Abstract: The video data output from the dot-inversion driver is re-arranged in the present invention. According this re-arranged method, the video data output from the even data lines or odd data lines is delayed for one scan line scan time. Then, the re-arranged video data are applied to the liquid crystal display structure whose thin film transistors connected with the same scan line are arranged in alternatingly up-down form to store row-inversion driving data in the pixel region.

Abstract: The present invention relates to a method of controlling the characteristics of a double relaxation oscillation SQUID having a reference junction. In the method of controlling characteristics of a reference junction-type double relaxation oscillation SQUID (RJ-DROS) having a signal SQUID and a reference junction, a reference DC current flows through the reference junction in order to control the characteristics of the DROS. A modulation width of an averaged relaxation voltage, which reacts to a magnetic flux, may be controlled at the reference junction. An amount (modulation depth) of an averaged relaxation voltage, which reacts to a magnetic flux, may be controlled at the reference junction. An amount of an operation application current may be controlled at the reference junction. Accordingly, the reference current of the reference junction can be changed by causing the current to flow through the reference junction.

Abstract: Provided is a layout method for protein-protein interaction networks based on a seed protein, which is for performing multiple stages of nesting centered on a node having a high degree of physical relationship, and performing multiple stages of extension and force directed placement (FDP) with respect to a final nest graph. The layout method includes the steps of: a) extracting a node list of each sub-graph constituting a protein-protein interaction network, and aligning the node list according to adjacency of nodes; b) selecting a seed protein from the aligned node list according to node priority and nest relationship with another node; c) nesting adjacent nodes centered on the selected seed protein to generate a nested node; and d) selecting an initial position of the generated nested node, placing the nodes of the nested nodes on respective division points, centered on the seed protein, and then performing layout.

The turbofan includes a rotating plate rotated by a driving motor, a plurality of blades having first ends connected to an outer peripheral portion of a front surface of the rotating plate while being arranged in a radial pattern, a shroud having an annular shape and being integrally formed with second ends of the blades, in which the shroud has an inner diameter equal to or larger than a diameter of the rotating plate, and an auxiliary rotating plate having a diameter larger than the diameter of the rotating plate and being fixed to the rotating plate. Since the inner diameter of the shroud is equal to or larger than the rotating plate, the turbofan is integrally formed with the shroud by a mold.

Abstract: Disclosed is a Bluetooth® moving picture stream transmission terminal for moving picture data stream transmission through Bluetooth® to a moving picture output device. The Bluetooth® terminal provides the moving picture output device with the optimized streaming service by either acquiring the transcoding reference variable according to decoding function included in the moving picture output device when the Audio Video Distribution Transport Protocol (AVDTP) channel of the moving picture output device is opened, or acquiring the transcoding reference variable by using the newly defined transcoding reference variable request/response message after opening the AVDTP channel, and by setting an encoding environment with reference to the acquired transcoding reference variable, and encoding the corresponding moving picture and transmitting stream of the encoded moving picture through Bluetooth®.
