Objectives: The aims of this study were to: (1) determine the prevalence of undernutrition and frailty in hospitalised elderly patients and (2) evaluate the efficacy of both the Mini-Nutritional Assessment (MNA) screening tool and the MNA short form (MNA-SF) in identifying frailty. Setting and Participants: A convenient sample of 100 consecutive patients (75.0 % female) admitted to the Geriatri...

The Fractional Chapman Kolmogorov Equation

The Chapman–Kolmogorov equation with fractional integrals is derived. An integral of fractional order is considered as an approximation of the integral on fractal. Fractional integrals can be used to describe the fractal media. Using fractional integrals, the fractional generalization of the Chapman–Kolmogorov equation is obtained. From the fractional Chapman–Kolmogorov equation, the Fokker–Pla...

Response to Landis and Chapman (2011).

Congratulations to the authors for their concise summary of the flaws, frailties, and limitations of ANOVA-based toxicity metrics. Having made similar calls for a transition to model-based inference, I am naturally fully supportive of the Landis and Chapman ‘‘fatwa’’ on bankrupt statistical methods in ecotoxicology. This timely article should, and no doubt will, generate much discussion among e...
