Background: Coronary artery disease (CAD) is a multifactorial and heterogenic disease. Recently, genome-wide association studies have reported that rs1333040 (C/T) and rs1004638 (A/T) single nucleotide polymorphisms (SNPs) in the 9p21 locus have very strong association with CAD. This study aimed to examine these associations in Southwest of Iran. Methods: Blood samples were collected from 200 C...

The Screen-Grid Field Effect Transistor (SGrFET) is a planar MOSFET-type device with a gating configuration consisting of metal cylindrical fingers inside the channel perpendicular to the current flow. The SGrFET operates in a MESFET mode using oxide insulated gates. The multi-gate configuration offers advantages for both analog and digital applications, whilst the gate cylinder holes can be ex...

For the realization of modern integrated circuits new interconnect structures like through-silicon-vias and solder bumps, together with complex multilevel 3D interconnect structures are gaining importance. The application of these new structures unavoidably rises different reliability issues like thermal gradients, electromigration, and stressmigration. In this paper we apply state-of-the art T...

In order to develop a novel n-in-p radiation-tolerant silicon microstrip sensor with a p-stop structure, surface structures are systematically analyzed for variations in the width, position, and multiplicity of p-stops. With the help of technology CAD (TCAD) simulation, three dynamics are quantitatively investigated: the dependence of the electric potential of the p-stops on the width of the p-...

We present a methodology for characterization and optimization of SiGe HBTs from our 0.8 μm BiCMOS technology. It involves process calibration, device calibration employing two-dimensional device simulation, and automated Technology Computer Aided Design (TCAD) optimization. The simulation results show a very good agreement with experimental data. In particular, we perform an optimization of co...

from the plants nutrition view point, silicon has not been recognized as an essential element but its useful effects on growth and development of many plants have been reported. in order to study the effect of application of different silicon on the yield component of wheat, an experiment was conducted in the city torbat heidarieh located in razavi khorasan province. the experiment was performe...
