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 mean distance is about 150 million kilometers or 93 million miles the semi major axis is me asured as 149598261 kilometers perihelion when the earth is the closest to the sun occurs around the first week or januraryt our closest point to the sun called perihelion about january 4 it s about 91500000 miles and at the farthest point aphelion around july 2 it s about 94500000 miles the distance of the earth from the sun is roughly 93 million miles
