It is an indirect detection.
As aid, Martiniuk et al. amply characterize this transfer of skilled labor as opposed to cash transfers in their title "Brain Gains…" Changing the present US tax code that provides indirect support of STMMs by allowing deduction of all applicable costs from taxable income could have a potential dampening effect on participation.
The internal density profile and shape of Earth is commonly studied by indirect physical methods, starting from the 1793 deduction by Cavendish that the Earth must have a dense core, based on a gravitational calculation, to the current methods which use sismic wave propagation, studies of the vibrational modes of the Earth as an elastic body, or temperature constraints.
This evidence is more indirect than transcript data and often requires a deduction of the likely structure of the genes based on weak or conflicting evidence.
Based on these results, we propose two primer pairs (534f/783r and mito1345f/mito1430r) which between them offer an indirect means of faithfully estimating bacterial abundances on plants, by deduction of the mito1345f/mito1430r-based mitochondrial count from that obtained with 534f/783r, which amplifies both bacterial and mitochondrial DNA but excludes chloroplast.
Its efforts include (but aren't limited to) bouts of easy money from the Fed, the mortgage-interest deduction, the exclusion of capital gains on primary residence sales, direct and indirect subsidies from the Department of Housing and Urban Development, and artificial liquidity pumped into the mortgage market via government sponsored entities Fannie and Freddie.
By contrast, deduction of copy number changes from ROMA and allele-specific SNP arrays depends on indirect inference from the states of neighbouring markers, and the placement of these markers is dictated not by the biological question but by their inclusion in a subgenomic representation (in ROMA) or by the existence of common SNP variation (in allele-specific analyses).
If any of the proposed changes are enacted (elimination of various deductions, treating employer health insurance as income, among others), they will represent a significant, albeit indirect, tax increase.
