We study a recently introduced and exactly solvable mean-field model for the density of vibrational states $\mathcal{D}(\ensuremath{\omega})$ structurally disordered system. The is formulated as collection anharmonic oscillators, with random stiffness $\ensuremath{\kappa}$ drawn from distribution $p(\ensuremath{\kappa})$, subjected to constant field $h$ interacting bilinearly coupling strength ...

The multi-scale finite element method is used to study the vibrational characteristics of polymer matrix reinforced by single-walled silicon carbide nanotubes. For this purpose, the nanoscale finite element method is employed to simulate the nanotubes at the nanoscale. While, the polymer is considered as a continuum at the larger scale. The polymer nanotube interphase is simulated by spring ele...

Interfaces of liquid water play a critical role in a wide variety of processes that occur in biology, a variety of technologies, and the environment. Many macroscopic observations clarify that the properties of liquid water interfaces significantly differ from those of the bulk liquid. In addition to interfacial molecular structure, knowledge of the rates and mechanisms of the relaxation of exc...

Communication by substrate-borne mechanical signals is widespread among animals but remains one of their least understood communication channels. Past studies of vibrational communication in insects have been oriented predominantly to communication during mating, showing that species- and sex-specific vibrational signals enable recognition and localization of potential mates on continuous solid...
