Laser Cooling of 85Rb Atoms to the Recoil Temperature Limit
, 2018 We demonstrate the laser cooling of 85Rb atoms in a two-dimensional optical lattice. We follow the two-step degenerate Raman sideband cooling scheme [Kerman et al., Phys. Rev. Lett.

Cooling Rates in Hot-Poured Bituminous Sealants
Transportation Research Record: Journal of the Transportation Research Board, 2006 The performance of bituminous sealants applied to cracks and joints is partly governed by installation. An important installation parameter yet to be investigated is the sealant rate of cooling after it is poured hot. Cooling rates affect sealant microstructure and rheology, adhesion at the sealant–hot-mix asphalt interface, and the time during which ...

Monitoring body temperature during moderate intensity exercise and inactive recovery in the cold
Current Issues in Sport Science, 2019 Exposure to cold ambient conditions during outdoor recreation can lead to significant heat loss. It is unknown how fast body temperature decreases or how fast a person could become hypothermic in cold temperatures.
