Ambiguous Role of Growth-Induced Defects on the Semiconductor-to-Metal Characteristics in Epitaxial VO2/TiO2 Thin Films
(2018)Controlling the semiconductor-to-metal transition temperature in epitaxial VO2 thin films remains an unresolved question both at the fundamental as well as the application level. Within the scope of this work, the effects ...

Artificial neural networks to investigate the significance of PAPPA and b-hCG for the prediction of chromosomal abnormalities
(2011)A systematic approach has been done, to investigate different neural network structures for the appraisal of the significance of the free b-human chorionic gonadotrophin (b-hCG) and the pregnancy associated plasma protein-A ...

Convergence of belief propagation algorithms on binary pairwise Gibbs random fields
(2011)In this paper, we study the convergence of belief propagation algorithms (BPAs) on binary pairwise Gibbs random fields (BP-GRFs). Exploiting the equivalence of BPA on the graph associated with BP-GRF and the corresponding ...

Reduction of spin injection efficiency by interface defect spin scattering in ZnMnSe/AlGaAs-GaAs spin-polarized light-emitting diodes
(2002)The effects of the interface microstructure on spin-injection efficiency in Zn1-xMnxSe/AlyGa1-yAs-GaAs spin-polarized light-emitting diodes (spin-LEDs) were studied. It was shown that the quantum well (QW) spin polarization ...

Strong paramagnetism and possible ferromagnetism in pure carbon nanofoam produced by laser ablation
(2005)We report the production of a hierarchically nanostructured magnetic carbon foam by high-repetition-rate laser ablation of glassy carbon in Ar. The clusters contain both sp2 and sp3 bonded carbon atoms. The material contains ...
