In this study, a mine production management application (app) using Bluetooth beacon and tablet PC was developed to support the efficient operation of an underground loading-transport system. The app receives signals from beacons attached major loading points crushing sites through mounted on truck records time were received as well location truck. addition, when signal beacon, driver can selec...

Traditional antibody-based affinity sensing strategies employ multiple reagents and washing steps and are unsuitable for real-time detection of analyte binding. Aptamers, on the other hand, may be designed to monitor binding events directly, in real-time, without the need for secondary labels. The goal of the present study was to design an aptamer beacon for fluorescence resonance energy transf...

DOI: 10.1002/adfm.200901175 A conjugated polymer (CP) and molecular-beacon-based solid-state DNA sensing system is developed to achieve sensitive, label-free detection. A novel conjugated poly(oxadiazole) derivative exhibiting amine and thiol functional groups (POX-SH) is developed for unique chemical and photochemical stability and convenient solid-state on-chip DNA synthesis. POX-SH is solubl...

In a vehicular ad hoc network (VANET), the periodic exchange of single-hop status information broadcasts (beacon frames) produces channel loading, which causes channel congestion and induces information conflict problems. To guarantee fairness in beacon transmissions from each node and maximum network connectivity, adjustment of the beacon transmission power is an effective method for reducing ...

In this paper, we present a Link-16-based tactical data link (TDL) simulator with cognitive antijamming capability (CAJC). CAJC improves antijamming capability of existing TDL by adding the cognitive radio (CR) spectrum sensing-based jammer detection. In the presented TDL, each terminal that senses (or detects) the jammer signal can avoid the jammer spectrum opportunistically. For jammer signal...

A novel strategy of dual signal amplification was developed using circular strand-replacement DNA polymerization with a molecular beacon as a switch and silver enhancement on magnetic nanoparticles for the specific Raman spectroscopic detection of DNA down to the sub-picomolar level.

By employing DNAzyme as a recognition group and amplifier, and DNA-stabilized silver nanoclusters (DNA/AgNCs) as signal reporters, we reported for the first time a label-free catalytic and molecular beacon as an amplified biosensing platform for highly selective detection of cofactors such as Pb(2+) and L-histidine.

1. Summary Microwave indoor propagation offers a good opportunity for object positioning. The use of the pulse radar method for measuring distances and angles are quite unsuitable for indoor applications. The resolution of this method is too low and there is a minimal distance requirement of the pulse radar measurement that is usually higher than the room size. In this paper the phase method of...

We have combined an allosteric molecular beacon for target recognition and guanine-rich DNAzyme for signal amplification to develop a new platform for visual detection of nucleic acids with single-base mismatch detection capability. The fully DNA-structured platform can undergo color change in response to target DNA/RNA, which enables sensitive and selective visual detection in biological samples.
