A new comparison of the $F_{2}^{A}/F_{2}^{p}$ and $F_{2}^{A}/F_{2}^{n}$ structure function ratios $\backslash $\textbf{f1}

h $-abstract-$\backslash $pardUsing electron scattering data from SLAC E139 and muon scattering data from NMC in the DIS region, we determine the $F_{2}^{A}/F_{2}^{p}$ and $F_{2}^{A}/F_{2}^{n}^{\mathrm{\thinspace }}$structure function ratios, spanning 0.07 le $x_{B}$ le 0.7 and 1 le $Q^{2}$ le 200 GeV/c$^{\mathrm{2}}$ and 0.006 le $x_{B}$ le 0.6 and 1 le $Q^{2}$ le 55 GeV/c$^{\mathrm{2}}$, respectively. This region is of particular relevance to studies of EMC Effect. Assuming no $Q^{2}$ dependence, we compare the structure function ratios for isoscalar nuclei and study non-isoscalar nuclei with the possibility to look for flavor dependence. This talk will present the results of the mentioned ratios for isoscalar nuclei using the new $F_{2}^{n}$ global data from the CTEQ-JLab Collaboration.$\backslash $pard-/abstract-$\backslash $\tex
