1. Visual abilities decline during normal aging, and many of these declines are due to neural changes in the retina or central visual pathways. We have begun studies of the primate visual system to investigate the location and nature of these changes as well as to answer general questions about the effects of aging on neural function. We began with the(More)
The probability-distributed principle in basin-scale hydrology considers the frequency of occurrence of hydrological variables (model inputs, parameters or elements) of certain magnitudes over the basin without regard to the location of a particular occurrence within the basin. The random assemblage of different parts is considered more important than the(More)

This paper reports the trial of a wearable data capture device, SenseCam, as a resource for digital narratives and uses data from the trial to reflect on the models of the 'mind' that underscore HCI. More particularly, over a period of one week, 5 participants and 2 researchers used SenseCams to capture digital traces of their experiences, and used the same(More)
The present experiments examined the extent to which binocular processing in the cat's dorsal lateral geniculate nucleus (LGN) depends upon the spatial frequency, orientation, and direction of movement of stimuli presented to the nondominant eye. In Experiment 1, we tested the effects of varying these stimulus parameters on the responses of LGN cells to(More)
Intermittent streamflow is a common occurrence in permeable catchments, especially where there are pumped abstractions to water supply. Many rainfall-runoff models are not formulated so as to represent ephemeral streamflow behaviour or to allow for the possibility of negative recharge arising from groundwater pumping. A groundwater model component is(More)
Outcome prediction is becoming increasingly important in medicine, but when a resource is scarce the need for accurate prediction becomes acute. Prediction based on biostatistical models has been in use for many years, but in areas such as renal transplantation their results have been disappointing. Recently however, there has been growing interest in the(More)
This paper reports the trial of a memory prosthesis, SenseCam, as a resource for digital narratives. Over a period of one week, six participants were asked to use SenseCams to capture digital traces of their experiences, and to use the same to create 'story telling' materials for presentation. The study found that all users delighted in the devices, though(More)
