    The arctic is a sensitive system undergoing dramatic changes related to recent warming trends. Vegetation dynamics - increases in the quantity of green vegetation and a northward migration of trees into the arctic tundra - are a component of this change. Although field studies over long time periods can be logistically problematic, simulation modeling provides a means for projecting changes in arc... View full abstract»

    Much of the difficulty in learning advanced concepts in quantum mechanics comes from trying to visualize abstract problems. This article addresses the situation with interactive curricular material created as part of the open source physics project. In particular, the authors focus on the measurement and time evolution of two-state superpositions in the context of bound states and spin. View full abstract»

    This paper discusses a new Bayesian-analysis-based region-growing algorithm for medical image segmentation that can robustly and effectively segment medical images. Specifically the approach studies homogeneity criterion parameters in a local neighbor region. Using the multislices Gaussian and anisotropic filters as a preprocess helps reduce an image's noise. The algorithm framework is tested on C... View full abstract»

    To gain performance, developers often build scientific applications in procedural languages, such as C or Fortran, which unfortunately reduces flexibility. To address this imbalance, the authors present CompuCell3D, a multitiered, flexible, and scalable problem-solving environment for morphogenesis simulations that's written in C++ using object-oriented design patterns.

  • Gauss-Vaníček and Fourier Transform Spectral Analyses of Marine Diversity

    This article shows that Gauss-Vanick (GV) analysis of this diversity data detrended with a cubic also strongly signals a 62-million-year periodicity. Furthermore, it was found that neither GV analysis nor Fourier transform analysis of the nondetrended data leads to any statistically significant periodicity. The results show that the two techniques are equivalent. View full abstract»

    Among many computer scientists, fortran is an f-word. yet, it's still the most widely used language in scientific computing, especially when high performance is required. why is this so? One explanation often given is the huge amount of scientific legacy code in the world-after all, differential equations remain the same over time and so do their solvers, so there's no reason to rewrite such code....

    The cluster design rules (CDR) helps inexperienced users focus on the most important factors in cluster design. Without it, users must rely on a "cookie cutter" approach that can result in giving up performance unnecessarily. To really determine which cluster design will be best for a particular application, the designer must know what the application does and which hardware architecture will best... View full abstract»

    The authors present a robust and fast loop-detection strategy to interactively place dense, uncluttered, evenly spaced streamlines, which help visualize complex flows. Although loop detection is critical to streamline placement, few researchers have addressed this issue. In this paper an effective, robust, and fast loop-detection strategy for creating evenly spaced streamlines is described. At a n... View full abstract»

    Students need self-assessment skills, yet in our experience, these skills appear to be severely lacking in undergraduate students. Descriptions from student interviews and related education research results suggest ways to increase students' ability to self-assess. Grading students' projects on how they form links to analytical solutions or physical situations will communicate the importance of se... View full abstract»
