BACKGROUND The aim of this study was to assess the sigmoid line of elasticity in the human aorta. METHODS AND RESULTS The pressure-diameter relation was measured in the descending aorta in 120 subjects. In an additional group of 6 subjects, transient vena caval occlusion produced 5 sets of pressure-diameter data. We found that the best fit curve of the pooled pressure-diameter data was a thir...

Abstract We study the effect of an asset’s volatility on expected returns European options asset. Deriving predictions from a stochastic discount factor model, we show that depends whether variations in are driven by systematic or idiosyncratic volatility. While idiosyncratic-volatility-induced only affect option elasticity, systematic-volatility-induced also oppositely return Since asset (elas...

Prediction of hypertensive disease in pregnancy remains challenging. Risk factor based screening utilizing history, physical characteristics, uterine artery Doppler and serum markers have been used with varying success. As hypertension in pregnancy appears to be associated with changes in the maternal vasculature, we have investigated the utility of maternal arterial elasticity measurement, pri...

BACKGROUND Exposure to risk factors in childhood may have long-term influences on vascular function. We examined the relationship between risk factors identified in childhood and arterial elasticity assessed in adulthood. METHODS AND RESULTS Carotid artery compliance (CAC), Young's elastic modulus (YEM), and stiffness index (SI), 3 measures of large-artery elasticity, were assessed with nonin...

Fine-grained elasticity control of cloud services has to deal with multiple elasticity perspectives (quality, cost, and resources). We propose a cloud services elasticity control mechanism that considers the service structure for controlling the cloud service elasticity at multiple levels, by firstly defining an abstract composition model for cloud services and enabling multi-level elasticity c...

Abstract This study aims to determine the supply factor of chili, dominant factor, and elasticity in Indonesian research location. Multiple linear regression was used analyze data. The results showed that variable number chili production previous year area t significantly affected Indonesia. In contrast, price urea fertilizer had no significant effect. A is chili. value short long term on inela...

one of the main principles of resistance economy, is to support domestic production and limiting imports, especially in sectors where there is the possibility of import-substituting production .this requires adjustment of exact trade policies,and to achieve this, identifying the structure of imports demand function and also price and income elasticity of import demand is necessary.this necessit...

A key challenge in stem cell research is to learn how to direct the differentiation of stem cells toward specific fates. In this issue of Cell, Engler et al. (2006) identify a new factor regulating stem cell fate: the elasticity of the matrix microenvironment. By changing the stiffness of the substrate, human mesenchymal stem cells could be directed along neuronal, muscle, or bone lineages.
