A new 1-bit full adder (FA) cell illustrating low-power, high-speed, and a small area is presented by combination of transmission gate (TG), pass transistor logic (PTL), float techniques. Using the proposed cell, 4:2 compressor implemented its performance investigated under diverse circumstances voltage, temperature, driving. The process corners are evaluated through process-voltage-temperature...

application of quantum-dot is a promising technology for implementing digital systems at nano-scale.  quantum-dot cellular automata (qca) is a system with low power consumption and a potentially high density and regularity. also, qca supports the new devices with nanotechnology architecture. this technique works based on electron interactions inside quantum-dots leading to emergence of quantum ...

The regulation of quantal size through pre- rather than postsynaptic mechanisms has recently received considerable attention as a potential mechanism for plasticity. Vesicular transporters catalyze the filling of synaptic vesicles with transmitter and are thus potential substrates for such presynaptic regulation. In this issue of Neuron, Prado et al. pursue this line of investigation and show t...

In reading through the various preprints, I was struck by the fact that many were concerned with specific computer implementations of one kind or another. Unfortunately, there seems to be little discussion of the program-ing from the programmer's viewpoint. This is under standable in a congress of computational linguistics but, I feel, somewhat regrettable. Especially nce the reports of what ha...
