The influence of optical molasses in loading a shallow optical trap [PDF]

open access: yes, 2008
We have examined loading of 85Rb atoms into a shallow Far-Off-Resonance Trap (FORT) from an optical molasses and compared it to loading from a Magneto-Optical Trap (MOT). We found that substantially more atoms could be loaded into the FORT via an optical molasses as compared to loading from the MOT alone. To determine why this was the case, we measured

Contact Load and Elastohydrodynamic Lubrication Analysis of Eccentric Bearings in RV Reducer Considering the Effects of Roller Profile Modification

open access: yesLubricants
The mechanical and tribological behavior of eccentric bearings is crucial for the performance of a RV reducer. By combining the finite element model (FEM) and the elastohydrodynamic lubrication (EHL) method, a comprehensive model for the cylindrical ...

Body size evolution as a catalyst for diversification of copulation strategies and its spillover effects on genital evolution and phylogenetic divergence in terrestrial arthropods

open access: yesPopulation Ecology, EarlyView.
A scenario in which divergent selection derived from ecological environments leads to genital divergence through body size evolution. Abstract To explore how ecological diversity contributes to the establishment of ecologically similar species with sexual divergence, this review focuses on body size—an environmentally influenced trait that determines ...
