Abstract To understand genome evolution in a group of microbes, we need to know the timing of events such as duplications, deletions and horizontal transfers. A common approach is to perform a gene-tree / species-tree reconciliation. While a number of software packages perform this type of analysis, none are geared toward a complete reconstruction for all families in an entire clade. Here we describe an update to the xenoGI software package which allows users to perform such an analysis using the newly developed DTLOR (duplication-transfer-loss-origin-rearrangement) reconciliation model starting from genome sequences as input.more » « less

This work proposes the development of a robot to perform appropriate tasks to assist low income older adults based on the merging of two previous studies, one which focused on task investigation and deployment of mobile robots in elder care facilities and the other on design investigation for a socially assistive robot using low-cost and modular hardware and software design. We identified that hydration, walking and socialization were tasks appropriate for the robot and most impactful to the older adults. Another outcome was the level of importance of the HRI component in the implementation of these tasks, thus merging both studies to initially investigate preferences in service robots for elder care is proposed.more » « less

In this paper a novel telescopic manipulator was adapted to a mobile robotic base to perform manipulation tasks in an elder care facility. As indicated by our previous work, leisure activities and engagement in socialization were desirable among elders, and a physical game assisted by the robot was chosen to investigate both its acceptance and interaction with the older adults. The robot was deployed at an assisted living center and performed multiple interactions. The manipulator was able to successfully retrieve items from different heights as part of the game and results from post-interaction surveys with elders indicated high perceived usefulness and comfort in having the robot as an assistant in the game.more » « less
