The mayfly nymph Austrophlebioides pusillus Harker defies common osmoregulatory assumptions

Osmoregulation is a key physiological function, critical for homeostasis. The basic physiological mechanisms of osmoregulation are thought to be well established. However, through a series of experiments exposing the freshwater mayfly nymph Austrophlebioides pusillus (Ephemeroptera) to increasing salinities, we present research that challenges the extent of current understanding of the relation...

Evaluating Harker and O'Leary's distance approximation for ellipse fitting

Harker and O’Leary’s [3] recently proposed a new distance measure for conics. This paper compares its accuracy and effectiveness against several other error of fits (EOFs) for ellipses using: 1/ visualisations of the distortions with respect to the Euclidean distance; 2/ a set of evaluation measures specifically designed for assessing ellipse EOFs [7, 8]; 3/ the accuracy of LMedS ellipse fittin...

Research Interest:-Cancer Biology The goal of our research effort is to understand the biology of cancer cells. From an understanding of the defects in a cancer cell, rational strategies for treatment can be developed.

David Smyth

David Smyth is a plant developmental geneticist. He began his independent career at Monash University in Melbourne in 1974, where he investigated the basis of the very large genomes of the true lilies (Lilium species) when DNA cloning methods became available. Two abundant dispersed elements turned out to be retrotransposons, revealing their important role in bulking up some plant genomes. In 1...
