The transcription factor Bcl11b/Ctip2 plays critical roles in the development of several systems and organs, including the immune system, CNS, skin, and teeth. Here, we show that Bcl11b/Ctip2 is highly expressed in the developing vomeronasal system in mice and is required for its proper development. Bcl11b/Ctip2 is expressed in postmitotic vomeronasal… (More)
—This paper presents a 60-GHz direct-conversion RF front-end and baseband transceiver including analog and digital circuitry for PHY functions. The 65-nm CMOS front-end consumes 319 and 223 mW in transmitting and receiving mode, respectively. It is capable of more than 7-Gb/s 16QAM wireless communication for every channel of the 60-GHz standards, which can… (More)
This paper presents a 60-GHz direct-conversion transceiver in 65 nm CMOS technology. By the proposed gain peaking technique, this transceiver realizes good gain flatness and is capable of more than 7 Gbps in 16QAM wireless communication for all channels of IEEE802.11ad standard within EVM of around -23 dB. The transceiver consumes 319mWin transmitting and… (More)
— This paper presents a 16QAM direct-conversion transceiver in 65 nm CMOS, which is capable of 60-GHz wireless standards. The capacitive cross-coupling neutralization contributes a high common-mode rejection and a high reverse isolation, and a fully-balanced mixer can improve the error vector magnitude due to the reduced local leakage. The maximum data… (More)
The purpose of this research is to develop a mechanism which assists the wheelchair user to climb a step. We design the wheelchair caster unit which has a assistive mechanism. This unit is easily replaced with a conventional wheelchair caster, thus it has an advantage for general use. In order to assist the wheelchair user to climb a step, the caster unit… (More)
The main olfactory epithelium (MOE) in mammals is a specialized organ to detect odorous molecules in the external environment. The MOE consists of four types of cells: olfactory sensory neurons, supporting cells, basal cells, and microvillous cells. Among these, development and function of microvillous cells remain largely unknown. Recent studies have shown… (More)
Ultrashort pulse oscillation of 65-fs was obtained directly from a laser-diode pumped Kerr-lens mode-locked Yb∶YAG laser with an intracavity nonlinear medium. The pulse-width is shorter than the fourier transform limit by the fluorescence of Yb∶YAG.
