Radio labeling is derived from the assignment of radio frequencies (channels) to a set of transmitters. The frequencies assigned depend on the geographical distance between the transmitters: the closer two transmitters are, the greater the potential for interference between their signals. Thus when the distance between two transmitters is small, the difference in the frequencies assigned must b...

The paper considers a random multiple access channel communication scenario with an unknown number of transmitters. The collection of active transmitters remains fixed during each epoch, but neither the transmitters nor the receiver know which subset of transmitters that is nor even the number of active transmitters. The receiver discerns from the channel output both the number of active transm...

Context. Wild pigs are an invasive species linked to numerous negative impacts on natural and anthropogenic ecosystems in many regions of the world. Robust estimates of juvenile wild pig survival are needed to improve population dynamics models to facilitate management of this economically and ecologically important invasive species. Despite this critical knowledgegap, todate no successful know...

Flow of current in the synaptic cleft can influence diffusion of charged transmitters, such as glutamate. In this issue of Neuron, Sylantyev et al. (2013) demonstrate how this can modulate synaptic NMDA receptor-mediated responses via a surprising mechanism-perisynaptic metabotropic glutamate receptors.

In the current vehicle coexist electronic and communications systems whose advantages are clear for the user but whose possible problems are not contrasted. The increasing use of radio frequency transmitters by automobile users makes it necessary to evaluate the risk caused by the coexistence of information and communication technologies in the reduced space inside the vehicle. In this AbstrAct

Radiotransmitters are widely used in wildlife ecology, often providing data that cannot be collected using other methods. However, negative effects have been associated with the use of transmitters for some species. We evaluated the effects and performance of 4 radiotransmitter types for use with surf and white-winged scoters (Melanitta perspicillata and M. fusca): COEXT—coelomically implanted ...
