A procur...

Parallel computing on networks of workstations (NOWs) allows effective use of existing hardware and software. NOWs are often connected using a broadcast medium such as an Ethernet, so it is natural to use broadcast as a communication primitive. However, existing parallel programs usually rely on point-to-point protocols for performing broadcasts since native broadcast schemes (UDP broadcast) do...

Autism has been described as a disorder of general neural processing, but the particular processing characteristics that might be abnormal in autism have mostly remained obscure. Here, we present evidence of one such characteristic: poor evoked response reliability. We compared cortical response amplitude and reliability (consistency across trials) in visual, auditory, and somatosensory cortice...

As a result, the supply of and demand for aged care services has assumed increasing policy prominence. The likely spatial distribution of the need for aged care services is critical for planners and policy makers. This article describes ...
