    As an essential step for brain morphogenesis, neurons migrate via mechanical interactions with components of their environment such as neighboring cells and the extracellular matrix. However, the molecular mechanism by ...
  • Sensing of substratum rigidity and directional migration by fast-crawling cells 
    Okimura, Chika; Sakumura, Yuichi; Shimabukuro, Katsuya; Iwadate, Yoshiaki (American Physical Society, 2018-05-03)
    Living cells sense the mechanical properties of their surrounding environment and respond accordingly. Crawling cells detect the rigidity of their substratum and migrate in certain directions. They can be classified into ...
  • Identification of depression subtypes and relevant brain regions using a data-driven approach

    It is well known that depressive disorder is heterogeneous, yet little is known about its neurophysiological subtypes. In the present study, we identified neurophysiological subtypes of depression related to specific neural ...
  • Gradient-reading and mechano-effector machinery for netrin-1-induced axon guidance

    Growth cones navigate axonal projection in response to guidance cues. However, it is unclear how they can decide the migratory direction by transducing the local spatial cues into protrusive forces. Here we show that ...
  • Smart Contract-Based Access Control for the Internet of Things 
    Zhang, Yuanyu; Kasahara, Shoji; Shen, Yulong; Jiang, Xiaohong; Wan, Jianxiong (IEEE, 2018-06-15)
    This paper investigates a critical access control issue in the Internet of Things (IoT). In particular, we propose a smart contract-based framework, which consists of multiple access control contracts (ACCs), one judge ...
  • AutoSort：レガシーシステム分析のためのプログラミング言語の判定支援手法 
    Okada, Joji; Ishio, Takashi; Sakata, Yuji; Inoue, Katsuro (情報処理学会, 2018-06-15)
    レガシーなメインフレームシステムには，拡張子が存在せずプログラミング言語が不明なソースコードファイルが多数存在する．レガシーシステムを分析する際には各ソースコードファイルのプログラミング言語を判定する必要があるが，これを手作業で行うと多大な労力が必要となってしまう．本研究ではプログラミング言語の判定作業を支援するために，手作業で判定すべきファイルの代表をクラスタリングによって選出する手法を提案する．正確な判定を支援するため，提案手法はパ ...
  • Targeted delivery of fluorogenic peptide aptamers into live microalgae by femtosecond laser photoporation at single-cell resolution
