Dailey, Andrew T. | Risk factors for respiratory failure following operative stabilization of thoracic and lumbar spine fractures | Background: Respiratory failure is a serious complication that can adversely affect the hospital course and survival of multiply injured patients. Some studies have suggested that delayed surgical stabilization of spine fractures may increase the incidence of respiratory complications. However, the... | Respiratory failure; Operative stabilization; Thoracic spine; Lumbar spine | 2006 |

Mallon, Ronald | Role of psychology in the study of culture | Although we are enthusiastic about a Darwinian approach to culture, we argue that the overview presented in the target article does not sufficiently emphasize the crucial explanatory role that psychology plays in the study of culture. We use a number of examples to illustrate the variety of ways by... | 2006 | |

Petti, Cathy A. | Role of the laboratory in diagnosis of influenza during seasonal epidemics and potential pandemics | Laboratory diagnosis of influenza is critical to its treatment and surveillance. With the emergence of novel and highly pathogenic avian influenza viruses, the role of the laboratory has been further extended to include isolation and subtyping of the virus to monitor its appearance and facilitate ap... | Antibodies, Viral; Antigens, Viral; RNA, Viral | 2006 |

Li, Minqi | Secular trends, long waves, and the cost of the state: evidence from the long-term movement of the profit rate in the U.S. economy | Theorists in the tradition of either Classical Marxism or Keynesianism understand that as capitalism provides an historical space for the development of material forces of production, its economic and social contradictions tend to develop, requiring progressively more complex institutional structure... | Marxism; Social structures of accumulation; Neoliberalism | 2006 |

Furse, Cynthia M. | Selection criteria of test signals for correlation-based wire fault analysis (preprint) | This paper compares reflectometry signals for location of intermittent faults on live electrical cables. STDR, SSTDR, linear chirp, quadratic chirp, concave-up chirp, convex-down chirp and all frequency randomized phase noise signals were tested. The SSTDR was observed to be the most effective sig... | 2006 | |

Kestle, John R. W. | Shunt insertion in the summer: is it safe? | Object. The potential for increased complications related to the arrival of new residents in July each year has not previously been demonstrated in the neurosurgical literature. The authors investigated this phenomenon in children undergoing cerebrospinal fluid shunt surgery. Methods.

Couldwell, William T. | Simple closure following transsphenoidal surgery | The most common nonendocrine complication after transsphenoidal surgery is cerebrospinal fluid (CSF) leak. Many neurosurgeons have advocated the routine reconstruction of the floor of the sella turcica using autologous fat, muscle, fascia, and either cartilage or bone after transsphenoidal surgery t... | 2006 | |

Williams, Clayton C. | Single electron tunneling force spectroscopy of an individual electronic state in a non-conducting surface | A tunneling spectroscopy technique to measure the energy level of an electronic state in a completely nonconducting surface is demonstrated. Spectroscopy is performed by electrostatic force detection of single-electron tunneling between a scanning probe and the state as a function of an applied vo... | Tunneling; Spectroscopy; Single electron; Scanning tunneling microscope | 2006 |

Sperry, John S. | Size and function in conifer tracheids and angiosperm vessels | The wide size range of conifer tracheids and angiosperm vessels has important consequences for function. In both conduit types, bigger is better for conducting efficiency. The gain in efficiency with size is maximized by the control of conduit shape, which balances end-wall and lumen resistances. | Ecological wood anatomy; vascular structure and function; water transport | 2006 |

Chuaqui, Miguel Basim | Sonora Run | Sonora Run is a 7 minute work for orchestra dedicated to the memory of the Chilean writer Roberto Bolaño. Although his novels take the reader all over the world, the Mexican state of Sonora and the Sonoran desert play a central role in several of his works, including his acclaimed major works, The... | Roberto Bolaño; Sonora Mexico | 2006 |

