Abstract: A method and an apparatus for acquiring channel information in a polarization division duplex system. An uplink signal transmitted from a terminal is received, the uplink signal indicating that a null subcarrier is disposed in a first subcarrier overlapped with a second subcarrier including a downlink pilot signal, and a self-interference channel is estimated by using a signal received from the null subcarrier. A signal corresponding to the null subcarrier from the uplink signal is removed, and channel information is acquired by estimating the uplink channel based on estimation results of the self-interference channel and a pilot signal included in the uplink signal from which the null subcarrier is removed.

Abstract: Disclosed herein is a microcolumn with a double aligner. The microcolumn is configured such that when an axis of an aperture of a limiting aperture is spaced apart from an original path of a particle beam, the path of the particle beam can be effectively compensated for in such a way that the path of the particle beam is aligned with the axis of the aperture of the limiting aperture by the double aligner. The microcolumn includes a source lens. The source lens includes at least two aligner layers which compensate for the path of the particle beam.

Abstract: Disclosed herein is a blade bucket structure for Savonius turbines. In the blade bucket structure, blade buckets on which resistance resulting from the flow of fluid occurs, are provided with a separated flow retardation means for reducing pressure drag force impeding rotation of a Savonius turbine. The separated flow retardation means can reduce resistance that acts in a direction opposite to the direction of rotation of the Savonius turbine because of variation in orientation of the blade buckets while rotating.
