Corrugator supercilii muscle activity is considered an objective measure of valence because it increases in response to negatively valenced facial expressions (angry) and decreases to positive expressions (happy). The authors sought to determine if corrugator activity could be used as an objective measure of positivity-negativity bias. The authors recorded corrugator responses as participants r...

On the biotransformation of phenol and monofluorophenols by the cultured cells of Eucalyptus perriniana, phenyl and fluorophenyl b-D-glucosides were isolated after a 1-h incubation. Especially, the yield of 2-fluorophenol is higher than those of the other substrates, i.e., phenol, 3and 4-fluorophenols. These results indicated that E. perriniana cells selectively glycosylate the hydroxyl group o...

for square-free integers m, and we have obtained that the special value L(Em, 1) of L-function for Em is described in terms of positive definite ternary quadratic forms. It is an analogue result of Tunnell’s [Tun] for the classical congruent number problem. In this paper, we use a result of Gauss on ternary quadratic forms to give more useful criterion for non-2π/3and non-2π/3-congruentness. So...

A procedure for chromatographic separation of 3and 4-substituted anilines on thin layers of silica gel in various systems has been developed with purpose of their identification and control of their purity. The chro­ matographic values Ям both from adsorption and partition chromatogra­ phies were correlated with physicochemical parameters pÄľa, er, and к. The relationship between RM from partit...

Based on the predictions of a computational model, we test preschoolers’ ability to reason about stream location effects: reasoning that interventions that occur on a common part of a causal process should be more likely to affect multiple relations, than interventions which occur on independent parts of a causal process. In two experiments, we show that 3and 4year-olds both show a stream locat...

In this paper, Multi-Layer Perceptron and RadialBasis Function Neural Networks, along with the Nearest Neighbour approach and linear regression are utilized for flash-flood forecasting in the mountainous Nysa Klodzka river catchment. It turned out that the Radial-Basis Function Neural Network is the best model for 3and 6-h lead time prediction and the only reliable one for 9-h lead time forecas...

We suggest a new mechanism for interarea electric power system oscillations in which two oscillatory modes interact near a strong resonance to cause one of the modes to subsequently become unstable. The possibility of this mechanism for oscillations is shown by theory and computational examples. Theory suggests that passing near strong resonance can be expected in general power system models. T...

A graph is semi-symmetric if it is regular and edge transitive but not vertex transitive. The 3and 4-valent semi-symmetric graphs are wellstudied. Several papers describe infinite families of such graphs and their properties. 3-valent semi-symmetric graphs have been completely classified up to 768 vertices. The goal of this project is to extend this work to 5-valent semi-symmetric graphs. In th...

Generation of 3and 4-dimensional graphics is discussed in the context of stellarator ballooning mode theory and the nonlinear dynamics of a 4-dimensional symplectic map (two coupled area-preserving maps). These provide case studies for informally reviewing the history of some commercially available visualization software for personal computers (Macintosh and Windows) developed by US small-to-me...
