Mathews, V. John | Equalization of excursion and current-dependent nonlinearities in loudspeakers | This paper presents a novel equalizer for nonlinear distortions in direct-radiator loudspeakers in a closed cabinet by constructing an exact inverse of an electro-mechanical model of the loudspeaker. This exact inverse compensates for distortions introduced by excursion and current-dependent nonline... | 2014-01-01 | |

Miller, Jan D. | Erratum to Evaluation of stucco binder for agglomeration in the heap leaching of copper ore | Figure 8 top legend is mentioned incorrectly. The legend "With ferric sulfate: column leaching of agglomerates (stucco) should be red in color and column leaching of agglomerates (no stucco) should be blue in color. The correct Fig. 8 is shown below. The authors would like to apologize for the incon... | 2011-01-01 | |

Mansour, Suzanne L. | Fgf10 is required for specification of non-sensory regions of the cochlear epithelium | The vertebrate inner ear is a morphologically complex sensory organ comprised of two compartments, the dorsal vestibular apparatus and the ventral cochlear duct, required for motion and sound detection, respectively. Fgf10, in addition to Fgf3, is necessary for the earliest stage of otic placode ind... | 2014-01-01 | |

Utz, Rebecca L. | Feeling lonely vs. being alone: loneliness and social support among recently bereaved persons | Objectives: Despite increases in social support following widowhood, loneliness is among the most frequently reported challenges of bereavement. This analysis explores the dynamic relationship between social support and loneliness among recently bereaved older adults. Methods: Using longitudinal dat... | 2014-01-01 | |

Zick, Cathleen D. | Family, frailty, and fatal futures? Own-health and family-health predictors of subjective life expectancy | Subjective life expectancy is a powerful predictor of a variety of health and economic behaviors. This research expands upon the life expectancy literature by examining the influence of familial health histories. Using a genetic/environmental model, we hypothesize that individuals' assessments of th... | 2014-01-01 | |

Simpson, Jamesina J. | FDTD modeling of a novel ELF radar for major oil deposits using a three-dimensional geodesic grid of the earth-ionosphere waveguide | This paper reports the first application of an optimized geodesic, three-dimensional (3-D) finite-difference time-domain (FDTD) grid to model impulsive, extremely low-frequency (ELF) electromagnetic wave propagation within the entire Earth-ionosphere cavity. This new model, which complements our pre... | 2006-01-01 | |

Garrett, Timothy J. | Fall speed measurement and high-resolution multi-angle photography of hydrometeors in free fall | We describe here a new instrument for imaging hydrometeors in free fall. The Multi-Angle Snowflake Camera (MASC) captures high-resolution photographs of hydrometeors from three angles while simultaneously measuring their fall speed. Based on the stereoscopic photographs captured over the two months ... | 2012-01-01 | |

Hawkes, Kristen | Family provisioning is not the only reason men hunt | Gurven and Hill (2009) ask, "Why do mean hunt?" As they say, "The observation that mean hunt and women gather supported the simplistic view of marriage as a cooperative enterprise. Greater sophistication suggests that males may often be motivated by mating and status rather than offspring investment... | 2010-01-01 | |

Simpson, Jamesina J. | FDTD calculations of the diffraction coefficient of vibrating wedges | The full-vector Maxwell's equations finite-difference time-domain (FDTD) method is employed to calculate diffraction coefficients of vibrating conducting and dielectric wedges. Two-dimensional FDTD models of right-angle wedges are constructed to include total-field scattered-field incident plane-wav... | 2011-01-01 | |

Dailey, Andrew T. | Guideline update for the performance of fusion procedures for degenerative disease of the lumbar spine. Part 3: Assessment of economic outcome | A comprehensive economic analysis generally involves the calculation of indirect and direct health costs from a societal perspective as opposed to simply reporting costs from a hospital or payer perspective. Hospital charges for a surgical procedure must be converted to cost data when performing a c... | 2014-01-01 | |

Dailey, Andrew T. | Guideline update for the performance of fusion procedures for degenerative disease of the lumbar spine. Part 4: Radiographic assessment of fusion status | The ability to identify a successful arthrodesis is an essential element in the management of patients undergoing lumbar fusion procedures. The hypothetical gold standard of intraoperative exploration to identify, under direct observation, a solid arthrodesis is an impractical alternative. Therefore... | 2014-01-01 | |

Dailey, Andrew T. | Guideline update for the performance of fusion procedures for degenerative disease of the lumbar spine. Part 9: Lumbar fusion for stenosis with spondylolisthesis | Patients presenting with stenosis associated with a spondylolisthesis will often describe signs and symptoms consistent with neurogenic claudication, radiculopathy, and/or low-back pain. The primary objective of surgery, when deemed appropriate, is to decompress the neural elements. As a result of t... | 2014-01-01 | |

Dailey, Andrew T. | Guideline update for the performance of fusion procedures for degenerative disease of the lumbar spine. Part 7: Lumbar fusion for intractable low-back pain without stenosis or spondylolisthesis | Establishing an appropriate treatment strategy for patients presenting with low-back pain, in the absence of stenosis or spondylolisthesis, remains a controversial subject. Inherent to this situation is often an inability to adequately identify the source of low-back pain to justify various treatmen... | 2014-01-01 | |

Dailey, Andrew T. | Guideline update for the performance of fusion procedures for degenerative disease of the lumbar spine. Part 8: Lumbar fusion for disc herniation and radiculopathy | Patients suffering from a lumbar herniated disc will typically present with signs and symptoms consistent with radiculopathy. They may also have low-back pain, however, and the source of this pain is less certain, as it may be from the degenerative process that led to the herniation. The surgical al... | 2014-01-01 | |

Dailey, Andrew T. | Guideline update for the performance of fusion procedures for degenerative disease of the lumbar spine. Part 6: Discography for patient selection | Identifying the etiology of pain for patients suffering from chronic low-back pain remains problematic. Noninvasive imaging modalities, used in isolation, have not consistently provided sufficient evidence to support performance of a lumbar fusion. Provocative testing has been used as an adjunct in ... | 2014-01-01 | |

New York: Oxford University Press, 2012, ix+302 pp, ISBN: 978-0-19-977528-6, $65 HB. | Thomas Pradeu's The Limits of the Self provides a precise account of biological identity developed from the central concepts of immunology. Yet the central concepts most relevant to this task (self and nonself ) are themselves deemed inadequate, suffering from ambiguity and imprecision. Pradeu seeks... | 2014-01-01 | |
