This paper presents a new algorithm for correcting incorrect line drawings—incorrect projections of a polyhedral scene. Such incorrect drawings arise, e.g., when an image of a polyhedral world is taken, the edges and vertices are extracted, and a drawing is synthesized. Along the way, the true positions of the vertices in the 2D projection are perturbed due to digitization errors and the prepro...

The ability to calculate drug dosages correctly is an essential skill for registered nurses to possess. Performing drug calculations accurately is not a skill that new graduates have the luxury of developing over time. Drug errors are in many instances directly related to either the administration of an incorrect dose or incorrect infusion rate caused by calculation errors. A strategy for imple...

TP53 mutations in the absence of 17p-deletion correlate with rapid disease progression and poor survival in chronic lymphocytic leukemia (CLL). Herein, we determined the TP53 mutation frequency in 268 newly diagnosed CLL patients from a population-based material. Overall, we detected TP53 mutations in 3.7% of patients (n = 10), where 7/10 cases showed a concomitant 17p-deletion, confirming the ...

Undergraduate MS business students developed and debugged a spreadsheet modelfrom a wordproblem. This model consisted ofa bid to build a wall. The problem was designed to be relatively simple and domain-free, to address the concern that past spreadsheet experiments mqv have usedproblems that were too dtflcult or that required domain knowledge that subjects did not have. During the development p...

A new form of consider covariance analysis suitable for application to square-root information filters with a wide variety of model errors is presented and demonstrated. A special system formulation is employed, and the analysis draws on the algorithms of square-root information filtering to provide generality and compactness. This analysis enables one to investigate the estimation errors that ...

BACKGROUND As one of the several effective solutions for personal privacy protection, a global unique identifier (GUID) is linked with hash codes that are generated from combinations of personally identifiable information (PII) by a one-way hash algorithm. On the GUID server, no PII is permitted to be stored, and only GUID and hash codes are allowed. The quality of PII entry is critical to the ...

Not only committing errors, but also observing errors has been shown to activate the dorsal medial prefrontal cortex, particularly BA 8 and adjacent rostral cingulate zone (RCZ). Currently, there is a debate on whether this activity reflects a response to the incorrectness of the committed action or to its unexpectedness. This article reports two studies investigating whether activity in BA 8/R...

Statistically consistent estimation of phylogenetic trees or gene trees is possible if pairwise sequence dissimilarities can be converted to a set of distances that are proportional to the true evolutionary distances. Susko et al. (2004) reported some strikingly broad results about the forms of inconsistency in tree estimation that can arise if corrected distances are not proportional to the tr...
