A trust game is a two-player game in extended form. The sub game perfect equilibrium of the game is that a player called an investor does not invest the wealth. Because, this behavior is the best response of the investor according to the best respons

Glasses of the Bi 2 O 3 –TeO 2 –B 2 O 3 ternary system were developed and their linear and nonlinear optical properties were investigated. The absorption edges of these glasses were found to be 367–384 nm with a good transmittance in visible wa

Nonlinear coefficient and group-velocity-dispersion of bismuth-based nonlinear fibers were determined by four-wave-mixing measurements. The wavelength dependence of refractive index of bulk bismuth-based glasses was also measured to estimate the mate
