A new algorithm for calculating quaternary Fixed-Polarity Reed–Muller (FPRM) spectra is described in this paper. The presented algorithm directly converts array of disjoint cubes representation of a quaternary function into its FPRM spectral coefficients. The main advantage of this algorithm is that it requires less memory space than other algorithms. Since each spectral coefficient can be calc...

In 1916 Jacobs, Heidelberger, and coworkers at the Rockefeller Institute reported the discovery of a new class of synthetic compounds which possessed potent bactelicidal properties. By reacting hexamethylenetetramine with a large variety of substituted benzylor alkyl-halides, nujmerous quaternary salts of this base were obtained. It was observed that most of these salts had pronounced bacterici...

The crystal structure of the title compound, C(11)H(18)O(6)S(2), was determined to investigate the effect of the eclipsed mesyl groups on the bond length of the vicinal quaternary C atoms. The two quaternary C atoms of the noradamantane skeleton and the two O atoms to which they are connected all located essentially in the same plane [maximum deviation 0.01 Å], resulting in an eclipsing conform...

Multiple Valued Logic (MVL) has some important benefits such as increased data density, increased computational ability, reduced dynamic power dissipation Therefore with the help of Multiple Valued Logic (MVL) we have designed two quaternary multiplier architecture. The partial products in the multiplier are designed with quaternary voltage mode circuits. Each multiplier architecture is designe...

The crystal structure of the title compound, C(9)H(12)O(4)S, was determined in order to investigate the effect of the eclipsed O atoms on the bond length of the vicinal quaternary C atoms. The two quaternary C atoms of the noradamantane skeleton and the two O atoms to which they are connected all located essentially in the same plane (maximum deviation = 0.01 Å), resulting in an eclipsed confor...

All-carbon quaternary stereocenters have posed significant challenges in the synthesis of complex natural products. These important structural motifs have inspired the development of broadly applicable palladium-catalyzed asymmetric allylic alkylation reactions of unstabilized non-biased enolates for the synthesis of enantioenriched α-quaternary products. This microreview outlines key considera...

This paper presents arithmetic operations like addition, subtraction and multiplications in Modulo-4 arithmetic, and also addition, multiplication in Galois field, using multi-valued logic (MVL). Quaternary to binary and binary to quaternary converters are designed using down literal circuits. Negation in modular arithmetic is designed with only one gate. Logic design of each operation is achie...
