The GBPZ-T40-xHo (x=0, 2, 4, 6, 8 and 10 mol%) Faraday glasses doped with various concentrations of Ho3+ ions were prepared, the structure, physical properties and various incident wavelengths and temperature on the values of Verdet constant of GBPZ-T40-xHo Faraday glass system are studied, it...

This paper develops linear estimators for structural and causal parameters in nonparametric,nonseparable models using panel data. These models incorporate unobserved, time-varying, individual heterogeneity, which may be correlated with the regressors. Estimation is based on an approximation of...
