Abstract

In this paper, we propose a new concept and fabrication process for magnetic disks with embedded servo patterns, named ESPAR. A servo pattern for phase detection consisting of straight lines is formed by photolithography. The disk has a flat and smooth surface for proximity recording. Servo layer thickness and recording layer thickness can be designed independently. We fabricated the disk and demonstrated the demodulation of the servo signal.

J., Nooruzzaman, Md, and Morioka, Toshio

Abstract

We demonstrate the first crosstalk-aware traffic engineering as a use case in a multicore fibre transport network. With the help of a software-defined network controller, modulation format and channel route are adaptively changed using programmable devices with XT monitors.

Abstract

We demonstrate the first 1-Pb/s unidirectional inline-amplified transmission over 205.6-km of single-mode 32-core fiber within C-band only. 96-Gbaud LDPC-coded PDM-16QAM channels with FEC redundancy of 12.75% realize high-aggregate spectral efficiency of 217.6 b/s/Hz

63. 32-core inline multicore fiber amplifier for dense space division multiplexed transmission system

Author

Jain, S., Mizuno, T., Jung, Y., Kang, Q., Hayes, J., Petrovich, M., Bai, G., Ono, H., Shibahara, K., Sano, A., Isoda, A., Miyamoto, Y., Sasaki, Y., Amma, Y., Takenagga, K., Aikawa, K., Castro, C., Pulverer, K., Nooruzzaman, Md, Torioka, T., Alam, S.U., and Richardson, D.J.

Abstract

We present a high-core-count SDM amplifier, i.e. 32-core multicore-fiber amplifier, in a cladding-pumped configuration. An average gain of 17dB and NF of 7dB is obtained for -5dBm input signal power in the wavelength range 1544nm-1564nm.

Abstract

目的．細胞膜水輸送チャネルとして発見されたアクアポリンaquaporin（AQP）にがんの発生や進展に関わる新規機能の存在が近年提唱された．本稿では多様な肺腺癌亜型におけるAQPの発現と進展への関与に関する知見を紹介する．結果．肺癌ではAQP1，3，4，5が腺癌細胞に発現する．その発現は，1）細胞分化に相当する極性を有するAQP1，3の発現，2）極性は保たれるが正常肺では認められないAQP5の異所性発現，3）極性を喪失したAQP1，5の過剰発現に区分される．1）は細気管支肺胞上皮癌に高頻度で，進展に伴い減少する．2）は肺胞上皮癌のみならず異型腺腫様過形成でも見られ，腫瘍発生に関係していると考えられる．3）は微小浸潤部から観察され始め，進展とともに頻度を増し，生命予後と有意な関連を示す．AQP1は浸潤先進部での発現亢進と浸潤部lamellipodia細胞膜での発現を介した，AQP5は細胞増殖や上皮間質移行関連分子の活性化を介した肺腺癌の浸潤・転移能亢進への関与が示唆されている．AQP5の発現と粘液産生性肺癌の進展，AQP1の過剰発現と微小乳頭状成分の侵襲性との関連性も認められる．また，AQP4は肺腺癌で発現レベルが高く，生命予後良好因子となる．結論．AQP1，5は肺腺癌の進展に関わる重要分子の一つと考えられ，新たな進展阻止法の確立のための標的分子となる可能性が示唆される．

66. Developing an SDR Test Collection from Japanese Lecture Audio Data

Author

Abstract

APSIPA ASC 2009: Asia-Pacific Signal and Information Processing Association, 2009 Annual Summit and Conference. 4-7 October 2009. Sapporo, Japan. Oral session: Initiatives in Spoken Document Processing (6 October 2009)., The lecture is one of the most valuable genres of audiovisual data. However, spoken lectures are difficult to reuse because browsing and efficient searching within spoken lectures is difficult. To promote the research activities in the spoken lecture retrieval, this paper reports a test collection for its evaluation. The test collection consists of the target spoken documents of about 2,700 lectures (604 hours) taken from the Corpus of Spontaneous Japanese (CSJ), 39 retrieval queries, the relevant passages in the target documents for each query, and the automatic transcription of the target speech data. We report the retrieval performance targeting the constructed test collection by applying a standard spoken document retrieval (SDR) method, which serves as a baseline for the forthcoming SDR studies using the test collection. We also introduce the several studies conducted by the users of the test collection.
