The native ranges and invasion histories of many marine species remain elusive due to a dynamic dispersal process via marine vessels. Molecular markers can aid in identification of native ranges and elucidation of the introduction and establishment process. The supralittoral isopod Ligia exotica has a wide tropical and subtropical distribution, frequently found in harbors and ports around the g...

This paper reviews the existing localization techniques and parameters in Wireless Sensor Networks (WSNs) and few schemes are discussed in term of Terrestrial WSNs. The fundamental differences between Underwater and Terrestrial WSN are highlighted. Furthermore, the paper analyzes the few existing aquatic localization schemes and presents a discussion in two parts including general localization ...

We establish a new outer bound for the capacity region of product broadcast channels. This outer bound matches Marton’s inner bound for a variety of classes of product broadcast channels whose capacity regions were previously unknown. These classes include product of reversely semi-deterministic and product of reversely more-capable channels. A significant consequence of this new outer bound is...

As far as many consumers and businessmen and women are concerned, increasingly wireline and wireless services, including those provided by terrestrial and satellite systems, are considered to be substitutes and sometimes complements, regardless of the laws and regulations applicable to them. At the same time, many writers and even government agencies (such as the FCC) have suggested that users ...

A public process has been in place in the United States for six years to establish an HDTV terrestrial broadcasting standard. The process, having moved through a planning phase, a competition phase, and an examination phase, has now entered a cooperation phase. Remarkable progress has been made — a testament to the process. During the next few months, the American digital HDTV terrestrial broad...
