In particular, every tangent cone at each isolated singularity of the resulting hypersurface is area-minimising. As a consequence, for any real \${$\backslash$}lambda\$ we show, through a surgery procedure, that for a generic 8-dimensional compact Riemannian manifold with positive Ricci curvature there exists a closed embedded smooth hypersurface of constant mean curvature \${$\backslash$}lambda\$; the minimal case (\${$\backslash$}lambda\$ = 0) of this result was obtained in work by Chodosh-Liokumovich-Spolaor.} }
