Hematopoietic stem cells (HSCs) are identified by their ability to sustain prolonged blood cell production in vivo, although recent evidence suggests that durable self-renewal (DSR) is shared by HSC subtypes with distinct self-perpetuating differentiation programs. Net expansions of DSR-HSCs occur in vivo, but molecularly defined conditions that support similar responses in vitro are lacking. W...

-Sensor networks consist of large number of nodes with limited energy, computation and transmission power. Each node in the network helps every other node by forwarding their packets to reach the destination .Since these nodes operate in a physically insecure environment; they are vulnerable to different types of attacks such as sinkhole and wormhole. These attacks can inject malicious packets ...

An ad-hoc network is a cluster of wireless mobiles nodes which are self-making, self-arranging and selfregulating. Numerous energy conserving routing conventions have been proposed for Mobile Ad Hoc Network (MANET). Those conventions demonstrate that energy utilization in MANET can be reduced by modifying the transmit energy to a base level. To decide the base transmit power is a testing issue....

We use Attainable Region (AR) techniques to generate reactor network synthesis solutions to the WGS reaction system. We do this using the conventional method as described by Nicol et al. (1997) to generate the candidate AR (AR) for exothermic reversible reactions in three dimensions. We compare the results with two other automated techniques, namely: the isostate algorithm (Rooney et al. 2000) ...

The highly dynamic character of a mobile ad-hoc network (MANET) poses significant challenges on network communications and resource management. Previous work on routing in MANETs has resulted in numerous routing protocols that aim at satisfying constraints such as minimum hop/distance or low energy. Existing routing protocols often fail to discover stable routes between source and sink when rou...

Design and analysis of routing protocols are the key issues for a mobile ad hoc network (MANET). The Dynamic Source Routing (DSR) protocol is one of the important on-demand routing protocols. In this paper, we develop a comprehensive analytic model for the performance study of the DSR protocol with multiple routes. Two performance metrics, called probability of a successful data transmission an...

The specific features of mobile ad hoc networks (MANETs) impose new requirements for routing protocols. The aim of this paper is to present an approach that enhances routing performance by integrating ad hoc related characteristics. We propose a loop-free adaptive path energy conserving scheme which attempts to minimize both routing and storage overhead in order to efficiently provide robustnes...

aBstraCt Due to the new technology development, mobile ad hoc networks are becoming very important. The nodes that make up the mobile ad hoc network are battery powered. The problem of conserving energy at nodes is very important and a challenging one. In this article we present an Energy Aware Multi-path Dynamic Source Routing protocol (EA-MPDSR). This protocol is based on the existing on-dema...

One of the important research characteristic in the Mobile Ad hoc NETworks (MANETs) is routing. Development of efficient routing protocol is a necessity to improve the performance of routing. We propose an Efficient Interference Aware Multipath Dynamic Source Routing Protocol (EIAM-DSR) based on Dynamic Source Routing (DSR) protocol for MANETs. The main aim of the proposed routing protocol is t...

Quality of Service (QoS) in Mobile Ad hoc Networks (MANETs) is a challenging task because of restricted resource and dynamic configuration. To support QoS, the link state information i.e. bandwidth, delay, cost, jitter, node energy and error rate in the network should be existed and manageable. The concentration of this paper is exploring the scope to QoS routing mechanism, to report the source...
