When a nucleosome is remodeled by ISW1a (left), nucleosome repositioning is blocked by a bound TF, the TF remains intact, and the remodeled nucleosome is positioned with the TF acting as a boundary and reference point.
ERC is specially designed with asymmetric boundaries and auxiliary reference, ensuring that the control error evolves within a prespecified tube (a shrinked funnel region, achieving even better tracking performance).
▪ The parameter D ¯ offset,which measures the distance between the detected boundary and the reference boundary, is computed as D ¯ offset = ∑ i = 1 N b f dist x b i, y b i N b (12).
Taking t i 1 , t i 2 and t j 1 , t j 2 as the boundaries of the test and reference labels, as indicated in Figure 3, they overlap if t i2 > t j1 or t j2 > t i1 and then the total time of the labels is T = max ( t i 2, t j 2 ) − min ( t i 1, t j 1 ) = T 1 + T 2 + T OV (1).
Births were assigned to the six county districts (average population in 1981, 79 450 (Opcs, 1983)) using digitised boundaries and the grid-reference of the postcode centroid (Local Government Act, 1972; Gregory and Southall, 1998), excluding 652 (0.7%) births for which the mother's address was missing.
The errors can be produced in two ways: first, a classification error due to a bad labeled frame, and a segmentation error due to a temporal mismatch between the reference boundaries and the hypothesis boundaries.
Grafts were placed at different antero-posterior levels in wing buds, using somites and somite boundaries as reference points [33 (Figure 5A,C insets)] and the subsequent contribution to the digits was assessed in 10 day wings ( Figure 5C).
In this case the only essential condition would be the same initial water saturation, pore structure, and boundary condition between the original and reference porous systems.
At the second occasion, a set of untreated field boundaries (reference boundaries) in the vicinity of each experiment was examined for comparison.
Different algorithms and parameter settings can be compared by ranking computed disparities between maps of computer-generated region boundaries and region boundaries from a common reference.
