Bronchoalveolar lavage (BAL) fluid analysis was performed to determine whether the sympathetic nervous system and T cells were key sources of catecholamines in current models of lung injury. Peak levels of adrenaline occurred in BAL fluids 2 h after the initiation of immune-complex-mediated injury (Fig. 4e).
An example to show covariance estimation with the Mahalanobis distances on Gaussian distributed data. For Gaussian distributed data, the distance of an observation to the mode of the distribution can be computed using its Mahalanobis distance: where and are the location and the covariance of the underlying Gaussian distribution. In practice, and are replaced by some estimates.
The reason for this is that the planets have elliptical orbits and none of them are perfect circles. As an example, the distance between the planet Mercury and Earth can range from 77 million km at the closest point, to as far as 222 million km at the farthest.There is a huge amount of different in the distances between the planets depending on their position on their orbit path.The table below shows the eight planets and the average distance between them. The AU column is the distance in astronomical units.1 AU is the distance from the Sun to Earth, which is 149,600,000 km.here is a huge amount of different in the distances between the planets depending on their position on their orbit path.
