Recursive algorithms for symmetric indeenite linear systems are considered in the present paper. First, the diiculties with the recur-sive formulation of the LAPACK SYSV algorithm (which implements the Bunch-Kaufman pivoting strategy) are discussed. Then a recursive perturbation based algorithm is proposed and tested. The experiments show that the new algorithm can be about two times faster alt...

Although the levels of LDH have been estimated in the aqueous humour of animals (Kuhlman, and Kaufman, I960), information regarding LDH levels in human aqueous humour appears to be scanty. It is known that malignant tumours at different sites in the body are associated with an increased LDH activity in the corresponding body fluid (Wroblewski, 1957). The purpose of the present study is to deter...

On a spring evening two years ago, Steve Kaufman, a wiry 18-yearold whose plain-featured intensity reminds one of Dustin Hoffman, hurried across the Stanford University campus to what he thought would be an interesting and enjoyable experience. He was headed for Jordan Hall, where the department of psychology is housed and where he had been receiving training as a hypnotic subject, preparatory ...

The agINFRA project focuses on the production of interoperable data in agriculture, starting from the vocabularies and KOS used to classify and annotate them. In this paper we report on our first steps in the direction of contributing to a LOD of agricultural data. In particular we look at germplasm data and soil data, which are still widely missing from the LOD landscape, seemingly because inf...

Paediatricians at the Lady Cilento Hospital in Brisbane are now entering the sixth day of their protest against the Australian government’s intention to send the young baby of asylum seeker parents back to a refugee detention centre on the Pacific island of Nauru. They believe that the centre cannot provide a safe environment for her, an assertion that is backed by ample evidence. 3 These docto...
