    SSR and SCAR markers linked to the fertility-restoring gene for a D2-type cytoplasmic male-sterile line in wheat (2005)

    Notes: ‘Yi 4060’ is an elite restorer line of a non-photoperiod-sensitive D2-type cytoplasmic male-sterile (CMS) line of wheat. Random amplified polymorphic DNA (RAPD) and simple sequence repeat (SSR) markers were employed to map one major fertility-restoring gene (D2Rf1) in ‘Yi 4060′. The sterile and fertile DNA pools were established from individuals in BC6, based on bulked segregant analysis. One RAPD marker E09, linked to D2Rf1, was converted to a SCAR marker and designated as E09-SCAR865. The genetic distance between E09-SCAR865 and D2Rf1 is 9.5 cM. Two SSR markers, Xgwm11 and Xgwm18, were also linked to a D2Rf1 and co-segregated with E09-SCAR865. The three molecular markers are useful in marker-assisted breeding of the elite restorer lines for D2 -type CMS lines in wheat.

    Notes: Computation of three-dimensional (3-D) Rayleigh–Taylor instability in compressible fluids is performed on a MIMD computer. A second-order TVD scheme is applied with a fully parallelized algorithm to the 3-D Euler equations. The computational program is implemented for a 3-D study of bubble evolution in the Rayleigh–Taylor instability with varying bubble aspect ratio and for large-scale simulation of a 3-D random fluid interface. The numerical solution is compared with the experimental results by Taylor.

    Plasma formation and equilibrium in a high β tokamak (1987)
    [S.l.] : American Institute of Physics (AIP)

    Notes: The formation and equilibrium of a high β tokamak in the Columbia High Beta Tokamak (HBT) (Plasma Physics and Controlled Nuclear Fusion Research 1986, in press) is documented using magnetic probes as the principle diagnostic. The formation from a toriodal field stabilized Z pinch is simulated with 2-D resistive magnetohydrodynamic (MHD) equations. From the measurement of the magnetic field by high-impedence internal magnetic probes, the poloidal flux, toroidal current, and safety factor are calculated. In addition, the plasma position and cross-sectional shape are determined. The tokamak has a major radius of about 0.24 m, a minor radius of about 0.05 m, and a toroidal current density of about 106 A/m2. The high β tokamak plasma is observed to have an outward shift in major radius of both the magnetic center and the peak of the toroidal current density. The magnetic center moves inward in major radius after 20–30 μsec, presumably because the plasma maintains major radial equilibrium as its pressure decreases because of the radiation of impurity atoms.

    A numerical study of three-dimensional bubble merger in the Rayleigh–Taylor instability (1996)

    Notes: The Rayleigh–Taylor instability arises when a heavy fluid adjacent to a light fluid is accelerated in a direction against the density gradient. Under this unstable configuration, a perturbation mode of small amplitude grows into bubbles of the light fluid and spikes of the heavy fluid. Taylor discovered the steady state motion with constant velocity for a single bubble or periodic bubbles in the Rayleigh–Taylor instability. Read and Youngs studied the motion of a randomly perturbed fluid interface in the Rayleigh–Taylor instability. They reported constant acceleration for the overall bubble envelope. Bubble merger is believed to cause the transition from constant velocity to constant acceleration. In this paper, we present a numerical study of this important physical phenomenon. It analyzes the physical process of bubble merger and the relationship between the horizontal bubble expansion and the vertical interface acceleration. A dynamic bubble velocity, beyond Taylor's steady state value, is observed during the merger process. It is believed that this velocity is due to the superposition of the bubble velocity with a secondary subharmonic unstable mode. The numerical results are compared with experiments. © 1996 American Institute of Physics.

    A comparative numerical study of the Richtmyer-Meshkov instability with nonlinear analysis in two and three dimensions (1997)

    Notes: A shock driven inter-facial instability, known as the Richtmyer-Meshkov instability, is studied numerically in two and three dimensions and in the nonlinear regime. The numerical solution is tested for convergence under computational mesh refinement and is compared with the predictions of a recently developed nonlinear theory based on the Padé approximation and asymptotic matching. Good agreement has been found between numerical solutions and predictions of the nonlinear theory in both two and three dimensions and for both the reflected shock and the reflected rarefaction wave cases. The numerical study is extended to the re-shock experiment in which the fluid interface interacts initially with the incident shock. Later, as the transmitted shock bounces back from the wall, the fluid interface is re-shocked. © 1997 American Institute of Physics.

    A numerical study of bubble interactions in Rayleigh–Taylor instability for compressible fluids (1990)

    Notes: The late nonlinear and chaotic stage of Rayleigh–Taylor instability is characterized by the evolution of bubbles of the light fluid and spikes of the heavy fluid, each penetrating into the other phase. This paper is focused on the numerical study of bubble interactions and their effect on the statistical behavior and evolution of the bubble envelope. Compressible fluids described by the two-fluid Euler equations are considered and the front tracking method for numerical simulation of these equations is used. Two major phenomena are studied. One is the dynamics of the bubbles in a chaotic environment and the interaction among neighboring bubbles. Another one is the acceleration of the overall bubble envelope, which is a statistical consequence of the interactions of bubbles. The main result is a consistent analysis, at least in the approximately incompressible case of these two phenomena. The consistency encompasses the analysis of experiments, numerical simulation, simple theoretical models, and variation of parameters. Numerical simulation results that are in quantitative agreement with laboratory experiment for one-and-one-half (1 (1)/(2) ) generations of bubble merger are presented. To the authors' knowledge, computations of this accuracy have not previously been obtained.

    Validation of the Sharp–Wheeler bubble merger model from experimental and computational data (1988)
    [S.l.] : American Institute of Physics (AIP)

    Notes: A statistical model to describe the late time chaotic behavior of a Rayleigh–Taylor unstable interface was introduced by Sharp and Wheeler [Physica D 12, 3 (1984); (private communication)]. Here the focus is on effective computations using this model and the comparison of the model with experiment. The numerical solution of the model shows that the height of the mixing layer, in which the bubbles of the light fluid penetrate the heavy fluid, is in a constant acceleration. This result agrees with the experiments of Read [Physica D 12, 45 (1984)].

    Parallel molecular stacks of organic thin film with electrical bistability (2000)

    Notes: A thin film of 1,1-dicyano-2,2-(4-dimethylaminophenyl) ethylene (DDME) has been grown by a modified vacuum deposition. The films were characterized by Fourier transform infrared spectroscopy, transmission electron microscopy, and scanning tunneling microscopy (STM). Highly ordered parallel molecular stacks were repeatedly observed with STM under ambient conditions. The dc current–voltage (I–V) characteristics of device Au/DDME/Au were measured, and the film was found to possess good electrical bistability and electrochromic properties. Nanometer-scale recording was realized on the film by applying pulse voltage between the STM tip and substrate. The possible switching mechanism is discussed. © 2000 American Institute of Physics.
