... negligibly small. The optical quality of the AlGaAs capping layer can be monitored by the PL intensity of the QW. In the sample capped at 450°C, the PL intensity is almost the same as that of the 580°C sample. ... 6:76 http://www.nanoscalereslett.com/content/6/1/76 Page 2 of 4 excess As atoms are difficult to remove even after post- growth annealing. Conclusion We...

... consistent with the hypothe- sis that the nonlinear structure of gait is dependent on the neural control of the forward progression of the center of mass during the stance phase of gait. As the mechanical actuator ... progression of the center of mass may also influence the nonlinear structure of human locomo- tion. In this investigation, we explored if th...
