Females who are affected by fragile X syndrome (FXS) can have significant physical, neuropsychological and emotional involvement. This study was designed to explore the relationships between these three domains and to learn how the degree of involvement in each of these phenotypic areas relates to molecular parameters including CGG repeat length and(More)
Fragile X syndrome is the most common from of inherited mental retardation. Approximately half of females with the full mutation have significant cognitive deficits, whereas females with the premutation do not. Phenotypic effects seen in 281 females (IQs from 64 to 139) were analyzed. Results showed that females with the full mutation differ significantly(More)
In this paper, we consider multivariate interpolation with radial basis functions of finite smoothness. In particular, we show that interpolants by radial basis functions in ℝ with finite smoothness of even order converge to a polyharmonic spline interpolant as the scale parameter of the radial basis functions goes to zero, i.e., the radial basis functions(More)
