Golden, Kenneth M. | Inverse electromagnetic scattering models for sea ice | Inverse scattering algorithms for reconstructing the physical properties of sea ice from scattered electromagnetic field data are presented. The development of these algorithms has advanced the theory of remote sensing, particularly in the microwave region, and has the potential to form the basis f... | Polar ice; Electromagnetic scattering; Electromagnetic scattering inverse problems; Multilayer random media; Dielectric materials; Nonhomogeneous media; Remote sensing | 1998 |

Gondolo, Paolo | Wanted! Nuclear data for dark matter astrophysics | Astronomical observations from small galaxies to the largest scales in the universe can be consistently explained by the simple idea of dark matter. The nature of dark matter is however still unknown. Empirically it cannot be any of the known particles, and many theories postulate it as a new elemen... | | 2014-01-01 |

Bohs, Lynn A. | Four-gene study of evolutionary relationships in Solanum section Acanthophora | The "spiny solanums," Solanum subgenus Leptostemonum (Solanaceae), comprise a large lineage with over 350 species and include the cultivated eggplant, Solanum melongena.

Vardeny, Zeev Valentine | Recombination kinetics in ?-Si:H | Mort et al.1 reinterpreted our data on the relaxation of photoinduced absorption (PA) in a-Si:H. 2 We want to show that the proposed interpretation contradicts one basic feature of the data while our original interpretation is in good agreement with experiment. | Hydrogenated amorphous silicon; a-Si:H; Recombination kinetics; Photoinduced absorption; Decay; Relaxation | 1981 |

Kieda, David B. | High statistics search for ultrahigh energy gamma-ray emission from Cygnus X-3 and Hercules X-1 | We have carried out a high statistics (2 X 10 9 events) search for ultrahigh energy g-ray emission from the x-ray binary sources Cygnus X-3 and Hercules X-1. Using data taken with the CASA-MIA detector over a five year period (1990-1995), we find no evidence for steady emission from either source.

Clayton, Dale H.; Rogers, Alan R. | Genetic analysis of lice supports direct contact between modern and archaic humans | Parasites can be used as unique markers to investigate host evolutionary history, independent of host data. Here we show that modern human head lice, Pediculus humanus, are composed of two ancient lineages, whose origin predates modern Homo sapiens by an order of magnitude (ca. 1.18 million years). | Pediculus humanus; Head lice; Molecular phylogeny; Phthirus | 2004 |

Sokolsky, Pierre | High Resolution Fly's Eye - status and preliminary results on cosmic ray composition above 10^18 eV | We describe the current status of the High Resolution Fly's Eye detector. Event reconstruction and associated systematics for stereo reconstruction are discussed and recent preliminary results on the study of the composition of ultra-high energy cosmic rays by the Xmax method are presented.

Sokolsky, Pierre | Total proton-proton cross section at s1/2=30 TeV | We have measured the proton-air inelastic cross section at s 1/2 = 30 TeV by observing the distribution of extensive-air-shower maxima as a function of atmospheric depth. This distribution has an exponential tail whose slope is λ = 72 ±9 g c m - 2 which implies that σ inel p-air = 530 ± 66 mb. U... | | 1984-04 |

Miller, Joel Steven; Epstein, Arthur J. | Viscous behavior in a quasi-1D fractal cluster glass | The spin glass transition of a quasi-1D organic-based magnet ([MnTPP][TCNE]) is explored using both ac and dc measurements. A scaling analysis of the ac susceptibility shows a spin glass transition near 4 K, with a viscous decay of the thermoremanent magnetization recorded above 4 K.We propose an ex... | Transition; Magnet; Magnetization | 2002 |
