The study was performed between April 2005 and October 2006. After fulfilling the certain inclusion criteria, obtained data were recorded in a structured questionnaire. 18 FMTP sites and 6 control sites were examined by standardized manual tender point survey system. Systemic lupus erythematosus disease activity index (SLEDAI) was used covering all 9 organs and 24 descriptors with pre assigned severity weights. The scores ranged from 0 ( no disease activity) to 105 ( maximum disease activity). Both the SLE cases ...

As most of human activities involve eyes, eye movement features detection is very important, particularly in ubiquitous computing and smart human computer interfaces. We all are familiar with Eye movement features detection techniques that involves image or video processing. But in this work we concentrated on a relatively new eye movement features detection technique that uses electrostatic potential from eyes, also known as Electrooculography signal. The work includes the detailed signal processing steps necessary to detect the various eye movement features from the raw Electrooculography signal. The detection process is simple and improved compared to previous counterparts. The detection process is user independent and thus free of any calibration problems.

In this review, we overview the fundamental properties of plasmons in materials with various dimensionalities and discuss the optical functional properties of localized plasmon polaritons in nanometer-scale to atomic-scale objects. First, the pioneering works on plasmons by electron energy loss spectroscopy are briefly surveyed. Then, we discuss the effects of atomistic charge dynamics on the dispersion relation of propagating plasmon modes, such as those for planar crystal surface, atomic sheets and straight atomic wires. Finally, standing-wave plasmons, or antenna resonances of plasmon polariton, of some widely used nanometer-scale structures and atomic-scale wires (the smallest possible plasmonic building blocks) are exemplified along with their applications.

The vertically stacked, Au nano-disks of three different sizes make it possible to merge the individual spectral windows of the internal nano-disks into one broadband window, and can be simply generated by a single-step electron-beam lithography step with subsequent sputter deposition.
