Maps of large-scale biodiversity are urgently needed to guide conservation, and yet complete enumeration of organisms is impractical at present. One indirect approach is to measure richness at higher taxonomic ranks, such as families. The difficulty is how to combine information from different groups on numbers of higher taxa when these taxa may in effect have been defined in different ways, pa...

An important question in genome evolution is whether there exist fragile regions (rearrangement hotspots) where chromosomal rearrangements are happening over and over again. Although nearly all recent studies supported the existence of fragile regions in mammalian genomes, the most comprehensive phylogenomic study of mammals (Ma et al. (2006) Genome Research 16, 1557-1565) raised some doubts ab...

Basic Internet access is considered a human right, however geographical, technological and socio-economic reasons set barriers to universal Internet access. To address this challenge, we have proposed an access method based on message ferrying that enables free delay-tolerant Internet access to all, and developed Connectivity plAn Routing PrOtOcOL (CARPOOL), a reference routing protocol for the...

S ince 2008, the periphery of Europe has been suffering an economic contraction of a magnitude that in several countries is comparable to the US Great Depression. During the early 2000s, the periphery of Europe enjoyed rapid growth in domestic demand, wages, and employment. Much of this bonanza was fueled by large international capital infl ows. Figure 1 displays the current account, nominal ho...

This paper presents a novel region discovery framework geared towards finding scientifically interesting places in spatial datasets. We view region discovery as a clustering problem in which an externally given fitness function has to be maximized. The framework adapts four representative clustering algorithms, exemplifying prototype-based, gridbased, density-based, and agglomerative clustering...

As modern organizations increasingly operate in a global economy, they need IT support around the globe; favorable economic conditions also encourage the use of offshore IT teams. However, when IT efforts "go global," issues and challenges typical of IT development and support are magnified. In this paper, we review and integrate three research areas that contribute to our understanding and man...

The Mediterranean area is one of the most significantly altered hotspots on Earth, since it has been intensively affected by human activity for millennia. As a result, only 4.7% of its primary vegetation remained unaltered and the landscape has been repeatedly transformed. In this paper, we aimed at detecting both the direction and the rate of landscape change focusing on the effects of human a...

Executive Summary The growth in the number of Wi-Fi devices accessing the network in concentrated areas, along with limitations in shared spectrum, requires a new approach to provide the best predictable and scalable user experience. The goal of this white paper is to provide the technical details behind Cisco's unique approach to high-density Wi-Fi design, Cisco ® High Density Experience (HDX)...
