Spindle microtubules capture and segregate chromosomes and, therefore, their assembly is an essential event in mitosis.To carry out their mission, many key players for microtubule formation need to be strictly orchestrated.Particularly, proteins that assemble the spindle need to be translocated at appropriate sites during mitosis.A small GTPase (hy
In order to accurately calculate the sofia barclay sexy 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 s
In this paper, a mask region-based convolutional neural network (Mask R-CNN) is used to improve the performance of machine vision in the challenging task of detecting peduncles and fruits of green sweet peppers (Capsicum annuum L.) in greenhouses.One of the most complicated stages of the sweet pepper harvesting process is to achieve a fr9967 precis
This paper considers the problem of estimating the motion parameters of a low-observable high-speed maneuvering target with high-order motions, where the target’s complex motions will result in the range migration (RM) and Doppler frequency migration (DFM) effects within the observation time interval, which will significantly affect the rada
