A software application for assessing readability in the Japanese EFL context
Toshiaki Ozasa,George R. S. Weir,Masayasu Fukui
Themes in Science and Technology Education , 2010,
Abstract: We have been engaged in developing a readability index and its application software attuned for Japanese EFL learners. The index program, Ozasa-Fukui Year Level Program, Ver. 1.0, was used in developing the readability metric Ozasa-Fukui Year Level Index but tended to assume a high level of computer knowledge in its users. As a result, the application proved to be difficult to operate for ‘lay’ users. Since the majority of its expected users are not computer specialists, it is of crucial importance to develop a user-friendly program that can be used easily without any professional knowledge or skills. The goal of the present study was to provide a readability application that was informed by our index development work and sufficiently user-friendly for use by EFL professionals, i.e., Ozasa-Fukui Year Level Program, Ver. 2.0. The present paper describes the background context in which this work was undertaken and details our approach both to readability measurement and to the design of this software application for assessing readability in the Japanese EFL context.
Attention-Guided Organized Perception and Learning of Object Categories Based on Probabilistic Latent Variable Models  [PDF]
Masayasu Atsumi
Journal of Intelligent Learning Systems and Applications (JILSA) , 2013, DOI: 10.4236/jilsa.2013.52014
Abstract:

This paper proposes a probabilistic model of object category learning in conjunction with attention-guided organized perception. This model consists of a model of attention-guided organized perception of object segments on Markov random fields and a model of learning object categories based on a probabilistic latent component analysis. In attention guided organized perception, concurrent figure-ground segmentation is performed on dynamically-formed Markov random fields around salient preattentive points and co-occurring segments are grouped in the neighborhood of selective attended segments. In object category learning, a set of classes of each object category is obtained based on the probabilistic latent component analysis with the variable number of classes from bags of features of segments extracted from images which contain the categorical objects in context and an object category is represented by a composite of object classes. Through experiments using two image data sets, it is shown that the model learns a probabilistic structure of intra-categorical composition and inter-categorical difference of object categories and achieves high performance in object category recognition.

Pi Pi scattering in an effective chiral Lagrangian
Masayasu Harada
Physics , 1996,
Abstract: In this talk I summarize a recently proposed mechanism to understand pi pi scattering to 1 GeV. The model is motivated by the 1/Nc expansion to QCD, and includes a current algebra contact term and resonant pole exchanges. Chiral symmetry plays an important role in restricting the form of the interactions. The existence of a broad low energy scalar (sigma) is indicated.

Matter Field, Dark Matter and Dark Energy
Masayasu Tsuge
Physics , 2008,
Abstract: A model concerning particle theory and cosmology is proposed. Matter field, dark matter and dark energy are created by an energy flow from space to primordial matter fields at the phase transition in the early universe.
Vector Manifestation in Hot and/or Dense Matter
Masayasu Harada
Physics , 2002, DOI: 10.1143/PTPS.149.130
Abstract: In this talk I summarize main features of the vector manifestation (VM) which was recently proposed as a novel manifestation of the Wigner realization of chiral symmetry in which the symmetry is restored at the critical point by the massless degenerate pion (and its flavor partners) and the rho meson (and its flavor partners) as the chiral partner. I show how the VM is realized in hot and dense QCD using the effective field theory of QCD based on the hidden local symmetry.
New Pattern of Chiral Symmetry Restoration
Masayasu Harada
Physics , 2001,
Abstract: In this talk I summarize our recent works on the chiral symmetry restoration in the large flavor QCD using the hidden local symmetry (HLS) as an effective field theory of QCD. Bare parameters in the HLS are determined by matching the HLS with QCD at the matching scale through the Wilsoninan matching conditions. This Wilsonian matching leads to the vector manifestation of the Wigner realization of the chiral symmetry in which the symmetry is restored by the massless degenerate pion (and its flavor partners) and rho meson (and its flavor partners) as the chiral partner.
Formulation of Vector Manifestation in Hot and/or Dense Matter
Masayasu Harada
Physics , 2003, DOI: 10.1143/PTPS.153.165
Abstract: The vector manifestation (VM) was proposed as a novel manifestation of chiral symmetry in which the massless vector meson becomes the chiral partner of pion. In this write-up, I briefly summarize the following main ingredients to formulate the VM in hot and/or dense matter: Effective field theory (EFT) based on the hidden local symmetry; Wilsonian matching between the EFT and QCD; Intrinsic thermal and/or dense effects.
Chiral Perturbation in the Hidden Local Symmetry and Vector Manifestation of Chiral Symmetry
Masayasu Harada
Physics , 2001,
Abstract: In this talk I summarize our recent works on the chiral phase transition in the large flavor QCD studied by the hidden local symmetry (HLS). Bare parameters in the HLS are determined by matching the HLS with the underlying QCD at the matching scale through the Wilsonian matching. This leads to the vector manifestation of the Wigner realization of the chiral symmetry in which the symmetry is restored by the massless degenerate pion (and its flavor partners) and rho meson (and its flavor partners) as the chiral partner.

Masayasu Harada
Physics , 2001,
