The multi low speed,high-loaded bearing installed on same axis,different locations of the bearing fault pulse will appear aliasing coupling phenomenon,resulting in fault signal identification difficult.In this regard,based on the characteristic of corner-domain and full vector empirical mode decomposition to identify and diagnose the vibration sour
Abstract Increased atmospheric CO2 is driving ocean acidification (OA), and potential changes in marine ecosystems.Research shows that both planktonic and benthic communities are affected, but how these changes flower pot are linked remains unresolved.Here we show experimentally that decreasing seawater pH (from pH 8.1 to 7.8 and 7.4) leads to redu
The endeavour to control increasingly larger systems of particles at the quantum level is a natural goal, and will be a driving force for the physical Bateries sciences in the coming decades.The control of a many-body system at the highest level possible can indeed be regarded as the ultimate form of engineering.Within this general research avenue,
