Words that are read aloud are more memorable than words that are read silently. The boundaries of this production effect (MacLeod, Gopie, Hourihan, Neary, & Ozubko, Journal of experimental psychology: learning, memory, and cognition, 36, 671-685, 2010) have been found to extend beyond speech. MacLeod and colleagues demonstrated that mouthing also facilitates memory, leading them to speculate th...

We present a detailed study of ant-dipping among the wild chimpanzees (Pan troglodytes verus) of Bossou, in southeastern Guinea, West Africa. Observations suggest a strong influence of prey (Dorylusspp.) characteristics, including aggressiveness and/or gregariousness, on tool length and technique employed by the chimpanzees. Bossou chimpanzees exhibit two ant-dipping techniques: 1) direct mouth...

The electric power system is one of the largest, most complicated, and most important cyber-physical systems in the world. The link between the cyber and physical level is the Supervisory Control and Data Acquisition (SCADA) systems and Energy Management Systems (EMS). Their functions include monitoring the real-time system operation through state estimation (SE), controlling the system to oper...

An eye-tracking experiment investigated where deaf native signers (N = 9) and hearing beginning signers (N = 10) look while comprehending a short narrative and a spatial description in American Sign Language produced live by a fluent signer. Both groups fixated primarily on the signer's face (more than 80% of the time) but differed with respect to fixation location. Beginning signers fixated on...

This paper proposes a blockchain based trust management method for agents in multi-agent system (MAS). In this work, three objectives are achieved: trust, cooperation and privacy. The of depends on the credibility evaluators, which is verified using proposed methods distortion, consistency reliability. To enhance between agents, tit-3-for-tat (T3FT) repeated game strategy developed. more forgiv...

The effect of odor on cognitive and emotional processes has been studied in adults and children, but less so in infants. In this study twenty-seven six-month-olds were presented with a video while in either an odor (pine or baby-powder) or a no odor control condition. The video was a 92-s audiovisual presentation of a woman expressing happiness and sadness, with the order of emotion counterbala...

Reputation systems aggregate mutual feedback of interacting peers into a “reputation” metric for each participant. This is then available to prospective service “requesters” (clients) for the purpose of evaluation and subsequent selection of potential service “providers” (servers). For a reputation framework to be effective, it is paramount for both the individual feedback and the reputation st...

Mobile cloud computing (MCC) is an emerging technology that has gained ever-increasing popularity, which makes the generation and large-scale collection of private personal data possible. However, new security issues arise when MCC offers big data analytics and management services. In particular, there is an absence of fine-grained secure access control model to protect privacy information from...
