Effect of titin phosphorylation on degradation of titin from skeletal muscles by Ying Wang, Xin Li, Dequan Zhang, Zheng Li, Baocai Xu, Jie Zhu

“…There were 20, 16 and 12 phosphorylated sites identified by iTRAQ in the PKA, control and AP group, respectively. 3D structure of dephosphorylated titin fragment was simulated and its molecular dynamics trajectory analysis was performed using Discovery StudioTM. The dihedral angle in AP group was less and the dephosphorylated fragment had a higher kinetic energy and total energy. …”

Suspended Load Path Tracking Control Strategy Using a Tilt-Rotor UAV by M. A. Santos, B. S. Rego, G. V. Raffo, A. Ferramosca

“…Furthermore, a model predictive control (MPC) strategy is proposed for path tracking of the suspended load with stabilization of the tilt-rotor UAV when parametric uncertainties and external disturbances affect the load, the rope’s length and total system mass vary during taking-off and landing, and the desired yaw angle changes throughout the trajectory. Finally, numerical experiments are presented to corroborate the good performance of the proposed strategy.…”

High Accuracy 2D-DOA Estimation for Conformal Array Using PARAFAC by Liangtian Wan, Weijian Si, Lutao Liu, Zuoxi Tian, Naixing Feng

“…The paramount difficulty for DOA estimation is the coupling between the angle information and polarization parameter. Based on the characteristic of the cylindrical conformal array, the decoupling between the polarization parameter and DOA can be realized with a specially designed array structure. 2D-DOA estimation of the cylindrical conformal array is accomplished via parallel factor analysis (PARAFAC) theory. …”
