Growth and properties of quasiperiodic heterostructures
(Elsevier, 1987-02-02)
We have recently demonstrated the MBE growth of heterostructures in which layers of GaAs and AlAs were deposited in a Fibonacci sequence. This yields a quasiperiodic structure with the ratio of incommensurate periods equal ...
Resonant energy transfer in electron-driven proton pumps
(WILEY-VCH Verlag, 2008-01)
We examine proton and electron transport in living cell membranes and show that the Coulomb interaction leads to a resonant energy transfer, from the electrons to protons during their simultaneous tunnelings, which allows ...
Functional clustering in hippocampal cultures: relating network structure and dynamics
(2010-10)
In this work we investigate the relationship between gross anatomic structural network properties, neuronal dynamics and the resultant functional structure in dissociated rat hippocampal cultures. Specifically, we studied ...
Cosmological Magnetohydrodynamic Simulations of Cluster Formation with Anisotropic Thermal Conduction
(IOP Publishing, 2011)
The intracluster medium (ICM) has been suggested to be buoyantly unstable in the presence of magnetic field and anisotropic thermal conduction. We perform first cosmological simulations of galaxy cluster formation that ...
Brane-world Kaluza–Klein reductions and branes on the brane
(The American Institute of Physics, 2001-07)
We present a systematic study of a new type of consistent “brane-world Kaluza–Klein reduction,” which describes fully nonlinear deformations of codimension one objects that arise as solutions of a large class of gauged ...
Tests of a large air‐core superconducting solenoid as a nuclear‐reaction‐product spectrometer
(The American Institute of Physics, 1987-09)
An air‐core superconducting solenoid, with a diameter of 0.2 m and a length of 0.4 m, has been configured for use as a heavy‐ion reaction‐product spectrometer (E/A≤5 MeV/u) near θ=0 °. The spectrometer has a large solid ...
Instability of Three‐Layer Viscous Stratified Flow
(The American Institute of Physics, 1969-12)
Instability of plane Couette flow of three superposed layers of fluids of different viscosity between two horizontal planes is investigated. It is found that there are two modes of disturbance dominated, respectively, by ...
Hyperfine structure in the red emission system of NbN
(The American Institute of Physics, 1975-10-01)
A detailed study of hyperfine structure observed in the 0,0 band of the 3Φ (aβ) →3Δ (aβ) system of NbN has shown that the secondary hyperfine effects observed in this structure are not due to a perturbation in the 3Δ state ...
Nonrandom alloying in In0.52Al0.48As/InP grown by molecular beam epitaxy
(The American Institute of Physics, 1987-03-09)
Anomalous behavior in Hall data of molecular beam epitaxial In0.52Al0.48As/InP for T≥400 K suggests the presence of alloy clustering. The relaxation time for alloy clustering has been determined and analysis of measured ...
