متن کاملCosmological evolution with brane-bulk energy exchange
The consequences for the brane cosmological evolution of energy exchange between the brane and the bulk are analysed in detail, in the context of a non-factorizable background geometry with vanishing effective cosmological constant on the brane. A rich variety of brane cosmologies is obtained, depending on the precise mechanism of energy transfer, the equation of state of brane-matter and the s...

15 صفحه اولAdaptive specializations, social exchange, and the evolution of human intelligence
Blank-slate theories of human intelligence propose that reasoning is carried out by general-purpose operations applied uniformly across contents. An evolutionary approach implies a radically different model ofhuman intelligence. The task demandsofdifferent adaptive problems select for functionally specialized problem-solving strategies, unleashing massive increases in problem-solving power for ...
