On the theoretical origin and applicability of the potential theory approach to predict mixed-gas adsorption on solid surfaces from single-gas adsorption isotherms
Chemical Engineering Science, 1995Co-Authors: Władysław Rudziński, Krzysztof Nieszporek, Hee Moon, Hyun-ku RheeAbstract:Abstract A rigorous theoretical development of the Potential Theory Approach for predicting mixed-gas adsorption on solids from single-gas adsorption isotherms is given. That approach requires very simple computer calculations making it very attractive for process design and control in industrial applications of mixed-gas adsorption on solids. It is shown that the “coalescence” Operation can be treated as a purely Numerical Operation not involving the knowledge or assumptions about some physical quantities the meaning of which is not clear. However, it is also shown that the traditional coalescence Operation is not the best way to elucidate the values of the parameters which are necessary to predict mixed-gas adsorption equilibria. A more effective way to determine the values of these parameters better, based on a theoretical analysis of single-gas adsorption isotherms, is proposed.

Goal-oriented, flexible use of Numerical Operations by monkeys.
Animal cognition, 2013Co-Authors: Sumito Okuyama, Jun-ichi Iwata, Jun Tanji, Hajime MushiakeAbstract:Previous studies have shown that elementary aspects of Numerical abilities have developed in non-human primates. In the present study, we explored the potential for the development of a novel ability in the use of Numerical Operations by macaque monkeys (Macaca fuscata): adequate selection of a series of Numerical actions toward achieving a behavioral goal. We trained monkeys to use a pair of devices to selectively add or subtract items to/from a digital array in order to match a previously viewed sample array. The monkeys determined whether to add or subtract on the basis of the feedback about numerosity given to the monkeys, which was displayed as an outcome of each step of the Numerical Operation. We also found that monkeys adapted flexibly to changes in the Numerical rule that determined the relationship between device use and Numerical Operation. Our model analysis found that the numerosity-based model was a better fit for the monkeys' performance than was the reward-expectation-based model. Such a capacity for goal-oriented selection of Numerical Operations suggests a mechanism by which monkeys use Numerical representations for purposeful behaviors.
