Background: Joint attention has received a lot of attention by researchers and specialists of autism spectrum disorder in recent years and refers to a developmental skill resulting in joining attention or processing messages of others. Defect in growth of joint attention is particular to children with autism spectrum disorder and is one of the symptoms for diagnosing autism spectrum disorder in...

 In this paper, we study the phonon thermal properties of a ladder nanostructure in harmonic approximation. We present a model consisting of two infinite chains with different masses. Then, we investigate the effect of different masses on the phonon spectrum. Moreover, as a specific case, in the absence of the second neighbor interaction, we calculate the phonon density of states/modes. Finally...
