Abstracl--A model to implement parallel search of compressed or distributed pattern recognition codes in a neural network hierarchy is introduced. The search process functions well with either Jast learning or slow h'arning, and can robustly cope with sequences of asynchronous input patterns in real-time. The search process emerges" when computational properties of the chemical synapse, such as...

The stochastic observability of simultaneous receiver and transmitter localization is studied. A mobile vehicle-mounted receiver is assumed to draw pseudorange measurements from multiple unknown radio frequency (RF) transmitters and to fuse these measurements through an extended Kalman filter (EKF) to simultaneously localize the receiver and transmitters together with estimating the receiver’s ...

Transmitters are used to pass data stream through transmission lines in either current or voltage mode. In high data rate applications, the output impedance of transmitters should match the transmission lines’ characteristic impedance and should be tunable in order to compensate the process, voltage, and temperature variations. The multiplexing technique can be used to extend transmitters signa...

Neuromodulation is a fundamental process in the brain that regulates synaptic transmission, neuronal network activity and behavior. Emerging evidence demonstrates that astrocytes, a major population of glial cells in the brain, play previously unrecognized functions in neuronal modulation. Astrocytes can detect the level of neuronal activity and release chemical transmitters to influence neuron...

A small area study of cancer incidence, 1974-1986, near 20 high power television (TV) and frequency modulation (FM) radio transmitters in Great Britain was carried out to place in context the findings of an earlier study around the Sutton Coldfield transmitter. The national database of postcoded cancer registrations was used with population and socioeconomic data from the 1981 census. Cancers e...

• It connects to a distribution network to receive from the head-end the content for transmission • It optionally performs program re-multiplexing according to location-specific requirements • It modulates the output signal in compliance with the broadcasting technology in question • In a Single Frequency Network (SFN), which requires tight signal timing coordination, it synchronizes its output...
