developed in 1991, nucleic acid sequence-based amplification (nasba) has been introduced as a rapid molecular diagnostic technique, where it has been shown to give quicker results than pcr, and it can also be more sensitive. this paper describes the development of a molecular beacon-based multiplex nasba assay for simultaneous detection of hiv-1 and hcv in plasma samples.a well-conserved region...

Abstract The KM3NeT collaboration is currently deploying the first detection units of a neutrino observatory in Mediterranean Sea, which, once completed, will be equipped with thousands so-called digital optical modules. In addition to has designed an independent calibration unit, housing set instruments, including e.g. acoustic beacon and laser beacon. unit embedded software developed operate ...

A significant contributor to the total energy consumed on many battery-powered mobile devices is the wireless network interface card (NIC). Therefore, minimizing the energy consumption of the NIC can result in significant battery life improvement for a mobile device. One way of achieving this is to transition the NIC to a lower-power sleep mode when possible For example, the IEEE 802.11 wireles...

We study the attraction trajectory of a point under the beacon model. We show that when a point object p is attracted to a point beacon b, inside a simple polygon P , its trajectory is at most √ 2 times the geodesic distance between p and b in P .

This paper presents an optimization of PSM to improve its energy conservation. According to PSM, time is divided into beacon intervals. At the beginning of each beacon interval, all stations must be awake during a specific period called ATIM window to be able to send and receive synchronization messages and announcements of buffered data frames. PSM specifies that a station having sent or recei...

One of the most important tasks in sensor networks is to determine the physical location of sensory nodes as they may not all be equipped with GPS receivers. In this paper we propose a localization method for wireless sensor networks (WSNs) using a single mobile beacon. The sensor locations are maintained as probability distributions that are sequentially updated using Monte Carlo sampling as t...

We investigated three probe design strategies used in quantitative polymerase chain reaction (PCR) for sensitivity in detection of the PCR amplicon. A plasmid with a 120-bp insert served as the DNA template. The probes were TaqMan, conventional molecular beacon (MB), and shared-stem molecular beacon (ATssMB and GCssMB). A shared-stem beacon probe combines the properties of a TaqMan probe and a ...

Alteration of fresh rock surfaces proceeds very rapidly in most terrestrial environments so that initial stages of modification of newly exposed surfaces are quickly masked by subsequent aqueous weathering processes. The hyper-arid and hypothermal environment of Beacon Valley, Antarctica, is limited in terms of available liquid water and energy available for alteration, which severely slows wea...

INTRODUCTION The Beacon Communities for Public Health (BCPH) project was launched in 2011 to gain a better understanding of the range of activities currently being conducted in population- and public health by the Beacon Communities. The project highlighted the successes and challenges of these efforts with the aim of sharing this information broadly among the public health community. BACKGRO...

This paper proposes a conceptual design for a distributed system of very simple robots capable of performing a useful realworld mission such as mapping the interior of a building overnight with a swarm of possibly hundreds of cockroach-sized robots. Presentation of this system concept follows an initial discussion of strategies for developing distributed robotic systems. Success is dependent on...
