(11)C-methionine (Met) positron emission tomography (PET) is one of the most commonly used PET tracers for evaluating brain tumors. However, few reports have described tips and pitfalls of (11)C-Met PET for general practitioners. Physiological (11)C-Met uptake, anatomical variations, vascular disorders, non-tumorous lesions such as inflammation or dysplasia, benign brain tumors and patient cond...

Simulation modeling is a tool commonly used in support of intelligent decision making by senior managers, particularly for extremely complex problems. This article uses an example from the United States Army Recruiting Command to illustrate some of the statistical pitfalls an analyst may encounter when using simulation modeling. These pitfalls include conflicting results, both due to different ...

-Recently, we have introduced the first version of ACOPIN, an Ant Colony Optimization (ACO) algorithm for clustering proteins in the protein interaction network (PIN). Based on the experimental results, we have discovered serious pitfalls; very difficult to define the boundaries among clusters and unable to identify the overlapping clusters. These pitfalls contribute to low accuracy of detected...

The most common statistical pitfalls in ecological research are those associated with data exploration, the logic of sampling and design, and the interpretation of statistical results. Although one can find published errors in calculations, the majority of statistical pitfalls result from incorrect logic or interpretation despite correct numerical calculations. There are often simple solutions ...
