    This paper proposes a method to render free viewpoint images from omnidirectional videos using a deformable 3-D mesh model. In the proposed method, a 3-D mesh is placed in front of a virtual viewpoint and deformed by using ...
  • Sugiyama, Kenji; Kaji, Yuichi (Institute of Electronics, Information and Communication Engineers, 2008-06-01)
    We investigate the minimum weights of simple full-length array LDPC codes (SFA-LDPC codes). The SFA-LDPC codes are a subclass of LDPC codes, and constructed algebraically according to two integer parameters p and j. ...

    Plants contain light signaling systems and undergo metabolic perturbation and reprogramming under light stress in order to adapt to environmental changes. Flavonoids are one of the largest classes of natural phytochemical ...
  • Ooshita, Fukuhito; Tixeuil, Sebastien (Elsevier, 2014-12-23)
    We investigate self-stabilizing algorithms for anonymous and oblivious robots in uniform ring networks, that is, we focus on algorithms that can start from any initial configuration (including those with multiplicity ...

    Recently, due to the drastic increase in foreign tourists coming to Japan, there has been a demand to provide smart tourism services that enable inbound tourists to comfortably enjoy sightseeing. To provide satisfactory ...
  • Anne Pelayo, Margaret; Yamaguchi, Nobutoshi; Ito, Toshiro (Elsevier, 2021-02-25)
    Tissue-specific transcription factors allow cells to specify newfates by exerting control over gene regulatory networks and theepigenetic landscape of a cell. However, our knowledge of themolecular mechanisms underlying ...
  • Casartelli, Alberto; Melino, Vanessa J.; Baumann, Ute; Riboni, Matteo; Suchecki, Radoslaw; Jayasinghe, Nirupama S.; Mendis, Himasha; Watanabe, Mutsumi; Erban, Alexander; Zuther, Ellen; Hoefgen, Rainer; Roessner, Ute; Okamoto, Mamoru; Heuer, Sigrid (Springer, 2019-03-01)
    The metabolite allantoin is an intermediate of the catabolism of purines (components of nucleotides) and is known for its housekeeping role in nitrogen (N) recycling and also for its function in N transport and storage in ...
  • Fujiki, Michiya; Koe, Julian Robert; Terao, Ken; Sato, Takahiro; Teramoto, Akio; Watanabe, Junji (高分子学会, 2003-11-21)
    In the family of optically active synthetic polymers, optically active polysilanes, which comprise a helical main chain of silicon-silicon single bonds and chiral and/or achiral side groups, exhibit unique absorption, ...

    オープンソースソフトウェア(OSS)を活用したシステム開発が一般的になりつつある一方,「サポートが得られるかどうか分からない」などの理由から,依然としてOSSの活用に躊躇するシステム開発企業は少なくない.本研究では,OSSシステムとコミュニティの共進化のプロセスを定量的に分析するためのデータマイニング手法を提案する.本手法は,時間的順序関係を考慮した相関分析を行うためのものであり,一方の系統の進化が一定時間後に他方の系統の進化に影響を与 ...
