The use of quantum-dots is a promising emerging technology for implementing digital systems at the nano-scale level. Recently studied computational paradigms for quantum-dot technology include the use of locally connected quantum-dot cellular automata (QCA). This technique is based on the interaction of electrons within quantum dots that take advantage of quantum phenomena; the same phenomena t...

Transmembrane lipid translocation (flip-flop) processes are involved in a variety of properties and functions of cell membranes, such as membrane asymmetry and programmed cell death. Yet, flip-flops are one of the least understood dynamical processes in membranes. In this work, we elucidate the molecular mechanism of pore-mediated transmembrane lipid translocation (flip-flop) acquired from exte...

Dynamics of nuclear spin decoherence and nuclear spin flip-flops in self-assembled InGaAs/GaAs quantum dots are studied experimentally using optically detected nuclear magnetic resonance (NMR). Nuclear spin-echo decay times are found to be in the range 1-4 ms. This is a factor of ~3 longer than in strain-free GaAs/AlGaAs structures and is shown to result from strain-induced quadrupolar effects ...

In this paper, I explore sequential approaches to triangular matrix inversion (TMI). TMI is commonly performed when calculating the explicit inverse of a (dense) matrix from its LU factorization (cf. LAPACK xGETRI). Direct algorithms perform 13n 3 +O � n � flops, where the lower order terms depend on the specific implementation. Because of the structural relationship between a triangular matrix...

BACKGROUND Existing epidemiological studies of the association between oxidative stress and erectile dysfunction (ED) are sparse and inconclusive, which is likely due to cross-sectional design and small sample size. Therefore, we investigated the association between biomarkers of oxidative stress and ED in prospective setting among a relatively large sample size of men. METHODS We conducted t...

With the evolution of the semiconductor industry and the continuous growing demands for high performance VLSI circuit, the aggressive scaling in feature size and high integration density along with the high operating frequencies make power consumption and digital noise in modern analog and digital devices one of the top concerns of Very Large Scale Integration (VLSI) circuit design. In this pap...

The past decades witness FLOPS (Floating-point Operations per Second), as an important computation-centric performance metric, guides computer architecture evolution, bridges hardware and software co-design, and provides quantitative performance number for system optimization. However, for emerging datacenter computing (in short, DC) workloads, such as internet services or big data analytics, p...

-This paper proposes a low-power and area-efficient shift register using digital pulsed latches. The area and power consumption are reduced by replacing flip-flops with pulsed latches. This method solves the timing problem between pulsed latches through the use of multiple non-overlap delayed pulsed clock signals instead of the conventional single pulsed clock signal. The shift register uses a ...

The ability to store and to act upon modest amounts of information within living systems would enable new approaches to the study and control of biological processes. We develop a hierarchical composition framework supporting the design and analysis of higher-order genetically encoded information storage systems using combinatorial counters as a test case. We first develop a set-reset latch des...

During post-silicon validation, manufactured integrated circuits are extensively tested in actual system environments to detect design bugs. Bug localization involves identification of a bug trace (a sequence of inputs that activates and detects the bug) and a hardware design block where the bug is located. Existing bug localization practices during post-silicon validation are mostly manual and...
