Collapse of desert bird populations likely due to heat stress from climate change（图）
Collapse bird populations due heat stress climate change
2019/10/17
As temperatures rise, desert birds need more water to cool off. At the same time, deserts are becoming drier, setting some species up for a severe crash, if not extinction, according to a new study pu...
A Round-Collapse Theorem for Computationally-Sound Protocols; or, TFNP is Hard (on Average) in Pessiland
TFNP round-collapse average-case hardness
2019/6/26
This result follows from a more general theory of interactive average-case complexity, and in particular, a novel round-collapse theorem for computationally-sound protocols, analogous to Babai-Moran's...
