BACKGROUND Decline in verbal episodic memory is a core feature of amnestic mild cognitive impairment (aMCI). The delayed story recall (DSR) test from the Adult Memory and Information Processing Battery (AMIPB) discriminates MCI from normal aging and predicts its conversion to Alzheimer's dementia. However, there is no study that validates the Chinese version of the DSR and reports cut-off score...

For Design Science Research (DSR) to gain wide credence as a research paradigm in Information Systems (IS), it must contribute to theory. “Theory cannot be improved until we improve the theorizing process, and we cannot improve the theorizing process until we describe it more explicitly, operate it more self-consciously, and decouple it from validation more deliberately” (Weick 1989, p. 516). W...

We describe firstly the basic features of quantum κ-Poincaré symmetries with their Hopf algebra structure. The quantum κ-Poincaré framework in any basis relates rigidly the quantum κ-Poincaré algebra with quantum κ-Poincaré group, noncommutative space-time and κ-deformed phase space. Further we present the approach of Doubly Special Relativity (DSR) theories, which introduce (in the version DSR...

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...
