A model of flow and surfactant transport in an oscillatory alveolus partially filled with liquid
(The American Institute of Physics, 2005-03)
The flow and transport in an alveolus are of fundamental importance to partial liquid ventilation, surfactant transport, pulmonary drug administration, cell-cell signaling pathways, and gene therapy. We model the system ...
The influence of beam model differences in the comparison of dose calculation algorithms for lung cancer treatment planning
(IOP Publishing Ltd, 2005-03-07)
In this study, we show that beam model differences play an important role in the comparison of dose calculated with various algorithms for lung cancer treatment planning. These differences may impact the accurate correlation ...
Controlling the motion of interacting particles: Homogeneous systems and binary mixtures
(The American Institute of Physics, 2005-06)
We elaborate on recent results on the transport of interacting particles for both single-species and binary mixtures subject to an external driving on a ratchetlike asymmetric substrate. Moreover, we also briefly review ...
Optical properties and structure characterization of sapphire after Ni ion implantation and annealing
(The American Institute of Physics, 2005-10-01)
Implantation of 64 keV64keV Ni ions to sapphire was conducted at room temperature to 1×1017 ions/cm21×1017ions∕cm2 with a current density of 55 or 10 μA/cm210μA∕cm2. Metallic Ni nanoparticles were formed with the 5 μA/cm25μA∕cm2 ...
Self-assembled morphologies of monotethered polyhedral oligomeric silsesquioxane nanocubes from computer simulation
(The American Institute of Physics, 2005-11-08)
Self-assembly of functionalized nanoscale building blocks is a promising strategy for “bottom-up” materials design. Recent experiments have demonstrated that the self-assembly of polyhedral oligomeric silsesquioxane (POSS) ...
Thin-film ferromagnetic semiconductors based on Sb2−xVxTe3Sb2−xVxTe3 with TCTC of 177 K177K
(The American Institute of Physics, 2005-09-12)
Thin-film ferromagnetic semiconductors Sb2−xVxTe3Sb2−xVxTe3 with the Curie temperature as high as 177 K177K were prepared on sapphire (0001) substrates by molecular-beam epitaxy. Films of Sb2−xVxTe3Sb2−xVxTe3 with xx up ...
1/f1∕f noise in gold nanoparticle chemosensors
(The American Institute of Physics, 2005-02-14)
We present a systematic study of low-frequency noise in Au nanoparticle chemosensors. All the sensors we have studied exhibit 1/f1∕f-type noise at low frequencies. The magnitude of the 1/f1∕f noise was smaller in devices ...
The effects of electrostatic forces on the distribution of drops in a channel flow: Two-dimensional oblate drops
(The American Institute of Physics, 2005-09)
Numerical simulations are used to examine the effect of an electrostatic field on an emulsion of drops in a channel. The leaky-dielectric theory of Taylor is used to find the electric field, the charge distribution on the ...
Shear softening and structure in a simulated three-dimensional binary glass
(The American Institute of Physics, 2005-04-15)
Three-dimensional model binary glasses produced by quenching from a range of liquid temperatures were tested in shear over a range of strain rates using molecular-dynamics techniques. Tests were performed under constant ...
On Travelling Waves for the Stochastic Fisher–Kolmogorov–Petrovsky–Piscunov Equation
(Kluwer Academic Publishers-Plenum Publishers; Springer Science+Business Media, Inc., 2005-08)
This paper is concerned with properties of the wave speed for the stochastically perturbed Fisher–Kolmogorov–Petrovsky–Piscunov (FKPP) equation. It was shown in the classical 1937 paper by Kolmogorov, Petrovsky and Piscunov ...
