Adaptive Sliding Mode Control of a 6-DOF RLED Robot Manipulator with Uncertain Parameters and External Disturbances

This paper addresses the end-effector position and orientation tracking problem of a 6-degrees of freedom (DOF) rigid link electrically driven (RLED) revolute joint serial robot manipulator with uncertain parameters and external disturbances.System uncertainties and external disturbances are bounded but their upper limits are unknown.The input matr

Genome-wide analysis of the rice PPR gene family and their expression profiles under different stress treatments

Abstract Background Pentatricopeptide-repeat proteins (PPRs) are characterized by tandem arrays of a degenerate 35-amino-acid (PPR motifs), which can bind RNA strands and participate in post-transcription.PPR proteins family is one of the largest families in land plants and play important roles in organelle RNA metabolism and plant development.Howe
