N-Aryl-S,S-dimethylsulfimides 3 (Ar = 4-NO2C6H4), 4 (Ar = Ph) and 5 (Ar = 4- Tol) react with Appel salt 1 to give the corresponding N-aryl-(4-chloro-5H-1, 2,3- dithiazolylidene)benzenamines 8 (Ar = 4-NO2C6H4), 9 (Ar = Ph) and 10 (Ar = 4-Tol) in 84, 94 and 87% yields, respectively. The reaction proceeds in the absence of base and a proposed reaction mechanism is given. © 2009 by the authorslicensee Molecular Diversity Preservation International, Basel, Switzerland.

ABA: Argumentation based agents Kakas, Antonis C.; Amgoud, L.; Kern-Isberner, G.; Maudet, N.; Moraïtis, Pavlos (2012)Many works have identified the potential benefits of using argumentation in multiagent settings, as a way to implement the capabilities of agents (eg. decision making, communication, negotiation) when confronted with ...
Immunomodulatory therapy for sepsis: An update Christaki, Eirini; Anyfanti, Panagiota; Opal, Steven M. (2011)Currently the treatment mainstay of sepsis is early and appropriate antibiotic therapy, accompanied by aggressive fluid administration, the use of vasopressors when needed and the prompt initiation of measures to support ...
Argumentation Based Decision Making for Autonomous Agents Kakas, Antonis C.; Moraïtis, Pavlos (2003)This paper presents an argumentation based framework to support the decision making of an agent within a modular architecture for agents. The proposed argumentation framework is dynamic, with arguments and their strength ...
