One of the most compelling social questions, which until now was left unanswered by current technology, is "Who's that?" This question is usually asked about a new unfamiliar person in a social setting who piques your curiosity. This article presents WhozThat, a system that ties together online social networks with mobile smart- phones to answer this common(More)
Group recommendation, which makes recommendations to a group of users instead of individuals, has become increasingly important in both the workspace and people's social activities, such as brainstorming sessions for coworkers and social TV for family members or friends. Group recommendation is a challenging problem due to the dynamics of group memberships(More)
Social network information is now being used in ways for which it may have not been originally intended. In particular , increased use of smartphones capable of running applications which access social network information enable applications to be aware of a user's position and preferences. However, current models for exchange of this information require(More)
The in vitro toxicity of multiple hydrophobic compounds was the focus of this study. A mitochondrial respiratory assay, sensitive to perturbations caused by hydrophobic chemicals, was utilized to measure the effects of individual aromatic hydrocarbon pollutants and their mixtures on mitochondrial respiratory function. Benzene, naphthalene, acenaphthene, and(More)

The bacteriophage population is large, dynamic, ancient, and genetically diverse. Limited genomic information shows that phage genomes are mosaic, and the genetic architecture of phage populations remains ill-defined. To understand the population structure of phages infecting a single host strain, we isolated, sequenced, and compared 627 phages of(More)
The bioactivation of cyclopenta[cd]pyrene (CPP) was investigated to determine the major DNA adduct-forming metabolite(s) of this widespread environmental contaminant and suspect carcinogen. DNA adducts were analyzed by 32P-postlabeling. Four major and at least seven minor adducts formed when CPP was incubated with calf thymus DNA in the presence of rat(More)
Traffic anomalies and distributed attacks are commonplace in today's networks. Single point detection is often insufficient to determine the causes, patterns and prevalence of such events. Most existing distributed intrusion detection systems (DIDS) rely on centralized fusion, or distributed fusion with unscalable communication mechanisms. In this paper, we(More)
This paper presents a vision of mobile-cloud computing systems which looks beyond simply moving data processing from mobile to cloud computing systems and considers a larger vision in which services within the cloud are aggre-gated and automatically integrated in real-time, based on context, to satisfy the intentions of mobile computing applications. We(More)
