\begin{document}$ N=152 $\end{document} has been experimentally confirmed through high-precision mass measurements on nobelium (\begin{document}$ Z=102 $\end{document}) and lawrencium (\begin{document}$ Z=103 $\end{document}) isotopes. The experimental measurements on α-decay properties suggest that deformed doubly-magic nature of \begin{document}$ ^{270} $\end{document}Hs. However, the magic gaps in the superheavy region are generally expected to be fragile. In this study, we test the robustness of \begin{document}$ N=152 $\end{document} shell closure in \begin{document}$ N=152 $\end{document} isotones and \begin{document}$ Z=108 $\end{document} shell closure in Hs isotopes by employing an alternative approach where both theoretical analysis and available experimental data are required. Combined with existing experimental measurements on α-decay energies, it is determined that robust \begin{document}$ N=152 $\end{document} neutron shell persists at least in \begin{document}$ Z=101-105 $\end{document} isotopes, and robust \begin{document}$ Z=108 $\end{document} proton shell persists in Hs isotopes with \begin{document}$ N=159,160 $\end{document}. Additionally, the relativistic mean-field model is determined as unable to provide \begin{document}$ N=152 $\end{document} shell. Thus, the conclusion that robust \begin{document}$ N=152 $\end{document} shell exists at least in \begin{document}$ Z=101-105 $\end{document} isotopes, provides crucial benchmarks for constraining effective interactions suitable for superheavy nuclei in nuclear energy-density functional theory in future."> Robustness of <i>N</i>=152 and <i>Z</i>=108 shell closures in superheavy mass region -
