This demonstration shows a city-planning system based on augmented reality with tangible interface. Miniature models, illustrations and graphical computer displays have been used for the comparison and consideration in city-planning process. Augmented reality technology enables users to consider of city plans more effectively and easily. One important issue(More)
Angiofibroma of soft tissue is a recently described soft tissue tumor that is characterized by fibroblastic spindle tumor cells with arborizing capillary proliferation. Cytogenetically, it harbors a specific fusion gene involving the nuclear receptor coactivator 2 (NCOA2) gene. We report here additional new pathological and cytogenetic features. A soft(More)
The kinds of change in facial expression which can be produced by a sender's neural control of facial muscles, and, at the same time, can be visually perceived by a listener are described in discrete symbols. The linguistic information supplemented by the facial expressions in signing is categorized into syllabic, lexical and syntactic components. In order(More)
Resolution of the fundamental frequency of speech sound required for the design of a speech processor of a cochlear implant device is investigated, with special regard to transmitting voice pitch information in Asian languages. Clinical application of the cochlear implant has spread rapidly in recent years to Asian countries where a variety of languages(More)
A multi-purpose symbolic system which can describe all of the mouth shapes conveying various kinds of linguistic information in signing, speech dialogue, and speechreading is developed, taking account of the constraints of anatomical structure and neural control and the possibility of visual discrimination. In order to make the changes in the(More)
An inhibitor of the complex of factor VIIa and tissue factor (fVIIa/TF), 2-substituted-4-amidinophenylpyruvic acid 1a, was structurally modified with the aim of increasing its potency and selectivity. The lead compound 1a was originally found in our factor Xa (fXa) inhibitor library on the basis of structural similarity of the primary binding sites of fVIIa(More)
An inhibitor of factor Xa (fXa), the m-substituted benzamidine AXC1578 (1a), was structurally modified with the aim of increasing its potency. In particular, pyruvic acid and propionic acid substituents were incorporated into the P1 benzamidine moiety to introduce a favorable interaction with the oxy-anion hole in the catalytic triad region of fXa.
