Many plant species, including important crops like wheat, are polyploids that carry more than two sets of genetically related chromosomes capable of meiotic pairing. To safeguard a diploid-like behavior at meiosis, many polyploids evolved genetic loci that suppress incorrect pairing and recombination of homeologues. The Ph1 locus in wheat was proposed to ensure homologous pairing by controlling...

Approximate ripple carry adders (RCAs) and carry lookahead adders (CLAs) are presented which are compared with accurate RCAs and CLAs for performing a 32-bit addition. The accurate and approximate RCAs and CLAs are implemented using a 32/28nm CMOS process. Approximations ranging from 4to 20-bits are considered for the less significant adder bit positions. The simulation results show that approx...

For estimating delay parameters appearing in the CDMA (Code Division Multiple Access) model, several authors have proposed subspace-based solutions. Unfortunately, these methods , for example the eigenvector-based multiple signal clas-siication (MUSIC) method may yield poor results in noisy conditions. In this paper, we introduce subspace type delay estimation algorithms which are more eecient ...
