Function symmetries and decoded-PLA realization

Decoded PLA (programmable logic array) has a distinct advantage over ordinary PLA, in that it can realize complex functions with smaller chip area. This paper shows that decoded PLA is particularly suitable if the function to be realized has some form of symmetry. The paper describes a new approach for d-PLA realizations using symmetries. It also describes the computer simulation which helps in the detection and use of such symmetries. Two such realizations are also described.     

The accuracy of social value prediction: Actor and observer influences.

Research was conducted with 240 undergraduates to determine the relationship between an observer's own value orientation and his/her ability to detect the value orientations of others. Choices in a series of 3-choice decomposed games were used to classify Ss as altruistic, cooperative, individualistic, or competitive in orientation. Subsequently, Ss observed a hypothetical person (the "chooser") select between self- and other-outcome alternatives in a series of 4-choice decomposed games. The chooser's behavior was preprogrammed in accordance with an altruistic, cooperative, individualistic, or competitive orientation. Results confirm that Ss' own values affected their relative abilities to predict the different choosers' behaviors. Cooperative and individualistic Ss demonstrated comparatively high levels of predictive accuracy regardless of the chooser's social value orientation, whereas altruistic and competitive Ss' predictive accuracy varied as a function of the chooser's orientation. Results for cooperative and competitive Ss resembled the "triangle" effect first observed by H. H. Kelley and A. J. Stahelski (1970).

Syntheses and properties of surfactants containing organometals: IV. Organo silicone

The authors synthesized nonionic surfactants containing dimethylpolysilane, dimethylpolysilmethylene and dimethylopolysiloxane as the hydrophobic groups, and investigated their surface activities. In their ability to lower the aqueous surface tension, the polysiloxane surfactants were the most active, and there is little reason to choose between the other two kinds of surfactants. With regard to the ability of lowering the interfacial tension between water and silicone oil, the polysilmethylene surfactants were most effective when the concentration of aqueous solution was below 0.5 wt %. Above this concentration, however, the polysiloxane surfactants were superior. Also investigated was the lowering of surface tension of nonaqueous polyols and their ability to wet low energy hydrophobic surfaces such as polyethylene.     

Fluctuation phenomena below the superconducting transition

The fluctuation propagator for the superconducting order parameter belowT _c is derived for a gapless superconductor. The fluctuation of the order parameter consists of two distinct modes: the fluctuations of the phase and the modulus of the order parameter. The former fluctuation obeys a phononlike dispersion, while the latter fluctuation is described by a damping diffusion type equation. The present theory gives an account of the fluctuation-induced Josephson effect belowT _c observed recently by Carlson and Goldman.
