The design and implementation of a 1.9GHz radio frequency transmit beacon is presented. The beacon is completely selfcontained, and all necessary energy is scavenged through solar and vibrational energy sources. Custom RF integrated circuitry and energy scavenging devices are used to create a highly integrated and efficient beacon. The 1.9GHz direct modulated transmitter uses a micromachined re...

A secondary mutation (T790M) in epidermal growth factor receptor (EGFR) is a hallmark of acquired resistance to EGFR inhibitors used to treat non-small-cell lung cancer (NSCLC). Therefore, identifying the T790M mutation is crucial to guide treatment decisions. Given that DNA sequencing methods are time-consuming and insensitive, we developed and investigated the feasibility of using molecular b...

In this paper, a novel localization approach based on the use of a mobile beacon is proposed for wireless sensor networks. The localization system consists of a mobile beacon and beacon receiving modules on each sensor node for measuring distance. The localization is based on the application of multidimensional scaling technique and a local map registration approach. The approach is designed to...

Molecular beacon deoxyribonucleic acid computing is new research focus of intelligent control theory in recent years, it is also new bionic algorithm. It is well known that a very important problem how to determine or tune the proportional integral derivative controller parameters, because these parameters have a great influence on the stability and the performance of the control system. Parame...

Forty-nine samples with known C2V3 sequences were used for the evaluation of an env-based molecular beacon assay to distinguish between the two genetic subclusters C and C' which characterize the HIV-1 epidemic in Ethiopia. Two subcluster C and two subcluster C' beacons targeting two different loci in the C2V3 region were developed. Using a three beacon-based (2C and 1C'=C prime), isothermal am...

In the Universal Traffic Management Systems (UTMS) now being studied and developed in Japan, the infrared beacon (referred to as IR beacon from now on) is used for realizing the Dynamic Route Guidance System (DRGS) in real world. In DRGS, the IR beacon receives an optional destination information a driver specified, and immediately sends back to the vehicle the dynamic route guidance informatio...

Millimeter-wavelength Rayleigh scattering from water droplets in a cloud is proposed as a means of generating a bright beacon for measuring the surface profile of a radio telescope. A λ=3  mm transmitter, with an output power of a few watts, illuminating a stratiform cloud, can generate a beacon with the same flux as Mars in 10 GHz bandwidth, but the beacon has a narrow line width, so it is ext...

Stanford’s Integrity Beacon Landing System uses ground-based pseudo-satellite transmitters known as Integrity Beacons to resolve carrier phase ambiguities on final approach, giving IBLS both high integrity and centimeter-level accuracy. This paper discusses two improved Integrity Beacon designs and the results of flight tests with these new beacons. The original Integrity Beacons were not synch...

In the trilateration of wireless sensor networks, to overcome the affection of localization error caused by the selection of beacon nodes, a selective strategy of beacon nodes based on the angle information is proposed in this paper. By the comparative analysis of angle, we can determine the topology shape of the selected beacon nodes and the position relationship with unknown node, so that unk...

Motivated by how humans perceive geometry and color to recognize objects, we propose a boundary embedded attentional convolution (BEACon) network for point cloud instance segmentation. At the core of BEACon, introduce weight in layer adjust neighboring features, with being adapted relationship between changes. As result, BEACon makes use both information, takes as an important feature, thus lea...
