condition has been recognised. It was thought to be a nutritional disorder due to lack of vitamin B, a variation of this being that it was due to lack of absorption of vitamin B. Later it was thought to be due to a virus and to have a sli...

We show that several versions of Floyd and Rivest’s algorithm Select [Comm. ACM 18 (1975) 173] for finding the kth smallest of n elements require at most n+min{k, n − k}+ o(n) comparisons on average, even when equal elements occur. This parallels our recent analysis of another variant due to Floyd and Rivest [Comm. ACM 18 (1975) 165–172]. Our computational results suggest that both variants per...

We prove that when a countable group admits a nontrivial Floyd-type boundary, then every nonelementary and metrically proper subgroup contains a noncommutative free subgroup. This generalizes the corresponding well-known results for hyperbolic groups and groups with infinitely many ends. It also shows that no finitely generated amenable group admits a nontrivial boundary of this type. This impr...

Since the now-famous storm of September 1999, the name "Floyd" has taken on new associations for many people in eastern North Carolina: devastation and environmental catastrophe. On 12 November 1999, representatives from state and federal agencies and local universities met on the NIEHS campus in Research Triangle Park, North Carolina, to discuss the environmental health implications of the flo...

Review of Floyd Collins, Seamus Heaney: The Crisis Identity (Newark: University Delaware Press, 2003)

The binuclear iron cluster of uteroferrin in its reduced and enzymatically active pink form is sensitive to a variety or perturbants. Orthophosphate, in the presence or absence of oxygen, rapidly shifts the absorption maximum of pink uteroferrin from 510 to 545 nm, concurrently abolishing the protein's g'av = 1.74 EPR signal. Apparently, therefore, dioxygen is not required for phosphate-induced...
