In an attempt to clarify the function of the suboccipital muscles, we performed morphological observation of the suboccipital muscles for variations in the muscle belly and compared the morphology of their muscle fibers in terms of cross-sectional area by immunostaining with anti-myosin heavy chain antibodies. The cadavers of 25 Japanese individuals were used: 22 for morphological examinations ...

As distance education rapidly appears on the horizon, distance learning technologies are becoming more important in delivering contents and allowing collaboration between students and teachers in globally disparate environments. One of the recent innovative technologies to be explored in distance learning field is immersive environments and sense of presence that offers. The primary purpose of ...

Understanding the conditions under which Virtual Environment (VE) users experience a sense of presence may, in the long term, yield valuable insights into human cognition and psychology. More immediately, however, the general assumption is that a sense of presence impacts a user’s ability to perform a task and, therefore, that insights into presence offer a potential payoff in terms of task per...

3-D sound field reproduction systems can provide listeners with a sense of presence. In this study, we have proposed the 3-D sound field localization system using parametric loudspeakers. This system can easily represent sound images on the wall by using parametric loudspeakers that have a high directivity. In contrast, it is difficult to reproduce reverberant environments such as a concert hal...

Simultaneous anomalous change of geoelectric field was observed on January 17, 1999 at three far-distant stations in Nagano Prefecture, Japan. Eleven days after the anomalous change, an earthquake swarm with a M4.8 main shock started at a location within the triangle formed by the three stations. This change was rectangular in shape like the VAN-type anomalous change in Greece. The anomaly coul...
