have edited this new book to reflect the present and future challenges in wireless technologies for vehicular ad hoc networks. New technologies are being developed for vehicular ad hoc networks, and these networks provide an efficient method for today's complex vehicle communications. Emerging vehicular ad hoc networks in the forms of Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I)...

Johannes Holtfreter (1901-1992)

Johannes Holtfreter [6] made important discoveries about the properties of the organizer [7] discovered by Hans Spemann [8]. Although he spent much time away from the lab over many years, he was a productive researcher. His colleagues noted that the time he spent away helped revitalize his ideas. He is credited with the development of a balanced salt medium to allow embryos to develop; the disc...

The Origins and Interpretation of the Prebisch-Singer Thesis

The Prebisch-Singer thesis is generally taken to be the proposition that the net barter terms of trade between primary products (raw materials) and manufactures have been subject to a long-run downward trend.

Transposable elements (TEs) are a dominant feature of most flowering plant genomes. Together with other accepted facilitators of evolution, accumulating data indicate that TEs can explain much about their rapid evolution and diversification. Genome size in angiosperms is highly correlated with TE content and the overwhelming bulk (>80%) of large genomes can be composed of TEs. Among retro-TEs, ...
