Termite queens close the sperm gates of eggs to switch from sexual to asexual reproduction.
Males and females are in conflict over genetic transmission in the evolution of parthenogenesis, because it enhances female reproductive output but deprives the males' genetic contribution. For males, any trait that coerces females into sexual reproduction should increase their fitness. However, in the termite Reticulitermes speratus, queens produce their replacements (neotenic queens) partheno...

We suggest a model that incorporates "bargaining ability" as another source for heterogeneity across players. This bargaining ability for the buyer determines how many o¤ers he will be able to turn down before he walks away. For the seller this ability determine...
متن کاملGates
Gates are a new notation for representing mixture models and context-sensitive independence in factor graphs. Factor graphs provide a natural representation for message-passing algorithms, such as expectation propagation. However, message passing in mixture models is not well captured by factor graphs unless the entire mixture is represented by one factor, because the message equations have a c...
