Whereas the atomic structure of surface of crystals is known to be distinct from that of bulk, experimental evidence for thickness-induced structural transitions in amorphous oxides is lacking. We report the NMR result for amorphous alumina with varying thickness from bulk up to 5 nm, revealing the nature of structural transitions near amorphous oxide surfaces/interfaces. The coordination envir...

We present a new neural network-based method of image processing for determining the local composition and thickness of III±V semiconductors in high resolution electron microscope images. This is of great practical interest as these parameters in ̄uence the electrical properties of the semiconductor. Neural networks suppress correlated noise from amorphous object covering and distinguish between...

Objectives: To characterize the variations in extracerebral layer (ECL) thickness that exists within a subject. Secondly, to compare these ECL thickness variations across a group of subjects at two standardized location (at the level of the anterior commissure (AC) & 20mm above the AC (AC+20mm)). Finally, the influence of these ECL variations on propagation of light using the Monte Carlo simula...

In the present work, thermo-electro vibration of the piezoelectric nanoplates resting on the elastic foundations using nonlocal elasticity theory are considered. In-plane and transverse displacements of the nanoplate have been approximated by six different modified shear deformation plate theories considering transverse shear deformation effects and rotary inertia. Moreover, two new distributio...
