This study describes the fabrication of two types of multilayered coatings onto titanium by electrostatic self-assembly (ESA), using deoxyribosenucleic acid (DNA) as the anionic polyelectrolyte and poly-d-lysine (PDL) or poly(allylamine hydrochloride) (PAH) as the cationic polyelectrolyte. Both coatings were characterized using UV-vis spectrophotometry, atomic force microscopy (AFM), X-ray phot...

this article gives an approach to predict the springbackward phenomena during post solidification cooling in a functionally graded hybrid composite cylindrical shell with transverse isotropic structure. here the material properties are considered to be given with a general parabolic power-law function. during theoretical analysis, appropriate transform is introduced in the equilibrium equation ...

Iterative gradient methods such as Levenberg-Marquardt (LM) are in widespread use for source localization from electroencephalographic (EEG) and magnetoencephalographic (MEG) signals. Unfortunately, LM depends sensitively on the initial guess, necessitating repeated runs. This, combined with LM's high per-step cost, makes its computational burden quite high. To reduce this burden, we trained a ...

Most Particle Induced X-ray Emission (PIXE) data analysis codes are not focused on handling multilayered samples. We have developed an open-source library called ”LibCPIXE”, for PIXE data analysis. It is written in standard C and implements functions for simulating X-ray yields of PIXE spectra taken from arbitrary samples, including multilayered targets. The library is designed to be fast, port...

SUMMARY. There is controversy as to whether oxynto-cardiac mucosa (OCM), cardiac mucosa (CM) and intestinal metaplasia (IM) found in the gastroesophageal-junction region line the anatomic stomach, esophagus or both. A total of 785 retroflex biopsies taken at the endoscopic gastroesophageal junction in 244 patients were evaluated for the presence of gland ducts and multilayered epithelium which ...

OBJECTIVES To investigate practicing physicians' preferences, perceived usefulness and understanding of a new multilayered guideline presentation format-compared to a standard format-as well as conceptual understanding of trustworthy guideline concepts. DESIGN Participants attended a standardised lecture in which they were presented with a clinical scenario and randomised to view a guideline ...

Multilayered feed-forward neural networks trained with back-propagation algorithm are one of the most popular “online” artificial neural networks. These networks are showing strong inherit parallelism because of the influence of high number of simple computational elements. So it is natural to try to implement this kind of parallelism on parallel computer architecture. The Parallel Hybrid Ring ...

The microstructure and tensile response of amorphous ZrCu and nanocrystalline Cu multilayered thin films, with sharp or graded interfaces, are examined and analyzed. The extracted tensile properties of the multilayered films can be compared with the predicted values based on the iso-strain Rule of Mixture model. The multilayered films with graded interfaces, each about 50 nm thick, consistently...
