Stealth navigation is a fundamental capability for a scout vehicle to e ectively perform reconnaissance missions. One component of stealth is the ability to plan paths that minimize visibility of the vehicle from target locations. This paper demonstrates a stealth planning system using visibility analysis on digital terrain elevation maps for path planning. Goal locations can be user speci ed o...

There are a variety of bacterial defense strategies to survive in a hostile environment. Generation of extracellular polysaccharides has proved to be a simple but effective strategy against the host's innate immune system. A comparative genomics approach led us to identify a new protein family termed Stealth, most likely involved in the synthesis of extracellular polysaccharides. This protein f...

Stealth assessment provides an innovative way to assess and ultimately support knowledge, skills, and other personal attributes within learning or gaming environments without disrupting students’ flow. In this paper, we briefly discuss two challenges we encountered during the development of stealth assessments in two past projects (i.e., utility issues related to log files and validation issues...

BACKGROUND We have previously found that Wnt signaling is activated in mesothelioma cells. To clarify the effect of blocking Wnt signaling in mesothelioma, the expression of dishevelled (Dvl), an intermediator of Wnt signaling, was down-regulated by a reformed type of small interfering RNA (siRNA), stealth RNAi, which can reduce the cytotoxic interferon response unlike conventional siRNA. MAT...

Article history: Received 13 August 2012 Received in revised form 31 December 2013 Accepted 16 January 2014 Available online 23 January 2014 Companies can increase executive compensation by allowing dividends to be paid on unvested restricted stocks grants, also known as stealth compensation. Examining all S&P 500 firms over the period 2003–2007, we find that more than half of the dividend payi...

Various liposomal drug carriers have been developed to overcome short plasma half-life and toxicity related side effects of chemotherapeutic agents. We developed a mathematical model to compare different liposome formulations of doxorubicin (DOX): conventional chemotherapy (Free-DOX), Stealth liposomes (Stealth-DOX), temperature sensitive liposomes (TSL) with intra-vascular triggered release (T...

Stealth assessment represents a promising way to address the needs of validly measuring and supporting important 21st century competencies (e.g., creativity, problem solving) within interactive digital environments (e.g., video games). The assessment is woven into the environment such that it becomes invisible to students, which is conducive to eliciting targeted competencies (Shute, 2011). Ste...
