Ho:YAG single crystal fiber: fabrication and optical characterization Report Title 0.5% Holmium (Ho) doped YAG single crystal fiber (SCF) was fabricated using Laser Heated Pedestal Growth (LHPG) method and characterized for its optical absorption and emission properties involving transitions between the 5I8 and 5I7 energy levels. The results verified the absorption peaks suitable for in-band di...

In 1963 Rubinstein and Taybi described a new syndrome characterized by broad thumbs and toes, facial abnormalities and mental retardation. The syndrome can be observed in the neonatal period by typical thumbs, halluces and facial abnormalities. The prevalence in the general population is unknown, however the disorder is not rare and is present in about 1:600 patients in mental retardation clini...

This contribution addresses filtering requirements to meet the ETSI and ANSI specifications on transmit signal power spectral density (PSD) for VDSL systems employing multicarrier modulation techniques. It is shown that the specifications can be met with simple fixed filtering elements. Conformance with the various PSD masks is achieved by proper adjustment of the digital gains at the input of ...

In analyses of bivariate ordered polytomous cataract data from atomic-bomb survivors, we compared two methods, the univariate worse-eye method, and the bivariate generalized estimating equations (GEE’s) method using global odds ratio by Williamson et al. (Journal of the American Statistical Association, 90, 1432–1437, 1995).When the association was large and only subject level covariates were u...

The simultaneous determination of financial default and political crises is studied in an open economy model. Political crises accompany default in equilibrium because of an information transmission conflict between the government and the public. Multiple equilibria are possible: if foreign lenders are pessimistic about the country’s stability, they demand a high interest on the debt, exacerbat...
