Effects on working memory performance relating to item similarity have been linked to prior categorisation of representations in long-term memory. However, there is evidence from gesture processing that this link may not be obligatory. The present study investigated whether working memory for incidentally generated meaningless manual gestures is influenced by formational similarity and whether ...

Shape-based retrieval of vertebral x-ray images is a challenging task because of high similarity among the vertebral shapes. Most techniques, such as global shape properties or scale space filtering, lose or fail to detect local details. As the result of this shortfall, the number of retrieved images is so high that the retrieval result is sometimes meaningless. To retrieve a small number of be...

I n the early 1970s, when recombinant DNA technology became available, scientists exercised a healthy amount of caution. Within just a few years, as effective laboratory safety rules were established, it became clear that DNA recombinant organisms posed no greater risk than any other biotechnology, including particularly agricultural biotechnology. This evident lack of special risk is what has ...
