Modelling disease dynamics is most useful when data are limited. We present a spatial transmission model for the spread of canine rabies in the currently rabies-free wild dog population of Australia. The introduction of a sub-clinically infected dog from Indonesia is a distinct possibility, as is the spillover infection of wild dogs. Ranges for parameters were estimated from the literature and ...

In this paper, a novel watermarking method in the Difference of Gaussian (DoG) Scale Space is proposed. The idea is to decompose image into DoG scales and insert the watermark into these DoG sub-images using a multiscale JND (Just Noticeable Difference) model, providing an invisible and robust watermarking scheme. In order to survive de-synchronization attacks, we use the SIFT (Scale Invariant ...

The unique breeding structure of the domestic dog makes canine genetics a useful tool to further the understanding of inherited diseases and gene function. Answers to the questions of when and where the dog was domesticated from the wolf are uncertain, but how the modern diversity of dog breeds was developed is documented. Breed development has resulted in many genetically isolated populations ...

Young children (less than 11 years old) are a particular risk group for dog bites. Dog bites commonly occur from the family pet. Alsatian or alsatian mixes are the biggest group in the study causing dog bites. Alsations are a popular breed. By comparison Retrievers (Labrador and Golden), also a popular breed, caused few bites.

Conventional Difference of Gaussian (DOG) filter is usually used to model the early stage of visual processing. However, convolution operation used with DOG does not explicitly account for the effects of disinhibition. Because of this, complex brightness-contrast (B-C) illusions such as the White’s effect cannot be explained using DOG filters. We discovered that a model based on lateral disinhi...
