We report highly efficient blue-light generation by frequency doubling of a high-frequency superimposed laser diode, stabilized by a grating feedback technique, in a periodically domain-inverted LiTaO(3) waveguide. To increase second-harmonic generat

Accurate measurement of large step heights using multiple-wavelength holographic interferometry is realized using laser diodes. Due to the high-resolution wavelength tunability of such lasers, a pair of holograms with a wavelength difference of less

Background: We previously reported the arterial elasticity value we measured to reflect the characteristic features of vessel walls, and to possibly be useful for detecting early stage atherosclerosis in type 2 diabetes. Obesity, especially visceral

Here we present multiple-wavelength digital holographic interferometry with a wide measurement range using laser diodes. Small wavelength differences can be easily realized by the wavelength tuning of laser diodes with injection current controls. A c

Effects of acute portal hypertension on systemic hemodynamics after hepatectomy were evaluated by portal venous stenosis (PVS) model in dogs. In protocol 1, portal hypertension of about twice portal venous pressure (PVP) decreased cardiac output (CO)

Proceedings of the 19th International Symposium on Power Semiconductor Devices and IC's.
Normally-off power MOSFET with low Rons has been developed. IEMOSFET on 4H-SiC carbon-face wafer exhibits an extremely low Rons of 1.8 mOmegacm2 with a blocking voltage of 660 V. The effective channel mobility of this device is 90 cm2/Vs which corres

A case of ductal carcinomain situ (DCIS) that was treated by partial mastectomy is reported. The operation was performed after accurate estimation of cancer spread by three-dimensional computed tomography (3D-CT). The patient was a 39-year-old woman

7th International Conference on Automatic Face and Gesture Recognition (FGR06).
This paper introduces a new representation of hand motions for tracking and recognizing hand-finger gestures in an image sequence. A human hand has 15 joints and its high dimensionality makes it difficult to model hand motions. To make things easier,
