In this paper, we present our approach of facilitator that allows automatic service composition in distributed systems. We propose a facilitator based on ontologies and knowledge representation that allows clients to discover a service and to get the result of the service execution without direct interactions with their providers. We extend the functionality of the facilitator to be a compositi...

Facilitators are oligonucleotides capable of affecting hammerhead ribozyme activity by interacting with the substrate at the termini of the ribozyme. Facilitator effects were determined in vitro using a system consisting of a ribozyme with 7 nucleotides in every stem sequence and two substrates with inverted facilitator binding sequences. The effects of 9mer and 12mer RNA as well as DNA facilit...

Within the university the introduction of computers is creating a new criterion of differentiation between those who as a matter of course become integrated in the technocratic trend deriving from the daily use of these machines and those who become isolated by not using them. This difference increases when computer science and communications merge to introduce virtual educational areas, where ...

Glycerol transport is commonly cited as the only example of facilitated diffusion across the Escherichia coli cytoplasmic membrane. Two proteins, the glycerol facilitator and glycerol kinase, are involved in the entry of external glycerol into cellular metabolism. The glycerol facilitator is thought to act as a carrier or to form a selective pore in the cytoplasmic membrane, whereas the kinase ...

In this paper, we propose a facilitator which finds capable and trustworthy partners on behalf of client users, which helps users form and maintain e-partnerships for electronic commerce and electronic collaboration. Unlike existing capability-based facilitators or matchmakers, the facilitator collects and maintains private “word-of-mouth” trust information as well as capabilities from each use...

This paper proposes a facilitator which finds capable and trustworthy partners on behalf of client users (agents), which helps agents form and maintain e-partnerships for electronic commerce. Unlike existing capability-based facilitators or matchmakers, the facilitator collects and maintains private “word-of-mouth” trust information as well as capabilities from each agent and uses the informati...

Individuals exposed to horrifying, life-threatening events are at heightened risk for posttraumatic stress disorder. Given the substantial personal and societal costs of chronic PTSD, mental health care professionals have developed early intervention methods designed to mitigate acute emotional distress and prevent the emergence of posttraumatic psychopathology. The method most widely used thro...
