Sokolsky, Pierre | Energy estimation of UHE cosmic rays using the atmospheric fluorescence technique | We use the CORSIKA air shower simulation program to review the method for assigning energies to ultra-high energy (UHE) cosmic rays viewed with the air fluorescence technique. This technique uses the atmosphere as a calorimeter, and we determine the corrections that must be made to the calorimetric ... | Fluorescence; Energy estimation; Ultra-high energy cosmic rays | 2000-08 |

Liu, Feng | Equilibrium shape of two-dimensional islands under stress | We show that the equilibrium shape anisotropy of two-dimensional islands in heteroepitaxial growth depends on island size, a consequence of the presence of strain. Even in homoepitaxy, in which the island shape has conventionally been equated with the ratio of step energies, a substrate surface str... | Two-dimensional islands; Equilibrium shape; Heteroepitaxial growth; Homoepitaxy | 2000-08 |

Christensen, Douglas A.; Furse, Cynthia M. | Problem and treatment of DC offsets in FDTD simulations | This paper discusses the causes of and some solutions to the commonly observed problem of dc field offsets in finite-difference time-domain (FDTD) simulations. DC electric and magnetic field offsets are shown to be valid calculated responses of the modeled systems, resulting from interaction betwee... | Finite-difference time-domain method; Direct current offsets; Waveforms | 2000-08 |
