Quantum-dot cellular automata (QCA) has been advocated as a promising emerging nanotechnology for designing future nanocomputing systems. However, at device level, the large number of expected defects represents a significant hurdle for reliable computation in QCA-based systems. In this paper, we present an information-theoretic approach to investigate the(More)
Write-through policy employed in many high-performance microprocessors provides good tolerance to soft errors in cache systems. However, it also incurs large energy overhead due to the increased accesses to caches at the lower level (e.g., the L2 cache) during write operations. In this paper, we propose a new cache architecture referred to as <i>way-tagged(More)
Molecular electronics such as silicon nanowires (NW) and carbon nanotubes (NT) are considered to be the fabric of next generation nanocomputing. However, the excessive defects caused by bottom-up self-assembly fabrication have become a fundamental obstacle for achieving reliable computation in molecular systems. In this paper, we present an(More)
Exposure to concentrated ambient fine particulate matter (PM2.5) has been associated with cardiovascular diseases (CVDs). The barrier function of vascular endothelial cells is critical for the development of CVDs. Here, we employed human umbilical vein endothelial cells to clarify the function of ambient PM2.5 pollution in the regulation of membrane(More)
Nano/molecular technologies have emerged as the potential fabrics for building future integrated systems. However, due to the imperfect fabrication process, these extremely scaled devices are vulnerable to a large number of defects and transient faults. Memory systems, which are the primary application targeted by these technologies, are particularly(More)
