Let γm,n denote the size of a minimum dominating set in the m× n grid graph. For the square grid graph, exact values for γn,n have earlier been published for n 6 19. By using a dynamic programming algorithm, the values of γm,n for m,n 6 29 are here obtained. Minimum dominating sets for square grid graphs up to size 29× 29 are depicted. ∗Supported by the Academy of Finland, Grant No. 132122 and ...

Looking across the board, we show t...

Thirty-six blast-exposed patients and twenty-nine non-blast-exposed control subjects were tested on a battery of behavioral and electrophysiological tests that have been shown to be sensitive to central auditory processing deficits. Abnormal performance among the blast-exposed patients was assessed with reference to normative values established as the mean performance on each test by the contro...

The purpose was to show that when a favor reduces a person's freedom, it arouses "psychological reactance," a motivational state aimed at restoration of this freedom. Ss, run individually, learned they were to make Ist-imprcssion ratings of another S (confederate) and then were given a soft drink by this S, prior to making the ratings. In a 2 X 2 design, the Ist-imprcssion ratings were given lo...
