INTRODUCTION Syncope is a common problem and can lead to serious consequences in the elderly. Tilt test is useful to investigate recurrent syncope, but few studies have investigated the hemodynamic responses of this population to tilt test. OBJECTIVE To describe the tilt test responses of elderly patients with recurrent syncope of unknown origin and to determine the occurrence of altered card...

PURPOSE To report a novel method for measuring the vertical tilt angle of the optic nerve (ON) head and to investigate the associated factors. DESIGN Cross-sectional diagnostic study. METHODS One hundred and twelve normal, glaucomatous, and glaucoma suspect eyes (99 patients) were enrolled in this study. Subjects underwent a full eye examination, biometry, and spectral-domain optical cohere...

Abs t rac t In this paper, we will propose a new method for object tracking, which is primarily based on the results from prof. Shinagawa's iniage matching. We will provide a method that tracks an object and follows it in real-time throagh a sequence of images which are given, for example, by a robotic camera. The main feature of the method is that it is not affected by the movements (within a ...

CONTEXT The age at sexual debut is declining in China, but little is known about the relationship between the social and demographic characteristics of Chinese youth and the timing of debut. METHODS Data were drawn from the 2009 National Youth Reproductive Health Survey, which collected background information and age at sexual debut from 22,300 unmarried youth aged 15-24. Life table analysis ...

This study was conducted to compare the effectiveness of the traditional method of ankle bandaging and the new method of ankle taping for judo athletes in Japan, and to introduce a functionally effective taping method for judo players. Four university judo athletes with ankle instability were selected to undertake radiography of the ankles before and after exercise, with bandaging at one time a...

OBJECTIVES This study was conducted to develop a time-efficient tilt table test. BACKGROUND Current protocols of tilt table testing are quite time-consuming. This study was designed to assess the diagnostic value, tolerance and procedural time of a single-stage isoproterenol tilt table protocol. METHODS A single-stage isoproterenol tilt table test was compared with the passive tilt table te...

Choosing the appropriate type of video input is an important issue for any vision-based system and the right decision must take into account the specific requirements of the intended application. In the context of Intelligent Room systems, we establish several qualitative criteria to evaluate the video input component and we use them to compare three current solutions: mobile pan-tilt-zoom came...

A stationary stimulus is perceived to drift in the opposite direction after adaptation to a moving stimulus (static motion aftereffect (MAE)). It is commonly assumed that positional effects from the static motion aftereffect are mediated by early visual areas. Here we psychophysically showed that these positional effects did not modulate illusory line-tilt aftereffect (TAE). Since illusory cont...
