The products are stereoisomers — molecules that contain the same set of atoms connected identically in two dimensions, but arranged differently in three dimensions.
b, Once a substrate molecule has been loaded onto the assembler and 'primed' to undergo reactions, the machine can assemble four stereoisomers of a compound in a multistep process; stereoisomers are molecules that contain the same set of atoms connected identically in two dimensions, but that are arranged differently in three dimensions.
Whilst the weight of the caissons on the bearings is generally sufficient to rotate them, a gearing mechanism using three large identically sized gears connected by two smaller ones ensures that they turn at precisely the correct speed and remain correctly balanced.
The second class of edges connects identically labeled nodes.
This group arrangement connects identically coloured tiles in a vertical zigzag direction exactly in the 'opposite direction' to the previously seen (near-horizontal) diverging/converging mortar groupings.
Specifically, the random fluxes along edges connecting identically labeled states are replaced by the mean fluxes along those edges, while the random fluxes associated with edges connecting distinguishable states are left unchanged.
Now there is an antiderivative L of (h'/h) on U. The product (h z) exp (-L z))) is constant since it has derivative identically equal to 0 and U is connected.
Mr. van Beirendonck took stripes and cotton checks, even a pattern that looked suspiciously as though it were copied from a baby's crib bunting, and layered them, piling shirt upon identically cut shirt until, indeed, the finished garment (its layers connected only by tiny metal rods that stood up at the shoulders) seemed to praise the process of dressing itself.
The displacement amplitude is approximated by means of a superposition of simple polynomial co-ordinate functions, which satisfy identically the boundary conditions at the outer edge only and which yield excellent accuracy in the case of simply connected circular plates.
Similarly, PRR7 and PRR9 are two similar genes, modelled as if behaving identically in other work [ 20]; the algorithm connects these genes throughout each iteration of network expansion, consistent with their similar expression patterns but with each gene showing different connections to other genes of the network.
