In order to accurately calculate Carafes the meshing efficiency of the new internal S-gears, a time-varying friction model of the elastohydrodynamic lubrication is established considering the surface sliding of the gear tooth, lubricating oil condition and load.The lubrication mechanism of the meshing tooth surface is analyzed, and the sliding fric

Background Aurora kinases play an essential role in the orchestration of chromosome separation and cytokinesis during mitosis.Small-molecule inhibition of the aurora kinases has been shown to result in inhibition of cell division, phosphorylation of histone H3 and the induction of apoptosis in a number of cell systems.These characteristics have led

Abstract Ferroelectricity in crystalline hafnium oxide has attracted considerable attention because of its potential application for memory devices.A recent breakthrough involves electric-field-induced crystallization, allowing HfO2-based materials to avoid high-temperature crystallization, which is unexpected in the back-end-of-line process.Howeve

The temporal change of an Adelie penguin population Pickles was observed in the B4 colony, Northern Rookery, Cape Bird, Ross Island in the 1978-79 summer season.Between January 1 and 24,1979,after the preparatory observation in late December, the number and position of occupied nests, occupying birds, re-occupying nonbreeders and chicks were observ
