Searching on remote encrypted data (commonly known as searchable en-cryption) has become an important issue in secure data outsourcing, since it allows users to outsource encrypted data to an untrusted third party while maintains the capability of keyword search on the data. Searchable encryption can be achieved using the classical method called oblivious(More)
Schizophrenia (SCZ) is a severe psychiatric disorder associated with many different risk factors, both genetic and environmental. A recent genome-wide association study (GWAS) of Han Chinese identified three single-nucleotide polymorphisms (SNPs rs11038167, rs11038172, and rs835784) in the tetraspanins gene TSPAN18 as possible susceptibility loci for(More)
—Delay Tolerant Networks (DTNs) are intermittently connected networks, such as mobile social networks formed by human-carried mobile devices. Routing in such mobile social DTNs is very challenging as it must handle network partitioning , long delays, and dynamic topology. Recently, social-based approaches, which attempt to exploit social behaviors of DTN(More)
Robustness and reliability with respect to the successful completion of a schedule are crucial requirements for scheduling in multi-agent systems because agent autonomy makes execution environments dynamic and nondeterministic. We introduce a model to incorporate trust which indicates the probability that an agent will comply with its commitments into(More)
This paper presents the ARTS (Agent-oriented Robust Transactional System) model, which applies transaction concepts to provide agent developers with high-level support for agent system robustness and reliability. ARTS abstractly considers agents as executors of encapsulated task entities which comply with a set of execution constraints on both normative(More)
Commitment-modeled protocols enable flexible and robust interactions among agents. However, existing work has focused on features and capabilities of protocols without considering the active role of agents in them. Therefore, in this paper we propose to augment agents with the ability of reasoning about and manipulating their commitments to maximize the(More)
Coalition formation in social networks consisting of a graph of interdependent agents allows many choices of which task to select and with whom to partner in the social network. Agents communicate with agents within n network links in their surrounding network. These agents are considered part of an agent's local neighborhood. Agents maintain a database of(More)
