In the ADC-MAC protocol [16], each node establishes a cooperation table, uses the shortest path algorithm to select the helper between itself and its recipient, and designates the helper in a request-to-send (RTS) packet.
Hence, work rate conflict is likely to be more acute between breeders and female helpers than between breeders and male helpers.
The chefs and their helpers nap between the lunch and dinner rushes by putting their heads on the table or lying across the restaurant chairs.
Forget the Tuna Bowls (Parcells versus Kraft, the Patriots' owner) and the Tuna Helper Bowls (between the Parcells disciples Belichick and Al Groh), these two teams have not played such an important game since the season finale in 1998, when both teams went to the playoffs.
In the present study, no difference in the apoptotic rate of T-helper lymphocytes between the two groups of patients was shown.
Chaotic, market-based arrangements with domestic helpers, the distrust between people in the Reform Era, and feelings about the precious only child all made Grace and John feel that they had no choice but to rely on the grandparents.
Another set of studies (Kuhlmeier et al. 2003; Hamlin et al. 2007) provide evidence that infants are not only sensitive to displays of agency, but also have a sense of (something like) cooperative behavior: they readily distinguish between helpers and hinderers.
Based on these findings, we tested the "concealed helper effects" hypothesis, which proposes that laying females reduce investment in eggs (with respect to their size, number, or quality) in a way that confounds helper effects and results in an absence of a relationship between helpers and breeding success.
There were significant positive relationships between the total number of helpers and reproductive success and between group size and reproductive success in both good and poor acorn years, but the effect sizes in poor years were much smaller than in good acorn years (Table 1).
In this way, a node gets information about the channel conditions between neighboring helpers and itself, as well as with potential destinations.
