Liposomes are used as a delivery vehicle for drug molecules and imaging agents. The major impetus in their biomedical applications comes from the ability to prolong their circulation half-life after administration. Conventional liposomes are easily recognized by the mononuclear phagocyte system and are rapidly cleared from the blood stream. Modification of the liposomal surface with hydrophilic...

Stealth game mechanics rely on a suitably difficult distribution of enemy observers, the placement of which is typically a manual process. Here we investigate an automatic process for placement of observer opponents. We use a Monte-Carlo approach to generate randomized enemy positions and motions and combine this with a stealth path-planning and analysis framework. This allows us to ensure feas...

In order to effectively evade anti-malware solutions, Android malware authors are progressively resorting to automatic obfuscation strategies. Recent works have shown, on small-scale experiments, the possibility of evading anti-malware engines by applying simple obfuscation transformations on previously detected malware samples. In this paper, we provide a large-scale experiment in which the de...

We used stealth assessment, embedded in a game called Use Your Brainz (a slightly modified version of Plants vs. Zombies 2), to measure middle-school students’ problem solving skills. We began by developing a problem solving competency model based on a review of the relevant literature. We then identified ingame indicators that would provide evidence about students’ levels on various problem-so...

The extent to which opportunities afforded by e-learning are embraced by an institution can depend in large measure on whether it is perceived as enabling and transformative or as a major and disruptive distraction. Most case studies focus on the former. This paper describes how e-learning was introduced into the latter environment. The sensitivity of competing pressures in a research intensive...

The apparent association of Zika virus infection with microcephaly appears to be largely confined to Brazil. While this could be due to genetic changes in the Brazilian Zika virus, it is also consistent with a facilitating effect of co-infection with another virus. Public health authorities have been reluctant to acknowledge the presence of stealth adapted viruses [1]. These viruses have deleti...
