We developed a rapid, economical method for high-resolution quantitative trait locus (QTL) mapping using microarrays for selective genotyping of pooled DNA samples. We generated 21,207 F2 flies from two inbred Drosophila melanogaster strains with known QTLs affecting lifespan, and hybridized DNA pools of young and old flies to microarrays. We used changes(More)
Museums are increasingly embracing technologies that provide highly-individualized and highly-interactive experiences to visitors. With embodied interaction experiences, increased localization accuracy supports greater nuance in interaction design, but there is usually a tradeoff between fast, accurate tracking and the ability to preserve the identity of(More)
Despite the wide availability of body-sensing technologies, the design of control gestures that feel natural and that can be intuitively "guessed" by the users is still an embodied interaction challenge. This is especially true for systems that require a <i>set</i> of complementary control gestures. Part of the problem lies in the separation between the(More)
As data rather than physical artifacts become more commonly the product of modern scientific endeavor, we must attend to humandata interactions as people reason about and with representations of data increasingly being presented in museum settings. Complex data sets can be impenetrable for novices, so the exhibit presented here was designed to give visitors(More)
Patterns of suicide resilience vary considerably across ethnic groups and are an understudied dimension of suicide science. The purpose of the current study was to examine the relationship between cultural worldview and "reasons for living," an alternative index for suicide risk in a cross-cultural sample. The Reasons for Living Inventory and Worldview(More)
RFID is usually used for <i>identification</i> but with some post-processing it can also be used for <i>localization</i>. These properties expand the typical range of possible interactions with digital displays in museums. Our goal is to encourage the collaborative investigation of a rich information space presented on an Ambient Display in a museum(More)
The desorption of molecular species from ice mantles back into the gas phase in molecular clouds results from a variety of very poorly understood processes. We have investigated three mechanisms; desorption resulting from H 2 formation on grains, direct cosmic ray heating and cosmic ray induced photodesorption. Whilst qualitative differences exist between(More)
Many factors are known to mediate museum visitors' learning during their interactions with exhibits, including designed elements of the exhibit itself, the other visitors present in the space, and visitors' own backgrounds and prior knowledge. Research indicates that learners' use of a first-person <i>Actor</i> perspective may confer agency to the learner(More)
The "Uncanny Valley" theory explains the counter-intuitive phenomenon where people may get suddenly uncomfortable with an artificial entity when it becomes very similar to humans. We propose the existence of an "uncanny valley" for embodied interaction, when a user's body motions in the physical space (the locus of interaction) are incompletely mapped into(More)
The adaptation and use of advanced technologies is an effective and encouraging way to efficiently and reliably characterise crops and plants. Additionally advances in these technologies will improve the information available for agronomists, breeders and plant physiologists in order to develop best management practices in the process and commercialization(More)
