We report that the hydrogen-bonding pattern in a molecular beacon can be replaced by metal-dependent pairs of Hg(2+) and DNA thymine (T) bases. A molecular beacon based on T-Hg(2+)-T exhibits a lower background signal and higher thermostability than regular molecular beacons.

Bluetooth Low Energy (BLE) Beacons gain high popularity due to their low consumption of energy and, thereby, long lifetime. Using the BLE protocol, these devices emit advertisement packets at fixed intervals for a short duration. Indoor localization solutions aim to provide an accurate, low cost estimate of sub-room indoor positioning. There are various techniques proposed for this purpose. BLE...

Resonance frequency analysis (RFA) is the most extended method for measuring implant stability. The stability quotient (ISQ) measure obtained by different RFA devices; however, inter- and intra-rater reliability agreement of these instruments remain unknown. Thirty implants were placed in three pig mandibles. ISQ was measured parallel perpendicular (lingual) to peg axis with Osstell® Beacon, Pe...

Bluetooth Low Energy beacons have immense potential to provide rich contextual information to smartphone applications and people by bridging the physical and digital worlds. Beacons perform the simple operation of periodically chirping URLs, locations, and other pointers, however, today’s beacons use relatively large and battery powered implementations. To truly make these beacons pervasive, th...

Plant cold shock domain proteins (CSDP) participate in maintenance of plant stress tolerance and in regulating their development. In the present paper we show that two out of three extremophyte plant Eutrema salsugineum proteins EsCSDP1-3, namely EsCSDP1 and EsCSDP3, possess high DNA-melting activity. DNA-melting activity of proteins was evaluated using molecular beacon assay in two ways: by me...

Road safety applications are one of the main incentives to deploy vehicular networks. These applications rely on periodic message exchange among vehicles (known as beaconing). The beacon messages contain information about the environment which is used to perceive dangerous situations and alert the drivers. The inter-beacon delay is the time between two consecutive beacons received from a car. I...

The design of a low-cost beacon receiver based on software defined radio is presented. The motivation for such a receiver is to investigate atmospheric impairments at the Ka frequency band. The receiver has been tested by the Hotbird 13A, ASTRA 3B and Alphasat satellite beacon signals. A GNU Radio software development toolkit and a USRP device were used for the development of a beacon receiver ...
