In the new species, the digestive apparatus displays a hexagonal peculiar aperture, followed by a longitudinal slit, a waved pharynx, two long and broad caeca, with a thick internal wall of endothelial cells. Each caecum has a sub terminal anus. The female genital apparatus displays a ...
a第三、系统语言学比较重视对个别语言以及个别变体的描写,并且认为这种描写本身就是语言学的目的之一,而不是为了发现语言的普遍现象。 Third, the system linguistics quite takes the individual language as well as the individual anomalous form description, and thought this kind describes itself is one of ...

The description of arbitrary shaped beams in elliptical cylinder coordinates is presented by using a plane wave spectrum approach. It is demonstrated and exemplified that this approach is equivalent to a formally more rigorous approach in terms of distributions. Beam shape coefficients are evaluated by...
摘要: Introduces two wavefunctions to describe a single relativistic free electron, from which the authors can obtain the value of an arbitrary physical quantity at any time t. They find that the motion of free electrons is the same as that given by special relativity....
This article is a tutorial exposition of the template approach to the construction of customized mass-stiffness pairs for selected applications in structur
of traveling wave or propagation structure. In this study, we sought to unify observed phenomena across these two categories in the form of three low-frequency spatiotemporal patterns composed of a mixture of standing and traveling wave dynamics. We showed that a range of empirical phenomena, ...
