Under Standard conditions (problems S1 S8 in Fig. 1), which were identical to the training conditions for the "on problem" in cotton-top tamarins (Hauser et al. 1999), there were pairs of sheets of the same (problems S1 S4) or different (problems S5 S8) lengths.
The active absorber is made of a pair of piezoelectric sheets, attached to both sides of the plate, and closed electric circuits.
This structurally-simple ββα domain is stabilized by hydrophobic interactions and the chelation of single zinc ion between a pair of cysteines from the β-sheet and a pair of histidines from α-helix [6].
Unfortunately, the earpieces are hard metal plates that bear inward on your head like a pair of magnetic cookie sheets.
For flows with more severe separation, the free shear layers bounding the separated wake are modelled as a pair of free vortex sheets [5], the geometries of which are iteratively determined according to the induced velocities.
The bilayer unit cell can be described as a Cd2+ ion lattice sandwiched between a pair of negatively charged sheets, consisting of [C20]− and [MS]− anions with their CH3− and COO− groups directed toward the outer and inner directions, respectively [16].
Models of aggregates equivalent to a pair of interdigitating β-sheets of eight β-strands were therefore built in silico for fibrils with class 7 and 8 architectures with the nonphosphorylated peptide (control; Figure 7), assuming an antiparallel shifted β-strand organisation within each β-sheet.
Each Fynomer is composed of a pair of anti-parallel beta sheets joined by two flexible loops which are the sites of ligand binding (Schlatter et al., 2012) (Fig. 1D).
All three domains D2, D3 and D4 are structurally homologous to each other, consisting of a pair of four-stranded β-sheets forming a β-sandwich configuration.
The core structure of PH domain consists of a pair of nearly orthogonal β-sheets of four and three antiparallel β-strands (β1 β2 β3 β4 and β5 β6 β7; Supplementary Figure 1).
The RMET consists of a series of 36 sheets with a pair of eyes printed in the middle of each sheet.
