Abstract:
A method and apparatus configures a beamforming coefficient based on the signal strength information without collecting channel information by adjusting the phase of the antennas through random perturbation. An antenna control method of a base station in a wireless communication system using a beamforming technique includes measuring nth received signal strength at nth phase of at least one receive antenna, measuring (n+1)th received signal strength at (n+1)th phase shifted randomly from the nth phase in one of forward and backward directions, and configuring a beamforming coefficient with the phase at which the received signal strength is greatest through comparison of received signal strengths. The random perturbation-based beamforming method and apparatus of the present disclosure is capable of configuring the beamforming coefficient appropriate for the normal cellular environment using a plurality analog array antenna without channel estimation overhead.
Abstract:
The present invention relates to an induced pluripotent stem cell (iPSC) model of Noonan syndrome, a preparation method thereof, and uses to study of the pathogenesis of Noonan syndrome and a therapeutic agent screening method. Particularly, induced pluripotent stem cells from dermal fibroblasts of a Noonan syndrome-patient (NS-iPSCs) were generated, and differentiated into embryoid bodies (EBs), neural rosettes and neural cells. These iPSCs exhibited the normal morphology while showed reduced differentiation potency compare to control cell lines. NS-iPSCs were developed into embryoid bodies and neural rosettes by naturally and chemically directed differentiation. Interestingly, embryoid bodies and neural rosettes induced via chemically directed differentiation exhibited normal morphology and expressed ectoderm, neural rosettes and neural marker genes similar to normal cells. Thus, the cellular model can be useful in analytical research to understand pathogenesis of Noonan syndrome and establish screening method of the therapeutic agent.
Abstract:
Sensor coupled to the ultrasound probe provides position information related to an ultrasound imaging position in the object. A processor performs first registration between the medical image and the ultrasound image based on the anatomical feature in the ultrasound image and a medical image of the object acquired by imaging modality different from the ultrasound apparatus, obtains first registration information which provides a relationship between a coordinate system of the medical image and a coordinate system of the ultrasound image based on the first registration, performs second registration between the sensor and the medical image based on the position information and the first registration information, and obtains second registration information based on the second registration. A display may display a portion of the medical image corresponding to the ultrasound imaging position based on the second registration information. The medical image includes one of SPECT, PET, MR, PET-CT, and PET-MR image.

Abstract:
Disclosed are a method of encoding a division block in video encoding and a method of decoding a division block in video decoding. An input picture is divided into encoding unit blocks. The encoding unit blocks are divided into sub-blocks. The sub-blocks are encoded by selectively using at least one of intra prediction encoding and inter prediction encoding. A decoding process is performed through a reverse process of the encoding method. When pixel values of an encoding unit block are encoded in video encoding, the flexibility in selecting an encoding mode is increased and the efficiency of encoding is increased.
