Is it possible to design affective artificial agents and if so, why should we care? This paper addresses both questions by laying out a program for systematically defining and evaluating possible functional roles of affective states in architectures for virtual and robotic artificial agents. It provides functional and architectural characterizations for simple and complex affective states, disc...

Cis-spliced acceptors can be converted to trans-splicing acceptors if the donor site upstream is mutated, and similarly an SL addition site will be cis-spliced if a donor site is inserted upstream. What is the function of SL trans-splicing? SL addition provides the cell with an alternative way of capping mRNAs, a modification required for mRNA stability, transport and translation. The standard ...
