This is a broad, thin, usually gray ribbon running from your motherboard (or hard disk controller if present) to your hard drive.
Consider Martin Margiela's blank white label, Stella McCartney's delicate metal chain, Peggy Jennings's bit of lace and Rick Owens's two slim, parallel gray ribbons.
And what those trails look like are gray ribbons, unfurling at great heights, as if the world were a giant, crested camel's back that—staring out over the handlebars you're about to race along.
"If this means that we're going to have Pemex management responsible for budgeting and capital expenditures, and cut the gray ribbons of control" from the Finance Ministry, it's "more important than the naming of this new board," said George Baker, director of Mexico Energy Intelligence in Houston.
Blue mesh, mFo-DFc omit map for GE (contoured at 2.5σ); blue sticks, GE; gray ribbons, RNAP backbone; green surfaces, RNAP residues at which substitutions confer GE-resistance; cyan sticks, additional RNAP residues that contact GE; gray and red sticks additional RNAP residues that coordinate Mg2+(I); violet sphere, Mg2+(I).
Structure of bacterial RNAP (gray ribbons; black circle for active-center region; violet sphere for active-center Mg2+; β' non-conserved region and σ omitted for clarity; PDB 1IW7), showing the sites of Sal-resistant substitutions (green surface; sequences from Figure 2C ; 'Sal target').
