Abstract: It is well known that relay-based DF cooperative wireless networks outperform AF cooperative networks. However, this performance enhancement is achievable through considerable signal processing (precoding/decoding) at relay nodes. To reduce the precoding/decoding complexity, a method for precoding and decoding a distributive MIMO channel in the relay-based DF cooperative wireless network using EVD based on properties of Jacket transformations is provided.

Abstract: A liquid crystal display device includes a first substrate having a gate line and two data lines crossing with the gate line to define a pixel, a first pixel electrode connected to the gate line and the first data line, and a second pixel electrode connected to the gate line and the second data line. A second substrate opposes the first substrate and includes a common electrode having a common electrode cutting pattern. The pixel electrode includes a pixel electrode cutting pattern to form domains and sub domains in the pixel with the common electrode cutting pattern. A liquid crystal layer is arranged between the first and second substrates. The pixel electrodes include bent portions. The pixel electrode and the common electrode include sub cutting patterns extending towards the sub domains at the bent portions.

Abstract: The present invention relates to a lyotropic chromonic liquid crystal composition, a method for manufacturing a lyotropic chromonic liquid crystal coating film and a lyotropic chromonic liquid crystal coating film manufactured thereby. The lyotropic chromonic liquid crystal composition of the present invention includes chromonic liquid crystal compounds and monomers each having opposing acid-base properties. Use of the lyotropic chromonic liquid crystal composition in the formation of optical films leads to improvements in electrical and optical properties such as mechanical strength, an insulating characteristic and a refractive index.

Abstract: Disclosed is a nozzle block for electrospinning which is able to simultaneously electrically spin two or more different types of polymer spinning dopes, wherein a single-layer distribution plate for dividing a planar space within the nozzle block into two or more segments is installed within the nozzle block. The apparatus is simple because a single-layer distribution plate is installed instead of a conventional multi layer distribution plate. A hybrid nano fiber laminate can be prepared without any additional laminating procedure because two or more different polymer spinning dopes can be simultaneously electrically spun through different nozzles arranged within the same nozzle block. It is possible to prepare a hybrid nano fiber nonwoven fabric or filaments or the like composed of two or more types of nano fibers different in thermal properties or physical properties because their fiber diameter or polymer type are different from each other.

The marker for liver cancer diagnosis comprises at least one polynucleotide selected from a group consisting of the following polynucleotides (a) to (d):(a) polynucleotide having a base sequence defined by Seq. No. 1 or substantially similar sequence to Seq. No. 1; (b) polynucleotide encoding specific protein composed of an amino acid sequence defined by Seq. No. 2; (c) polynucleotide that comprises Seq. No. 2, in which at least one amino acid is substituted, deleted, inserted and/or added, and that encodes protein functionally equivalent to specific protein composed of Seq. No. 2; and (d) polynucleotide that is encoded by another polynucleotide hybridized with polynucleotide having Seq. No. 1 under stringent conditions, and that encodes protein functionally equivalent to specific protein composed of Seq. No. 2.

Abstract: Disclosed are a nano fiber reinforced composite and a method of manufacturing the same. A spinning dope (nano fiber forming spinning dope) having a viscosity capable of fiber formation upon electrospinning and a spinning dope (spinning dope for matrix) having a viscosity incapable of fiber formation upon electrospinning are electrically spun onto the same collector with a high voltage applied thereto through different nozzles of the same nozzle block with a high voltage applied thereto. In the nano fiber reinforced composite, nano fibers are uniformly arranged between matrix components with no fibers formed therein, the nano fibers being arranged at an orientation angle of 90° or less relative to the longitudinal axis of the composite material.
