Quantum cellular automata (QCA) is a new technology in nano metre scale to support nanotechnology. QCA is very effective in terms of high space density and power dissipation and will be playing a major role in the development of the Quantum computer with low power consumption and high speed. This paper describes the design and layout of a 2-bit ALU based on quantum-dot cellular automata (QCA) u...

BACKGROUND There are limited data on the frequency of and factors associated with quantitative coronary angiography (QCA)-defined longitudinal stent deformation (LSD) in various contemporary drug-eluting stents platforms. This study sought to evaluate the predictors of LSD and its long-term clinical implication. METHODS AND RESULTS A patient-level pooled analysis was performed with 7350 lesio...

As a core technique to quantitatively assess the stenosis severity of coronary arteries, quantitative analysis (QCA) is urgently supposed become more automated and intelligent, especially for regions lacking expertise technology. The existing QCA methods highly depend on manual operation, which time-consuming subject personal experience. This study innovatively proposes fully automatic workflow...

BACKGROUND This paper explores the value of qualitative comparative analysis (QCA) in public health research using the example of a pilot case management intervention for long-term incapacity benefit recipients. It uses QCA to examine how the 'health improvement' effects of the intervention varied by individual and service characteristics. METHODS Data for 131 participants receiving the inter...

The Cholesterol Lowering Atherosclerosis Study, a randomized angiographic clinical trial, demonstrated the beneficial effect of niacin/colestipol plus diet therapy on coronary atherosclerosis. Outcome was determined by panel-based estimates (viewed in both still and cine modes) of percent stenosis severity and change in native artery and bypass graft lesions. Computer-based quantitative coronar...

The fault-tolerance properties of the classical Quantum Cellular Automata (QCA) Majority gate, as well as the AND-gate, suffer from precision errors in inherent in manufacturing on a nanometer scale. Due to these implementation problems, a new approach for QCA was developed. A solution using multiple QCA cells in block configuration is an improvement but will may not work depending on the numbe...

The ultimate nanodevice is the “quantum dot” since that implies confinement in all three dimensions. Heretofore, no Boolean logic scheme has been proposed that is based on coupling of quantum dots. A team of researchers at the University of Notre Dame has devised and demonstrated the fundamental properties of a computing paradigm called “Quantum-dot Cellular Automata (QCA)” QCA could be accompl...

A Quantum Cellular Automaton (QCA) is a nanotechnology which is an attractive alternative for transistor based technologies in the near future. A new seven input majority gate in quantum dot cellular automata is proposed in this paper. The basic elements in QCA are majority and inverter gates, therefore using a majority gate with more inputs in QCA circuit will cause reduction in cell count, la...

Over the past 15 years, educational technologists have been dabbling with a research technique known as quantitative content analysis (QCA). Although it is characterized as a systematic and objective procedure for describing communication, readers find insufficient evidence of either quality in published reports. In this paper, it is argued that QCA should be conceived of as a form of testing a...

CMOS miniaturization limits have improved research on other advanced alternative technologies. Quantum Cellular Automata (QCA) is a nanometer scale technology that is one of these alternatives. Two principals have been introducedin the concept of Random Number Generator which are related to some physical occurrences or computational algorithms. In this paper we introduce a QCA circuit which is ...
