Cilia identifiable by light microscopy occur extremely rarely in malignant tumor cells. This report documents the presence of cilia on exfoliated malignant tumor cells shed from an ovarian adenocarcinoma. Cilia-bearing tumor cells were observed in abdominal and pleural fluids. These cilia occurred at atypical locations. They were observed as unipolar,(More)
A nonlinear control scheme for active magnetic bearings is presented in this work. Magnet winding currents are chosen as control inputs for the electromechanical dynamics, which are linearized using feedback linearization. Then, the desired magnet currents are enforced by sliding mode control design of the electromagnetic dynamics. The overall control(More)
