    In Arabidopsis, leaves and flowers form cyclically in the shoot meristem periphery and are triggered by local accumulations of the plant hormone auxin. Auxin maxima are established by the auxin efflux carrier PIN-FORMED1 ...
  • Suwa, Tomomi; Tomita, Satoshi; Hosoito, Nobuyoshi; Yanagi, Hisao (MDPI AG, 2017-10-20)
    Herein we experimentally study magnetic multilayer metamaterials with broken translational symmetry. Epitaxially-grown iron-gold (Fe-Au) multilayers modulated using Fibonacci sequence—referred to as magnetic inverse ...

    Ocular morphogenesis requires several signalling pathways controlling the expression of transcription factors and cell-cycle regulators. However, despite a well-known mechanism, the dialogue between those signals and factors ...
  • Ikegami, Daisuke; Kaji, Yuichi (Institute of Electronics, Information and Communication Engineers, 2003-03-01)
    New algorithms for the soft-derision and the hard-derision maximum likelihood decoding (MLD) for binary linear block codes are proposed. It has been widely known that both MLD can be regarded as an integer programming with ...
