This work is concerned with approximating a trivariate function defined on tensor-product domain via evaluations. Combining tensorized Chebyshev interpolation Tucker decomposition of low multilinear rank yields approximations that can be computed and stored very efficiently. The existing Chebfun3 algorithm [Hashemi Trefethen, SIAM J. Sci. Comput., 39 (2017)]uses similar format but the construct...

A hydroponic trial was carried out to investigate the effect of molybdenum (Mo) on uptake of phosphorus (P) in different rice cultivars. The experiment was conducted using a randomized complete-block design, with a split-plot arrangement of treatments and three replications. Four rates of Mo (0, 0.01, 0.1 and 1 mg L) and five cultivars (MR219, HASHEMI, MR232, FAJRE and MR253) provided the main ...

cold stress during the beginning of the season usually causes damage to rice plants in the north of iran. in this study, the expression of four genes namely osp5cs2, osttp1, oscoin and oslti6a, was studied in 14-day-old seedlings of a cold tolerance pr genotype and a cold sensitive hashemi variety during cold stress (5°c for 24h) by means of differential display method. pcr products were quanti...

High planting density affects the morphology and productivity of many crop species. Our objectives were to examine the phenotypic and transcriptomic changes that occur during plant density stress in barley (Hordeum vulgare L.) and maize (Zea mays L.) seedlings. In maize and barley seedlings, density stress impacted several morphological traits. Gene expression profi les were examined in four ba...
