Supervised artificial neural networks are used to predict useful properties of galaxies in the Sloan Digital Sky Survey, in this instance morphological classifications, spectral types and redshifts. By giving the trained networks unseen data, it is found that correlations between predicted and actual properties are around 0.9 with rms errors of order ten(More)
In mammals, pregnancy has very interesting interaction between the maternal uterus and the fetus. For maternal immune system, fetus is recognized as semiallograft. However the maternal immune cells do not attack and reject a fetus during a pregnant period. The reason why that immune tolerance is established in the maternal decidua is the specific area(More)
The extracorporeal shock wave lithotripsy (ESWL) has come into wide use due to its non-invasive advantage. However, as for the shock wave propagation in human body in relation to practical lithotripsy, there are a few studies on numerical simulation based on models conforming to practical situations. In this paper we report a numerical method of finite(More)
