The bias of cyclic periodogram with ssinc window is analyzed in both spectrum frequency direction and cycle frequency direction, and that the TA cyclic spectrum estimation is unbiased is analyzed. The average method of cyclic periodogram is also derived in terms of STFT.

The PZT plates were polarized in thickness direction. By using the deformation in the plane perpendicular to the direction of polarization, the rotation around Z axis was generated when the torsional vibration around Z axis mode was excited. And the rotation around X axis or Y axis was generated by combining the longitudinal vibration mode and the bending vibtration mode.

We also find that the metal-to-semiconductor transition can be driven by squashing the armchair nanotube along any direction. In case one starts with squashing the tube along a direction that preserves the mirror symmetry, all that needs to be done is to squash the tube to a larger extent, to a point where spontaneous symmetry breaking occurs.
