Varner, Michael W. | Association of obesity with pulmonary and nonpulmonary complications of pregnancy in asthmatic women. | OBJECTIVE: To evaluate whether maternal obesity is associated with pulmonary and nonpulmonary pregnancy complications in asthmatic women. METHODS: This is a secondary analysis of the prospective cohort Asthma During Pregnancy Study. Asthma patients were classified as having either mild or moderate t... | Asthma; Body Mass Index; Pregnancy Outcome; Lung Diseases | 2006-07 |

Wu, Yong-Shi | Braid group, gauge invariance, and topological order | Topological order in two-dimensional systems is studied by combining the braid group formalism with a gauge invariance analysis. We show that flux insertions (or large gauge transformations) pertinent to the toroidal topology induce automorphisms of the braid group, giving rise to a unified algebrai... | Braid group; Topological order; Zero temperature; Two-dimensional systems | 2006-07 |

Varner, Michael W. | Decision-to-incision times and maternal and infant outcomes. | OBJECTIVE: To measure decision-to-incision intervals and related maternal and neonatal outcomes in a cohort of women undergoing emergency cesarean deliveries at multiple university-based hospitals comprising the National Institute of Child Health and Human Development Maternal-Fetal Medicine Units N... | Cesarean Section; Fetal Distress; Outcome Assessment; Fetal Distress | 2006-07 |

Couldwell, William T.; Apfelbaum, Ronald I. | Decompression of cavernous sinus meningioma for preservation and improvement of cranial nerve function | Meningiomas are the most common tumors affecting the cavernous sinus (CS). Despite advances in microsurgery and radiosurgery, treatment of CS meningiomas remains difficult and controversial. As in cases of other meningiomas, the goal of treatment for CS meningioma is long-term growth control and pre... | 2006-07 | |

Khan, Faisal Habib | Deriving new topologies of DC-DC converters featuring basic switching cells | This paper will introduce the two basic switching cells, P-cell and N-cell, and their applications in different power electronic circuits. These basic cells have one switching element and one diode. The P-cell is the mirror circuit of the N-cell and vice-versa, and this paper suggests that any powe... | DC-DC converters; P-cell; N-cell; Switching cells; Cúk converters | 2006-07 |

Harrison, Reid R. | Design and implementation of multipattern generators in analog VLSI | In recent years, computational biologists have shown through simulation that small neural networks with fixed connectivity are capable of producing multiple output rhythms in response to transient inputs. It is believed that such networks may play a key role in certain biological behaviors such as d... | 2006-07 | |

Zimmer, Zachary | Disability and active life expectancy among older Cambodians | Older adults in Cambodia are survivors of harsh living conditions, including poverty and periods of extreme violence. Although these experiences may affect health outcomes, little data has existed to monitor Cambodia's older population. The current paper uses data from the 2004 Study of the Elder... | Active Life Expectancy; Ageing; Cambodia; Disability; Functional Status; Southeast Asia | 2006-07 |

Wu, Yong-Shi | General theorem relating the bulk topological number to edge states in two-dimensional insulators | We prove a general theorem on the relation between the bulk topological quantum number and the edge states in two-dimensional insulators. It is shown that whenever there is a topological order in bulk, characterized by a nonvanishing Chern number, even if it is defined for a nonconserved quantity s... | Edge states; Bulk topology; Chern number | 2006-07 |

Gondolo, Paolo | Neutralino with the right cold dark matter abundance in (almost) any supersymmetric model | We consider nonstandard cosmological models in which the late decay of a scalar field Ø reheats the Universe to a low reheating temperature, between 5 MeV and the standard freeze-out temperature of neutralinos of mass mx. We point out that in these models all neutralinos with standard density Ώstd... | Neutralinos; Reheating temperature | 2006-07 |

Liu, Feng | Pressure-induced transition in magnetoresistance of single-walled carbon nanotubes | We applied hydrostatic pressure (up to 10 GPa) to single-walled carbon nanotube bundles at low temperature (down to 2 K) to measure their magnetoresistance (MR) in a field up to 12 T. We found a pressure-induced transition in MR from positive to negative in the high-field regime. The onset of the tr... | Single-walled carbon nanotubes; Pressure-induced | 2006-07 |

Varner, Michael W. | Risk of uterine rupture with a trial of labor in women with multiple and single prior cesarean delivery. | OBJECTIVE: To determine whether the risk for uterine rupture is increased in women attempting vaginal birth after multiple cesarean deliveries. METHODS: We conducted a prospective multicenter observational study of women with prior cesarean delivery undergoing trial of labor and elective repeat oper... | Cesarean Section, Repeat; Uterine Rupture; Vaginal Birth after Cesarean; Obstetric Labor Complications/surgery | 2006-07 |

Varner, Michael W. | Trial of labor or repeat cesarean delivery in women with morbid obesity and previous cesarean delivery. | OBJECTIVE: Assess effects of body mass index (BMI) on trial of labor after previous cesarean delivery and determine whether morbidly obese women have greater maternal and perinatal morbidity with trial of labor compared with elective repeat cesarean delivery. METHODS: Secondary analysis from a prosp... | Pregnancy Outcome; Obesity; Repeat Cesarean Section; Body Mass Index | 2006-07 |
