A new underground industry has emerged where people are buying raw compounds for Ozempic, Botox, filler and skin-tightening treatments directly from Chinese suppliers — and injecting them at ...

Abstract: Recently, analog matrix inversion circuits (INV) have demonstrated significant advantages in solving matrix equations. However, solving large-scale sparse tridiagonal linear systems (TLS) ...

Abstract: In the field of operator equations, solving the inner inverses is essential. In this paper, based on the Lagrangian function a class of block Gauss-Seidel methods is proposed, which contains ...
