Emerging 3D die-stacked DRAM technology is one of the most promising solutions for future memory architectures to satisfy the ever-increasing demands on performance, power, and cost. This paper introduces CACTI-3DD, the first architecture-level integrated power, area, and timing modeling framework for 3D die-stacked off-chip DRAM main memory. CACTI-3DD(More)
This paper introduces CACTI-P, the first architecture-level integrated power, area, and timing modeling framework for SRAM-based structures with advanced leakage power reduction techniques. CACTI-P supports modeling of major leakage power reduction approaches including power-gating, long channel devices, and Hi-k metal gate devices. Because it accounts for(More)
Automated detection of blood vessel structures is becoming of crucial interest for better management of vascular disease. In this paper, we propose a new infinite active contour model that uses hybrid region information of the image to approach this problem. More specifically, an infinite perimeter regularizer, provided by using L(2) Lebesgue measure of the(More)
Semi-supervised learning concerns the problem of learning in the presence of labeled and unlabeled data. Several boosting algorithms have been extended to semi-supervised learning with various strategies. To our knowledge, however, none of them takes all three semi-supervised assumptions, i.e., smoothness, cluster, and manifold assumptions, together into(More)
Erythropoiesis is the process by which nucleated erythroid progenitors proliferate and differentiate to generate, every second, millions of nonnucleated red cells with their unique discoid shape and membrane material properties. Here we examined the time course of appearance of individual membrane protein components during murine erythropoiesis to throw new(More)
We propose a method for image segmentation based on a neural oscillator network. Unlike previous methods, weight adaptation is adopted during segmentation to remove noise and preserve significant discontinuities in an image. Moreover, a logarithmic grouping rule is proposed to facilitate grouping of oscillators representing pixels with coherent properties.(More)
Human umbilical-cord-derived mesenchymal stem cells (hUC-MSCs) constitute an attractive alternative to bone-marrow-derived MSCs for potential clinical applications because of easy preparation and lower risk of viral contamination. In this study, both proliferation of human peripheral blood mononuclear cells (hPBMCs) and their IFN-gamma production in(More)
