A simulation technique is described for quantifying the contribution of three-body interactions to the thermodynamical properties of coarse-grained representations of complex fluids. The method is based on a new approach for determining virial coefficients from the measured volume-dependent asymptote of a certain structural function. By comparing the third virial coefficient B3 for a complex fl...

The postoperative retention and reversal of go, no-go avoidance reflex differentiation with symmetrical and asymmetrical reinforcement were studied in dogs with prefrontal lesions and unoperated controls. The general pattern of the influence of such experimental variables as type of differentiation task an,d quality and arrangement of conditioned stimuli' was similar to that oberved preoperativ...

The present review summarized the factors or determinants that may explain parasite diversity among host species and the consequences of this parasite diversity on the evolution of host-life history traits. As host-parasite interactions are asymmetrical exploited-exploiter relationships, ecological and epidemiological theories produce hypotheses to find the potential determinants of parasite sp...

The synthesis of keto-heptamethine derivatives has been expanded to various new symmetrical and asymmetrical structures, including an unprecedented di-anionic keto-polymethine. The spectroscopic behavior of these new dyes has been systematically and thoroughly investigated, revealing that the formation of hydrogen bond interactions with protic solvents is responsible for a dramatic enhancement ...

Symmetry breaking of the excited state of a linear quadrupolar acceptor-donor-acceptor molecule was investigated using time-resolved infrared spectroscopy in 55 solvents allowing the influence of several solute-solvent interactions to be examined separately. No symmetry breaking was found in nonpolar solvents irrespective of their refractive index, indicating that differences in dispersion inte...
