Recurrent respiratory papillomatosis (RRP) is characterized by the recurrence of benign tumors (papillomata) in the aero digestive tract caused by Human Papilloma Virus.The burden for the patient and the society is non negligible, due to the high frequency of repetitive surgeries.The disease follows a bimodal age distribution.Usually the very first
MicroRNAs (miRNAs) are endogenously expressed noncoding RNA molecules that are believed to regulate multiple neurobiological processes.Expression studies have revealed distinct temporal expression patterns in the developing rodent and porcine brain, but comprehensive profiling in the developing human brain has not been previously reported.We perfor
The symmetrical bipolar configuration shows a great advantage in modular multilevel converter (MMC) based high-voltage dc-current (HVDC) transmission.In a bipolar MMC-HVDC system, station internal ac grounding faults foot pad right cause sub-module (SM) capacitors to discharge violently.These faults do great harm to MMCs and require special protect
The curvature of the NURBS curve varies along its trajectory, therefore, the commonly used feedrate-planning method, which based Stationery on the acceleration/deceleration (Acc/Dec) model, is difficult to be directly applied in CNC machining of a NURBS curve.To address this problem, a feedrate-planning method based on the critical constraint curve
