Clear as black and white: the effects of ambiguous rhetoric depend on candidate race [PDF]

, 2018
Campaign advisors and political scientists have long acknowledged the benefits of ambiguous position taking. We argue, however, that these benefits do not extend to black candidates facing nonblack voters.

In-cylinder flow field characteristics and evolution mechanism of unthrottled gasoline engine with Early Intake Valve Closure (EIVC) under different operating conditions

Case Studies in Thermal Engineering
The efficiency improvement of traditional gasoline engines is hindered by a limited compression ratio due to knock and severe pumping losses caused by fixed valve lift. Unthrottled technology has emerged as a solution relying on variable valve mechanisms.
