Provided are an antibody for sexing sperms and use thereof, and more particularly, a composition for and a method of sexing sperms by using the antibody, and a method of producing an animal of a particular sex. In the present disclosure, it was confirmed that agglutination of Y chromosome sperms may be induced by treatment of the antibody, thereby easily sorting X chromosome sperms and Y chromosome sperms. Therefore, it is possible to produce a large number of customized animals of a particular sex and to selectively produce livestock of a desired sex, and therefore, it is expected to contribute to planed breeding, breeding improvement, and efficient management.

Provided is a method and a device for precoding in a wireless communication system. The method for precoding comprises the following steps: generating a first precoding matrix, W1, for deciding the transmission power of one transmission antenna from a plurality of transmission antennas as the maximum power per antenna; generating a zero forcing (ZF) precoding matrix, Ti, which does not influence the transmission antenna having the power which is decided as the maximum power per antenna, based on the (i−1)th precoding matrix Wi−1 (i=2, 3, . . . ); determining αi, a constant which has the transmission power of one transmission antenna from the rest of the transmission antennas, which do not have the transmission power as the maximum power per antenna, based on the Ti; and generating the ith precoding matrix Wi based on the Ti and the αi.

A method and apparatus of configuring a multi-cell precoding matrix for a multiple input multiple output (MIMO) operation in a wireless communication system in which a plurality of base stations participate in cooperative communication is provided. A multi-cell precoding matrix is configured using one or more single-cell precoding matrices, and wherein coefficients to be multiplied by the single-cell precoding matrices satisfy a condition in which the product between the multi-cell precoding matrix and a Hermitian matrix of the multi-cell precoding matrix is a unitary matrix. According to the embodiment of the present invention, it is not necessary for all base stations to perfectly know channel information. In addition, a feedback overhead is not high, and complexity is low.

A feedback method for interference alignment in wireless network having K transmitters and K receivers is provides. The method comprising: transmitting, performed by transmitter n−1, a precoding vector of transmitter n−1 (n is a integer between 2 and K−1) to receiver n+1; calculating, performed by the receiver n+1, a precoding vector of transmitter n using the precoding vector of transmitter n−1; and transmitting, performed by the receiver n+1, the precoding vector of transmitter n to transmitter n.
摘要:
A method for transmitting channel information in a multi-antenna system, the method includes calculating channel quality information (CQI) with respect to each mode, comparing the CQI with respect to each mode to a threshold value with respect to each mode, and transmitting CQI with respect to a mode having higher CQI than the threshold value as channel information. Good performance can be achieved regardless of the number of users or an SNR of users.
摘要:
The present invention relates, in general, to air cleaning apparatuses and, more particularly, to a ceiling-mounted air cleaning apparatus which can be conveniently installed and used as room ventilation equipment, which discharges contaminated indoor air to the outside a room and supplies fresh outdoor air to the interior of a room so as to maintain clean air in the interior of the room. The ceiling-mounted air cleaning apparatus of the present invention includes an upper casing (10), which is removably mounted to a ceiling, a lower casing (20), which is separably coupled to the upper casing, a filter unit (30), which is provided between the upper and lower casings, and a locking unit (40), which separably couples the upper and lower casings to each other.
摘要:
The present invention provides a method of cloning a protein coding for a membrane protein without the need of using anyantibody or ligand. The method of cloning a membrane protein comprises selecting a protein having a signal sequence, using a DNA coding for the signal sequence and N-terminal sequence of the protein as the reporter gene, and screening for a gene for a protein having a transmembrane domain(s). The present invention is concerned also with the CDNA obtained by using such method, a vector containing the DNA, a transformant as transformed with the vector, and the transcription product of the DNA as produced by the transformant.
摘要:
The present invention relates to a functional antibody, which specifically binds to only dermal papilla cells and dermal sheath cells and has efficacies of proliferation, survival, and activation of cells, and to a use thereof and, more specifically, to a pharmaceutical composition/cosmetic composition for preventing hair loss or promoting hair growth using the functional antibody, and to a method for preventing hair loss or promoting hair growth. It was verified that the functional antibody promotes the proliferation, survival, and activation of dermal papilla cells through cell signaling by binding with a receptor protein specifically expressed in only dermal papilla cells, thereby promoting hair growth. Therefore, the present invention can perform target therapy through a more fundamental approach in the prevention or treatment of hair loss, and is expected to also contribute to the production of cell therapeutic agents containing dermal papilla cells.
