Individual particles in an urban airshed can contain both primary and secondary components, and the composition of ambient aerosols have been found to reflect source PM emission characteristics differences over space (e.g., between cities) and time (e.g., across seasons) (e.g., Spengler and Thurston 1983).

While the principle components of these inclusions, such as TDP-43, FUS (Kwiatkowski et al., 2009; Vance et al., 2009), and dipeptide repeat proteins (Mori et al., 2013) are known, determination of the secondary components of the inclusions could shed light on disease etiology.

For the decoding at PR at the end of the second phase, MRC is performed to decode x p by utilizing the received signals in two successive phases, i.e., y p (1) and y p (2), while treating the secondary component of x s simply as noise.
Owing to the relatively small dimensions compared to the main bridge components (girders, piers, abutments, piles), shear keys are normally regarded as secondary component of a bridge structure, and their influences on bridge seismic responses are normally neglected.
Although the primary direction of sand transport was along the elongated crests of the bedforms, a secondary component of transverse motion enabled the lateral migration and preferential preservation of lee-slope deposits that arose from a minor oblique component of bedform migration.
