Postprandial changes in plasma total cholesterol (TC) are minimal and there is essentially no difference between fasting vs random TC concentrations, as reflected in the small diurnal coefficient of variation (CV) for TC of 2.5%. Similarly, a cholesterol-rich meal within the last 24 hours lacked an impact on plasma TC. Thus, random specimens are acceptable in blood cholesterol screening. The in...

Despite many proposed alternatives, the predominant model in portfolio selection is still mean-variance. However, the main weakness of the mean-variance model is in the specification of the expected returns of the individual securities involved. If this process is not accurate, the allocations of capital to the different securities will in almost all certainty be incorrect. If, however, this pr...

We have searched for a light pseudoscaler particle “X(214)” which is suggested by HyperCP experiment in the K0 L → π0π0X(X → μ+μ−) decay process using the E391a detector at KEK. In our analysis, signal event “X(214)” has not observed with the 3.58 × 109 K0 L decays, and we set an upper limit for the branching fraction of K0 L → π0π0X(X → μ+μ−) to be 1.6 × 10−6 at the 90% confidence level. Also ...

From a suitable integral representation of the Laplace transform of a positive semi–definite quadratic form of independent real random variables with not necessarily identical densities a univariate integral representation is derived for the cumulative distribution function of the sample variance of i.i.d. random variables with a gamma density, supplementing former formulas of the author. Furth...
