In view of the lack of research on electrical resistivity size effect, this paper studies the influence of vacancies on the electrical resistivity size effect of nanocrystalline metal based on the residual resistivity and statistical thermodynamics. The results show that the electrical resistivity and temperature have a linear relationship at the nanoscale… (More)
We demonstrate pigtailed, tapered microstructured optical fiber couplers for use with high-index, small mode-field diameter waveguides. We achieve adiabatic reduction in mode field dimensions to less than 2 /spl mu/m with low excess loss.
Measuring within-field variability is essential for precision farming, and remote sensing is an important tool to obtain the needed information. The objective of this study was to evaluate rice (Oryza sativa L., irrigated lowland rice) growth variability in Qixing farm considering different fields, management practice and cultivars using high resolution… (More)
