Let X be a geometrically irreducible smooth projective curve, defined over R, of genus at least two that admits nontrivial automorphisms. Fix a nontrivial automorphism σ of X. Assume that X does not have any real points. Then σ acts trivially on the set of all real theta characteristics of X if and only if X is hyperelliptic with σ being the unique hyperelliptic involution of X. Examples are gi...

Calcium fluoride nanoparticles doped with thulium and cerium were synthesized as a novel nanostructure by using the hydrothermal method. The prepared samples were characterized by X-ray diffraction (XRD) and energy dispersive spectrometer (EDS). The crystallite size of about 36 nm was estimated employing Scherer’s formula. Its shape and size were also observed by scanning electron microscope (...

Introduction: Surveying the growth and development of children is an important parameter in their health assessment. Since the growth affecting agents vary in countries, it is not sensible considering a unique growth chart for all. In this research, we have studied the growth chart of children from birth to month 24 in Bandar Abbas with regard to the standard growth curve. Methods: In this des...

Engine mathematical model can be used to simulate vehicle dynamic performance and fuel economy for vehicle design. Simulation of vehicle dynamic performance and fuel economy is based on mathematical model of engine. Least square method and multiple regression analysis were used to fit curve of external characteristics and universal characteristics when the test data of external characteristics ...
