"That a direct requirement for most Americans to purchase any product or services seems an intrusive exercise of legislative power," Judge Silberman wrote, "surely explains why Congress has not used this authority before — but that seems to us a political judgment rather than a recognition of constitutional limitations".
Also, let F be the matrix consisting of vector L which denote direct requirement of labour per unit of output.
Domestic direct requirement matrices for the 2009 national input output tables of China, Japan, and the U.S. were used for inter-regional comparison.
Alternatively, the relationship between ept and Dome localization could indicate a direct requirement for ept in Dome endolysosomal trafficking in much the same way that ESCRT mutants block the vesicular movement and lysosomal turnover of the Notch receptor [4] [6], [47].
Satellite cells formed in Pax7-null mice are rapidly depleted from muscle following birth [15] [17], but it is unknown whether this occurs as a result of defects acquired during development, or through a direct requirement for Pax7 postnatally.
It is possible that it is a consequence of the loss of expression of regulatory genes during hindbrain segmentation, or there might be a direct requirement for Med12 function in proliferation or in the synthesis of components of the machinery that supports DNA replication and cell division.
Third, Cdk9, being a subunit of P-TEFb, is known to phosphorylate RNAPII CTD, Spt5 C-terminal domains, and NELF, which together form protein complexes, suggesting a possible direct requirement of RNAPII or NELF phosphorylation for the manisfestation of NSpt5's effect.
Three independent lines of evidence demonstrate a direct requirement of VEGFR3 in NSC activation.
One possibility is that bps1 signal synthesis has a direct requirement for GSH.
Our results identify a direct requirement for ezrin in Src-induced VEGF-C expression in breast carcinoma cells.
The involvement of syntaxin-1/SNAP-25 acomplexesomplexes in docking suggests a direct requirement for SNAP-25 in docking, similar to syntaxin-1.
