We study a finite difference continuation (FDC) method for computing energy levels and wave functions of Bose–Einstein condensates (BEC), which is governed by the Gross–Pitaevskii equation (GPE). We choose the chemical potential λ as the continuation parameter so that the proposed algorithm can compute all energy levels of the discrete GPE. The GPE is(More)
Most of conventional RNA extraction methods failed to extract highly pure and integral RNA from peanut seeds because peanut seeds are extremely rich in lipids, proteins, polysaccharides, and phenolic compounds. Here, we describe a new method, named Peanut Improved Modified RNA extraction method (PIMRNAext), using SDS, Tris-saturated phenol, NaCl, and(More)
A sensitive and reliable method of liquid chromatography-electrospray ionization/tandem mass spectrometry (LC-ESI/MS/ MS) was developed and validated for determining 1,3-dimethylamylamine (1,3-DMAA) and 1,4-dimethylamylamine (1,4-DMAA) in geranium plants (Pelargonium graveolens). The sample was extracted with 0.5 M HCl and purified by liquid-liquid(More)
A plasma membrane Na+/H+ antiporter gene (CsSOS1) was separated from cucumber (Cucumis sativus L.) plants by RT-PCR and RACE methods. Sequence analysis indicated that the full-length CsSOS1 cDNA was 3638 bp long with an open reading frame of 3435 bp long encoding a protein of 1145 amino acids. The deduced protein contained conserved structural domains and(More)
Although peanut (Arachis hypogaea L.) is a relatively drought-tolerant crop, its productivity and quality is adversely affected by drought stress. The identification of novel genes, the analysis of gene expression patterns in response to dehydration stress, and the evaluation of their potential functions in stress adaptation will provide the basis for(More)
