Data mining is a widely used technology for various real-life applications of data analytics and important to discover valuable association rules in transaction databases. Interesting itemset plays an role many applications, such as market, e-commerce, finance, medical treatment. To date, algorithms based on frequent patterns have been studied, but there are few that focus infrequent or rare pa...

To complete the sparse sampling of linear frequency modulation (LFM) signals and estimate parameters, authors proposed an improved finite rate innovation (FRI) system to achieve goal. First build a mathematical model based on Z-transform, then they input LFM signal into modified FRI process output this model, which enables estimation parameters using only four points. The error final experiment...

In wind-pollinated plants, male-biased sex allocation is often positively associated with plant size and height. However, effects of size (biomass or reproductive investment) and height were not separated in most previous studies. Here, using experimental populations of monoecious plants, Ambrosia altemisiifolia, we examined (1) how male and female reproductive investments (MRI and FRI) change ...

A differential pattern in the RAPD profile of Eucalyptus F1 natural hybrids FRI-4 (E. terticornis x E. camaldulensis), FRI-5 (E. camaldulensis X E. tereticornis) and controlled reciprocal crosses FRI-14 (E. torelliana X E. citriodora) along with their parental combinations was assessed through Polymerase Chain Reaction using commercially available primers. After electrophoresis of PCR product t...

Allopolyploidy is formed by combining two or more divergent genomes and occurs throughout the evolutionary history of many plants and some animals. Transcriptome analysis indicates that many genes in various biological pathways, including flowering time, are expressed nonadditively (different from the midparent value). However, the mechanisms for nonadditive gene regulation in a biological path...

After a brief introduction to the morphological properties of FRI radio sources, we discuss the possibility that FRI jets are relativistic at their bases and decelerate quickly to non-relativistic velocities. From two-frequency data we determine spectral index distributions and consequently the ages of FRI sources. We show that in the large majority of cases synchrotron theory provides unambigu...

The floral inhibitor FLOWERING LOCUS C (FLC) is a crucial regulator of flowering time in Arabidopsis, and is positively regulated by the FRIGIDA (FRI) gene in late-flowering winter-annual accessions. In rapid-cycling accessions, FLC expression is suppressed by the autonomous floral-promotion pathway (AP); thus AP mutants contain high levels of FLC and are late flowering. Previous work has shown...
