Riloff, Ellen M. | Bootstrapping method for learning semantic lexicons using extraction pattern contexts | This paper describes a bootstrapping algorithm called Basilisk that learns high-quality semantic lexicons for multiple categories. Basilisk begins with an unannotated corpus and seed words for each semantic category, which are then bootstrapped to learn new words for each category. Basilisk hypothe... | Basilisk; Bootstrapping method; Semantic lexicons | 2002 |

Chapman, David S. | Borehole temperatures and climate change: ground temperature change in south India over the past two centuries | Variations in surface g round temperature (SGT) at the Earth's surface diffuse downward in a predictable way causing systematic perturbations to the subsurface temperature field. The pioneering study of Lachenbruch and Marsh all [1986] in Alaska demonstrated that present-day borehole temperature-dep... | | 2012-01-01 |

McDaniel, Susan | Born at the right time?: gendered generations and webs of entitlement and responsibility | Analyses of social change and challenge in sociologies for women often start with some attention to generation. Yet, generation per se has been an underconceptualized sociological construct as a structural dimension of stratification, particularly gender stratification, or as a lens through which... | Generation; Gender; Women | 2001 |

Wu, Yong-Shi | Bosonization of one-dimensional exclusons and characterization of Luttinger liquids | We achieve a bosonization of one-dimensional ideal gas of particles obeying exclusion statistics A (so called A exclusons) at low temperatures, resulting in a new variant of c = 1 conformal field theory with compactified radius R = √1/λ. These ideal excluson gases exactly reproduce the low-7 crit... | Bosonization; Exclusons; Ideal gas; Luttinger liquids | 1995-07 |

Mattis, Daniel C. | Bound exciton and hole: an exactly solvable three-body model in any number of dimensions | A three-body problem, concerning two holes in a nondegenerate valence band and a single electron in a conduction band, with strong short-range interactions, is solved exactly in any number of dimensions. The binding depends nontrivially on the ratio of the valence to conduction bandwidths (i.e., on ... | Three-body problem; Trion; Bond energies | 1982-09 |

Hansen, Charles D. | Boundary aware reconstruction of scalar fields | In visualization, the combined role of data reconstruction and its classification plays a crucial role. In this paper we propose a novel approach that improves classification of different materials and their boundaries by combining information from the classifiers at the reconstruction stage. Our ap... | | 2014-01-01 |

Tasdizen, Tolga | Boundary estimation from intensity/color images with algebraic curve models | A new concept and algorithm are presented for noniterative robust estimation of piecewise smooth curves of maximal edge strength in small image windows - typically 8 x 8 to 32 x 32. This boundary-estimation algorithm has the nice properties that it uses all the data in the window and thus can find l... | | 2000 |

Gopalakrishnan, Ganesh | Bounded transaction model checking | Industrial cache coherence protocol models often have too many reachable states, preventing full reachability analysis even for small model instances (number of processors, addresses, etc.). Several partial search debugging methods are, therefore, employed, including lossy state compression using... | Model checking; Reachability analysis | 2006-02-27 |

Golden, Kenneth M. | Bounds on the complex permittivity of matrix-particle composites | The complex effective dielectric constant E* of matrix-particle composites is considered. Such composites consist of separated inclusions of material of type one embedded in a matrix of material of type two. The analytic continuation method is used to derive a series of bounds which incorporate a n... | Random; Parameters; Continuation | 1995 |

Golden, Kenneth M. | Bounds on the complex permittivity of sea ice | An analytic method for obtaining bounds on effective properties of composites is applied to the complex permittivity e* of sea ice. The sea ice is assumed to be a two-component random medium consisting of pure ice of permittivity e1, and brine of permittivity e2. The method exploits the properties ... | Brine; Properties; Geometry | 1995 |

Kraus, Peter L. | Boys from the Brooklyn Museum venture to Zion | The Brooklyn Museum is the second largest museum in New York City, and one of the largest in the United States. Although now known primarily as an art museum, prior to the Second World War, the Museum pursued an aggressive acquisition policy in the field of Natural History and Archeology. Various me... | Naturalist; Engelhard, George P.; Entomology | 2008 |

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 |

Lupton, John Mark | Bragg scattering from periodically microstructured light emitting diodes | We present a simple method of generating a periodic wavelength scale structure in the optically active layer of a light emitting diode. This is achieved by solution deposition of a light emitting polymer on top of a corrugated substrate. The periodic structure allows waveguide modes normally trapped... | Bragg scattering; Periodic wavelength scale structure | 2000 |

Wu, Yong-Shi | Braid group and anyons on a cylinder | In this paper we present a careful reexamination of anyons on a cylinder (or annulus), starting from the braid-group analysis. Proper attention is paid to the topological features arising from the existence of noncontractible loops. The rule for putting anyons on a square lattice has to be modified ... | Braid group; Annulus | 1991-02 |

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 |

Mishchenko, Eugene | Breached superfluidity via p-wave coupling | Anisotropic pairing between fermion species with different Fermi momenta opens two-dimensional areas of gapless excitations, thus producing a spatially homogeneous state with coexisting superfluid and normal fluids. This breached pairing state is stable and robust for arbitrarily small mismatch and ... | Spin-orbit coupling; Gapless excitations; Cooper instability | 2005-03 |
