F1 hybrids can outperform their parents in yield and vegetative biomass, features of hybrid vigor that form the basis of the hybrid seed industry. The yield advantage of the F1 is lost in the F2 and subsequent generations. In Arabidopsis, from F2 plants that have a F1-like phenotype, we have by recurrent selection produced pure breeding F5/F6 lines, hybrid mimics, in which the characteristics o...

improving mechanical properties of composites based on strength-to-weight ratio has been gained much attention in various applications. having the most resistant and at the same time the lightest and the most economical structure is believed as an aim in these applications. these three factors are usually opposed to each other. so, applying optimization algorithms for improving mechanical prope...

German cardinal numbers show variable stress patterns on the phonetic surface. Former studies showed that these cannot be explained by stress shift. In a combined production and perception study, the hypothesis is tested that German cardinal numbers are of a hybrid phonological nature: sentence medially, they behave like compounds following the CSR, while they behave like phonological phrases f...

Abstract Salix is a genus of considerable taxonomic complexity, and accurate identification its species hybrids not always possible. Quantification ovules was used in this study to verify the parentage few . It has been shown that ovule numbers willow are mean their parents. The index prostrate specimen S. ×cottetii affirmed hybrid myrsinifolia Salisb. retusa L., ornamental cultivar ‘The Hague’...

We consider a job shop problem with uncertain processing times modelled as triangular fuzzy numbers and propose a methodology to study solution robustness with respect to different perturbations in the durations. This methodology is applied to obtain experimental results for several problem instances, using a hybrid genetic algorithm that minimises the expected makespan. We conclude that taking...

Multi-periodic inventory control problems are mainly studied by employing one of two assumptions. First, the continuous review, where depending on the inventory level, orders can happen at any time, and next the periodic review, where orders can only be placed at the beginning of each period. In this paper, we relax these assumptions and assume the times between two replenishments are independe...

Since gluons in QCD are interacting fundamental constituents just as quarks are, we expect that in addition to mesons made from a quark and an antiquark, there should also be glueballs and hybrids (bound states of quarks, antiquarks and gluons). In general, these states would mix strongly with the conventional qq mesons. However, 1 Submitted to Physical Review D. they can also have exotic quant...

The aim of this paper is to define hyper-Leonardo hybrinomials as a generalization the Leonardo Pisano and examine some their properties such recurrence relation, summation formula generating function. Another introduce hyper hybrid-Leonardo numbers.

Hybrids between A9 (HGPRT-) and B82 (TK-), mouse heteroploid fibroblast lines, were obtained through continuous cultivation and clonal selection; such hybrids showed marked segregation and by conventional stains displayed chromosome numbers and distribution similar to that of either parental type. Detailed analyses by Giemsa (G)- and centromeric-banding of these parental lines, and of 4 of the ...

There are many situations for statistical process in which we have both random and vagueinformation. When uncertainty is due to fuzziness of information, fuzzy statistical control charts play animportant role in the monitoring process, because they simultaneously deal with both kinds of uncertainty.Dealing with fuzzy characteristics using classical methods may cause the loss of information and ...