Couldwell, William T.; Harnsberger, H. Ric | Spontaneous regression of a cystic cavum septum pellucidum | A persistent cavum septum pellucidum (CSP) is present in ~0.73% of adults, although its incidence ranges from 0.14 to 18.9% depending on the detection method. Cystic CSP is even rarer. A cyst causing mass within the CSP can obstruct the intraventricular foramen, leading to blockage of CSF flow and p... | Cavum septum pellucidum; Cyst; Spontaneous regression; Decompression | 2006 |

Kestle, John R. W. | Sporadic osteochondroma of the cervical spine | Osteochondroma is the most common benign tumor of bone, but axial skeleton involvement is uncommon and usually indicates a hereditary cause such as osteochondromatosis (hereditary multiple exostosis). 1 Approximately 7% of hereditary osteochondromas occur along the vertebral column, which is double... | 2006 | |

Lupton, John Mark | Stimulated emission depletion of triplet excitons in a phosphorescent organic laser | Triplet formation is investigated in an optically pumped polymer laser by detecting the phosphorescence emission after excitation. A clear correlation is observed between the onset of lasing and a saturation of phosphorescence intensity due to stimulated emission depletion of the singlet state and t... | Triplet excitons; Triplet formation; Emission depletion; Phosphorescent organic laser; Optically pumped polymer laser | 2006 |

Mathews, V. John | Stochastic mean-square performance analysis of an adaptive Hammerstein filter | Abstract-This paper presents an almost sure mean-square performance analysis of an adaptive Hammerstein filter for the case when the measurement noise in the desired response signal is a martingale difference sequence. The system model consists of a series connection of a memoryless nonlinearity fol... | 2006 | |

Adler, Frederick R. | Stochasticity, complex spatial structure, and the feasibility of the shifting balance theory | Sewall Wright's shifting balance theory of evolution posits a mechanism by which a structured population may escape local fitness optima and find a global optimum. We examine a one-locus, two-allele model of underdominance in populations with differing spatial arrangements of demes, both analyticall... | Fitness landscape; Sewall Wright; Underdominance | 2006 |

Plutynski, Anya | Strategies of model building in population genetics | In 1966, Richard Levins argued that there are different strategies in model building in population biology. In this paper, I reply to Orzack and Sober's (1993) critiques of Levins and argue that his view on modeling strategies apply also in the context of evolutionary genetics. In particular, I arg... | 2006 | |

Mathews, V. John | Subband particle filtering for speech enhancement | ABSTRACT Particle filters have recently been applied to speech enhancement when the input speech signal is modeled as a time-varying autoregressive process with stochastically evolving parameters. This type of modeling results in a nonlinear and conditionally Gaussian statespace system that is not ... | 2006 | |

Couldwell, William T. | Submandibular-infratemporal interpositional carotid artery bypass for cranial base tumors and giant aneurysms | Cerebral revascularization is an important strategy in the surgical management of some complex cranial base tumors and unclippable aneurysms. A highflow bypass may be necessary in planned carotid occlusion or sacrifice.

Beckerle, Mary C.; Hoffman, Laura M. | Supervillin modulation of focal adhesions involving TRIP6/ZRP-1 | Cell-substrate contacts, called focal adhesions (FAs), are dynamic in rapidly moving cells. We show that supervillin (SV)-a peripheral membrane protein that binds myosin II and F-actin in such cells-negatively regulates stress fibers, FAs, and cell-substrate adhesion. The major FA regulatory sequenc... | Supervillin; Focal adhesions; Zyxin; LIM domains; TRIP6 | 2006 |

Couldwell, William T.; MacDonald, Joel D. | Surgical strategies for recurrent craniofacial meningiomas | Recurrent cranial base meningiomas are among the most difficult tumors to treat surgically. Although they are histologically benign, these tumors often invade through the cranial base into the infratemporal and pterygopalatine fossae. We reviewed our experience with these tumors to describe the nat... | Craniofacial meningiomas; Recurrence; Cranial base tumor; Neoplasm | 2006 |
