The present study investigates how a conversational agent can facilitate explanation activity. An experiment was conducted where pairs of participants, who were enrolled in a psychology course, engaged in a task of explaining to their partners the meanings of concepts of technical terms taught in the course. During the task, they interacted with a(More)
Knowledge on domain swapping in vitro is increasing, but domain swapping may not occur regularly in vivo, and its information in cells is limited. Herein, we show that domain-swapped oligomers of a thermostable c-type cytochrome, Hydrogenobacter thermophilus cyt c552, are formed in E. coli which expresses cyt c552. The region containing the N-terminal(More)
The presented study is concerned with one aspect of the effect of a "whistleblower" or a person arousing or informing a different perspective on a collaborative problem-solving task. Its purpose is to find out, through an experiment, how a whistle-blower (which we called "Maverick") affects the facilitation of a breakthrough in a rule-discovery task. In the(More)
Since neural networks have superior information processing functions, many investigators attempt to model biological neurons and their networks. Furthermore, a number of studies of neural networks have recently been made with the purpose of applying engineering to the brain. In this study, we investigate the effect of STDP on the ability to extract phase(More)
Oxidized horse cytochrome c (cyt c) has been shown to oligomerize by domain swapping its C-terminal helix successively. We show that the structural and thermodynamic properties of dimeric Hydrogenobacter thermophilus (HT) cytochrome c(552) (cyt c(552)) and dimeric horse cyt c are different, although both proteins belong to the cyt c superfamily.

The study investigates learning activities of students making explanations about a key concept in an online system with a Pedagogical Conversational Agent providing (1) facilitation on learners' explanations from various views and (2)social facilitation prompts of other members in the classroom. A total of 314 learner's explanation activities were collected(More)
