Abstract Recent quasi-optimal error estimates for the finite element approximation of total-variation regularized minimization problems using Crouzeix–Raviart require existence a Lipschitz continuous dual solution, which is not generally given. We provide analytic proofs showing that continuity solution necessary, in general. Using truncation technique, we, addition, derive depend directly on S...

OBJECTIVE 1. To reduce errors in the ordering of total parenteral nutrition (TPN) in the Newborn Intensive Care Unit (NICU) at the Johns Hopkins Hospital (JHH). 2. To develop a pragmatic low-cost medical information system to achieve this goal. METHODS We designed an online total parenteral nutrition order entry system (TPNCalculator) using Internet technologies. Total development time was th...

This paper addresses the biometric scores fusion problem from the error rate minimization point of view. Comparing to the conventional approach which treats fusion classifier design and performance evaluation as a two-stage process, this work directly optimizes the target performance with respect to fusion classifier design. Based on a smooth approximation to the total error rate of identity ve...

Several groups have recently commented on the need for more realistic information on analytical performance of laboratory tests. The term "total analytical error" is sometimes used in this context. However, differing opinions have been expressed on how best to obtain estimates of clinical assay error, as it would be perceived by clinicians. We suggest a pragmatic definition of total analytical ...

A common hypothesis about practices to reduce survey nonresponse is that those persons brought into the respondent pool through persuasive efforts may provide data filled with measurement error. Two questions flow from this hypothesis. First, does the mean square error of a statistic increase when sample persons who are less likely to be contacted or cooperate are incorporated into the responde...
