 | Pascucci, Valerio | Combining in-situ and in-transit processing to enable extreme-scale scientific analysis | With the onset of extreme-scale computing, I/O constraints make it increasingly difficult for scientists to save a sufficient amount of raw simulation data to persistent storage. One potential solution is to change the data analysis pipeline from a post-process centric to a concurrent approach based... | 2012-01-01 | |

 | Saam, Brian | Comment on pressure dependence of wall relaxation in polarized 3He gaseous cells | Zheng et al. [Zheng, Gao, Ye, and Zhang, Phys. Rev. A 83, 061401(R) (2011)] have measured a strong linear pressure dependence of the nuclear relaxation rate of 3He in glass cells typically used to generate and/or store polarized 3He at room and cryogenic temperatures. Their interpretation is that th... | 2012-01-01 | |

 | Bisson, Erica F. | Computed tomography-based determination of a safe trajectory for placement of transarticular facet screws in the subaxial cervical spine: Clinical article | Object. Placement of transarticular facet screws is one option for stabilization of the subaxial cervical spine. Small clinical series and biomechanical data support their role as a substitute for other posterior stabilization techniques; however, the application of transarticular facet screws in th... | 2012-01-01 | |

 | Pascucci, Valerio | Computing morse-smale complexes with accurate geometry | Topological techniques have proven highly successful in analyzing and visualizing scientific data. As a result, significant efforts have been made to compute structures like the Morse-Smale complex as robustly and efficiently as possible. However, the resulting algorithms, while topologically consis... | 2012-01-01 | |

 | Battin, Margaret P. | Continuous sedation until death: moral justifications of physicians and nurses─a content analysis of opinion pieces | Continuous Sedation until Death (CSD), the act of reducing or removing the consciousness of an incurably ill patient until death, often provokes medical-ethical discussions in the opinion sections of medical and nursing journals. A content analysis of opinion pieces in medical and nursing literature... | 2012-01-01 | |

 | Sekercioglu, Cagan | Correlates of elevational specialisation in Southeast Asian tropical birds | The understanding of elevational selectivity in extremely rich tropical biotas is critical to the study of accelerating human-mediated environmental changes (e.g., deforestation and global climate warming). This paper explores the characteristics of Southeast Asian birds that are altitudinal special... | 2012-01-01 | |

 | Bisson, Erica F. | Cost effectiveness of subaxial fusion-lateral mass screws versus transarticular facet screws | As health care reform continues to evolve, demonstrating the cost effectiveness of spinal fusion procedures will be of critical value. Posterior subaxial cervical fusion with lateral mass screw and rod instrumentation is a wellestablished fixation technique. Subaxial transarticular facet fixation is... | 2012-01-01 | |

 | Murphy, Patricia A. | Criterion-based screening for sexually transmitted infection: sensitivity, specificity, and predictive values of commonly used questions | Background: Practice protocols that mandate pre-screening for sexually transmitted infection prior to insertion of an intrauterine device for contraception can pose obstacles for women seeking this highly effective method of birth control. Some practices screen for presumed risk factors for sexually... | 2012-01-01 | |

 | Andrus, Jennifer | Critical discourse analysis and rhetoric and composition | Over the past two decades, critical discourse analysis has emerged as a major new multidisciplinary approach to the study of texts and contexts in the public sphere. Developed in Europe, CDA has lately become increasingly popular in North America, where it is proving especially congenial to new dire... | 2012-01-01 | |

 | Gale, Bruce K. | Cyclical magnetic field flow fractionation | In this study, a new magnetic field flow fractionation (FFF) system was designed and modeled by using finite element simulations. Other than current magnetic FFF systems, which use static magnetic fields, our system uses cyclical magnetic fields. Results of the simulations show that our cyclical mag... | 2012-01-01 | |

 | Thomas, Kirk R. | Cytochrome P450 2B diversity and dietary novelty in the herbivorous, desert woodrat (Neotoma lepida) | Detoxification enzymes play a key role in plant-herbivore interactions, contributing to the on-going evolution of ecosystem functional diversity. Mammalian detoxification systems have been well studied by the medical and pharmacological industries to understand human drug metabolism; however, little... | 2012-01-01 | |

 | Jalili, Thunder | Cytosolic, but not mitochondrial, oxidative stress likely contributes to cardiac hypertrophy resulting from cardiac specific GLUT4 deletion in mice | We hypothesized that oxidative stress may contribute to the development of hypertrophy observed in mice with cardiac specific ablation of the insulin sensitive glucose transporter gene (GLUT4, G4H-/-4 ). Measurements of oxidized glutathione (GSSG) in isolated mitochondria and whole heart homogenates... | 2012-01-01 | |

 | Berzins, Martin | DAG-based software frameworks for PDEs | The task-based approach to software and parallelism is well-known and has been proposed as a potential candidate, named the silver model, for exas-cale software. This approach is not yet widely used in the large-scale multi-core parallel computing of complex systems of partial differential equations... | 2012-01-01 | |

 | Berzins, Martin | Data and range-bounded polynomials in ENO methods | Essentially Non-Oscillatory (ENO) methods and Weighted Essentially Non- Oscillatory (WENO) methods are of fundamental importance in the numerical solution of hyperbolic equations. A key property of such equations is that the solution must remain positive or lie between bounds. A modification of the ... | 2012-01-01 | |
