Complex networked systems provide access to a variety of resources. There are standard resources as well as nomadic ones. Local access suffices for some whereas others are far off requiring distant access. Of each resource type multiple instances are accessible greatly differing in characteristics. A scalability measure is used to evaluate the extent to which the system manages to effectively u...

Until recently, studies examining the geographical distribution of insects in the Tuscan Archipelago have focused on paleogeography as the primary influence on species distributions. However, for flying insects such as Hymenoptera that may be able to disperse over water, current geographical location is likely to be more important in determining present distributions within the Archipelago. Her...

A whole new class of location-aware services may be envisaged by the deployment of a geographic location service for Internet hosts. We focus on a technique that relies on delay measurements and the exploitation of a possible correlation between geographic distance and network delay. Our investigation shows that such a correlation becomes stronger as connectivity becomes richer. Host locations ...

Weusedmicrosatellitemarkers to characterize the population structure ofCoptotermes gestroi (Wasmann), an economically important termite species in the tropics. Eighty-Þve colonies were sampled from seven countries (Malaysia, Thailand, Singapore, Indonesia, the Philippines, Taiwan, and the United States [Hawaii]). Ten to 20 workers per colony were genotyped using eight variable microsatellite lo...

Power lines, roadways, pipelines, and other physical infrastructure are critical to modern society. These structures may be viewed as spatial networks where geographic distances play a role in the functionality and construction cost of links. Traditionally, studies of network robustness have primarily considered the connectedness of large, random networks. Yet for spatial infrastructure, physic...

The collaboration of individuals across large geographic distances began some time ago, perhaps as far back as the 19th century, with the invention of the telegraph, due to its significant impact on communication (Teresko, 2000). Today, with the increased use of computers, the Internet, and the World Wide Web, electronic communication (e-communication), as well as electronic collaboration (e-co...
