We use two methods of constructing the initial mass distribution, the traditional way and Monte Carlo simulation, to obtain integrated U - B, B - V,V-R and V-I
Several novel highly symmetric carbohydrates bearing a diacylhydrazine framework have been synthesized via a five-step procedure by utilizing D-glucose, D-galac
The authors establish operator-valued Fourier multiplier theorems on Triebel spaces on RN, where the required smoothness of the multiplier functions depends on
Fe(Ⅱ) complex Fe[HB(pz)3]2(compound 1, pz=pyrazole) and Ni(Ⅱ) complex Ni[HB(pz)3]2(compound 2) have been obtained by the reaction of MCI2(M=Fe and Ni) with Na
