Family of equations of state based on lattice QCD: Impact on flow in ultrarelativistic heavy-ion collisions
Bluhm, M.; Kämpfer, B.; Schulze, R.; Seipt, D.; Heinz, U. ( 2007-09-17 )We construct a family of equations of state within a quasiparticle model by relating pressure, energy density, baryon density, and susceptibilities adjusted to first-principles lattice QCD calculations. The relation between ... -
Fast diffusion mechanism of silicon tri-interstitial defects
Du, Yaojun A.; Barr, Stephen A.; Hazzard, Kaden R. A.; Lenosky, Thomas J.; Hennig, Richard G.; Wilkins, John W. ( 2005-12-15 )Molecular dynamics combined with the nudged elastic band method reveals the microscopic self-diffusion process of compact silicon tri-interstitials. Tight-binding molecular dynamics paired with ab initio density functional ... -
Father-Son Incest: Underreported Psychiatric Problem?
Dixon, Katharine N.; Arnold, L. Eugene; Calestro, Kenneth ( 1978 )Six families are described in which 10 sons were involved incestuously with a natural father (N=4) or step-father (N=2). Father-son incest as a part of the spectrum of child abuse appears to be a more frequent clinical ... -
Fecundity selection in a sunflower crop–wild study: can ecological data predict crop allele changes?
Cummings, Charity L.; Alexander, Helen M.; Snow, Allison A.; Rieseberg, Loren H.; Kim, Min Ju; Culley, Theresa M. ( 2002-12 )Genes that spread from transgenic crops to populations of weedy relatives can be a cause of concern if fitness-related, transgenic traits persist and enhance weed invasiveness. Studies of the prevalence of crop-specific ... -
Femtolens Imaging of a Quasar Central Engine Using a Dwarf Star Telescope
Gould, Andrew; Gaudi, B. Scott ( 1997-09-10 )We show that it is possible to image the structure of a distant quasar on scales of <~ AU by constructing a telescope that uses a nearby dwarf star as its "primary lens" together with a satellite-borne "secondary." The ... -
Fermions in 2D Optical Lattices: Temperature and Entropy Scales for Observing Antiferromagnetism and Superfluidity
Paiva, Thereza; Scalettar, Richard; Randeria, Mohit; Trivedi, Nandini ( 2010-02-11 )One of the major challenges in realizing antiferromagnetic and superfluid phases in optical lattices is the ability to cool fermions. We determine constraints on the entropy for observing these phases in two-dimensional ... -
Field evaluation of application variables and plant density for bell pepper pest management
Derksen, R. C.; Vitanza, S.; Welty, C.; Miller, S.; Bennett, M.; Zhu, H. ( 2007-11 )Bell peppers are a valuable vegetable crop in the U.S. Management of pepper insects and diseases relies on chemical control options. Because there are relatively few chemical options available for pepper pest management, ... -
Figures of merit for present and future dark energy probes
Mortonson, Michael J.; Huterer, Dragan; Hu, Wayne ( 2010-09-14 )We compare current and forecasted constraints on dynamical dark energy models from Type Ia supernovae and the cosmic microwave background using figures of merit based on the volume of the allowed dark energy parameter ... -
Filifactor alocis - involvement in periodontal biofilms
Schlafer, Sebastian; Riep, Birgit; Griffen, Ann; Petrich, Annett; Hubner, Julia; Berning, Moritz; Friedmann, Anton; Gobel, Ulf; Moter, Annette ( 2010-03-01 )Background. Bacteria in periodontal pockets develop complex sessile communities that attach to the tooth surface. These highly dynamic microfloral environments challenge both clinicians and researchers ... -
Fine structure radiative transitions in C II and C III using the Breit-Pauli R-matrix method
Nahar, Sultana Nurun ( 2002 )Extensive sets of radiative transitions in C II and in C III are obtained using the relativistic Breit-Pauli R-matrix (BPRM) method. In comparison with other accurate methods that can be applied to relatively few transitions, ... -
The First Mid-Infrared Spectra of Cool White Dwarfs
Kilic, Mukremin; Kowalski, Piotr M.; Mullally, Fergal; Reach, William T.; von Hippel, Ted ( 2008-05-10 )We present the first mid-infrared spectra of two cool white dwarfs obtained with the Spitzer Space Telescope. We also present 3.5–8 μ m photometry for 19 cool white dwarfs with 5000 K ≤ T_eff ≤ 9000 K. We perform a detailed ... -
Fitness of hybrids between weedy and cultivated radish: implications for weed evolution
Snow, Allison A.; Uthus, Kristen L.; Culley, Theresa M. ( 2001-06 )Weed species are known to evolve rapidly with their associated crops. A better understanding of the mechanisms and rates of weed evolution could aid in limiting or at least anticipating this process. Spontaneous hybridization ... -
Fitted Hanbury-Brown-Twiss radii versus space-time variances in flow-dominated models
Frodermann, Evan; Heinz, Ulrich; Lisa, Michael Annan ( 2006-04-24 )The inability of otherwise successful dynamical models to reproduce the Hanbury-Brown-Twiss (HBT) radii extracted from two-particle correlations measured at the Relativistic Heavy Ion Collider (RHIC) is known as the RHIC ... -
Force-matched embedded-atom method potential for niobium
Fellinger, Michael R.; Park, Hyoungki; Wilkins, John W. ( 2010-04-19 )Large-scale simulations of plastic deformation and phase transformations in alloys require reliable classical interatomic potentials. We construct an embedded-atom method potential for niobium as the first step in alloy ... -
