The National Institute of Information and Communications Technology (NICT) has been conducting research and development of a third-generation airborne synthetic aperture radar (Pi-SAR X3) since 2016. Pi-SAR X3 improves the resolution (30cm) of the second-generation airborne SAR (Pi-SAR2 [1]). It can observe the Earth's surface with a resolution of 15 cm. This paper reports on the design and development status of Pi-SAR X3. In addition, The results of test observations performed to verify the operation of the instrument are reported and images obtained from the test observations are presented. In the test observation, the ground surface was observed at 15 cm and 30 cm resolution, and the advantages of the improved resolution are discussed by comparing the two images.

Hemiplegia is a disease where the sufferer has difficulties moving the muscles, and thus rehabilitation is required. We propose a method for real-time CG animation of the cooperative motion of both hands for a mirror box therapy support system in place of mirror box therapy. This system displays cooperative movement through CG. The image of a healthy hand is displayed in real-time. On the other hand, the image of a hemiplegic hand is substituted by motion capture data of the healthy hand. In this system, patients perceive the hand by replaced motion capture as their affected hand, and the brain is "tricked" into believing that it is. We use a leap motion device for motion capture and obtain the position information of the fingers. We evaluate our system by applying it to six people.

MOTIVATION: Although a huge amount of mammalian genomic data does become publicly available, there are still hurdles for biologists to overcome before such data can be fully exploited. One of the challenges for gaining biological insight from genomic data has been the inability to cross-reference transcriptomic and proteomic data using a single informational platform. To address this, we constructed an open-access database that enabled us to cross-reference transcriptomic and proteomic data obtained from immune cells. RESULTS: The database, named RefDIC (Reference genomics Database of Immune Cells), currently contains: (i) quantitative mRNA profiles for human and mouse immune cells/tissues obtained using Affymetrix GeneChip technology; (ii) quantitative protein profiles for mouse immune cells obtained using two-dimensional gel electrophoresis (2-DE) followed by image analysis and mass spectrometry and (iii) various visualization tools to cross-reference the mRNA and protein profiles of immune cells. RefDIC is the first open-access database for immunogenomics and serves as an important information-sharing platform, enabling a focused genomic approach in immunology. AVAILABILITY: All raw data and information can be accessed from http://refdic.rcai.riken.jp/. The microarray data is also available at http://cibex.nig.ac.jp/ under CIBEX accession no. CBX19, and http://www.ebi.ac.uk/pride/ under PRIDE accession numbers 2354-2378 and 2414.

This paper describes how block-coded modulation (BCM) and multiple BCM (MBCM) with Viterbi decoding can be designed for use in Rayleigh fading and severe Rician fading channels. New codes are developed by modifying known codes to increase the minimum symbol distance, which is one of the distances that has a strong effect on the bit error rate (BER) performance under fading channels. Combined with anti-fading techniques such as fading compensation, interleaving, and branch weighting, the new codes significantly improve BER performance. Computer simulations were used to confirm the code performance.

Researchers have studied two types of digital multi-carrier modulation, wavelet packet modulation (WPM), and fractal modulation. The advantage of WPM is that it allows signal time and frequency to be divided and multiplexed. Therefore the time and frequency of noise signals, e.g., tone and impulse noise, can be identified and effectively partitioned in packets. Using this advantage, we propose a class-coded modulation method for WPM that has good bit error rate (BER) performance when the length of the code constraint is extended and can select time and frequency noise signals simultaneously. This report describes the proposed method and the computer simulations carried out to test its effectiveness.

COMETS (Communications and Broadcasting Engineering Test Satellite), which was developed to evaluate Ka-band (31/21 GHz) and millimeter-wave (47/44 GHz) advanced mobile satellite communications and 21-GHz advanced satellite broadcasting systems, is presented as well as the developed ground terminals. COMETS carries an SCPC/TDM regenerative transponder for direct mobile-to-mobile communications, and IF-filterbanks for interconnection between multibeams. For mobile and personal applications, a portable terminal for regenerative transponder experiments, and several antennas such as an active phased array antenna, a waveguide slot array antenna, and a torus reflector antenna were developed. For satellite broadcasting experiments, trellis-coded modems for HDTV transmission at 60/140 Mbps and 155 Mbps were developed.
