A complete algebraic characterization of the first integrals Higgins–Selkov, Selkov and Brusellator oscillators is given here. The existence symmetries sometimes forces such integrals. nonexistence centers for also proved. In order to determine Puiseux integrability systems, multiple solutions are studied.

Higgins et al. (2006) report several statistically significant partial correlates with U.S. per capita income growth. However, Levine and Renelt (1992) demonstrate that such correlations are hardly ever robust to changing the combination of conditioning variables included. We ask whether the same is true for the variables identified as important by Higgins et al. Using the extreme bounds analys...

Psychological research suggests that trying to avoid a negative outcome and trying to attain a positive outcome have different effects on performance (Higgins, 1997). We explored this prospect by examining free throw performance among NBA basketball players at the ends of games when the player’s team was ahead or behind in a clutch situation. Players tended to shoot worse than their career aver...

It is shown that the molecular symmetry groups can be obtained as the automorphism groups of edge-weighted Euclidean graphs. Graph theory provides an elegant and natural representation of molecular symmetry. The resulting group expressed in terms of permutations is isomorphic to the permutation-inversion group of Longuet-Higgins or the permutational subgroup in case inversion operations do not ...
