Algorithms for the explicit symbolic and numeric evaluation of Jacquet’s Whittaker function for the GL(n,R) based generalized upper halfplane for n ≥ 2, and an implementation for symbolic evaluation in the Mathematica package GL(n)pack, are described. This requires a comparison of the different definitions of Whittaker function which have appeared in the literature.

Rupture of the pectoralis major is an uncommon injury that can lead to pain, loss of strength, and cosmetic deformity. The purpose of this study was to analyze the outcome of pectoralis major repairs by a single surgeon. Twenty-four patients who underwent pectoralis major repair by the senior author (M.D.L.) between May 2005 and March 2011 were retrospectively identified. Patients were assessed...

We have developed a method for answering single answer questions automatically using a collection of documents or the Internet as a source of data for the production of the answer. Examples of such questions are ‘What is the melting point of tin?’, and ‘Who wrote the novel Moby Dick?’. The approach we have adopted to the problem uses the Mikrokosmos ontology to represent knowledge about questio...

At present, various scar assessment scales are available, but not one has been shown to be reliable, consistent, feasible, and valid at the same time. Furthermore, the existing scar assessment scales appear to attach little weight to the opinion of the patient. The newly developed Patient and Observer Scar Assessment Scale consists of two numeric scales: the Patient Scar Assessment Scale (patie...

Considerable attention has been devoted to the development of feature selection algorithms for various applications in the last decade. Most of them concentrate to the single attributes. In contrast, limited research work has been devoted to determine correlated and pairwise attributes or features due to the difficulty of the problem. We present a novel feature selection algorithm for strongly ...

Currently, all search algorithms which use discretization of numeric attributes for numeric association rule mining, work in the way that the original distribution of the numeric attributes will be lost. This issue leads to loss of information, so that the association rules which are generated through this process are not precise and accurate. Based on this fact, algorithms which can natively h...

Despite major advances in the prediction of violence and risk management, risk evaluations are necessarily imperfect. This article focuses on the role of the evaluator in such assessments and addresses the consequences incurred by clinicians involved in conducting risk assessments. We discuss the risks of overpredicting and underpredicting violence with respect to how these risks can influence ...

A standard (single-column) bar chart can effectively visualize a sorted list of numeric records. However, the chart height limits the number of visible records. To show more records, the bars could be made thinner (which could hinder identifying records individually), and scrolling requires interaction to see the overview. Treemaps have been used in practice in non-hierarchical settings for den...
