In this paper, a layout dependent full-chip electroplating (ECP) topography model is developed based on the additive nature of the physics of the EP process. Two layout attributes: layout density, and feature perimeter sum are used to compute the post-ECP topography. Under a unified mechanism, two output variables representing the final topography: the(More)
In deep submicron feature sizes continue to shrink aggressively beyond the natural capabilities of the 193 nm lithography used to produce those features thanks to all the innovations in the field of resolution enhancement techniques (RET). With reduced feature sizes and tighter pitches die level variations become an increasingly dominant factor in(More)
We study the octilinear Steiner tree to evaluate the rectilinear Steiner tree based router. First, we give the worst and average case wirelength for rectilinear routing and octilinear routing for two terminals net. Next, we show the octilinear Steiner trees have smaller wirelength reduction for multiterminal net than that of rectilinear Steiner tree. Then,(More)
OBJECTIVE To describe the levels of inflammation and vascular endothelial activation in an Aboriginal community, and the relationship of these factors to coronary heart disease (CHD) risk factors and markers of nutritional quality. DESIGN AND PARTICIPANTS A cross-sectional survey of 95 women and 76 men participating in a chronic-disease prevention(More)
To determine whether genetic heterogeneity exists in patients with Graves' disease (GD), the cytotoxic T-lymphocyte associated 4 (CTLA-4) gene, which is implicated a susceptibility gene for GD by considerable genetic and immunological evidence, was used for association analysis in a Chinese Han cohort recruited from various geographic regions. Our(More)
Adiponectin, the adipose-derived hormone, plays an important role in the suppression of metabolic disorders that can result in type 2 diabetes, obesity, and atherosclerosis. It has been shown that up-regulation of adiponectin or adiponectin receptor has a number of therapeutic benefits. Given that it is hard to convert the full size adiponectin protein into(More)
BACKGROUND A link between uric acid (UA) levels and cardiovascular diseases has been previously reported. However, its importance as a risk factor is still controversial. This study sought to determine whether elevated serum uric acid levels are associated with cardiovascular disease (CVD) in middle-aged and elderly Chinese individuals. METHODS We(More)
OBJECTIVE The two major classes of antidiabetic drugs, sulfonylureas and metformin, may differentially affect macrovascular complications and mortality in diabetic patients. We compared the long-term effects of glipizide and metformin on the major cardiovascular events in type 2 diabetic patients who had a history of coronary artery disease (CAD). (More)
