Non-Hermitian models with real eigenenergies are highly desirable for their stability. Yet, most of the currently known ones constrained by symmetries such as PT-symmetry, which is incompatible realizing some exotic non-Hermitian phenomena. In this work, we investigate how skin effect provides an alternative route towards enforcing spectra and system We showcase, different classes energy disper...

Over the last 100 years, many theories have attempted to explain the cause of malocclusion. Most have stated that it is inherited, but, more recently, greater emphasis has been placed on the influence of the environment, especially the activity and the posture of the oral soft tissues. Unfortunately, it is not possible to measure long-term posture with any precision, and this has reduced its pe...
