The four types of opposites are the best represented.
Sometimes one protein simultaneously transports two types of molecules in opposite directions.
We separated hub regions into provincial and connector classes, and showed that lesions of the two types of hubs had opposite effects on the small-world organization of the remaining network.
Bonding patterns similar to those observed in the present work might in fact form also with colloids carrying two types of patches, two opposite polar patches of type A and one equatorial patch of type B, such that only AB bonds are possible.
We tested the significance of the difference between population trend estimates from the carcass suvey and road transects by using as the P value the proportion of bootstrap/Monte Carlo replicates in which the difference between the two types of estimate was of opposite sign to that from the point estimates.
The two types of games have exactly opposite characteristics and players' behavior.
The fact that no competition concept falls with the range 0<γ<1 and, as argued elsewhere [60], γ = 1 is itself problematic strongly suggests that these two types of competition are not opposite ends of the same spectrum, but are fundamentally different types of competition processes that can both operate concurrently, though on different time scales.
Life history theory has shown that these two types of fishery act in opposite directions on age at maturation (Law and Grey 1989): while the feeder fishery favors early-maturing fish that manage to reproduce while still alive, a high mortality on the spawning grounds favor fish that are large when they risk that mortality to reproduce and therefore selects for late maturation.
The two types of analyses are distinguished by opposite limiting signs, providing reliable, simplified statistical results.
The first mode of response is explicitly represented by the terms with the factors Ψ and Ψ 2. Note here that both brackets in Eq. (1) include two types of terms that correspond to opposite symmetry properties with respect to z and Ψ.
So the two types of signal pathway display an opposite effect and sustain the regulation of DCs differentiation by crosstalking to each other.
