Root, Root Hair, and Symbiotic Mutants of the Model Legume Lotus japonicus
Autor: Masayoshi Kawaguchi, Haruko Imaizumi-Anraku, Hiroyuki Koiwa, Sinobu Niwa, Akira Ikuta, Kunihiko Syono, Shoichiro Akao
Publikováno v: Molecular Plant-Microbe Interactions, Vol 15, Iss 1, Pp 17-26 (2002)
To gain an overview of plant factors controlling nodule number and organogenesis, an extensive screening using model legume Lotus japonicus was carried out. This screening involved 40,000 M2 seeds, and 32 stable mutant lines were isolated. From these

Responses of a Model Legume Lotus japonicus to Lipochitin Oligosaccharide Nodulation Factors Purified from Mesorhizobium loti JRL501
Autor: Shinobu Niwa, Masayoshi Kawaguchi, Haruko Imaizumi-Anraku, Svetlana A. Chechetka, Masumi Ishizaka, Akira Ikuta, Hiroshi Kouchi
Publikováno v: Molecular Plant-Microbe Interactions, Vol 14, Iss 7, Pp 848-856 (2001)
Lotus japonicus has been proposed as a model legume for molecular genetic studies of symbiotic plant-microbe interactions leading to the fixation of atmospheric nitrogen. Lipochitin oligosaccharides (LCOs), or Nod factors, were isolated from the cult

State Estimation for Sound Environment System with Nonlinear Observation Characteristics by Introducing Wide-Sense Particle Filter
Autor: Akira Ikuta, Hisako Orimoto, Kouji Hasegawa
Publikováno v: Intelligent Information Management. 11:87-101
In this study, a modified particle filter considering non-Gaussian properties of noises is proposed in a form applicable to real situation in sound environment system where the observation data are contaminated by the external noise (i.e., background

Noise suppression method by jointly using bone- and air-conducted speech signals
Autor: Gerard Gallagher, Akira Ikuta, Hisako Orimoto
Publikováno v: Noise Control Engineering Journal. 66:472-488
When applying speech recognition to actual circumstances such as inspection and maintenance operations in industrial factories to recording and reporting routines at construction sites where handwriting is difficult, some countermeasure methods for s

A Bayesian Filter for Sound Environment System with Quantized Observation*
Autor: Akira Ikuta, Hisako Orimoto
Publikováno v: Intelligent Information Management. 10:87-98
In the real sound environment, the observation data are usually contaminated by additional background noise of arbitrary distribution type. In order to estimate several evaluation quantities for specific signal based on the observed noisy data, it is

State Estimation for Fuzzy Sound Environment System with Finite Amplitude Fluctuation
Autor: Akira Ikuta, Gerard Gallagher, Hisako Orimoto
Publikováno v: Journal of Software Engineering and Applications. 10:625-638
Internal physical mechanism of actual sound environment system is often difficult to recognize analytically, and it contains unknown structural characteristics. Furthermore, the observation data often contain fuzziness due to several causes and exhib
