Minteer, Shelley D. | Controlled placement of enzymes on carbon nanotubes using comb-branched DNA | Immobilization is not only useful for preserving enzyme activity, but also to adhere an enzyme to a surface, such as an electrode, so that the enzyme does not leach into solution during testing. Current immobilization approaches do not readily allow for adjustments to the distance between the enzyme... | 2014-01-01 | |

Wen, Ming | Correlates of leisure-time physical activity participation among Latino children and adolescents with acanthosis nigricans | Childhood obesity has become a serious public health concern in the United States. The prevalence rates of childhood obesity largely increased in the 1980s and 1990s and remained persistently high between 1999-2000 and 2007-2008 in the United States [20]. The highest extreme obesity prevalence rate,... | 2014-01-01 | |

Francis, Leslie | Creation Ethics and the harms of existence | David DeGrazia's Creation Ethics1 is a fascinating effort to present a consistent account of creation in many contexts-from reproduction, to self-creation through genetic enhancement, to the creation of entire future generations. For reasons of space, this comment addresses the related discussions o... | 2014-01-01 | |

Whitaker, Ross T. | Curve boxplot: Generalization of boxplot for ensembles of curves | In simulation science, computational scientists often study the behavior of their simulations by repeated solutions with variations in parameters and/or boundary values or initial conditions. Through such simulation ensembles, one can try to understand or quantify the variability or uncertainty in a... | 2014-01-01 | |

Clayton, Dale H. | Darwins finches combat introduced nest parasites with fumigated cotton | Introduced parasites are a threat to biodiversity when naïve hosts lack effective defenses against such parasites [1]. Several parasites have recently colonized the Galápagos Islands, threatening native bird populations [2]. For example, the introduced parasitic nest fly Philornis downsi (Diptera:... | 2014-01-01 | |

Adler, Frederick R. | Deconvolution of isotope signals from bundles of multiple hairs | Segmental analysis of hair has been used in diverse fields ranging from forensics to ecology to measure the concentration of substances such as drugs and isotopes. Multiple hairs are typically combined into a bundle for segmental analysis to obtain a high-resolution series of measurements. Individua... | 2014-01-01 | |

Bargteil, Adam Wade | Deformation embedding for point-based elastoplastic simulation | We present a straightforward, easy-to-implement, point-based approach for animating elastoplastic materials. The core idea of our approach is the introduction of embedded space-the least-squares best fit of the material's rest state into three dimensions. Nearest neighbor queries in the embedded spa... | 2014-01-01 | |

Meyer, Miriah Dawn | Design activity framework for visualization design | An important aspect in visualization design is the connection between what a designer does and the decisions the designer makes. Existing design process models, however, do not explicitly link back to models for visualization design decisions. We bridge this gap by introducing the design activity fr... | 2014-01-01 | |

Lundahl, Brad Ward | Different histories, different stories: using a narrative tool to assess childrens internal worlds | This study investigated the concurrent validity of a children's narrative assessment tool, the Plenk Story-Telling Test (PST). The PST attempts to measure aspects of young children's internal working models by eliciting narratives from nine pictures. The PST, Child Behavior Checklist, and the Parent... | 2014-01-01 | |

Zick, Cathleen D. | Does daylight savings time encourage physical activity? | Background: Extending Daylight Savings Time (DST) has been identified as a policy intervention that may encourage physical activity. However, there has been little research on the question of if DST encourages adults to be more physically active. Methods: Data from residents of Arizona, Colorado, Ne... | 2014-01-01 | |

Riloff, Ellen M. | Domain-specific coreference resolution with lexicalized features | Most coreference resolvers rely heavily on string matching, syntactic properties, and semantic attributes of words, but they lack the ability to make decisions based on individual words. In this paper, we explore the benefits of lexicalized features in the setting of domain-specific coreference reso... | 2014-01-01 | |

Gerig, Guido | DTIPrep: quality control of diffusion-weighted images | In the last decade, diffusion MRI (dMRI) studies of the human and animal brain have been used to investigate a multitude of pathologies and drug-related effects in neuroscience research. Study after study identifies white matter (WM) degeneration as a crucial biomaker for all these diseases. The too... | 2014-01-01 | |

Bargteil, Adam Wade | Dynamic sprites | Traditional methods for creating dynamic objects and characters from static drawings involve careful tweaking of animation curves and/or simulation parameters. Sprite sheets offer a more drawing-centric solution, but they do not encode timing information or the logic that determines how objects shou... | 2014-01-01 | |

Chapman, Kathy L. | Early lexical characteristics of toddlers with cleft lip and palate | Main Outcome Measures: The groups were compared for size of expressive lexicon reported on the MacArthur Communicative Development Inventory and the percentage of words beginning with obstruents and sonorants produced in a language sample. Differences between groups in the percentage of word initial... | 2014-01-01 | |

Bowling, David R. | Ecological processes dominate the 13C land disequilibrium in a Rocky Mountain subalpine forest | Fossil fuel combustion has increased atmospheric CO2 by ≈ 115 μmol mol1 since 1750 and decreased its carbon isotope composition (δ13C) by 1.7-2‰(the 13C Suess effect). Because carbon is stored in the terrestrial biosphere for decades and longer, the δ13C of CO2 released by terrestrial ecosyst... | 2014-01-01 | |

Hughes, Kelly T. | The effect of cell growth phase on the regulatory cross-talk between flagellar and Spi1 virulence gene expression | The flagellar regulon controls Salmonella biofilm formation, virulence gene expression and the production of the major surface antigen present on the cell surface: flagellin. At the top of a flagellar regulatory hierarchy is the master operon, flhDC, which encodes the FlhD4C2 transcriptional complex... | 2014-01-01 | |

Askew, Eldon W | Effect of leucine supplementation on fat free mass with prolonged hypoxic exposure during a 13-day trek to Everest Base Camp: A double-blind randomized study | Loss of body weight and fat free mass (FFM) are commonly noted with prolonged exposure to hypobaric hypoxia. Recent evidence suggests protein supplementation, specifically leucine, may potentially attenuate loss of FFM in subcaloric conditions during normoxia. The purpose of this study was to determ... | 2014-01-01 | |

Newton, Maria | Effects of a classroom-based physical activity program on childrens physical activity levels | High levels of physical inactivity are evident among many American children. To address this problem, providing physical activity (PA) during the school day within the CSPAP framework, is one strategy to increase children's PA. Thus, the purpose of this study was to examine the effects of a classroo... | 2014-01-01 | |

Forster, Richard R. | Effects of bedrock lithology and subglacial till on the motion of Ruth Glacier, Alaska, deduced from five pulses from 1973 to 2012 | A pulse is a type of unstable glacier flow intermediate between normal flow and surging. Using Landsat MSS, TM and ETM+ imagery and feature-tracking software, a time series of mostly annual velocity maps from 1973 to 2012 was produced that reveals five pulses of Ruth Glacier, Alaska. Peaks in ice ve... | 2014-01-01 | |
