Infants' speech perception abilities change through the first year of life, from broad sensitivity to a wide range of speech contrasts to becoming more finely attuned to their native language. What remains unclear, however, is how this perceptual change relates to brain responses to native language contrasts in terms of the functional specialization of the(More)
The present study using near-infrared spectroscopy examined the neuronal correlates of Japanese long/short vowel contrast discrimination and its relationship with behavioral performance by comparing native Japanese (L1) subjects and Korean subjects learning Japanese as a second language (L2). Phoneme-specific responses were predominantly observed in the(More)
Fructans are water-soluble fructose oligomers and polymers that are based on sucrose, and have been implicated in protecting plants against water stress. Rice (Oryza sativa L.) is highly sensitive to chilling temperatures, and is not able to synthesize fructans. Two wheat fructan-synthesizing enzymes, sucrose:sucrose 1-fructosyltransferase, encoded by wft2,(More)
In this paper, we propose a robust method to register a panoramic range data obtained by a panoramic laser range finder and an omni-directional image acquired by a stereo omni-directional system (SOS), by matching the horizontal and vertical edge histograms of the two images. The proposed method first estimates the relative horizontal rotation angle by(More)
LOTOS is a formal specification language, designed for the precise description of open distributed systems and protocols. Our purpose is to introduce the operators of logics (for example, disjunction, conjunction, greatest fixpoint, least fixpoint in µ-calculus) into (basic) LOTOS, in order to describe flexible specifications. Disjunction operators ∨ have(More)
In this paper we propose a process algebra, CCSG, in which we can approximately analyze processes by neglecting unimportant distant actions. Although many kinds of process algebra have already been proposed, there is a common problem that the number of feasible action sequences explosively increases with the number of concurrent processes. Therefore, an(More)
