Artificial Neural Network (ANN) is a flexible and popular tool for predicting the non-linear behavior in the environmental system. Here, the feed-forward ANN model was used to investigate the relationship among the land use, fertilizer, and hydrometerological conditions in 59 river basins over Japan and then applied to estimate the monthly river total(More)
The measurement of spatially distributed water surface elevation (WSE) at the global scale, which is planned by " Surface Water and Ocean Topography (SWOT) mission " , will bring lots of fresh knowledge on global-scale terrestrial water circulation especially when observed WSE is merged into global hydrodynamics modes by data assimilation. In this paper, we(More)
The cosmological magnetic field is one of the important physical quantities which affect strongly the cosmic microwave background (CMB) power spectrum. Recent CMB observations have been extended to higher multipoles l 1000, and they resultantly exhibit an excess power than the standard model prediction in cosmological theory which best fits the Wilkinson(More)
The primordial magnetic field (PMF) can strongly affect the cosmic microwave background (CMB) power spectrum and the formation of large scale structure. In this presentation, we calculate the CMB temperature anisotropies generated by including a power-law magnetic field at the photon last scattering surface (PLSS). We then deduce an upper limit on the(More)
Placing constraints on the neutrino mass is an important goal in modern physics. One important limit on the neutrino mass can be deduced from the cosmological constraint on the formation of large scale structure as the neutrinos become nonrelativistic at late times. On the other hand we have shown that the development of large scale structure and the limits(More)
A 82-year-old man was referred to our hospital with a chief complaint of macrohematuria and pollakisuria. Cystoscopy showed an abnormal mucosa on the right wall. We suspected carcinoma in situ but two months after cystoscopy showed a non-papillary and sessile tumor with calcification. We performed transurethral resection of the bladder tumor, muscle layer(More)
Local wet etching technique was proposed to fabricate high-performance aspherical mirrors. In this process, only the limited area facing to the small nozzle is removed by etching on objective surface. The desired objective shape is deterministically fabricated by performing the numerically controlled scanning of the nozzle head. Using the technique, a(More)
