In this paper asymptotic confidence intervals for the Sortino and Omega Ratio are proposed and analyzed. First the confidence intervals are derived under the strong assumption of temporal independence and identical distribution of the returns. Later they are obtained assuming that the process followed by returns is strictly stationary and α-mixing of a certain size. In order to evaluate the min...

A balanced omega-6/omega-3 polyunsaturated fatty acid (PUFA) ratio has been linked to health benefits and the prevention of many chronic diseases. Current dietary intervention studies with different sources of omega-3 fatty acids (omega-3) lack appropriate control diets and carry many other confounding factors derived from genetic and environmental variability. In our study, we used the fat-1 t...

A weakly nonlinear oscillator of natural frequency omega(0) and damping ratio delta is driven by an amplitude-modulated force of dimensionless amplitude epsilon, carrier frequency omega, and modulation frequency omega(1). Each of (omega - omega(0))/omega(0), omega(1)/omega(0), and delta is O(epsilon(2/3)) as epsilon --> 0. The response in this resonant neighborhood is a slowly modulated sine wa...

BACKGROUND & AIMS Omega 3 and omega 6 polyunsaturated fatty acids have been related to many diseases, especially to cardiovascular diseases. We aimed to assess the association between the intake of omega 3, omega 6 fatty acids and their ratio and the incidence of glaucoma in this prospective cohort study. METHODS We followed-up 17,128 participants initially free of glaucoma for a median time ...

BACKGROUND Physical exercise and healthy dietary habits are recommended to prevent breast cancer. DISCUSSION Increased intake of omega-3 fatty acids associated with decreased omega-6 - resulting in higher omega-3 to omega-6 ratio compared with Western-type diet - is inversely associated with breast cancer risk. The modernized Mediterranean diet with high omega-3 to omega-6 ratio, high fiber a...

one-hundred-sixty-eight 28-wk-old hy-line layers (w-36) were used to evaluate the effect of different levels of linseed (ls) and safflower seed (ss) on antibody titter, blood and yolk cholesterol, yolk fatty acid content and the ratio of omega-6/ omega-3. hens were randomly assaigned in a compeletly randomised design each 3 replicates of 8 hens. they were fed diets contained 0, 4, 7 and 10% ls ...

BACKGROUND This research was conducted to explore the relationships between the levels of omega-3 fatty acids in serum phospholipid and key fatty acid ratios including potential cut-offs for risk factor assessment with respect to coronary heart disease and fatal ischemic heart disease. METHODS Blood samples (n = 2053) were obtained from free-living subjects in North America and processed for ...

The ratio of omega-3 to omega-6 fatty acids, especially the long-chain eicosapentaenoic acid (EPA) + docosahexaenoic acid (DHA) to arachidonic acid (AA) ratio, is inversely associated with breast cancer risk. We measured the association between cytologic atypia, a biomarker for short-term risk of breast cancer development, and omega-3 and omega-6 fatty acid intake and levels in blood and breast...
