Backscattering ratios of soot-contaminated dusts at triple LiDAR wavelengths: T-matrix results
Abstract:
This paper reports on accurate calculations of backscattering properties of transported and soot-contaminated dust at triple wavelengths (0.355, 0.532, and 1.064 μm, respectively) by using the invariant imbedding T-matrix method. The changes of backscattering ratios from bare to soot-contaminated dust were systematically investigated by employing super-spheroidal dust and fractal soot models. The impacts of morphology change and soot absorptivity on backscattering ratios of soot-contaminated dust were clarified. In addition, it was found that adhesion has a large impact on the backscattering ratios. However, the results of non-contact soot-contaminated dust appear to be closer to observations than those of contact mixing.

The Extracellular Matrix
In order to maintain tissue organization, many animal cells are surrounded by structural molecules that make up the extracellular matrix (ECM). Together, the molecules in the ECM maintain the structural integrity of tissue as well as the remarkable specific properties of certain tissues.
