Von Neumann-Jordan constants in quasi-Banach spaces

We introduce the generalized von Neumann-Jordan constant of a quasi-Banach space X. Also, the quasi-Hilbert characteristic is introduced. An attempt has been made to investigate the relationship between them. At the end, a characterization of uniformly non-square is given.
