This paper examines jump dynamic patterns in three Chinese medical stocks. It also compares the Value-at-Risk (VaR) forecasting performance of a newly proposed realized volatility model allowing for jumps with that of two commonly used realized volatility models, which do not account for jumps. Using the Heterogeneous Autoregressive Realized Volatility model that allows for jumps (HAR-CJN), we ...
In this paper, a single-mask substrate transfer process for the fabrication of high-aspect-ratio (HAR) suspended structures is presented. The HAR silicon structures are fabricated using a deep reactive ion etching (DRIE) technique and then transferred to a glass wafer using silicon/thin film/glass anodic bonding and silicon thinning techniques. The HAR structures are released using self-aligned...
Sustained increases in glucose flux via the aldose reductase (AR) pathway have been linked to diabetic vascular complications. Previous studies revealed that glucose flux via AR mediates endothelial dysfunction and leads to lesional hemorrhage in diabetic human AR (hAR) expressing mice in an apoE(-/-) background. Our studies revealed sustained activation of Egr-1 with subsequent induction of it...
Porphyromonas gingivalis is a Gram-negative anaerobic bacterium that has an absolute requirement for iron which it transports from the host as heme and/or Fe(2 +). Iron transport must be regulated to prevent toxic effects from excess metal in the cell. P. gingivalis has one ferric uptake regulator (Fur) orthologue encoded in its genome called Har, which would be expected to regulate the transpo...
