Coulomb Drag in the Extreme Quantum Limit [PDF]

open access: yes, 1997
Coulomb drag resulting from interlayer electron-electron scattering in double layer 2D electron systems at high magnetic field has been measured. Within the lowest Landau level the observed drag resistance exceeds its zero magnetic value by factors of ...

Impacts of micro-size PbO on the gamma-ray shielding performance of polyepoxide resin

open access: yese-Polymers, 2023
A series of polyepoxide resins doped by lead oxide with low concentrations were fabricated in order to study the impacts of low PbO concentrations on the fabricated composites’ physical- and radiation-shielding properties.

Growth of ZnO thin films on GaAs by pulsed laser deposition [PDF]

open access: yes, 1995
ZnO thin films have been grown on GaAs substrates using the pulsed laser deposition technique with or without a photodeposited SiO2 buffer layer. The presence of the SiO2 layer has a beneficial effect on the crystalline quality of the grown ZnO films ...

Impact of WO3 and BaO nanoparticles on the radiation shielding characteristics of polydimethylsiloxane composites

open access: yese-Polymers, 2023
In this study, we developed flexible composites using silicone rubber (SR) or polydimethylsiloxane as the matrix and WO3 and BaO nanoparticles as filler to analyze their radiation-shielding performance. The linear attenuation coefficient (LAC) values for

Radiation shielding potential of ultra-high strength concrete from agro-industrial waste [PDF]

open access: yesNuclear Technology and Radiation Protection
Ultra-high strength concrete produced with agro-residual wastes and industrial by-products were tested for radiation shielding capacity by measuring the linear attenuation coefficient, half value layer and tenth value layer.

Resource-constrained classification using a cascade of neural network layers [PDF]

open access: yes, 2015
Deep neural networks are the state of the art technique for a wide variety of classification problems. Although deeper networks are able to make more accurate classifications, the value brought by an additional hidden layer diminishes rapidly.

Entanglement Spectrum and Entanglement Thermodynamics of Quantum Hall Bilayers at nu=1 [PDF]

open access: yes, 2011
We study the entanglement spectra of bilayer quantum Hall systems at total filling factor nu=1. In the interlayer-coherent phase at layer separations smaller than a critical value, the entanglement spectra show a striking similarity to the energy spectra

Ferrodistortive instability at the (001) surface of half-metallic manganites [PDF]

open access: yes, 2007
We present the structure of the fully relaxed (001) surface of the half-metallic manganite La0.7Sr0.3MnO3, calculated using density functional theory within the generalized gradient approximation (GGA).
