Faculty of Mathematics and Natural Sciences, Department of Theoretical Physics, Theoretical and Computational Physics Lab., Pattimura University, Ambon, Indonesia ABSTRACT Two types of integrable coupled nonlinear Schrödinger (NLS) equations are derived by using Zakharov-Shabat (ZS) dressing method.The Lax pairs for the coupled NLS equations are also investigated using the ZS dressing method. T...

Let E/Q be an elliptic curve of rank 1. We describe an algorithm which uses the value of L′(E, 1) and the theory of canonical heghts to efficiently search for points in E(Q) and E(ZS). For rank 1 elliptic curves E/Q of moderately large conductor (say on the order of 107 to 1010) and with a generator having moderately large canonical height (say between 13 and 50), our algorithm is the first pra...

I am writing in regards to an inaccuracy in the recent case report published in the Journal of Community Hospital Internal Medicine Perspectives by Karmacharya et al. (1). The authors had stated that sodium zirconium cyclosilicate (ZS-9) along with patiromer sorbitex calcium (patiromer) has not been studied in patients with serum potassium (K ) concentrations 6.5 mEq/L. However, it should be no...

cadmium (cd), known as a non-essential heavy metal, can cause oxidative stress in plants. in this study, an attempt was carried out to find out whether cd-induced oxidative and microscopic changes could be observed in the early stage of seedling growth. seeds of brassica napus (cvs. zheda 619 and zs 758) were germinated in vitro at 0, 100, 200, 300, and 500 μm cd concentrations in dark for 48 h...

The frequency of giant arcs— highly distorted and strongly gravitationally lensed background galaxies— is a powerful test for cosmological models. Previous comparisons of arc statistics for the currently favored concordance cosmological model (a flat lambda-dominated universe) with observations have shown an apparently large discrepancy. We present here new ray-shooting results, based on a high...
