e s (i, j ) (E S (i, j ), respectively) is the free energy (normalized energy, respectively) of the stack with exterior pair (i, j ) and interior pair (i + 1, j − 1).
e B (i, j, i ′, j ′) (E B (i, j, i ′, j ′), respectively) is the free energy (normalized energy, respectively) of the bulge or internal loop with exterior pair (i, j ) and interior pair (i', j' ).
The set of base pairs on R[ i, j] consists of all interior pairs R p R q with i ≤ p < q ≤ j and all exterior pairs R p S h with i ≤ p ≤ j.
Importantly, the alignment A and the structures S and T are not independent of each other: Sankoff requires that all external base pairs and interior base pairs of multiloops of both RNAs are covered by (S, T, A ).
But some of the most successful solutions involve dividing the interior with a pair of opposing bookcases set at right angles to the walls.
It's also much improved, shedding roughly 270 pounds and gaining a handsome Sonata-style interior and a pair of direct-injection 4-cylinder engines.
Within the interior of "Bunker" is a pair of headphones, which emit a loud, screeching noise.
Winter may finally have thawed, sending us warily out into the scattered sunlight, but this week's DVD slate is an unseasonably interior affair – led by a pair of literal chamber pieces.
Given secondary structure S, an external base pair is a base pair (i, j) ∈ S, which is not interior to any other base pair of S; i.e. there is no (x, y) ∈ S with the property that x < i < j < y.
When he returned home, he ran a pair of restaurants and worked as an interior designer.
