CONTEXT The effectiveness of the long-term monitoring of errors detected by frozen section-permanent section correlation is unknown. OBJECTIVE To determine factors important in laboratory improvement in frozen section-permanent section discordant and deferral rates by participation in a multi-institutional continuous quality improvement program. DESIGN Participants in the College of America...

ing the behaviours of separate actions into a single composite action allows groups of actions to be coordinated instead of multiple individual actions. Returning to the example in section 4.1, this can be done by time-slicing the plan into subplans with homogenous states. These sub-plans are formalized by conjunctions of a temporal constraint, action states, and action superposition applied to...

We consider multilevel Toeplitz matrices Tn(f) generated by Lebesgue integrable functionsf defined over I, I = [−π, π), d ≥ 1. We are interested in the solution of linear systems withcoefficient matrix Tn(f) when the size of Tn(f) is large. Therefore the use of iterative methodsis recommended for computational and numerical stability reasons. In this note we focus ourattenti...

Correction It has been brought to our attention that there is an error in the estimated time of occurrence of horizontal transfers in the Drosophila genome in our article [1]. The twelfth paragraph of the Results and discussion section should read: The distributions of Ks values among the littlediverged TEs display a peak within the range 0.03-0.05 (Figure 3). If we assume a mutational clock of...
