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 ...

The ability to visualize mRNA in single living cells and monitor in real-time the changes of mRNA level and localization can provide unprecedented opportunities for biological and disease studies. However, the mRNA detection specificity and sensitivity are critically dependent on the selection of target sequences and their accessibility. We carried out an extensive study of the target accessibi...

During the SEEK-2 Rocket Campaign in August 2002, a Dual Band Beacon (DBB) transmitting to Ground Receivers provided unique data on E-Region electron densities. Information from two rocket beacons and four ground receivers yielded multiple samples of E-region horizontal and vertical variations. The radio beacon measurements were made at four sites (Uchinoura, Tarumizu, Tanegashima, Takazaki) in...

background: previous literatures have shown a transient ischemic attack  (tia) mimic rate  of 9-31%. we aimed  to ascertain the proportion of stroke mimics amongst suspected tia patients. methods: a prospective observational study was performed in   ghaem   hospital,   mashhad,   iran   during   2012-2013. consecutive tia patients  were identified in a stroke center. the  initial diagnosis  of ...

IEEE 802.15.4a standard based geographical routing provides low data rate connectivity at a very small power consumption and low complexity to inexpensive devices. The existing geographical relies on finding the least power consuming path by creating and maintaining routing tables. Beacon packets are used for computing power and energy consumption between two nodes. This power and energy consum...
