Animal communication is affected by a multitude of environmental factors including meteorological conditions, ground reflection, turbulence, and vegetative attenuation. Evolutionary and behavioral adaptations by animals to these challenges include elephant use of infrasound optimized for long-distance propagation. These adaptations in turn influence the perceptual sphere, or Umwelt, of calling animals. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

In this paper we present a novel approach for realizing an integrated all-optical logic gate. The basic principle is based upon stimulated emission process generated in an active gain medium while special interferometric photonic wave-guiding structure allows the realization of an integrated micro scale device. The operation rate of the proposed device structure can theoretically reach tens of Tera-Hertz. 相似文献
