Impedance cardiography (ICG) may be altered by noises as respiration and movement artifacts, mainly during exercise. In this work, a scaled Fourier linear combiner (SFLC) event-related to the R-R interval of ECG is proposed. It estimates the deterministic component of the impedance cardiographic signal and removes the noises uncorrelated to this interval.(More)
The effect of exercise intensity on the power spectral properties of the periodic oscillation of the skin blood flow was investigated with respect to the variability of heart rate in 7 healthy male subjects. The skin blood flow (SBF) and heart rate (HR) were measured by a laser-Doppler flowmeter on the forehead skin, and by an ECG, at rest and during(More)
Wood was treated with lasers of 349- and 355-nm wavelength and 5- and 12-ns pulse width. First, holes were drilled in the wood, and high aspect ratio holes of 20-µm diameter and 5-mm depth were obtained within several seconds at 80 mW of output. The diameter of the holes was relatively uniform in the depth direction. Incising was then conducted on the wood(More)
Cutting of wood using short-wavelength (266-, 355-, 532-, and 1064-nm) lasers was carried out and wavelength dependence in relation to machining performance and post-processing appearance was investigated. We found that a 355-nm-wavelength laser achieves the greatest machining performance. The variation in machining performance between different wavelengths(More)
We report a 73-year-old woman with myelodysplastic syndromes (MDS) of the refractory anemia with excess of blasts-1 subtype, which was diagnosed in April 2014 on the basis of cytopenia for two cell types. After completing 3cycles of azacitidine (AZA) therapy, the patient was admitted to our hospital based on an initial presentation of high fever. During(More)
A novel developed fiber-optic transmitter and receiver pairs for 622 Mbps and 2.4 Gbps transmission are presented. They operate over wide temperature range thanks to feed-forward automatic power control (APC) and phase locked loop (PLL) technology.
