Heterospecific eavesdropping on disturbance cues of a treefrog

Animal Cognition - Alarm signals and cues are crucial to animal survival and vary greatly across species. Eavesdropping on heterospecific alarm signals and cues can provide eavesdroppers with...     

Green's functions of magnetoelectroelastic solids with a half-plane boundary or bimaterial interface

Green's functions for magnetoelectroelastic medium with an arbitrarily oriented half-plane or bimaterial interface are presented in this paper. The derivation is based on an extended Stroh's formalism and coordinate-transform technique. In particular, a new coordinate variable is introduced to handle vertical or other boundary problems. These Green's functions satisfy related boundary or interface conditions. The Green's functions obtained can be used to establish boundary-element formulation and to analyse fracture behaviour involving half-plane boundaries or bimaterial interfaces.
