  • Tomita, Satoshi; Kurosawa, Hiroyuki; Ueda, Tetsuya; Sawada, Kei (IOP Publishing, 2018-02-06)
    This review introduces and overviews electromagnetism in structured metamaterials which undergo simultaneous time-reversal and space-inversion symmetry breaking due to magnetism and chirality. Direct experimental observation ...
  • Kashiwabara, Yuki; Ishio, Takashi; Hata, Hideaki; Inoue, Katsuro (電子情報通信学会, 2015-03-01)
    It is well-known that program readability is important for maintenance tasks. Method names are important identifiers for program readability because they are used for understanding the behavior of methods without reading ...
  • Tomita, Satoshi; Sawada, Kei; Nagai, Shotaro; Sanada, Atsushi; Hisamoto, Nobuyuki; Ueda, Tetsuya (American Physical Society, 2017-10-13)
    This study observes microwave beam splitting dependent on circular polarizations through nonuniform chiral metamaterials. Nonuniform chiral metamaterials with a gradation in refractive index are constructed using chiral ...

    We investigate the microwave spectroscopies of a micrometer-sized single permalloy (Py) chiral structure on coplanar waveguides (CPWs). Under an external dc magnetic field applied in a direction perpendicular to the microwave ...
  • Matsuura, Satoshi; Fujikawa, Kazutoshi; Sunahara, Hideki (Institute of Electronics, Information and Communication Engineers, 2007-10-01)
    With the rapid rise in the demand for location related service, communication devices such as PDAs or cellar phones must be able to search and manage information related to the geographical location. To leverage location-related ...
  • Fujiki, Michiya (MDPI, 2010-08-13)
    From elemental particles to human beings, matter is dissymmetric with respect to mirror symmetry. In 1860, Pasteur conjectured that biomolecular handedness? homochirality?may originate from certain inherent dissymmetric ...
  • Fujiki, Michiya (日本化学会, 2009-11-24)
    From elemental particles to human beings, matter and living worlds ill our universe are dissymmetric with respect to mirror symmetry. Since the early 19th century, the origin of biomolecular handedness has been puzzling ...
  • Okura, Fumio; Kanbara, Masayuki; Yokoya, Naokazu (ACM, 2015-03-05)
    This article describes a Mixed-Reality (MR) application that superimposes lost buildings of a historical site onto real scenes virtualized using spherical aerial images. The proposed application is set at a UNESCO World ...

    MLLRと多数話者データベースを用いたHMM音響モデルの教師なし環境雑音適応アルゴリズムを提案する.対象話者の任意の1文発声と居室雑音を入力として音声データベースから環境適応用雑音重畳データを生成することで,話者に負担をかけずに大量の適応用データを得ることができる.具体的な適応処理は以下の3段階からなる.(1)GMMを用いた話者識別を用いて,入力話者と音響的距離の近い話者をデータベースから選択する.(2)(1)の選択話者の読み上げ音声を ...
  • Yano, Keisuke; Katsuki, Hiroyuki; Yanagi, Hisao (American Institute of Physics, 2019-02-06)
    Organic molecular crystals have a variety of low frequency vibrational modes composed of intra- and inter-molecular oscillations. They are mixed intricately in the terahertz (THz) region. We are interested in the controllability ...
  • Okubo-Kurihara, Emiko; Ohtani, Misato; Kurihara, Yukio; Kakegawa, Koichi; Kobayashi, Megumi; Nagata, Noriko; Komatsu, Takanori; Kikuchi, Jun; Cutler, Sean; Demura, Taku; Matsui, Minami (Macmillan Publishers Limited, part of Springer Nature, 2016-10-03)
    The cell wall is one major determinant of plant cell morphology, and is an attractive bioresource. Here, we report a novel strategy to modify plant cell wall property by small molecules. Lasalocid sodium (LS) was isolated ...
  • Takahashi, Isao; Kuroiwa, Shigeki; Lindfors, Hanna E.; Ndamba, Lionel A.; Hiruma, Yoshitaka; Yajima, Tatsuo; Okishio, Nobuyuki; Ubbink, Marcellus; Hirota, Shun (John Wiley & Sons, Ltd., 2009-04-20)
    To photomodulate the interaction of the phosphatidylinositol 3-kinase SH3 domain with a peptide ligand, a cyclic peptide (cyclic-1) with a photolabile side chain-to-side chain linker was synthesized. The conformation of ...
  • Hirota, Shun; Kawahara, Takumi; Beltramini, Mariano; Di Muro, Paolo; Magliozzo, Richard S.; Peisach, Jack; Powers, Linda S.; Tanaka, Naoki; Nagao, Satoshi; Bubacco, Luigi (The American Society for Biochemistry and Molecular Biology, Inc., 2008-11-14)
    Flash photolysis and K-edge x-ray absorption spectroscopy (XAS) were used to investigate the functional and structural effects of pH on the oxygen affinity of three homologous arthropod hemocyanins (Hcs). Flash photolysis ...
  • Ojetunde, Babatunde; Shibata, Naoki; Gao, Juntao (Information Processing Society of Japan, 2018-02-15)
    Secure communications is essential in many areas such as disaster management and battlefield communications. To detect and prevent attacks in such applications, most existing protocols adopt a cryptography-based approach, ...
  • Okuyama-Uchimura, Fumi; Komai, Shoji (SAGE Publications, 2015-11-02)
    In contrast to the previously held notion that mice have a weak visual system, it is now generally accepted that mice can perceive rather complicated figures in various contexts such as in cognitive experiments and in ...
