Abstract A 7 amino acid deletion in Gag p6 (P6delta7) emerged in Chinese prevalent HIV-1 strain CRF07_BC from different epidemic regions.It is important to determine whether this mutation could be transmitted and spread.In this study, HIV-1 Gag sequences from 5 different epidemic regions in China were collected to trace the transmission linkage and
In the field of heavy-duty transportation of electric locomotives, the power of traction converters can reach MW, but the switching frequency needs to be kept at several hundred Hz.In addition, the converter needs to maintain a high transient response to load changes and keep grid-side harmonics at a low level, which is difficult to Out Of Balance
This paper proposes a modified swing control for a nonlinear inverted pendulum system by PINK HIMALAYAN SALT TOOTHPASTE utilizing the sliding mode controller based on the on-line tuningBeesalgorithm as speed of optimization and accuracy of results.The goal of the proposed nonlinear controller is to obtainthe optimal force control action for the pen
