Scythians were nomadic and semi-nomadic people that ruled the Eurasian steppe during much of the first millennium BCE. While having been extensively studied by archaeology, very little is known about their genetic identity. To fill this gap, we analyzed ancient mitochondrial DNA (mtDNA) from Scythians of the North Pontic Region (NPR) and successfully retrieved 19 whole mtDNA genomes. We have id...

The pervasive nature of multimedia recording devices enables novel pervasive multimedia applications with automatic, inexpensive, and ubiquitous identification and locationing abilities. We present the design and implementation of Ferret, a scalable system for locating nomadic objects augmented with RFID tags and displaying them to a user in real-time. We present two alternative algorithms for ...

As the number of public displays in the environment increases, new opportunities open up to improve situated interaction and to enable new kinds of applications. In order to make distributed display resources available to nomadic users, a key issue to address is how control can be dynamically shared between display users. It is important to study how control over a shared display can be acquire...

Artificial selection is the selection of advantageous natural variation for human ends and is the mechanism by which most domestic species evolved. Most domesticates have their origin in one of a few historic centers of domestication as farm animals. Two notable exceptions are cats and dogs. Wolf domestication was initiated late in the Mesolithic when humans were nomadic hunter-gatherers. Those...

BACKGROUND Since Pars Abad district had been known as a focus of visceral leishmaniasis (VL) in Ardabil Province but the prevalence of the disease in nomadic tribes has not been determined, thus, this study was conducted. METHODS This descriptive cross-sectional study was conducted on children up to 12yr old of nomadic tribes from Pars Abad County, Ardabil Province, Iran in 2015. For each ind...

A nomadic information environment is a heterogeneous assemblage of interconnected technological and organizational elements, which enables physical and social mobility of computing and communication services between organizational actors both within and across organizational borders. We analyze such environments based on their prevalent features of mobility, digital convergence, and mass scale....

Internet access by nomadic users roaming on a mobile network presents a scenario of access that is substantially different from the wired network. With current Web caching technology, accessing the Web while mobile is slow not only because of bandwidth limitations, but also due to moving away from the home Web caching proxy. Furthermore, current Web caching strategies ignore Web access patterns...

BACKGROUND Dermatophytic infections are a worldwide public health problem. In Nigeria, children of nomadic herdsmen are thought to be more at risk because of their early and continuous exposure to different kinds of animals. However, little is known about the level of infection in these children in southeastern Nigeria or elsewhere within the West African sub-region. OBJECTIVE This study inve...

Models of territorial defence tend to omit two characteristics of many territorial systems: repeated intrusions by the same individual and the learning processes of residents and intruders. Here we present state-dependent, dynamic models of feeding territories, designed to investigate temporal patterns of resident aggression towards intruders that are capable of spatial learning. We compare two...

PUMAS is a framework based on agents and an approach Peer to Peer (P2P), which allows to nomadic user to access several sources of information through different types of devices, eventually mobile. PUMAS provides to nomadic user information adapted to her /his preferences and to the character istics of the context of use (composed of character istics such as l...
