LIZ-FACTORIZATION OF OPERATORS ON lx

Necessary and sufficent conditions are obtained for ¿(/-factorization of operators on /,. In particular it is shown that uniform invertibility of the compressions of the operator is not sufficient to insure an LU-factorization of the operator, thus answering a question of de Boor, Jia, and Pinkus. The question of when a bounded linear operator on lp, 1 < p <, oo, has an Li/-factorization has be...

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...

Liz Rhoades: Single molecules tell many stories

R ecent advances in lasers and fl uo-rescent dyes have made it possible to observe individual proteins as they fold into their mature conforma-tion or bind to other proteins. Liz Rhoades is harnessing these techniques to answer questions about the biology of amyloid family proteins—whose aggregation is associated with neurodegenerative syndromes such as Parkinson's and Alzheim-er's disease (1)....
