Conventionally, signal net routing is almost always implemented asSteiner trees. However, non-tree topology is often superior on timing performance as well as tolerance to open faults and variations. These advantages are particularly appealing for timing critical net routings in nano-scale VLSI designs where interconnect delay is a performance bottleneck(More)
— Conventionally, the topology of signal net routing is almost always restricted to Steiner trees, either unbuffered or buffered. However, introducing redundant paths into the topology (which leads to non-tree) may significantly improve timing performance as well as tolerance to open faults and variations. These advantages are particularly appealing for(More)
We first demonstrate the rational design and fabrication of novel atomically thick Co3O4 nanosheets (ATCNs) with a specific facet exposed by topochemical transformation from layered intermediate precursors to optimize energy storage. The eminently enhanced lithium storage performance can be attributed not only to the synergistic advantages of inorganic(More)
BACKGROUND The purpose of this study was to define the ultrasound imaging characteristics of adrenal tumors and to assess the performance of ultrasound in differentiating benign 'leave-alone' lesions from suspicious lesions. MATERIAL AND METHODS We enrolled 882 patients in this study. The nature of each lesion was determined by histopathology. Ultrasound(More)
The long-term outcomes of ultrasound-guided high-intensity focused ultrasound (USgHIFU) ablation treatment for adenomyosis and the relevant factors affecting the durability of symptom relief were assessed in this study.A total of 230 women with adenomyosis who were treated with USgHIFU ablation between January 2007 and December 2013 were retrospectively(More)
A three dimensional (3-D) capacitance extraction algorithm based on a kernel independent hierarchical method and geometric moments is described. Several techniques are incorporated, which leads to a better overall performance for arbitrary interconnect systems. First, the new algorithm hierarchically partitions the bounding box of all interconnect panels to(More)
