Forests and woodlands cover about 20% of Earth's land surface, spanning all but the highest latitudes.
Almost the entire width of fluid compositions on the graphite-saturation surface spans a relatively small range in oxygen fugacities equivalent to CCO to IW.
Based on finite element analyses, a set of formulas for estimating the crack driving force under creep conditions in terms of the crack tip opening displacement (CTOD), δ5, which measures the CTOD at the specimen side surface, spanning the original crack tip over a gauge length of 5 mm, is presented for three fracture specimens.
Important changes in crystal structure within the mantle occur at 410 and below the surface, spanning a transition zone that separates the upper and lower mantle.
We produce a DF using thin plate spline (TPS; Bookstein, 1989), which is defined as the least-bending smooth surface spanning a set of anchor points.
In addition, glutamic acid E285 and tyrosine Y289 form a dimer surface spanning the interface and bridging the active sites between the opposite halves of each subunit, see Figure 2 (For full image, please see Additional file 1).
We focus on the analysis of geometric mathematical quantities of the MHC α-helices that allow us to characterize their shape and geometry, that is, interhelical distance and area of the ruled surface spanned by the MHC α-helices.
In addition, the findings that the linker coupling D1 and D2 is very short and that the multiple contacts between D1 and D2 could enable close coupling of the two domains suggest that the two domains, when closely packed and aligned together, could form a potential polysaccharide-binding surface spanning D1 and D2 [ 44].
The color composition of ectopic eyespots induced on wings of butterflies from concerted selection lines (Fig. 4) further suggest that the threshold response is not compartmentalized across comparable regions of a wing surface (spanning at least three wing cells) where there is clear compartmentalization of focal signaling [ 67, 68].
To obtain a measure for this helical displacement, we calculated the approximation, using a triangulation, of the area of the ruled surface spanned by the two helices of each complex: The area of I Ak amounts to 6.7255 nm and the area of I Au amounts to 6.6575 nm.
The Rayburst diameter is the diameter obtained by measuring the minimum surface-to-surface span inside a tubular structure (see Rodriguez et al. [1] for full mathematical details).
