  The purpose of this paper is to introduce and study BiHom-NS-algebras, which
are a generalization of NS-algebras using two homomorphisms. Moreover, we
discuss their relationships with twisted Rota-Baxter operators in a
BiHom-associative context. Furthermore, we introduce a generalization of
Nijenhuis operators that lead to BiHom-NS-algebras along BiHom-associative
algebras
