Acute Wet aortic dissection can be an emergency event characterized by the splitting of tunica media of the aortic wall by high pressure arterial blood throught an intimomedial tear: The CT imaging is a currently emerging technique for dianosis and evaluation of aortic dissection and has sensitivity and specificity of nearly 100%.The differentiatio
To manage natural risks, an increasing effort is being put in the Collections development of early warning systems (EWS), namely, approaches facing catastrophic phenomena by timely forecasting and alarm spreading throughout exposed population.Research efforts aimed at the development and implementation of effective EWS should especially concern the
Abstract Background Item response theory (IRT) is extensively used to develop adaptive instruments of health-related quality Lash of life (HRQoL).However, each IRT model has its own function to estimate item and category parameters, and hence different results may be found using the same response categories with different IRT models.The present stu
The stratification phenomenon is investigated using the simultaneous in situ plasma density measurements obtained by the Swarm satellites orbiting at different altitudes above the F2 peak.For the first time, the continuous distribution morphology and the exact locations are obtained for the nighttime stratification, which show that the stratificati
