Alveolar regenerative gene expression is unidentified partly because its onset, after a regenerative stimulus, is unknown. Toward addressing this void, we used a mouse model in which calorie restriction produces alveolar loss, and ad libitum access to food after calorie restriction induces alveolar regeneration. We selected four processes (cell replication,(More)
— Robots that engage in social behaviors benefit greatly from possessing tools that allow them to manipulate the course of an interaction. Using a non-anthropomorphic social robot and a simple counting game, we examine the effects that empathy-generating robot dialogue has on participant performance across three conditions. In the self-directed condition,(More)
A molecular phylogeny was inferred for the 22 nominal species of black flies in the Simulium jenningsi species group, which includes major pests of humans and livestock in North America. Females are structurally monomorphic, presenting a problem for identification of the pests. For each species, we sequenced approximately two kilobases from the(More)
BACKGROUND Surgical management of the lower end of the ureter during laparoscopic nephroureterectomy remains a matter of debate. The commonest method during laparoscopic nephroureterectomy-endoscopic incision-has been shown to have a higher recurrence rate compared with open surgical excision with a cuff of bladder. In addition, the literature still lacks(More)
This project investigates the effects of gender in a human-robot collaboration interaction. In the experiment, participants completed four Sudoku-like puzzles with a robot from which they could verbally elicit help. The robot was given the gendered characteristics of a gendered computer generated voice and either the name Charlotte (female condition) or(More)
We present an opportunity for the visual sensing of depth and 3D velocity using a passive sensor that has extremely low power requirements. This opportunity comes from a new mathematical constraint, which we derive, that relates depth and velocity to spatial and temporal derivatives of image values captured by a coded-aperture camera that observes a moving(More)
