PURPOSE To establish the accuracy, intra- and inter-observer variabilities of four different segmentation methods for measuring cardiac functional parameters in healthy and infarcted rat hearts. MATERIALS AND METHODS Six Wistar rats were imaged before and after myocardial infarction using an electrocardiogram and respiratory-gated spoiled gradient echo sequence. Blinded and randomized dataset...

The relationship between economic growth and environmental impact has become a recurrent subject of research in recent years. Currently, results that indicate the accumulation leads to reduction coexist with others do not show any evidence this respect. This paper aims analyse using Material Flow Analysis through two most frequent methods: territorial or production consumption. For purpose, dat...

T paper derives two mechanisms through which Bayesian-rational individuals with differing priors will tend to be relatively overconfident about their estimates and predictions, in the sense of overestimating the precision of these estimates. The intuition behind one mechanism is slightly ironic: In trying to update optimally, Bayesian agents overweight information of which they overestimate the...

Opening of ion-channels has been popularly described by means of Markov processes with a small number of important channel states. The approximation of the number of important states is often ambiguous and overestimating this number creates unnecessary computational complexities. We propose a simple equation that will portray the essence of voltage regulated ion-channel gating in a functional c...
