 | Mishchenko, Eugene | Small-angle impurity scattering and the spin Hall conductivity in two-dimensional semiconductor systems | An arbitrarily small concentration of impurities can affect the spin Hall conductivity in a two-dimensional semiconductor system. We develop a Boltzmann-like equation that can be used for impurity scattering with an arbitrary angular dependence, and for an arbitrary angular dependence of the spin-o... | Spin Hall conductivity; Impurity scattering; Spin-orbit coupling | 2006-02 |

 | Landesman, Margaret M. | SNARB - coming soon to a library near you | Author's note: I wanted to write something provocative and a bit funny, thinking about the shrinking differences between libraries and bookstores; and about what happens for good and ill as we are able to search across greater and greater aggregations from disparate parts of our lives. This is how i... | Libraries; Bookstores | 2006-04 |

 | Gondolo, Paolo | Stellar orbit constraints on neutralino annihilation at the galactic center | Dark matter annihilation has been proposed to explain the TeV gamma rays observed from the Galactic Center. We study constraints on this hypothesis coming from the mass profile around the Galactic Center measured by observing stellar dynamics. We show that for several proposed WIMP candidates, the... | Neutralinos; Annihilation | 2006-09 |

 | Liu, Feng | Surface mobility difference between Si and Ge and its effect on growth of SiGe alloy films and islands | Based on first-principles calculations of surface diffusion barriers, we show that on a compressive Ge(001) surface the diffusivity of Ge is 102-103 times higher than that of Si in the temperature range of 300 to 900 K, while on a tensile surface, the two diffusivities are comparable. Consequently, ... | Surface mobility; SiGe film; Strained thin films; Surface diffusion barriers | 2006-01 |

 | Wu, Yong-Shi | Topological quantization of the spin Hall effect in two-dimensional paramagnetic semiconductors | We propose models of two-dimensional paramagnetic semiconductors where the intrinsic spin Hall effect is exactly quantized in integer units of a topological charge. The model describes a topological insulator in the bulk and a "holographic metal" at the edge, where the number of extended edge stat... | Topological insulator; Holographic metal; Edge states | 2006-08 |

 | Boehme, Christoph | Transport and recombination through weakly coupled localized spin pairs in semiconductors during coherent spin excitation | Semianalytical predictions for the transients of spin-dependent transport and recombination rates through localized states in semiconductors during coherent electron-spin excitation are made for the case of weakly spin-coupled charge-carrier ensembles. The results show that the on-resonant Rabi freq... | Larmor frequency; Larmor separations | 2006-12 |

 | 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.

 | Mishchenko, Eugene; Raikh, Mikhail E. | Tunneling between two-dimensional electron layers with correlated disorder: anomalous sensitivity to spin-orbit coupling | Tunneling between two-dimensional electron layers with mutually correlated disorder potentials is studied theoretically. Due to this correlation, the diffusive eigenstates in different layers are almost orthogonal to each other. As a result, a peak in the tunnel I-V characteristics shifts towards s... | Spin-orbit coupling | 2006-11 |

 | Boehme, Christoph | Ultra-sensitive electrical detection of spin Rabi oscillation at paramagnetic defects | A short review of the pulsed electrically detected magnetic resonance (pEDMR) experiment is presented. PEDMR allows the highly sensitive observation of coherent electron spin motion of charge carriers and defects in semiconductors by means of transient current measurements. The theoretical foundatio... | Rabi oscillations; Electron spin resonance; Paramagnetic defects | 2006-04 |

 | Sekercioglu, Cagan | A birders quide to Turkey | As I write, it is early December and the woods outside my window lay dusted with snow like a holiday card by Currier and Ives. A minute ago, I looked up and caught a glimpse of an adult Cooper's Hawk dashing swiftly through the trees. It swooped up, landed on a branch, then briefly shook its tail an... | | 2006-01-01 |

 | Gopalakrishnan, Ganesh | A general compositional approach to verifying hierarchical cache coherence protocols | Modern chip multiprocessor (CMP) cache coherence protocols are extremely complex and error prone to design. Modern symbolic methods are unable to provide much leverage for this class of examples. In [1], we presented a method to verify hierarchical and inclusive versions of these protocols using ... | Hierarchical cache coherence protocols; Verification | 2006-11-26 |

 | Simpson, Jamesina J. | A novel ELF radar for major oil deposits | This letter proposes a novel extremely low frequency (ELF) radar for major oil deposits. Using our recently developed whole-Earth electromagnetic wave propagation model based upon the finite-difference time-domain method, we have determined that detection of the radial (vertical) component of the sc... | | 2006-01-01 |

 | Zimmer, Zachary | Accounting for urban versus rural discrepancies in mortality and functional health among older adults in China | Broad differences exist in social and economic life between residents living in urban versus rural areas of China. To study the health implications of these differences, the current study employs data from a longitudinal study of older adults in the Beijing municipality, a region of China that has w... | Chinese; Elderly; Health care; Quality of life; Population | 2006-09-05 |

 | Martin, Jim | Aerodynamic drag area of cyclists determined with field-based measures | Aerodynamic drag is an important factor in the performance of competitive track and road cyclists. Recently we used wind-tunnel testing to validate a practical measure of aerodynamic drag derived from a field test. We present here instructions for performing the field test on a straight flat road or... | | 2006-01-01 |

 | Hall, Thad | Are Americans confident their ballots are counted? | Expanding the large literature which investigates the characteristics of citizen and voter trust in government we analyze the heretofore neglected topic of voter trust in the electoral process. In this paper, we present results from three national surveys in which we asked voters the confidence they... | Election reform; public management; principal-agent theory | 2006-07-20 |

 | Petti, Cathy A.; Polage, Christopher R. | Assessment of the utility of viral culture of cerebrospinal fluid | Nucleic acid amplification testing is the preferred method to detect enteroviruses and Herpesviridae in cerebrospinal fluid, but clinicians still request viral culture. Review of 22,394 viral cultures of cerebrospinal fluid samples found that <0.1% recovered nonenterovirus, non-Herpesviridae species... | Enterovirus Infections; Herpesviridae Infections; Virus Cultivation | 2006-12-15 |

 | Regehr, John | Atomicity and visibility in tiny embedded systems | Visibility is a property of a programming language's memory model that determines when values stored by one concurrent computation become visible to other computations. Our work exploits the insight that in nesC, a C-like language with explicit atomicity, the traditional way of ensuring timely visib... | | 2006-01-01 |

 | Wu, Yong-Shi | BPS R-balls in N = 4 SYM on R × S3, quantum Hall analogy and AdS/CFT holography | In this paper, we propose a new approach to study the BPS dynamics in N = 4 supersymmetric U(N) Yang-Mills theory on R × S3, in order to better understand the emergence of gravity in the gauge theory. Our approach is based on supersymmetric, space-filling Q-balls with R-charge, which we call R-ball... | | 2006-06-01 |
