This paper presents a novel approach for the synthesis of dynamic CMOS circuits using Domino and Nora styles. As these logic styles can implement only non-inverting logic, conventional logic design approaches cannot be used for Domino/Nora logic synthesis. To overcome this problem, we have used a new concept called unate decomposition of Boolean functions. The unate decomposition expresses a ge...

We extend the classical Domino problem to any tiling of rhombus-shaped tiles. For subshift X edge-to-edge rhombus tilings, such as Penrose subshift, we prove that associated X-Domino is $$\varPi _1^0$$ -hard and therefore undecidable. It -complete when given by a computable sequence forbidden patterns.

conclusions accidents resulting in death, total disability, and partial disability impose a huge cost burden on society, whereas the employer will bear a relatively low cost. this is because of society’s health, treatment, and welfare systems available for treatment and rehabilitation of injured employees and their families. background occupational accidents represent one of the major problems ...

Static circuit gates are the standard circuit devices used to build the major parts of digital circuits. Dynamic gates, such as domino circuits, are only used in certain sections of the circuit where speed is critical. These gates achieve higher speed compared to static gates at the cost of reduced noise margins. We propose a novel gate structure that tries to improved noise margin when compare...

An NHC-catalyzed Michael/Michael/esterification domino reaction via homoenolate/enolate intermediates for the asymmetric synthesis of tetrasubstituted cyclopentanes bearing four contiguous stereocenters is described. A variety of α,β-unsaturated aldehydes and 2-nitroallylic acetates react well with good domino yields and high stereoselectivities.
