We discover that the spectral singularity's primary gain level for triggering the spectral singularity is determined by the coupling strength of various parts of the device. We can demonstrate the spectral singularity of the proposed structure at a very low gain level, which would bring active metamaterials systems a step closer to their practical implementation. We can show the spectral singularity of the proposed structure at a relatively low gain level by optimizing the coupling coefficients between various components.

To determine contact load assignments, two pair of conical contact is regarded as the intersection between a finite stiffness punch and an elastic half-plane. An analytic model is established to obtain the contact pressure distribution on each conical contact interface based on the findings of contact load assignments, considering the capsizing time and stress singularity at the end of the contact interface.

According to Tafarrud of a prophetic tradition, hadith reported by a single narrator at some stage of the chain of narrators. This paper examines Imam Al-Bazzar's involvement in dealing with tafarrud of prophetic traditions in a later stage of chain of narrators' behavior and its effects on the decision of hadith.
