BACKGROUND To investigate the relationship between baseline systolic blood pressure (SBP) and visit-to-visit blood pressure variability in a general population. METHODS This is a prospective longitudinal cohort study on cardiovascular risk factors and cardiovascular or cerebrovascular events. Study participants attended a face-to-face interview every 2 years. Blood pressure variability was de...

Abstract. Let dμ be a probability measure on the unit circle and dν be the measure formed by adding a pure point to dμ. We give a simple formula for the Verblunsky coefficients of dν based on a result of Simon. Then we consider dμ0, a probability measure on the unit circle with l Verblunsky coefficients (αn(dμ0)) ∞ n=0 of bounded variation. We insert m pure points to dμ, rescale, and form the p...

The investment evaluation of power grid construction projects is a necessary link for companies to carry out construction. In the traditional process, it generally based on original index scores or similar schemes comparison and decision-making. There are problems simple methods insufficient theoretical support. Fully considering various factors in process construction, set rating system with t...

Description This function calculates the coefficient of variation for each gene in the qPCR experiment, and returns the average coefficient of variation across all genes.

Description This function calculates the coefficient of variation for each gene in the qPCR experiment, and returns the average coefficient of variation across all genes.

The coefficient of the variation function is a useful descriptive statistic, especially when comparing variability more than two curve groups, even they have significantly different mean curves. Since ratio and standard deviation functions, its particular property that it shows acceleration explicitly function. aim study twofold: to show functional sensitive abrupt changes propose utilisation a...
